Why reliable liquidity matters for housing finance

Housing affordability is a defining challenge of today’s economy, driven by supply constraints, construction costs, interest rates, and local policy decisions. These forces are complex and largely outside the control of any single institution. Discussions around subsidies, zoning reforms, and new programmatic solutions are important, but what often receives less attention is the role of reliable funding in ensuring that the housing finance system continues to function effectively, even when affordability challenges persist.

At its core, the housing finance system depends on lenders having consistent access to funding. When that access becomes uncertain or constrained, lending slows, credit availability tightens, and market volatility increases. In this way, liquidity does not determine affordability, but it plays a critical supporting role in ensuring that credit continues to flow and that financial institutions can serve their communities across all market conditions.

This is where the Federal Home Loan Bank (FHLBank) System–and the credit unions that participate in this member-owned cooperative–play a crucial role.

The link between liquidity and lending

The connection between stable funding and mortgage lending is well established. Research from the Urban Institute shows that access to FHLBank advances is associated with increased mortgage origination activity, particularly among smaller and mid-sized lenders. In other words, when institutions have reliable liquidity, they are better positioned to continue making loans, even in more challenging market environments.

A separate Urban Institute analysis reinforces this point, finding that ready access to liquidity improves institutional stability, reduces failure risk, and lowers overall systemic risk. These findings reinforce an important point: access to dependable liquidity supports not only the continued availability of credit, but it also improves the resilience of the financial system as a whole.

Credit unions: Local institutions, broad impact

Credit unions are uniquely positioned within the FHLBank System framework. Deeply embedded in the communities they serve, credit unions bring a relationship-based approach to lending that prioritizes long-term member outcomes over short-term market cycles.

Through their membership in the FHLBank System, credit unions are able to:

• Convert illiquid mortgage assets into funding that supports new lending
• Maintain lending capacity during periods of market stress
• Continue serving borrowers who might otherwise face reduced access to credit

Importantly, this is not just about balance sheets. It is about outcomes. Through the FHLBanks’ member-driven cooperative structure, credit unions translate liquidity into locally delivered credit, helping families finance homes, refinance mortgages, and navigate changing economic conditions in the communities they serve.

Recent research by the Filene Research Institute supports this dynamic, finding that credit unions that are FHLBank members tend to have higher assets, stronger loan-share ratios, greater borrowing capacity, and increased access to capital markets, as reflected in higher levels of first-lien mortgage sales. In today’s environment, these findings underscore how access to FHLBank liquidity strengthens lending capacity and member service.

Why this matters now

Today’s housing market presents real challenges. Elevated interest rates have increased borrowing costs, while supply constraints continue to put upward pressure on home prices. At the same time, smaller and community-based lenders, including many credit unions, face increased competition for funding.

In this context, access to reliable liquidity is not just helpful, it is foundational.

The FHLBank System provides a consistent source of secured funding that allows credit unions to plan, lend, and serve with confidence, even when broader market conditions are uncertain. This stability helps ensure that mortgage credit remains available and that disruptions in funding do not further strain an already challenging housing market.

A system that works together

Housing finance in the United States is a collaborative effort. It depends on the participation of borrowers, lenders, investors, and liquidity providers working together to support access to credit and promote financial stability.

The FHLBanks play a foundational role in this ecosystem. Through the community-centric focus of their members – including their credit union members – they support a model that helps deliver homeownership opportunities in a way that is both resilient and locally responsive.

At a time when affordability challenges are front and center, it is worth recognizing the systems and partnerships that help maintain access to credit and financial stability in the housing finance market. Ensuring that these foundations remain strong will be essential as we navigate the challenges ahead.
