Global Bond Yields Hit Multidecade Highs Amid Debt Worries
Bond yields show how much governments and other borrowers must pay investors for loans.
Yields have risen in several major countries.
Higher oil prices are making people worry that inflation could stay high.
That could mean interest rates remain high for longer.
Governments are also borrowing more money and must pay more to refinance old debt.
Five large technology companies have issued $220 billion in debt this year to fund artificial-intelligence projects.
Higher borrowing costs can make mortgages, car loans and business financing more expensive.
This can reduce spending and investment and may slow economic growth.
Central banks can sometimes buy bonds during severe market stress, but officials have warned that intervention should not be expected simply to stop a selloff.
Bond yields rose across the United States, France, Britain, Japan and India to multidecade highs.
Renewed oil-price gains linked to US-Iran tensions are increasing inflation concerns and expectations of higher-for-longer interest rates.
The US national debt has exceeded $40 trillion, while debt-to-GDP ratios are at least 100% across most G7 economies.
India's 10-year government bond yield rose three basis points to 7.2133%, its highest since April 2024.
Heavy borrowing by governments and major technology companies is increasing bond supply and putting further pressure on yields.

Intervention Could Stabilize Markets
Central banks can buy government bonds during severe market stress, and the European Central Bank has a mechanism for an unwarranted or disorderly rise in borrowing costs.
Intervention Should Be Limited
