US Q3 ISM Services Business Activity Rebounds Strongly to 59.1 Amid World Cup Effect and Inflation Concerns

US MBA Purchase Index Drops to 154.0 as Rising Mortgage Rates Batter Housing Market Sentiment

Core Overview: According to the latest data provided by DataTrack, the US MBA Purchase Index for Q3 2026 (for the week ending July 31) reported at 154.0, representing a significant pullback compared to the previous week's 159.8. This data indicates that in an environment of climbing borrowing costs, the willingness of potential buyers to purchase homes is cooling rapidly, and housing market demand is facing heavy downward pressure. Key Details: Observing the related detailed data, high interest rates have become the core culprit suppressing buying sentiment. Supplementary market data shows that the average contract interest rate for a 30-year fixed-rate mortgage climbed 5 basis points that week to 6.81%, marking a new high in over a year. Impacted by this, total mortgage application volume fell by 2.9% for the week, with home purchase loan applications dropping 4% week-over-week and 3% year-over-year, reflecting a comprehensive contraction in real homebuying momentum. In-depth Attribution: Regarding this weak data, analytical institutions point out that geopolitical risks and inflation concerns are the main driving factors. Escalating conflicts in the Middle East have pushed up global energy prices, subsequently driving up long-term US Treasury yields and causing mortgage rates to rise in tandem. The MBA's Chief Economist noted that long-term rates have continued to climb since the July FOMC meeting, and persistently high borrowing costs have substantially weakened overall housing market demand, causing buyers who were previously on the sidelines to pull back further. Outlook and Risks: Looking ahead to the market's future, in the short term (1-2 months), as long as Middle East geopolitical and oil price volatility risks remain unresolved, US Treasury yields will continue to fluctuate at high levels. Consequently, housing market demand is bound to remain suppressed by high mortgage rates, leaving limited room for a rebound in the purchase loan index. In the medium term (3-6 months), the direction of the Federal Reserve's monetary policy will be a key catalyst. If inflation data slows down and prompts the Fed to initiate a rate-cut cycle, driving a real decline in mortgage rates, deferred homebuying demand is expected to be released again, bringing an opportunity for market recovery.
