ECB Official Claims Stablecoins Threaten Bank Deposits, Backs Digital Euro

European Central Bank (ECB) board member Piero Cipollone recently warned that stablecoins — cryptocurrencies pegged to fiat like the US dollar or euro — could drain bank deposits and undermine monetary policy. His solution: a digital euro. This has reignited a long-running debate over the role of central bank digital currencies (CBDCs) versus private stablecoins. Here's a balanced look at the arguments on both sides.

Cipollone's Three Threats

Cipollone outlined three main risks from the rise of digital payments, particularly stablecoins and other private digital money: first, the potential disintermediation of banks if deposits shift to stablecoins; second, a loss of monetary policy transmission if money creation escapes central bank control; and third, risks to financial stability from runs on stablecoin reserves. He argued that a digital euro would preserve the role of central bank money in the digital age, offering a safe, state-backed alternative.

What Supporters of the Digital Euro Say

Supporters, including ECB officials and some lawmakers, argue that a digital euro is necessary to maintain monetary sovereignty. They point out that if stablecoins become widely used for everyday payments, the ECB would lose its ability to set interest rates effectively, as money would circulate outside the banking system. They also claim a digital euro would offer better privacy and security than private stablecoins, as the ECB would not monetize user data. Additionally, they say it could foster innovation in European payments and reduce reliance on US-based payment systems.

What Critics and Regulators Say

Critics, including some commercial banks and privacy advocates, raise concerns that the digital euro could itself cause bank disintermediation. If households and businesses can hold digital euro directly with the ECB, they might move deposits out of banks, reducing banks' ability to lend. Critics also worry about state surveillance: even with privacy measures, the ECB could theoretically monitor transactions. Others argue that stablecoins are not the real threat because they remain small relative to bank deposits, and that regulatory frameworks like MiCA already address stablecoin risks. Some regulators question whether the digital euro is needed at all, given that existing payment systems already work well for most Europeans.

What to Watch Next

The debate is far from settled. Key developments to monitor include: the European Commission's legislative proposal for a digital euro, expected in 2024; the results of the ECB's ongoing pilot tests; and the implementation of the Markets in Crypto-Assets (MiCA) regulation, which sets rules for stablecoins. Also watch for reactions from major banks and consumer advocacy groups. Whether or not a digital euro launches, the discussion reveals a fundamental tension between public and private digital money — one that will shape the future of finance.
