BIS and Tokenization: The Central Bankers' Bank Shapes Digital Finance Standards

The Bank for International Settlements occupies a unique position in the international financial architecture. It is simultaneously a bank (holding reserves for central banks), a research institution (producing some of the most rigorous academic work in monetary economics and financial stability), a standards-setting body (hosting the Basel Committee, CPMI, and FSB secretariats), and — increasingly — an active experimenter with new financial technologies through its Innovation Hub. No other institution combines all four roles.

In the digital finance era, this combination gives the BIS extraordinary influence over how central banks approach tokenization, CBDCs, and digital money infrastructure. When the BIS publishes research, central bank research departments read it. When BIS committees produce standards, they shape national legislation. When the BIS Innovation Hub runs experiments, central banks learn from the results without bearing the reputational risk of running their own experiments.

Agustin Carstens and the Institutional Voice

BIS General Manager Agustin Carstens has become the most prominent institutional voice of central bank skepticism toward decentralised crypto and enthusiasm for CBDC and regulated tokenization. His characterisation of Bitcoin as a “bubble, Ponzi scheme and environmental disaster” was among the most quoted institutional critiques of the first crypto cycle. But Carstens’ position has always been more nuanced than that summary suggests.

The critique is not of digital assets in principle but of decentralised, privately-issued digital assets that operate outside the monetary system that central banks manage. Carstens’ concern is that unanchored private digital money creates financial stability risks, monetary policy complications, and consumer protection failures that the existing regulatory framework cannot adequately address. The solution he has consistently advocated is not the abandonment of digital finance but the development of central bank-controlled digital currency infrastructure — CBDCs — that can provide the efficiency benefits of digital money without the monetary sovereignty implications of private alternatives.

Hyun Song Shin, the BIS’s Economic Adviser and Research Head, has provided the theoretical underpinning for this institutional position. Shin’s published research on stablecoins, CBDCs, and the monetary system is among the most cited in academic and policy circles. His framework distinguishes between the technological layer (where distributed ledger technology offers genuine innovation) and the monetary layer (where the anchor to sovereign currency and central bank balance sheet is non-negotiable). Tokenization built on this framework — tokenized traditional assets, regulated stablecoins backed by sovereign currency — is legitimate innovation. Decentralised money creation is not.

The Innovation Hub Network

What distinguishes the BIS from other international financial institutions is the Innovation Hub — a network of technology research centres established beginning in 2019, with nodes in Singapore, Hong Kong, London, Paris, Frankfurt, Stockholm, Toronto, and New York. The Hub runs experiments in partnership with central banks and, in some cases, with private financial institutions.

The Hub’s portfolio covers CBDC design, tokenization of financial assets, cyber security for financial infrastructure, regulatory technology, and green finance technology. Not all experiments succeed — the BIS is explicit that experimental outcomes, including negative results, are valuable. But the cumulative body of practical knowledge generated by Hub experiments has made the BIS the most empirically grounded international institution on digital finance technology.

The Hub operates by identifying technology questions that multiple central banks face simultaneously and running shared experiments rather than requiring each central bank to develop solutions independently. This is enormously efficient from a central bank perspective — the Reserve Bank of Singapore, the Hong Kong Monetary Authority, and the Bank of England all benefit from Hub experiments without each having to build its own research infrastructure.

Project Guardian: Institutional Tokenization

Project Guardian — the collaboration between MAS Singapore and the BIS Innovation Hub — is the Innovation Hub’s most watched tokenization experiment. It brought together major global banks to test tokenized bonds, foreign exchange, and fund units in regulated live environments. The banks involved — HSBC, JPMorgan, DBS, Standard Chartered, Citi — are not technology startups running conceptual proofs. They are the major institutions of the conventional financial system testing whether tokenized asset markets can function at institutional scale.

Guardian’s significance is that it generates empirical data rather than theoretical analysis. The policy implications — which existing regulations do not accommodate tokenized securities, which legal frameworks need amendment, which technical standards need development — emerge from real operational experience. This gives Guardian results a credibility in regulatory discussions that conceptual research cannot match.

Project mBridge: Multi-CBDC and Geopolitics

Project mBridge is the BIS Innovation Hub’s multi-CBDC platform, developed in partnership with the central banks of China, the UAE, Hong Kong, and Thailand. It enables cross-border payments using wholesale CBDCs — central bank digital money that moves between central banks directly rather than through the correspondent banking network.

The project has accumulated significant attention beyond the technical community because of its geopolitical implications. mBridge creates a cross-border settlement infrastructure that does not rely on the US dollar-denominated correspondent banking system. For participating jurisdictions, this provides a settlement alternative that is attractive both for efficiency reasons and, potentially, for sanctions-avoidance purposes.

The BIS withdrew from active participation in mBridge in 2024, under pressure from US political actors concerned about the platform’s potential use as a dollar-alternative settlement rail. The withdrawal was diplomatically managed — the BIS cited mBridge reaching maturity as an operational platform rather than explicitly acknowledging the political pressure — but the dynamics were transparent to observers. The episode illustrates the fundamental tension between the BIS’s technical and experimental work and the geopolitical realities that constrain international financial institution behaviour.

Annual Economic Report: Recurring Crypto Analysis

The BIS Annual Economic Report is perhaps the most consistently read annual document in central bank economics. Its treatment of crypto and digital assets has evolved substantially since the first substantive engagement with Bitcoin in the 2018 edition — which was broadly skeptical — through increasingly sophisticated analysis of stablecoin risks, DeFi systemic implications, and CBDC policy options.

The recurring crypto chapters serve an agenda-setting function for central bank economics departments globally. Topics that appear in the BIS Annual Economic Report become topics that central bank research teams study. Frameworks introduced in BIS analysis are frameworks that national CBDC and tokenization working groups adopt. The intellectual leadership is not imposed through authority but exercised through the quality and timeliness of the analysis.

The BIS’s unique combination of standard-setting responsibility, experimental infrastructure, and research capacity makes it the institution that, more than any other, will determine what the central bank digital finance ecosystem looks like over the next decade.
