Whalen says Basel III changes won’t pull banks back into mortgages

By AI, Created 4:29 PM UTC, May 18, 2026, /AGP/ – Veteran bank analyst Christopher Whalen says proposed Basel III tweaks are unlikely to reverse banks’ long retreat from residential lending. He argues the mortgage market has already shifted to nonbank lenders, and that regulation now needs to catch up with that reality.

Why it matters: - The U.S. mortgage market has shifted away from banks and toward nonbank lenders, changing where housing credit risk sits in the financial system. - Whalen warns that if policymakers misread that shift, future downturns could hit a thinner, more concentrated nonbank sector. - The debate matters for mortgage availability, market resilience, and how regulators assign capital against mortgage assets.

What happened: - Christopher Whalen, chairman of Whalen Global Advisors and publisher of The Institutional Risk Analyst, submitted comments to the Federal Reserve on proposed Basel III changes. - Whalen said the changes are unlikely to bring banks back into residential mortgages after a decade-long retreat. - Whalen said independent mortgage banks now control roughly two-thirds of mortgage origination and servicing. - The comments were released from Estero, Florida, on May 15, 2026.

The details: - Banks reduced holdings of residential loans, mortgage-backed securities, and servicing assets after the financial crisis. - Federal Reserve quantitative easing pushed down mortgage yields and filled the market with low-coupon, long-duration assets that banks found unattractive. - Government-backed housing finance also reduced returns. - Regulatory and legal risks raised costs and made mortgage activity more operationally complex. - Whalen said nonbank lenders saw profitability fall after QE ended and the pool of viable participants shrank. - Whalen said mortgage servicing is constrained by scale, technology, and operational risk, not just capital. - The proposal could give more favorable capital treatment to some off-balance-sheet structures than to similar on-balance-sheet loans. - The proposal leans heavily on loan-to-value ratios, even though rising home prices over the past decade may have lowered LTVs without eliminating credit risk.

Between the lines: - The core issue is not a single rule change. It is a long-running economics problem that pushed banks out of the business. - If capital rules treat mortgage risk as mainly a balance-sheet math problem, regulators may miss the operational and business-model forces that now shape lending. - A market dominated by a few large nonbanks may be efficient in calm periods but more fragile if credit conditions worsen.

What’s next: - Whalen is calling for a broader rewrite of mortgage regulation. - His recommended changes include aligning capital rules with actual collateral risk, revisiting the treatment of servicing assets, and narrowing the gap between bank regulation and modern housing finance. - Whalen Global Advisors said the full comment letter is available upon request.

The bottom line: - Basel III tweaks alone are unlikely to reverse the mortgage market’s migration from banks to nonbanks.
