The future for the S&P 500 fell 0.2% while that for the Dow Jones Industrial Average rose 0.2%.

U.S. stock indexes suffered their worst losses since 2022 after profit reports from Tesla and Alphabet helped suck momentum from Wall Street’s frenzy around artificial-intelligence technology.

In Asia, Japan's benchmark Nikkei 225 lost 3.3% to 37,869.51, its lowest close since April.

The recently strengthening yen, which has recovered from trading above 160 Japanese yen to the dollar earlier this month, hurts profits of Japanese exporters when they are brought back to Japan. Toyota Motor Corp. shares dropped 2.6%, while Sony Group's sank 5.4%.

In currency trading, the U.S. dollar edged down to 152.50 yen from 153.89 yen. The euro cost $1.0844, up from $1.0841.

The yen has been gaining against the dollar largely because of speculation the Bank of Japan will raise its near-zero benchmark interest rate soon. The central bank's next policy meeting ends on July 31.

“The major risk is that the BOJ might refuse to hike next week, causing the entire long yen trade to collapse. But that’s probably just a bad thought,” said Ipek Ozkardeskaya, a senior analyst at Swissquote Bank.

Chinese shares fell as investors questioned a central bank decision to cut another key interest rate after several similar moves earlier this week.
