Wall Street giant Citigroup is weighing plans to offer cryptocurrency custody and payment services, aiming to capitalize on a market bolstered by Trump-era regulatory approvals and pro-industry legislation.

Biswarup Chatterjee, a Citigroup executive, told Reuters that the bank’s initial focus would likely be custody services for “high-quality assets backing stablecoins.”

Chatterjee works within Citigroup’s services division, which manages treasury, payments, cash management and other enterprise solutions for large corporations.

The bank is also exploring custody offerings for crypto-linked exchange-traded products, which could include Bitcoin (BTC) and Ether (ETH) exchange-traded funds (ETFs).

“There needs to be custody of the equivalent amount of digital currency to support these ETFs,” Chatterjee said. 

Bitcoin ETFs have surged in popularity since their debut in early 2024. According to Bitbo, the 12 US spot Bitcoin ETF issuers now hold nearly 1.3 million BTC — about 6.2% of the total circulating supply.

BlackRock’s iShares Bitcoin Trust (IBIT) is the largest, with an estimated market value of around $88 billion.

After a slow start, Ether ETFs have seen a surge of inflows, with BlackRock’s Ethereum fund becoming the third-fastest in history to reach $10 billion in assets.

Custody, payments wouldn’t be Citi’s first move into crypto

Citigroup’s exploration of custody and payment services wouldn’t mark its first foray into the cryptocurrency market.

Earlier this year, the bank partnered with Switzerland’s SIX Digital Exchange to leverage blockchain technology to improve private markets through tokenization. 

Citi has been eyeing tokenization since at least 2023, when it described the technology as the next “killer use case” in crypto — estimating it could reach a $5 trillion market valuation by 2030.

Citi was also reportedly among several Wall Street giants, including JPMorgan, Wells Fargo and Bank of America, exploring the possibility of issuing a joint stablecoin.

A recent report by Ripple, CB Insights and the UK Centre for Blockchain Technologies ranked Citigroup among the most active institutional investors in blockchain companies, with 18 deals between 2020 and 2024.

Traditional financial institutions have been buoyed by Trump-era efforts to provide regulatory clarity for the crypto sector — initiatives that have extended to the US Securities and Exchange Commission and the recent passage of the US GENIUS Act, a key stablecoin law.

In July, the House of Representatives passed the CLARITY market structure bill, the Anti-CBDC Surveillance State Act and the GENIUS Act.
