Securities Lending


Last updated: 3/16/2023
Securities lending is a recognized and established activity in financial markets that helps provide liquidity to markets and extra returns to investors who lend securities. The securities lending market involves lending of securities by institutional investors, such as insurance companies, to mostly banks and broker-dealers. It requires that the borrower post collateral in the form of cash or security. Insurance companies generally engage in securities lending to enhance returns on their investment portfolios, loaning out securities that are not actively traded.

Overview: Data on the securities lending market are estimated based on surveys. According to the Financial Stability Oversight Council’s (FSOC) 2021 annual report, the estimated value of securities on loan globally was $3.1 trillion at the end of September 2021. This is up from $2.5 trillion at the end of September 2020. The Estimated U.S. share of the global activity grew to 58% at the end of September 2021 from 57% the previous year. To improve data collection on securities lending, in 2014 the Office of Financial Research (OFR), the Federal Reserve System, and the Securities and Exchange Commission (SEC) began a pilot data collection project focused on activity in this area. A summary report on the findings was published in 2016.

In its 2012 consultation paper, Strengthening the Oversight and Regulation of Shadow Banking, the Financial Stability Board (FSB) examined the complex and rapidly evolving securities lending markets. While the FSB acknowledges the benefits to the financial markets, aspects of securities lending are an issue of concern, particularly their procyclical nature, their lack of transparency, and the ways they may help to transmit negative market events in one part of the globe to another.

Securities lending is intended to be a low-risk investment strategy, providing the lender a modest income through fees charged to borrowers. Additional income may be generated by investing the cash collateral posted by the transactions' borrowers. The securities lending agreement spells out the term of the loan, the fee that the lender receives and the amount and type of collateral to be posted, among other items. The collateral is generally between 102% and 105% of the fair value of the securities loaned. Upon investing the posted collateral, insurance companies must consider credit and liquidity risks, as well as the asset/liability management risks of the potential investments. Insurance companies must also follow the appropriate statutory accounting rules related to securities lending transactions, which are included in the NAIC Accounting Practices and Procedures Manual. Insurance companies' individual investment policies should address the types and duration of investments that can be made with the cash collateral.

In general, securities lending transactions have a term of less than one year; however, terms can vary across different agreements. And, in most cases, the borrower may return the borrowed security and request its cash collateral back on relatively short notice, without penalty.

According to guidance in the Statement of Statutory Accounting Principles (SSAP) No. 103, "Collateral which may be sold or repledged by the transferor or its agent is reflected on balance sheet, along with the obligation to return the asset. Collateral received which may not be sold or repledged by the transferor or its agent [i.e. must be held and returned] is off-balance sheet." Note that for both on- and off-balance sheet reinvested collateral, summary information is required to allow for identifying potential liquidity constraints related to any potential duration mismatches.


Since 2010, securities lending transactions are subject to more defined valuation rules and disclosure requirements. A new Schedule DL was implemented in 2010 which includes a detailed listing of the invested collateral, including separate categories for bonds, preferred stock and common stock. These reporting changes provide more transparency whether insurers are overcollateralized or undercollateralized.
