Why is the market not afraid of Trump's pressure on Powell recently?

Around April 20, Trump threatened to fire Powell, leading to a second market crash in stocks, bonds, and currencies. In late June, Trump began pressuring Powell to cut interest rates, and rather than panicking, the market seemed to be subtly excited.

In addition to a more stable market mentality, I personally understand that there are deeper reasons: firing Powell would actually undermine the independence granted to the Federal Reserve by U.S. law (challenging the constitutional system). Now, whether it's pressuring Powell, encouraging Federal Reserve Board members to publicly support rate cuts, or determining the next Federal Reserve Chair in advance, all of this is part of a political game within the constitutional and legal framework, which is completely justified.

As long as Trump no longer attempts to undermine the U.S. constitutional system or arbitrarily change the Constitution, the market will subconsciously believe that the U.S. system still exists and has the ability to self-correct, thus the state of chaos is still a long way off.
