What Is 5/1 Adjustable-Rate Mortgage (ARM)?

6.2% sits in the lower portion of the recent historical range for 5/1 ARM. The reading is depressed relative to recent norms; the open question is whether this is a near-term cyclical low or the start of a more persistent shift.

5/1 ARM has moved lower from 6.2% to 6.2% since the prior weekly release — a modest move of -0.1%. Pair this with the related indicators below before drawing strong conclusions; isolated moves on a single release often look larger than they really are.

Interest-rate and yield indicators describe the cost of borrowing across the economy. The federal funds rate is set directly by the Federal Reserve; longer-term Treasury yields are set by the bond market and reflect investor expectations about future growth and inflation. See the FOMC for the current policy stance.

The 5/1 adjustable-rate mortgage (ARM) offers a fixed rate for the first 5 years, then adjusts annually based on a benchmark index plus a margin. ARMs typically start with a lower rate than 30-year fixed mortgages, making them attractive for buyers who plan to sell or refinance within 5-7 years.

At 6.17%, the 5/1 ARM offers a modest discount to the 30-year fixed rate of 6.64%. When this spread is narrow (under 0.5%), the risk-reward of choosing an ARM is less compelling — you take on rate adjustment risk for relatively little savings. A wider spread (1%+) makes ARMs more attractive. For real estate investors and corporate relocation programs, ARMs can reduce carrying costs on properties held for short periods.

Freddie Mac surveys lenders weekly. The 5/1 ARM rate reflects the initial fixed-rate period offered to well-qualified borrowers. After the 5-year fixed period, the rate adjusts annually based on the Secured Overnight Financing Rate (SOFR) index plus a lender margin, subject to periodic and lifetime caps.
