UniCredit risk chief warns MiCA stablecoin gap

TLDR

UniCredits risk chief says MiCA leaves Europe exposed in a crisis involving banks that hold stablecoin reserves.

1. Under MiCA, stablecoin issuers must park large reserves in banks, but EU deposit insurance would only protect a tiny fraction in a bank failure.
2. This creates what she calls a "double weakness" where both stablecoin users and banks could be hit in a stress event, unlike the broader US backstops seen in 2023.
3. The EU is already reviewing MiCA and broader stablecoin rules, so these warnings could influence a MiCA 2 update and how future euro stablecoins are designed.

Deep Dive

1. What Carletti Actually Warned About

Elena Carletti, who chairs UniCredits board risk committee, argued that Europe may struggle to contain a crisis that hits both banks and stablecoin issuers under the current MiCA setup.

She highlighted that EU deposit insurance typically covers up to about 100,000 per depositor per bank, while stablecoin issuers may hold billions in reserves at single institutions. In the US, regulators effectively guaranteed all deposits at banks like Silicon Valley Bank and Signature, including reserves backing USDC, which helped restore the peg after it briefly broke.

Carletti warned that taking a similar "protect all deposits" decision in Europe would be much harder, meaning large stablecoin reserve accounts might not be fully protected in a crisis.

2. Why This Gap Matters For Crypto Users

MiCA requires euro stablecoin issuers to hold highly liquid reserves such as bank deposits and government bonds, which ties stablecoin stability directly to bank health. If a reserve bank ran into trouble and the EU could not or would not guarantee all of those deposits, a euro stablecoin could depeg quickly, hurting users and DeFi protocols that treat it as cash-like collateral.

Carletti described this as a "double weakness": banks rely on those deposits as funding, while stablecoin holders rely on them as backing. A bank failure could therefore stress both the traditional banking system and crypto markets at the same time.

For holders of USDT, USDC and future euro stablecoins, the key takeaway is that "MiCA compliant" does not automatically equal "crisis proof."

3. How Europe Might Respond Next

The European Commission has already launched a formal review of MiCA that explicitly targets stablecoin rules, including reserves, liquidity management and redemption rights, with possible "MiCA 2%%CKPROTECTED1%% changes on the table.

At the same time, the ECB has been pushing back against proposals to loosen MiCA constraints on euro stablecoins, citing risks to bank funding and monetary policy if deposits migrate into tokens. In parallel, banking consortia such as Qivalis are working on MiCA compliant euro stablecoins, which will need to navigate these evolving rules and crisis management concerns.

If Carlettis warnings gain traction, the review could expand to crisis tools, such as how large stablecoin reserve deposits would be treated in a bank resolution.

Conclusion

UniCredits warning focuses less on everyday MiCA compliance and more on what happens when things break. By forcing stablecoin reserves into banks without matching crisis protections, Europe risks amplifying shocks across both systems. How MiCAs review and ECB policy evolve from here will shape how safe, scalable and competitive euro stablecoins become against their dollar rivals.
