U.S. mortgage rates return to near 7%, inflation concerns affect both Bitcoin and Fed decisions.
As U.S. mortgage rates return to 7%, inflation anxiety that plagues home buyers is also reshaping the market outlook for Bitcoin, Treasury bonds and next week's Fed meeting. According to Reuters, the average interest rate on a 30-year fixed-rate mortgage rose to 6.85% in the week ending September 4, the highest level since June 2025. Rising U.S. bond yields are the main driver, with 10-year U.S. bond yields climbing towards 4.8%. Investors are responding to strong economic data, high oil prices and persistent inflation concerns.
Another data showed that for the week ended September 3, the average mortgage interest rate surveyed by Freddie Mac was 6.71%, up slightly from 6.66% the previous week. Although we have focused on the recent upward trend in mortgage interest rates, the next key catalyst is now particularly clear: inflation.
CPI may act before the Federal Reserve and push mortgage interest rates upward.
The Federal Reserve does not directly set mortgage interest rates. Mortgage pricing mainly refers to long-term U.S. bond yields and mortgage-backed securities (MBS), and price fluctuations of these assets often reflect expectations for inflation and monetary policy. This means that home loan rates may rise first before the Federal Reserve formally adjusts its benchmark interest rate.
The August consumer price index (CPI) will be released on September 11, just a few days away from the Federal Reserve's September 15 - 16 interest-rate meeting. Markets are divided on whether policymakers will raise interest rates or maintain the status quo. A Reuters poll showed that most economists still expect no change in September, but a growing number of people believe there will be at least one additional rate hike this year.
Oil price trends make this decision more complicated. Brent crude oil broke through the US$100 per barrel mark on Wednesday, boosting the yield on 10-year U.S. bonds to about 4.84%, a new high since the end of 2023. If the CPI report data is hot, it may further push up yields and mortgage interest rates; conversely, if the data is moderate, it may bring breathing room. In addition, explanations for the difference between CPI and PCE (Personal Consumption Expenditure Price Index) also reveal why the market reacted so strongly to CPI, even though the Federal Reserve's official goal is to control PCE inflation.
Bitcoin also looks at bond markets
The current market environment is also affecting the cryptocurrency space. Bitcoin hovered in the $78,700 to $79,000 range on Wednesday and failed to recover the $79,500 mark, as traders awaited inflation data released on Friday. As a result, Bitcoin's recent rebound has essentially become another manifestation of interest rate trading.
Rising yields not only increase the cost of mortgage loans, but also increase the opportunity cost of holding non-interest-bearing assets such as Bitcoin and gold. Previously, when strong employment data pushed up interest rate hikes expectations, the tension Bitcoin faced in testing the $80,000 mark was highlighted.
