Washington (United States) (AFP) - The US trade deficit in July widened to its largest since March 2025, government data showed Thursday, as imports climbed on the back of the booming AI tech build-out.

US trade has seen wide fluctuations since President Donald Trump returned to the White House last year and rolled out sweeping tariffs on allies and competitors, in efforts to narrow the trade gap.

But the trade deficit in the world’s biggest economy grew to $88.6 billion in July – a 24.4 percent increase from the month prior – as exports of crude oil and gold fell while imports of tech products jumped.

Exports dipped 2.1 percent to $310.7 billion, the Department of Commerce said.

Imports rose 2.8 percent to $399.3 billion, bolstered by computers, computer accessories and semiconductors.

The US deficit with Taiwan, a major manufacturer of chips, reached a record $20.7 billion for the month.

The trade gaps with Mexico, Vietnam, Thailand, South Korea and Malaysia meanwhile also hit their highest on record.

While Trump’s tariffs have hit economies representing the majority of US trade, American officials have been careful to exempt products like chips, smartphones and other types of electronics.

Washington is looking to develop new tariffs on semiconductors, Commerce Secretary Howard Lutnick told CNBC Wednesday, adding that tech giants are aware of the Trump administration’s intent.

“What you’re going to see is targeted, thoughtful tariff policy that basically says if you build here, you don’t pay,” Lutnick said.

Over the past year, businesses have scrambled to step up imports before new waves of US duties kicked in.

Some firms expect further challenges in managing through Trump’s policies, which have caused business costs to rise, according to services sector survey data from the Institute for Supply Management. Activity in the sector jumped in August.

Although the US Supreme Court struck down many of Trump’s global tariffs in February, officials in July replaced them with fresh duties targeting 60 trading partners.

A separate trade investigation taking aim at 16 partners including China, the European Union and Taiwan, could lead to a further round of tariffs.

The United States meanwhile is engaged in a trade war with neighboring Canada, with which its deficit narrowed in July. Last month, Trump slapped a 50-percent duty on billions of dollars in Canadian goods, prompting Ottawa’s planned retaliation.

Also weighing on trade flows is fallout from the Middle East war, with Iran largely blocking off the Strait of Hormuz – a key waterway for global energy and fertilizer transit.
