U.S. debt is becoming more expensive because interest rates on U.S. debt are going up. The U.S. has to pay more to maintain the debt. Trump’s trade wars, and his continuation and growing of U.S. deficits, are causing this. Trump’s erratic tariff behavior causes uncertainty and discourages investment.
Dollar dominance is a benefit to Americans. Even individuals could borrow cheaper because the U.S. dollar was the global reserve currency. The dollar losing its value hurts this benefit. Trump’s tariffs weakened U.S. dollar dominance by losing trust in the United States as a responsible leader.
The U.S. didn’t primarily lose some manufacturing due to the strength of the dollar.
U.S. problems are worse than just Trump. There are a lot of bad political ideas on both sides.
The fall of the U.S. dollar relative to other currencies will make imports more expensive. This increases the costs of imports on top of the more direct effect of tariffs.
The dollar’s decrease will make U.S. exports cheaper overseas, however, this may be counteracted by foreign countries retaliating against U.S. exports in response to Trump tariffs, and by foreign customers boycotting U.S. companies.
The independence of the Fed is key to protecting the dollar, the economy, and price stability. People can trust in the dollar because the Fed will do what needs to be done to control inflation, even if it is painful.
Big things Trump’s economic team wants to do would require great international deals, but those deals are worthless if no one trusts the United States or its president. Trump is so erratic, that no one trusts him. He made the NAFTA 2.0 agreement with Mexico and Canada during his first term, then during his second called it junk and tried to break it. He threatens to take territory from allies and threatens to renege on NATO promises. Countries won’t make the sacrifices of a big Trump-pushed-for-deal when they can’t trust Trump to keep his promises.
