British International Investment (BII), the UK’s development finance institution and impact investor, has backed the inaugural international green bond programme by Ho Chi Minh City Development Commercial Bank (HDBank) to support Vietnam’s journey towards a sustainable future.
BII and the Dutch entrepreneurial development bank, FMO, have committed $20 million and $30 million, respectively, to the second tranche of HDBank’s green bonds, following IFC’s $50 million in the first tranche. This collaboration marks a major milestone in strengthening Vietnam’s green finance ecosystem and accelerating its energy transition.
The proceeds will support solar energy, electric vehicles, green buildings, and energy-saving solutions, helping to reduce approximately 102,000 tons of CO₂ over 10 years and contributing to Vietnam’s Net Zero 2050 commitment.
Srini Nagarajan, Managing Director and Head of Asia at BII, said: “Vietnam continues to be a priority market for BII as we invest in South-East Asia’s green energy transition. Our participation in HDBank’s inaugural green bond programme, together with IFC and FMO, sends a strong signal about the readiness and potential of Vietnam’s sustainable finance ecosystem. This will help attract more capital into climate responsible projects, overall, supporting the country’s net-zero 2050 ambitions.”
This investment demonstrates BII’s commitment to driving climate finance in South-East Asia. By supporting HDBank’s green bond issuance, BII is helping to unlock more capital for Vietnam’s energy transition and sustainable growth.
