30-year fixed purchase rates fall 5 basis points below refinance rates as of August 17, 2026, marking a rare inversion.
National average purchase mortgage rates dropped below refinance rates for the first time in months on August 17, 2026. The 30-year fixed purchase rate stands at 6.54%, 5 basis points lower than the refinance rate of 6.59%. The 15-year fixed purchase rate is 5.86%, 2 basis points below its refinance counterpart, while the 5/1 ARM purchase rate is 6.24%, 20 basis points lower than the refi rate.
Refinance rates have typically held below purchase rates, though the gap has narrowed in recent weeks. Last week, the 30-year refinance rate averaged 6.62%, compared to today’s 6.59%. The inversion is most pronounced in adjustable-rate mortgages, where the 5/1 ARM purchase rate undercuts refinance rates by the largest margin.
The shift reflects lenders adjusting pricing amid cooling demand for refinancing. Borrowers may see lower upfront costs but higher fees, as lenders seek to offset reduced refinance volume.
