Citi will custody bitcoin on its equities platform, and plans to hold the coins itself

Citi said Tuesday that Custody+, its new suite of near or real-time custody and settlement tools, will add digital asset custody later this year, beginning with bitcoin ^[1][2]. Clients will reach traditional securities and crypto through the same framework ^[3], which matters less as a feature than as the removal of the last operational excuse an allocator had for staying out: a separate counterparty, a separate onboarding file, a separate reconciliation process and a separate legal review.

The sentence that should concern crypto-native custodians predates Tuesday's release. Biswarup Chatterjee, Citi's global head of partnerships and innovation, said in October that the bank wanted to offer a credible custody solution with Citi holding native tokens itself rather than routing them through outside exchanges ^[5]. Set that against U.S. Bancorp, which relaunched institutional bitcoin custody in September 2025 with NYDIG as sub-custodian, joining BNY Mellon, Fidelity, Coinbase and Anchorage Digital in the business, according to Cryptopolitan ^[11]. Sub-custody has been the crypto-native annuity: the bank keeps the client, the specialist keeps the keys and a share of the fee. Citi is proposing to keep both sides.

The permission structure is already dated. The OCC told institutions in May 2025 they could offer crypto custody, and the GENIUS Act eased bank handling of stablecoins and other blockchain assets ^[9]. The SEC repealed Staff Accounting Bulletin 121, the guidance that made holding client crypto capital-intensive, and replaced it with SAB 122 ^[10]. What was left after that was plumbing, and plumbing is what Citi is selling.

On scale, Citi's custody business supports clients in more than 100 markets, 62 of them proprietary ^[17], which leaves roughly 38 reached some other way ^[20]. That hybrid is worth remembering, because Chatterjee said some services would be built in-house while others might rely on a third-party, lightweight, nimble solution ^[8]. Chris Cox, head of investor services, says Citi's Services business invests more than $2 billion annually in platform strategy ^[16]. Citi also says more than 80% of its asset-servicing event volume is now processed in real time ^[18], which is another way of saying close to a fifth is not ^[19]. Amit Agarwal, head of custody at Citi Investor Services, called Custody+ the product of a multi-year commitment to infrastructure that matches the speed of client strategies ^[25], and the bank frames it as a move from standardized custody to a modular set of solutions ^[26].

The dates do not fully agree. Cryptopolitan puts the first disclosure of native crypto custody in November 2025 and the development work at close to three years ^[6]; Decrypt dates the reveal to October, with a 2026 launch ^[7]. Either way, "later this year" is now the operative window ^[2], and none of the disclosures reviewed here put a number on pricing.

Competitors are splitting. Deutsche Bank has said it will launch custody in 2026 with help from Bitpanda ^[12], Morgan Stanley applied in February for a national trust bank charter for an entity that would offer crypto custody ^[14], and Jamie Dimon has said JPMorgan will let clients buy crypto but will not hold it for them ^[13].

Three things to watch. Whether bitcoin gets a second token, since it is the only one named so far ^[4]. Whether Citi's tokenized-deposit work becomes the settlement leg for this custody: Citi Token Services already moves tokenized deposits nearly instantly, 24 hours a day, in select markets ^[21], the bank worked with ICE in January and joined a Swift pilot in July ^[22], and The Clearing House network it supports plans a launch in the first half of 2027 ^[23]. And whether the NYSE platform Citi and BNY are working on for tokenized stocks and ETFs lands on the same rails ^[15]. Bitcoin was around $64,660 when the news broke ^[24], which tells you the announcement was not built for this month's tape.
