Mexico’s peso and Canada’s dollar fell sharply in the early hours of Tuesday morning on the back of a social media post from president-elect Donald Trump outlining plans to impose 25% tariffs on all products imported from the two countries with which the U.S. shares a land border.

The pick of Scott Bessent as Treasury secretary has changed the market's mood, says Kit Juckes, chief currency strategist at Societe Generale. Stock futures are up, and both bond yields and the dollar are down.

The benchmark S&P 500 and the blue-chip Dow hit intraday record highs on Monday while the Nasdaq also advanced, with Scott Bessent's nomination as Treasury secretary in the incoming Trump administration boosting investor sentiment.
