This bill aims to prevent U.S. financial entities from engaging with China's central bank digital currency. It specifically prohibits money services businesses from conducting any transaction, directly or indirectly, that involves a central bank digital currency issued by the People's Republic of China. The legislation achieves this by amending Subchapter II of chapter 53 of title 31, United States Code, adding a new section 5337. This new section defines "money services business" by reference to existing federal regulations and explicitly bans their involvement with the Chinese digital currency. The measure is intended to restrict the flow and use of China's digital currency within the U.S. financial system.
