But shares in TSMC, the world's largest contract chipmaker have slipped, after US President Donald Trump said he would announce a tariff rate on imported semiconductors over the next week. He did add however, that there would be flexibility on some companies in the sector.

In a Truth Social post on April 9, Trump said: “This is a GREAT time to move your COMPANY into the United States of America, like Apple, and so many others, in record numbers, are doing. ZERO TARIFFS, and almost immediate Electrical/Energy hook ups and approvals. No Environmental Delays. DON’T WAIT, DO IT NOW!”
