Global Bond Sell-Off Pushes Japan Yields To 30-Year High
Government bonds are loans that investors give to countries.
When investors sell those bonds, their prices fall and their yields rise.
Japan’s 10-year bond yield reached 3%, a level not seen since 1996.
Yields also rose sharply in the United States and several European countries.
Experts say large government deficits, rising debt, inflation and higher oil prices are contributing to the selling.
Technology companies borrowing heavily for artificial-intelligence projects may be adding to the pressure.
Higher yields can make stocks and other investments more unsettled.
Investors are watching upcoming inflation data and central-bank decisions.
The article says volatility could be especially high in mid-September.
Japan’s 10-year bond yield reached 3% on September 1, its highest level since 1996.
Yields also climbed to multi-decade highs in the United States, Germany, the United Kingdom and France.
Analysts linked the sell-off to government deficits, rising debt, inflation concerns and higher oil prices.
Big technology companies’ borrowing to fund artificial-intelligence spending has added pressure across bond markets.
Investors are watching the Federal Reserve, US Treasury operations and Bank of Japan meetings for signs of further volatility.
