US Stocks Drop as Yields Extend Surge

2026-09-15 20:06 By Isabela Couto 1 min. read

US stock indices closed lower on Tuesday under continued pressure from higher bond yields.

The S&P 500 fell 0.4%, the Dow shed 328 points and the Nasdaq lost 0.6%.

The benchmark 10-year Treasury yield hit its highest level in nearly two decades.

Escalating Middle East strikes worsened the outlook for regional energy supplies, increasing inflation risks and the prospect of a hawkish Federal Reserve response.

Markets expect the Fed to hike rates by 25 bps tomorrow as higher fuel prices have driven inflationary pressures this year.

Losses were broad-based, with credit-sensitive AI hyperscalers hit by rising borrowing costs.

Alphabet shed 1.3%, Microsoft lost 1.6%, Oracle tumbled 3.1% and Amazon retreated 2%.

Chipmakers were mostly higher following Monday’s selloff, when Anthropic CEO Dario Amodei called for slower AI development to mitigate risks from increasingly capable models.

Nvidia added 0.6%, while AMD rose 2.2%.
