Global Bond Yields Hit Multi-Decade Highs as Iran War Fears Drive Oil Surge and Market Sell-Off
Government bond yields across the US, UK, France, Germany, and Japan have risen to their highest levels since the 2008 financial crisis or earlier, driven by investor concern over the Iran conflict and its effect on inflation. US 30-year Treasury yields reached their highest level since 2007, and Japan's 10-year yield hit a three-decade peak. Oil prices climbed to a near three-week high as hopes for a US-Iran peace settlement faded, with Iran reportedly threatening to go 'fully offensive.' Wall Street indexes slipped as oil rose. Gold fell as bond yields and oil commanded investor attention. Foreign holdings of US Treasuries declined in June, led by Japan, the UK, and China. The Financial Times also flagged heavy bond issuance tied to AI financing as an additional pressure on bond markets.

Why It Matters
Rising bond yields mean the US government — and governments across Europe and Japan — pay more to borrow, costs that ultimately filter through to taxpayers and public services. For ordinary Americans, higher Treasury yields push up interest rates on mortgages and credit cards, tightening household finances even without any action by the Federal Reserve, which a Reuters poll of economists indicates is expected to hold rates steady through this year. Higher oil prices simultaneously raise costs at the pump and across supply chains, feeding the inflation that is already spooking bond markets. The sell-off cuts across borders — markets worldwide repricing inflation risk tied to the Iran conflict, with no single country's fiscal position driving the move.
