Global investors are heading into U.S. President Donald Trump's Wednesday deadline for trade tariffs palpably unexcited and prepared for a range of benign scenarios that they believe are already priced in.

White House officials have suggested that the deadline could be postponed for some countries, while others could receive a letter outlining new tariffs.

The U.S. and the European Union have not yet struck a trade deal with just days to go before Trump's tariff reprieve is set to end.

President Donald Trump said letters will now go out on Monday to 12 countries with a final "take it or leave it" offer on tariff negotiations, pushing the date forward by two days.

WASHINGTON (Reuters) -U.S. President Donald Trump said on Friday his administration later in the day will begin sending letters to 10 to 12 countries informing them of the tariff rate their products will face in the United States.

Acknowledging the complexity of negotiating with over 170 nations, Trump told reporters before departing for Iowa on Thursday that the letters will be sent to 10 countries at a time, laying out tariff rates such as 20% to 30%.
