Global bond yields hit highest since 2008 amid oil surge past $100

Long-dated government bond yields around the world have climbed to their highest levels since the 2008 financial crisis, driven by a surge in oil prices past $100 a barrel after escalating military conflict in the Middle East reignited inflation fears and forced a broad repricing of rate expectations.

Oil Shock Drives the Selloff

Brent crude topped $100 a barrel on Thursday for the first time in two months after Houthi attacks on tankers in the Red Sea opened a new front in the conflict, while President Donald Trump threatened to extend U.S. strikes on Iran. The global benchmark rose roughly 14% this week alone, with West Texas Intermediate trading near $92.energyconnects+1

The oil rally has fed directly into the bond market rout. The U.S. 30-year Treasury yield stood at 5.14% on July 24, according to Trading Economics, its highest level since 2007. The 10-year yield reached 4.67% the same day. According to data from the Federal Reserve, the effective federal funds rate remains at 3.63%, with the discount window primary credit rate at 3.75%.tradingeconomics+3

The average yield on sovereign debt maturing in 10 years or more has now reached its highest since July 2008, according to Bloomberg data cited by market analysts. The global long-duration bond index has fallen 4.6% in 2026 after being up 3% through the end of February.equiti

Inflation Fears and Rate Hike Expectations

The New York Fed's June consumer survey showed one-year inflation expectations rising to 3.7%, the highest since September 2023. The Consumer Price Index rose 3.5% year-over-year in June, down from 4.2% in May but still well above the Fed's 2% target.reuters+1

Bank of America ↗ 0.21% has forecast three consecutive 25-basis-point rate hikes in September, October, and December, which would lift the federal funds rate to 4.25%-4.50%. Deutsche Bank ↗ 0.32% similarly expects two hikes before year-end. Rate futures markets have priced in at least one hike by early autumn and another in 2027.interactivebrokers+2

A Bank of America survey in May found that 62% of global fund managers expect 30-year Treasury yields to reach 6%, which would be the highest since late 1999.wsj+1

A Broad Global Repricing

The selloff extends well beyond the United States. Long-dated UK gilts have climbed to levels not seen since 1998, making Britain the highest-yielding developed bond market at the 30-year tenor. Japan's 30-year yield also hit a record earlier this year, while Germany's long-dated bund yields have risen sharply.cnbc+1

Strategists warn the repricing may have further to run. "If Red Sea traffic is minimal, then we would forecast $120, kind of the inflection point for oil," said Jay Hatfield, chief executive at Infrastructure Capital Management. Until a credible de-escalation in the Middle East materializes or growth expectations shift downward, analysts say long-dated bonds are likely to remain under pressure.equiti+1
