1 in 71 US dollars are now on-chain. Digital Dollar Dominance is a public benchmark tracking what share of the total US money supply exists as stablecoins, updated live. The current ratio is calculated as total stablecoin supply divided by US M2 and has been rising steadily since 2019. That supply expands and contracts through issuance and redemption across multiple chains, concentrated among a small number of issuers. Stablecoin supply already exceeds the entire domestic money supply of 177 countries, with Taiwan within reach.
