Hong Kong Green Bonds Lock in 4.75% Rate as Inflation Stays Muted

Hong Kong’s retail green bond holders will receive the fixed rate floor of 4.75% for their fifth interest payment, the Hong Kong Monetary Authority announced on March 24, 2026. With local inflation running at just 1.28% on average, the fixed rate handily beat the inflation-linked floating rate.

The payment, scheduled for April 10, 2026, covers the series of retail green bonds maturing later this year (Stock Code: 4273). Under the bond’s structure, investors receive whichever rate is higher—the six-month average inflation rate or the 4.75% fixed floor.

Inflation Remains Subdued

Hong Kong’s consumer prices have stayed remarkably tame. The Composite Consumer Price Index showed year-on-year changes ranging from 1.10% to 1.70% between September 2025 and February 2026, averaging out to 1.28%.

That’s good news for bondholders locked into the fixed rate guarantee. When the government launched this series in September 2023, the 4.75% minimum was designed as a sweetener to attract retail investors—and it’s been doing the heavy lifting ever since.

The Bigger Picture

These bonds sit under the Government Sustainable Bond Programme, Hong Kong’s push to get everyday residents into green finance. The three-year instruments pay semi-annually, with rates reset each period based on the inflation-versus-fixed comparison.

For context, the previous 2025 maturity series (HKGB RGB 2505) carried a lower fixed rate of just 2.50% per annum. The jump to 4.75% for the current series reflected the higher rate environment when these bonds launched.

Secondary trading happens on the Stock Exchange of Hong Kong at clean prices, though retail holders typically buy and hold for the guaranteed returns rather than speculating on price movements.

What Comes Next

With the bonds maturing in 2026, holders have one more interest payment cycle before redemption. Given Hong Kong’s persistently low inflation environment, expect the fixed rate to continue dominating the calculation. For investors who bought at issue, the 4.75% annual return has outperformed most traditional savings products in the region.
