SEMI-ANNUAL REPORT

TCW Strategic Income Fund, Inc.

THE PRESIDENT'S LETTER

Dear Shareholder:

We are pleased to present the 2007 semi-annual report of the TCW Strategic Income Fund, Inc. ("TSI" or "the Fund"). TSI is a multi-asset class closed-end fund with a 75% fixed income and 25% equity asset allocation at June 30, 2007. The fixed income portfolio consists of collateralized debt obligation equity, high yield, asset-backed and mortgage-backed securities, while the equity portfolio consists of convertible and large cap value securities. The Fund had a modest leverage position represented by $16.4 million of borrowings at June 30, 2007. As of July 25, 2007, the Fund had no leverage. In October 2004, the Board of Directors approved a managed distribution plan which pays a minimum of 7% of the Fund's net asset value ("NAV") based on the prior year-end NAV. Based on this policy, the Fund will pay a minimum of 39 cents per share in 2007.

The mortgage-backed securities orientation of the fixed income portfolio has made the first six months difficult for the Fund, as the sector has been under pressure because of the difficulties in the subprime area. For the six months ended June 30, 2007, including dividends reinvested, the Fund's shareholders realized a negative return of (2.14%) as the Fund's NAV declined (5.31%). The Fund's discount narrowed from 8.8% to 5.9% and the Fund declared two quarterly dividends totaling 19.6 cents. The negative returns are primarily the result of mark-to-market price declines in the Fund's asset-backed and collateralized debt obligation equity securities. The Fund held securities representing approximately 18% of total assets, which have some exposure to subprime mortgage loans and pricing for these securities has reached distressed levels with little liquidity in the marketplace. The Fund's investment policies do not require sales due to mark-to-market write-downs or rating changes on securities.

On behalf of the Board and everyone at TCW, I would like to thank you for your continued support. .

Very truly yours,

Alvin R. Albe, Jr.
President & Chief Executive Officer

July 25, 2007

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

Note 1—Significant Accounting Policies:

TCW Strategic Income Fund, Inc. (the "Fund") was incorporated in Maryland on January 13, 1987 as a diversified, closed-end investment management company and is registered under the Investment Company Act of 1940, as amended. The Fund commenced operations on March 5, 1987. The Fund's investment objective is to seek a total return comprised of current income and capital appreciation by investing in convertible securities, marketable equity securities, investment-grade debt securities, high-yield debt securities, options, securities issued or guaranteed by the United States Government, its agencies and instrumentalities ("U.S. Government Securities"), repurchase agreements, mortgage related securities, asset-backed securities, money market securities and other securities without limit believed by the Fund's investment advisor to be consistent with the Fund's investment objective.

The preparation of the accompanying financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

The following is a summary of the significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America.

Security Valuation: Securities traded on national exchanges are valued at the last reported sales price or the mean of the current bid and asked prices if there are no sales in the trading period. Other securities which are traded on the over-the-counter market are valued at the mean of the current bid and asked prices. Short-term debt securities with maturities of 60 days or less at the time of purchase are valued at amortized cost. Other short-term debt securities are valued on a mark-to-market basis until such time as they reach a remaining maturity of 60 days, where upon they will be valued at amortized value using their value of the 61st day prior to maturity.

Security Transactions and Related Investment Income: Security transactions are recorded on the trade date. Dividend income is recorded on the ex-dividend date, while interest income is recorded on the accrual basis. Discounts, including original issue discounts, and premiums on securities purchased are amortized using a constant yield-to-maturity method. Realized gains and losses on investments are recorded on the basis of specific identified cost.

Distributions: Distributions to shareholders are recorded on ex-dividend date. The Fund declares and pays, or reinvests, dividends quarterly based on the managed distribution plan adopted by the Fund's Board of Directors. Under the Plan, the Fund will distribute a cash dividend equal to 7% of the Fund's net asset value on an annualized basis. The distribution will be based on the Fund's net asset value from the previous calendar year-end. The source for the dividend comes from net investment income and net realized capital gains measured on a fiscal year basis. Any portion of the distribution that exceeds income and capital gains will be treated as a return of capital. Under certain conditions (which the Fund presently meets), federal tax regulations cause some or all of the return of capital to be taxed as ordinary income. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences may be primarily due to differing treatments for market discount and premium, losses deferred due to wash sales and spillover distributions. Permanent book and tax basis differences relating to shareholder distributions will result in

reclassifications to paid-in capital and may affect net investment income per share.

Repurchase Agreements: The Fund may invest in repurchase agreements secured by U.S. Government Securities. A repurchase agreement arises when the Fund purchases a security and simultaneously agrees to resell it to the seller at an agreed-upon future date. The Fund requires the seller to maintain the value of the securities, marked to market daily, at not less than the repurchase price. If the seller defaults on its repurchase obligation, the Fund could suffer delays, collection expenses and losses to the extent that the proceeds from the sale of the collateral are less than the repurchase price.

Note 2—Federal Income Taxes:

It is the policy of the Fund to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and distribute all of its net taxable income, including any net realized gains on investments, to its shareholders. Therefore, no federal income tax provision is required.

At June 30, 2007, net unrealized appreciation for federal income tax purposes is comprised of the following components:

Appreciated securities |  | $ | 6,361,627 |  |
Depreciated securities |  |  | (26,762,734 | ) |
Net unrealized appreciation |  | $ | (20,401,107 | ) |
Cost of securities for federal Income tax purposes |  | $ | 335,322,394 |  |

The Fund adopted Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN No. 48"), Accounting for Uncertainty in Income Taxes, during the six months ended June 30, 2007. The adoption of FIN No. 48 did not have a material effect on the net asset value, financial condition or results of operations of the Fund, as there was no liability for unrecognized tax benefits and no change to the beginning net asset value of the Fund. As of and during the six months ended June 30, 2007, the Fund did not have a liability for any unrecognized tax benefits.

The Fund is subject to examination by U.S. federal and state tax authorities for returns filed after 2004 and 2003, respectively.

Note 3—Investment Advisory and Service Fees:

TCW Investment Management Company (the "Advisor") is the investment advisor to the Fund.

APPROVAL OF ADVISORY AND MANAGEMENT AGREEMENT

TCW Strategic Income Fund, Inc. (the "Fund") and TCW Investment Management Company (the "Advisor") are parties to an Investment Advisory and Management Agreement ("Advisory Agreement"), pursuant to which the Advisor is responsible for managing the investments of the Fund. At a meeting held on May 7, 2007, the Board of Directors of the Fund re-approved the Advisory Agreement. The full Board of Directors, including the Independent Directors, considered the sufficiency of the information provided to assist them in their review of the Advisory Agreement and made assessments with respect to the Advisory Agreement. The Advisor provided materials to the Board for its evaluation, and the Independent Directors were advised by independent legal counsel with respect to these and other relevant matters. The Independent Directors requested information from the Advisor, reviewed the material and determined that the material received was sufficient to allow the Board to make a determination regarding the Advisory Agreement. Discussed below are the factors considered by the Board in approving the Advisory Agreement. This discussion is not intended to be all-inclusive. The Board reviewed a variety of factors and considered a significant amount of information, including information received on an ongoing basis at Board and committee meetings. The approval determination was made on the basis of each Director's business judgment after consideration of all the information taken as a whole. Individual Directors may have given different weight to certain factors and assigned various degrees of materiality to information received in connection with the contract review process.

In evaluating the Advisory Agreement, the Board of Directors, including the Independent Directors, considered the following factors, among others:

• Nature, Extent and Quality of Services. The Board considered the benefits to shareholders of continuing to retain the Advisor as the investment advisor to the Fund, particularly in light of the nature, extent, and quality of services provided by the Advisor. The Board evaluated the Advisor's experience in serving as manager of the Fund noting that the Advisor serves a variety of other investment advisory clients. The Board considered the benefit to shareholders of a fund that is part of a larger organization that provides investment advisory services to mutual funds, separate accounts, commingled funds and collective trusts. The Board also considered the ability of the Advisor to provide an appropriate level of support and resources to the Fund and whether the Advisor has sufficiently qualified personnel. The Board noted the background and experience of the Advisor's senior management and portfolio management personnel, and that the management expertise and amount of attention expected to be given to the Fund by the Advisor is substantial. The Board considered the Advisor's ability to attract and retain qualified business professionals. The Board also considered the breadth of the Advisor's compliance program as well as the Advisor's compliance operations with respect to the Fund. In this regard, the Board noted the significant efforts of the Advisor's compliance staff in administering the Fund's compliance program. The Board concluded that it was satisfied with the nature, extent and quality of the investment management services anticipated to be provided to the Fund by the Advisor under the Advisory Agreement.

• Investment Performance. The Board was provided with a report prepared by an independent third-party consultant (the "Report"), which provided a comparative analysis of the performance of the Fund to similar funds, including the short- and long-term performance of the Fund. The Board reviewed

25

TCW Strategic Income Fund, Inc.

APPROVAL OF ADVISORY AND MANAGEMENT AGREEMENT (CONT'D)

information in the Report regarding the performance and expense levels of the Fund as compared to other funds in its peer group and category, and considered the rankings given the Fund in the Report. The Board noted that because the Fund changed its investment policies in 2006 it had less than one year of relative comparative performance. The Board concluded that the Advisor should continue to provide investment management services to the Fund consistent with its objectives and strategy.

• Reasonableness of Advisory Fees and Profitability. The Board considered information in the Report and in materials prepared by the Advisor regarding the advisory fees charged under other investment advisory contracts with the Advisor and other investment advisers for other registered investment companies or other types of clients, as well as the total expenses of the Fund. The Board noted that the Advisor does not manage any separate accounts in a manner substantially similar to the current strategy of the Fund. The Board also noted that the management fee charged to the Fund was lower than the median management fee charged to funds in its category as presented in the Report and that the Fund's expenses were lower than the median expenses of the funds in the Fund's category. The Board also considered the cost of services to be provided and profits to be realized by the Advisor and its affiliates from the relationship with the Fund, including the overall financial soundness of the Advisor. The Board reviewed profitability information provided by the Advisor. The Board recognized the difficulty in evaluating a manager's profitability with respect to the Fund in the context of a manager with multiple lines of business and noted that other profitability methodologies may be reasonable. Based on their evaluation of this information, the Board concluded that the contractual management fee of the Fund under the Advisory Agreement is fair and bears a reasonable relationship to the services rendered.

• Economies of Scale. The Board considered the potential of the Advisor to experience economies of scale as the Fund grows in size. The Board noted that the Fund currently has a relatively low asset size and that, as a closed-end fund, there is limited potential for the Fund to experience significant asset growth other than through capital appreciation and income production. The Board noted the Advisory Agreement has a breakpoint. On this basis, the Board concluded that the current fee structure reflected in the Advisory Agreement is appropriate.

• Ancillary Benefits. The Board considered ancillary benefits to be received by the Advisor and its affiliates as a result of the Advisor's relationship with the Fund, including commission practices (such as soft dollars) and compensation for certain compliance support services. The Board noted that, in addition to the fees the Advisor received under the Advisory Agreement, the Advisor could receive additional benefits from the Fund in the form of reports, research and other services obtainable from brokers and their affiliates in return for brokerage commissions paid to such brokers. The Board concluded that any potential benefits to be derived by the Advisor from its relationship with the Fund are consistent with the services provided by the Advisor to the Fund.

After consideration of these factors, the Board (i) concluded that the compensation payable under the Advisory Agreement is fair and bears a reasonable relationship to the services rendered and that the renewal of the Agreement would be in the best interests of the Fund and its shareholders, and (ii) approved the renewal of the Advisory Agreement for an additional one-year period subject to the terms of the Agreement.
