CPI is a price index. If CPI rises, it means that prices rise, which means that the purchasing power of the same amount of dollars declines, which means that the dollar depreciates in disguise.

The dollar is the world currency. If the CPI in the United States is high, then the dollar will inevitably flow out of the United States in large quantities, and the American economy will slow down and the dollar will be weak.

In recent years 10, the CPI of the United States has been very low, which ensures the sustained and slow development of the American economy and has a stable effect on the world economy. The United States is the largest economy in the world, and the strength of the dollar is beneficial to many countries, because many countries have kept a certain amount of dollars as reserves, and the weak dollar has caused large foreign exchange losses in these countries.
