BlockBeats News: On November 26th, Katrina Ell, Senior Economist at Moody's Analytics, stated that Trump's announcement on social media of tariffs on major trading partners is a reminder of how much volatility his presidency could cause in the market. She said that in fact, there was no preparation before Trump announced the policy, which caused great anxiety in the market. We don't know what will ultimately happen. No one can determine the timeline for fulfilling Trump's campaign promises. But what can be certain is that we are moving towards a high degree of uncertainty. People hope that if countries such as Mexico and Canada solve the problem to some extent, trade tensions may ease. If they choose to showcase their strength, things will escalate and Trump will double his bet, which will have a greater chain reaction on other economies. (Golden Ten)
