UNDERSTANDING YOUR FUND’S EXPENSES (Unaudited)

As a mutual fund investor, you pay ongoing expenses, such as management fees and other expenses. Using the information below, you can estimate how these expenses affect your investment and compare them with the expenses of other funds. You also may pay one-time transaction expenses, including sales charges (loads) and redemption fees, which are not shown in this section and would have resulted in higher total expenses. For more information, see your fund’s prospectus or talk to your financial adviser.

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in Dreyfus Treasury and Agency Liquidity Money Market Fund from June 1, 2022 to November 30, 2022. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses.

COMPARING YOUR FUND’S EXPENSES WITH THOSE OF OTHER FUNDS (Unaudited)

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (“SEC”) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds. All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

FINANCIAL HIGHLIGHTS

The following table describes the performance for the fiscal periods indicated. Net asset value total return is calculated assuming an initial investment made at the net asset value at the beginning of the period, reinvestment of all dividends and distributions at net asset value during the period, and redemption at net asset value on the last day of the period. Net asset value total return includes adjustments in accordance with accounting principles generally accepted in the United States of America and as such, the net asset value for financial reporting purposes and the returns based upon those net asset values may differ from the net asset value and returns for shareholder transactions. These figures have been derived from the fund’s financial statements.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Treasury and Agency Liquidity Money Market Fund (the “fund”) is the sole series of Dreyfus Institutional Liquidity Funds (the “Trust”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified open-end management investment company. The fund’s investment objective is to seek as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. The fund is managed by Dreyfus, a division of BNY Mellon Investment Adviser, Inc. (the “Adviser”), the fund’s investment adviser and a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”). BNY Mellon Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Adviser, is the distributor of the fund’s shares, which are sold to the public without a sales charge.

Effective May 2, 2022, “Dreyfus Cash Investment Strategies” was renamed “Dreyfus”.

The fund operates as a “government money market fund” as that term is defined in Rule 2a-7 under the Act. It is the fund’s policy to maintain a constant net asset value (“NAV”) per share of $1.00 and the fund has adopted certain investment, portfolio valuation and dividend and distribution policies to enable it to do so. There is no assurance, however, that the fund will be able to maintain a constant NAV per share of $1.00.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund is an investment company and applies the accounting and reporting guidance of the FASB ASC Topic 946 Financial Services-Investment Companies. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The Trustenters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown. The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: Investments in securities are valued at amortized cost in accordance with Rule 2a-7 under the Act. If amortized cost is

9

NOTES TO FINANCIAL STATEMENTS (continued)

determined not to approximate fair market value, the fair value of the portfolio securities will be determined by procedures established by and under the general oversight of the Trust’s Board of Trustees (the “Board”).

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value. This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements. These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted 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 inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For example, money market securities are valued using amortized cost, in accordance with rules under the Act. Generally, amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, such securities are reflected within Level 2 of the fair value hierarchy.

The following is a summary of the inputs used as of November 30, 2022in valuing the fund’s investments:

10

	Level 1-Unadjusted Quoted Prices	Level 2- Other Significant Observable Inputs	Level 3-Significant Unobservable Inputs	Total
Assets ($)
Investments in Securities:†
Short-Term Investments	-	7,870,845,595	-	7,870,845,595

^†See Statement of Investments for additional detailed categorizations, if any.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Interest income, adjusted for accretion of discount and amortization of premium on investments, is earned from settlement date and is recognized on the accrual basis. Realized gains and losses from securities transactions are recorded on the identified cost basis.

The fund may enter into repurchase agreements with financial institutions, deemed to be creditworthy by the Adviser, subject to the seller’s agreement to repurchase and the fund’s agreement to resell such securities at a mutually agreed upon price. Pursuant to the terms of the repurchase agreement, such securities must have an aggregate market value greater than or equal to the terms of the repurchase price plus accrued interest at all times. If the value of the underlying securities falls below the value of the repurchase price plus accrued interest, the fund will require the seller to deposit additional collateral by the next business day. If the request for additional collateral is not met, or the seller defaults on its repurchase obligation, the fund maintains its right to sell the underlying securities at market value and may claim any resulting loss against the seller. The collateral is held on behalf of the fund by the tri-party administrator with respect to any tri-party agreement. The fund may also jointly enter into one or more repurchase agreements with other funds managed by the Adviser in accordance with an exemptive order granted by the SEC pursuant to section 17(d) and Rule 17d-1 under the Act. Any joint repurchase agreements must be collateralized fully by U.S. Government securities.

(c) Market Risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. The value of a security may also decline due to general market conditions that are not specifically related to a particular company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, changes to inflation, adverse changes to credit markets or adverse investor sentiment generally. In addition, turbulence in

11

NOTES TO FINANCIAL STATEMENTS (continued)

financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Recent examples include pandemic risks related to COVID-19 and aggressive measures taken world-wide in response by governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines of large populations, and by businesses, including changes to operations and reducing staff.

(d) Dividends and distributions to shareholders: It is the policy of the fund to declare dividends daily from net investment income. Such dividends are paid monthly. Dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”). To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains.

(e) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, if such qualification is in the best interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended November 30, 2022, the fund did not have any liabilities for any uncertain tax positions. The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period ended November 30, 2022, the fund did not incur any interest or penalties.

Each tax year in the four-year period ended November 30, 2022 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At November 30, 2022, the components of accumulated earnings on a tax basis were as follows: undistributed ordinary income $59,502 and accumulated capital losses $49,049.

12

The fund is permitted to carry forward capital losses for an unlimited period. Furthermore, capital loss carryovers retain their character as either short-term or long-term capital losses.

The accumulated capital loss carryover is available for federal income tax purposes to be applied against future netrealized capital gains, if any, realized subsequent to November 30, 2022. The fund has $49,049 of short-term capital losses which can be carried forward for an unlimited period.

The tax character of distributions paid to shareholders during the fiscal years ended November 30, 2022 and November 30, 2021 were all ordinary income.

At November 30, 2022, the cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes (see the Statement of Investments).

(f) New accounting pronouncements: In 2020, the FASB issued Accounting Standards Update No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting.

The objective of the guidance in Topic 848 is to provide temporary relief during the transition period. The FASB included a sunset provision within Topic 848 based on expectations of when the London Interbank Offered Rate (“LIBOR”) would cease being published. At the time that Update 2020-04 was issued, the UK Financial Conduct Authority (FCA) had established its intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022—12 months after the expected cessation date of all currencies and tenors of LIBOR.

In March 2021, the FCA announced that the intended cessation date of the overnight 1-, 3-, 6-, and 12-month tenors of USD LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848.

Because the current relief in Topic 848 may not cover a period of time during which a significant number of modifications may take place, the amendments in this Update defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024 (“FASB Sunset Date”), after which entities will no longer be permitted to apply the relief in Topic 848.

Management had evaluated the impact of Topic 848 on the fund’s investments, derivatives, debt and other contracts that will undergo reference rate-related modifications as a result of the Reference Rate

13

NOTES TO FINANCIAL STATEMENTS (continued)

Reform. Management has no concerns in adopting Topic 848 by FASB Sunset Date. Management will continue to work with other financial institutions and counterparties to modify contracts as required by applicable regulation and within the regulatory deadlines. As of November 30, 2022, management believes these accounting standards have no impact on the fund and does not have any concerns of adopting the regulations by FASB Sunset Date.

NOTE 2—Management Fee and Other Transactions with Affiliates:

(a) Pursuant to a management agreement with the Adviser, the management fee is computed at the annual rate of .08% of the value of the fund’s average daily net assets and is payable monthly.

The Adviser has undertaken to waive receipt of the management fee and/or reimburse operating expenses in order to facilitate a daily yield at or above a certain level which may change from time to time. This undertaking is voluntary and not contractual, and may be terminated at any time. The reduction in expenses, pursuant to the undertaking, amounted to $781,748 during the period ended November 30, 2022.

(b) The fund has an arrangement with BNY Mellon Transfer, Inc., (the “Transfer Agent”), a subsidiary of BNY Mellon and an affiliate of the Adviser, whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset Transfer Agent fees. For financial reporting purposes, the fund includes transfer agent net earnings credits, if any, as an expense offset in the Statement of Operations.

The fund has an arrangement with The Bank of New York Mellon (the “Custodian”), a subsidiary of BNY Mellon and an affiliate of the Adviser, whereby the fund will receive interest income or be charged overdraft fees when cash balances are maintained. For financial reporting purposes, the fund includes this interest income and overdraft fees, if any, as interest income in the Statement of Operations.

The fund compensates the Transfer Agent, under a transfer agency agreement, for providing transfer agency and cash management services for the fund. The majority of Transfer Agent fees are comprised of amounts paid on a per account basis, while cash management fees are related to fund subscriptions and redemptions. During the period ended November 30, 2022, the fund was charged $50 for transfer agency services. These fees are included in Shareholder servicing costs in the Statement of Operations. These fees were partially offset by earnings credits of $2.

14

The fund compensates the Custodian, under a custody agreement, for providing custodial services for the fund. These fees are determined based on net assets, geographic region and transaction activity. During the period ended November 30, 2022, the fund was charged $173,666 pursuant to the custody agreement.

During the period ended November 30, 2022, the fund was charged $17,027 for services performed by the fund’s Chief Compliance Officer and his staff. These fees are included in Chief Compliance Officer fees in the Statement of Operations.

The components of “Due to BNY Mellon Investment Adviser, Inc. and affiliates” in the Statement of Assets and Liabilities consist of: management fee of $685,704, Custodian fees of $89,877, Chief Compliance Officer fees of $2,721 and Transfer Agent fees of $16.

(c) Each Board Member also serves as a Board Member of other funds in the BNY Mellon Family of Funds complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

To the Shareholders and the Board of Trustees of Dreyfus Treasury and Agency Liquidity Money Market Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Dreyfus Treasury and Agency Liquidity Money Market Fund (the “Fund”) (the sole fund constituting Dreyfus Institutional Liquidity Funds), including the statement of investments, as of November 30, 2022, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the four years in the period then ended and the period from December 18, 2017 (commencement of operations) through November 30, 2018 and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund (the sole fund constituting Dreyfus Institutional Liquidity Funds) at November 30, 2022, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the four years in the period then ended and the period from December 18, 2017 (commencement of operations) through November 30, 2018, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of the Fund’s internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of November 30, 2022, by correspondence with the custodian, brokers and others; when replies were not received from brokers and others, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more investment companies in the BNY Mellon Family of Funds since at least 1957, but we are unable to determine the specific year.

THE BNY MELLON FAMILY OF FUNDS

BNY MELLON FUNDS TRUST

Principal Executive Officer and Senior Financial Officer

Code of Ethics

I.Covered Officers/Purpose of the Code

This code of ethics (the "Code"), adopted by the funds in the BNY Mellon Family of Funds and BNY Mellon Funds Trust (each, a "Fund"), applies to each Fund's Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller, or other persons performing similar functions, each of whom is listed on Exhibit A(the "Covered Officers"), for the purpose of promoting:

·honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

·full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the Securities and Exchange Commission (the "SEC") and in other public communications made by the Fund;

·compliance with applicable laws and governmental rules and regulations;

·the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

·accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

II.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview.  A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his service to, the Fund.  For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fund.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the "Investment Company Act"), and the Investment Advisers Act of 1940, as amended (the "Investment Advisers Act").  For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as "affiliated persons" of the Fund.  The compliance programs and procedures of the Fund and the Fund's investment adviser (the "Adviser") are designed to prevent, or identify and correct, violations of these provisions.  The Code does not, and is not intended to, repeat or replace these programs and procedures, and the circumstances they cover fall outside of the parameters of the Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fund and the Adviser of which the Covered Officers are also officers or employees.  As a result, the Code recognizes that the Covered Officers, in the ordinary course of their duties (whether formally for the Fund or for the Adviser, or for both), will be involved in establishing policies and implementing decisions that will have different effects on the Adviser and the Fund.  The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fund and the Adviser and is consistent with the performance by the Covered Officers of their duties as officers of the Fund and, if addressed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, will be deemed to have been handled ethically.  In addition, it is recognized by the Fund's Board that the Covered Officers also may be officers or employees of one or more other investment companies covered by this or other codes of ethics.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act.  Covered Officers should keep in mind that the Code cannot enumerate every possible scenario.  The overarching principle of the Code is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Fund.

Each Covered Officer must:

·not use his personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer would benefit personally to the detriment of the Fund;

·not cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fund; and

·not retaliate against any employee or Covered Officer for reports of potential violations that are made in good faith.

III.Disclosure and Compliance

·Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the Fund within his area of responsibility;

·each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's Board members and auditors, and to governmental regulators and self-regulatory organizations;

·each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Fund and the Adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

·it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

IV.Reporting and Accountability

Each Covered Officer must:

·upon adoption of the Code (or thereafter, as applicable, upon becoming a Covered Officer), affirm in writing to the Board that he has received, read, and understands the Code;

·annually thereafter affirm to the Board that he has complied with the requirements of the Code; and

·notify the Adviser's General Counsel (the "General Counsel") promptly if he knows of any violation of the Code.  Failure to do so is itself a violation of the Code.

The General Counsel is responsible for applying the Code to specific situations in which questions are presented under it and has the authority to interpret the Code in any particular situation.  However, waivers sought by any Covered Officer will be considered by the Fund's Board.

The Fund will follow these procedures in investigating and enforcing the Code:

·the General Counsel will take all appropriate action to investigate any potential violations reported to him;

·if, after such investigation, the General Counsel believes that no violation has occurred, the General Counsel is not required to take any further action;

·any matter that the General Counsel believes is a violation will be reported to the Board;

·if the Board concurs that a violation has occurred, it will consider appropriate action, which may include: review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the Adviser or its board; or dismissal of the Covered Officer;

·the Board will be responsible for granting waivers, as appropriate; and

·any waivers of or amendments to the Code, to the extent required, will be disclosed as provided by SEC rules.

V.Other Policies and Procedures

The Code shall be the sole code of ethics adopted by the Fund for purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder.  The Fund's, its principal underwriter's and the Adviser's codes of ethics under Rule 17j-1 under the Investment Company Act and the Adviser's additional policies and procedures, including its Code of Conduct, are separate requirements applying to the Covered Officers and others, and are not part of the Code.

VI.Amendments

Except as to Exhibit A, the Code may not be amended except in written form, which is specifically approved or ratified by a majority vote of the Fund's Board, including a majority of independent Board members.

VII.Confidentiality

All reports and records prepared or maintained pursuant to the Code will be considered confidential and shall be maintained and protected accordingly.  Except as otherwise required by law or the Code, such matters shall not be disclosed to anyone other than the appropriate Funds and their counsel, the appropriate Boards (or Committees) and their counsel and the Adviser.

VIII.Internal Use

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.
