Wall Street’s main equity indices, which had already gained more than 2% on Tuesday, jumped again on Wednesday.
“‘Buy America’ is back in action,” said Briefing.com analyst Patrick O’Hare, noting that the actions of the Trump administration would determine if that remained the case.
European stock markets also rallied, with Frankfurt gaining more than 3%.
Meanwhile, data showed that business activity in the eurozone remained “broadly unchanged” in April as manufacturing held up in the face of US tariffs despite waning confidence for the year ahead.
In Britain, however, the purchasing managers’ index tumbled more than expected to a two-and-a-half-year low.
Further comments by Trump on Tuesday indicating a more conciliatory approach to the trade war with China, added to the positive market sentiment.
Washington has imposed tariffs of 145% on a range of products from China, while Beijing has replied with 125% duties on imports from the United States.
Trump acknowledged that the US levies were at a “very high” level and that it would “come down substantially”.
That came after Treasury Secretary Scott Bessent told a closed-door event in Washington that he expected a de-escalation soon in the United States’ tariff standoff with China.
He confirmed on Wednesday, however, that trade talks with China were not currently under way and ruled out a unilateral tariff cut by the United States.
Gold, which had hit a record high above $3500 Tuesday on a rush to safety, retreated to around $3300 an ounce, while the dollar clawed back some of its recent losses against the pound, euro and yen.
“Looking at the dollar’s more muted reaction, you get the feeling that it is more of a reluctant view that Trump is slowly backing down on trade tariffs. It is actions that count,” said City Index and FOREX.com analyst Fawad Razaqzada.
In Asia, Hong Kong stocks surged on the back of a rally in tech firms including Alibaba and Tencent, and Tokyo’s stock market also gained.
Taipei jumped more than 4%, helped by a 7% surge in chip titan TSMC.
In company news, shares in Tesla jumped around 8% after Elon Musk said he would significantly scale back his Trump administration work to focus on the electric vehicle maker, which reported a 71% drop in first-quarter profits.
