Will Interest Payments Make Stablecoins More Interesting?

Why It Matters

If interest bans hold, banks’ tokenized deposit projects (notably JPMorgan’s permissioned ERC‑20 pilot) could gain, but otherwise large, automated swings between stablecoins and yield accounts pose liquidity and systemic risks as crypto grows.

Summary

Global stablecoin rules are converging on requirements for high‑quality reserves, audits and explicit bans on issuers paying interest, but those prohibitions may be porous in practice as exchanges already market “rewards” and users can route coins into DeFi yield instruments. At current nominal rates of roughly 3–4% the economics already favor short‑term automated moves (earning about $3.07 on $1,000 over 28 days), and on‑chain capacity—roughly 400,000 complex DeFi transactions per day on Ethereum—means these flows could scale. If interest bans hold, banks’ tokenized deposit projects (notably JPMorgan’s permissioned ERC‑20 pilot) could gain, but otherwise large, automated swings between stablecoins and yield accounts pose liquidity and systemic risks as crypto grows.
