A broad global bond market sell-off intensified on Tuesday, pushing government borrowing costs sharply higher across the United States, Europe and Asia.
The move came as investors reacted to escalating military tensions in the Middle East, rising energy prices and increasingly hawkish expectations for major central banks.
As a result, sovereign bond yields climbed to levels not seen in years across several major economies.
U.S. Treasury Yields Surge
U.S. Treasury yields rose across the curve as traders reassessed the outlook for Federal Reserve policy and inflation.
The two-year Treasury yield climbed to around 4.354%, briefly reaching its highest level since 2025. Short-term bonds came under pressure as markets priced in a more restrictive interest-rate outlook.
Meanwhile, the 10-year Treasury yield advanced to approximately 4.780%, also reaching its highest level since 2025.
The 30-year Treasury yield increased to around 5.273%, reaching its highest level in more than a week as investors demanded greater compensation for holding longer-duration government debt.
European Bond Yields Climb Sharply
Selling pressure was also widespread across European government bond markets.
Germany’s two-year Schatz yield rose for a fifth consecutive session, reaching approximately 2.936%. This marked its highest level since July 2024.
The German 10-year Bund yield climbed to around 3.352%, while the 30-year yield reached approximately 3.841%. Both moved to their highest levels since 2011.
France also faced higher borrowing costs, with the 10-year government bond yield rising to around 4.15%, its highest level since November 2008.
Japan Bond Yields Reach Historic Levels
Japan’s government bond market also experienced significant selling pressure.
The benchmark 10-year Japanese government bond yield briefly reached 3.000%, its highest level since late 1996.
At the same time, the two-year JGB yield climbed to around 1.800%, setting a record high.
The moves highlight the growing pressure on Japanese bond markets as investors increasingly expect tighter monetary policy from the Bank of Japan.
Bonds Lose Some Safe-Haven Appeal
The global bond rout reflects an important change in investor behavior.
Government bonds have traditionally been viewed as safe-haven assets during geopolitical crises. However, investors are currently selling sovereign debt as concerns over inflation and interest rates outweigh demand for safety.
Rising energy prices are a major part of that shift.
Higher oil prices could keep headline inflation elevated, increasing the risk that central banks will maintain restrictive monetary policies for longer than previously expected.
Middle East Conflict Pushes Oil Above $90
Escalating military tensions between the United States and Iran have contributed to the pressure on global markets.
Military strikes and retaliatory attacks in the Persian Gulf region have pushed crude oil prices above $90 per barrel.
Higher energy prices can quickly feed into transportation, manufacturing and consumer costs.
For bond investors, that raises concerns that inflation could remain elevated well into 2027.
As a result, investors are demanding higher yields to compensate for the increased inflation risk associated with longer-term bonds.
Fed Rate Expectations Turn More Hawkish
The bond sell-off accelerated following comments from Federal Reserve Chair Kevin Warsh at Jackson Hole.
Warsh indicated that policymakers still have more work to do to bring inflation under control.
Following his remarks, money markets increased expectations for another Federal Reserve rate increase.
Traders priced the probability of a 25-basis-point rate hike in September at roughly 60%.
That shift in expectations placed additional pressure on short-term U.S. Treasury securities.
ECB and Bank of Japan Also Face Pressure
The Federal Reserve is not the only central bank facing growing inflation concerns.
Markets are also watching the European Central Bank, which is expected to consider another interest-rate increase at its Sept. 10 meeting.
Meanwhile, the Bank of Japan is facing pressure to tighten monetary conditions as domestic bond yields continue to rise.
Expectations of tighter monetary policy across several major economies are adding to the global pressure on sovereign debt markets.
Rising Government Debt Adds to Bond Supply
Government borrowing is another major factor behind rising yields.
Countries around the world are issuing large volumes of debt to finance defense spending, infrastructure projects, energy-transition programs and widening budget deficits.
Japan, for example, has proposed a record fiscal budget request of around 143 trillion yen.
France is also dealing with increasing concerns over its public debt burden.
At the same time, major central banks continue to reduce their balance sheets through quantitative tightening.
That means private investors must absorb a greater share of newly issued government debt.
When demand fails to keep pace with supply, bond prices fall and yields rise.
Inflation and Jobs Data Could Drive the Next Move
Bond traders are now turning their attention to upcoming economic data for clues about future central bank policy.
Eurozone inflation figures for August are expected to provide more information about whether underlying price pressures remain persistent.
Stronger-than-expected inflation could reinforce expectations for additional ECB tightening.
In the United States, investors are also watching the July JOLTS job openings report.
Friday’s nonfarm payrolls report will be particularly important, as it will provide one of the final major labor-market signals before the Federal Reserve’s Sept. 16 policy decision.
With bond markets experiencing sharp moves across multiple regions, upcoming inflation, employment and central bank developments could determine whether the global sell-off continues.
