A golden window of opportunity for Fannie Mae and Freddie Mac
The Fed's recent bank capital rule proposals could accelerate the end of America's longest conservatorship
On March 19, 2026, the Federal Reserve, FDIC, and OCC took a major step toward reshaping U.S. banking regulation. In a coordinated set of proposals, the agencies outlined revisions to the U.S. Standardized Approach and an expanded risk-based approach for larger banks. The changes are explicitly designed to be more risk-sensitive and less punitive than the 2023 Basel III endgame proposal, particularly for traditional lending activities like residential mortgages and mortgage servicing. Overall, large banks could see capital requirements fall by approximately 4.8 percent, with midsize institutions benefiting from a 5.2 percent reduction and smaller banks up to 7.8 percent.
The driving rationale, as articulated by Fed officials and echoed in coverage including The Wall Street Journal, is to reverse the migration of mortgage origination, holding, and servicing out of the regulated banking system into nonbanks and GSEs. By making on-balance-sheet mortgage activity more capital-efficient, regulators hope to broaden participation, improve liquidity, and support housing access without compromising safety.
This article takes a deep dive into these proposals, with a sharp focus on the mortgage-specific provisions. It then compares them to the far more conservative Enterprise Regulatory Capital Framework that governs Fannie Mae and Freddie Mac. Finally, it explores the central hypothetical:
What if FHFA rewrote the ERCF to mirror the new bank rules exactly?
How much capital would each GSE actually need?
How does that compare to their current GAAP net worth?
And, assuming the senior preferred stock held by Treasury is deemed repaid through administrative or legislative action, how quickly could the Enterprises exit the seventeen-year-old conservatorship?
All figures are drawn from the GSEs’ official disclosures, the agencies’ March 19 proposals, and contemporaneous analyses. While no such alignment has been proposed or announced, the potential for it is a golden opportunity for FHFA (Fannie and Freddie’s regulator) to finally get the ball moving on returning these two financial giants to public markets.
