For example, central bank digital currencies (CBDCs) are coming even faster than many anticipated. The digital yuan is already here; it was introduced in China last February during the Winter Olympics.

Visitors to the Olympics were required to pay for meals, hotels, transportation, etc., using QR codes on their mobile phones that linked to digital yuan accounts. Nine other countries have already launched CBDCs. Europe is not far behind and is testing the digital euro under the auspices of the European Central Bank.

The U.S. was lagging, but is catching up fast.

The Federal Reserve was studying a possible Fed CBDC at a research facility at MIT. Now the idea has moved from the research stage to preliminary development.

Fed Chair Jay Powell said, "A U.S. CBDC could… potentially help maintain the dollar's international standing."
