Surging Mortgage Rates Suppress Demand; US Q2 MBA Purchase Index Edges Down to 169.7

2026-05-28

Core Overview: Based on the latest data provided by DataTrack, for the week ending May 22, 2026 (Q2 2026), the US MBA Purchase Index recorded 169.7, edging down slightly from 170.4 in the previous week. This data not only interrupted the brief recovery trend seen since April but also reflects that in an environment of rising borrowing costs, the willingness of potential homebuyers to enter the market has turned conservative, and the buying momentum in the housing market is facing a test.

Key Details: Observing the relevant key details, the benchmark 30-year fixed mortgage rate further increased from 6.56% to 6.65% during the week, hitting the highest level in nearly nine months since August 2025. The high-interest-rate environment has caused a comprehensive impact on the mortgage market. Not only did purchase mortgage applications shrink slightly, but the overall MBA Mortgage Market Index also plummeted 8.5% to 259.4. Among them, the highly rate-sensitive Refinance Index plunged 18% to 753.7, indicating that borrowers are deterred by the current high interest costs.

Deep Attribution: Regarding the changes in this wave of data, Joel Kan, Vice President and Deputy Chief Economist at the MBA, pointed out: "Over the past five weeks, the 30-year fixed mortgage rate has cumulatively increased by 30 basis points. With rates reaching 6.65%, many borrowers have naturally stepped out of the refinance market." Financial market analysis also indicates that the stickiness of recent inflation data and the rise in long-term US Treasury yields are the fundamental reasons driving up mortgage rates. This not only weakens the willingness of existing homeowners to refinance but also substantially compresses the purchasing power and homebuying enthusiasm of first-time buyers.

Outlook and Risks: Looking ahead, in the short term (1-2 months), due to persistently high mortgage rates and the relatively slow release of housing inventory, buyers' affordability will remain under pressure. It is expected that the MBA Purchase Index will fluctuate weakly in the 160 to 170 range. In the medium term (3-6 months), the biggest market variable remains the Federal Reserve's (Fed) monetary policy path. If inflation fails to cool as expected, causing mortgage rates to hover above 6.5% for a prolonged period, it will pose a significant downside risk to the recovery of US existing home sales in the second half of this year. Investors need to pay close attention to the guidance of relevant macroeconomic data.
