World Bank bond-i: When a Bond Changes Hands, So Does the Record
In 2018, the World Bank and CBA put an Australian-dollar bond on a private blockchain platform. The experiment followed the bond beyond issuance, into trading and repayment, and exposed the work of making a shared system reusable.
3-Minute Fast Briefing
- The ParadoxThe 2018 bond-i raised A$110 million; its settlement date was August 28, distinct from the launch announcement.
- The Turning PointThe platform used a private Ethereum blockchain operated by the World Bank and CBA, not the public Ethereum mainnet.
- The LegacySecondary trading and a later tap extended the experiment; reusable market infrastructure remained a separate challenge.

A familiar instrument on a different register
On August 24, 2018, Commonwealth Bank of Australia announced that the World Bank’s bond-i had raised A$110 million. Its terms were recognizable: a two-year bond, denominated in Australian dollars, with interest payments and a maturity date. Settlement was scheduled for August 28. The unusual part was the platform used to manage its record. A blockchain bond was still a bond: changing the register did not turn the investment into ether.[1]
CBA’s earlier announcement specified a private Ethereum blockchain, operated by the World Bank in Washington and CBA in Sydney. That distinction matters. Using Ethereum technology did not mean publishing the bond on the open Ethereum network. The project brought known institutions into a shared system. Its central question was how participants could work from an agreed record as the instrument moved through its life.[2]
The second owner matters
A successful launch cannot test everything a bond needs. Once one investor sells to another, the record must follow the new holder. In May 2019, CBA reported a completed secondary transaction recorded on the distributed ledger, developed with the World Bank and market maker TD Securities. The experiment had moved beyond recording who received the bond at issuance to recording a later trade.[3]
In August 2019, an additional A$50 million enlarged the same bond. CBA, RBC Capital Markets and TD Securities jointly managed the tap. This was another practical test: more capital and more participants had to use the platform. CBA also described settlement, custody and regulatory compliance as areas for further efficiency work. Recording a trade was evidence of a working function, not proof that every surrounding process had disappeared.[4]
After the experiment, a market still has to work
A 2023 World Bank retrospective described the Australian-dollar bond’s issuance, servicing and redemption across 2018–2020 as successful. It also identified a wider obstacle: such experiments often required expensive, time-consuming, one-off platforms. A working transaction and an easily reusable market system were different achievements.[5]
That is what makes bond-i more interesting than the phrase “a bond on a blockchain.” Its launch, later trading and additional issuance show a project learning across several stages of one instrument’s life. The remaining question was how the next issuer and the next investor could use comparable infrastructure without rebuilding the whole arrangement. The shared record was the beginning of that work.[1][3][4][5]
