US Mortgage Rates Climb to 14-Month High Amid Inflation and Treasury Yields

Freddie Mac chief economist Sam Khater said purchase demand has remained relatively stable, indicating that buyers are adapting to the higher-rate environment rather than leaving the market.
The 10-year U.S. Treasury yield hovered around 4.74% and even spiked to 4.818% intraday, the highest level since November 2023, helping push mortgage rates higher.
Renewed U.S.-Iran tensions have pushed oil prices higher, reviving inflation concerns and contributing to the rise in long-term yields and mortgage rates.
Fed rate expectations remain volatile, with CME FedWatch showing near-equal odds for a 25-basis-point hike versus no change for the upcoming decision, around 50.4% to 49.6%.
Analysts highlight AI infrastructure investment and related corporate bond issuance as a new driver of higher long-term yields, alongside widening fiscal deficits.
US mortgage rates have climbed to their highest level in 14 months, with the 30-year fixed rate hitting 6.71%, according to Freddie Mac. The 15-year fixed rate stands at 6.04%, adding pressure on homebuyers already stretched by higher borrowing costs. The jump reflects a mix of inflation concerns, geopolitical tensions, and expectations about Federal Reserve policy.
The 10-year Treasury yield, which mortgage rates closely follow, hovered near 4.74% and spiked as high as 4.818% intraday — the highest since November 2023, according to market data. Rising oil prices tied to US-Iran tensions have reignited inflation worries. At the same time, heavy borrowing for AI infrastructure projects and widening fiscal deficits are keeping long-term borrowing costs elevated.
Purchase demand has remained relatively stable even as rates have surged, Freddie Mac chief economist Sam Khater said. Homebuyers are adjusting to the higher-rate environment rather than fleeing the market altogether. However, monthly mortgage payments on a typical home have grown substantially, and some buyers are choosing to delay purchases until conditions improve.
The higher rates do show signs of cooling the housing market. Pending home sales have fallen, and refinancing activity has declined sharply. The combination of elevated rates and lower turnover suggests a slower year ahead for real estate transactions.
Renewed tensions between the US and Iran have pushed oil prices higher, reviving concerns about inflation. Energy prices directly affect consumer spending power and business costs, keeping pressure on the 10-year Treasury yield. Since mortgage rates move in lockstep with the 10-year yield, rising oil prices translate quickly into higher borrowing costs for homebuyers.
The 10-year yield spiked to 4.818% intraday — a level not seen since November 2023 — before settling near 4.74%. According to CME FedWatch, Fed rate expectations remain volatile, with nearly equal odds of a 25-basis-point hike versus no change in the upcoming decision: 50.4% to 49.6%.
A new force keeping longer-term borrowing costs elevated is heavy capital investment in AI infrastructure. Tech companies are issuing large amounts of corporate debt to fund these projects, soaking up available credit and pushing bond yields higher. This competes with mortgage lending and makes it costlier for banks to fund home loans.
Widening federal fiscal deficits are compounding the problem. The Treasury must issue more debt to fund government spending, adding to the overall demand for borrowing. Together, geopolitical risk, energy prices, and tech-sector investment create a headwind that keeps mortgage rates above 6% even as some inflation readings ease.
The Federal Reserve's next policy move remains uncertain. CME FedWatch data shows the odds nearly split between a 25-basis-point rate hike and no change, leaving markets unsure about the Fed's inflation-fighting stance. Any signal from Fed officials about interest rates or growth could swing mortgage rates sharply in either direction.
Mortgage borrowers are watching the Fed closely because its policy decisions filter directly into longer-term yields and, in turn, mortgage rates. Even a small shift in rate expectations can add hundreds of dollars to annual borrowing costs. For now, rates appear likely to stay elevated until either inflation accelerates further or geopolitical tensions ease.
