Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The Consolidated Financial Statements (the “financial statements”) of Berkshire Hills Bancorp, Inc. and its subsidiaries (the “Company” or “Berkshire”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company is a Delaware corporation, headquartered in Boston, Massachusetts, and the holding company for Berkshire Bank (the “Bank”), a Massachusetts-chartered trust company headquartered in Pittsfield, Massachusetts. These financial statements include the accounts of the Company, its wholly-owned subsidiaries and the Bank’s consolidated subsidiaries. In consolidation, all significant intercompany accounts and transactions are eliminated. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless GAAP requires otherwise. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these financial statements were issued. These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and disclosures Berkshire Hills Bancorp, Inc. previously filed with the Securities and Exchange Commission in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. In management’s opinion, all adjustments necessary for a fair statement are reflected in the interim periods. Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Actual results could differ from those estimates. Recently Adopted Accounting Principles Effective January 1, 2023, the Company adopted ASU No. 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” The adoption did not have a material impact on the Company’s Consolidated Financial Statements. The ASU eliminates the troubled debt restructuring (“TDR”) accounting model that was adopted with Topic 326, “Financial Instruments – Credit Losses” and enhances disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. The ASU requires prospective disclosure of current-period gross write-offs by year of origination. Refer to Note 4 – Loans and Allowance for Credit Losses for the new financial statement disclosures applicable under this update. Future Application of Accounting Pronouncements In March 2023, the FASB issued ASU No. 2023-02, “Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force).” The guidance is intended to improve the accounting and disclosures for investments in tax credit structures. The ASU allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying investments in low-income housing tax credit structures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. The Company is still evaluating; however, the adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements.

Credit ratings express opinions about the credit quality of a security and are utilized by the Company to make informed decisions. Investment grade securities are rated BBB-/Baa3 or higher and generally considered by the rating agencies and market participants to be of low credit risk. Conversely, securities rated below investment grade are considered to have distinctively higher credit risk than investment grade securities. For securities without credit ratings, the Company utilizes other financial information indicating the financial health of the underlying municipality, agency, or organization. As of June 30, 2023, none of the Company's investment securities were delinquent or in non-accrual status. The amortized cost and estimated fair value of available for sale (“AFS”) and held to maturity (“HTM”) securities segregated by contractual maturity at June 30, 2023 are presented below. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations.

Furthermore, the Company does not intend to sell nor does it anticipate that it will be required to sell any of its securities in an unrealized loss position as of June 30, 2023, prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions as well as its historically low portfolio turnover.

Credit Loss [Abstract]
LOANS AND ALLOWANCE FOR CREDIT LOSSES	LOANS AND ALLOWANCE FOR CREDIT LOSSES The following is a summary of total loans by regulatory call report code with sub-segmentation based on underlying collateral for certain loan types: (In thousands) June 30, 2023 December 31, 2022 Construction $ 443,856 $ 319,452 Commercial multifamily 597,472 620,088 Commercial real estate owner occupied 696,771 640,489 Commercial real estate non-owner occupied 2,557,036 2,496,237 Commercial and industrial 1,438,062 1,445,236 Residential real estate 2,677,053 2,312,447 Home equity 225,434 227,450 Consumer other 246,718 273,910 Total loans $ 8,882,402 $ 8,335,309 Allowance for credit losses 100,219 96,270 Net loans $ 8,782,183 $ 8,239,039 During the three and six months ended June 30, 2023 and June 30, 2022, there were no loans reclassified to held for sale. Held for sale loans are not contained in the balances within this note and are accounted for at the lower of carrying value or fair market value within loans held for sale on the Consolidated Balance Sheet. Risk characteristics relevant to each portfolio segment are as follows: Construction - Loans in this segment primarily include real estate development loans for which payment is derived from sale of the property or long term financing at completion. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial real estate multifamily, owner occupied and non-owner - Loans in these segments are primarily owner-occupied or income-producing properties throughout New England and Northeastern New York. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy, which in turn, will have an effect on the credit quality in this segment. Management monitors the cash flows of these loans. Commercial and industrial loans - Loans in this segment are made to businesses and are generally secured by assets of the business such as accounts receivable, inventory, marketable securities, other liquid collateral, equipment and other business assets. Repayment is expected from the cash flows of the business. Loans in this segment include asset based loans which generally have no scheduled repayment and which are closely monitored against formula based collateral advance ratios. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Residential real estate - All loans in this segment are collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Home equity and other consumer loans - Loans in this segment are primarily home equity lines of credit, automobile loans and other consumer loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Allowance for Credit Losses for Loans The Allowance for Credit Losses for Loans (“ACLL”) is comprised of the allowance for loan losses, and the allowance for unfunded commitments is accounted for as a separate liability in other liabilities on the balance sheet. The level of the ACLL represents management’s estimate of expected credit losses over the expected life of the loans at the balance sheet date. The Company uses a static pool migration analysis method, applying expected historical loss trend and observed economic metrics. The level of the ACLL is based on management’s ongoing review of all relevant information, from internal and external sources, relating to past and current events, utilizing a 7 quarter reasonable and supportable forecast period with a 1 year reversion period. The ACLL reserve is overlaid with qualitative factors based upon: • the existence and growth of concentrations of credit; • the volume and severity of past due financial assets, including nonaccrual assets; • the institutions lending and credit review as well as the experience and ability of relevant management and staff and; • the effect of other external factors such as regulatory, competition, regional market conditions, legal and technological environment and other events such as natural disasters; • the effect of other economic factors such as economic stimulus and customer forbearance programs.

Loans that are given a Pass rating are not considered a problem credit. Loans that are classified as Special Mention loans are considered to have potential weaknesses and are evaluated closely by management. Substandard, including non-accruing loans, are loans for which a definitive weakness has been identified and which may make full collection of contractual cash flows questionable. Doubtful loans are those with identified weaknesses that make full collection of contractual cash flows, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. For commercial credits, the Company assigns an internal risk rating at origination and reviews the rating annual, semiannually, or quarterly depending on the risk rating. The rating is also reassessed at any point in time when management becomes aware of information that may affect the borrower’s ability to fulfill their obligations. The Company risk rates its residential mortgages, including 1-4 family and residential construction loans, based on a three rating system: Pass, Special Mention, and Substandard. Loans that are current within 59 days are rated Pass. Residential mortgages that are 60-89 days delinquent are rated Special Mention. Loans delinquent for 90 days or greater are rated Substandard and generally placed on non-accrual status.

Expected credit losses for collateral-dependent loans are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. Significant quarter over quarter changes are reflective of changes in nonaccrual status and not necessarily associated with credit quality indicators like appraisal value.

When principal forgiveness is provided, the amount of forgiveness is charged-off against the allowance for credit losses. In some cases, the Company provides multiple types of concessions on one loan. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. For the loans included in the "combination" columns below, multiple types of modifications have been made on the same loan within the current reporting period.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES As of June 30, 2023, the Company held derivatives with a total notional amount of $4.5 billion. That amount included $0.8 billion in interest rate swap derivatives that were designated as cash flow hedges for accounting purposes. The Company also had economic hedges totaling $3.7 billion and $9.4 million non-hedging derivatives, which are not designated as hedges for accounting purposes with changes in fair value recorded directly through earnings. Economic hedges included interest rate swaps totaling $3.4 billion, risk participation agreements with dealer banks of $0.3 billion, and $8.9 million in forward commitment contracts. As part of the Company’s risk management strategy, the Company enters into interest rate swap agreements to mitigate the interest rate risk inherent in certain of the Company’s assets and liabilities. Interest rate swap agreements involve the risk of dealing with both Bank customers and institutional derivative counterparties and their ability to meet contractual terms. The agreements are entered into with counterparties that meet established credit standards and contain master netting and collateral provisions protecting the at-risk party. The derivatives program is overseen by the Risk Management and Capital Committee of the Company’s Board of Directors. Based on adherence to the Company’s credit standards and the presence of the netting and collateral provisions, the Company believes that the credit risk inherent in these contracts was not significant at June 30, 2023. The Company had no pledged collateral to derivative counterparties in the form of cash as of June 30, 2023. The Company had pledged securities to derivative counterparties with an amortized cost of $10.1 million and a fair value of $9.9 million as of June 30, 2023. The Company does not typically require its commercial customers to post cash or securities as collateral on its program of back-to-back economic hedges. However certain language is written into the International Swaps Dealers Association, Inc. (“ISDA”) and loan documents where, in default situations, the Bank is allowed to access collateral supporting the loan relationship to recover any losses suffered on the derivative asset or liability. The Company may need to post additional collateral in the future in proportion to potential increases in unrealized loss positions.

Cash flow hedges The effective portion of unrealized changes in the fair value of derivatives accounted for as cash flow hedges is reported in other comprehensive income and subsequently reclassified to earnings in the same period or periods during which the hedged transaction is forecasted to affect earnings. Each quarter, the Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged item or transaction. The ineffective portion of changes in the fair value of the derivatives is recognized directly in earnings. All cash flow hedges are considered highly effective. As of June 30, 2023, the Company had eight interest rate swap contracts with a notional value of $800.0 million. The interest rate swaps have durations of two As of June 30, 2023, the Company had two interest rate collars. The first interest rate collar has a 3.00% floor and a 5.75% cap with a notional value of $100.0 million. The second interest rate collar has a 3.25% floor and a 5.75% cap with a notional value of $100.0 million. The interest rate collars have durations of three Amounts included in the Consolidated Statements of Income and in the other comprehensive income section of the Consolidated Statements of Comprehensive Income (related to interest rate derivatives designated as hedges of cash flows), were as follows: Three Months Ended Six Months Ended (In thousands) 2023 2022 2023 2022 Interest rate swaps on commercial loans: Unrealized (loss) recognized in accumulated other comprehensive loss $ (11,753) $ — $ (5,798) $ — Less: Reclassification of unrealized (loss) from accumulated other comprehensive loss to interest expense (157) — (314) — Net tax benefit on items recognized in accumulated other comprehensive income 3,197 — 1,641 — Other comprehensive loss recorded in accumulated other comprehensive income, net of reclassification adjustments and tax effects $ (8,713) $ — $ (4,471) $ — Net interest expense recognized on hedged commercial loans $ 2,034 $ — $ 3,327 $ — Economic hedges As of June 30, 2023, the Company has an interest rate swap with a $6.6 million notional amount to swap out the fixed rate of interest on an economic development bond bearing a fixed rate of 5.09%, currently within the Company’s trading portfolio under the fair value option, in exchange for a LIBOR-based floating rate. The intent of the economic hedge is to improve the Company’s asset sensitivity to changing interest rates in anticipation of favorable average floating rates of interest over the 21-year life of the bond. The fair value changes of the economic development bond are mostly offset by fair value changes of the related interest rate swap. The Company also offers certain derivative products directly to qualified commercial borrowers. The Company economically hedges derivative transactions executed with commercial borrowers by entering into mirror-image, offsetting derivatives with third-party financial institutions. The transaction allows the Company’s customer to convert a variable-rate loan to a fixed rate loan. Because the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts mostly offset each other in earnings. There was no credit valuation loss adjustment arising from the difference in credit worthiness of the commercial loan and financial institution counterparties as of June 30, 2023. The interest income and expense on these mirror image swaps exactly offset each other. The Company has risk participation agreements with dealer banks. Risk participation agreements occur when the Company participates on a loan and a swap where another bank is the lead. The Company gets paid a fee to take on the risk associated with having to make the lead bank whole on Berkshire’s portion of the pro-rated swap should the borrower default. Changes in fair value are recorded in current period earnings. The Company utilizes forward sale commitments to hedge interest rate risk and the associated effects on the fair value of interest rate lock commitments and loans originated for sale. The forward sale commitments are accounted for as derivatives with changes in fair value recorded in current period earnings. The Company uses the following types of forward sale commitments contracts: • Best efforts loan sales, • Mandatory delivery loan sales, and • To Be Announced (“TBA”) mortgage-backed securities sales. A best efforts contract refers to a loan sale agreement where the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. The Company may enter into a best efforts contract once the price is known, which is shortly after the potential borrower’s interest rate is locked. A mandatory delivery contract is a loan sale agreement where the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. Generally, the Company may enter into mandatory delivery contracts shortly after the loan closes with a customer. The Company may sell TBA mortgage-backed securities to hedge the changes in fair value of interest rate lock commitments and held for sale loans, which do not have corresponding best efforts or mandatory delivery contracts. These security sales transactions are closed once mandatory contracts are written. On the closing date the price of the security is locked-in, and the sale is paired-off with a purchase of the same security. Settlement of the security purchase/sale transaction is done with cash on a net-basis. Non-hedging derivatives The Company enters into interest rate lock commitments (“IRLCs”), or commitments to lend, for residential mortgage loans, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. IRLCs that relate to the origination of mortgage loans that will be held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding IRLCs expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The IRLCs are free-standing derivatives which are carried at fair value with changes recorded in non-interest income in the Company’s consolidated statements of operations. Changes in the fair value of IRLCs subsequent to inception are based on changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and changes in the probability that the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time.

The Company mitigates this risk by entering into equal and offsetting swap agreements with highly rated third party financial institutions. The swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated statements of condition. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral generally in the form of marketable securities is received or posted by the counterparty with net liability positions, respectively, in accordance with contract thresholds. The Company had net asset positions with its financial institution counterparties totaling $45.5 million and $51.2 million as of June 30, 2023 and December 31, 2022, respectively. The Company had net asset positions with its commercial banking counterparties totaling $2.3 million and $1.0 million as of June 30, 2023 and December 31, 2022, respectively.

Equity [Abstract]
CAPITAL RATIOS AND SHAREHOLDERS' EQUITY	CAPITAL RATIOS AND SHAREHOLDERS’ EQUITY The actual and required capital ratios were as follows: June 30, December 31, Minimum Capital Requirement Company (consolidated) Total capital to risk-weighted assets 14.4 % 14.6 % 8.0 % Common equity tier 1 capital to risk-weighted assets 12.1 12.4 4.5 Tier 1 capital to risk-weighted assets 12.3 12.6 6.0 Tier 1 capital to average assets 9.6 10.2 4.0 June 30, December 31, Regulatory Minimum to be Adequately Capitalized Regulatory Bank Total capital to risk-weighted assets 13.4 % 13.6 % 8.0 % 10.0 % Common equity tier 1 capital to risk-weighted assets 12.4 12.6 4.5 6.5 Tier 1 capital to risk-weighted assets 12.4 12.6 6.0 8.0 Tier 1 capital to average assets 9.6 10.2 4.0 5.0 The Company and the Bank are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Failure to meet capital requirements can initiate regulatory action. At each date shown, the Company met the minimum capital requirements and the Bank met the conditions to be classified as “well capitalized” under the relevant regulatory framework. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table above. As of January 1, 2019, banking organizations must maintain a minimum Common equity Tier 1 risk-based capital ratio of 7.0%, a minimum Tier 1 risk-based capital ratio of 8.5%, and a minimum Total risk-based capital ratio of 10.5%, including a 2.5% capital conservation buffer. Capital rules impose restrictions on capital distributions and certain discretionary cash bonus payments if the capital conservation buffer is not met. At June 30, 2023, the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and the Bank's regulatory capital ratios were above the minimum levels required to be considered well capitalized for regulatory purposes. The capital levels of both the Company and the Bank at June 30, 2023 also exceeded the minimum capital requirements including the currently applicable capital conservation buffer of 2.5%.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities that are carried at fair value. Recurring Fair Value Measurements The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2023 and December 31, 2022, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value.

Trading Securities at Fair Value. The Company holds one security designated as a trading security. It is a tax-advantaged economic development bond issued to the Company by a local nonprofit which provides wellness and health programs. The fair value of this security is determined based on a discounted cash flow methodology. Certain inputs to the fair value calculation are unobservable and there is little to no market activity in the security; therefore, the security meets the definition of a Level 3 security. The discount rate used in the valuation of the security is sensitive to movements in the 3-month LIBOR rate. Securities Available for Sale and Equity Securities . Equity securities classified as Level 1 consist of publicly-traded equity securities for which the fair values can be obtained through quoted market prices in active exchange markets. Equity securities classified as Level 2 consist of securities with infrequent trades in active exchange markets, and pricing is primarily sourced from third party pricing services. AFS securities classified as Level 1 consist of U.S. Treasury securities. AFS securities classified as Level 2 include most of the Company’s debt securities. The pricing on Level 2 and Level 3 was primarily sourced from third party pricing services, overseen by management, and is based on models that consider standard input factors such as dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and condition, among other things. Level 3 pricing includes inputs unobservable to market participants. Loans Held for Investment. The Company’s held for investment loan portfolio includes loans originated by Company and loans acquired through business combinations. The Company intends to hold these assets until maturity as a part of its business operations. For one acquired portfolio subset, the Company previously accounted for these purchased-credit impaired loans as a pool under ASC 310, as they were determined to have common risk characteristics. These loans were recorded at fair value on acquisition date and subsequently evaluated for impairment collectively. Upon adoption of ASC 326, the Company elected the fair value option on this portfolio, recognizing an $11.2 million fair value write-down charged to retained earnings, net of deferred tax impact, as of January 1, 2020. The fair value of this loan portfolio is determined based on a discounted cash flow methodology. Certain inputs to the fair value calculation are unobservable; therefore, the loans meet the definition of Level 3 assets. The discount rate used in the valuation is consistent with assets that have significant credit deterioration. The cash flow assumptions include payment schedules for loans with current payment histories and estimated collateral value for delinquent loans. All of these loans were nonperforming as of June 30, 2023. Aggregate Fair Value June 30, 2023 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for investment at fair value $ 401 $ 9,285 $ (8,884) Aggregate Fair Value December 31, 2022 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for investment at fair value $ 605 $ 10,948 $ (10,343) Loans Held for Sale. The Company elected the fair value option for all loans held for sale (HFS) originated for sale on or after May 1, 2012. Loans HFS are classified as Level 2 as the fair value is based on input factors such as quoted prices for similar loans in active markets. Aggregate Fair Value June 30, 2023 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for sale $ 8,708 $ 8,584 $ 124 Aggregate Fair Value December 31, 2022 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for sale $ 942 $ 927 $ 15 The changes in fair value of loans held for sale for the three and six months ended June 30, 2023, were gains of $100 thousand and $109 thousand, respectively. During the three and six months ended June 30, 2023, originations of loans held for sale totaled $22.4 million and $29.4 million, respectively. During the three and six months ended June 30, 2023, sales of loans originated for sale totaled $15.3 million and $21.7 million, respectively. The changes in fair value of loans held for sale for the three and six months ended June 30, 2022, were gains of $14 thousand and losses of $161 thousand, respectively. During the three and six months ended June 30, 2022, originations of loans held for sale totaled $2.7 million and $10.1 million, respectively. During the three and six months ended June 30, 2022, sales of loans originated for sale totaled $2.0 million and $15.1 million, respectively. Interest Rate Swaps. The valuation of the Company’s interest rate swaps is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings. Although the Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2023, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Commitments to Lend. The Company enters into commitments to lend for residential mortgage loans intended for sale, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. However, this value is adjusted by a factor which considers the likelihood that the loan in a lock position will ultimately close, and by the non-refundable costs of originating the loan. The closing ratio is derived from the Bank’s internal data and is adjusted using significant management judgment. The costs to originate are primarily based on the Company’s internal commission rates that are not observable. As such, these commitments are classified as Level 3 measurements. Forward Sale Commitments . The Company utilizes forward sale commitments as economic hedges against potential changes in the values of the commitments to lend and loans originated for sale. To Be Announced (“TBA”) mortgage-backed securities forward commitment sales are used as the hedging instrument, are classified as Level 1, and consist of publicly-traded debt securities for which identical fair values can be obtained through quoted market prices in active exchange markets. The fair values of the Company’s best efforts and mandatory delivery loan sale commitments are determined similarly to the commitments to lend using quoted prices in the market place that are observable. However, costs to originate and closing ratios included in the calculation are internally generated and are based on management’s judgment and prior experience, which are considered factors that are not observable. As such, best efforts and mandatory forward commitments are classified as Level 3 measurements. Capitalized Servicing Rights. The Company accounts for certain capitalized servicing rights at fair value in its Consolidated Financial Statements, as the Company is permitted to elect the fair value option for each specific instrument. A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. The table below presents the changes in Level 3 assets and liabilities that were measured at fair value on a recurring basis for the three and six months ended June 30, 2023 and 2022.

There were no Level 1 or Level 2 nonrecurring fair value measurements for the periods ended June 30, 2023 and December 31, 2022. Individually evaluated loans. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Non-recurring adjustments can also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for credit losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. However, the choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates, and other market factors on current values. Additionally, commercial real estate appraisals frequently involve discounting of projected cash flows, which relies inherently on unobservable data. Therefore, nonrecurring fair value measurement adjustments that relate to real estate collateral have generally been classified as Level 3. Estimates of fair value for other collateral that supports commercial loans are generally based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3. Loans Transferred to Held for Sale. Once a decision has been made to sell loans not previously classified as held for sale, these loans are transferred into the held for sale category and carried at the lower of cost or fair value. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. The choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates, and other market factors on current values. Nonrecurring fair value measurement adjustments that relate to real estate collateral have generally been classified as Level 3. Estimates of fair value for other collateral that supports commercial loans are generally based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3. Capitalized loan servicing rights . A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Adjustments are only recorded when the discounted cash flows derived from the valuation model are less than the carrying value of the asset. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. Summary of Estimated Fair Values of Financial Instruments The following tables summarize the estimated fair values (represents exit price), and related carrying amounts, of the Company’s financial instruments. Certain financial instruments and all non-financial instruments are excluded. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.

BASIS OF PRESENTATION (Policies

BASIS OF PRESENTATION (Policies)	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The Consolidated Financial Statements (the “financial statements”) of Berkshire Hills Bancorp, Inc. and its subsidiaries (the “Company” or “Berkshire”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company is a Delaware corporation, headquartered in Boston, Massachusetts, and the holding company for Berkshire Bank (the “Bank”), a Massachusetts-chartered trust company headquartered in Pittsfield, Massachusetts. These financial statements include the accounts of the Company, its wholly-owned subsidiaries and the Bank’s consolidated subsidiaries. In consolidation, all significant intercompany accounts and transactions are eliminated. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless GAAP requires otherwise. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these financial statements were issued. These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and disclosures Berkshire Hills Bancorp, Inc. previously filed with the Securities and Exchange Commission in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. In management’s opinion, all adjustments necessary for a fair statement are reflected in the interim periods.
Reclassifications	Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Actual results could differ from those estimates.
Recently Adopted Accounting Principles and Future Application of Accounting Pronouncements	Recently Adopted Accounting Principles Effective January 1, 2023, the Company adopted ASU No. 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” The adoption did not have a material impact on the Company’s Consolidated Financial Statements. The ASU eliminates the troubled debt restructuring (“TDR”) accounting model that was adopted with Topic 326, “Financial Instruments – Credit Losses” and enhances disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. The ASU requires prospective disclosure of current-period gross write-offs by year of origination. Refer to Note 4 – Loans and Allowance for Credit Losses for the new financial statement disclosures applicable under this update. Future Application of Accounting Pronouncements In March 2023, the FASB issued ASU No. 2023-02, “Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force).” The guidance is intended to improve the accounting and disclosures for investments in tax credit structures. The ASU allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying investments in low-income housing tax credit structures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. The Company is still evaluating; however, the adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements.
