Significant Accounting Policies | Significant Accounting Policies Nature of Operations. Cullen/Frost Bankers, Inc. (“Cullen/Frost”) is a financial holding company and a bank holding company headquartered in San Antonio, Texas that provides, through its subsidiaries, a broad array of products and services throughout numerous Texas markets. The terms “Cullen/Frost,” “the Corporation,” “we,” “us” and “our” mean Cullen/Frost Bankers, Inc. and its subsidiaries, when appropriate. In addition to general commercial and consumer banking, other products and services offered include trust and investment management, insurance, brokerage, mutual funds, leasing, treasury management, capital markets advisory and item processing. Basis of Presentation. The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of Cullen/Frost and all other entities in which Cullen/Frost has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies we follow conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry. The consolidated financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but in the opinion of management, reflect all adjustments necessary for a fair presentation of our financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2021, included in our Annual Report on Form 10-K filed with the SEC on February 4, 2022 (the “2021 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. Use of Estimates . The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses and the fair values of financial instruments and the status of contingencies are particularly subject to change. Cash Flow Reporting . Additional cash flow information was as follows: Six Months Ended 2022 2021 Cash paid for interest $ 22,551 $ 15,936 Cash paid for income taxes 45,500 15,400 Significant non-cash transactions: Unsettled securities transactions 110,623 358,752 Loans foreclosed and transferred to other real estate owned and foreclosed assets — 3,251 Right-of-use lease assets obtained in exchange for lessee operating lease liabilities 8,857 1,552 Treasury stock issued to 401(k) stock purchase plan — 1,749 |

The carrying value of held-to-maturity securities pledged to secure public funds, trust deposits, repurchase agreements and for other purposes, as required or permitted by law was $245.5 million and $642.3 million at June 30, 2022 and December 31, 2021, respectively. Accrued interest receivable on held-to-maturity securities totaled $18.0 million and $18.4 million at June 30, 2022 and December 31, 2021, respectively and is included in accrued interest receivable and other assets in the accompanying consolidated balance sheets. From time to time, we have reclassified certain securities from available for sale to held to maturity. The net unamortized, unrealized gain remaining on transferred securities included in accumulated other comprehensive income in the accompanying balance sheet totaled $2.1 million ($1.7 million, net of tax) at June 30, 2022 and $2.5 million ($2.0 million, net of tax) at December 31, 2021. This amount will be amortized out of accumulated other comprehensive income over the remaining life of the underlying securities as an adjustment of the yield on those securities.

At June 30, 2022, all of the securities in our available for sale municipal bond portfolio were issued by the State of Texas or political subdivisions or agencies within the State of Texas, of which approximately 75.3% are either guaranteed by the PSF or have been pre-refunded. Securities with limited marketability, such as stock in the Federal Reserve Bank and the Federal Home Loan Bank, are carried at cost and are reported as other available for sale securities in the table above. The carrying value of available-for-sale securities pledged to secure public funds, trust deposits, repurchase agreements and for other purposes, as required or permitted by law was $4.4 billion and $5.8 billion at June 30, 2022 and December 31, 2021, respectively. Accrued interest receivable on available-for-sale securities totaled $131.3 million and $120.5 million at June 30, 2022 and December 31, 2021, respectively, and is included in accrued interest receivable and other assets in the accompanying consolidated balance sheets. The table below summarizes, as of June 30, 2022, securities available for sale in an unrealized loss position for which an allowance for credit losses has not been recorded, aggregated by type of security and length of time in a continuous unrealized loss position.

This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available for sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, management does not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Contractual Maturities. The following table summarizes the maturity distribution schedule of securities held to maturity and securities available for sale as of June 30, 2022. Mortgage-backed securities are included in maturity categories based on their stated maturity date. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Other securities classified as available for sale include stock in the Federal Reserve Bank and the Federal Home Loan Bank, which have no maturity date. These securities have been included in the total column only.

Most of our lending activity occurs within the State of Texas, including the four largest metropolitan areas of Austin, Dallas/Ft. Worth, Houston and San Antonio, as well as other markets. The majority of our loan portfolio consists of commercial and industrial and commercial real estate loans. As of June 30, 2022, there were no concentrations of loans related to any single industry in excess of 10% of total loans. The largest industry concentration was related to the energy industry, which totaled 5.9% of total loans (also 5.9% excluding PPP loans). Unfunded commitments to extend credit and standby letters of credit issued to customers in the energy industry totaled $887.3 million and $79.1 million, respectively, as of June 30, 2022. Foreign Loans. We have U.S. dollar denominated loans and commitments to borrowers in Mexico. The outstanding balance of these loans and the unfunded amounts available under these commitments were not significant at June 30, 2022 or December 31, 2021. Related Party Loans . In the ordinary course of business, we have granted loans to certain directors, executive officers and their affiliates (collectively referred to as “related parties”). Such loans totaled $342.5 million at June 30, 2022 and $350.5 million at December 31, 2021. Accrued Interest Receivable. Accrued interest receivable on loans totaled $44.8 million and $40.0 million at June 30, 2022 and December 31, 2021, respectively and is included in accrued interest receivable and other assets in the accompany consolidated balance sheets. Non-Accrual and Past Due Loans. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Non-accrual loans, segregated by class of loans, were as follows: June 30, 2022 December 31, 2021 Total Non-Accrual Non-Accrual with No Credit Loss Allowance Total Non-Accrual Non-Accrual with No Credit Loss Allowance Commercial and industrial $ 11,170 $ 3,093 $ 22,582 $ 4,701 Energy 11,114 6,442 14,433 8,533 Paycheck Protection Program — — — — Commercial real estate: Buildings, land and other 11,806 6,419 15,297 13,817 Construction — — 948 — Consumer real estate 1,035 732 440 138 Consumer and other — — 13 13 Total $ 35,125 $ 16,686 $ 53,713 $ 27,202 The following table presents non-accrual loans as of June 30, 2022 by class and year of origination. 2022 2021 2020 2019 2018 Prior Revolving Loans Revolving Loans Converted to Term Total Commercial and industrial $ — $ 98 $ 3,520 $ 3,507 $ 1,491 $ 653 $ 108 $ 1,793 $ 11,170 Energy 5,779 — — — 21 — 5,127 187 11,114 Paycheck Protection Program — — — — — — — — — Commercial real estate: Buildings, land and other 1,116 7,556 — 229 313 2,592 — — 11,806 Construction — — — — — — — — — Consumer real estate — — — — — 380 — 655 1,035 Consumer and other — — — — — — — — — Total $ 6,895 $ 7,654 $ 3,520 $ 3,736 $ 1,825 $ 3,625 $ 5,235 $ 2,635 $ 35,125 Had non-accrual loans performed in accordance with their original contract terms, we would have recognized additional interest income, net of tax, of approximately $436 thousand and $843 thousand for the three and six months ended June 30, 2022, respectively, and approximately $427 thousand and $881 thousand for the three and six months ended June 30, 2021, respectively.

The modifications during the reported periods did not significantly impact our determination of the allowance for credit losses on loans. Information as of or for the six months ended June 30, 2022 and 2021 related to loans restructured during the preceding twelve months is set forth in the following table.

As part of the on-going monitoring of the credit quality of our loan portfolio, management tracks certain credit quality indicators including trends related to (i) the weighted-average risk grade of commercial loans, (ii) the level of classified commercial loans, (iii) the delinquency status of consumer loans, (iv) non-performing loans (see details above) and (v) the general economic conditions in the State of Texas. We utilize a risk grading matrix to assign a risk grade to each of our commercial loans. Loans are graded on a scale of 1 to 14. A description of the general characteristics of the 14 risk grades is set forth in our 2021 Form 10-K. We monitor portfolio credit quality by the weighted-average risk grade of each class of commercial loan. Individual relationship managers, under the oversight of credit administration, review updated financial information for all pass grade loans to reassess the risk grade on at least an annual basis. When a loan has a risk grade of 9, it is still considered a pass grade loan; however, it is considered to be on management’s “watch list,” where a significant risk-modifying action is anticipated in the near term. When a loan has a risk grade of 10 or higher, a special assets officer monitors the loan on an on-going basis. The following tables present weighted-average risk grades for all commercial loans, by class and year of origination/renewal as of June 30, 2022. Paycheck Protection Program (“PPP”) loans are excluded as such loans are fully guaranteed by the Small Business Administration (“SBA”). 2022 2021 2020 2019 2018 Prior Revolving Loans Revolving Loans Converted to Term Total W/A Risk Grade Commercial and industrial Risk grades 1-8 $ 1,009,520 $ 805,675 $ 563,122 $ 267,129 $ 142,114 $ 221,192 $ 2,213,761 $ 54,235 $ 5,276,748 6.23 Risk grade 9 12,633 21,474 6,914 9,067 20,961 8,682 79,546 5,662 164,939 9.00 Risk grade 10 5,000 23,293 2,437 705 1,808 255 20,879 2,093 56,470 10.00 Risk grade 11 — 1,651 6,280 9,490 1,556 2,027 4,100 4,846 29,950 11.00 Risk grade 12 — 98 2,569 3,106 1,427 251 108 747 8,306 12.00 Risk grade 13 — — 951 401 64 402 — 1,046 2,864 13.00 $ 1,027,153 $ 852,191 $ 582,273 $ 289,898 $ 167,930 $ 232,809 $ 2,318,394 $ 68,629 $ 5,539,277 6.38 W/A risk grade 6.28 7.03 6.10 6.75 7.01 5.79 6.20 7.52 6.38 Energy Risk grades 1-8 $ 312,271 $ 111,163 $ 6,939 $ 6,332 $ 3,564 $ 5,239 $ 446,460 $ 49,185 $ 941,153 5.57 Risk grade 9 1,660 95 268 1,192 26 — 10,955 39 14,235 9.00 Risk grade 10 — — 73 515 239 — — 58 885 10.00 Risk grade 11 9,097 221 541 4,630 885 164 5,000 — 20,538 11.00 Risk grade 12 3,463 — — — 21 — 2,771 187 6,442 12.00 Risk grade 13 2,316 — — — — — 2,356 — 4,672 13.00 $ 328,807 $ 111,479 $ 7,821 $ 12,669 $ 4,735 $ 5,403 $ 467,542 $ 49,469 $ 987,925 5.82 W/A risk grade 6.09 5.66 7.69 8.63 8.30 7.17 5.46 6.25 5.82 Commercial real estate: Buildings, land, other Risk grades 1-8 $ 1,101,851 $ 1,495,414 $ 999,836 $ 788,421 $ 428,539 $ 963,918 $ 84,964 $ 106,450 $ 5,969,393 6.90 Risk grade 9 64,026 27,271 99,934 47,898 20,773 35,908 7,412 2,848 306,070 9.00 Risk grade 10 5,851 17,824 17,104 52,210 20,353 53,622 3,500 — 170,464 10.00 Risk grade 11 162 434 1,269 7,189 8,969 44,318 206 — 62,547 11.00 Risk grade 12 646 6,545 — 229 313 2,592 — — 10,325 12.00 Risk grade 13 470 1,011 — — — — — — 1,481 13.00 $ 1,173,006 $ 1,548,499 $ 1,118,143 $ 895,947 $ 478,947 $ 1,100,358 $ 96,082 $ 109,298 $ 6,520,280 7.12 W/A risk grade 7.01 7.23 7.16 7.25 7.28 6.95 7.24 6.44 7.12 Construction Risk grades 1-8 $ 276,072 $ 662,364 $ 179,896 $ 100,915 $ 631 $ 1,804 $ 253,781 $ 4,247 $ 1,479,710 6.86 Risk grade 9 11,295 637 2,670 — — 401 — — 15,003 9.00 Risk grade 10 27,992 — — 13,103 — — — — 41,095 10.00 Risk grade 11 — — — — — — — — — 11.00 Risk grade 12 — — — — — — — — — 12.00 Risk grade 13 — — — — — — — — — 13.00 $ 315,359 $ 663,001 $ 182,566 $ 114,018 $ 631 $ 2,205 $ 253,781 $ 4,247 $ 1,535,808 6.96 W/A risk grade 7.10 7.12 6.64 8.21 6.21 7.16 6.10 5.01 6.96 Total commercial real estate $ 1,488,365 $ 2,211,500 $ 1,300,709 $ 1,009,965 $ 479,578 $ 1,102,563 $ 349,863 $ 113,545 $ 8,056,088 7.09 W/A risk grade 7.03 7.19 7.09 7.36 7.28 6.95 6.41 6.39 7.09 In the table above, certain energy and commercial real estate loans are reported as 2022 originations and have risk grades of 11 or higher.

The TLI, the components of which are more fully described in our 2021 Form 10-K, totaled 138.4 at June 30, 2022 and 135.9 at December 31, 2021. A higher TLI value implies more favorable economic conditions. Allowance For Credit Losses - Loans. The allowance for credit losses on loans is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. The amount of the allowance represents management's best estimate of current expected credit losses on loans considering available information, from internal and external sources, relevant to assessing collectibility over the loans' contractual terms, adjusted for expected prepayments when appropriate. Credit loss expense related to loans reflects the totality of actions taken on all loans for a particular period including any necessary increases or decreases in the allowance related to changes in credit loss expectations associated with specific loans or pools of loans. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While management utilizes its best judgment and information available, the ultimate appropriateness of the allowance is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. Our allowance methodology is more fully described in our 2021 Form 10-K. The following table presents details of the allowance for credit losses on loans segregated by loan portfolio segment as of June 30, 2022 and December 31, 2021. No allowance for credit losses has been recognized for PPP loans as such loans are fully guaranteed by the SBA.

Commitments Contingencies and Guarantees | Off-Balance-Sheet Arrangements, Commitments, Guarantees and Contingencies Financial Instruments with Off-Balance-Sheet Risk . In the normal course of business, we enter into various transactions, which, in accordance with generally accepted accounting principles are not included in our consolidated balance sheets. We enter into these transactions to meet the financing needs of our customers. As more fully discussed in our 2021 Form 10-K, these transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. We minimize our exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. Financial instruments with off-balance-sheet risk were as follows: June 30, December 31, Commitments to extend credit $ 10,771,940 $ 10,420,142 Standby letters of credit 327,847 238,690 Deferred standby letter of credit fees 1,890 2,072 Allowance For Credit Losses - Off-Balance-Sheet Credit Exposures. The allowance for credit losses on off-balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. Off-balance-sheet credit exposures primarily consist of amounts available under outstanding lines of credit and letters of credit detailed in the table above. The amount of the allowance represents management's best estimate of expected credit losses on commitments expected to be funded over the contractual life of the commitment. Our allowance methodology is more fully described in our 2021 Form 10-K. The following table details activity in the allowance for credit losses on off-balance-sheet credit exposures.

Banking Regulation, Common Equity Tier One Risk-Based Capital [Abstract] | |
Capital and Regulatory Matters | Capital and Regulatory Matters Banks and bank holding companies are subject to various regulatory capital requirements administered by state and 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. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors. Cullen/Frost’s and Frost Bank’s Common Equity Tier 1 capital (“CET1”) includes common stock and related paid-in capital, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in CET1. We also elected to exclude the effects of credit loss accounting under CECL from CET1 for a five-year transitional period, as further discussed in our 2021 Form 10-K. This CECL transitional adjustment totaled $46.2 million and $61.6 million at June 30, 2022 and December 31, 2021, respectively. CET1 is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities. Frost Bank's CET1 is also reduced by its equity investment in its financial subsidiary, Frost Insurance Agency (“FIA”). Tier 1 capital includes CET1 and additional Tier 1 capital. For Cullen/Frost, additional Tier 1 capital included $145.5 million of 4.450% non-cumulative perpetual preferred stock at June 30, 2022 and December 31, 2021, the details of which are further discussed below. Frost Bank did not have any additional Tier 1 capital beyond Common Equity Tier 1 at June 30, 2022 or December 31, 2021. Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital for both Cullen/Frost and Frost Bank includes a permissible portion of the allowances for credit losses on securities, loans and off-balance-sheet credit exposures. Tier 2 capital for Cullen/Frost also includes the permissible portion of qualified subordinated debt (which decreases 20.0% per year during the final five years of the term of the notes) totaling $80.0 million at June 30, 2022 and $100.0 million at December 31, 2021 and trust preferred securities totaling $120.0 million at both June 30, 2022 and December 31, 2021. The following table presents actual and required capital ratios as of June 30, 2022 and December 31, 2021 for Cullen/Frost and Frost Bank under the Basel III Capital Rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. See the 2021 Form 10-K for a more detailed discussion of the Basel III Capital Rules.

Based on the ratios presented above, capital levels as of June 30, 2022 at Cullen/Frost and Frost Bank exceed the minimum levels necessary to be considered “well capitalized.” Cullen/Frost and Frost Bank are subject to the regulatory capital requirements administered by the Federal Reserve Board and, for Frost Bank, the Federal Deposit Insurance Corporation (“FDIC”). Regulatory authorities can initiate certain mandatory actions if Cullen/Frost or Frost Bank fail to meet the minimum capital requirements, which could have a direct material effect on our financial statements. Management believes, as of June 30, 2022, that Cullen/Frost and Frost Bank meet all capital adequacy requirements to which they are subject. Preferred Stock. Outstanding preferred stock includes 150,000 shares, or $150.0 million in aggregate liquidation preference, of our 4.450% Non-Cumulative Perpetual Preferred Stock, Series B, par value $0.01 and liquidation preference $1,000 per share (“Series B Preferred Stock”). Each share of Series B Preferred Stock issued and outstanding is represented by 40 depositary shares, each representing a 1/40th ownership interest in a share of the Series B Preferred Stock (equivalent to a liquidation preference of $25 per share). The Series B Preferred Stock qualifies as Tier 1 capital for the purposes of the regulatory capital calculations. The net proceeds from the issuance and sale of the Series B Preferred Stock, after deducting $4.5 million of issuance costs including the underwriting discount and professional service fees, among other things, were approximately $145.5 million. Refer to our 2021 Form 10-K for additional details related to our Series B Preferred Stock. Stock Repurchase Plans. From time to time, our board of directors has authorized stock repurchase plans. In general, stock repurchase plans allow us to proactively manage our capital position and return excess capital to shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy obligations related to stock compensation awards. On January 26, 2022, our board of directors authorized a $100.0 million stock repurchase program, allowing us to repurchase shares of our common stock over a one through private transactions. No shares have been repurchased under this plan or the prior plan during the reported periods. Under the Basel III Capital Rules, Cullen/Frost may not repurchase or redeem any of its preferred stock or subordinated notes and, in some cases, its common stock without the prior approval of the Federal Reserve Board. Dividend Restrictions . In the ordinary course of business, Cullen/Frost is dependent upon dividends from Frost Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements, including to repurchase its common stock. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of Frost Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years. Under the foregoing dividend restrictions and while maintaining its “well capitalized” status, at June 30, 2022, Frost Bank could pay aggregate dividends of up to $447.3 million to Cullen/Frost without prior regulatory approval. Under the terms of the junior subordinated deferrable interest debentures that Cullen/Frost has issued to Cullen/Frost Capital Trust II, Cullen/Frost has the right at any time during the term of the debentures to defer the payment of interest at any time or from time to time for an extension period not exceeding 20 consecutive quarterly periods with respect to each extension period. In the event that we have elected to defer interest on the debentures, we may not, with certain exceptions, declare or pay any dividends or distributions on our capital stock or purchase or acquire any of our capital stock. |

Derivative Financial Instruments | Derivative Financial Instruments The fair value of derivative positions outstanding is included in accrued interest receivable and other assets and accrued interest payable and other liabilities in the accompanying consolidated balance sheets and in the net change in each of these financial statement line items in the accompanying consolidated statements of cash flows. Interest Rate Derivatives. We utilize interest rate swaps, caps, swaptions and floors to mitigate exposure to interest rate risk and to facilitate the needs of our customers. Our objectives for utilizing these derivative instruments are described in our 2021 Form 10-K. The notional amounts and estimated fair values of interest rate derivative contracts are presented in the following table. The fair values of interest rate derivative contracts are estimated utilizing internal valuation methods with observable market data inputs, or as determined by the Chicago Mercantile Exchange (“CME”) for centrally cleared derivative contracts. CME rules legally characterize variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposure rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. Variation margin, as determined by the CME, is settled daily. As a result, derivative contracts that clear through the CME have an estimated fair value of zero as of June 30, 2022 and December 31, 2021. June 30, 2022 December 31, 2021 Notional Estimated Notional Estimated Derivatives designated as hedges of fair value: Financial institution counterparties: Loan/lease interest rate swaps – assets $ 1,743 $ 18 $ — $ — Loan/lease interest rate swaps – liabilities — — 2,426 (34) Non-hedging interest rate derivatives: Financial institution counterparties: Loan/lease interest rate swaps – assets 904,706 27,908 247,592 1,207 Loan/lease interest rate swaps – liabilities 244,663 (2,489) 928,756 (19,142) Loan/lease interest rate caps – assets 269,389 10,209 270,431 3,239 Customer counterparties: Loan/lease interest rate swaps – assets 244,663 3,350 928,756 39,864 Loan/lease interest rate swaps – liabilities 904,706 (45,542) 247,592 (2,846) Loan/lease interest rate caps – liabilities 269,389 (10,209) 270,431 (3,239) The weighted-average rates paid and received for interest rate swaps outstanding at June 30, 2022 were as follows: Weighted-Average Interest Interest Interest rate swaps: Fair value hedge loan/lease interest rate swaps 1.58 % 1.06 % Non-hedging interest rate swaps – financial institution counterparties 3.71 2.87 Non-hedging interest rate swaps – customer counterparties 2.87 3.71 The weighted-average strike rate for outstanding interest rate caps was 3.28% at June 30, 2022. Commodity Derivatives. We enter into commodity swaps and option contracts that are not designated as hedging instruments primarily to accommodate the business needs of our customers. Upon the origination of a commodity swap or option contract with a customer, we simultaneously enter into an offsetting contract with a third party financial institution to mitigate the exposure to fluctuations in commodity prices. The notional amounts and estimated fair values of non-hedging commodity swap and option derivative positions outstanding are presented in the following table. We obtain dealer quotations and use internal valuation methods with observable market data inputs to value our commodity derivative positions. June 30, 2022 December 31, 2021 Notional Notional Estimated Notional Estimated Financial institution counterparties: Oil – assets Barrels 4,173 $ 20,653 4,809 $ 14,721 Oil – liabilities Barrels 9,125 (181,161) 7,032 (73,594) Natural gas – assets MMBTUs 11,753 3,181 15,947 4,143 Natural gas – liabilities MMBTUs 21,557 (38,990) 29,446 (21,249) Customer counterparties: Oil – assets Barrels 9,606 182,274 7,046 74,437 Oil – liabilities Barrels 3,692 (20,306) 4,796 (14,294) Natural gas – assets MMBTUs 21,557 39,110 29,446 21,456 Natural gas – liabilities MMBTUs 11,753 (3,181) 15,947 (4,124) Foreign Currency Derivatives . We enter into foreign currency forward and option contracts that are not designated as hedging instruments primarily to accommodate the business needs of our customers. Upon the origination of a foreign currency denominated transaction with a customer, we simultaneously enter into an offsetting contract with a third party financial institution to negate the exposure to fluctuations in foreign currency exchange rates. We also utilize foreign currency forward contracts and options that are not designated as hedging instruments to mitigate the economic effect of fluctuations in foreign currency exchange rates on foreign currency holdings and certain short-term, non-U.S. dollar denominated loans. The notional amounts and fair values of open foreign currency forward and option contracts were as follows: June 30, 2022 December 31, 2021 Notional Notional Estimated Notional Estimated Financial institution counterparties: Forward and option contracts – assets EUR 6,400 $ 16 1,900 $ 29 Forward and option contracts – assets CAD 658 9 658 — Forward and option contracts – liabilities EUR 6,400 (174) — — Customer counterparties: Forward and option contracts – assets EUR 6,400 174 — — Forward and option contracts – assets CAD — — 658 4 Forward and option contracts – liabilities EUR 6,400 (16) 1,900 (55) Forward and option contracts – liabilities CAD 658 (5) — — Gains, Losses and Derivative Cash Flows . For fair value hedges, the changes in the fair value of both the derivative hedging instrument and the hedged item are included in other non-interest income or other non-interest expense. The extent that such changes in fair value do not offset represents hedge ineffectiveness. Net cash flows from interest rate swaps on commercial loans/leases designated as hedging instruments in effective hedges of fair value are included in interest income on loans. For non-hedging derivative instruments, gains and losses due to changes in fair value and all cash flows are included in other non-interest income and other non-interest expense. Amounts included in the consolidated statements of income related to interest rate derivatives designated as hedges of fair value were as follows: Three Months Ended Six Months Ended 2022 2021 2022 2021 Commercial loan/lease interest rate swaps: Amount of gain (loss) included in interest income on loans $ (5) $ (25) $ (18) $ (53) Amount of (gain) loss included in other non-interest expense 3 2 5 5 As stated above, we enter into non-hedge related derivative positions primarily to accommodate the business needs of our customers. Upon the origination of a derivative contract with a customer, we simultaneously enter into an offsetting derivative contract with a third party financial institution. We recognize immediate income based upon the difference in the bid/ask spread of the underlying transactions with our customers and the third party. Because we act only as an intermediary for our customer, subsequent changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact our results of operations. Amounts included in the consolidated statements of income related to non-hedge related derivative instruments are presented in the table below. Three Months Ended Six Months Ended 2022 2021 2022 2021 Non-hedging interest rate derivatives: Other non-interest income $ 515 $ 141 $ 1,031 $ 1,728 Other non-interest expense — — — (1) Non-hedging commodity derivatives: Other non-interest income 649 969 1,578 2,123 Non-hedging foreign currency derivatives: Other non-interest income 45 — 63 30 Counterparty Credit Risk. Our credit exposure relating to interest rate swaps, commodity swaps/options and foreign currency forward and option contracts with bank customers was approximately $198.1 million at June 30, 2022. This credit exposure is partly mitigated as transactions with customers are generally secured by the collateral, if any, securing the underlying transaction being hedged. Our credit exposure, net of collateral pledged, relating to interest rate swaps, commodity swaps/options and foreign currency forward/option contracts with upstream financial institution counterparties was approximately $41.5 million at June 30, 2022. This amount was primarily related to initial margin payments to the CME and excess collateral we posted to counterparties. Excess collateral is generally cleared on the next business day. Collateral levels for upstream financial institution counterparties are monitored and adjusted as necessary. See Note 9 – Balance Sheet Offsetting and Repurchase Agreements for additional information regarding our credit exposure with upstream financial institution counterparties. At June 30, 2022, we had $212.4 million in cash collateral related to derivative contracts on deposit with other financial institution counterparties. |

Balance Sheet Offsetting | Balance Sheet Offsetting and Repurchase Agreements Balance Sheet Offsetting. Certain financial instruments, including resell and repurchase agreements and derivatives, may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements or similar agreements. Our derivative transactions with upstream financial institution counterparties are generally executed under International Swaps and Derivative Association (“ISDA”) master agreements which include “right of set-off” provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, we do not generally offset such financial instruments for financial reporting purposes.

No valuation allowance for deferred tax assets was recorded at June 30, 2022 as management believes it is more likely than not that all of the deferred tax assets will be realized against deferred tax liabilities and projected future taxable income. The effective income tax rates differed from the U.S. statutory federal income tax rates of 21% during the comparable periods primarily due to the effect of tax-exempt income from loans, securities and life insurance policies and the income tax effects associated with stock-based compensation. There were no unrecognized tax benefits during any of the reported periods. Interest and/or penalties related to income taxes are reported as a component of income tax expense. Such amounts were not significant during the reported periods. We file income tax returns in the U.S. federal jurisdiction. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2018. |

Fair Value Measurements

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, we utilize valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820 establishes a three-level fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. See our 2021 Form 10-K for additional information regarding the fair value hierarchy and a description of our valuation techniques. Financial Assets and Financial Liabilities. The tables below summarize financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021, segregated by the level of the valuation inputs within the fair value hierarchy of ASC Topic 820 utilized to measure fair value.

Financial assets measured at fair value on a non-recurring basis during the reported periods include certain collateral dependent loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. The following table presents collateral dependent loans that were remeasured and reported at fair value through a specific allocation of the allowance for credit losses on loans based upon the fair value of the underlying collateral during the reported periods.

We do not have any non-financial assets or non-financial liabilities measured at fair value on a recurring basis. From time to time, non-financial assets measured at fair value on a non-recurring basis may include certain foreclosed assets which, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for loan losses and certain foreclosed assets which, subsequent to their initial recognition, were remeasured at fair value through a write-down included in other non-interest expense. There were no such fair value measurements during the reported periods. Financial Instruments Reported at Amortized Cost. The estimated fair values of financial instruments that are reported at amortized cost in our consolidated balance sheets, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value, were as follows: June 30, 2022 December 31, 2021 Carrying Estimated Carrying Estimated Financial assets: Level 2 inputs: Cash and cash equivalents $ 13,658,585 $ 13,658,585 $ 16,583,000 $ 16,583,000 Securities held to maturity 1,946,428 1,828,515 1,749,179 1,809,143 Cash surrender value of life insurance policies 189,823 189,823 190,139 190,139 Accrued interest receivable 194,049 194,049 179,111 179,111 Level 3 inputs: Loans, net 16,496,394 16,126,497 16,087,731 16,079,454 Financial liabilities: Level 2 inputs: Deposits 45,601,765 45,584,113 42,695,696 41,343,426 Federal funds purchased 43,200 43,200 25,925 25,925 Repurchase agreements 1,664,685 1,664,685 2,740,799 2,740,799 Junior subordinated deferrable interest debentures 123,040 123,712 123,011 123,712 Subordinated notes 99,256 99,626 99,178 111,430 Accrued interest payable 6,059 6,059 3,026 3,026 Under ASC Topic 825, entities may choose to measure eligible financial instruments at fair value at specified election dates.

Accounting Changes and Error Corrections [Abstract] | |
Accounting Standards Updates | Accounting Standards Updates Information about certain recently issued accounting standards updates is presented below. Also refer to Note 20 - Accounting Standards Updates in our 2021 Form 10-K for additional information related to previously issued accounting standards updates. ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method.” Under prior guidance, entities can apply the last-of-layer hedging method to hedge the exposure of a closed portfolio of prepayable financial assets to fair value changes due to changes in interest rates for a portion of the portfolio that is not expected to be affected by prepayments, defaults, and other events affecting the timing and amount of cash flows. ASU 2022-01 expands the last-of-layer method, which permits only one hedge layer, to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. ASU 2022-01 also (i) expands the scope of the portfolio layer method to include non-prepayable financial assets, (ii) specifies eligible hedging instruments in a single-layer hedge, (iii) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method and (iv) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. ASU 2022-01 will be effective for us on January 1, 2023 though early adoption is permitted. The adoption of ASU 2022-01 is not expected to have a significant impact on our financial statements. ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in Accounting Standards Codification (“ASC”) Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, ASU 2022-02 requires entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC Subtopic 3126-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. ASU 2022-02 will be effective for us on January 1, 2023 though early adoption is permitted. The adoption of ASU 2022-02 is not expected to have a significant impact on our financial statements. ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.” ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. ASU 2022-03 also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction and requires certain new disclosures for equity securities subject to contractual sale restrictions. ASU 2022-03 will be effective for us on January 1, 2024 though early adoption is permitted. The adoption of ASU 2022-03 is not expected to have a significant impact on our financial statements. |

Basis of Presentation | Basis of Presentation. The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of Cullen/Frost and all other entities in which Cullen/Frost has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies we follow conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry. The consolidated financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but in the opinion of management, reflect all adjustments necessary for a fair presentation of our financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2021, included in our Annual Report on Form 10-K filed with the SEC on February 4, 2022 (the “2021 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. |
Use of Estimates | Use of Estimates . The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses and the fair values of financial instruments and the status of contingencies are particularly subject to change. |

Accounting Policies [Abstract] | |
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance For Credit Losses - Loans. The allowance for credit losses on loans is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. The amount of the allowance represents management's best estimate of current expected credit losses on loans considering available information, from internal and external sources, relevant to assessing collectibility over the loans' contractual terms, adjusted for expected prepayments when appropriate. Credit loss expense related to loans reflects the totality of actions taken on all loans for a particular period including any necessary increases or decreases in the allowance related to changes in credit loss expectations associated with specific loans or pools of loans. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While management utilizes its best judgment and information available, the ultimate appropriateness of the allowance is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. Our allowance methodology is more fully described in our 2021 Form 10-K. |

Schedule of Notional Amounts and Estimated Fair Values of Interest Rate Derivative Contracts Outstanding | The notional amounts and estimated fair values of interest rate derivative contracts are presented in the following table. The fair values of interest rate derivative contracts are estimated utilizing internal valuation methods with observable market data inputs, or as determined by the Chicago Mercantile Exchange (“CME”) for centrally cleared derivative contracts. CME rules legally characterize variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposure rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. Variation margin, as determined by the CME, is settled daily. As a result, derivative contracts that clear through the CME have an estimated fair value of zero as of June 30, 2022 and December 31, 2021.
