Similar to key monetary innovations of centuriespast, the tokenisation of money and financial assets has the potential to expand the universe of possiblecontracting outcomes to support economic growth.2need for scalable platforms, regulatory clarity and robust infrastructure.At $80 trillion, government debt stands as the largest and most critical global asset market, and acornerstone of the financial system. Government bonds provide a safe asset for investors, and underpinmonetary policy implementation, collateral management and financial stability. Bond markets are apromising setting for tokenisation, as current trading and settlement practices involve a complex web ofintermediaries, messaging instructions, reconciliation efforts and money flows. The tokenisation ofgovernmentbonds could enhance liquidity by reducing transaction times and increasing marketaccessibility. It could also potentially support collateral management and monetary policy operations byenabling the integration of bonds with other tokenised assets, allowing for automated collateral transfersand efficient use of assets in repurchase agreements (repos) or central bank operations.This Bulletin explores the case for tokenised government bonds. While bond tokenisation is on therise in both number and volume of issuances, the market remains in its infancy. We build a data set ofprivate and government tokenised bonds. Our sample features 39 tokenised bonds, of which 24 have beenissued by corporations and 15 by governments or supranationals.3their conventional (ie non-tokenised) counterparts with the same issuer, currency and coupon type.

They serve as a critical sourceof financing for governments, a trusted savings vehicle for households and businesses and the key locusof central banks’ monetary policy operations. They provide the safest and most liquid form of collateral insecured money markets and derivatives, and act as a benchmark asset to price risk across the economy.Bid-ask spreads are generally narrower for government bonds than for other asset classes, reflecting theirlow credit risk and large investor base – especia
