The Hong Kong SAR Government has launched a landmark issuance of HK$10 billion (approximately US $1.28 billion) in multi-currency digital green bonds, marking the largest sovereign-backed digital green bond offering to date.

The package spans HKD, RMB, USD and EUR tranches, with tenors up to five years — a notable extension for sovereign digital debt.

A key innovation: for the HKD and RMB tranches, investors were able to settle via tokenised central bank money (e-HKD and e-CNY), a first for primary bond settlement.

The move reflects Hong Kong’s ambition to strengthen its position as a green-finance hub, while also accelerating the evolution of its capital-markets infrastructure toward digital and programmable asset forms.

For institutional investors and regulators globally, the transaction offers a concrete model of how digital-bond issuance can scale without sacrificing credibility or environmental alignment.
