Digital money foundation

Digital money and tokenisation are often discussed in terms of technological possibility. This new series asks a narrower economic question: when does blockchain or tokenisation add marginal value compared with existing financial instruments, schemes and infrastructures?

The economic rationale of blockchain

October 2026

Blockchain’s distinctive contribution lies in governance and infrastructure economics. Its relevance depends on where it enters the financial transaction stack and whether its marginal benefit exceeds the cost and complexity of adding another layer to the financial system.

Blockchain in payments: from technological possibility to economic rationale

8 October 2026

This is to share that I had the pleasure to participate in a research conference organised by the Bangko Sentral ng Pilipinas and Reinventing Bretton Woods Committee in Cebu, Philippines on 7 October. As blockchain continues to be proposed as a solution to payment problems, I wanted to ask: what actually is the economic rationale for using blockchain?[...]

Sibos: SWIFT ledger—is Swift really enabling payments in seconds?

30 September 2026

I was struck by how central blockchain was to Swift's Sibos 2026 opening plenary presentation on 28 September—“tokenised value has become truly embedded across payments and securities”—in the references to the new Swift ledger. The Swift blockchain-enabled ledger promises real-time, 24/7 cross-border payments. But what actually moves in real time?[...]

Money: What is actually new with tokenisation

14 September 2026

[...] Tokenisation is particularly conducive to representing money as a transferable, bearer-like instrument where control over the token can serve as the functional equivalent of possession. This fundamentally changes money relationships. Money can evolve from being highly intermediated to money that can be moved peer-to-peer (programmability also offers some important new functionality).[...]

Recent commentary

Economics Advisory,

Multi-issuer stablecoins can in principle be subject to redemption requests for stablecoins issued by any of the multiple issuers. In the EU, it has led to a debate about the adequacy of current provisions under the Markets in Crypto Assets Regulation (MiCAR). However, the current debate risks unduly conflating technical and operational fungibility with statutory claims. MiCAR unambiguously designates a stablecoin as a claim against the issuer. However, traceability of stablecoins is necessary to be consistent with MiCAR provisions.

Economics Advisory,

The notion of singleness of money has been used increasingly to qualify payment instruments as money.Stablecoins have been labelled as “failing the test of singleness.”

The notion of singleness has its historical foundation as singleness of currency in the establishment of monetary unions and fungibility under decentralised currency issuance. The concept needs to be revisited to ensure it can guide public policies effectively and does not lead to an unwarranted bias against certain monies.

Economics Advisory,

The emergence of stablecoins has raised concerns about their potential impact on the transmission of monetary policy and financial stability. At first sight, there is no compelling evidence suggesting that stablecoins similar to other prepaid instruments may impair monetary policy. The impact will likely depend largely on possible shifts in preference for holding transaction balances, a recomposition of bank liabilities and risks of increasing dollarisation but will be highly dependent on initial local conditions.[...]

Economics Advisory,

Decentralised finance now forms an integral part of the wider public policy discussion, including at the highest level. But I would argue often for the wrong reasons. I believe the discussion would be far more advanced if there were a greater common understanding of why and how certain elements of decentralised finance could have a major impact on the financial system. [...]

LSE Business Review Blog,

While concerns about stablecoins and their possible impact on financial stability remain, the instrument is not as new as people may assume. One country within the United Kingdom has one of the world’s oldest stablecoin regimes – in paper form. Scottish banknotes offer a reminder that the co-existence of stablecoins with other monies need not be controversial. Moreover, Scottish banks seem able to leverage existing regulation to move sterling “on-chain”.[...]

Which is the fairest of all tokenised monies

OMFIF Digital Monetary Institute, 13 March 2026

If widely adopted, tokenised money market funds may become one of the most consequential innovations in wholesale liquidity management.

As markets explore tokenised deposits and stablecoins, tokenised money market fund shares deserve equal attention, given their high credit quality, interest-bearing nature and institutional familiarity. Not only does tokenisation bring considerable benefits to money market fund shares, it changes how institutional liquidity is managed, shifting it from redemption towards circulation. It transforms money market funds from a passive savings vehicle to a multi-purpose financial instrument. [...]

The UK needs to press ahead with digital gilts plans

Financial Times, 29 January 2026

The UK government has been preparing to launch the most consequential state initiatives on the tokenisation of financial assets. The UK now needs to press ahead with a decision on the tender and subsequent development. The instrument, dubbed the Digit, could be the catalyst that brings tokenised money and assets more into the financial mainstream. While some countries like China have issued digital currencies, this would be the first issuance directly on a blockchain of tokenised treasury security by a G7 country. [...]
