                       CREDIT SUISSE HIGH YIELD BOND FUND
                              466 LEXINGTON AVENUE
                                   16TH FLOOR

                             PROXY STATEMENT FOR THE
                         ANNUAL MEETING OF SHAREHOLDERS
                          TO BE HELD ON APRIL 20, 2006

     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"),
466 Lexington Avenue, 16th Floor, New York, New York 10017 on April 20, 2006
(commencing at 2:00 p.m. New York time) and at any adjournments thereof
(collectively, 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 proxy solicitation
firm that has been retained by the Fund and which will receive a fee not to
exceed $1,500 and will be reimbursed for its reasonable expenses. 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 March 6, 2006.

     Credit Suisse has its principal executive office at 466 Lexington Avenue,
16th Floor, New York, New York 10017. The Administrator has its principal
executive office at 225 Franklin Street, Boston, Massachusetts 02110.

     The Fund's Annual Report containing audited financial statements for the
fiscal year ended October 31, 2005 has been previously furnished to all
shareholders of the Fund. It is not to be regarded as proxy-soliciting material.

     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.

     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 present 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

                                        3


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, February 24, 2006, there were 55,040,639
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 2:00 p.m. on April 20, 2006.

                        PROPOSAL 1: ELECTION OF TRUSTEES

     The only proposal to be submitted at the Meeting will be the election of
three (3) Trustees of the Fund to hold office for the terms set forth below and
until their successors are elected and qualified.

     Pursuant to the Fund's Agreement and Declaration of Trust, the Board is
divided into three classes, each class having a term of three years. Each year
the term of one class will expire. James J. Cattano and Steven N. Rappaport are
each being nominated to serve as a Class I Trustee for a three-year term to
expire at the Fund's 2009 Annual Meeting of Shareholders or until his successor
is duly elected and qualified. Lawrence D. Haber is being nominated to serve as
a Class II Trustee for a one-year term to expire at the Fund's 2007 Annual
Meeting of Shareholders or until his successor is duly elected and qualified.

     Enrique R. Arzac is the Class III Trustee whose term will expire at the
Fund's 2008 Annual Meeting of Shareholders. Lawrence J. Fox is the Class II
Trustee whose term will expire at the Fund's 2007 Annual Meeting of
Shareholders.

     Each nominee has indicated an intention to continue to serve if elected and
has consented to being named in this Proxy Statement.

     The following tables set forth certain information regarding the nominees
for election to the Board, Trustees whose terms of office continue beyond the
Meeting, and the principal officers of the Fund. The current terms of office of
the Fund's officers will end at the Board of Trustees' meeting next following
the Meeting.

(1)  This information has been furnished by each Trustee as of December 31,
     2005. "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)  Messrs. Cattano and Haber were not Trustees during this period.

     As of December 31, 2005, none of the non-interested nominees for election
to the Board, the non-interested Trustees or 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, 2005, 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, 2005 to all such unaffiliated Trustees was $55,500.

     During the fiscal year ended October 31, 2005, the Board convened six
times. Each Trustee attended at least seventy-five percent of the aggregate
number of meetings of the Board and any committees on which he served during the
period for which he was a Trustee.

     Messrs. Arzac, Fox, Rappaport and James S. Pasman, Jr. (a Trustee who is
retiring effective as of the date of the Annual Meeting of Shareholders)
constitute the Fund's Audit Committee, which is composed of Trustees who are
not

                                        9


interested persons of the Fund and who are independent (as such term is defined
by the listing standards of the New York Stock Exchange, Inc. (the "NYSE")). The
Audit Committee convened six times during the fiscal year ended October 31,
2005. 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 the NYSE). The Nominating Committee met five times
during the fiscal year ended October 31, 2005. At a meeting of the Nominating
Committee held on December 6, 2005, the Nominating Committee (with the nominee
abstaining from voting) nominated each of Messrs. Cattano and Rappaport for a
three-year term. At a meeting of the Nominating Committee held on February 15,
2005, the Nominating Committee (with the nominee abstaining from voting)
nominated Mr. Haber for a one-year term. 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

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

reasonable time before the Fund begins to print and mail its proxy statement.

                          REPORT OF THE AUDIT COMMITTEE

     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, 2005. 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 Securities and Exchange Commission's ("SEC") 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 for determining 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 2005 Annual Report to Shareholders for the fiscal year ended October 31,
2005 and be mailed to shareholders and filed with the SEC.

                  INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

     At a meeting held on November 17, 2005, the Fund's Audit Committee approved
the selection of PwC for the fiscal year ending October 31, 2006. PwC has been
the Fund's independent registered public accounting firm since February 1, 2001,
and has informed the Fund that it has no material direct or indirect financial
interest in the Fund. 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, 2004 and October 31, 2005.

----------
(1)  Services include agreed-upon procedures in connection with the Fund's
     semi-annual financial statements ($3,000 in 2004 and $3,150 in 2005),
     the Fund's third quarter 2004 Form N-Q filing ($1,500), and the Fund's
     Debt Covenant Agreement for 2005 ($8,900).

(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, 2004 and October 31, 2005 were $0 and $394,000, respectively.

profit sharing, pension or retirement plans.

                             ADDITIONAL INFORMATION

BENEFICIAL OWNERS

     Based upon the Fund's review of filings made pursuant to Section 13 of the
1934 Act, as of February 23, 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 received by it and
written representations from such persons, the Fund believes that, for the
fiscal year ended October 31, 2005, all filing requirements applicable to such
persons were complied with except for the following:

     A Form 3 was not timely filed to report Dennis M. Schaney's appointment as
Chief Investment Officer of the Fund on April 21, 2005. A Form 3 was filed on
May 19, 2005 to report this event.

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 2007 annual meeting of
shareholders, the shareholder proposal must be received by the Fund no later
than November 1, 2006. The shareholder proposal, including any accompanying
supporting statement, may not exceed 500 words. A shareholder desiring to submit
a proposal must be a record or beneficial owner of Shares with a market value of
at least $2,000 and must have held such Shares for at least one year. Further,
the shareholder must continue to hold such Shares through the date on which the
meeting is held. Documentary support regarding the foregoing must be provided
along with the proposal. There are additional requirements regarding proposals
of

                                       13


shareholders, 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, 466
Lexington Avenue, 16th Floor, New York, New York 10017 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 2007 annual meeting of shareholders not included
in the proxy statement and form of proxy which 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.
