The primary objective of the securities portfolio is to provide a readily available source of liquidity. The portfolio primarily includes high quality, highly liquid investments reflecting our ongoing commitment to maintain strong contingent liquidity levels and pledging capacity.

As of March 31, 2024, U.S. Treasuries and mortgage-backed securities issued by GNMA and GSEs represented 97% of the fair value of our debt securities portfolio, with approximately $31.5 billion of unencumbered high-quality liquid securities serving as potential collateral for borrowings from the FHLB, FRB discount window, and the Fixed Income Clearing Corporation bilateral repurchase agreement market.

For further discussion of the use of our securities as liquidity collateral see the “Liquidity Risk Management and Governance” section in this document. For further discussion of liquidity requirements, see “Regulation and Supervision — Liquidity Requirements” in our 2023 Form 10-K.

We manage our securities portfolio duration and convexity risk through asset selection and securities structure, and maintain duration levels within our risk appetite in the context of the broader interest rate risk framework and limits. As of March 31, 2024, the portfolio’s average effective duration, including recent hedging actions to reduce duration, was 3.8 years compared with 3.9 years as of December 31, 2023.
