President Donald Trump said he would announce reciprocal tariffs on Thursday, promising to deliver on his threat to slap tariffs on imports from countries that impose higher duties on U.S. goods.

The move would represent a major escalation of his trade war with economic partners. Trump announced the move on his Truth Social platform. He did not give any details on what the tariffs would be, how they would be structured, or when they’d take effect.

“THREE GREAT WEEKS, PERHAPS THE BEST EVER, BUT TODAY IS THE BIG ONE: RECIPROCAL TARIFFS!!! MAKE AMERICA GREAT AGAIN!!!” he wrote.

The dollar trimmed losses. Currencies of economies at the heart of the trade tensions with the US immediately reacted, with the euro paring gains and the Mexican peso lagging major currencies versus the greenback so far this session. Meanwhile, haven currencies like the Swiss Franc and Japanese yen held higher, outperforming peers.

White House Press Secretary Karoline Leavitt had previously indicated that Trump was planning to announce the tariffs program before his meeting Thursday with Indian Prime Minister Narendra Modi. While Trump did not provide a specific time he planned to unveil the program, the White House has said he plans to sign executive actions at 1 p.m. Washington time, ahead of the Indian leader’s arrival at the White House.

Trump has gravitated toward the reciprocal tariff plan as a key part of his push to raise U.S. levies overall. Trump has said it would apply to nations who generally have a higher average tariff rate than the U.S., which would raise its own tariff to match them.

“Very simply, it’s: if they charge us, we charge them,” he said Sunday while speaking with reporters and confirming he planned to announce this week.

The White House has not shared details of the plan, including what it would use to calculate the tariff rate and whether other trade barriers or taxes would be considered. It hasn’t specified whether it would pick a single average for each country or differentiate by sector, or whether it will allow for exclusions.

The White House also hasn’t said when they’ll take effect, and a longer lead time will raise speculation of whether it will be used as leverage or a starting point for negotiations with world leaders.

Trump earlier announced tariffs on China, Canada and Mexico, but paused the latter two for a month after the countries made border security pledges. He has also announced tariffs on steel and aluminum that are set to take effect next month.
