U.S. President Donald Trump said on Wednesday that he was willing to extend the deadline for trade talks but it was not likely necessary as the U.S. will send offer letters to countries in a week or so.

However, markets were a little concerned about the European Union being able to clinch a deal before Trump's July 8 deadline - when the tariff pause expires.

Geopolitical worries added more caution to markets already navigating U.S. tariff-driven uncertainty after trade talks with China did not offer a solution to de-escalate longstanding tensions.

U.S. personnel were being moved out of the Middle East because "it could be a dangerous place" amid rising tensions with Iran, Trump said on Wednesday.
