Karen Petrou: Why Stablecoin Hegemony Could Cost Too Much
In the battle over stablecoin regulation, defenders of the pending legislation make much of the need for the U.S. to become the dominant global leader. That’s fine, but what if the new stablecoin framework gives the U.S. crypto preeminence at the cost of U.S. bank resilience and macroeconomic growth? That would be a high price to pay, but it’s nonetheless the Faustian bargain lurking in the latest legislation.
As our analyses have made clear, the House and Senate bills address only payment stablecoins – i.e., digital assets used by consumers and companies to settle financial accounts or to purchase goods and services. The idea is to make regulated stablecoins as reliable a medium of exchange as dollars, with the bills’ reserve-asset requirements meant to ensure that one stablecoin dollar always equals one U.S. dollar.
