Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of
Credit Suisse High Yield Bond Fund

In planning and performing our audit of the financial statements of Credit
Suisse High Yield Bond Fund  (the Fund) as of and for the year ended
October 31, 2011, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), we considered the Funds
internal control over financial reporting, including controls over
safeguarding securities, as a basis for designing our auditing procedures
for the purpose of expressing our opinion on the financial statements and
to comply with the requirements of Form N-SAR, but not for the purpose of
expressing an opinion on the effectiveness of the Funds internal control
over financial reporting.  Accordingly, we do not express an opinion on the
effectiveness of the Fund's internal control over financial reporting.

The management of the Fund is responsible for establishing and maintaining
effective internal control over financial reporting.  In fulfilling this
responsibility, estimates and judgments by management are required to assess
the expected benefits and related costs of controls.  A funds internal
control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles.  A fund's
internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the fund; (2) provide reasonable assurance
that transactions are recorded as necessary to permit preparation of
financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the fund are being
made only in accordance with authorizations of management and trustees
of the fund; and (3)  provide reasonable assurance regarding prevention
or timely detection of unauthorized acquisition, use or disposition of
a funds assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements.  Also, projections
of any evaluation of effectiveness to future periods are subject to
the risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or
procedures may deteriorate.

A deficiency in internal control over financial reporting exists
when the design or operation of a control does not allow management
or employees, in the normal course of performing their assigned
functions, to prevent or detect misstatements on a timely basis.
A material weakness is a deficiency, or a combination of deficiencies,
in internal control over financial reporting, such that there is a
reasonable possibility that a material misstatement of the fund's annual
or interim financial statements will not be prevented or detected on a
timely basis.

Our consideration of the Funds internal control over financial
reporting was for the limited purpose described in the first paragraph
and would not necessarily disclose all deficiencies in internal control
over financial reporting that might be material weaknesses under standards
established by the Public Company Accounting Oversight Board (United
States). However, we noted no deficiencies in the Funds internal control
over financial reporting and its operation, including controls over
safeguarding securities, that we consider to be material weaknesses as
defined above as of October 31, 2011.

This report is intended solely for the information and use of management
and the Board of Trustees of Credit Suisse High Yield Bond Fund and the
Securities and Exchange Commission and is not intended to be and should
not be used by anyone other than these specified parties.
