Mortgage borrowing costs moved modestly lower during the week ending May 15, according to Freddie Mac’s Primary Mortgage Market Survey.
The average 30-year fixed mortgage rate declined to 6.01%, down from 6.05% the previous week. The 15-year fixed mortgage rate held steady at 5.60%, showing little change during the same period.
Adjustable-rate products also moved lower. The five-year ARM decreased to 5.57%, while the one-year ARM declined to 5.18%, both reflecting slight easing in short-term borrowing costs.
Rate Stability in a Transitional Market
The relatively small movement in rates during this period reflects a market that was adjusting rather than experiencing sharp swings.
Mortgage rates are influenced by a combination of factors, including bond market activity, inflation expectations, and broader economic conditions. During this stage of the housing cycle, rates often moved incrementally as financial markets processed new data.
Fixed vs Adjustable Mortgage Trends
One notable dynamic during this period was the difference between fixed and adjustable mortgage products.
While fixed rates showed minimal movement, adjustable-rate mortgages experienced slightly larger declines. This type of divergence can occur when short-term and long-term interest rate expectations begin to shift in different directions.
