Coinbase's official notice gives affected customers until 30 October 2026 to withdraw assets they want to retain. The notice lists 14 assets and describes a one-time conversion of remaining balances at the market rate, with another supported asset or currency used where USDC is unsuitable.
The scope is specific: retail customers served by Coinbase Luxembourg S.A. in the EEA. This is not an announcement covering every Coinbase customer worldwide or a direction to all crypto holders to exchange their tokens.
The asset list contains a point to clarify
The notice lists USDT, PAX, PYUSD, GUSD, GYEN, DAI, BUST, UST, RAI, PAXG, MUSD, USD1, USDS and TGBP. It prints "BUST"; that entry should not silently be changed to BUSD. Customers with a potentially relevant balance should check the asset identified in their account and seek clarification where necessary.
Coinbase groups the assets under its stablecoin notice and says they fall into MiCA's e-money-token or asset-referenced-token categories. The list should not be read as 14 identical dollar substitutes. The legal categories and the assets' individual characteristics remain relevant.
Buying, selling and converting the affected assets are restricted, according to Coinbase. Withdrawal is the available route for customers who want to continue holding them outside the platform, where the destination supports the asset and network. The notice's retail EEA scope does not establish equivalent treatment for institutional or non-EEA accounts.
What customers will see during conversion
Coinbase says an affected balance may temporarily display as zero during processing. A conversion entry should then appear in transaction history and the resulting balance should be credited. The conversion uses the market rate at execution, not a promised face value.
The page's opening says balances remaining after 30 October will be converted, while its conversion section says conversion takes place on 30 October. It does not specify a precise cutoff time or time zone. Customers should not assume the wording promises access until the final minute of that date.
The notice also does not specify a conversion fee or detailed pricing methodology. That leaves no basis for describing the operation as fee-free. Coinbase warns that conversion may have tax consequences in some jurisdictions; holders should retain the transaction record and check their own obligations.
Assets sent after 30 October will not be credited, traded, transferred or included in the automatic conversion, Coinbase says. Recovery may be possible only through its unsupported-asset process where technically available. It is not guaranteed. Future support for an asset would not reverse an already completed conversion.
MiCA has several different dates
Coinbase attributes the restrictions to MiCA and refers to a transition ending on 1 July 2026. The underlying legal timetable needs a distinction: Article 143 sets that outer transition date for qualifying crypto-asset service providers. It is not a universal starting date for stablecoin issuer requirements.
Under Article 149, MiCA's asset-referenced-token and e-money-token titles applied from 30 June 2024, while the regulation generally applied from 30 December 2024.
ESMA's 8 October 2026 supervisory opinion says authorised providers should cease services involving non-compliant stablecoins for EU clients. It calls for remaining pre-existing exposures to be addressed as soon as possible and no later than three months after publication. Coinbase's 30 October date is its platform timetable, not a universal EU conversion date.
USDC's designation changes who supervises the issuer
In a separate 14 October announcement, the EBA classified USDC issued by Circle Internet Financial Europe SAS as the EU's first significant e-money token. It was the first among 45 notified EMTs to receive that classification.
From 12 November 2026, the EBA takes direct responsibilities for own funds, reserves, liquidity, recovery and redemption plans. France's ACPR retains areas including governance, qualifying holdings, management suitability, outsourcing and conflicts of interest. The arrangement is dual supervision, not the disappearance of the French authority.
That designation does not itself convert anyone's balance, guarantee a market price or make every network version available on every platform. For affected Coinbase holders, the immediate questions remain operational: which balance is covered, whether they want to withdraw it, and what their account notice says about execution. The supervisory change is important context, but it is a separate decision.
