Proxy Statement for the
Annual Meeting of Shareholders
To Be Held on Thursday, February 15, 2007

This Proxy Statement is furnished in connection with a solicitation of proxies by the Board of Trustees (the "Board") of Credit Suisse High Yield Bond Fund (the "Fund") for use at the Annual Meeting of Shareholders of the Fund to be held at the offices of Credit Suisse Asset Management, LLC ("Credit Suisse"), Eleven Madison Avenue, 24th Floor, New York, New York 10010 on Thursday, February 15, 2007 (commencing at 3:00 p.m. New York time) and at any adjournments thereof (the "Meeting"). A Notice of Annual Meeting of Shareholders and a proxy card (the "Proxy") accompany this Proxy Statement.

Proxy solicitations will be made primarily by mail, but solicitations may also be made by telephone, telegraph or personal interviews conducted by officers or employees of the Fund, Credit Suisse, the investment adviser to the Fund, State Street Bank & Trust Company, the administrator of the Fund (the "Administrator"), or D.F. King & Co., Inc. ("D.F. King"), a professional proxy solicitation firm that has been retained by the Fund for a fee not to exceed $1,500 plus all reasonable out of pocket expenses (i.e., shareholder telephone calls, etc.) incurred on behalf of the Fund. All costs of solicitation, including (a) printing and mailing of this Proxy Statement and accompanying material, (b) the reimbursement of brokerage firms and others for their expenses in forwarding solicitation material to the beneficial owners of the Fund's shares, (c) payment of D.F. King for its services in soliciting Proxies and (d) supplementary solicitations to submit Proxies, will be borne by the Fund. This Proxy Statement is expected to be mailed to shareholders on or about December 29, 2006.

The principal executive office of Credit Suisse is Eleven Madison Avenue, 24th Floor, New York, New York 10010. The principal executive office of the Administrator is 225 Franklin Street, Boston, Massachusetts 02110.

The Fund's Annual Report containing audited financial statements for the fiscal year ended October 31, 2006 is being furnished to all shareholders of the Fund along with this Proxy in a combined mailing. It is not to be regarded as proxy-soliciting material.

Only shareholders can attend the Meeting and any adjournment or postponement thereof. To gain admittance, if you are a shareholder of record, you must bring a form of personal identification to the Meeting, where your name will be verified against our shareholder list. If a broker or other nominee holds your shares and you plan to attend the Meeting, you should bring a recent brokerage statement showing your ownership of the shares, as well as a form of personal identification. Shareholders who wish to vote in person at the Meeting must comply with all applicable conditions.

If the enclosed Proxy is properly executed and returned in time to be voted at the Meeting, the shares represented thereby will be voted in accordance with the instructions marked on the Proxy. Any shareholder giving a Proxy has the right to attend the Meeting to vote his or her shares in person (thereby revoking any prior Proxy) and also the right to revoke the Proxy at any time by written notice received by the Fund prior to the time it is voted.

1

---

The presence in person or by proxy of the holders of a majority of the shares entitled to be cast shall be necessary and sufficient to constitute a quorum for the transaction of business. In the event that a quorum is not present at the Meeting, the holders of a majority of the shares present in person or by proxy will have the power to adjourn the Meeting, without notice other than an announcement at the Meeting, until the requisite number of shares entitled to vote at the Meeting is present. In the event that a quorum is present at the Meeting but sufficient votes to approve the proposal are not received, the persons named as proxies may propose one or more adjournments of the Meeting to permit further solicitation of Proxies. Any such adjournment will require the affirmative vote of a majority of those shares presented at the Meeting in person or by proxy, and the persons named as proxies will vote those Proxies that they are entitled to vote "FOR" any proposal in favor of such adjournment and will vote those Proxies required to be voted "AGAINST" any proposal against any such adjournment. Absent the establishment of a subsequent record date and the giving of notice to the holders of record thereon, the adjourned Meeting must take place not more than 130 days after the record date. At such adjourned Meeting, any business may be transacted which could have been transacted at the original Meeting.

A Proxy that is properly executed and returned accompanied by instructions to withhold authority to vote (an abstention) or that represents a broker "non-vote" (that is, a Proxy from a broker or nominee indicating that such person has not received instructions from the beneficial owner or other person entitled to vote shares on a particular matter with respect to which the broker or nominee does not have discretionary power) will be treated as shares that are present, but that have not voted, for the purpose of determining a quorum for the transacting of business. Under Delaware law, abstentions and broker non-votes do not constitute a vote "FOR" or "AGAINST" a matter. The election of a Trustee requires that the successful candidate receive a plurality of votes cast at the Meeting in person or by proxy; therefore, abstentions and broker non-votes will be disregarded.

Credit Suisse and its affiliates have advised the Fund that they intend to vote the shares over which they have voting power at the Meeting, including shares that are held directly or on behalf of employees, in the manner instructed by the customers or employees for which such shares are held.

The Fund has one class of shares of beneficial interest of capital stock (the "Shares"). On the record date, December 22, 2006, there were 55,458,814 Shares outstanding. Each Share is entitled to one vote at the Meeting, and fractional Shares are entitled to a proportionate share of one vote.

In order that your Shares may be represented at the Meeting, you are requested to:

—indicate your instructions on the Proxy;

—date and sign the Proxy;

—mail the Proxy promptly in the enclosed envelope; and

—allow sufficient time for the Proxy to be received and processed on or before 3:00 p.m. on February 15, 2007.

⁽¹⁾   This information has been furnished by each Trustee as of November 30, 2006. "Beneficial Ownership" is determined in accordance with Rule 16a-1(a)(2) promulgated under the Securities Exchange Act of 1934 (the "1934 Act").

⁽²⁾   The Fund's Trustees and officers, in the aggregate, own less than 1% of the Fund's outstanding equity securities.

⁽³⁾   "Credit Suisse Family of Investment Companies" means those registered investment companies that share Credit Suisse as their investment adviser and that hold themselves out to investors as related companies for purposes of investment and investor services.

⁽⁴⁾   Ms. Bovarnick was appointed to the Board on July 1, 2006.

As of November 30, 2006, neither the non-interested nominees for election to the Board, nor the other non-interested Trustees nor their immediate family members owned beneficially or of record any class of securities in Credit Suisse or in a person (other than a registered investment company) directly or indirectly controlling, controlled by or under common control with Credit Suisse.

During the fiscal year ended October 31, 2006, each Trustee who was not a director, officer, partner, co-partner or employee of Credit Suisse, the Administrator or any affiliate thereof, received an annual fee of $12,500 and $1,000 for each meeting of the Board attended by him and was reimbursed for expenses incurred in connection with his attendance at the Fund's Board meetings. The total remuneration paid or accrued by the Fund during the fiscal year ended October 31, 2006 to all such unaffiliated Trustees was $95,806. Each Trustee entitled to a fee from the Fund receives fifty percent of his annual fee in the form of Fund shares purchased by the Fund's transfer agent in the open market on his behalf.

Messrs. Arzac, Cattano, Fox, Rappaport and Ms. Bovarnick constitute the Fund's Audit Committee, which is composed of Trustees who are not interested persons of the Fund and who are independent (as such term is defined by the listing standards of American Stock Exchange (the "AMEX")). The Audit Committee convened four times during the fiscal year ended October 31, 2006. The Audit Committee advises the full Board with respect to accounting, auditing and financial matters affecting the Fund.

The Trustees constituting the Fund's Audit Committee also constitute the Fund's Nominating Committee, which is composed of Trustees who are not interested persons of the Fund and who are independent (as such term is defined by the listing standards of AMEX). The Nominating Committee met five times during the fiscal year ended October 31, 2006. At a meeting of the Nominating Committee held on November 16, 2006, the Nominating Committee (with the nominee abstaining from voting) nominated each of Messrs. Fox and Haber for a three-year term and nominated Ms. Bovarnick for a one-year term. The Nominating Committee selects and nominates new Trustees. The Board has adopted a Nominating Committee Charter (a copy of which was included as Appendix A to the Fund's proxy statement dated January 11, 2005). In nominating candidates, the Nominating Committee will take into consideration such factors as it deems appropriate. These factors may include judgment, skill, diversity, experience with investment companies and other organizations of comparable purpose, complexity, size and subject to similar legal restrictions and oversight, the interplay of the candidate's experience with the experience of other Board members, and the extent to which the candidate would be a desirable addition to the Board and any committees thereof.

The Nominating Committee will consider candidates submitted by shareholders or from other sources it deems appropriate. Any recommendation should be submitted to the Secretary of the Fund, c/o Credit Suisse Asset Management, LLC, Eleven Madison Avenue, 24th Floor, New York, New York 10010. Any submission should include at a minimum the following information: As to each individual proposed for election or re-election as Trustee, the name, age, business address, residence address and principal occupation or employment of such individual, the class, series and number of shares of stock of the Fund that are beneficially owned by such individual, the date such shares were acquired and the investment intent of such acquisition, whether such stockholder believes such individual is, or is not, an "interested person" of the Fund (as defined in the 1940 Act), and information regarding such individual that is sufficient, in the discretion of the Nominating Committee, to make such determination, and all other information relating to such individual that is required to be disclosed in solicitation of proxies for election of Trustees in an election contest (even if an election contest is not involved) or is otherwise required, in each case pursuant to Regulation 14A (or any successor provision) under the 1934 Act, and the rules thereunder (including such individual's written consent to being named in the proxy statement as a nominee and to serving as a Trustee (if elected)). In the case of the Fund holding a meeting of shareholders, any such submission, in order to be considered for inclusion in the Fund's proxy statement, should be submitted by a date not later than the 120th calendar day before the date the Fund's proxy statement was released to security holders in connection with the Fund's previous year's annual meeting or, if the Fund has changed the meeting date by more than 30 days or if no meeting was held the previous year, within a reasonable time before the Fund begins to print and mail its proxy statement. Any such submission must also be submitted by such date and contain such information as may be specified in the Fund's By-laws, or as required by any relevant stock exchange listing standards.

The Fund does not have a Compensation Committee.

OTHER BOARD-RELATED MATTERS

Shareholders who wish to send communications to the Board should send them to the address of the Fund and to the attention of the Board. All such communications will be directed to the Board's attention.

The Fund does not have a formal policy regarding Board member attendance at the Annual Meeting of Shareholders.

AUDIT COMMITTEE REPORT

Pursuant to the Audit Committee Charter adopted by the Board (a copy of which was included as Appendix B to the Fund's proxy statement dated January 11, 2005), the Audit Committee is responsible for conferring with the Fund's independent registered public accounting firm, reviewing annual financial statements, approving the selection of the Fund's independent registered public accounting firm and overseeing the Fund's internal controls. The Fund's Audit Committee charter also contains provisions relating to the pre-approval by the Audit Committee of certain non-audit services to be provided by PricewaterhouseCoopers LLP ("PwC") to the Fund and to Credit Suisse and certain of its affiliates. The Audit Committee advises the full Board with respect to accounting, auditing and financial matters affecting the Fund. The independent registered public accounting firm is responsible for planning and carrying out the proper audits and reviews of the Fund's financial statements and expressing an opinion as to their conformity with accounting principles generally accepted in the United States of America.

The Audit Committee has met with the Fund's management to discuss, among other things, the Fund's audited financial statements for the fiscal year ended October 31, 2006. The Audit Committee has also met with the Fund's independent registered public accounting firm, PwC, and discussed with them certain matters required by Statement of Auditing Standards No. 61, Communications with Audit Committees, as currently modified or supplemented, including, but not limited to, the scope of the Fund's audit, the Fund's financial statements and the Fund's accounting controls. The Audit Committee has received from PwC the letter required by the SEC's independence rules describing any relationships between it and the Fund, Credit Suisse and its affiliates that may be thought to bear upon the independence of the independent registered public accounting firm. The Audit Committee has discussed with PwC their independence and has considered whether the provision of services by PwC to the Fund, Credit Suisse and its affiliates was compatible with maintaining PwC's independence.

The members of the Audit Committee are not professionally engaged in the practice of auditing or accounting and are not employed by the Fund for accounting, financial management or internal control. Moreover, the Audit Committee relies on and makes no independent verification of the facts presented to it or representations made by management or the independent registered public accounting firm. Accordingly, the Audit Committee's oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles and policies, or internal controls and procedures, designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee's considerations and discussions referred to above do not provide assurance that the audit of the Fund's financial statements has been carried out in accordance with generally accepted accounting standards or that the financial statements are presented in accordance with generally accepted accounting principles.

Based upon these reviews and discussions, the Audit Committee recommended to the Board that the Fund's audited financial statements be included in the Fund's 2006 Annual Report to Shareholders for the fiscal year ended October 31, 2006 and be mailed to shareholders and filed with the SEC.

A representative of PwC will be available by telephone at the Meeting and will have the opportunity to make a statement, if the representative so desires, and will be available to respond to appropriate questions.

The information in the table below is provided for services rendered to the Fund by PwC for its fiscal years ended October 31, 2005 and October 31, 2006.

⁽²⁾   Tax services in connection with the Fund's excise tax calculations and review of the Fund's applicable tax returns.

The Audit Committee is responsible for pre-approving (i) all audit and permissible non-audit services to be provided by the independent registered public accounting firm to the Fund and (ii) all permissible non-audit services to be provided by the independent registered public accounting firm to Credit Suisse and any service provider to the Fund controlling, controlled by or under common control with Credit Suisse that provided ongoing services to the Fund ("Covered Services Provider") if the engagement relates directly to the operations and financial reporting of the Fund. The Audit Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to the Chairperson of the Audit Committee, and the Chairperson shall report to the Audit Committee, at its next regularly scheduled meeting after the Chairperson's pre-approval of such services, his or her decision(s). The Audit Committee may also establish detailed pre-approval policies and procedures for pre-approval of such services in accordance with applicable laws, including the delegation of some or all of the Audit Committee's pre-approval responsibilities to other persons (other than Credit Suisse or the Fund's officers). Pre-approval by the Audit Committee of any permissible non-audit services shall not be required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, Credit Suisse and any Covered Services Provider constitutes not more than 5% of the total amount of revenues paid by the Fund to its independent registered public accounting firm during the fiscal year in which the permissible non-audit services are provided; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Audit Committee and approved by the Audit Committee (or its delegate(s)) prior to the completion of the audit.

The aggregate fees billed by PwC for non-audit services rendered to the Fund, Credit Suisse or Covered Service Providers for the fiscal years ended October 31, 2005 and October 31, 2006 were $394,000 and $0 respectively.

ADDITIONAL INFORMATION

Beneficial Owners

Based upon the Fund's review of filings made pursuant to Section 13 of the 1934 Act, as of November 30, 2006, the Fund had no knowledge that any shareholder beneficially owned 5% or more of the Fund's shares.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the 1934 Act and Section 30(h) of the 1940 Act require the Fund's officers and trustees, certain officers and directors of the investment adviser, affiliated persons of the investment adviser, and persons who beneficially own more than 10% of the Fund's Shares to file reports of ownership with the SEC and the Fund.

Based solely upon its review of the copies of such forms and written representations received by it, the Fund believes that, for the fiscal year ended October 31, 2006, all filing requirements applicable to such persons were complied with.

Shareholder Proposals

Notice is hereby given that for a shareholder proposal to be considered for inclusion in the Fund's proxy material relating to its 2008 annual meeting of shareholders, the shareholder proposal must be received by the Fund no later than November 17, 2007. The shareholder proposal, including any accompanying supporting statement, may not exceed 500 words.

and a shareholder contemplating submission of a proposal is referred to Rule 14a-8 promulgated under the 1934 Act. The timely submission of a proposal does not guarantee its inclusion in the Fund's proxy materials.

Pursuant to the By-laws of the Fund, at any annual meeting of the shareholders, only such business will be conducted as has been properly brought before the annual meeting. To be properly brought before the annual meeting, the business must be (i) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board, (ii) otherwise properly brought before the meeting by or at the direction of the Board, or (iii) otherwise properly brought before the meeting by a shareholder.

For business to be properly brought before the annual meeting by a shareholder, the shareholder must have given timely notice thereof in writing to the Secretary of the Fund. To be timely, any such notice must be delivered to, or mailed (by certified mail being recommended) to and received by, Credit Suisse High Yield Bond Fund c/o Credit Suisse Asset Management, LLC, Eleven Madison Avenue, 24th Floor, New York, New York 10010 not later than 45 days before the date in the then current year corresponding to the date on which the Fund first mailed its notice and proxy materials for the annual meeting held in the prior year; provided, however, that in the event that the date of the annual meeting is advanced or delayed by more than 30 days from the first anniversary of the preceding year's annual meeting, notice by such shareholder to be timely must be so received not later than the close of business on the 10th day following the day on which notice or public announcement of the date of such meeting was given or made. In no event shall the public announcement of an adjournment of an annual meeting commence a new time period for the giving of a shareholder's notice as described above.

Any such notice by a shareholder shall set forth as to each matter the shareholder proposes to bring before the annual meeting: (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and address, as they appear on the Fund's books, of the shareholder proposing such business, (iii) the class and number of shares of the capital stock of the Fund which are beneficially owned by the shareholder, (iv) a representation that the shareholder is a holder of record of shares of the Fund entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to present such business, (v) whether the shareholder intends or is part of a group which intends to solicit proxies from other shareholders in support of such business and (vi) any material interest of the shareholder in such business.

The Fund may exercise discretionary voting authority with respect to any shareholder proposals for the 2008 annual meeting of shareholders not included in the proxy statement and form of proxy that are not submitted to the Fund within the time-frame indicated above. Even if timely notice is received, the Fund may exercise discretionary voting authority in certain other circumstances. Discretionary voting authority is the ability to vote proxies that shareholders have executed and returned to the Fund on matters not specifically reflected on the form of proxy.

SHAREHOLDERS WHO DO NOT EXPECT TO BE PRESENT AT THE ANNUAL MEETING AND WHO WISH TO HAVE THEIR SHARES VOTED ARE REQUESTED TO DATE AND SIGN THE ENCLOSED PROXY CARD AND RETURN IT IN THE ENCLOSED ENVELOPE. NO POSTAGE IS REQUIRED IF MAILED IN THE UNITED STATES.

Other Business

Management knows of no business to be presented at the Meeting, other than the matters set forth in this Proxy Statement, but should any other matter requiring the vote of shareholders arise, the proxies will vote thereon according to their best judgment in the interests of the Fund.
