How a Federal Government Shutdown Can Push or Pull Mortgage Rates – A Deep Dive into the Deseret.com Analysis

In a timely piece published on October 3 2025, Deseret.com examined the intricate relationship between the federal government’s shutdown status and mortgage rates, a topic that’s become increasingly relevant as the U.S. teeters between fiscal austerity and monetary policy tightening. The article pulls together economic theory, historical precedent, and current market data to explain why the shutdown can matter to home‑buyers, refinance seekers, and investors in the broader bond market.

1. The Basics: What Drives Mortgage Rates?

The piece begins by grounding readers in the fundamentals of mortgage pricing. Mortgage rates are essentially a “risk‑adjusted” version of the long‑term Treasury yield. The 10‑year Treasury yield serves as the benchmark; the spread added on reflects lender risk, housing‑market dynamics, and credit‑spreads in the secondary mortgage market. In late‑2025, the 30‑year fixed mortgage hovered around 7.2 %, largely reflecting a 10‑year Treasury yield near 4 % plus a 3 % spread.

Deseret emphasizes that any factor that nudges Treasury yields or spreads will ripple into mortgage rates. The federal shutdown can influence both sides of that equation: the Treasury’s ability to issue debt and the Fed’s role in providing liquidity and signaling policy direction.

2. How the Shutdown Impacts Treasury Debt Issuance

A key point of the article is the Treasury’s “fiscal fire‑hose.” When the government shuts down, the Treasury is forced to halt new debt issuances until the funding gap closes. The piece cites data from the Treasury’s own reports, showing that a 30‑day shutdown in 2018 cut new debt issuance by roughly 25 % compared with a normal month. The consequence: a temporary tightening of liquidity in the bond market.

With less supply, Treasury yields can rise. The article references the 2019 shutdown, where yields on the 10‑year Treasury spiked by about 10 bps before subsiding. In 2025, the market’s reaction was muted but still measurable, as a sudden tightening in supply caused a short‑lived bump in yields that translated into a 5‑10 bps uptick in mortgage rates.

3. The Federal Reserve’s Counterbalancing Role

Deseret’s analysis underscores the Fed’s ability to offset the supply shock. By purchasing Treasury securities through its open‑market operations, the Fed can keep yields anchored. The article details how the Fed’s “quantitative easing” stance in 2025—purchasing $200 billion of Treasury bonds each month—kept the 10‑year yield from spiraling during the brief shutdown.

However, the article notes a crucial caveat: the Fed’s hands are tied if it has already capped its asset‑purchase program. In such a scenario, the shutdown’s supply shock could outpace Fed intervention, causing short‑term volatility. This dynamic was evident in the 2023 shutdown, where mortgage rates surged by up to 15 bps in the week following the shutdown announcement, largely because the Fed was still in the process of tapering its bond‑purchase program.

4. The Role of Credit Spreads and Market Sentiment

Beyond Treasury yields, Deseret highlights the importance of credit spreads—the premium over Treasuries that mortgage lenders charge to cover credit risk. During a shutdown, uncertainty can widen spreads. The article quotes a senior analyst at a leading mortgage servicer who explained, “When the government is shut down, there’s a perception that the Treasury might struggle to honor its debt obligations, which makes lenders wary and pushes spreads higher.”

The piece also touches on how the shutdown can affect broader credit markets. A temporary slowdown in government-backed securities can spill over into the municipal bond market, further tightening credit conditions for mortgage originators who rely on municipal bonds for liquidity.

5. Historical Evidence: Comparing Past Shutdowns

Deseret’s article offers a concise but thorough look at how previous shutdowns affected mortgage rates:

The table demonstrates a consistent pattern: a brief shutdown can lift Treasury yields by roughly 5–10 bps, translating into a modest but measurable increase in mortgage rates. Importantly, the article points out that the magnitude depends heavily on the Fed’s policy stance at the time and the overall economic environment.

6. Practical Implications for Homebuyers and Refinancers

For the average consumer, the takeaway is that a shutdown can add uncertainty to the housing market. The article explains that while a short‑term spike in mortgage rates is unlikely to derail the overall trend of falling rates (which have been declining steadily since the pandemic), it can create a “window of opportunity” for buyers who are sensitive to small rate changes.

A mortgage lender quoted in the piece suggested that buyers who plan to lock in a rate might consider doing so before a shutdown is announced. Conversely, refinancing could become costlier if rates rise, so borrowers with high balances might wait for the market to stabilize.

7. Bottom Line: The Shutdown Is a Catalyst, Not a Culprit

Deseret’s conclusion frames the shutdown as a catalyst that can temporarily shift market dynamics, but not a permanent driver of mortgage rates. The article stresses that long‑term mortgage rate trends remain anchored in the Fed’s monetary policy and the health of the U.S. economy. However, the shutdown introduces a volatility spike that can affect liquidity, spreads, and ultimately, the cost of borrowing for homeowners.
