Global banks and market infrastructures are testing how tokenized gilts could reshape cross-border collateral markets on the Canton Network, an institutional-grade blockchain.
A consortium of major financial firms has executed the first cross-border, intraday repurchase agreement using tokenized U.K. government bonds on the Canton Network, an enterprise-focused blockchain designed for financial institutions.
The landmark trade involved a cross-border intraday repo in which digital versions of U.K. gilts were mobilized as collateral. According to a release shared on CoinDesk, this is the first time the roughly $2 trillion gilt market has been used in such a structure across jurisdictions.
Moreover, the transaction featured the first cross-currency leg in this context, with tokenized gilts exchanged against tokenized deposits denominated in a non-sterling currency. Smart contracts embedded both interest payments and detailed risk terms directly into the lifecycle of the trade.
The deal was backed by a roster of traditional and digital finance players, including LSEG, Euroclear, DTCC, Tradeweb, Citadel Securities and Societe Generale. Digital asset specialists such as Archax and Cumberland DRW also took part, reflecting growing institutional interest in on-chain collateral flows.
Furthermore, TreasurySpring coded the economic terms directly into smart contracts, embedding interest calculations and risk parameters at the protocol level. By placing both the cash leg and the bond collateral on a shared ledger, the participants aim to enable atomic, intraday movements of assets without relying on traditional batch processes.
In a classic repo, one party sells a security with an agreement to repurchase it later, often within the same day. Banks and trading firms rely on these agreements to raise short-term funding and to manage daily liquidity needs efficiently.
The experiment is central to Canton’s ambition to unlock more of the roughly $300 trillion pool of global high-quality liquid assets as usable collateral. Kelly Matheison, chief business development officer at Digital Asset, said the aim is to transform how government bonds and similar instruments are deployed across borders.
Digital Asset, the main development firm behind Canton, raised capital in 2023 from financial heavyweights including Goldman Sachs, DRW, Citadel Securities, BNY and Nasdaq. That backing underscores how large institutions view tokenization as a strategic route to modernize market plumbing.
According to Matheison, there are about $300 trillion of high-quality liquid assets worldwide, yet only around 10%-11% of that stack — roughly $28 trillion — is employed as collateral at any given moment. However, this underutilization is driven less by appetite and more by operational frictions.
In traditional markets, firms must plan days in advance to move securities across borders. They must navigate settlement cycles, batch processing windows and market cut-off times, which create timing gaps and operational risk for cross-border collateral movements.
At a practical level, these constraints limit how much of those high-quality liquid assets can be put to work simultaneously, Matheison noted. That said, the Canton approach is designed to compress these frictions by synchronizing movements of securities and cash on the same institutional blockchain.
Using ledgers such as Canton for repos enables counterparties to transfer ownership in real time, rather than waiting for end-of-day netting or regional clearing windows. Moreover, continuous, around-the-clock settlement could allow balance sheets to be recycled several times a day, potentially boosting trading capacity and collateral efficiency.
By enabling real time settlement blockchain mechanisms, the network aims to support 24/7 transfers of government bond collateral and cash across multiple currencies. This is particularly relevant for cross-border funding markets where liquidity often needs to shift quickly between time zones.
Matheison argued that a permissioned institutional ledger can align legal ownership, settlement finality and risk controls within a single environment. As a result, institutions could use their balance sheets more dynamically, while preserving regulatory oversight and existing market roles such as custodians and central securities depositories.
The team behind Canton believes such an architecture can make high quality liquid assets more versatile, without fragmenting market infrastructure. However, the model still depends on broad adoption by large dealers, clearing houses and regulators to scale meaningfully.
The cross-border intraday deal illustrates how institutional blockchain collateral systems might coexist with current market rails, rather than replace them outright. Moreover, by supporting both securities and tokenized deposits, Canton is positioning itself as a shared settlement layer for interconnected financial products.
Industry participants are closely watching whether this first cross-border intraday repo leads to routine use of smart contract repo terms in institutional funding markets. If replicated at scale, similar structures could extend to other asset classes beyond gilts, from corporate bonds to securitized products.
Ultimately, advocates say the initiative shows how tokenized gilts on a shared ledger could help free up a far larger portion of the global collateral pool, while enabling faster, safer and more flexible cross-border funding operations.
In summary, the Canton Network pilot demonstrates that combining tokenized government bonds, programmable cash and smart contracts can turn a complex cross-border repo into an intraday, real-time transaction, potentially transforming how the $300 trillion collateral universe is deployed.
