Stablecoins vs. bank deposits
CoinGecko flagged that roughly $6.6 trillion in bank deposits could shift on‑chain if yields keep diverging in favor of stablecoins, a figure cited in social discussions this week (x.com). U.S. bankers are already warning that stablecoin policy choices could drain deposits from traditional banks, a concern echoed in recent posts (x.com).
Stablecoins are colliding with bank deposits as lawmakers and regulators decide whether digital dollars can keep paying yields that many checking and savings accounts do not. (coingecko.com) A stablecoin is a digital token designed to stay at $1 and move on blockchain networks like cash on internet rails. Under the GENIUS Act, issuers must hold at least one dollar of reserves for every dollar of coins they issue, using assets such as cash, insured-bank deposits, short-dated Treasury bills and government money market funds. (congress.gov) CoinGecko said stablecoins now total about $310 billion, while Brian Moynihan of Bank of America warned in January 2026 that as much as $6 trillion of deposits could move if platforms are allowed to pay interest on stablecoins. CoinGecko’s explainer, published in April 2026, put the higher banking-industry estimate at roughly $6.6 trillion. (coingecko.com) The fight has centered on yield. CoinGecko said standard savings accounts at Chase and Bank of America were paying about 0.01 percent annual percentage yield in March 2026, while Coinbase and Kraken were offering roughly 3.5 percent to 5 percent rewards on United States dollar coin, or USDC. (coingecko.com) Congress already drew one line. A Congressional Research Service summary of the GENIUS Act says issuers are prohibited from paying interest to stablecoin holders, and the law was enacted on July 18, 2025. (congress.gov, congress.gov) The unresolved question is whether exchanges can keep passing through yield anyway. A March 2026 Congressional Research Service brief said GENIUS does not explicitly stop exchanges from paying rewards on stablecoins they custody for retail users, even when the issuer is supplying the economics behind those payments. (congress.gov) Bankers have pushed Congress to shut that gap. On December 18, 2025, the American Bankers Association and 52 state bankers associations said exchanges were exploiting a loophole and warned that the practice could “disintermediat[e] core banking activity, including deposit taking and lending.” (aba.com) Regulators are now writing the rulebook that could decide how much room stablecoins have to compete. The Office of the Comptroller of the Currency issued a proposed rule on February 25, 2026, to implement the GENIUS Act for banks, subsidiaries, approved nonbanks and certain foreign issuers under its jurisdiction. (occ.treas.gov) Banks are making the case from a funding angle. CoinGecko cited an American Bankers Association estimate that a large shift from deposits to stablecoins could cut bank lending capacity by up to $1.26 trillion, a claim the banking lobby ties to mortgages, student loans and small-business credit. (coingecko.com) The banking system still sits on a far larger base than crypto. The Federal Deposit Insurance Corporation’s Quarterly Banking Profile, updated February 24, 2026, said it tracks loan and deposit activity across Federal Deposit Insurance Corporation-insured institutions, while CoinGecko’s stablecoin category showed a market cap of about $312 billion in early April 2026. (fdic.gov, coingecko.com) What happens next is less about whether stablecoins exist than about whether they act like payment tools or high-yield deposit substitutes. That answer now sits with the agencies writing GENIUS Act rules and with Congress if it decides the yield ban needs to be tightened. (occ.treas.gov, congress.gov)
