Global Debt Crisis Pushes Borrowing Costs to 40-Year Highs as Russia's War Deficit Doubles to $81 Billion

Governments around the world are facing a double crisis: soaring debt and rapidly rising borrowing costs. A global selloff in government bonds has pushed yields—the interest rate investors earn from a bond—to levels not seen in decades, forcing countries to pay far more to borrow money [254686][254560].

The 10-year U.S. Treasury yield, a key benchmark that influences mortgages, corporate loans, and other debt worldwide, reached its highest level since 2002, marking a 23-year peak, before pulling back [254560][254707]. The surge came as a global bond selloff spread from European markets, highlighting growing pressure in debt markets [254707].

Oil prices are one driver of the crisis. Higher oil prices feed inflation, and inflation pushes interest rates up [255867]. But government debt is the deeper problem. Many countries now carry heavy borrowing loads, and investors worry these governments may struggle to repay, so they demand higher returns to hold their bonds [255867].

In the United Kingdom, the yield on 30-year government bonds—known as gilts—hit 6% for the first time in decades. The British pound fell sharply as investors moved money to safer assets, and the Bank of England faces a difficult choice between raising rates to defend the currency or risking a deeper economic slowdown [254688].

France is also under pressure. The country's public debt reached more than $4 trillion in June, exceeding the size of its economy. Student protests have exposed France's growing financial problems as the government tries to reduce a rapidly growing budget deficit [256349]. French bond yields climbed again after a brief relief rally, signaling that investors remain unconvinced the country's financial problems are solved [255969].

Japan is facing similar skepticism. The government offered its highest interest rate on 30-year bonds in roughly 30 years, yet investors barely responded. Yields rose anyway, meaning investors demanded even more return before committing their money. Japan carries the world's largest government debt burden, and with the Bank of Japan slowly stepping back from buying massive amounts of government bonds, the market must absorb more debt on its own—and demand looks weak [256839].

Meanwhile, Russia's 2026 budget deficit has nearly doubled to more than $81 billion as war spending has blown past the original plan. The surge follows President Vladimir Putin's assessment that talks with the United States in Alaska would not produce an acceptable deal to end the fighting [257034].

The euro has dropped to its lowest level in 17 months against the U.S. dollar, with political instability and worries about French debt making investors nervous [255557]. The International Monetary Fund (IMF) has warned that high energy prices could stay high even after the Gulf conflict ends, suggesting continued pressure on businesses and households [256222].

The impact reaches far beyond trading floors. Higher government borrowing costs typically raise interest rates on mortgages, credit cards, and business loans, making it more expensive for households and companies to borrow worldwide [254686]. Markets remain unsettled as investors wait for signals from the U.S. Federal Reserve and the European Central Bank on their next moves [254686].
