The Treasury just gave the strongest indication yet that the US will get a digital dollar, but an expert says proliferation of CBDCs poses risks to the dollar.

• The US Treasury just made its strongest indication that a central bank digital currency is on the table. 
• "[W]e are engaging in the technological development of a CBDC so that we would be able to move forward rapidly if a CBDC were determined to be in the national interest."
• But an expert says a proliferation of CBDCs could impact the dollar's role on the world stage. 

Lawmakers are still weighing whether to have a central bank digital currency, but the US Department of the Treasury just made its most significant indication that it's on track to become a reality.
