                                PROXY STATEMENT
                             ----------------------

                     FOR THE ANNUAL MEETING OF SHAREHOLDERS
                        TO BE HELD ON NOVEMBER 11, 2004

         This proxy statement is furnished in connection with the solicitation
by the Board of Trustees of MBIA Capital/Claymore Managed Duration Investment
Grade Municipal Fund (the "Fund") of proxies to be used at the Annual Meeting of
Shareholders (the "Meeting") of the Fund to be held at the offices of Simpson
Thacher & Bartlett LLP, 425 Lexington Avenue, New York, New York 10017, on
November 11, 2004 at 11:00 a.m., New York City Time (and at any adjournment or
postponements thereof) for the purposes set forth in the accompanying Notice of
Annual Meeting of Shareholders. This proxy statement and the accompanying form
of proxy are first being mailed to shareholders on or about September 29, 2004.
Shareholders who execute proxies retain the right to revoke them in person at
the Meeting or by written notice received by the Secretary of the Fund at any
time before they are voted. Unrevoked proxies will be voted in accordance with
the specifications thereon and, unless specified to the contrary, will be voted
FOR the election of Trustees. The close of business on September 24, 2004 has
been fixed as the record date for the determination of shareholders entitled to
notice of and to vote at the Meeting. Each shareholder is entitled to one vote
for each full share and an appropriate fraction of a vote for each fractional
share held. On September 24, 2004 there were 7,935,591 shares of the Fund's
common shares outstanding and 2,778 shares of the Fund's preferred shares
outstanding. These classes of stock are the only classes of stock currently
authorized by the Fund.

         In accordance with the Fund's Amended and Restated Agreement and
Declaration of Trust, a quorum is constituted by the presence in person or by
proxy of the holders of record of a majority of the common shares and preferred
shares of the Fund entitled to vote at the Meeting except that a quorum for the
election of Messrs. Mark Jurish and Ronald E. Toupin, Jr., as discussed below,
is constituted by the presence in person or by proxy of the holders of record of
a majority of the preferred shares of the Fund entitled to vote at the meeting.
In the event that a quorum is not present at the Meeting or, in the event that a
quorum is present but sufficient votes have not been received to approve a
proposal, the Meeting may be adjourned to permit further solicitation of
proxies. The presiding officer of the Fund for the Meeting or the affirmative
vote of a majority of the persons designated as proxies may adjourn the Meeting
to permit further solicitation of proxies or for other reasons consistent with
Delaware law and the Fund's Amended and Restated Agreement and Declaration of
Trust and By-Laws. Unless otherwise instructed by a shareholder granting a
proxy, the persons designated as proxies may use their discretionary authority
to vote on questions of adjournment.

         At the Meeting, the preferred shareholders of the Fund will have equal
voting rights (i.e., one vote per share) with the Fund's common shareholders
and, except as shown in the summary chart below, will vote together with common
shareholders as a single class on all proposals to be brought before the
Meeting. As summarized below, the preferred shareholders of the Fund, voting as
a separate class, will have the right to vote on the election of the preferred
shares Trustees. The two Trustees that have been designated as representing the
holders of the Fund's preferred shares are Messrs. Mark Jurish and Ronald E.
Toupin, Jr. Common shareholders will not participate in the election of these
Trustees.

                        PROPOSAL 1: ELECTION OF TRUSTEES

         In accordance with the Fund's Amended and Restated Agreement and
Declaration of Trust, the Fund's Board of Trustees will, commencing with this
Meeting, be divided into three classes: Class I, Class II and Class III. At the
Meeting, shareholders will be asked to elect two Class I, two Class II and two
Class III Trustees. The terms of office of the Class I, Class II and Class III
Trustees expire at the year 2005, 2006 and 2007 annual meetings of shareholders,
respectively, or thereafter in each case when their respective successors are
duly elected and qualified. Upon the expiration of the term of office of each
class as set forth above, the number of Trustees in such class, as determined by
the Board of Trustees, shall be elected for a term expiring on the date of the
third annual meeting of shareholders or special meeting in lieu thereof
following such expiration to succeed the Trustees whose terms of office expire.
The effect of these staggered terms is to limit the ability of other entities or
persons to acquire control of the Fund by delaying the replacement of a majority
of the Board of Trustees.

         The persons named in the proxy intend to vote at the Meeting (unless
directed not to vote) FOR the election of the nominees named below. All of the
nominees are currently members of the Fund's Board of Trustees. Each nominee has
indicated that he will serve if elected, but if any nominee should be unable to
serve, the proxy will be voted for any other person determined by the persons
named in the proxy in accordance with their judgment.

         A Fund Complex means two or more registered investment companies that
hold themselves out to investors as related companies for purposes of investment
and investor services, or that have a common investment adviser or that have an
investment adviser that is an affiliated person of the investment adviser of any
of the other registered investment companies. Investment companies are
considered to be in the same family if they share the same investment adviser or
principal underwriter and hold themselves out to investors as related companies
for purposes of investment and investor services. Currently, the Fund is not
part of a Fund Complex.

BOARD COMMITTEES AND MEETINGS

BOARD OF TRUSTEES AND MEETINGS. The Board of Trustees is responsible for
ensuring that the Fund is managed in the best interest of its shareholders. The
Trustees oversee the Fund's business by, among other things, meeting with the
Fund's management and evaluating the performance of the Fund's service providers
including MBIA-CMC, the custodian, the transfer agent, the servicing agent and
the administrator. As part of this process, the Trustees consult with the Fund's
independent auditors and with their own separate independent counsel.

         During the fiscal year ended July 31, 2004, the Board of Trustees met
seven times. Each Trustee attended at least 75% of the aggregate number of
meetings of the Board and the committees for which he was eligible. The Fund
does not have a formal policy regarding attendance by Trustees at annual
meetings of shareholders. This Meeting is the Fund's first annual meeting of
shareholders.

         The Board has an Audit Committee and a Nominating Committee which meet
periodically during the year and whose responsibilities are described below. The
Fund also has an Executive Committee.

AUDIT COMMITTEE. The Fund's Audit Committee is currently composed of Messrs.
Jurish, Nyberg, Rosenbloom and Toupin, all of whom have been determined not to
be "interested persons" of the Fund, MBIA-CMC or its affiliates within the
meaning of the 1940 Act, and who are "independent" as defined in the New York
Stock Exchange listing standards. The Audit Committee is, among other things,
responsible for: (i) overseeing the Fund's accounting and financial reporting
policies and practices, its internal controls over financial reporting and the
quality, integrity and objectivity of the Fund's financial statements and the
independent audit thereof, (ii) approving prior to appointment the engagement of
the Fund's independent auditors, (iii) selecting, overseeing and setting the
compensation of the Fund's independent auditors, and (iv) discussing the Fund's
annual audited financial statements and semi-annual financial statements with
management and the independent auditors. This Committee met six times during the
fiscal year ended July 31, 2004. The Fund adopted an Audit Committee Charter at
a meeting held on July 21, 2003, as amended at a meeting held on July 15, 2004,
a copy of which is attached to this Proxy Statement as Annex A.

NOMINATING COMMITTEE. The Nominating Committee, the principal function of which
is to select and nominate persons for election as Trustees of the Fund, is
currently composed of Messrs. Jurish, Nyberg, Rosenbloom and Toupin. Only
Trustees who are not "interested persons" of the Fund, MBIA-CMC or its
affiliates within the meaning of the 1940 Act and who are "independent" as
defined in the New York Stock Exchange listing standards are members of the
Nominating Committee. The Nominating Committee may accept nominees recommended
by the shareholders as it deems appropriate. Shareholders who wish to recommend
a nominee should send nominations which include biographical data and set forth
the qualifications of the proposed nominee to the Fund's Secretary. The
Nominating Committee met once during the Fund's fiscal year ended July 31, 2004.
The Fund adopted a Nominating Committee Charter at a meeting held on July 15,
2004, a copy of which is attached to this Proxy Statement as Annex B.

         The Nominating Committee identifies potential nominees through its
network of contacts, and may also engage, if it deems appropriate, a
professional search firm. While the Nominating Committee meets to discuss and
consider such candidates' qualifications and then chooses a candidate by
majority vote, the Nominating Committee does not have specific, minimum
qualifications for nominees and has not established specific qualities or skills
that it regards as necessary for one or more of the Fund's Trustees to possess
(other than any qualities or skills that may be required by applicable law,
regulation or listing standard). However, as set forth in the Nominating
Committee Charter, in evaluating a person as a potential nominee to serve as a
Trustee of the Fund, the Committee may consider the following factors, among any
others it may deem relevant:

     o  whether or not the individual is an "interested person" as defined in
        the 1940 Act and whether the person is otherwise qualified under
        applicable laws and regulations to serve as a Trustee of the Fund;

     o  whether or not the individual has any relationships that might impair
        his or her independence, such as any business, financial or family
        relationships with Fund management, the investment manager of the Fund,
        Fund service providers or their affiliates;

     o  whether or not the individual serves on boards of, or is otherwise
        affiliated with, competing financial service organizations or their
        related mutual fund complexes;

     o  whether or not the individual is willing to serve, and willing and able
        to commit the time necessary for the performance of the duties of a
        Trustee of the Fund;

     o  the contribution which the individual can make to the Board and the Fund
        with consideration being given to the individual's educational
        background and business and professional experience;

     o  the character and integrity of the individual; and

     o  the overall diversity of the Board's composition.

                                       5

         The nominees for election at the Meeting currently serve as Trustees
and were unanimously nominated by the Board of Trustees and the Nominating
Committee.

REPORT OF THE AUDIT COMMITTEE

         Pursuant to meetings of the Audit Committee on July 15, 2004 and
September 15, 2004, the Audit Committee reports that it has: (i) reviewed and
discussed the Fund's audited financial statements with management; (ii)
discussed with PricewaterhouseCoopers LLP ("PwC"), the Independent Registered
Public Accounting Firm to the Fund, the matters (such as the quality of the
Fund's accounting principles and internal controls) required to be discussed by
Statement on Auditing Standards No. 61; and (iii) previously received written
confirmation from PwC that it is independent and written disclosures regarding
such independence as required by Independence Standards Board Standard No. 1,
and discussed with PwC the auditors' 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 auditors.
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 on the review and discussions referred to in items (i) through
(iii) above, the Audit Committee recommended to the Board of Trustees (and the
Board has approved) that the audited financial statements be included in the
Fund's annual report for the Fund's fiscal year ended July 31, 2004 and that PwC
be appointed as the Fund's independent auditors for the fiscal year ending July
31, 2005.

                                   Submitted by the Audit Committee
                                   of the Fund's Board of Trustees

                                   Jerry Rosenbloom, Chairperson
                                   Mark Jurish
                                   Ronald A. Nyberg
                                   Ronald E. Toupin, Jr.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Each Trustee and certain officers of the Fund, MBIA-CMC, certain
affiliated persons of MBIA-CMC and persons who own more than 10% of any class of
outstanding equity securities of the Fund are required to file forms reporting
their affiliation with the Fund and reports of ownership and changes in
ownership with the Securities and Exchange Commission (the "SEC") and the New
York Stock Exchange. These persons and entities are required by SEC regulation
to furnish the Fund with copies of all such forms they file. Based solely on a
review of those forms furnished to the Fund, the Fund believes that the Fund's
Trustees, and relevant officers, MBIA-CMC and relevant affiliated persons of
MBIA-CMC have complied with all applicable filing requirements during the fiscal
year ended July 31, 2004.

REQUIRED VOTE

         Election of Messrs. Corso, Nyberg, Rosenbloom and Dalmaso to the Board
of Trustee of the Fund will require the affirmative vote of a majority of the
votes of the common shareholders and the preferred shareholders (voting together
as a single class) of the Fund cast for the election of Trustees at the Meeting,
in person or by proxy. Election of Messrs. Jurish and Toupin to the Board of
Trustees will require the affirmative vote of a majority of the votes of the
preferred shareholders (voting as a separate class) of the Fund, cast for the
election of Trustees at the Meeting, in person or by proxy.

         THE TRUSTEES, INCLUDING THE TRUSTEES WHO ARE NOT "INTERESTED PERSONS,"
UNANIMOUSLY RECOMMEND THAT THE SHAREHOLDERS VOTE "FOR" THE NOMINEES FOR TRUSTEE.

INDEPENDENT AUDITORS

         The Audit Committee of the Fund unanimously approved the appointment of
PwC as the Fund's independent auditors for the current fiscal year ending July
31, 2005. PwC is located at 300 Madison Avenue, New York, New York 10017.

         A representative of PwC, if requested by any shareholder, will be
present via telephone at the Meeting to respond to appropriate questions from
shareholders and will have an opportunity to make a statement if he or she
chooses to do so.

         The Fund's Audit Committee has adopted written policies relating to the
pre-approval of the audit and non-audit services performed by the Fund's
independent auditors. Unless a type of service to be provided by the independent
auditors has received general pre-approval, it requires specific pre-approval by
the Audit Committee. Under the policies, on an annual basis, the Fund's Audit
Committee reviews and pre-approves the services to be provided by the
independent auditors without having obtained specific pre-approval from the
Audit Committee. The Audit Committee has delegated pre-approval authority to the
Audit Committee Chairperson. In addition, the Audit Committee pre-approves any
permitted non-audit services to be provided by the independent auditors to
MBIA-CMC or any entity controlling, controlled by, or under common control with
MBIA-CMC (MBIA-CMC and such other entities, together, the "Service Affiliates")
if such services related directly to the operations and financial reporting of
the Fund.

         AUDIT FEES. Audit Fees are fees related to the annual audit of the
Fund's financial statements and for services normally provided in connection
with the statutory and regulatory filings of the Fund. These fees also include
non-recurring fees billed to the Fund by PwC in connection with the initial
public offering of common shares of the Fund. For the initial fiscal year ended
July 31, 2004, PwC billed $58,000 to the Fund, including out of pocket expenses.

         AUDIT-RELATED FEES. Audit-Related Fees are fees related to assurance
and related services related to the annual audit of the Fund and for review of
the Fund's financial statements, other than the Audit Fees described above.
These include agreed upon procedures reports performed for rating agencies and
the issuance of comfort letters. Audit-Related Fees billed by PwC to the Fund
for the initial fiscal year ended July 31, 2004 were $46,500. PwC did not bill
any Audit-Related Fees to the Service Affiliates for audit-related services
related directly to the operations and financial reporting of the Fund for the
Fund's initial fiscal year ended July 31, 2004.

         TAX FEES. Tax Fees, which are fees associated with tax compliance, tax
advice and tax planning, including federal, state and local income tax return
preparation and related advice and determination of taxable income and
miscellaneous tax advice, rendered by PwC to the Fund for the initial fiscal
year ended July 31, 2004 were $8,000. PwC did not bill any Tax Fees to the
Service Affiliates for tax services related directly to the operations and
financial reporting of the Fund for the Fund's initial fiscal year ended July
31, 2004.

         ALL OTHER FEES. All Other Fees are fees related to products and
services other than those services reported above under "Audit Fees,"
"Audit-Related Fees" and "Tax Fees". There were no All Other Fees billed by PwC
to the Fund or the Service Affiliates for the initial fiscal year ended July 31,
2004.

         AGGREGATE NON-AUDIT FEES. The Aggregate Non-Audit Fees billed by PwC

2004 were $54,500, consisting of $46,500 Audit-Related Fees and $8,000 Tax Fees.

Affiliates for the initial fiscal year ended July 31, 2004.

year ended July 31, 2004, were approved pursuant to the de minimis exception
provided in Rule 2-01(c)(7)(i)(C) of Regulation S-X promulgated by the SEC.

 PROPOSALS TO BE SUBMITTED BY SHAREHOLDERS AND OTHER SHAREHOLDER COMMUNICATIONS

         All proposals by shareholders of the Fund which are intended to be
presented at the Fund's next annual meeting of shareholders to be held in 2005
must be received by the Fund for inclusion in the Fund's proxy statement and
proxy relating to that meeting no later than June 1, 2005. The submission by a
shareholder of a proposal for inclusion in the proxy materials does not
guarantee that it will be included. Shareholder proposals are subject to certain
requirements under the federal securities laws. In order for proposals made
outside of Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act") to be considered "timely" within the meaning of Rule 14a-4(c)
under the Exchange Act, such proposal must be received by the Fund no later than

should also deliver such communications to the Secretary of the Fund at the

counsel, and other advisers as appropriate, which shareholder communications
will be relayed to the Board.

     MBIA CAPITAL/CLAYMORE MANAGED DURATION INVESTMENT GRADE MUNICIPAL FUND

                            AUDIT COMMITTEE CHARTER

I.       MEMBERSHIP AND QUALIFICATIONS

         A.  The Audit Committee of MBIA Capital/Claymore Managed Duration
             Investment Grade Municipal Fund (the "Fund") shall be composed
             entirely of directors who are not "interested persons" of the Fund,
             as defined in the Investment Company Act of 1940, as amended, and
             as required under Section 303A of the New York Stock Exchange
             Listed Company Manual. The Audit Committee shall consist of not
             fewer than three (3) of such directors. The Board of Trustees of

             at any time in its sole discretion.

         B.  Each member of the Audit Committee must be financially literate, as
             that qualification is interpreted by the Board in its business
             judgment, or must become financially literate within a reasonable
             time after appointment to the Audit Committee. At least one member
             of the Audit Committee must have accounting or related financial
             management expertise as the Board interprets such qualification in
             its business judgment.

             Committee is an "audit committee financial expert" as defined in
             Item 3 of Form N-CSR.

II.      FUNCTION AND PURPOSES

         A.  The function of the Audit Committee is oversight. It is
             management's responsibility to maintain appropriate systems for

             responsibility to plan and carry out a proper audit.

         B.  The independent auditors for the Fund shall report directly to the
             Audit Committee.

         C.  The purposes of the Audit Committee are:

             (1)  to oversee the Fund's accounting and financial reporting
                  policies and practices and its internal controls over
                  financial reporting and, as the Audit Committee deems
                  appropriate, to inquire into the internal controls over
                  financial reporting of certain third-party service providers;

             (2)  to oversee the quality, integrity and objectivity of the
                  Fund's financial statements and the independent audit thereof;

             (3)  to approve prior to appointment the engagement of the Fund's
                  independent auditors;

             (4)  to act as liaison between the Fund's independent auditor and
                  the Board;

                  independent auditor;

                  the Fund's financial statements; (2) the Fund's compliance
                  with legal and regulatory requirements; (3) the independent
                  auditor's qualifications and independence; and (4) the
                  performance of the Fund's internal audit function and of its
                  independent auditor;

             (7)  to prepare an audit committee report as required by the
                  Securities Exchange Commission, to be included in the Fund's
                  annual proxy statement;

             (8)  to, at least annually, obtain and review a report by the
                  independent auditor describing (1) the firm's internal
                  quality-control procedures; (2) any material issues raised by
                  the most recent internal quality-control review, or peer
                  review, of the firm, or by any inquiry or investigation by
                  governmental or professional authorities, within the preceding
                  five (5) years, respecting one or more independent audits
                  carried out by the firm, and any steps taken to deal with any
                  such issues; and (3) to assess the independent auditor's
                  independence with regard to all relationships between the
                  independent auditor and the Fund;

                                       A-1



             (9)  to discuss the Fund's annual audited financial statements and
                  semi-annual financial statements with management and the
                  independent auditor;

             (10) to discuss the Fund's earnings press releases, financial
                  information and earnings guidance provided to analysts and

             (11) to discuss policies with respect to risk assessment and risk

                  internal audit function) and with the independent auditor;

             (13) to review with the independent auditor any audit problems or
                  difficulties and management's responses to the same;

             (14) to set clear hiring policies for the Fund as regards the
                  hiring of employees or former employees of the independent
                  auditor; and

             (15) to report regularly to the Board.

         D.  To carry out its purposes, the Audit Committee shall have the
             following duties and powers:

             (1)  to select, retain and terminate the Fund's independent auditor
                  and, in connection therewith, to evaluate the independence of
                  the independent auditor, including whether the independent
                  auditor provides any consulting services to the Fund, and to
                  receive the independent auditor's specific representations as
                  to its independence. In evaluating the auditor's
                  qualifications, performance and independence, the Audit
                  Committee must, among other things, obtain and review a report
                  by the auditor, at least annually, describing the following
                  items:

                  (a) all relationships between the independent auditor and the
                      Fund, as well as the Fund's investment adviser or any
                      control affiliate of the adviser that provides ongoing
                      services to the Fund;

                  (b) any material issues raised by the most recent internal

                      professional authorities, within the preceding five years,
                      respecting one or more independent audits carried out by
                      the firm, and any steps taken to deal with any such

                  auditor's comments with respect to the Fund's financial
                  policies, procedures and internal accounting controls and

                  annual performance evaluation of the Audit Committee;

             (3)  to review and approve the fees charged by the auditors for
                  audit and non-audit services;

             (6)  to engage independent counsel and other advisers, as the Audit

     MBIA CAPITAL/CLAYMORE MANAGED DURATION INVESTMENT GRADE MUNICIPAL FUND

                          NOMINATING COMMITTEE CHARTER

ORGANIZATION AND GOVERNANCE

The Nominating Committee (the "Committee") of MBIA Capital/Claymore Managed
Duration Investment Grade Municipal Fund (the "Fund") shall be comprised solely
of Trustees who are not "interested persons" of the Fund as defined in Section

who are "independent" as such term is defined in the New York Stock Exchange
listing standards (the "Independent Trustees").

The Committee shall be comprised of as many Independent Trustees as the Board of
Trustees of the Fund (the "Board") shall determine, but in any event not fewer
than three (3) members, each of whom shall serve for a term of one year which
shall be extendable at the sole discretion of the Board. The Board may remove or

STATEMENT OF PURPOSES AND RESPONSIBILITIES

The Committee shall select and nominate persons for election as Trustees of the

(iii) to set any necessary standards or qualifications for service as a Trustee
of the Fund.

IDENTIFICATION AND EVALUATION OF POTENTIAL NOMINEES

The Committee may take into account a wide variety of factors in considering
Trustee nominees. In identifying and evaluating an individual as a potential
nominee to serve as a Trustee, or in evaluating whether to remove an incumbent
Trustee, the Committee shall consider among other factors it may deem relevant:

         o   whether or not the individual is an "interested person" as defined
             in the 1940 Act and whether the person is otherwise qualified under
             applicable laws and regulations to serve as a Trustee or
             Independent Trustee of the Fund;

         o   whether or not the individual has any relationships that might
             impair his or her independence, such as any business, financial or
             family relationships with Fund management, the investment manager
             of the Fund, Fund service providers or their affiliates;

         o   whether or not the individual serves on boards of, or is otherwise
             affiliated with, competing financial service organizations or their
             related mutual fund complexes;

         o   whether or not the individual is willing to serve, and willing and
             able to commit the time necessary for the performance of the duties
             of a Trustee of the Fund;

         o   the contribution the individual can make to the Board and the Fund,
             with consideration being given to the individual's educational
             background and business and professional experience;

         o   the character and integrity of the individual; and

         o   the overall diversity of the Board's composition.

         o   The Committee may, but is not required to, retain a third-party
             search firm at the Fund's expense to assist in the identification
             of Independent Trustee nominees.

                                       B-1



CONSIDERATION OF NOMINEES RECOMMENDED BY STOCKHOLDERS

While the Committee is solely responsible for the selection and nomination of
the Fund's Trustees, the Committee shall accept nominations for the office of
Trustee made by Fund stockholders on the same basis as it considers and
evaluates nominees recommended by other sources. Stockholders who wish to
recommend a nominee should send nominations to the Secretary of the Fund which
include biographical information and set forth the qualifications of the
proposed nominee.

QUORUM

A majority of the members of the Committee shall constitute a quorum, and the
act of a majority of the members of the Committee present at any meeting at
which there is quorum present shall be the act of the Committee.
