The long end is doing the Fed’s tightening for it, and the move is running from Washington to Tokyo and Frankfurt at once.
The global bond market is repricing the cost of long-term money, and it is not waiting for central banks. The 10-year Treasury yield closed at 5.18% on September 24, its highest close since July 2007, according to the US Treasury’s daily par yield curve.
The move was fast. The 10-year closed at 4.96% on September 21, so it added 22 basis points in three sessions before settling at 5.17% on September 25. The 30-year ended that week at 5.49%.
It was not only an American story. Japan’s 10-year government bond yield closed at 3.071% on September 24 and September 25, the highest since September 1996, according to Japan’s Ministry of Finance. Germany’s 10-year Bund yield reached 3.63% on September 25, a level last seen in April 2011, based on Bundesbank data.
The long end, not the Fed, is doing the work
The shape of the move matters more than the level. The 2-year Treasury yield, the part of the curve most tied to Federal Reserve policy, rose just 5 basis points between September 21 and September 25, to 4.81%. The 10-year rose 21 basis points over the same stretch.
That is a term-premium story. Investors are demanding more to lend for a decade, not simply pricing a higher policy rate.
The Fed has already moved. On September 16 the Federal Open Market Committee voted 12-0 to lift the federal funds target range by a quarter point to 3.75% to 4%, its first increase since 2023. The median projection from policymakers puts the rate at 4.1% at the end of 2026, which implies one more quarter-point rise this year.
Energy is the fuel
The inflation backdrop explains why bond buyers want compensation. US consumer prices rose 3.4% in the 12 months to August, and the energy index rose 16.3%, the Bureau of Labor Statistics reported on September 11. Core prices, which strip out food and energy, rose 2.4%.
Diesel is the sharpest pressure point. The average US retail price reached $6.529 a gallon in the week of September 21, the highest in Energy Information Administration records and up from $3.749 a year earlier. The previous weekly record was $5.81, set in June 2022.
Crude has already come off its peak, and yields rose anyway. Brent spot fell to $114.89 a barrel on September 22 from $130.80 on September 15, according to EIA data. A bond market that sells off while oil eases is pricing persistence, not a single shock.
The Fed’s own forecasts assume the pressure fades. Policymakers project PCE inflation of 3.7% for 2026, falling to 2.3% in 2027.
What comes next
Two releases will test that forecast. The Bureau of Economic Analysis publishes August personal income and outlays, including the PCE price index the Fed prefers, on September 30. The Bureau of Labor Statistics releases the September employment report on October 2.
A hot print on either would support the Fed’s signalled further hike. For borrowers, the damage is already done: mortgages, corporate bonds and government debt all price off the long end, and the long end now sits at levels last seen before the financial crisis.
