Traders around the world are preparing for greater volatility.

As Trump's latest remarks on tariffs made headlines, Nick Twidale's phone kept ringing, and he even spilled a cup of white coffee on his keyboard.

After Trump's social media post on Monday drove the dollar to soar, this veteran with 26 years of forex trading experience at AT Global Markets said, "Social media posts like this are popping up again, this familiar feeling is ominous, but muscle memory is kicking in." Twidale stated, "The good news is that under Trump's administration, there will be many opportunities to make money in the next four years"; he profited from short positions on the Mexican peso and the australian dollar.

For traders preparing for Trump's return and the accompanying market volatility, this is increasingly becoming their hope.

The elected president promised on the social media site Truth Social to impose more tariffs on a series of countries including Mexico, marking the first specific threats on trade since he won the election on November 5, as investors witnessed the taste of such market volatility.

Trump threatened to impose a 25% tariff on products from Mexico and Canada, causing the exchange rates of the two currencies against the dollar to drop by 1%, exacerbating the daily $7.5 trillion in volatility.

After the news of the tariffs broke, traders and analysts in New York rushed to their computers. Among them was barclays strategist Erick Martinez Magana, who had been advising clients to consider going long on the dollar and shorting the Mexican peso.

Magana stated that Trump's changes to immigration and tariff policies are serious and that Mexico is the direct target. He expects the Mexican peso to depreciate further against the US dollar towards 21.50. During Tuesday's trading session, it was about 20.50.
