SEMI-ANNUAL REPORT

June 30, 2008

(THIS PAGE INTENTIONALLY LEFT BLANK)

TCW Strategic Income Fund, Inc.

THE PRESIDENT'S LETTER

Dear Shareholder:

We are pleased to present the 2008 semi-annual report of the TCW Strategic Income Fund, Inc. ("TSI" or "the Fund"). TSI is a multi-asset class closed-end fund managed by TCW Investment Management Company. The Fund's current distribution policy is to pay at least 7% annually based on previous year-end net asset value ("NAV"). During the first half of 2008, two quarterly dividends of $0.075 per share were paid out. The dividends were paid entirely from income earned by the Fund through June 30th. The overall return of the Fund's NAV during the first half of 2008 was 0.4% (with dividends invested). The NAV discount to market price narrowed from 14.1% at the end of the 2007 to 11.8% at June 2008. The custom index for the Fund, a blend of equity and fixed income indices, was down 2.2% during the first six months of 2008.

TSI's underlying asset allocation includes a mix of fixed income and equity securities. While most of these asset classes did not make positive contributions to the performance of the Fund NAV during the first half of 2008, the largest allocation of the Fund, to Mortgage-Backed Securities ("MBS"), had strong performance, offsetting losses in other areas. However, negative absolute equity performance and the impact of the continuing credit crisis had an impact on the Fund performance. In particular, prices for Collateralized Debt Obligation ("CDO") and Asset-Backed Security ("ABS") holdings in the Fund were marked down significantly as these markets continued to experience delinquencies in underlying collateral pools and rating downgrades. Market liquidity for these types of securities continues to be weak with distressed pricing.

The following table summarizes the performance of the seven principal market sectors included in the Fund during the first six months of 2008:

Sector |  | Market Value |  | Fund Allocation |  | Sector Return (Gross of Fees) |
Mortgage- Backed Securities |  | $ | 176.7 |  |  |  | 71.5 | % |  |  | 11.5 | % |
Convertible Securities |  |  | 21.0 |  |  |  | 8.5 |  |  |  | -4.8 | % |
Collateralized Debt Obligations |  |  | 17.1 |  |  |  | 7.0 |  |  |  | -17.6 | % |
High Yield Debt |  |  | 18.1 |  |  |  | 7.3 |  |  |  | -2.4 | % |
Common Stocks |  |  | 7.7 |  |  |  | 3.1 |  |  |  | -16.4 | % |
Preferred Stocks |  |  | 4.7 |  |  |  | 1.9 |  |  |  | -4.2 | % |
Asset-Backed Securities |  |  | 1.8 |  |  |  | 0.7 |  |  |  | -56.6 | % |
|  | $ | 247.1 |  |  |  | 100.0 | % |  |  |  |  |

The above portfolio composition was the result of the following allocation decisions:

• Since the Fund's exposure to the ABS sector was very low during the period due to previous period writedowns, the negative performance reported by this allocation had only a small impact on the overall Fund NAV performance.

• The Fund's CDO allocation is now essentially all in the form of Collateralized Loan Obligations ("CLO") with exposure to collateral composed of bank and commercial real estate loans. These securities have also been repriced lower during the quarter with negative performance. Two CLO positions were sold at a price close to the then current mark-to-market values. The investment team is looking for other opportunities to reduce exposure at reasonable values.

• The Fund's exposure to High Yield via synthetic exposure to the CDX index was trimmed in half

TCW Strategic Income Fund, Inc.

THE PRESIDENT'S LETTER (CONT'D)

during the first half of 2008 with the proceeds reinvested in MBS, an operation that added value.

• The Fund has a small allocation to equities which underperformed the S&P 500 Index and was negative in absolute terms. The exposure to equities was strategically reduced more than one year ago.

• The Fund's exposure to MBS has increased from approximately 50% to an over 70% allocation due to relative market action and strategic and tactical moves funded by trimming other asset classes and deploying Fund leverage. This reallocation added value during the first half of 2008 as the MBS component of the Fund had positive performance and exceeded the Lehman Aggregate Index by a wide margin. This allocation is composed of MBS with high credit ratings, including those backed by mortgages securitized by Government Sponsored Enterprises ("GSEs") as well as through private channel issuance. Some securities have characteristics that differ from traditional passthrough MBS, including their liquidity and sensitivity to rate changes. These securities include inverse floaters and interest-only securities. The non-GSE-backed MBS securities have greater exposure to credit risk, although we have purchased these with a view to capturing the opportunities from pricing pressures they currently are experiencing, relative to our assessment of their default risks. Currently, the MBS tranche has minimal underlying exposure to lower-rated real estate borrowers (FICO score less than 650) and carries a minimum individual security rating of A and an average rating of AAA/Agency.

• The Fund started the year with $4.5 million in leverage and had $48.2 million at the end of June 2008.

We are comfortable with how these decisions have positioned the Fund portfolio during the first half of 2008. The strong performance of MBS since the increased allocation to that sector has been very favorable for the Fund year to date. We also would note that TSI has the discretion to use borrowed funds at a cost of 75 basis points over the Fed Funds rate to leverage the portfolio. During the first half of the year, the Fund continued to increase leverage to invest primarily in MBS. The Fund as of today is benefiting from positive cash-flow carry on those positions.

There has been a change to the TSI Board of Directors and executive management. I was appointed as President and Chief Executive Officer, replacing Mr. William C. Sonneborn, who announced his departure from TCW this month. I personally would like to thank Mr. Sonneborn for his extraordinary service and dedication to the Fund.

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

Sincerely,

Ronald R. Redell
President and Chief Executive Officer

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 and is traded on the New York Stock Exchange under the symbol TSI. 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. TCW Investment Management Company (the "Advisor") is the Investment Advisor to the Fund and is registered under the Investment Advisors Act of 1940.

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.

The Fund values asset-backed securities and collateralized debt obligations securities with valuations provided by dealers who make markets in such securities. The Schedule of Investments includes investments with a value of $18,923,111 or 9.6% of net assets whose values have been determined based on prices supplied by dealers in the absence of readily determinable values. These values may differ from the realizable values had a liquid market existed for these investments, and the differences could be material.

The Fund invests a portion of its assets in below-investment grade debt securities, including asset-backed securities and collateralized debt obligations. The value and related income of these securities is sensitive to changes in economic conditions, including delinquencies and/or defaults. Recent instability in the markets for fixed-income securities, particularly securities with sub-prime exposure, has resulted in increased volatility of market prices and periods of illiquidity that have adversely impacted the valuation of certain securities held by the Fund.

Securities for which market quotations are not readily available, including circumstances under which it is determined by the Advisor that sale or mean prices are not reflective of a security's market value, are

valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Company's Board of Directors. At June 30, 2008, two securities were fair valued at $1,723,355 or 0.9% of net assets.

The Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), effective January 1, 2008. In accordance with FAS 157, fair value is defined as the price that the Fund would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. FAS 157 established a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value including such a pricing model and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below.

Level 1—quoted prices in active markets for identical investments

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

Level 3—significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

The following is a summary of the inputs used as of June 30, 2008 in valuing the Fund's investments:

Valuation Inputs |  | Investments in Securities |
Level 1—Quoted Prices |  | $ | 20,699,826 |  |
Level 2—Other Significant Observable Inputs |  |  | 216,594,395 |  |
Level 3—Significant Unobservable Inputs |  |  | 18,923,111 |  |
Total |  | $ | 256,217,332 |  |

Following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining value:

|  | Investments in Securities |
Balance as of 12/31/07 |  | $ | 33,493,021 |  |
Accrued discounts/premiums |  |  | 14,137 |  |

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONT'D)

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.

For certain lower credit quality securitized assets that have contractual cash flows (for example, asset-backed securities, collateralized mortgage obligations and commercial mortgage-backed securities) but the cash flows have changed based on an evaluation of current information, then the estimated yield is adjusted on a prospective basis over the remaining life of the security.

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, 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, 2008, net unrealized appreciation for federal income tax purposes is comprised of the following components:

Appreciated securities |  | $ | 19,977,972 |  |
Depreciated securities |  |  | (58,370,168 | ) |
Net unrealized appreciation |  | $ | (38,392,196 | ) |
Cost of securities for federal income tax purposes |  | $ | 294,609,528 |  |

The Fund is subject to the provisions of Financial Accounting Standards Board Interpretation No. 48 ("FIN 48") "Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement

23

TCW Strategic Income Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONT'D)

No. 109". FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The Fund did not have any unrecognized tax benefits at June 30, 2008, nor were there any increases or decreases in unrecognized tax benefits for the period then ended. The Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as an income tax expense in the Statement of Operations. During the period ended June 30, 2008, the Fund did not incur any such interest or penalties. The Fund is subject to examination by U.S. federal and state tax authorities for returns filed for the prior three fiscal years.

Note 3—Investment Advisory and Service Fees:

As compensation for the services rendered, facilities provided, and expenses borne, the Advisor is paid a monthly fee by the Fund computed at the annual rate of 0.75% of the first $100 million of the Fund's average managed assets and 0.50% of the Fund's average managed assets in excess of $100 million.

In addition to the management fees, the Fund reimburses, with approval by the Fund's Board of Directors, a portion of the Advisor's costs associated in support of the Fund's Rule 38a-1 compliance obligations, which is included in the Statement of Operations.

Note 4—Purchases and Sales of Securities:

For the six months ended June 30, 2008, purchases and sales or maturities of investment securities (excluding short-term investments) aggregated $95,090,445 and $68,489,059, respectively, for non-U.S. Government Securities and aggregated $25,808,014 and $4,222,076, respectively, for U.S. Government Securities.

Note 5—Security Lending:

During the six months ended June 30, 2008, the Fund lent securities to brokers. The brokers provided cash as collateral, which must be maintained at not less than 100% of the value of the loaned securities, to secure the obligation. At June 30, 2008, the cash collateral received from borrowing brokers was $8,832,624, which was 102.53% of the value of loaned securities. The Fund receives income, net of broker fees, by investing the cash collateral in short-term investments and is stated on the Statement of Operations.

Note 6—Directors' Fees:

Directors who are not affiliated with the Advisor received, as a group, fees and expenses of $38,239 from the Fund for the six months ended June 30, 2008. Certain Officers and/or Directors of the Fund are also Officers and/or Directors of the Advisor.

Note 7—Restricted Securities:

The Fund is permitted to invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. There were no restricted securities (excluding 144A issues) at June 30, 2008. However, certain 144A securities were deemed illiquid as of June 30, 2008 and therefore were considered restricted. Aggregate cost and fair value of such securities held at June 30, 2008 were as follows:

|  | Aggregate Cost |  | Aggregate Value |  | Value as a Percentage of Fund's Net Assets |
Total of Restricted Securities |  | $ | 41,841,870 |  |  | $ | 16,664,973 |  |  |  | 8.4 | % |

Note 8—Loan Outstanding:

The Fund is permitted to have bank borrowings for investment purposes. The Fund has entered into a line of credit agreement with The Bank of New York Mellon which permits the Fund to borrow up to $60 million at a rate, per annum, equal to the Federal Funds Rate plus 0.75%. The average daily loan balance during the period for which loans were outstanding amounted to $42,931,318, and the weighted average interest rate was 3.19%. Interest expense for the line of credit was $681,354 for the six months ended June 30, 2008. The maximum outstanding loan balance during the six months ended June 30, 2008 was $59,600,000. The outstanding loan balance at June 30, 2008 was $48,200,000.

Note 9—Indemnifications:

Under the Fund's organizational documents, its officers and Directors may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Fund, and shareholders are indemnified against personal liability for the obligations of the Fund. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote. The Fund has not accrued any liability in connection with such indemnification.

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 12, 2008, 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, including other pooled investment vehicles and registered investment companies. 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 senior management and portfolio management 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 and its compensation program. 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 including the Advisor's participation in the SEC pilot examination program. In this regard, the Board noted the significant efforts of the Advisor's compliance staff in administering the Fund's compliance program and took into consideration the assessment by the Fund's Chief Compliance Officer. 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 information

APPROVAL OF ADVISORY AND MANAGEMENT AGREEMENT (CONT'D)

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 to the Fund in the Report. The Board noted that although the Fund underperformed in 2007, it met its income target. The Board also noted that the Advisor made personnel changes with respect to the Fund's management. 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 fee 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.
