Global government bond yields are pressing toward 4% for the first time since 2007, driven by a sharp Treasury selloff. Strong U.S. economic data, stubborn inflation, and mounting rate-hike expectations pushed the benchmark 10-year yield to 5.139% on Thursday, marking its highest level in nearly two decades.
A deepening selloff across international debt markets is pushing borrowing costs to multi-decade highs, fueled by mounting market speculation that central banks will keep interest rates elevated to combat inflation. The average yield on global government debt closed in on 4%—a threshold last recorded in 2007—after Bloomberg’s Global Aggregate Treasuries index climbed eight basis points to 3.99% on Wednesday. Expectations that borrowing costs will remain elevated for an extended period are being reinforced by persistent inflation, robust economic indicators, and rising fiscal anxieties, with Treasuries acting as a primary catalyst for the downturn.
U.S. Treasury Yields Hit Multi-Decade Highs
As market participants increasingly anticipated an additional interest rate increase by the Federal Reserve, Treasury yields surged to multi-decade peaks during the early hours of Thursday. Reaching its highest mark since July 2007, the yield on the benchmark 10-year Treasury note—which influences mortgage rates—climbed to 5.139% on Thursday morning. Short-term and long-term notes saw similar upward pressure. The 2-year note climbed to 4.897% for its highest reading since 2023, while the 30-year Treasury yield advanced more than 3 basis points to reach a post-2004 peak of 5.438%. One basis point equals 0.01%, and yields and prices move in opposite directions.
Government debt markets outside the United States felt the strain as well amid a global government bond selloff. In Japan, the 10-year Japanese Government Bond yield climbed 8 basis points to 3.055%, reaching its highest level since August 1996. European sovereign debt also experienced upward pressure, as yields across various regional bonds climbed to new multi-year peaks alongside increases in U.K. Gilts and German Bunds. The downward slide in Treasuries was catalyzed by several developments, including elevated crude prices, hawkish remarks from a Federal Reserve policymaker, and U.S. economic performance that exceeded projections.
Strong Economic Data and Rising Oil Prices Fuel Rate-Hike Bets
September data published Wednesday by S&P Global revealed that the services purchasing managers’ index climbed to 58.7, marking its highest level in nearly five years. Its manufacturing counterpart was up to 56.7, a level not seen in over four years. That compares to a roughly 49% probability just a week ago.

Energy markets added further upward pressure on inflation expectations as oil prices rose sharply. International Brent crude saw an increase of approximately 2.8% to reach $105.95 per barrel, while West Texas Intermediate crude advanced 2.2% to settle at $94.40.
Federal Reserve Officials Signal Further Policy Adjustments
Michael Barr, a member of the Fed’s Board of Governors, said in a speech on Wednesday that further policy adjustments
are likely to come to bring inflation down to target. Speaking in London on Thursday, New York Federal Reserve President John Williams stated that anticipating another increase in interest rates from the Fed before the conclusion of the year would be a “reasonable” expectation.
The main driver was a strong batch of PMIs, along with a rebound in oil prices, which both led to mounting speculation about faster rate hikes,
Deutsche Bank analysts said of the Treasurys selloff in a note Thursday.
So [PMI results] played into the narrative of resilient growth, which in turn would enable the Fed to keep hiking rates to deal with inflation,
they added.
In anticipation of further clarity regarding the health of the U.S. economy, market participants on Thursday will monitor the release of figures covering August new home sales alongside weekly jobless claims data.
