Stock futures are little changed as investors monitor Trump tariff developments: Live updates

Stock futures were little changed Tuesday night as investors monitor the latest tariff updates from President Donald Trump.

Futures tied to the Dow Jones Industrial Average added just 16 points, or 0.04%. S&P 500 futures rose 0.05%, while Nasdaq 100 futures gained 0.1%.

Traders were on guard during Tuesday's regular session as Trump rolled out new updates to his tariff policy.

The S&P 500 inched down just 0.07%, while the tech-heavy Nasdaq Composite added 0.03%. The 30-stock Dow lost nearly 0.4%. Global stock markets, in particular the Nikkei 225 in Japan and South Korea's Kospi and Europe's Stoxx 600 index, posted modest gains just a day after Trump announced sharp tariffs on 14 countries.

On Tuesday, Trump said in a Truth Social post that there would be no change or extensions on the raft of duties he announced on those nations, which include Japan and South Korea. The new tariff rates range from 25% to 40% and are set to begin on Aug. 1.

Trump on Tuesday also announced a 50% levy on copper imports and hinted that further sector-specific tariffs will soon be announced. He threatened Tuesday afternoon to impose up to 200% tariffs on pharmaceuticals imported into the U.S., but said that he will "give people about a year, year and a half" until the duties go into effect.

"The tariff announcement was a reminder that markets are not out of the woods. The White House has not really achieved their goals on trade, and that could be a continued source of volatility," said Scott Helfstein, Global X head of investment strategy.

In addition to watching further tariff policy developments on Wednesday, traders will be monitoring the release of the Federal Open Market Committee's minutes from its last meeting.
