August CPI at 3.4% Lifts Mortgage Rates, Raises Fed Hike Odds

Mortgage rates rose for the second consecutive day as of Saturday, September 12, 2026, according to data from the Zillow lender marketplace, adding pressure on homebuyers and refinancers at a time when broader inflation remains elevated and consumer confidence has slipped. The national average for a 30-year fixed mortgage climbed eight basis points to 6.91 percent, while the 15-year fixed rate increased 14 basis points to 6.37 percent. The 5/1 adjustable-rate mortgage edged up one basis point to 6.85 percent. Refinance rates followed a similar pattern, with the 30-year fixed option holding at 6.91 percent and the 15-year fixed at 6.29 percent.

These increases come as the latest Consumer Price Index report showed prices rising at a 3.4 percent annual pace in August, a figure that has kept the Federal Reserve on track to consider further rate hikes. A separate University of Michigan survey released the same day recorded a sharp drop in consumer sentiment for the month. The combination of climbing borrowing costs and persistent price pressures has complicated President Trump's final push to maintain Republican control of Congress in the November midterms.

At the party's midterm convention in Dallas earlier in the week, Trump described Republican economic stewardship as delivering tremendous success and insisted that prices had fallen way, way down. Yet fuel costs have climbed, mortgage expenses have increased, and inflation has stayed above the central bank's target throughout much of his term. Analysts have linked the price trends to an agenda that featured extended trade tensions with major partners and a drawn-out conflict with Iran, both of which have contributed to higher energy and goods costs.

The mortgage-rate movement directly affects millions of households. Higher rates raise monthly payments on new home loans and make refinancing less attractive for existing borrowers seeking relief. The Zillow figures represent averages rounded to the nearest hundredth and reflect offers available through its marketplace; actual rates for individual borrowers can vary based on credit, down payment and loan size. For context, the 30-year VA loan averaged 6.26 percent while the 15-year VA option stood at 5.84 percent.

Economic data released Friday has heightened concerns among voters already frustrated by the cost of living. The inflation reading increased the likelihood that borrowing costs will remain elevated into the fall, potentially slowing any housing-market recovery. Consumer sentiment surveys have shown growing pessimism about personal finances and the broader outlook, a trend that historically correlates with weaker support for the party in power during midterm cycles.

Trump's messaging has centered on claims of restored prosperity, yet the gap between those assertions and the lived experience of higher monthly housing costs and elevated prices has become a central vulnerability. With two months until Election Day, the administration faces the challenge of convincing voters that current conditions represent improvement rather than continuation of the pressures that have defined recent years. The mortgage and inflation figures released over the past week provide concrete data points that opponents are likely to highlight in the closing stretch of the campaign.
