Katrina Ell, a senior economist at Moody's Analytics, stated that Trump's announcement of tariffs on major trading partners on social media serves as a reminder of the significant volatility his presidency may cause in the markets. She mentioned that, in fact, there was no preparation before Trump announced the policies, which has created a lot of anxiety in the markets. It is unknown what will ultimately happen. No one can determine the timeline for the fulfillment of Trump's campaign promises. However, it is certain that we are heading towards a high degree of uncertainty. There is hope that if countries like Mexico and Canada can resolve issues to some extent, trade tensions may ease. If they choose to display strength, the situation may escalate, and Trump will double down, resulting in greater ripple effects on other economies.
