The Mobilisation Gap: Near 24/7 Settlement Meets an Office-Hours Collateral Perimeter

Central banks are admitting tokenised assets to the eligible collateral pool only where they re-use existing depositories, while pushing settlement towards continuous operation. The gap between when an obligation arises and when collateral can legally move lands as an intraday liquidity cost on bank treasuries from 2027 to 2031.

The consensus on tokenisation has settled into a familiar shape: faster settlement, cheaper post-trade, and a contest between stablecoins and tokenised deposits over which private money wins. The decisions regulators actually took this year were narrower, and they were about collateral. The Eurosystem and the Bank of England have each admitted tokenisation on one condition: that it re-uses the depositories, clearing houses and central bank accounts already in place. Separately, and on a different clock, settlement hours are being extended towards continuous operation. Obligations will therefore arise at hours when eligible collateral cannot legally be moved. That gap, not settlement speed, is what reaches bank treasuries first.

Signal Identification

A regulatory pivot with an operational tail. The eligibility decision is settled and public; its consequence is not. A widening window opens in which margin and payment obligations arise while the legal mobilisation of collateral stays bound to depository opening hours. The signal binds when extended settlement hours arrive, not when tokenised issuance reaches scale.

Time horizon: 3–6 years (eligibility live March 2026; CHAPS opens 01:30 September 2027; weekend settlement 2029 at the earliest; 22-hour weekdays 2031 at the earliest)

What's Changing

Every eligibility decision this year carries the same condition. Since 30 March 2026 the Eurosystem has accepted marketable assets issued in central securities depositories using distributed ledger services, provided they settle in TARGET2-Securities, so the mobilisation process is the same as for any other marketable asset it accepts (European Central Bank, 07/05/2026). The Bank of England adopted the same principle, enabling tokenised equivalents of already eligible assets to serve as collateral at central counterparties and in its own operations (Bank of England, 18/05/2026). Tokenised form is admitted; the perimeter is not redrawn.

The pool inside that perimeter is thin: euro-denominated debt with digital exposure stood at around €2 billion at the end of 2025 (European Central Bank, 07/05/2026), against distributed-ledger repo turnover the sell side puts at $384bn a day (AFME, 03/07/2026), almost all of it outside the eligible set. The direction is international: innovation delivers when anchored in sound arrangements and strong supervision (Bank for International Settlements, 23/06/2026).

The settlement clock moves separately. CHAPS opens at 01:30 from September 2027; the Bank proposes weekend and bank holiday settlement no earlier than 2029, then 22-hour weekdays no earlier than 2031, with consultation responses closing today (Bank of England, 18/05/2026). That paper concedes wider consequences for prudential liquidity rules, including how intraday requirements are set. At the Bank's RTGS CHAPS Industry Forum, liquidity management was noted and deferred (Bank of England, 15/06/2026).

Milestones as stated by the European Central Bank (07/05/2026) and the Bank of England (18/05/2026). The undated band records the Bank's own statement that the prudential treatment will be communicated in due course.

Disruption Pathway

The pathway runs in three stages. Through 2026 and 2027 the eligible pool stays small and capital treatment, not time, is the binding constraint. From September 2027 the first divergence opens, as sterling settlement runs from 01:30 while depositories and triparty agents keep conventional hours. From 2029 weekend settlement removes the longest window in which nothing settles, and with it the assumption behind every intraday liquidity model: that obligations pause when the collateral infrastructure does. AFME reaches the same juncture from the other side, arguing a synchronisation capability targeted for 2028 may be too slow if tokenised assets scale earlier (AFME, 03/07/2026).

Stress concentrates at three points. Bank treasuries carry the buffer bridging an obligation arising at 02:00 on a Sunday against collateral that cannot be substituted until Monday. Clearing members carry margin calls timed by the venue, not the depository. Custodians and triparty agents carry the cost of staffing hours their revenue model never assumed. Two adaptations follow. Operationally, prefunding rises: atomic settlement reduces principal risk but raises intraday liquidity demand, because settling gross in real time ties up more cash than deferred netting (OMFIF, 06/08/2026). Prudentially, supervisors must restate intraday liquidity requirements for a week with no natural close. Firms treating this as an operations problem will meet it as a funding cost.

Why This Matters Now

Bank treasurers, chief risk officers and clearing-member boards are being asked to invest in tokenisation on a payments business case while the measurable effect arrives through collateral and liquidity. What needs revision is the intraday liquidity model: most are calibrated on a five-day, fixed-close week, and every published milestone erodes that assumption without replacing the rules sitting on top of it. Boards should be asking what their buffer looks like on a Sunday in 2029, which collateral can be mobilised outside depository hours, and whether the answer is a technology build, a larger buffer, or a smaller book. Those answers are cheap now and expensive once the operating model has been rebuilt around the old week.

Decision-action posture for this signal: Prepare — the eligibility rules are already live and the settlement timetable is published, but the prudential treatment that determines the cost is not, so the sensible commitment is scenario work and collateral-inventory mapping against a named trigger: the Bank's statement on intraday liquidity requirements.

Counter-Argument

The strongest objection is that this reads a sequencing artefact as a durable exposure. AFME's position is that tokenised collateral cuts liquidity need rather than raising it, calling fungible tokenised securities used as collateral across CCPs, uncleared derivatives and central bank operations the clearest and most actionable commercial opportunity available (AFME, 03/07/2026). On that reading commercial pressure closes the window as depositories follow the settlement clock. The same response argues the binding constraint is capital, not time: Basel classification can push low-risk exposures into Group 2b at a 1,250% risk weight, stalling adoption before opening hours matter.

That objection is right about the destination and wrong about the interval. Depositories will extend hours on their own investment cycles, and the Bank places no date on the matching prudential rules. An exposure resolving in 2032 still has to be funded by a 2027 balance sheet. AFME concedes as much in passing, listing pre-positioning liquidity to meet atomic settlement demand among the costs to be weighed.

Implications

This catalyses durable change, but not the change the tokenisation debate has been arguing about. By requiring eligible tokenised assets to be reachable through existing depositories, the Eurosystem ensured the mobilisation process is the same as for any other marketable asset it accepts (European Central Bank, 07/05/2026), entrenching incumbent market infrastructure at the moment it was expected to be disintermediated. The inflection window runs from September 2027 to 2031. Depositories and clearing houses that extend hours early capture the collateral flow; banks with concentrated, hard-to-mobilise pools pay the difference in buffers. None of that depends on tokenised issuance reaching scale.
