US stocks close at lowest since June, Treasury yields spike on hawkish Fed

US stock market: Wall Street tanked in a broad sell-off on Thursday, as investor risk appetite was dashed by worries that the Federal Reserve's restrictive monetary policy will remain in place for longer than anticipated. All three major US stock indexes tumbled more than 1 per cent and benchmark 10-year US Treasury yields touched a 16-year peak the day after Fed Chairman Jerome Powell warned inflation still has a long way to go before approaching the central bank's 2 per cent target.

Interest rate-sensitive megacaps, led by Amazon.com (AMZN.O), Nvidia Corp (NVDA.O), Apple Inc (AAPL.O) and Alphabet Inc (GOOGL.O) dragged the S&P 500 and the Nasdaq to their lowest closing levels since June. On Wednesday, at the conclusion of its two-day monetary policy meeting, the central bank left the Fed funds target rate unchanged at 5.25 per cent-5.50 per cent, as expected.

But revised economic projections, including the closely watched dot plot, showed interest rates will remain elevated through next year, dampening hopes for easing of policy before 2025.

"If you do have rates higher for longer, you have more strain on the system and more pressure on the economy," said Thomas Martin, Senior Portfolio Manager at GLOBALT in Atlanta. "It gives people another chance to say that the lag time of higher rates – which we're just starting to feel – might really bite." "We’re ratcheting up the possibility that we won’t get a soft landing," Martin said, citing economic pressure from higher rates, along with student loan payments resuming, the UAW strike, a potential government shutdown, higher Treasury yields, climbing crude prices and a strengthening dollar.

An unexpected 9 per cent drop in initial US jobless claims, to the lowest level in eight months, played into the Fed's notion that the labor market remains too tight, putting upward pressure on wages, and the economy is resilient enough to withstand higher rates for longer. "Higher for longer" has become a common credo among the central banks of the world's biggest economies as global policy tightening, in order to tame inflation, reaches its peak.

"The headlines this morning were quite something when it came to central banks," Martin said. "All of them were hawkish." At 4:12PM ET, the Dow Jones Industrial Average (.DJI) fell 370.46 points, or 1.08 per cent, to 34,070.42, the S&P 500 (.SPX) lost 72.2 points, or 1.64 per cent, to 4,330 and the Nasdaq Composite (.IXIC) dropped 245.14 points, or 1.82 per cent, to 13,223.99.

All 11 major sectors of the S&P 500 lost nearly 1 per cent or more, with real estate stocks (.SPLRCR) suffering its biggest one-day percentage drop since March. Semiconductor firm Broadcom (AVGO.O) slid 2.7 per cent following a report that Alphabet-owned Google's executives discussed dropping the company as a supplier of artificial intelligence chips as early as 2027.

The Philadelphia chip index (.SOX) shed 1.8 per cent. Klaviyo Inc gained 2.9 per cent the day after its debut as a public company, while another recent IPO, Arm Holdings lost 1.4 per cent to just a dollar above its $51 offer price. Shares of FedEx (FDX.N) jumped 4.5 per cent after the package delivery company delivered a big profit beat.

Fox Corp (FOXA.O) and News Corp (NWSA.O) gained 3.2 per cent and 1.3 per cent, respectively, following news that Rupert Murdoch will step aside as chairman.

Declining issues outnumbered advancing ones on the NYSE by a 5.89-to-1 ratio; on Nasdaq, a 2.80-to-1 ratio favored decliners. The S&P 500 posted three new 52-week highs and 29 new lows; the Nasdaq Composite recorded 22 new highs and 373 new lows. Volume on US exchanges was 10.76 billion shares, compared with the 10.12 billion average for the full session over the last 20 trading days.
