Argentine presidential candidates Javier Milei has vowed to dollarize Argentina’s economy and close down the central bank.

Central banks have a couple of tools they can use to push back, including interest rate hikes and selling U.S. dollars..

A year ago, U.S. exporters were complaining that the dollar was too strong. Not anymore.

Why some countries are moving away from U.S. bucks.

The dollar has lost value against major currencies since last summer. This means U.S. products are cheaper abroad, but importing is more costly.

The currency’s dip could be due to the prospect of a weakened U.S. economy in 2023.

The greenback’s strength has made it tough for U.S. businesses to compete overseas.

Countries that import commodities priced in U.S. dollars, like oil, are paying a lot more. So are nations that have dollar-denominated loans.

The dollar index hit a 20-year high in European trading, the result of the Fed’s rate hikes and the relative strength of the U.S. economy.

But it’s great for Americans who want to buy imports.
