The average 30-year fixed mortgage rate rose to 6.42% on Sunday, June 21, 2026, climbing 7 basis points from the previous week, according to Zillow data reported by Yahoo Finance.
The increase reflects broader market dynamics in mortgage rates today, which are tied to long-term Treasury yields rather than the Federal Reserve’s benchmark rate. Last week, the Federal Open Market Committee voted to hold its target federal funds rate unchanged at 3.5% to 3.75%, according to CNBC, but this decision didn’t immediately ease mortgage rates.
Mortgage rates respond to multiple economic signals beyond the Fed’s direct policy moves. Inflation expectations, global market conditions, and bond market sentiment all influence the 10-year Treasury yield, which serves as the primary benchmark for 30-year mortgage rates, according to sources including X2 Mortgage and the Federal Reserve Bank of St. Louis. When inflation concerns rise or economic growth appears stronger, Treasury yields climb, pulling mortgage rates higher with them.
The 15-year fixed rate also moved higher, rising 1 basis point to 5.79%, while adjustable-rate mortgages saw more pronounced increases: the 5/1 ARM jumped 40 basis points to 6.70%, according to the Zillow data. For borrowers evaluating refinance options, the 30-year refinance rate stood at 6.30%, typically running lower than purchase rates.
Mortgage rates have remained elevated throughout 2026. The Mortgage Bankers Association forecasts that 30-year rates will average 6.5% for the year, while Fannie Mae projects rates will close 2026 at approximately 5.9%, suggesting some potential moderation later in the year. CBS News reported in early June that mortgage interest rates are unlikely to drop materially in the near term, as the Fed is positioned to maintain its current stance.
