The euro fell to a three-week low on Monday while the Mexican peso also came under pressure after President Donald Trump threatened to impose a 30% tariff on imports from two of the largest U.S. trading partners beginning August 1.

The EU has been a frequent target of Trump's criticism. On 2 April, he proposed a 20% tariff for goods from the bloc, as well as dozens of other trade partners. He then threatened to raise the EU import taxes to 50% as trade talks stalled.
