The US GDP is better than expected, which will increase the market's confidence in economic growth. This is correct. As a safe-haven currency, if the world economy grows strongly, do you still need to hedge? People will not buy dollars to hedge, but buy high-interest currencies with high risks and high returns.

When the world economy is improving, risk aversion is seriously declining. People will not invest in dollars, but invest in gold and Australian dollars.

Only when the world economic crisis, high risk aversion, the dollar as a hedging tool, people will invest in the dollar, which led to a higher dollar.

This is the same reason that the US stock market is higher and the dollar is suppressed.
