On Friday, August 14th, the housing finance market felt renewed pressure from rising long-term interest rates. The latest average interest rate for a 30-year fixed mortgage in the US was 6.67%, a slight decrease from 6.69% the previous week, but still higher than 6.58% in the same period last year, and significantly higher than the levels around February this year. Meanwhile, the yield on the 10-year US Treasury note fell to approximately 4.65% on August 13th, after previously rising to around 4.72%. This short-term decline has not changed the core issue: energy prices, inflation risk premiums, and monetary policy expectations continue to collectively raise the pricing center of housing finance. The most important issue at present is not whether the Federal Reserve will immediately adjust policy rates, but how the long-term market will reassess future inflation. On July 29th, the Federal Reserve maintained the target range for the federal funds rate at 3.50% to 3.75%, but the vote was 9 to 3, with three members favoring a 25 basis point rate hike, reflecting a widening divergence of opinion among policymakers regarding inflation risks. Mortgage rates, especially 30-year fixed-rate products, do not directly follow the overnight policy rate. Instead, they are more influenced by the 10-year Treasury yield, term premium, and mortgage-backed securities spreads. Therefore, even if the Federal Reserve maintains short-term interest rates unchanged, as long as the market increases its demand for long-term inflation compensation, the actual financing costs faced by residents may remain high. This structure means that the current US housing market is no longer facing a simple issue of "central bank interest rates," but rather a repricing of the entire yield curve. Changes in energy prices first affect inflation expectations, then enter long-term Treasury yields, and finally transmit to mortgage products. For real estate, this transmission is often more direct than policy interest rates themselves. Recent conflicts in the Middle East have continued to disrupt the energy market. On August 13, Brent crude closed at $87.07 and US crude closed at $81.25. Although both fell on the day, the previous continuous rise had reinforced market concerns about the transmission of energy costs to residents and businesses. This impact is not limited to the US. On July 23, the European Central Bank maintained its deposit facility rate at 2.25%, its main refinancing rate at 2.40%, and its marginal lending facility rate at 2.65%, while clearly stating that energy prices are still significantly higher than pre-conflict levels, and the full inflationary impact has not yet been fully reflected. The ECB's June forecast showed that the Eurozone's overall inflation averaged 3.0% in 2026, potentially reaching 3.4% in the third and fourth quarters, with energy inflation expected to reach 12.5% in the third quarter. This means that market pricing has shifted its focus from a one-off energy price increase to whether it will continue to spread to goods, services, and residents' inflation expectations. For the bond market, once investors believe the rate of inflation decline is slowing, long-term yields need to incorporate higher inflation compensation and term premiums. The housing market thus becomes one of the most directly pressured links in this macroeconomic chain. When the US 30-year fixed mortgage rate is above 6%, a significant gap exists between existing low-interest loans and new financing costs. Many homeowners who previously locked in low interest rates often face significantly higher financing costs when repurchasing, reducing their willingness to upgrade and creating a typical "lock-in effect" in the existing housing stock. This mechanism simultaneously compresses supply and transactions. Sellers are unwilling to release low-cost mortgages, while buyers are limited by rising monthly payments. The result may not be an immediate and significant adjustment in housing prices, but rather changes in transaction volume, listing cycles, and housing liquidity. The pressure in the UK is more characteristic of refinancing. The Bank of England maintained the bank rate at 3.75% in July, but the UK market heavily utilizes two- or five-year fixed mortgages. Therefore, after the fixed term expires, residents are more directly exposed to a new financing environment. As of the end of July, the average interest rate for a five-year fixed mortgage in the UK was approximately 5.64%, with subsequent data showing it remained in the range of approximately 5.66% to 5.67%. Meanwhile, UK house prices rose by only about 0.1% year-on-year in July, indicating that financing costs have significantly limited demand elasticity. In Germany, the representative 10-year fixed mortgage rate rose from approximately 3.3% in early July to approximately 3.7% in early August, while the average 10-year mortgage rate in France reached 3.15% in July. During the same period, the average rates for 15-year, 20-year, and 25-year mortgages in France were approximately 3.20%, 3.36%, and 3.48%, respectively. This data illustrates that even with significant differences in housing financing structures across different economies, the underlying pricing logic is converging. Energy risks increase inflation uncertainty, which in turn raises medium- and long-term risk-free interest rates and swap rates, leading banks to factor in higher funding costs and risk premiums into fixed mortgages.
