Mortgage Applications Jump 7.9% — Purchases Lead at 10%

+7.9%. The Mortgage Bankers Association's Weekly Applications Survey, released April 22 for the week ending April 17, posted its largest weekly gain since late February — as the MBA's 30-year conforming contract rate slipped 7 basis points to 6.53%. The 15-year fixed fell harder, down 12 bps to 5.92%. The survey's composite index captures both purchase and refinance activity, and both moved — unevenly.

The decomposition:

Purchase demand leading refi on a rate drop is not the typical pattern. In a lock-in-dominated market, rate relief usually wakes refinancers first — they have the equity and the friction is lower. Purchases leading by a 4-point margin suggests buyers who were already pre-qualified and watching the 6.50% threshold converted once the contract rate slipped through it. The 51.9% YoY refi print is the lock-in ceiling starting to leak: rates a year ago averaged roughly 7%, so every borrower who locked between March 2025 and July 2025 is now screening their statements for a break-even.

The 30-year PMMS from Freddie Mac — a separate weekly survey that tends to run a few basis points below MBA's — hit a 4-week low over the same window. Two independent rate tapes confirming the same direction is the cleaner read than either alone.

Also moving

• 11 states now above pre-pandemic 2019 inventory, per ResiClub Analytics. National active listings remain 13.6% below the March 2019 baseline — the gap is concentrated in the Northeast and California.
• Census housing starts for March were delayed from April 17 to April 29 (Census NRC calendar). The next BPS permits print and the starts print will now land in the same release.

Editor's Read

A 7-bps rate move buying 10% more purchase applications is the demand-rate sensitivity curve plotted in a single data point. I'm watching next week's print to see whether the purchase index holds the gain or gives it back. The FOMC decision April 28-29 is the variable.
