A new research paper published by the Bank for International Settlements (BIS) explores the competitive relationship between traditional banking and the stablecoin market. The study posits that the growth of stablecoins, which are digital assets pegged to fiat currencies, is significantly influenced by the interest rates offered by commercial banks on standard savings accounts.

According to the BIS, when banks provide higher interest rates to savers, the incentive for users to hold stablecoins—which often do not pay interest or pay lower yields—diminishes. The report suggests that stablecoins have gained popularity partly because they offer a digital alternative to traditional banking during periods when bank deposit rates are low or stagnant. By increasing the returns on traditional deposits, banks could theoretically reclaim some of the market share currently held by stablecoin issuers.

This analysis highlights a structural tension in the financial sector where digital assets compete directly with legacy banking products for liquidity. While stablecoins offer benefits such as 24/7 settlement and integration with decentralized finance (DeFi) protocols, the BIS paper emphasizes that the 'opportunity cost' of holding these assets—measured against the interest one could earn in a bank—remains a primary driver of user behavior. The report does not explicitly call for regulatory intervention but rather frames the shift as a market-driven dynamic that banks can influence through their own interest rate policies.
