Katrina Ell, senior economist at Moody's Analytics, said Trump's announcement on social media of tariffs on major trading partners was a reminder of how volatile his presidency could be for the market. She said the fact that there was no preparation before Trump announced his policies created a lot of anxiety in the market. We don't know what will happen in the end. No one can be sure when Trump's campaign promises will be fulfilled. But what is certain is that we are heading towards a high level of uncertainty. People hope that if countries like Mexico and Canada resolve the issue to some extent, trade tensions may ease. If they choose to show strength, things will escalate and Trump will double down, which will have a greater chain reaction on other economies. (Jinshi)
