Disclosure of credit risk exposure [abstract]
Credit Risk	Loans and advances at amortised cost by product The table below presents a breakdown of loans and advances at amortised cost and the impairment allowance with stage allocation by asset classification. Impairment allowance under IFRS 9 considers both the drawn and the undrawn counterparty exposure. For retail portfolios, the total impairment allowance is allocated to the drawn exposure to the extent that the allowance does not exceed the exposure, as expected credit loss (ECL) is not reported separately. Any excess is reported on the liability side of the balance sheet as a provision. For wholesale portfolios, the impairment allowance on the undrawn exposure is reported on the liability side of the balance sheet as a provision.

Business activity reported within Credit cards, unsecured loans and other retail lending portfolio includes GAP portfolio acquisition in US cards of £2.7bn. 2 In H122, gross write-offs amounted to £560m (H121: £606m) and post write-off recoveries amounted to £20m (H121: £15m). Net write-offs represent gross write-offs less post write-off recoveries and amounted to £540m (H121: £591m). 3 Other financial assets subject to impairment excluded in the tables above include cash collateral and settlement balances, financial assets at fair value through other comprehensive income and other assets. These have a total gross exposure of £173.9bn (December 2021: £135.5bn) and impairment allowance of £138m (December 2021: £104m). This comprises £7m ECL (December 2021: £4m) on £172.1bn Stage 1 assets (December 2021: £135.3bn), £2m (December 2021: £0m) on £1.7bn Stage 2 fair value through other comprehensive income assets, cash collateral and settlement assets (December 2021: £65m) and £129m (December 2021: £100m) on £133m Stage 3 other assets (December 2021: £100m). 4 Refinements to models used for calculation reported within Credit cards, unsecured loans and other retail lending portfolio include a £0.3bn movement in US cards. These reflect methodology changes made during the year. Barclays continually review the output of models to determine accuracy of the ECL calculation including review of model monitoring, external benchmarking and experience of model operation over an extended period of time. This ensures that the models used continue to reflect the risks inherent across the businesses. 5 The £0.2bn of disposals reported within Credit cards, unsecured loans and other retail lending portfolio relates to sale of NFL portfolio within US cards.

Economic uncertainty adjustments have been applied to customers and clients considered most vulnerable to rising costs and supply chain disruption. As a result, ECL is higher than would be the case if it were based on forecast economic scenarios alone. The measurement of modelled ECL involves complexity and judgement, including estimation of probabilities of default (PD), loss given default (LGD), a range of unbiased future economic scenarios, estimation of expected lives, estimation of exposures at default (EAD) and assessing significant increases in credit risk. The Barclays Bank Group uses a five-scenario model to calculate ECL. An external consensus forecast is assembled from key sources, including HM Treasury (short and medium term forecasts), Bloomberg (based on median of economic forecasts) and the Urban Land Institute (for US House Prices), which forms the Baseline scenario. In addition, two adverse scenarios (Downside 1 and Downside 2) and two favourable scenarios (Upside 1 and Upside 2) are derived, with associated probability weightings. The adverse scenarios are calibrated to a broadly similar severity to Barclays’ internal stress tests and stress scenarios provided by regulators whilst also considering IFRS 9 specific sensitivities and non-linearity. The favourable scenarios are designed to reflect plausible upside risks to the Baseline scenario which are broadly consistent with the economic narrative approved by the Senior Scenario Review Committee. All scenarios are regenerated at a minimum semi-annually. The scenarios include key economic variables, (including GDP, unemployment, House Price Index (HPI) and base rates in both the UK and US markets), and expanded variables using statistical models based on historical correlations. The upside and downside shocks are designed to evolve over a five-year stress horizon, with all five scenarios converging to a steady state after approximately seven years. Scenarios used to calculate the Barclays Bank Group’s ECL charge were refreshed in Q222. The current Baseline scenario reflects the latest consensus economic forecasts. Unemployment rates remain low, close to current levels. As inflation expectations drift higher, central banks tighten monetary policy sharply. In 2023, the UK Bank Rate reaches 2.75%, while the US Federal Funds Rate peaks at 3.25%. Rising borrowing charges and falling real wages subtract from growth through lower investment and household consumption. In the Downside 2 scenario, with inflation expectations rising, the central banks have to raise interest rates very sharply. The UK Bank Rate and the US Federal Funds Rate both reach 5.0% in Q223. Higher borrowing costs derail the economy and unemployment peaks in Q124 at 9.2% in the UK and 9.5% in the US. Given already stretched valuations, the sharp increase in mortgage servicing costs sees house prices decrease very sharply. In the Upside 2 scenario, supply disruptions are resolved, while the aggregate demand is supported by a release of household savings. GDP growth accelerates. Recovering labour force participation limits domestic inflationary pressures, while lower energy prices add some downward pressure on prices globally. The methodology for estimating probability weights used in calculating ECL involves simulating a range of future paths for UK and US GDP using historical data. The five scenarios are mapped against the distribution of these future paths, with the median centred around the Baseline such that scenarios further from the Baseline attract a lower weighting. A single set of five scenarios is used across all portfolios and all five weights are normalised to equate to 100%. The same scenarios and weights that are used in the ECL estimation are also used for Barclays’ internal planning purposes. The impacts across the portfolios are different because of the sensitivities of each of the portfolios to specific macroeconomic variables. For example, mortgages are highly sensitive to house prices; credit cards and unsecured consumer loans are highly sensitive to unemployment. The decrease in the Upside scenario weightings and increase in the Baseline weighting were driven by: (i) continued growth in UK/US GDP which resulted in a narrower range of future GDP paths; and (ii) generally less favourable GDP projections across scenarios, increasing the distance between Upside 2 and Baseline scenario paths. For further details see page 16. COVID-19 related expert judgements have been materially replaced by provisions for customers and clients considered most vulnerable to rising costs and supply chain disruption. The economic uncertainty adjustments of £0.7bn (FY21: £1.0bn) have been applied as overlays to the modelled ECL output. These adjustments consist of a customer uncertainty provision of £0.6bn (FY21: £0.9bn) and a model uncertainty provision of £0.1bn (FY21: £0.1bn). For further details, see pages 11 to 12. The tables below show the key consensus macroeconomic variables used in the scenarios (five-year annual paths), the probability weights applied to each scenario and the macroeconomic variables by scenario using ‘specific bases’, i.e. the most extreme position of each variable in the context of the scenario, for example, the highest unemployment for downside scenarios and the lowest unemployment for upside scenarios. The five-year average table provides additional transparency.

Disclosure of initial application of standards or interpretations [abstract]
Basis of preparation	Basis of preparation These condensed consolidated interim financial statements (the financial statements) for the six months ended 30 June 2022 have been prepared in accordance with (a) the Disclosure Guidance and Transparency Rules (DTR) of the UK’s Financial Conduct Authority (FCA), and (b) (i) UK adopted IAS 34, Interim Financial Reporting (ii) IAS 34, Interim Financial Reporting, as published by the International Accounting Standards Board (IASB), and (iii) IAS 34, Interim Financial Reporting as adopted pursuant to Regulation (EC) No 1606/2002 as it applies in the European Union (EU). UK adopted IAS 34 and EU adopted IAS 34 are currently the same and were the same as at 30 June 2022. The condensed consolidated interim financial statements should be read in conjunction with the annual financial statements for the year ended 31 December 2021. The annual financial statements for the year ended 31 December 2021 were prepared in accordance the requirements of the Companies Act 2006 and in accordance with (i) UK-adopted international accounting standards (ii) International Financial Reporting Standards (IFRS) and interpretations (IFRICs) as issued by the IASB and (iii) IFRS adopted pursuant to Regulation (EC) No 1606/2002 as it applies in the EU . UK adopted IFRS and EU adopted IFRS are currently the same and were the same as at 31 December 2021. The accounting policies and methods of computation used in these condensed consolidated interim financial statements are the same as those used in the Barclays Bank PLC Annual Report on Form 20-F for the financial year ended 31 December 2021, as amended (the Annual Report 2021). 1. Going concern The financial statements are prepared on a going concern basis, as the Directors are satisfied that the Barclays Bank Group and parent company have the resources to continue in business for a period of at least 12 months from approval of the interim financial statements. In making this assessment, the Directors have considered a wide range of information relating to present and future conditions which includes a review of a working capital report (WCR). The WCR is used by the Directors to assess the future performance of the Barclays Bank Group and that it has the resources in place that are required to meet its ongoing regulatory requirements. The WCR includes an assessment of the impact of internally generated stress testing scenarios on the liquidity and capital requirements forecasts. The stress tests used were based upon an assessment of reasonably possible downside economic scenarios that the Barclays Bank Group could experience. The WCR indicated that the Barclays Bank Group had sufficient capital in place to support its future business requirements and remained above its regulatory minimum requirements in the internal stress scenarios. 2. Other disclosures The Credit risk disclosures on pages 7 to 18 form part of these interim financial statements. Restatement of financial statements The comparatives in these condensed consolidated interim financial statements for the six months ended 30 June 2022 (the financial statements) have been restated to reflect both a provision and contingent liability disclosure in respect of the impact of an over-issuance of securities (Over-issuance of Securities) in excess of the maximum aggregate offering price registered under Barclays Bank PLC’s shelf registration statement on Form F-3, as declared effective by the SEC in August 2019 (2019 F-3) and Barclays Bank PLC’s predecessor shelf registration statement on Form F-3 filed in 2018 (Predecessor Shelf). Due to a historic SEC settlement order, at the time the 2019 F-3 was filed and the Predecessor Shelf was amended, Barclays Bank PLC had ceased to be a “well-known seasoned issuer” (or WKSI) and had become an “ineligible issuer”, as defined in Rule 405 under the Securities Act of 1933, as amended (Securities Act), thus being required to register upfront a certain amount of securities with the SEC. In March 2022, Barclays Bank PLC became aware that it had issued securities in the US materially in excess of the amount it had registered with the SEC under the 2019 F-3 and subsequently became aware that securities had also been issued in excess of the amount it had registered with the SEC under the Predecessor Shelf. The securities that were issued in this period comprise structured notes and exchange traded notes (ETNs). As such, certain offers and sales of these securities were not made in compliance with the Securities Act, giving rise to rights of rescission for certain purchasers of the securities. Under Section 12(a)(1) of the Securities Act, certain purchasers of unregistered securities have a right to recover, upon the tender of such security, the consideration paid for such security with interest, less the amount of any income received, or damages if the purchaser no longer owns the security (the Rescission Price). As a result, Barclays Bank PLC has elected to make a rescission offer to eligible purchasers of the relevant affected securities at the Rescission Price (the Rescission Offer). A proportion of the expected costs associated with the rights of rescission of certain investors are attributable to Barclays Bank PLC’s financial statements for the year ended 31 December 2021. Accordingly, the comparatives in these financial statements have been restated. The restatement impacts the consolidated income statement, the parent company income statement, the consolidated statement of comprehensive income, the parent company statement of comprehensive income, the consolidated balance sheet, the parent company balance sheet, the consolidated statement of changes in equity, the parent company statement of changes in equity, the consolidated cash flow statement, and the parent company cash flow statement for the year ended 31 December 2021, as well as half yearly financial information that is presented within this document. There was no material effect on Barclays Bank PLC’s previously reported financial statements for the years ended 31 December 2020 and 2019.

Barclays Bank Group has corrected the presentation of the scheme fees incurred when Barclays acts as an “acquirer” as part of the payment transaction cycle. From 2022 onwards, the scheme fees reported under "Consumer, Cards and Payments" are presented within fees and commission income under “Transactional” fee type, which had previously been recognised in fees and commission expense. The reclassification into Fee and Commission income is a reduction of £94m for H122. The comparatives have not been restated as the effect is not considered material although the effect would have been a reduction of H121: £81m with no impact on Net fee and commission income. There is no impact on Net assets or Cash flows reported. Transactional fees are service charges on deposit accounts, cash management services and transactional processing fees. These include interchange and merchant fee income generated from credit and bank card usage. Advisory fees are generated from wealth management services and investment banking advisory services related to mergers, acquisitions and financial restructurings. Brokerage and execution fees are earned for executing client transactions with various exchanges and over-the-counter markets and assisting clients in clearing transactions. Underwriting and syndication fees are earned for the distribution of client equity or debt securities, and the arrangement and administration of a loan syndication. These include commitment fees to provide loan financing.

Major components of tax expense (income) [abstract]
Tax	Tax The tax charge for H122 was £476m (restated 1 H121: £594m), representing an effective tax rate (ETR) of 18.3% (restated H121: 18.2%). The ETR for H122 includes a charge recognised for the re-measurement of the Barclays Bank Group’s UK deferred tax assets (DTAs) due to the enactment of legislation in Q122 which will result in the UK banking surcharge rate being reduced from 8% to 3% effective from 1 April 2023. The ETR excluding the impact of this downward re-measurement of UK DTAs was 11.2% which includes a 5.7% benefit relating to adjustments in respect of prior years. The H121 ETR included a benefit recognised for the re-measurement of the Barclays Bank Group’s UK DTAs as a result of the enactment of legislation to increase the UK corporation tax rate to 25% effective from 1 April 2023. The re-measurement of UK DTAs has resulted in the Barclays Bank Group’s UK DTAs decreasing by £100m with a tax charge in the income statement of £183m and a tax credit within other comprehensive income of £83m. In October 2021, the OECD and G20 Inclusive Framework on Base Erosion and Profit Shifting announced plans to introduce a global minimum tax rate of 15%. The model rules were released by the OECD in December 2021 with further guidance published in March 2022. Draft legislation published by the UK government on 20 July 2022 to implement the global minimum tax regime is expected to apply for accounting periods beginning on or after 31 December 2023. The Barclays Bank Group is reviewing the published OECD model rules and guidance and will review further guidance as well as new legislation to be released by governments implementing this new tax regime to assess the potential impact of new legislation. In the USA, the proposed Build Back Better Act was passed by the House of Representatives in 2021 but it was not passed by the Senate and it is uncertain whether various proposals contained in the Act will progress further. The Act included proposals to implement material changes to international tax provisions, including amendments to the Base Erosion and Anti-Abuse Tax and the imposition of an alternative minimum tax based on accounting profits. It is unclear at this time whether any of these proposals could have a significant impact on the Barclays Bank Group if enacted. The Barclays Bank Group will continue to monitor developments and assess the potential impact of any future legislative changes ultimately enacted. 1. 2021 financial metrics have been restated to reflect the impact of the Over-issuance of Securities.

Fair value of financial instruments	Fair value of financial instruments This section should be read in conjunction with Note 16, Fair value of financial instruments of the Barclays Bank PLC Annual Report 2021, which provides more detail about accounting policies adopted, valuation methodologies used in calculating fair value and the valuation control framework which governs oversight of valuations. There have been no changes in the accounting policies adopted or the valuation methodologies used.

Assets and liabilities reclassified between Level 1 and Level 2 During the period there were no material transfers between Level 1 and Level 2 (year ended December 2021: no material transfers between Level 1 and Level 2). Level 3 movement analysis The following table summarises the movements in the balances of Level 3 assets and liabilities during the period. The table shows gains and losses and includes amounts for all financial assets and liabilities that are held at fair value transferred to and from Level 3 during the period. Transfers have been reflected as if they had taken place at the beginning of the period. Asset and liability moves between Level 2 and Level 3 are primarily due to i) an increase or decrease in observable market activity related to an input or ii) a change in the significance of the unobservable input, with assets and liabilities classified as Level 3 if an unobservable input is deemed significant.

The effect of stressing unobservable inputs to a range of reasonably possible alternatives, alongside considering the impact of using alternative models, would be to increase fair values by up to £669m (December 2021: £555m) or to decrease fair values by up to £809m (December 2021: £651m) with substantially all the potential effect impacting profit and loss rather than reserves. Significant unobservable inputs The valuation techniques and significant unobservable inputs for assets and liabilities recognised at fair value and classified as Level 3 are consistent with those described within Note 16, Fair value of financial instruments in the Barclays Bank PLC Annual Report 2021. Fair value adjustments Key balance sheet valuation adjustments are quantified below: As at 30.06.22 As at 31.12.21 £m £m Exit price adjustments derived from market bid-offer spreads (531) (498) Uncollateralised derivative funding (82) (127) Derivative credit valuation adjustments (388) (212) Derivative debit valuation adjustments 208 91 • Exit price adjustments derived from market bid-offer spreads increased by £33m to £531m as a result of movements in market bid offer spreads. • Uncollateralised derivative funding decreased by £45m to £82m as a result of reduction in uncollateralised funding exposure due to increases in interest rates which offset the impact of wider funding spreads. • Derivative credit valuation adjustments decreased by £176m to £388m as a result of widening input counterparty credit spreads. • Derivative debit valuation adjustments decreased by £117m to £208m as a result of widening in input own credit spreads. Portfolio exemption The Barclays Bank Group uses the portfolio exemption in IFRS 13, Fair Value Measurement to measure the fair value of groups of financial assets and liabilities. Instruments are measured using the price that would be received to sell a net long position (i.e. an asset) for a particular risk exposure or to transfer a net short position (i.e. a liability) for a particular risk exposure in an orderly transaction between market participants at the balance sheet date under current market conditions. Accordingly, the Barclays Bank Group measures the fair value of the group of financial assets and liabilities consistently with how market participants would price the net risk exposure at the measurement date. Unrecognised gains as a result of the use of valuation models using unobservable inputs The amount that has yet to be recognised in income that relates to the difference between the transaction price (the fair value at initial recognition) and the amount that would have arisen had valuation models using unobservable inputs been used on initial recognition, less amounts subsequently recognised, is £106m (December 2021: £122m) for financial instruments measured at fair value and £27m (December 2021: £28m) for financial instruments carried at amortised cost. There are additions and FX gains of £19m (December 2021: £59m) and amortisation and releases of £35m (December 2021: £40m) for financial instruments measured at fair value and amortisation and releases of £1m (December 2021: £2m) offset by additions of £nil (December 2021: £nil) for financial instruments carried at amortised cost. Third party credit enhancements Structured and brokered certificates of deposit issued by the Barclays Bank Group are insured up to $250,000 per depositor by the Federal Deposit Insurance Corporation (FDIC) in the United States. The FDIC is funded by premiums that the Barclays Bank Group and other banks pay for deposit insurance coverage. The carrying value of these issued certificates of deposit that are designated under the IFRS 9 fair value option includes this third party credit enhancement. The on-balance sheet value of these brokered certificates of deposit amounted to £3,065m (December 2021: £790m). Comparison of carrying amounts and fair values for assets and liabilities not held at fair value Valuation methodologies employed in calculating the fair value of financial assets and liabilities measured at amortised cost are consistent with those described within Note 16, Fair value of financial instruments in the Barclays Bank PLC Annual Report 2021. The following table summarises the fair value of financial assets and liabilities measured at amortised cost on the Barclays Bank Group’s balance sheet: As at 30.06.22 As at 31.12.21 Carrying amount Fair value Carrying amount Fair value Financial assets £m £m £m £m Loans and advances at amortised cost 180,098 180,103 145,259 145,665 Reverse repurchase agreements and other similar secured lending 1,060 1,060 3,177 3,177 Financial liabilities Deposits at amortised cost (311,465) (311,455) (262,828) (262,843) Repurchase agreements and other similar secured borrowing (12,805) (12,807) (12,769) (12,776) Debt securities in issue (68,656) (68,504) (48,388) (48,350) Subordinated liabilities (32,241) (32,230) (32,185) (33,598)

See Restatement of financial statements (Note 1) on page 29 for further details. Over-issuance of Securities As at 30 June 2022, Barclays Bank PLC has recognised a balance sheet provision of £1,757m (December 2021: £220m) in relation to the Over-issuance of Securities (see Basis of preparation on page 29 for more information), out of which £1,592m (December 2021: £220m) is due to the over-issuance of structured notes (within customer redress), and £165m (December 2021: £nil) is in relation to liabilities that could be incurred arising out of ongoing discussions in respect of a potential SEC resolution (within legal, competition and regulatory matters). The amount of the provision in relation to the rescission rights of investors in over-issued structured notes is determined by (among other things) the market value of the structured notes subject to the Rescission Offer, participation rates in such Rescission Offer, prevailing interest rates, and movements in foreign exchange rates. The majority of the structured notes subject to the Rescission Offer provide an equity linked return to investors. As such, the value of these notes is highly sensitive to movements in the price of individual securities and a range of indices. The increase in the provision of £1,372m predominantly reflects a reduction in the market value of the structured notes and additional accrued interest that would be payable to investors on rescission. The US equity markets have been volatile during the first half of 2022, with significant reductions in the value of US equity indices such as the S&P 500 from the year end 2021 levels which has led to a reduction in the market value of the structured notes, and increased the size of the provision. The provision does not include the impact of market hedges that have been entered into subsequent to the year-end and were initiated from the end of the first quarter of 2022 to reduce the net volatility to the income statement. When determining these market hedges, consideration was given to changes in the rescission costs which would arise from volatility in the market along with the positioning of the Markets business. The structured notes also accrue interest on a monthly basis (at current prevailing interest rates and participation rate assumptions this is c£34m a month) until the Rescission Price has been paid. The provision also assumes that not all structured note investors whose securities are out of the money will accept the Rescission Offer. If all investors were to accept the Rescission Offer, the provision would increase by c£60m. The remaining increase in the provision of £165m results from Barclays Bank PLC’s estimates of the potential SEC resolution.

Disclosure of defined benefit plans [abstract]
Retirement benefits	Retirement benefits As at 30 June 2022, the Barclays Bank Group’s IAS 19 net pension surplus across all schemes was £5bn (December 2021: £3.6bn). The UK Retirement Fund (UKRF), which is the Barclays Bank Group’s main scheme, had an IAS 19 net pension surplus of £5.2bn (December 2021: £3.8bn). The movement for the UKRF was driven by an overall increase in AA corporate bond yields (used for discounting future liabilities), a reduction in long-term expected price inflation assumption and the payment of deficit reduction contributions. These movements were partially offset by the fall in the value of UKRF's assets and the impact of high recent inflation on the liabilities. UKRF funding valuations The latest annual update as at 30 September 2021 showed the funding position had improved to a surplus of £0.6bn from a deficit of £0.9bn shown as at 30 September 2020. The improvement was mainly due to £0.7bn of deficit reduction contributions and favourable asset returns, partially offset by higher expected long term price inflation. The deficit recovery plan agreed at the last triennial valuation requires deficit reduction contributions from Barclays Bank PLC of £294m in 2022 and £286m in 2023. The deficit reduction contributions are in addition to the regular contributions to meet the Group’s share of the cost of benefits accruing over each year. £147m of the 2022 deficit reduction contributions were paid in April, with the remaining £147m for 2022 due in September. The next triennial actuarial valuation of the UKRF is due to be completed in 2023 with an effective date of 30 September 2022.

Other equity instruments	Other equity instruments Other equity instruments of £9,794m (December 2021: £9,693m) are AT1 securities issued to Barclays PLC. Barclays PLC uses funds from market issuances to purchase AT1 securities from Barclays Bank PLC. There was one issuance and one redemption in the six months to 30 June 2022. The AT1 securities are perpetual securities with no fixed maturity and are structured to qualify as AT1 instruments under prevailing capital rules applicable as at the relevant issue date. AT1 securities are undated and are redeemable, at the option of Barclays Bank PLC, in whole on (i) the initial call date, or on any fifth anniversary after the initial call date or (ii) any day falling in a named period ending on the initial reset date, or on any fifth anniversary after the initial reset date. In addition, the AT1 securities are redeemable, at the option of Barclays Bank PLC, in whole in the event of certain changes in the tax or regulatory treatment of the securities. Any redemptions require the prior consent of the PRA.

As at 30 June 2022, there was a credit balance of £4,589m (December 2021: £2,581m credit) in the currency translation reserve. The £2,008m credit movement principally reflects the weakening of GBP against USD during the period. Fair value through other comprehensive income reserve The fair value through other comprehensive income reserve represents the fair value changes of fair value through other comprehensive income investments since initial recognition. As at 30 June 2022, there was a debit balance of £917m (December 2021: £118m debit) in the fair value through other comprehensive income reserve. The loss of £799m is principally driven by a £1,083m loss from the decrease in fair value of bonds due to increasing bond yields which was partially offset by a tax credit of £284m. Cash flow hedging reserve The cash flow hedging reserve represents the cumulative gains and losses on effective cash flow hedging instruments that will be recycled to the income statement when the hedged transactions affect profit or loss. As at 30 June 2022, there was a debit balance of £3,492m (December 2021: £618m debit) in the cash flow hedging reserve. The decrease of £2,874m principally reflects a £3,908m decrease in the fair value of interest rate swaps held for hedging purposes as major interest rate forward curves increased. This is partially offset by a tax credit of £1,032m. Own credit reserve The own credit reserve reflects the cumulative own credit gains and losses on financial liabilities at fair value. Amounts in the own credit reserve are not recycled to profit or loss in future periods. As at 30 June 2022, there was a debit balance of £103m (December 2021: £960m debit) in the own credit reserve. The movement of £857m principally reflects a £1,258m gain from the widening of Barclays funding spreads partially offset by a tax charge of £403m. Other reserves As at 30 June 2022, there was a debit balance of £24m (December 2021: £24m debit) in other reserves relating to redeemed ordinary and preference shares issued by Barclays Bank Group.

Legal, competition and regulatory matters
Legal, competition and regulatory matters	Legal, competition and regulatory matters The Barclays Bank Group faces legal, competition and regulatory challenges, many of which are beyond our control. The extent of the impact of these matters cannot always be predicted but may materially impact our operations, financial results, condition and prospects. Matters arising from a set of similar circumstances can give rise to either a contingent liability or a provision, or both, depending on the relevant facts and circumstances. The recognition of provisions in relation to such matters involves critical accounting estimates and judgments in accordance with the relevant accounting policies applicable to Note 8, Provisions. We have not disclosed an estimate of the potential financial impact or effect on the Barclays Bank Group of contingent liabilities where it is not currently practicable to do so. Various matters detailed in this note seek damages of an unspecified amount. While certain matters specify the damages claimed, such claimed amounts do not necessarily reflect the Barclays Bank Group’s potential financial exposure in respect of those matters. Investigations into certain advisory services agreements FCA proceedings In 2008, Barclays Bank PLC and Qatar Holdings LLC entered into two advisory service agreements (the Agreements). The Financial Conduct Authority (FCA) conducted an investigation into whether the Agreements may have related to Barclays PLC’s capital raisings in June and November 2008 (the Capital Raisings) and therefore should have been disclosed in the announcements or public documents relating to the Capital Raisings. In 2013, the FCA issued warning notices (the Notices) finding that Barclays PLC and Barclays Bank PLC acted recklessly and in breach of certain disclosure-related listing rules, and that Barclays PLC was also in breach of Listing Principle 3. The financial penalty provided in the Notices is £50m. Barclays PLC and Barclays Bank PLC continue to contest the findings. Following the conclusion of the Serious Fraud Office (SFO) proceedings against certain former Barclays executives resulting in their acquittals, the FCA proceedings, which were stayed, have resumed. A hearing took place before the Regulatory Decisions Committee in the first quarter of 2022 and a decision is expected in the second half of 2022. Investigations into LIBOR and other benchmarks and related civil actions Regulators and law enforcement agencies, including certain competition authorities, from a number of governments have conducted investigations relating to Barclays Bank PLC’s involvement in allegedly manipulating certain financial benchmarks, such as LIBOR. Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Barclays Bank Group and other banks in relation to the alleged manipulation of LIBOR and/or other benchmarks. USD LIBOR civil actions The majority of the USD LIBOR cases, which have been filed in various US jurisdictions, have been consolidated for pre-trial purposes in the US District Court in the Southern District of New York (SDNY). The complaints are substantially similar and allege, among other things, that Barclays PLC, Barclays Bank PLC, BCI and other financial institutions individually and collectively violated provisions of the US Sherman Antitrust Act (Antitrust Act), the US Commodity Exchange Act (CEA), the US Racketeer Influenced and Corrupt Organizations Act (RICO), the Securities Exchange Act of 1934 and various state laws by manipulating USD LIBOR rates. Putative class actions and individual actions seek unspecified damages with the exception of one lawsuit, in which the plaintiffs are seeking no less than $100m in actual damages and additional punitive damages against all defendants, including Barclays Bank PLC. Some of the lawsuits also seek trebling of damages under the Antitrust Act and RICO. Barclays Bank PLC has previously settled certain claims. Two class action settlements, where Barclays Bank PLC has respectively paid $7.1m and $20m have received final court approval. Barclays Bank PLC also settled two further matters for $7.5m and $1.95m, respectively. Sterling LIBOR civil actions In 2016, two putative class actions filed in the SDNY against Barclays Bank PLC, BCI and other Sterling LIBOR panel banks alleging, among other things, that the defendants manipulated the Sterling LIBOR rate in violation of the Antitrust Act, CEA and RICO, were consolidated. The defendants’ motion to dismiss the claims was granted in 2018. The plaintiffs have appealed the dismissal. Japanese Yen LIBOR civil actions In 2012, a putative class action was filed in the SDNY against Barclays Bank PLC and other Japanese Yen LIBOR panel banks by a lead plaintiff involved in exchange-traded derivatives and members of the Japanese Bankers Association’s Euroyen Tokyo Interbank Offered Rate (Euroyen TIBOR) panel. The complaint alleges, among other things, manipulation of the Euroyen TIBOR and Yen LIBOR rates and breaches of the CEA and the Antitrust Act. In 2014, the court dismissed the plaintiff’s antitrust claims, and, in 2020, the court dismissed the plaintiff’s remaining CEA claims. The plaintiff has appealed the lower court’s dismissal of such claims. In 2015, a second putative class action, making similar allegations to the above class action, was filed in the SDNY against Barclays PLC, Barclays Bank PLC and BCI. Barclays and the plaintiffs have reached a settlement of $17.75m for both actions, which is subject to court approval. SIBOR/SOR civil action In 2016, a putative class action was filed in the SDNY against Barclays PLC, Barclays Bank PLC, BCI and other defendants, alleging manipulation of the Singapore Interbank Offered Rate (SIBOR) and Singapore Swap Offer Rate (SOR). The plaintiffs and remaining defendants (which includes Barclays Bank PLC) have reached a joint settlement to resolve this matter for $91m, which has received preliminary court approval. A final court approval hearing has been scheduled for November 2022. The financial impact of Barclays’ share of the joint settlement is not expected to be material to the Barclays Bank Group’s operating results, cash flows or financial position. ICE LIBOR civil actions In 2019, several putative class actions were filed in the SDNY against a panel of banks, including Barclays PLC, Barclays Bank PLC, BCI, other financial institution defendants and Intercontinental Exchange Inc. and certain of its affiliates (ICE), asserting antitrust claims that defendants manipulated USD LIBOR through defendants’ submissions to ICE. These actions have been consolidated. The defendants’ motion to dismiss was granted in 2020 and the plaintiffs appealed. In February 2022, the dismissal was affirmed on appeal. The plaintiffs have not sought U.S. Supreme Court review. This matter is now concluded. In August 2020, an ICE LIBOR-related action was filed by a group of individual plaintiffs in the US District Court for the Northern District of California on behalf of individual borrowers and consumers of loans and credit cards with variable interest rates linked to USD ICE LIBOR. The plaintiffs’ motion seeking, among other things, preliminary and permanent injunctions to enjoin the defendants from continuing to set LIBOR or enforce any financial instrument that relies in whole or in part on USD LIBOR was denied. The defendants have moved to dismiss the case. Non-US benchmarks civil actions There remains one claim, issued in 2017 against Barclays Bank PLC and other banks in the UK in connection with alleged manipulation of LIBOR. Proceedings have also been brought in a number of other jurisdictions in Europe, Argentina and Israel relating to alleged manipulation of LIBOR and EURIBOR. Additional proceedings in other jurisdictions may be brought in the future. Credit Default Swap civil action A putative antitrust class action is pending in New Mexico federal court against Barclays Bank PLC, BCI and various other financial institutions. The plaintiffs, the New Mexico State Investment Council and certain New Mexico pension funds, allege that the defendants conspired to manipulate the benchmark price used to value Credit Default Swap (CDS) contracts at settlement (i.e. the CDS final auction price). The plaintiffs allege violations of US antitrust laws and the CEA, and unjust enrichment under state law. The defendants have moved to dismiss the case. Foreign Exchange investigations and related civil actions In 2015, the Barclays Bank Group reached settlements totalling approximately $2.38bn with various US federal and state authorities and the FCA in relation to investigations into certain sales and trading practices in the Foreign Exchange market. The European Commission announced two settlements in May 2019 and the Barclays Bank Group paid penalties totalling approximately €210m. In June 2019, the Swiss Competition Commission announced two settlements and the Barclays Bank Group paid penalties totalling approximately CHF27m. In December 2021, the European Commission announced a final settlement which required the Barclays Bank Group to pay penalties totalling approximately €54m, which amount has been provided for in previous periods. The financial impact of any ongoing investigations is not expected to be material to the Barclays Bank Group’s operating results, cash flows or financial position. Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Barclays Bank Group and other banks in relation to alleged manipulation of Foreign Exchange markets. FX opt out civil action In 2018, Barclays Bank PLC and BCI settled a consolidated action filed in the SDNY, alleging manipulation of Foreign Exchange markets (Consolidated FX Action), for a total amount of $384m. Also in 2018, a group of plaintiffs who opted out of the Consolidated FX Action filed a complaint in the SDNY against Barclays PLC, Barclays Bank PLC, BCI and other defendants. Some of the plaintiffs’ claims were dismissed in 2020. Retail basis civil action In 2015, a putative class action was filed against several international banks, including Barclays PLC and BCI, on behalf of a proposed class of individuals who exchanged currencies on a retail basis at bank branches (Retail Basis Claims). The SDNY has ruled that the Retail Basis Claims are not covered by the settlement agreement in the Consolidated FX Action. The Court subsequently dismissed all Retail Basis Claims against the Barclays Bank Group and all other defendants. The plaintiffs have filed an amended complaint. Non-US FX civil actions Legal proceedings have been brought or are threatened against Barclays PLC, Barclays Bank PLC, BCI and Barclays Execution Services Limited (BX) in connection with alleged manipulation of Foreign Exchange in the UK, a number of other jurisdictions in Europe, Israel, Brazil and Australia. Additional proceedings may be brought in the future. The above-mentioned proceedings include two purported class actions filed against Barclays PLC, Barclays Bank PLC, BX, BCI and other financial institutions in the UK Competition Appeal Tribunal (CAT) in 2019 following the settlements with the European Commission described above. The CAT refused to certify these claims in the first quarter of 2022 although the claimants are seeking permission to appeal. Also in 2019, a separate claim was filed in the UK in the High Court of Justice (High Court), and subsequently transferred to the CAT, by various banks and asset management firms against Barclays Bank PLC and other financial institutions alleging breaches of European and UK competition laws related to FX trading. Metals related civil actions A number of US civil complaints, each on behalf of a proposed class of plaintiffs, have been consolidated and transferred to the SDNY. The complaints allege that Barclays Bank PLC and other members of The London Gold Market Fixing Ltd. manipulated the prices of gold and gold derivative contracts in violation of the Antitrust Act and other federal laws. The parties have reached a joint settlement to resolve this matter for $50m, which has received preliminary court approval, with the final court approval hearing scheduled for August 2022. The financial impact of Barclays’ share of the joint settlement is not expected to be material to the Barclays Bank Group’s operating results, cash flows or financial position. A separate US civil complaint by a proposed class of plaintiffs against a number of banks, including Barclays Bank PLC, BCI and BX, alleging manipulation of the price of silver in violation of the CEA, the Antitrust Act and state antitrust and consumer protection laws, has been dismissed as against the Barclays entities. The plaintiffs have the option to seek the court’s permission to appeal. Civil actions have also been filed in Canadian courts against Barclays PLC, Barclays Bank PLC, Barclays Capital Canada Inc. and BCI on behalf of proposed classes of plaintiffs alleging manipulation of gold and silver prices. US residential mortgage related civil actions There are two pending US Residential Mortgage-Backed Securities (RMBS) related civil actions arising from unresolved repurchase requests submitted by Trustees for certain RMBS, alleging breaches of various loan-level representations and warranties (R&Ws) made by Barclays Bank PLC and/or a subsidiary acquired in 2007. In one action, the Barclays defendants’ motion for summary judgment was granted in June 2022 and the plaintiffs’ R&W breach claim was dismissed. The plaintiffs may appeal. The other repurchase action is pending. Barclays Bank PLC has reached settlements to resolve two other repurchase actions, which have received final court approval. Payment of the settlement amount of one of those repurchase actions was completed in the first quarter of 2022, and the other will be completed in the third quarter of 2022. The financial impact of the settlements is not expected to be material to the Barclays Bank Group’s operating results, cash flows or financial position. In 2020, a civil litigation claim was filed in the New Mexico First Judicial District Court by the State of New Mexico against six banks, including BCI, on behalf of two New Mexico state pension funds and the New Mexico State Investment Council relating to legacy RMBS purchases. As to BCI, the complaint alleges that the funds purchased approximately $22m in RMBS underwritten by BCI. The parties have reached a joint settlement to resolve this matter for $32.5m. The settlement was paid in April 2022. The financial impact of BCI’s share of the joint settlement is not material to the Barclays Bank Group’s operating results, cash flows or financial position. Government and agency securities civil actions Treasury auction securities civil actions Consolidated putative class action complaints filed in US federal court against Barclays Bank PLC, BCI and other financial institutions under the Antitrust Act and state common law allege that the defendants (i) conspired to manipulate the US Treasury securities market and/or (ii) conspired to prevent the creation of certain platforms by boycotting or threatening to boycott such trading platforms. The court dismissed the consolidated action in March 2021. The plaintiffs filed an amended complaint. The defendants’ motion to dismiss the amended complaint was granted in March 2022. The plaintiffs are appealing this decision. In addition, certain plaintiffs have filed a related, direct action against BCI and certain other financial institutions, alleging that defendants conspired to fix and manipulate the US Treasury securities market in violation of the Antitrust Act, the CEA and state common law. Supranational, Sovereign and Agency bonds civil actions Civil antitrust actions have been filed in the SDNY and Federal Court of Canada in Toronto against Barclays Bank PLC, BCI, BX, Barclays Capital Securities Limited and, with respect to the civil action filed in Canada only, Barclays Capital Canada, Inc. and other financial institutions alleging that the defendants conspired to fix prices and restrain competition in the market for US dollar-denominated Supranational, Sovereign and Agency bonds. In one of the actions filed in the SDNY, the court granted the defendants’ motion to dismiss the plaintiffs’ complaint. The dismissal was affirmed on appeal; however, the district court subsequently informed the parties of a potential conflict. The motion to dismiss were assigned to a new district court judge and the plaintiffs have moved to vacate the dismissal order. The plaintiffs have voluntarily dismissed the other SDNY action. In the Federal Court of Canada action, the plaintiffs reached settlements with a small number of banks in 2020 (not including Barclays Capital Canada, Inc.). The plaintiffs have commenced the class certification process. There is no court scheduled deadline and the action remains at an early stage. Variable Rate Demand Obligations civil actions Civil actions have been filed against Barclays Bank PLC and BCI and other financial institutions alleging the defendants conspired or colluded to artificially inflate interest rates set for Variable Rate Demand Obligations (VRDOs). VRDOs are municipal bonds with interest rates that reset on a periodic basis, most commonly weekly. Two actions in state court have been filed by private plaintiffs on behalf of the states of Illinois and California. Three putative class action complaints have been consolidated in the SDNY. In the consolidated SDNY class action, certain of the plaintiffs’ claims were dismissed in November 2020 and defendants’ motion for partial dismissal of the amended consolidated complaint was granted in part and denied in part in June 2022. In the California action, the plaintiffs’ claims were dismissed in June 2021. The plaintiffs have appealed the dismissal. Odd-lot corporate bonds antitrust class action In 2020, BCI, together with other financial institutions, were named as defendants in a putative class action. The complaint alleges a conspiracy to boycott developing electronic trading platforms for odd-lots and price fixing. The plaintiffs demand unspecified money damages. The defendants’ motion to dismiss was granted in 2021 and the plaintiffs have appealed the dismissal. The district court subsequently informed the parties of a potential conflict and the case was reassigned to a new district court judge. The plaintiffs have filed a motion seeking a ruling that would vacate the dismissal and allow the plaintiffs to file an amended complaint if the appeals court remands the case for further proceedings. Interest rate swap and credit default swap US civil actions Barclays PLC, Barclays Bank PLC and BCI, together with other financial institutions that act as market makers for interest rate swaps (IRS) are named as defendants in several antitrust class actions which were consolidated in the SDNY in 2016. The complaints allege the defendants conspired to prevent the development of exchanges for IRS and demand unspecified money damages. In 2018, trueEX LLC filed an antitrust class action in the SDNY against a number of financial institutions including Barclays PLC, Barclays Bank PLC and BCI based on similar allegations with respect to trueEX LLC’s development of an IRS platform. In 2017, Tera Group Inc. filed a separate civil antitrust action in the SDNY claiming that certain conduct alleged in the IRS cases also caused the plaintiff to suffer harm with respect to the Credit Default Swaps market. In 2018 and 2019, respectively, the court dismissed certain claims in both cases for unjust enrichment and tortious interference but denied motions to dismiss the federal and state antitrust claims, which remain pending. BDC Finance L.L.C. In 2008, BDC Finance L.L.C. (BDC) filed a complaint in the Supreme Court of the State of New York (NY Supreme Court), demanding damages of $298m, alleging that Barclays Bank PLC had breached a contract in connection with a portfolio of total return swaps governed by an ISDA Master Agreement (the Master Agreement). Following a trial, the court ruled in 2018 that Barclays Bank PLC was not a defaulting party, which was affirmed on appeal. In April 2021, the trial court entered judgement in favour of Barclays Bank PLC for $3.3m and as yet to be determined legal fees and costs. BDC appealed. In January 2022, the appellate court reversed the trial court’s summary judgment decision in favour of Barclays Bank PLC and remanded the case to the lower court for further proceedings, with the trial scheduled to commence in the fourth quarter of 2022. In 2011, BDC’s investment advisor, BDCM Fund Adviser, L.L.C. and its parent company, Black Diamond Capital Holdings, L.L.C. also sued Barclays Bank PLC and BCI in Connecticut State Court for unspecified damages allegedly resulting from Barclays Bank PLC’s conduct relating to the Master Agreement, asserting claims for violation of the Connecticut Unfair Trade Practices Act and tortious interference with business and prospective business relations. This case is currently stayed. Civil actions in respect of the US Anti-Terrorism Act There are a number of civil actions, on behalf of more than 4,000 plaintiffs, filed in US federal courts in the US District Court in the Eastern District of New York (EDNY) and SDNY against Barclays Bank PLC and a number of other banks. The complaints generally allege that Barclays Bank PLC and those banks engaged in a conspiracy to facilitate US dollar-denominated transactions for the Iranian Government and various Iranian banks, which in turn funded acts of terrorism that injured or killed the plaintiffs or the plaintiffs’ family members. The plaintiffs seek to recover damages for pain, suffering and mental anguish under the provisions of the US Anti-Terrorism Act, which allow for the trebling of any proven damages. The court granted the defendants’ motions to dismiss three out of the six actions in the EDNY. The plaintiffs have appealed in one action. The remaining actions are stayed pending a decision on the appeal. Out of the two actions in the SDNY, the court also granted the defendants’ motion to dismiss the first action which is stayed pending a decision on the EDNY appeal. The second SDNY action is stayed pending any appeal on the dismissal of the first. Shareholder derivative action In November 2020, a purported Barclays shareholder filed a putative derivative action in New York state court against BCI and a number of current and former members of the Board of Directors of Barclays PLC and senior executives or employees of the Barclays Bank Group. The shareholder filed the claim on behalf of nominal defendant Barclays PLC, alleging that the individual defendants harmed the company through breaches of their duties, including under the Companies Act 2006. The plaintiff seeks damages on behalf of Barclays PLC for the losses that Barclays PLC allegedly suffered as a result of these alleged breaches. An amended complaint was filed in April 2021, which BCI and certain other defendants moved to dismiss. The motion to dismiss was granted in April 2022. The plaintiffs are appealing the decision. Derivative transactions civil action In 2021, Vestia (a Dutch housing association) brought a claim against Barclays Bank PLC in the UK in the High Court in relation to a series of derivative transactions entered into with Barclays Bank PLC between 2008 and 2011, seeking damages of £329m. Barclays Bank PLC is defending the claim and has made a counterclaim. Timeshare loans, skilled person review and associated matters In August 2020, the FCA granted an application by Clydesdale Financial Services Limited (CFS), which trades as Barclays Partner Finance and houses Barclays’ point-of-sale finance business, for a validation order with respect to certain loans to customers brokered between April 2014 and April 2016 by Azure Services Limited (ASL), a timeshare operator, which did not, at the point of sale, hold the necessary broker licence. As a condition to the validation order, the FCA required CFS to undertake a skilled person review of the assessment of affordability processes for the loans brokered by ASL (ASL Loans) as well as CFS’ policies and procedures for assessing affordability and oversight of brokers more generally, and dictated a remediation methodology in the event that ASL Loans did not pass the affordability test. CFS voluntarily agreed to remediate the ASL Loans, in accordance with the FCA’s methodology and the remediation exercise is substantively complete. The remaining scope of the skilled person review is also complete. The skilled person made a number of observations, some of which were adverse, about both current and historic affordability practices as well as current oversight practices. CFS is not required to conduct a full back book review but, following a review of certain cohorts of loans to determine historic affordability and/or broker oversight practices that may have caused customer harm, where harm is identified, CFS’ intention is to remediate. To date CFS has identified a number of areas for remediation but the scoping exercise is ongoing. Separately, and notwithstanding this, CFS decided in March 2022 to extend the proactive remediation of ASL Loans beyond those brokered between April 2014 to April 2016 to include the full portfolio of ASL Loans brokered between 2006 and 2018. In the first quarter of 2022, a customer remediation provision of £181m has been recognised in relation to the remediation of the ASL Loans originated outside the April 2014 to April 2016 period. This provision represents the best estimate as at 30 June 2022. CFS continues to review complaints about other legacy partner finance loans, however, it is not currently possible to predict the outcome of this review or the financial impact on the Barclays Bank Group. Over-issuance of securities in the US Barclays Bank PLC maintains a US shelf registration statement with the Securities and Exchange Commission (SEC) in order to issue securities to US investors. In May 2017, Barclays Bank PLC was the subject of an SEC settlement order as a result of which it lost its status as a “well-known seasoned issuer” (or WKSI) and was required to register a specified amount of securities to be issued under any US shelf registration statements filed with the SEC. On 10 March 2022, executive management became aware that Barclays Bank PLC had issued securities materially in excess of the set amount under its 2019 US shelf registration statement (2019 F-3) and subsequently became aware that securities had also been issued in excess of the set amount under the predecessor US shelf registration statement (the Predecessor Shelf). The securities that have been over-issued comprise structured notes and exchange traded notes (ETNs). Securities issued in excess of the amount registered are considered to be “unregistered securities” for the purposes of US securities laws with certain purchasers of those securities having a right to recover, upon the tender of such security to, Barclays Bank PLC, the consideration paid for such security with interest, less the amount of any income received, or to recover damages from Barclays Bank PLC if the purchaser no longer owns the security and had sold the security at a loss (the Rescission Price). Barclays Bank PLC is expected to launch a rescission offer on 1 August 2022, by which Barclays Bank PLC will offer to repurchase the relevant affected securities for the rescission price (the Rescission Offer). Although the Rescission Offer is expected to reduce liability with respect to potential private civil claims, it will not necessarily prevent such claims from being asserted against Barclays Bank PLC and/or its affiliates, including claims under applicable US federal securities laws. Further, the Rescission Offer does not bar the SEC and other regulators from pursuing enforcement actions against Barclays Bank PLC and its affiliates, which are expected to result in fines, penalties and/or other sanctions. The Barclays Bank Group is engaged with, and responding to inquiries and requests for information from, various regulators, including the SEC. The SEC’s investigation into this matter is at an advanced stage and the Barclays Bank Group has had preliminary discussions with the staff of the SEC’s Division of Enforcement about resolving this matter. As at 30 June 2022, Barclays Bank PLC has recognised a balance sheet provision of £1,757m (December 2021: £220m) in relation to this matter, out of which £1,592m (December 2021: £220m) relates to the over-issuance of structured notes and £165m (December 2021: £nil) relates to liabilities that could be incurred arising out of ongoing discussions in respect of a potential SEC resolution. A contingent liability exists in relation to the over-issuance of ETNs due to evidentiary challenges and the high level of trading in the securities. A contingent liability also exists in relation to any potential civil claims or enforcement actions taken against Barclays Bank PLC and/or its affiliates, but Barclays Bank PLC is unable to assess the likelihood of liabilities that may arise out of such claims or actions. Any liabilities, claims or actions in connection with the over-issuance of securities under its 2019 F-3 and the Predecessor Shelf could have an adverse effect on Barclays Bank PLC’s and the Barclays Bank Group’s business, financial condition, results of operations and reputation as a frequent issuer in the securities markets. Investigation into the use of unapproved communications platforms In July 2022, Barclays Bank PLC and BCI reached an agreement in principle with the staff of the SEC’s Division of Enforcement and the staff of the Commodity Futures Trading Commission (CFTC) in connection with investigations by the SEC and the CFTC of Barclays Bank PLC, BCI and other financial institutions as part of a financial industry sweep regarding compliance with record-keeping obligations in connection with business-related communications sent over unapproved electronic messaging platforms. The SEC and the CFTC found that Barclays Bank PLC and BCI failed to comply with their respective record keeping rules, where such communications were sent or received by employees over electronic messaging channels that had not been approved by the bank for business use by employees. The proposed resolutions will include Barclays Bank PLC and BCI paying a combined $125m civil monetary penalty to the SEC and a $75m civil monetary penalty to the CFTC. There will also be non-financial components to the settlements which have yet to be finalised and agreed with the SEC and CFTC. Subject to final agreement of the terms of the settlements and related documentation, as well as the SEC’s and CFTC’s approval, the civil monetary penalties are expected to be paid during the third quarter of 2022. HM Revenue & Customs (HMRC) assessments concerning UK Value Added Tax In 2018, HMRC issued notices that have the effect of removing certain overseas subsidiaries that have operations in the UK from Barclays’ UK VAT group, in which group supplies between members are generally free from VAT. The notices have retrospective effect and correspond to assessments of £181m (inclusive of interest), of which Barclays would expect to attribute an amount of approximately £128m to Barclays Bank UK PLC and £53m to Barclays Bank PLC. HMRC’s decision has been appealed to the First Tier Tribunal (Tax Chamber). Local authority civil actions concerning LIBOR Following settlement by Barclays Bank PLC of various governmental investigations concerning certain benchmark interest rate submissions referred to above in ‘Investigations into LIBOR and other benchmarks and related civil actions’, in the UK, certain local authorities brought claims in 2018 against Barclays Bank PLC and Barclays Bank UK PLC asserting that they entered into loans between 2006 and 2008 in reliance on misrepresentations made by Barclays Bank PLC in respect of its conduct in relation to LIBOR. Barclays Bank PLC and Barclays Bank UK PLC were successful in their applications to strike out the claims. The claims have been settled on terms such that the parties have agreed not to pursue these claims further and to bear their own costs. The financial impact of the settlements is not material to the Barclays Bank Group’s operating results, cash flows or financial position. General The Barclays Bank Group is engaged in various other legal, competition and regulatory matters in the UK, the US and a number of other overseas jurisdictions. It is subject to legal

Interest rate benchmark reform [Abstract]
Interest rate benchmark reform	Interest rate benchmark reform Following the financial crisis, the reform and replacement of benchmark interest rates such as LIBOR became a priority for global regulators. The FCA and other global regulators instructed market participants to prepare for the cessation of GBP, EUR, CHF, JPY LIBOR and the 1-week and 2-month USD settings of LIBOR after the end of 2021. The remaining USD LIBOR settings are scheduled to cease immediately after 30 June 2023. How the Barclays Group is managing the transition to alternative benchmark rates Barclays established a Group-wide LIBOR Transition Programme, further detail on the transition programme is available in the Barclays Bank PLC Annual Report 2021. This Programme oversaw transition for GBP, EUR, CHF and JPY LIBOR exposures and continues to work to transition the remaining residual of unremediated exposures from synthetic rates, in addition to overseeing USD LIBOR transition in preparation for the 30 June 2023 cessation. The majority of GBP, EUR, CHF and JPY exposures have now transitioned from LIBOR and good progress has been made with the unremediated exposures reported at year-end 2021. A small residual population of GBP, EUR and JPY contracts remain unremediated at the end of H1 2022. The majority of these have now reset onto GBP and JPY Synthetic LIBOR rates. We continue to work with clients to bilaterally transition these trades and have raised potential risks regarding note holder consent for securitised products and Local Authority consent for Public Finance Initiative (PFI) loan deals with our regulators. The Barclays Group-wide LIBOR Transition Programme has also commenced focus on the transition of USD LIBOR exposures impacted by the 30 June 2023 cessation timeline. As with GBP, EUR, CHF and JPY LIBOR, USD LIBOR transition approaches will vary by product and nature of counterparty. H122 saw focused efforts to transition uncommitted lending exposure with further wide scale client engagement for other products due to commence in H222. Both active conversion of exposures and inclusion of fallback provisions will be leveraged for bilateral derivative and non-derivatives products. For cleared derivatives, Barclays is working with central clearing counterparties (CCPs) on transition which is expected to follow a market wide, standardised approach to reform similar to the CCP-led conversions in 2021. The Barclays Bank Group met the Q121 Federal Reserve Bank of New York milestone to cease new use of US dollar LIBOR, with limited exceptions. The Barclays Bank Group has put in place controls so that any exceptions or exemptions are approved.

Barclays Bank Group has corrected the presentation of the scheme fees incurred when Barclays acts as an “acquirer” as part of the payment transaction cycle. From 2022 onwards, the scheme fees reported under "Consumer, Cards and Payments" are presented within fees and commission income under “Transactional” fee type, which had previously been recognised in fees and commission expense. The reclassification into Fee and Commission income is a reduction of £94m for H122. The comparatives have not been restated as the effect is not considered material although the effect would have been a reduction of H121: £81m with no impact on Net fee and commission income. There is no impact on Net assets or Cash flows reported.

Analysis of movements in Level 3 assets and liabilities	Level 3 movement analysis The following table summarises the movements in the balances of Level 3 assets and liabilities during the period. The table shows gains and losses and includes amounts for all financial assets and liabilities that are held at fair value transferred to and from Level 3 during the period. Transfers have been reflected as if they had taken place at the beginning of the period. Asset and liability moves between Level 2 and Level 3 are primarily due to i) an increase or decrease in observable market activity related to an input or ii) a change in the significance of the unobservable input, with assets and liabilities classified as Level 3 if an unobservable input is deemed significant.
