Independent mortgage banks have become a cornerstone of the American housing finance system. They originate a majority of new mortgages, service a growing portion of federally backed loans, and provide credit access in communities that might otherwise be underserved. Yet the regulatory framework governing large IMBs has not kept pace with their importance.
Today, the largest IMBs operate under a
Nonbank mortgage companies now occupy a central role in a market that is deeply connected to federal housing policy, the agency mortgage-backed securities market, and household financial stability. Recent public reports from federal agencies have repeatedly identified the same vulnerabilities: reliance on short-term funding, exposure to liquidity demands during stress and the difficulty of transferring servicing portfolios if a large servicer fails.
While some pin their hopes that
Congress could revise the regulatory framework so that larger IMBs are chartered and supervised primarily by one federal regulator, which would be granted preemption authority for these entities like the OCC for national banks and NCUA for federal credit unions.
One possibility is the Consumer Financial Protection Bureau, which already has broad supervisory authority over nonbank mortgage originators and servicers for compliance with federal consumer financial law. It has examination infrastructure, mortgage market expertise, and a national mandate. Congressman French Hill currently has a discussion draft that is looking to make changes to who should be supervised by the CFPB. Expanding that framework to make one entity the primary supervisor for larger IMBs would replace overlapping and sometimes inconsistent state-level supervisory regimes with a single, accountable federal structure. The OCC, which regulates the other large participants in mortgage, could be another possibility.
Some will argue that exclusive federal supervision could displace valuable state oversight. States have long played a central role in mortgage licensing and consumer protection. But the largest IMBs operate nationally, rely on federally backed markets, and can create risks that no individual state is positioned to manage alone. As with large banks with the OCC and federal credit unions with the NCUA, this would make the CFPB or other federal entity the primary supervisory examiner for larger IMBs. The objective is not to diminish states, but to match supervisory accountability to the scale of the risk.
For larger IMBs, there could also be one entity responsible for prudential supervision tailored to the mortgage banking business model. While currently many entities effectively serve this function (including FHFA, Ginnie Mae and states), there is an efficiency argument in having one agency taking the lead. These firms are not banks, though, and they should not be regulated as if they take deposits or rely on taxpayer-backed deposit insurance. But their size, market role, and obligations to borrowers and investors justify baseline safety-and-soundness standards that are developed in coordination with other stakeholders. A modern framework should recognize that consumer protection and prudential resilience are connected: a servicer that lacks liquidity, governance, or operational capacity cannot reliably assist distressed borrowers, process payments, manage escrow accounts, or execute loss mitigation.
A stronger supervisory framework should be paired with a liquidity facility of last resort for larger IMBs that meet prudential standards. Banks and credit unions who do mortgages can access the Federal Home Loan Bank system for liquidity, but IMBs cannot. Mortgage servicing can create extraordinary liquidity demands precisely when private credit becomes least available. Servicers may be required to advance principal, interest, taxes, insurance, or other payments even when borrowers are delinquent. They may also face margin calls, repurchase demands, or restricted access to warehouse funding during market stress. If a large servicer fails suddenly, borrowers, investors, and federal guarantors can all be harmed.
A liquidity facility would not be a bailout. It should be industry-funded, tightly conditioned, fully collateralized where possible, and available only to firms that are solvent, subject to enhanced supervision, and experiencing temporary market-wide liquidity stress. Access should carry a penalty rate, strong reporting obligations, restrictions on dividends and executive compensation while support is outstanding, and a clear repayment schedule. The facility should be designed to protect borrowers and market continuity, not shareholders. Firms that fail to meet prudential standards should not be eligible.
This combination — exclusive federal supervision, mortgage-specific prudential standards, and a liquidity backstop — would produce several benefits. It would give large IMBs a clear regulatory home and reduce duplicative supervision. It would strengthen confidence among investors, warehouse lenders, federal guarantors, and consumers. It would reduce the likelihood that stress at one large firm spills into broader market disruption. It would also create incentives for firms to maintain stronger balance sheets and governance because access to emergency liquidity would depend on compliance with rigorous standards.
Large independent mortgage banks are now core infrastructure for housing finance. They deserve a framework that recognizes their value, imposes standards appropriate to their role, and provides tools to manage stress without improvisation. The mortgage market has outgrown its supervisory architecture; Congress should build one that fits.
