A surge in government bond yields is sending ripples across global markets, forcing investors to reassess equity valuations amid a potential spending crunch.
A surge in government bond yields is sending ripples across global markets, forcing investors to reassess equity valuations amid a potential spending crunch.

The 10-year U.S. Treasury yield surged to a 52-week high of 4.6% on Monday, as rising oil prices and a resilient economy fueled concerns that the Federal Reserve will keep interest rates higher for longer. The move extended a sharp sell-off in government bonds from last week, with the 30-year Treasury yield also hitting its highest level in nearly a year. The spike in borrowing costs weighed on equities, pulling the tech-heavy Nasdaq Composite down 0.5%.
"If bond [volatility] rises with rising back-end rates, we would expect the first meaningful correction in equity prices since markets bottomed," Mike Wilson, a strategist at Morgan Stanley, wrote in a note on Monday. Wilson, who has a year-end target of 8,000 for the S&P 500, said the level to watch is 4.5% on the 10-year Treasury note yield, a level that was breached on Monday.
The benchmark 10-year yield, which influences interest rates on mortgages and other consumer loans, climbed as high as 4.61% on Monday. The move came as West Texas Intermediate crude futures rose 0.8% to $106.30 a barrel, and after government data last week showed inflation accelerated to 3.8% in April, its highest annual reading in nearly three years.
The sustained rise in yields threatens to increase borrowing costs for companies and consumers, potentially slowing economic growth. For the stock market, higher yields make less-risky bonds more attractive relative to equities, and can particularly pressure the valuations of growth-oriented technology stocks whose earnings are further out in the future.
The recent spike in Treasury yields is closely tied to a surge in oil prices, which have been driven higher by geopolitical tensions. President Donald Trump’s recent comments on Iran have added to market uncertainty, with West Texas Intermediate futures, the U.S. crude oil benchmark, recently up 0.8% to $106.30 a barrel.
"The current issue is not a lack of liquidity, but rather that capital is waiting for clearer direction from geopolitical developments, U.S. rate expectations, and upcoming regulatory signals," Bitunix analyst Dean Chen said in written commentary. "If tensions in the Middle East escalate further, or if Treasury yields continue climbing, volatility across global risk assets could accelerate sharply once again."
The technology sector, which has been a key driver of the stock market's gains this year, has been particularly vulnerable to the rise in bond yields. The Nasdaq Composite fell 0.5% on Monday, with shares of Magnificent Seven companies finishing mixed.
Memory stocks were among the biggest decliners, with Seagate Technology Holdings, Sandisk, Micron Technology, and Western Digital all down between 5% and 7%. The declines followed comments from Seagate's CEO about the challenges of expanding production capacity.
