When Standard Chartered (STAN) said it would offer institutional clients direct access to minting and redeeming Circle Internet's (CRCL) USDC this week, it wasn't simply adding another digital asset service.

Rather, it was joining a growing list of global financial institutions building product offerings around stablecoins, the fiat-pegged tokens that were once retail investors' refuge from crypto-market volatility and are increasingly becoming part of the plumbing of financial institutions worldwide. Chainalysis estimates stablecoin settlement volumes could reach a quadrillion dollars a year by 2030.

Standard Chartered’s announcement came just days after BNY, the world's largest custody bank, expanded its support for USDC by allowing institutional clients to custody, mint and redeem the stablecoin using its infrastructure rather than building their own. Both Standard Chartered and BNY, which has $59 trillion in assets under management, are considered global systemically important banks by the Bank for International Settlements' Basel Committee.

Their decisions reflect a pattern among some lenders toward using established stablecoin networks rather than creating their own. The moves also suggest the conversation inside banking has shifted. The question is no longer whether stablecoins belong in finance, but how banks fit into the networks forming around them.
