Basel III Revision Debate: Housing and Banking Groups Call for Capital Relief
A coalition of leading housing and banking organizations is asking federal regulators to revise mortgage capital rules, arguing that current requirements are limiting bank participation in home lending.
In a joint letter sent to the Federal Reserve, the Office of the Comptroller of the Currency, and the Federal Deposit Insurance Corporation, eight major industry associations called for changes to existing capital standards tied to residential mortgages.
The groups say recalibrating these rules would strengthen housing affordability and encourage banks to return to mortgage origination, servicing, and securitization.
Why Banks Want Capital Rule Changes
The letter comes shortly after Federal Reserve Vice Chair for Supervision Michelle Bowman said the central bank is preparing to revisit certain bank capital standards. According to her remarks, the Fed is considering adjustments that could increase incentives for banks to originate and service mortgages.
Industry leaders argue that over the past decade, capital requirements have made mortgage lending less attractive for banks. As a result, more activity has shifted to non-bank lenders.
Data cited in the letter shows that bank servicing share dropped from 88% in 2013 to 39% in 2024, following the rollout of earlier Basel III capital standards.
Focus on the Basel III Endgame Rule
At the center of the debate is the proposed Basel III Endgame rule, a regulatory framework designed to strengthen bank capital levels after the financial crisis.
The coalition says current mortgage capital rules include:
- High risk weights for single-family mortgages held on bank balance sheets
- Strict capital treatment of mortgage servicing rights (MSRs)
- Elevated risk weights for warehouse lending
- Limited recognition of private mortgage insurance
- Capital penalties for securitization and credit risk transfer
According to the groups, these measures no longer reflect today’s mortgage market conditions, which they describe as stronger and more regulated than before the 2008 crisis.
Specific Changes Requested
The coalition, which includes the Mortgage Bankers Association, the American Bankers Association, the Housing Policy Council, and the U.S. Mortgage Insurers, outlined several recommendations:
- Adopt more detailed risk weights based on loan-to-value ratios.
- Provide proper capital credit for private mortgage insurance.
- Remove or significantly raise the 25% cap on mortgage servicing rights included in regulatory capital.
- Reduce the 250% risk weight on MSRs to 100%.
- Lower risk weights on warehouse lines of credit from 100% to 50%.
Warehouse lines are short-term loans that fund roughly two-thirds of all single-family mortgage originations before the loans are sold into the secondary market. The groups argue that these loans are highly collateralized and pose limited risk.
Impact on Housing Affordability
Industry leaders say easing mortgage capital rules could improve access to credit and increase competition in the lending market.
When banks scale back mortgage activity, non-bank lenders often fill the gap. While non-banks play a large role in today’s housing finance system, banks typically have lower funding costs and broader balance sheets.
Supporters of reform argue that stronger bank participation could help stabilize mortgage markets during periods of economic stress.
They also emphasize that post-financial-crisis reforms — including tighter underwriting standards and enhanced oversight — have reduced systemic risk, making some of the original capital measures less necessary.
What Happens Next?
Regulators are reviewing the Basel III Endgame proposal and have indicated a willingness to consider revisions. However, any changes would require formal rulemaking and public comment.
If adopted, adjustments to mortgage capital rules could reshape how banks allocate capital toward home loans and mortgage servicing.
For homebuyers, the impact would not be immediate. But over time, greater bank involvement could increase loan availability and potentially ease some pressure in a market still facing affordability challenges.
The debate reflects a broader question facing regulators: how to balance financial system safety with access to credit in a housing market that remains tight and competitive. For direct financing consultations or mortgage options for you visit 👉 Nadlan Capital Group.
