Asia’s best ESG deal 2025: Hong Kong government’s HK$6 billion equivalent multi-currency digital bond

When Hong Kong’s government sought to issue its second digital bond in February 2024, it confronted a dual mandate: advance sustainable finance while proving blockchain’s viability in institutional capital markets. It turned to Crédit Agricole to orchestrate what would become a watershed moment for sustainable finance in Asia. The resulting HK$6 billion ($764 million) equivalent multi-currency offering didn’t just break records – it demonstrated how blockchain technology could finally deliver on its promise.  

This was the largest digital bond any government had issued globally; it marked several firsts that reshaped market expectations. The concurrent issuance across four currencies – US dollars, euros, Hong Kong dollars and, crucially, offshore renminbi – created a template for international digital securities.  

The US dollar tranche set a record as the largest offshore digital US dollar bond to date. The offshore renminbi tranche represented the first digital bond ever denominated in China’s offshore currency, signalling Beijing’s quiet endorsement of Hong Kong’s fintech ambitions. 

Crédit Agricole’s role went beyond traditional underwriting. As joint green structuring bank, the French lender helped design a framework that satisfied both environmental standards and technological innovation. The proceeds would fund nine categories of green projects, from renewable energy to pollution prevention and nature conservation. 

But the real breakthrough lay in the plumbing. Working with Hong Kong’s Central Moneymarkets Unit, Crédit Agricole helped engineer connections to Euroclear and Clearstream – the two major clearing houses that serve as the circulatory system of global bond markets. International investors could buy and hold the digital securities using their existing accounts, just as they would with traditional bonds. This eliminated the need for new platform onboarding or operational changes, addressing a major adoption barrier.

While maintaining this investor convenience, the digital format automated issuance, trading and settlement through blockchain and smart contracts, reducing manual paperwork and administrative steps. Settlement times compressed from the standard two days to near-instantaneous completion.  

The transaction built on Crédit Agricole’s experience from Hong Kong’s inaugural digital green bond a year earlier – an HK$800 million pilot that tested the concept. That inaugural deal proved the technology worked; this follow-up demonstrated it could scale.  

The timing proved prescient. As global investors increasingly scrutinise environmental credentials while demanding operational efficiency, Hong Kong positioned itself at the intersection of two powerful trends. The deal attracted buyers who might typically avoid emerging market green bonds due to operational complexity. By simplifying the process through blockchain, Crédit Agricole helped expand the potential investor base for sustainable finance in Asia. 

For Crédit Agricole, the transaction validated a strategic bet on Asia’s digital finance infrastructure. The bank’s ability to navigate between Hong Kong’s ambitions, international clearing systems, and environmental standards showcased the kind of technical expertise that increasingly differentiates leading investment banks.
