Mortgage rates climbed Wednesday as geopolitical tensions between the U.S. and Iran escalated. The typical 30-year fixed mortgage hit 6.53 percent, up from 6.48 percent on Tuesday. The 15-year fixed rate rose to 5.99 percent from 5.95 percent the previous day.

Bond markets drove the increases. When geopolitical risk rises, investors typically shift money into Treasury bonds, treating them as safe havens. This buying pressure pushes Treasury yields down temporarily. However, mortgage rates follow a different path. Lenders price mortgages based on mortgage-backed securities, not directly on Treasury bonds. The uncertainty itself, combined with expectations of higher future inflation from potential conflicts, pushed rates upward.

This matters for anyone shopping for a home or refinancing. A half-percentage-point jump sounds small but costs real money. On a $400,000 mortgage, the difference between 6.48 percent and 6.53 percent adds roughly $13 monthly to your payment. Over 30 years, that totals more than $4,600.

Prospective buyers facing this rate environment should accelerate timelines if they were planning to move within the next few months. Rates remain historically elevated compared to 2021 and early 2022, when averages hovered around 3 percent. However, they've stabilized below the 7 percent peaks seen last year.

Current borrowers with older mortgages locked in below 5 percent should hold tight. Refinancing at these rates erases any advantage gained from lower previous rates.

Adjustable-rate mortgages offer temporarily lower initial rates, but borrowers face future payment increases when rates reset. These work only for sellers planning to move within three to five years.
