Coinbase to Convert EEA Users' USDT and 13 Other Non-MiCA Stablecoins on 30 October

Remaining retail balances will become USDC where suitable, or another supported asset, at the market rate. Customers who want to keep the tokens must withdraw them first. ESMA has told platforms to deal with non-compliant stablecoin holdings within three months.

Coinbase will convert the remaining balances that retail customers in the European Economic Area hold in 14 stablecoins it can no longer support under the EU's Markets in Crypto-Assets Regulation (MiCA), on 30 October 2026, according to its help centre. The list includes USDT, PYUSD, DAI and USD1. Coinbase says balances will be converted at the market rate at the time into USDC where suitable, or into another supported asset or currency where not. Customers who want to keep the original tokens have until 30 October to withdraw them to an external wallet. Buying, selling and converting the affected tokens on Coinbase is already restricted.

The full list on the help page is USDT, PAX, PYUSD, GUSD, GYEN, DAI, BUST, UST, RAI, PAXG, MUSD, USD1, USDS and TGBP. Coinbase says it can no longer support stablecoins whose issuers are not authorised under MiCA, after the transitional period for issuers ended on 1 July 2026. Coinbase serves EEA customers through Coinbase Luxembourg S.A., which the help page identifies as a crypto-asset service provider authorised by Luxembourg's CSSF.

What happens on 30 October

Coinbase describes the process as a one-time conversion of the balance held on that day. The balance may briefly show as zero before a conversion entry appears in the transaction history.

Deposits of any of the 14 tokens sent to a Coinbase account after 30 October will not be credited and cannot be traded or converted, the company says. They may only be returned through its unsupported-asset recovery process, which does not work for every asset or network. Coinbase also warns that converting one crypto asset into another may be a taxable event in some countries. If a token later becomes MiCA-compliant, it will reassess support, but that will not reverse a completed conversion.

Why platforms are moving now

The deadline follows the European Securities and Markets Authority (ESMA)'s opinion of 8 October 2026 on services related to unauthorised asset-referenced and e-money tokens. ESMA set out its expectation that crypto-asset service providers stop offering services for tokens that are not MiCA-compliant and deal with existing client holdings within three months. The opinion does not name individual tokens.

Coinbase is moving well inside that window. By converting holdings rather than leaving them stranded, it also avoids running a long tail of restricted balances that clients can hold but not trade.

The commercial effect

The conversion turns a compliance step into a distribution event for compliant tokens. For customers who do not withdraw, balances in USDT, PYUSD, USD1, DAI, USDS and the other listed tokens will end up in USDC where Coinbase considers it suitable. The help page does not say how many customers or what value is affected.

For issuers outside the EU regime, the practical cost is losing a passive retail holder base on a major regulated venue. Their tokens can still circulate on-chain and through unregulated channels. But EEA retail users who want them must now hold them in self-custody rather than with an authorised platform. That is the separation ESMA's opinion is pushing CASPs to enforce.
