The Bangko Sentral ng Pilipinas announced plans to develop a green taxonomy in January 2024, with Governor Eli Remolona identifying the classification framework as a central pillar of the central bank's strengthened sustainability agenda. The taxonomy is intended to increase transparency across the financial system, define which economic activities qualify as environmentally sustainable, and make the Philippines a more attractive destination for foreign capital directed at climate mitigation and adaptation projects. By establishing a credible definitional standard, the BSP aims to reduce the risk of greenwashing and give domestic issuers a clearer pathway to qualifying their instruments under internationally recognised sustainable finance frameworks.
The announcement positions the BSP among a growing number of central banks and financial regulators in South-East Asia that are building the institutional architecture needed to channel private capital towards green and transition finance. A robust taxonomy reduces the definitional ambiguity that can deter institutional investors — particularly those operating under their own internal ESG mandates — from committing to markets where the standards for labelling instruments as sustainable are still being developed. For the Philippines, which already has a meaningful presence in the ASEAN sustainable bond market, the taxonomy will provide a foundation for further growth.
RESERVE REQUIREMENT CUT ALREADY INCENTIVISING GREEN BONDS
Ahead of the taxonomy announcement, the BSP had already taken concrete steps to stimulate the market for sustainable debt. The central bank reduced the reserve requirement rate applicable to ESG bonds issued by banks from 3% to 0%, effectively lowering the funding cost for lenders that choose to raise capital through qualifying green, social or sustainability instruments. By removing the reserve requirement on such bonds, the BSP creates a direct financial incentive for domestic banks to tap ESG-focused investors, helping to build a pipeline of eligible assets that a formal taxonomy will further legitimise and standardise.
The reserve requirement concession reflects the BSP's dual role as both monetary authority and prudential regulator: by adjusting a routine liquidity management tool, it is able to tilt bank behaviour towards sustainability goals without prescribing specific lending mandates. Other central banks in the region have employed similar mechanisms, including targeted refinancing facilities and preferential treatment for green collateral in repurchase operations, suggesting that the BSP's approach is part of a broader regional trend rather than an isolated policy experiment.
PHILIPPINES ALREADY A SIGNIFICANT ASEAN SUSTAINABLE BOND ISSUER
The Philippines enters the taxonomy exercise from a position of relative strength in ASEAN sustainable capital markets. Philippine issuers account for approximately 27% of the total USD 57.2 billion in ASEAN-labelled green, social and sustainability bonds outstanding, equivalent to approximately USD 15.3 billion. That share, which places the country among the leading contributors to the regional sustainable bond market, gives the taxonomy development an added urgency: a robust classification framework will help ensure that the instruments already in the market, and those yet to be issued, meet standards rigorous enough to satisfy the due-diligence requirements of international investors and the methodological standards applied by major sustainability rating agencies.
Governor Remolona indicated that the taxonomy development forms part of a broader suite of sustainability initiatives at the BSP, which has been integrating environmental considerations into its assessment of banks' risk management practices and expanding its climate risk supervision framework. The central bank has not disclosed a specific target date for the publication of the taxonomy, but the January 2024 announcement signals that the technical work on the framework is actively progressing, with the BSP drawing on the experience of peer regulators in the European Union, ASEAN and beyond as it shapes the final classification structure.
