Treasury Market Practices Group Seeks Comment on Consultative Summary Note Titled "Theoretical Implications for Agency MBS Market Liquidity and Functioning of any Potential GSE Ownership Structure Changes"

The Treasury Market Practices Group (TMPG) today released a consultative summary note Theoretical Implications for Agency MBS Market Liquidity and Functioning of any Potential GSE Ownership Structure Changes, as part of the ongoing work of the TMPG’s Agency Mortgage-Backed Securities (MBS) Working Group. Given renewed public focus on potential changes in the ownership structure of the Government Sponsored Enterprises (GSEs) and the criticality of the agency MBS market, the TMPG explored hypothetical implications for agency MBS market liquidity and functioning in light of any such change. The TMPG seeks comment on this consultative summary note by April 30, 2026.
