PROXY STATEMENT



SOLICITATION AND REVOCATION OF PROXIES

        The accompanying proxy is solicited by the Board of Directors of International Bancshares Corporation, a Texas Corporation (the "Company") to be voted at the Annual Meeting of Shareholders to be held on May 20, 2002 at 7:00 p.m., local time, at the Laredo Country Club, 1415 Country Club Drive, Laredo, Texas. The Company will bear the cost of such solicitation. It is expected that the solicitation of proxies will be primarily by mail. Proxies may be solicited personally by regular employees of the Company at a nominal cost. Any shareholder giving a proxy has the power to revoke it at any time prior to the voting of the proxy by giving notice in person or in writing to the Secretary of the Company or by appearing at the Annual Meeting and voting in person. The approximate date on which this proxy statement and the accompanying form of proxy are first sent or given to security holders is April 15, 2002.


VOTING AT MEETING

        Only holders of record of common stock, par value $1.00 per share ("Common Stock"), of the Company at the close of business on April 4, 2002, shall be entitled to vote at the meeting. There were 25,916,586 shares of Common Stock issued and outstanding on the record date held of record by approximately 2043 shareholders. Each share of Common Stock is entitled to one vote.

        All shares entitled to vote represented by a properly executed and unrevoked proxy received in time for the meeting will be voted at the meeting in accordance with the instructions given, but in the absence of instructions to the contrary, such shares will be voted affirmatively. Persons empowered as Proxies will also be empowered to vote in their discretion upon such other matters as may properly come before the meeting or any adjournment thereof. If any nominee shall be unable to serve, which is not now contemplated, the proxies will be voted for such substitute nominee(s) as the Board of Directors recommends.

        A quorum for the transaction of business at the Annual Meeting requires representation, in person or by proxy, of the holders of a majority of the issued and outstanding shares of Common Stock. The judges of election will treat abstentions and broker non-votes as shares that are present for purposes of determining the presence of a quorum for the transaction of business at the meeting. A quorum with respect to any specific proposal to be voted on at the Annual Meeting requires representation, in person or by proxy, of the holders of a majority of the issued and outstanding shares of Common Stock entitled to vote on the proposal. Abstentions will be treated as present and entitled to vote with respect to any proposal submitted to the shareholders for a vote for purposes of determining both the presence of a quorum with respect to such proposal and the approval of such proposal. If a broker indicates on a proxy that it does not have discretionary authority as to certain shares to vote on a particular matter, the holder(s) of such shares will not be considered as present and entitled to vote with respect to such matter for purposes of determining either the presence of a quorum with respect to such matter or the approval of such matter. With respect to any proposal other than the election of directors, such proposal shall be determined by the affirmative vote of the holders of a majority of the shares of Common Stock represented, in person or by proxy, at the meeting and entitled to vote thereon. Thus, abstention with respect to any such matter will have the same legal effect as a vote against such matter, while broker non-votes will not affect the outcome of such matter. With respect to the election of directors, the directors shall be elected by a plurality vote of the holders of shares of Common Stock present at the meeting and entitled to vote thereon.

REPORT OF THE SALARY AND STEERING COMMITTEE

        The Company's compensation package for each of its executive officers consists of base salary, annual discretionary bonus and a discretionary incentive stock option grant. Also, certain executive officer(s) may receive compensation pursuant to the Company's Executive Incentive Compensation Plan. Stock option grants are determined by the Company's Compensation Committee and are discussed under the Committee's separate report below. All cash compensation paid to executive officers of the Company is paid by IBC. Base salary levels and annual bonuses are recommended by the Salary and Steering Committee of IBC (the "Committee"). The Committee during 2001 consisted of Lester Avigael, Irving Greenblum and Dennis E. Nixon.

        The Committee's recommendations regarding each executive officer's compensation is subjective with regard to both the base salary and bonus. The annual financial performance of IBC is the most important factor in the subjective analysis. The bonus program is intended to compensate each executive officer for the officer's contribution to IBC's financial performance during the previous year. At the end of each year based on the financial performance of IBC and the perceived contribution by each executive officer, a base salary recommendation for the next year and a bonus recommendation for the previous year is made for each executive officer by the Committee. The overall bonus pool for executive officers is affected by the earnings performance of IBC for the previous year. All base salary and bonus recommendations of the Committee are subject to final approval of the Board of Directors of IBC.

        With respect to the compensation of Mr. Nixon, the CEO of the Company, the Committee recommends to the Board of Directors the CEO's salary and bonus based on its subjective determination. In determining the CEO compensation, the Committee reviews the objectives of the Company for the previous year and the attainment thereof, principally including the Company's financial performance. For services rendered to IBC in 2001, Mr. Nixon received a cash bonus under IBC's discretionary cash bonus program of $450,000. During 2001, the Company met both the return on average total assets and the return on average total shareholders' equity targets established pursuant to the 1998 Executive Incentive Compensation Plan (the "EICP") by the Committee. Accordingly, Mr. Nixon received an incentive award under the EICP of $550,000 for services rendered to the Company during 2001. The amounts of the cash bonus and the incentive award were largely affected by the strong financial results of the Company during 2001, which included (i) net income of $83.3 million, or $3.15 per share-basic, an amount which represents a 12% increase in earnings per share compared to the previous year, (ii) the Company's excellent return on average total assets of 1.39% and (iii) the Company's strong return on average total shareholders' equity of 17.78%.

        The Salary and Steering Committee has considered the limitations on deductibility of compensation of the named executive officers under Section 162(m) of the Internal Revenue Code. The Steering Committee's current policy is to ensure that substantially all such compensation is deductible under Section 162(m) when paid.

REPORT OF THE STOCK OPTION PLAN COMMITTEE

        The Stock Option Plan Committee of the Board of Directors determines the stock option grants to executive officers and key salaried employees of the Company. During 2001, the Stock Option Plan Committee met and granted options to purchase a total of 229,000 shares of Common Stock to several of the key salaried employees of the Company. The primary purpose of the Company's Stock Option Plan is to increase the interest of the executive and key salaried employees of the Company, the subsidiary banks and non- bank subsidiaries in its future growth and success through the added incentive created by the opportunity afforded for stock ownership under the Plan. The size of the option grants were determined by the Stock Option Plan Committee based upon a subjective assessment of the respective employee's

8



performance, compensation level and other factors. The exercise price of each option equaled the fair market value of the Common Stock as of the date of grant.

REPORT OF THE AUDIT COMMITTEE

        The Company's Audit Committee is responsible for providing objective and independent oversight of the Company's accounting functions and internal controls. Such oversight responsibility includes, but is not limited to, making recommendations concerning the engagement of independent auditors, reviewing the consolidated financial statements and the scope of the independent annual audit, reviewing and reassessing the adequacy of the Audit Committee's charter, reviewing with the independent auditors the results of their audit, considering the range of audit and non-audit fees, monitoring internal financial and accounting controls and performing such other oversight functions as may be requested from time to time by the Board of Directors. The Audit Committee reviewed the audited financial statements of the Company as of and for the fiscal year ended December 31, 2001, with management and the independent auditors. Management has the responsibility for the preparation, presentation and integrity of the Company's financial statements and the independent auditors have the responsibility for auditing the Company's financial statements and expressing an opinion as to their conformity with generally accepted accounting principles in the United States.

REPORT:

        The Audit Committee has:

        —reviewed and discussed the audited financial statements with management;

        —discussed with the independent auditors the matters required to be discussed by SAS 61; and

        —received the required information and communications from the independent auditors required by Independence Standards Board Standard No. 1, and discussed with the auditors the auditors' independence.

        Based on the review and discussions with management and the Company's independent auditors referenced above, the Audit Committee has recommended to the Board of Directors that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2001 filed with the SEC.

        The Board of Directors has determined that the members of the Audit Committee are "independent" as defined in Rule 4200(a)(15) of the National Association of Securities Dealers listing standards. The Audit Committee has adopted a written charter.

PRINCIPAL ACCOUNTING FIRM FEES

        The following table sets forth the aggregate fees billed to International Bancshares Corporation for the year ended December 31, 2001 by the Company's principal accounting firm, KPMG LLP.

Audit Fees, Excluding audit related fees (1)   $ 279,300
Financial Information Systems Design and Implementation Fees     0
All other fees      
  Audit related fees (2)     73,900
  Other Non-audit services (3)     200,800
    Total All Other Fees   $ 274,700

(1)
Audit fees related to the audit of the Company's consolidated financial statements as of and for the year ended December 31, 2001 and limited reviews of the Company's unaudited consolidated quarterly financial statements.

(2)
Audit related fees consisted principally of fees related to the audits of Company's Employee's Profit Sharing Plan, a broker-dealer subsidiary and FDICIA attestation reports.

(3)
Other non-audit related fees consisted principally of research and consultation on tax issues and filing of tax returns.

        The Audit Committee has considered whether the provision of services covered in billings included under the "Other Non-audit Services" category listed above is compatible with maintaining the principal auditors' independence. The Audit Committee has concluded that the provisions of such non-audit services would not jeopardize the independence of KPMG LLP as the Company's principal auditors.

COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

INTEREST OF MANAGEMENT IN
CERTAIN TRANSACTIONS

        Some of the directors, executive officers and nominees for directors of the Company and principal shareholders of the Company and their immediate families and the companies with which they are associated were customers of, and had banking transactions with, the Company's subsidiary banks in the ordinary course of the subsidiary banks' business during 2001, and the Company anticipates that such banking transactions will continue in the future. All loans and commitments to loan included in such banking transactions were made in the ordinary course of business, on substantially the same terms, including interest rates and collateral, as those prevailing in the industry at the time for comparable transactions with other persons, and, in the opinion of management of the Company, did not involve more than a normal risk of collectibility or present other unfavorable features.

11



        During 1994, the Company obtained approval from the Federal Reserve Bank of Dallas to engage in the activity of making loans to certain of its executive officers, directors, affiliates, and principal shareholders, and to certain executive officers and directors and their related interests of the subsidiary banks. In connection with such approval, the Company committed that all loans would be on terms and under circumstances, including credit standards, that are substantially the same or at least as favorable to the Company as those prevailing at the time for comparable transactions with or involving other non-affiliated borrowers, or in the absence of comparable transactions, on terms and under circumstances, including credit standards, that in good faith would be offered to or would apply to non-affiliated companies. As of December 31, 2001, loans outstanding made by the Company to such persons or entities aggregated $5,637,688 and all of said loans, which are described in the following paragraph, were made on terms and under circumstances consistent with the commitment made by the Company to the Federal Reserve Bank of Dallas. At December 31, 2001, all of the loans outstanding in the aggregate principal amount of $5,637,688 were current with respect to principal and interest.

        As of December 31, 2001, all loans to IBC Partners Investment Joint Venture and IBC Partners Organizational Joint Venture by the Company were paid in full. The two loans were extended as part of a single credit facility in connection with the formation of IBC Partners, Ltd. The two joint ventures are controlled by certain directors and executive officers of the Company or its subsidiary banks. The joint ventures repaid $25,372 and $89,708, respectively, on the credit facility during 2001. As of December 31, 2001, Dennis E. Nixon and his related interests were indebted to the Company in the amount of $5,637,688 in connection with two real estate loans. Mr. Nixon and his related interests repaid $2,561,549 and initiated new advances of $3,968,497 on the related loans during 2001. As of December 31, 2001 all loans to R. David Guerra and his related interests by the Company were paid in full. Mr. Guerra repaid $185,000 on the loans from the Company during 2001.

        IBC and Sanchez Oil & Gas Corporation, a related interest of Antonio R. Sanchez, Jr., who is a director and principal shareholder of the Company, jointly own, in varying percentages certain aircraft used for business purposes by IBC, the other bank subsidiaries and Sanchez Oil and Gas Corporation. The net book value of IBC's aggregate interest in such aircraft as of April 4, 2002 was approximately $2.9 million. Each bank subsidiary and Sanchez Oil and Gas Corporation pay the pro rata expense related to their actual use of the aircraft.


Filing of Beneficial Ownership Reports

        Under the securities laws of the United States, the Company's directors, its executive officers and any persons holding more than ten percent of the Company's Common Stock are required to report their initial ownership of the Company's Common Stock and any subsequent changes in that ownership to the Securities and Exchange Commission. Specific due dates for these reports have been established and the Company is required to disclose in this proxy statement any failure to file such reports by the applicable dates during 2001. The Company believes that all of these filing requirements were timely satisfied, except that Antonio R. Sanchez, Jr. inadvertently failed to timely file a Form 4 relating to four trust distribution transactions. Upon discovery of such failure, Mr. Sanchez included the transactions in a subsequent Form 4. In making these disclosures, the Company has relied solely on written representations of its directors, executive officers and its ten percent holders and copies of the reports that they have filed with the Commission.


PROPOSAL—2

APPOINTMENT OF INDEPENDENT AUDITORS

        The Board of Directors of the Company has appointed the firm of KPMG LLP to audit the accounts of the Company for the 2002 fiscal year. The firm has audited the books of the Company and its predecessor, IBC, annually since 1979.

12



        Audit services rendered by KPMG LLP for the fiscal year ended December 31, 2001 included the annual examination of the Company's consolidated financial statements, which are included in reports to shareholders and the Securities and Exchange Commission; and consultation on accounting and related matters and services performed in connection with other regulatory filings.

        Representatives of KPMG LLP are expected to be present at the annual meeting of shareholders with the opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions.

        Approval of the appointment of independent auditors is not a matter which is required to be submitted to a vote of shareholders, but the Board of Directors considers it appropriate for the shareholders to express whether they approve or withhold their approval of the appointment. If shareholder approval should be withheld, the Board of Directors would consider an alternative appointment for the succeeding fiscal year. The Board of Directors of the Company recommends that the shareholders approve the appointment of KPMG LLP as the independent auditors. The affirmative vote of a majority of the shares present and entitled to vote thereon will constitute approval.


PROPOSAL—3

INCREASE IN AUTHORIZED SHARES PROPOSAL

INTRODUCTION

        The Company is proposing to amend its Articles of Incorporation to increase the authorized number of shares of Common Stock, $1.00 par value per share, from 40,000,000 to 105,000,000 (the "Increase in Authorized Share Proposal"). The Company is requesting its shareholders to approve the proposed increase in the number of authorized shares of Common Stock.

        For the reasons set forth below, the Board of directors believes that the best interests of the Company and its shareholders will be served if the Company's Articles of Incorporation are amended to increase the authorized number of shares of Common Stock, $1.00 par value per share, from 40,000,000 to 105,000,000 shares. The Board of Directors has unanimously approved and recommends a vote "FOR" the Increase in Authorized Shares Proposal.

AMENDMENT TO ARTICLES OF INCORPORATION TO INCREASE THE AUTHORIZED SHARES OF COMMON STOCK

        The Board of Directors has approved for submission to the shareholders a proposal relating to the amendment of Article IV of the Articles of Incorporation of the Company to increase the number of authorized shares of Common Stock, par value $1.00 per share, from 40,000,000 to 105,000,000. The additional 65,000,000 shares of Common Stock, which will be authorized if this proposal is approved, will increase the number of authorized, unissued and unreserved shares of Common Stock of the Company. Currently, before the proposed increase, the number of authorized, unissued, and non-treasury shares of Common Stock of the Company is 6,746,288. Of this amount, 1,532,779 shares are reserved for issuance pursuant to the exercise of certain stock options of the Company. The newly authorized shares would, if and when issued, have the same rights and privileges as the shares of Common Stock presently outstanding. The holders of Common Stock have no preemptive rights to acquire any of the Company's Common Stock under the existing Articles of Incorporation and will not have any such rights if this proposal is approved.

        The Board of Directors believes that it is desirable to have the additional authorized shares of Common Stock available for stock dividends or splits, stock options, future financing and acquisition transactions, or other general corporate purposes as well as to enable the Company to take advantage of favorable opportunities which may arise in the future. The additional shares of Common Stock would be available for issuance without further action by the shareholders and without the accompanying delay and

13



expense involved in calling a special meeting of shareholders, except as may otherwise be required by law. The issuance of any additional shares of Common Stock may result in a dilution of the voting power of the shareholders, as well as their respective equity interests in the Company. At the date of this Proxy Statement, the Company has no arrangements, commitments or plans with respect to the sale or issuance of any of the additional shares of Common Stock as to which authorization is sought, except for a 25% stock split-up effected through a stock dividend declared on April 4, 2002, subject to approval by the shareholders of the Increase in Authorized Shares Proposal.

        In addition, the Board could use the authorized but unissued shares of Common Stock to create impediments to a takeover or a change of control of the Company. Under certain circumstances, such shares could be used to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control of the Company. For example, the Company might seek to frustrate a takeover attempt by making a private sale of a large block of shares to a third party who was opposed to such an attempt. The increase in authorized stock might also be considered as having the effect of discouraging an attempt by a third party to acquire control of the Company, through the acquisition of a substantial number of shares, since the issuance of any shares could be used to dilute the stock ownership of shares of the Company's voting stock held by such third party. Accordingly, an effect of the increase in the number of authorized shares of Common Stock may be to deter a future takeover attempt. The Board is not presently aware of any plans to acquire control of the Company and has not proposed the amendment to the Articles of Incorporation as an anti-takeover measure.

        The proposed amendments to the Company's Articles of Incorporation would cause Article IV thereof to read in its entirety as follows:

        The aggregate number of shares which the corporation shall have the authority to issue is One Hundred Five Million (105,000,000) shares of Common Stock of the par value of One Dollar ($1.00) per share.

VOTE REQUIRED FOR APPROVAL

        Approval of the Amendment to Article IV requires the affirmative vote of the holders of a majority of the shares of Common Stock entitled to vote on such matter. THE BOARD OF DIRECTORS HAS APPROVED AND RECOMMENDS THAT YOU VOTE "FOR" THE PROPOSED AMENDMENT TO ARTICLE IV OF THE COMPANY'S ARTICLES OF INCORPORATION. Unless otherwise specified, all properly executed proxies received by the Company will be voted in favor of the approval of the amendment.


SHAREHOLDER PROPOSALS FOR YEAR 2003 ANNUAL MEETING

        The 2003 Annual Meeting of Shareholders will be held on May 19, 2003.
