Citigroup Explores Stablecoin Custody and Crypto ETF Services Amid Regulatory Shift

Citigroup (C.N) is evaluating the provision of stablecoin custody and related services, signaling growing interest from traditional financial institutions in the cryptocurrency sector, a senior executive told Reuters. The move comes as recent U.S. legislation paves the way for stablecoins—digital tokens pegged to fiat currencies like the U.S. dollar—to be used more broadly for payments, settlements, and other financial services.

Under the new law, stablecoin issuers must hold safe assets, such as U.S. Treasuries or cash, to back their digital coins. This creates potential opportunities for custody banks to provide safekeeping and administration. “Providing custody services for those high-quality assets backing stablecoins is the first option we are looking at,” said Biswarup Chatterjee, global head of partnerships and innovation for Citigroup’s services division. Citi’s services business, covering treasury, cash management, payments, and corporate services, remains a central unit amid ongoing restructuring.

Currently, roughly $250 billion in stablecoins have been issued, primarily for settling cryptocurrency trades, according to a McKinsey study. Citigroup is also considering custody services for digital assets linked to crypto investment products, such as bitcoin ETFs. For instance, BlackRock’s iShares Bitcoin Trust—the largest bitcoin ETF—has around $90 billion in market capitalization, requiring custody of an equivalent amount of digital currency. Coinbase currently dominates this business, serving as custodian for more than 80% of crypto ETF issuers.

In addition to custody, Citigroup is exploring the use of stablecoins to accelerate payments, which in traditional banking can take several days. Citi already offers “tokenized” U.S. dollar transfers via blockchain across New York, London, and Hong Kong 24/7 and is developing services that allow clients to send stablecoins or convert them to dollars for instant payments.

The regulatory environment under the Trump administration has become more accommodating to crypto expansion, though Citi and other firms must still adhere to anti-money laundering, currency control, and other compliance requirements. Chatterjee emphasized that crypto custody must ensure assets are legitimately sourced and maintain robust cybersecurity and operational safeguards. The issuance of a Citi-backed stablecoin is also under consideration.
