Collateral mobility and the custody question

Standard Chartered's Future of Trade series closed on 24 July 2026 with Kevin Chang, the bank's Head of Trade and Working Capital for Hong Kong and Greater China North Asia and Group Head of Trade Digital Assets, and trade product director Emily Chan mapping tokenisation onto trade in 3 layers:

• Tokenised trade instruments
• Tokenised trade finance assets
• Tokenised money

The phrase that matters is theirs: collateral mobility as the "killer use case." Their worked example is the bank's own collateral mirroring programme, which lets clients post tokenised money market funds as off-exchange collateral, held by a regulated third party rather than the exchange.

The diagnosis is right, but the piece undersells the reason it wins. The framing is mobility: trapped liquidity reaching where it's needed across borders. True, and secondary. The sharper economics are yield. Pre-funding margin with cash earns nothing on the pledge; posting a tokenised money market fund instead keeps the money-market yield running for the life of the collateralisation. Across a margin financing or repo book, cash drag on pre-funding is a standing cost line, and the opportunity cost of posting collateral drops materially once it stops applying. That changes the capital-allocation calculus for whoever runs that book. Mobility gets the collateral there; yield is why the chief financial officer signs off.

The pattern's already visible in Asia, with an important caveat. DBS, Franklin Templeton and Ripple signed a memorandum of understanding in September 2025 to enable sgBENJI, the Singapore token of Franklin's onchain US dollar money market fund, as collateral for repo-based borrowing, with DBS acting as collateral custodian. As of mid-2026 that facility's still described in intent tense rather than confirmed live, so it belongs in the pipeline column, not the production column. The design, though, is the tell: the bank didn't position itself as issuer or platform. It positioned itself as the custodian in the middle.

Which is the question the trade piece leaves open: whose custodial infrastructure holds the pledge, and who recognises it. Off-exchange collateral means a regulated third party stands between the counterparties. A pledge over a tokenised fund perfected under Singapore law and held with a Singapore custodian is only as mobile as the willingness of a Hong Kong or London counterparty's risk function to take it at full value. Legal finality, insolvency netting and haircut treatment all run through the custodian's jurisdiction and the recognition agreements around it. Cross-border collateral mobility without cross-border custodial recognition is the trapped-liquidity problem again, at higher speed and with better marketing.

The recognition layer is likely to consolidate early. Triparty agents and international central securities depositories solved the equivalent problem for conventional collateral decades ago, and the tokenised version will either plug into that plumbing or get rebuilt under a handful of bank custodians who move first. The banks placing themselves in the middle now, Standard Chartered with mirroring, DBS with custody of the sgBENJI pledge, are bidding for that seat rather than for issuance economics.

For any margin financing or repo book, 2 questions are worth asking this quarter:

• What does the cash-drag line on pre-funded collateral actually cost, priced against a tokenised MMF alternative?
• For any tokenised collateral a counterparty proposes, in which jurisdictions is the pledge enforceable, and who nets in an insolvency? That's a question for the custodian to answer in writing, not the platform's marketing.

Value in this use case settles not with whoever mints the token but with whoever's custody network the pledge is recognised across. Recognition, not issuance, is the scarce asset, and the institutions that get that are already sitting down in the middle of the table.
