US Q3 2026 PPI YoY Growth Drops to 4.7%; Cooling Inflation Strengthens Consensus for Fed Pause on Rate Hikes in September

US 30-Year Mortgage Rate Falls to 6.67%, Ending Five-Week Upward Streak

Core Overview: Latest data shows that in the third quarter of 2026 (for the week ending August 13), the US 30-year fixed mortgage rate slightly decreased to 6.67%, a minor pullback from 6.69% in the previous week. This is not only the first decline in the indicator since the summer, but also officially ends the previous continuous five-week upward streak. Compared to 6.58% in the same period last year, current funding costs remain at a relatively high level, but the recent marginal cooling has allowed the real estate market to gain some breathing room. Key Details: Observing from historical data, the current 6.67% has significantly pulled back compared to the swing high of 7.79% set at the end of October 2023. In addition, according to market surveys, the 15-year fixed mortgage rate also showed a decline, dropping from 6.01% in the previous week to 5.96%; meanwhile, data from the Mortgage Bankers Association (MBA) showed that the overall mortgage application volume increased by 3.6% in a single week, indicating that borrowers seeking refinancing and home purchases remain highly sensitive to minor interest rate changes. In-Depth Attribution: This slight decline in interest rates was primarily driven by the cooling of macroeconomic data. Recent weak employment reports and cooling inflation data have weakened market concerns about the Federal Reserve maintaining extremely high interest rates, directly driving down the US 10-year Treasury yield. Sam Khater, Chief Economist at Freddie Mac, pointed out that mortgage rates are currently maintaining relative stability, and the rebound in home purchase and refinancing application volumes reflects that as housing affordability marginally improves compared to the same period last year, buyers are beginning to show a willingness to enter the market on dips. Outlook and Risks: Looking ahead, in the short term (1-2 months), mortgage rates are expected to fluctuate within the 6.6% to 6.8% range. The main risk lies in the recurrence of inflation data or the policy attitudes of Federal Reserve officials, which may trigger market volatility. In the medium term (3-6 months), institutions generally provide forward guidance of a mild pullback; both Fannie Mae and MBA estimate that by the end of 2026, the 30-year mortgage rate is expected to gradually fall to the 6.4% to 6.5% range. Investors need to pay attention to Middle East geopolitics and energy prices; if a rebound occurs, it may become a key variable hindering further downward movement of funding costs.
