INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Trustees of
Morgan Stanley Insured Municipal Bond Trust:

In planning and performing our audit of the financial statements
of Morgan Stanley Insured Municipal Bond Trust (the "Trust")
for the year ended October 31, 2003 (on which we have issued
our report dated December 15, 2003), we considered its internal
control, including control activities for safeguarding securities,
in order to determine our auditing procedures for the purpose of
expressing our opinion on the financial statements and to
comply with the requirements of Form N-SAR, and not to
provide assurance on the Trust's internal control.

The management of the Trust is responsible for establishing and
maintaining internal control.  In fulfilling this responsibility,
estimates and judgments by management are required to assess
the expected benefits and related costs of controls.  Generally,
controls that are relevant to an audit pertain to the entity's
objective of preparing financial statements for external purposes
that are fairly presented in conformity with accounting
principles generally accepted in the United States of America.
Those controls include the safeguarding of assets against
unauthorized acquisition, use, or disposition.

Because of inherent limitations in any internal control,
misstatements due to error or fraud may occur and not be
detected.  Also, projections of any evaluation of internal control
to future periods are subject to the risk that the internal control
may become inadequate because of changes in conditions or that
the degree of compliance with policies or procedures may
deteriorate.

Our consideration of the Trust's internal control would not
necessarily disclose all matters in the internal control that might
be material weaknesses under standards established by the
American Institute of Certified Public Accountants.  A material
weakness is a condition in which the design or operation of one
or more of the internal control components does not reduce to a
relatively low level the risk that misstatements caused by error
or fraud in amounts that would be material in relation to the
financial statements being audited may occur and not be
detected within a timely period by employees in the normal
course of performing their assigned functions.  However, we
noted no matters involving the Trust's internal control and its
operation, including controls for safeguarding securities, that we
consider to be material weaknesses as defined above as of
October 31, 2003.

This report is intended solely for the information and use of
management, the Shareholders and Board of Trustees of Morgan
Stanley Insured Municipal Bond Trust, and the Securities and
Exchange Commission and is not intended to be and should not
be used by anyone other than these specified parties.
