Yields on the 30-year U.S. Treasury and government bonds across the world rose to multiyear highs as investors fret about inflation, deficits and A.I. spending.
Investor angst over stubborn inflation, unsustainable government deficits and rampant spending on artificial intelligence helped send borrowing costs to multiyear highs across the world this week.
The yield on the 30-year U.S. Treasury bond rose on Tuesday to 5.3 percent, its highest level since 2007. Similar bonds in Canada, Japan, Germany and elsewhere also traded at their highest yields in at least a decade.
