UK digital gilt pilot faces a $34 million stablecoin problem

The UK Treasury, Bank of England and FCA are targeting a first transaction for the Digital Gilt Instrument, or DIGIT, by early 2027 via HSBC and the London Stock Exchange Group, according to a government announcement.

"The challenge then, as now, was how to settle that bond on-chain using a counterparty risk-free settlement asset, and we do not yet have a compelling solution," Jannah Patchay, founder of Markets Evolution, said.

The UK gilt market sees aggregate daily trading volumes exceeding 45 billion pounds, and the Wholesale Digital Markets Champion report projects global tokenized real-world assets could grow to $88 trillion by 2035. Yet only four pound-pegged stablecoins exist, with the largest — TGBP — holding a market capitalization of $34.2 million in a global stablecoin market valued at $300 billion, according to CoinGecko data. The UK's crypto regulatory framework does not take effect until October 2027.

Without a viable onchain settlement asset, the DIGIT pilot risks becoming an infrastructure demonstration that cannot scale into a functioning capital market, potentially pushing liquidity and innovation to jurisdictions with mature stablecoin regimes in the EU and US.

The settlement gap that seven years of pilots haven't solved

Santander issued a tokenized corporate sterling-denominated bond in 2019, proving that bonds can be represented on a distributed ledger. What no pilot has solved is how to settle that bond on the same ledger using cash that carries no counterparty risk. The UK's settlement finality laws do not account for distributed ledgers, creating a regulatory gap where transactions could be legally reversed if a participant becomes insolvent.

Patchay said the next step is building market infrastructure around compliant sterling stablecoins, which she described as having "significant potential to catalyze adoption across the market by providing that onchain settlement mechanism."

The Digital Securities Sandbox now allows certain firms to use stablecoins as the settlement asset, creating a live — albeit capped — environment where a tokenized security and a stablecoin cash leg can move together on the same ledger. The Wholesale Digital Markets Champion taskforce has deployed nine industry action groups targeting a live, end-to-end tokenized repo transaction by spring 2027.

A regulatory timeline that trails the market

The FCA published its final cryptoasset rules on June 30, 2026, including policy statements on stablecoin issuance, market abuse, and a prudential regime for crypto firms. The authorization gateway opens September 30, 2026, and the application window closes February 28, 2027, with the full regime going live on October 25, 2027.

The Bank of England's near-final stablecoin rules impose a roughly 40 billion pound per-issuer issuance limit and require 30% of backing assets to sit in unremunerated reserves at the central bank. The EU's MiCA regime has been fully applicable since December 2024, and the US GENIUS Act became law in July 2025 — meaning the UK will have regulated alternatives available for three years before its own framework is operational.

Varun Paul, global business lead for central banks and financial market infrastructure at Fireblocks, said the DIGIT project has enough institutional backing from the Treasury, Bank of England and FCA that it would be difficult to reverse despite the recent change in prime minister. Andy Burnham took office on July 20, replacing Keir Starmer, with John Healey succeeding Rachel Reeves as chancellor.

"If anything, I think this might support increased demand for UK debt at a convenient time for the UK government," Paul said.

A separate analysis by Barclays argued that the value of digital government bonds lies not in their issuance but in their ability to support repo and collateral management across secondary markets. The Bank of England has confirmed it will open CHAPS settlement from 01:30 a.m. starting September 2027, a first step toward near 24/7 operation.
