Digital bank Revolut is suspending access to cryptocurrencies through its platform for U.S. customers citing an uncertain regulatory environment, the platform confirmed to CoinDesk.

U.S. customers will not be able to buy crypto via Revolut starting Sept. 2 but can continue to sell for 30 more days before access to crypto is fully disabled, according to a letter sent by the bank to local clients.

The platform said it took the “difficult decision” with its U.S. banking partner because of an “evolving regulatory environment” in the country. Regulators there, led by the Securities and Exchange Commission, have been cracking down on crypto, targeting exchange platforms like Coinbase (COIN) and Binance, as well as a host of individual tokens including Solana’ SOL and Polygon’ MATIC, alleging violations of federal laws.

“This decision has not been taken lightly, and we understand the disappointment this may cause. This suspension does not affect Revolut users outside of the U.S. in any way, and impacts less than 1% of Revolut’s crypto customers globally. Revolut customers in all other markets can continue to sign up and enjoy using our crypto services,” a spokesperson for Revolut said in an email to CoinDesk.

The London-headquartered Revolut, which has around 25 million customers worldwide, offers a range of crypto services including trading and staking in multiple – mainly European – jurisdictions.

“Revolut is actively pursuing alternative means of providing access to crypto products and we hope to offer crypto in the U.S. again in the future,” a spokesperson for the bank told Decrypt.
