BIS Chief: Stablecoins "Not Credible" for Payments at Scale

Date: August 28

BIS General Manager Pablo Hernández de Cos stated that stablecoins do not credibly function as a means of payment at scale, arguing that tokenized bank deposits offer a stronger alternative. The BIS-linked Financial Stability Institute (FSI) simultaneously published a comparative study of stablecoin regulations across the US, EU, UK, Hong Kong and Singapore, finding substantial differences in permissible activities for non-bank issuers. De Cos also acknowledged that stablecoins could lower government borrowing costs but warned that deposit outflows to stablecoins could raise bank funding costs for households and businesses.

ECB's Schnabel: Central Banks Must Go On-Chain; Pontes Nears September Launch

At Jackson Hole, ECB Executive Board member Isabel Schnabel delivered her most direct statement on tokenization: central bank money on blockchain is no longer optional. She warned that if public money stays off-chain while financial assets move on-chain, dollar stablecoins would become the default cash leg, threatening European monetary sovereignty. The Eurosystem's Pontes bridge infrastructure is set to pilot in September 2026, featuring an ECB-operated DLT platform for settling tokenized transactions in central-bank money, with smart contracts and 24/7 operations on the roadmap. Schnabel framed stablecoins as complements — useful for edge payments but unable to expand liquidity elastically in a crisis.

MiCA-compliant stablecoins may face more direct competition from central bank digital currency, as the ECB and BIS align on a three-layer stack: tokenized reserves, then tokenized deposits, then regulated stablecoins for edge use cases.
