France tightens rules on stablecoins and wallets

TLDR

France is moving toward stricter oversight of both stablecoins and self-custody crypto wallets, targeting especially non-euro stablecoins and larger private holdings.

1. The Bank of France is pushing EU lawmakers to tighten MiCA rules on non-euro stablecoins used for payments, especially dominant dollar-pegged tokens.
2. Frances National Assembly has advanced a bill to require annual tax reporting of self-custody wallets holding more than 5,000, though final adoption is still uncertain.
3. For crypto users, this points to more compliance friction in France, with risks of limits on dollar stablecoin payments and extra scrutiny for larger self-custody balances.

Deep Dive

1. Tougher Line On Stablecoins

Denis Beau, First Deputy Governor of the Bank of France, has urged the EU to strengthen its Markets in Crypto-Assets (MiCA) regime by further limiting non-euro stablecoins as payment instruments, especially those issued outside Europe and pegged to foreign currencies like the dollar.[](https://cointelegraph.com/news/france-mica-limits-stablecoin-payments)

He argues existing MiCA rules only partially address risks if non-European stablecoins see mass adoption, noting that dollar-pegged coins account for about 98% of the stablecoin market.[](https://cointelegraph.com/news/france-mica-limits-stablecoin-payments) The push fits a broader European concern about monetary sovereignty and reliance on foreign-currency stablecoins for everyday payments.

2. New Reporting Rules For Self-Custody Wallets

Separately, Frances National Assembly has adopted a provision in an anti-fraud bill requiring individuals to report self-hosted wallets (for example, MetaMask, Phantom, hardware wallets) holding more than 5,000 to the tax authority each year.[]()

The measure is controversial. Even the tax agency and government warned that centralizing detailed wallet and identity data would create a hacking risk, and critics say authorities have no realistic way to verify who controls which private wallets.[]() The bill is not fully enacted yet, so the final text could still change.

3. Practical Impact And What To Watch

For now, everyday trading on exchanges is mostly unaffected, but two impact channels are emerging:

1. Payment flows could tilt away from dollar stablecoins in Europe if MiCA is tightened as France wants, affecting merchants and DeFi/payment apps relying on USDT/USDC rails.
2. French residents with significant self-custody balances may need to track portfolio values against the 5,000 threshold and prepare for additional tax reporting if the bill becomes law.

Key things to watch are: the final wording of the French anti-fraud law, EU-level MiCA Phase 2 work on stablecoins, and guidance from French regulators on how strictly they intend to enforce any new wallet reporting rules.

Confidence: high because multiple detailed policy reports from European and French sources describe the same measures and thresholds.

Conclusion

France is trying to reduce dependence on foreign-currency stablecoins and bring larger off-exchange holdings into the tax net, even at the cost of extra friction for compliant users. For crypto participants in or serving France, the edge shifts toward being more selective about which stablecoins are used for EU-facing payments and more disciplined in documenting self-custodied holdings if and when these rules fully come into force.
