Government bond yields across major economies hit their highest levels in decades on Tuesday, driven by growing concerns over inflation and geopolitical instability. The S&P 500 dropped as investors reacted to the sharp rise in yields, which signaled a potential increase in borrowing costs for governments and businesses.
The 10-year US Treasury yield climbed to its highest level since 2007, while similar increases were seen in Japan and Germany, according to The Straits Times. Investors were also watching the impact of rising oil prices, which added to inflation fears and made it harder for central banks to control price growth, according to a report from the Hindustan Times.
The lack of progress in US-Iran negotiations further fueled market anxiety, as President Donald Trump confirmed that no talks were currently underway with Tehran. Trump also emphasized that the US naval blockade against Iran remained fully in place, increasing uncertainty about regional stability and oil supply risks.
The rise in government bond yields affected stock markets globally, with semiconductor stocks among the hardest hit. Shares of Western Digital and Sandisk fell sharply, dropping nearly 7% and 8% respectively, while Home Depot helped cushion losses in the Dow Jones.
Analysts noted that the selloff in government bonds could have broader economic consequences, especially as debt levels continue to rise across developed nations. Japan’s 10-year bond yield reached its highest level in three decades, while Germany’s 30-year yield rose to its highest since 2011.
The US debt total is approaching $40 trillion, raising concerns about long-term fiscal sustainability and the ability of governments to manage rising interest costs. Some experts said that the current bond market behavior was not unexpected given the fiscal challenges facing several major economies.
In Europe, France and Britain also saw their borrowing costs climb to levels not seen in over a decade. The recent decision by the US Treasury to sell euros instead of dollars during joint intervention with Japan suggested that officials were trying to avoid worsening bond market stress.
Foreign holdings of US Treasuries declined in June, particularly in Japan, Britain, and China — the largest foreign holders of US bonds. Despite the current selloff, some investors remain optimistic about long-term trends, with one senior adviser stating that he expects the bond market to recover.
The broader economic outlook remains uncertain as investors balance inflation concerns with corporate earnings and emerging trends in artificial intelligence, Yahoo Finance reported. Long-term borrowing costs across the globe rose to multi-decade highs due to a combination of inflation fears, fiscal deficits, and surging AI-related bond issuance.
