The Hong Kong government has priced around HK$20 billion in digital green bonds across four currencies, what it describes as the world's largest digital bond issuance. The announcement from the Hong Kong Monetary Authority on 29 September 2026 also marks a settlement first: the Hong Kong dollar tranche is the first digital bond to bring HKD tokenised deposits into its primary issuance settlement.
This is the Government of the Hong Kong Special Administrative Region's fourth digital bond offering since 2023. It was issued under the Government Sustainable Bond Programme and priced on 28 September after a virtual roadshow. According to the HKMA, subscription ratios ranged from 1.3 to 11.3 times across the four currencies.
Four currencies, four tenors
The offering was split into four tranches, each in a different currency and maturity:
- Hong Kong dollar: HKD 5.5 billion over two years at 3.80%.
- Renminbi: RMB 7.5 billion over five years at 1.65%.
- US dollar: USD 200 million over three years at 5.023%.
- Euro: EUR 450 million over four years at 3.734%.
Fitch, Moody's and S&P rate the bonds AA-, Aa3 and AA+ respectively, in line with Hong Kong's own long-term rating. The notes settle one business day after trade, are governed by Hong Kong law, and are listed on the Hong Kong Stock Exchange. The money raised is earmarked for green projects that qualify under the government's Green Bond Framework, either as new financing or to refinance existing work. Vigeo Eiris reviewed the framework and issued a Second Party Opinion, and the Hong Kong Quality Assurance Agency certified the bonds at the pre-issuance stage of its green finance certification scheme.
"The HKSAR Government has successfully issued digital green bonds for the fourth time, totalling HK$20 billion, which is the largest issuance of its kind globally. The offering was oversubscribed, demonstrating strong market appetite for tokenised products issued in Hong Kong," by Paul Chan, Financial Secretary of the HKSAR Government
Tokenised deposits join the settlement menu
This time, the new element is how the bonds can be paid for. The HKMA said the latest issuance keeps the traditional settlement rail and the tokenised central bank money option introduced in the previous issuance. For the HKD tranche, it adds a third route: tokenised deposits, enabled by EnsembleTX, have been built into the primary issuance settlement process.
The HKMA calls this the world's first digital bond to integrate tokenised deposits in Hong Kong dollars. This brings the different forms of digital money closer together and opens the way to testing what programmable money can do in bond markets.
Tokenised settlement in central bank money is also a focus in Europe, where the Eurosystem recently launched Pontes to settle wholesale tokenised asset transactions in central bank money.
Standards and market plumbing
The offering also adopts the International Capital Market Association's latest Bond Data Taxonomy, Version 2.0. The taxonomy is a standardised, machine-readable language for a bond's key economic terms, key dates and other details usually found in a term sheet, such as governing law, parties, ratings and selling restrictions. The HKMA said Version 2.0 extends coverage to more complex structures and to the full bond lifecycle, and that using it should help keep bond data consistent, let different systems work with it, and automate processing from issuance to maturity. Common data standards of this kind speak directly to the fragmentation risks facing tokenised markets.
Clearing and settlement run through the Central Moneymarkets Unit (CMU), operated by the HKMA and linked to Euroclear and Clearstream. Settlement through the CMU benefits from statutory settlement finality under Hong Kong law. HSBC Orion serves as the digital assets platform, with HSBC as platform provider, trustee and principal paying agent.
Thirteen banks worked on the deal. Eight of them, including HSBC, Bank of China (Hong Kong), J.P. Morgan and Standard Chartered Bank, led it as joint global coordinators, with Barclays, Citigroup, Deutsche Bank, Société Générale and UBS also serving as lead managers and bookrunners. Three law firms advised: Allen Overy Shearman Sterling for the government, Ashurst Perkins Coie Hong Kong for HSBC as platform provider, and Linklaters for the banks and agents.
"The Policy Statement 2.0 on the Development of Digital Assets in Hong Kong released last year highlighted the focuses on the expansion of the suite of tokenised products and the advancement of use cases and cross-sectoral collaboration. The Chief Executive's 2026 Policy Address further stated that the Government will work to broaden use cases and popularise digital bonds," by Christopher Hui, Secretary for Financial Services and the Treasury of the HKSAR Government
Why it matters
For the government, the issuance is part of an ongoing programme rather than a one-off. The Financial Secretary said the government will continue to issue tokenised bonds regularly and expand the use cases for the underlying technologies. That fits alongside Hong Kong's wider digital asset framework, which also saw the HKDAP stablecoin go live through licensed distributors in August.
For banks and bond market participants, the practical change is that tokenised deposits have now been built into the primary settlement of a government bond, alongside tokenised central bank money and conventional settlement. Together with the move to ICMA's machine-readable taxonomy, the HKMA presents the issuance as a step towards a more integrated and automated digital bond market.
"This fourth issuance reinforces our commitment to stay ahead in the digital finance space, continues to unlock new synergies across digital infrastructures, and deepens our digital asset ecosystem. We are encouraged by the strong investor demand and the expanding market participation," by Eddie Yue, Chief Executive of the Hong Kong Monetary Authority
