WHAT I’M WATCHING

Stablecoins: central banks vs banks

In a comment responding to a consultation on EU digital asset regulations, the ECB and the national central banks of the Eurosystem have recommended a change to the official rules on stablecoin reserves. These currently state that issuers keep at least 30% of backing assets in bank deposits; the proportion rises to 60% for large issuers.

This is a requirement that many have pushed back on for years – and, reportedly, the main reason Tether withdrew from Europe rather than apply for the necessary approvals. It’s not just the lack of return on bank deposits, although that is a significant factor. It’s also that bank deposits are not as “safe” as government bonds – banks, after all, are more likely to collapse than a government’s credit.

The central bank objections come from a different angle: systemic risk to banks. Their concern is that stablecoin issuer deposits could replace relatively stable retail deposits, and would be more prone to sharp outflows in a period of market stress. Put differently, stablecoin issuer deposits will be much less “sticky” than those from retail customers.

This is the argument made in a paper published last December by the US Federal Reserve Board of Governors: overall deposit levels may not change as bank customers migrate to stablecoins and reserves are recycled back into bank deposits (contrary to what bank lobbies still claim) – but their composition will change, and that will impact bank stability.
