I'm still convinced the only reason a stablecoin can do international payments faster/better than Zelle itself is because of regulation.
Early Warning Services, the network operator of Zelle®, today announced a new initiative to enable Zelle to deliver faster and more reliable cross-border money movement.
"Our goal is to bring the trust, speed and convenience of Zelle to consumers' international money movement needs. We're investing where consumer need, bank capability and global opportunity intersect. With improved regulatory clarity in the U.S., we can focus on what we do best: driving innovation to market."
Supported by the owner banks of Early Warning Services, the initiative is designed to expand on the success of Zelle in U.S. payments while addressing one of the most persistent challenges in global money movement: sending money safely and conveniently across borders. The offering will be made available to all Zelle Network financial institutions with the intention to provide equal terms to all participants.

The statement did not specify which stablecoins Zelle would use. Early Warning Services is owned by major American banks Bank of America, Capital One, JPMorgan Chase, PNC Bank, Truist, U.S. Bank, and Wells Fargo.
