On October 1, 2026, the yield on 10-year US Treasury bonds reached 5.33 percent – the highest level since May 2002. At the same time, the 30-year yield climbed to 5.67 percent and the 2-year yield to 4.92 percent. The development marks a historic turning point in the bond market, even though PCE inflation data from September 30, 2026 came in below expectations.
PCE Inflation Weaker Than Expected – Fed's Course in Limbo
The PCE price index – the Federal Reserve's preferred inflation measure – rose 3.4 percent year-over-year in August 2026. Core PCE, which excludes volatile energy and food prices, increased 0.2 percent month-over-month, falling short of the market expectation of 0.3 percent. The Federal Reserve targets a 2 percent inflation goal as measured by the PCE price index.
The downward miss was due to stronger revisions from the Bureau of Economic Analysis than analysts had expected. MUFG/BTMU explained that revisions of 10 to 20 basis points in the year-over-year change rate of the core PCE deflator had originally been anticipated. In fact, however, the recalculation lowered the rate by 36 basis points – a significantly sharper decline. Three components were affected: portfolio management and advisory services, software and accessories, and legal services.
Interest Rate Increase Probability in October Falls to 38 Percent
The weaker inflation data led to an immediate reassessment of interest rate expectations. The probability of a rate increase at the upcoming FOMC meeting on October 27-28, 2026 fell from 51 percent prior to the data release to 38 percent afterwards, according to the CME FedWatch Tool. Goldman Sachs shifted their forecast for the next rate move from October to December 2026. Some analysts even consider it possible that further rate increases could be avoided altogether.
The Federal Reserve had raised the federal funds rate by 0.25 percentage points to 3.75 to 4.00 percent on September 16, 2026 – the first increase since July 2023. The vote was unanimous at 12-0. The Dot Plot released in September – a summary of the interest rate projections of FOMC members – shows a median of 4.1 percent by year-end 2026. At least 16 of 18 participants expect at least one additional rate move through year-end.
Oil Prices and Geopolitics Drive Yields to Record Levels
The high bond yields stand in contrast to weaker inflation and are driven by other factors. Jim Reid of Deutsche Bank called the current phase "a difficult quarter" and pointed to renewed escalation in the US-Iran conflict as a key driver of market tensions. Brent crude rose 42.0 percent from its lows in late June 2026 – a move that triggered a massive global bond selloff.
10-year Treasury yields rose for seven consecutive months for the first time since 2011. The US and Iran made only limited progress in negotiations despite early signs of recovery in Middle East supply flows. In addition to oil prices, stronger-than-expected US economic growth is also cited as a driver of yield increases, which fuels expectations of further monetary policy tightening.
What Investors Need to Know Now
The next FOMC meeting takes place on October 27-28, 2026, with the rate decision announcement on October 28 at 7:00 PM German time – one hour earlier than usual due to different daylight saving time transition dates in Europe and the US. The press conference begins at 7:30 PM German time. However, the final meeting of the year on December 8-9 is considered more important, as the Fed will release new projections and an updated Dot Plot.
Experts at BlackRock see opportunities in the current market situation: over 80 percent of the global bond market currently offers yields above 4 percent. Financial advisors recommend that investors use the situation to rebalance their portfolios, as bonds once again represent an attractive income source. Treasury Inflation-Protected Securities (TIPS) are particularly recommended as protection against inflation rates. Money market funds are currently filled with over 3 trillion US dollars in private capital.
John Williams of the New York Fed emphasized the need for careful data analysis given the uncertain situation. Investors focused at the end of September on the Nonfarm Payrolls report from September 28, 2026, with a consensus of 90,000 newly created positions.
