Citi Launches Custody+ as Real-Time Settlement Reshapes Markets

Citi has launched Custody+, a modular suite of near- and real-time custody services, as its patented Single Event Processing technology completes its United States rollout and pushes more than 80 per cent of the bank's total asset-servicing event volume into real-time processing. The launch, announced on 18 August 2026, repositions one of the world's four largest custodians for an industry moving towards continuous trading, compressed settlement cycles and, later this year, native Bitcoin custody.

For institutional investors, the shift matters because custody has long been the slowest, most manual layer of the trade lifecycle. Citi safeguards assets across more than 100 markets, including 62 proprietary direct-custody markets, and is one of the "big four" custodians that between them hold roughly 180 trillion US dollars in client assets. Any structural change to how those assets are serviced ripples through custodian costs, intermediary spreads and, ultimately, end-investor returns.

What is Citi actually launching?

Custody+ replaces Citi's standardised, one-size custody model with a modular set of components that clients can assemble around their own workflows. The bank frames it as the productised outcome of its Single Event Processing (SEP) technology, first introduced in select European markets and with International Central Securities Depositories in 2025, then extended across North America over the following year.

The measurable gains sit in corporate actions, historically among the most error-prone and manual parts of asset servicing. Citi says the US rollout has cut processing times for voluntary corporate actions by up to 92 per cent, with 96 per cent of US voluntary events now completed in under two hours. These are company-reported figures rather than independently audited results, but they are consistent with earlier disclosures that SEP reduced event creation from hours to minutes and cut payment processing to under five minutes.

The suite groups into three layers. The first, built around speed, covers real-time asset servicing, instant settlement integrated through to final settlement at Central Securities Depositories, and on-demand foreign exchange with automated hedging. The second, focused on intelligence, spans real-time cash and liquidity tools, AI-led tax documentation that Citi says has cut processing times by up to 70 per cent, and an enhanced Market Guide platform available across more than 100 locations. The third addresses diverse operating models through white-label platform access and digital-asset custody.

Why does real-time custody matter now?

The launch lands against a broader structural shift in post-trade infrastructure. The United States moved to a T+1 settlement cycle in 2024, Europe and the United Kingdom are following, and senior figures across the industry now treat round-the-clock settlement as a near-term reality rather than a distant ambition. At a London forum earlier this year, Deutsche Bank's global head of trust and securities services described real-time, 24/7 transfer of value as one of the biggest systemic changes the industry will see in the next couple of years, warning that "perpetual balance sheet velocity" would reshape custodian business models.

That is the competitive pressure Custody+ is built to answer. When markets never close, batch processing and overnight reconciliation cycles become liabilities. Citi's rivals are moving in parallel: the largest custodians have spent the past two years deploying AI across asset servicing and reworking how collateral and data move through their platforms. Citi's own Services business, which spans Treasury and Trade Solutions and Securities Services, invests more than two billion US dollars a year in its platform, and the bank recently expanded its role on BlackRock's Aladdin platform to include full investment book of record and trade management services.

How does digital-asset custody fit in?

The most closely watched element is Citi's plan to go live with digital-asset custody later this year, starting with Bitcoin, built on its common digital-asset architecture so that clients can access traditional and crypto custody within a single framework. The bank first signalled native crypto custody in late 2025, when chief executive Jane Fraser described Citi's ambition to be a one-stop-shop custodian and disclosed a live pilot moving Ether into and out of Citi custody.

The regulatory backdrop has shifted decisively in favour of bank-led custody. The US Securities and Exchange Commission rescinded Staff Accounting Bulletin 121 in January 2025, removing a major accounting barrier that had kept custodied crypto on banks' balance sheets, and the GENIUS Act, enacted in July 2025, set federal standards for stablecoin reserves. Analysts value the digital-asset custody market at around 700 billion US dollars in 2026, projecting expansion to more than two trillion by 2031.

Custody+ also folds in Citi's existing tokenised-deposit capability through Citi Token Services, the bank's private permissioned blockchain platform, which enables near-instantaneous movement of tokenised deposits on a 24/7 basis across select markets. Citi has processed billions of dollars through the platform since its 2024 launch, is live in the US, UK, Singapore and Hong Kong, and in July 2026 joined a Swift pilot of 17 global banks testing round-the-clock cross-border payments using tokenised deposits.

Why This Matters to FinanceX Readers

Custody is quietly becoming a competitive battleground rather than a back-office utility. As settlement cycles compress and tokenised assets move towards continuous trading, the custodians that can service events in real time, across both traditional and digital assets, will set the terms for institutional clients. Citi's Custody+ is a bid to defend and extend its position among the top four global custodians at precisely the moment the economics of the business are being redrawn.

For asset managers, pension funds and treasury teams, the practical questions are whether faster corporate-action processing translates into measurable cost savings, and whether a single-framework approach to traditional and crypto custody delivers the operational simplification it promises.
