Reforming climate finance: unlocking funds from multilateral development banks

Multilateral development banks (MDBs) provided approximately USD 125 billion for climate finance in 2023, a 26% increase from 2022, yet this represents only about 1% of the USD 8.6 trillion needed annually by 2030. A G20 expert panel and credit rating agencies suggest that reforming capital adequacy frameworks (CAFs)—by increasing risk tolerance and leveraging callable capital—could unlock hundreds of billions of dollars in additional lending without risking AAA credit ratings. Specifically, current CAF progress could unlock up to USD 357 billion in lending headroom over the next decade, while S&P estimates potential increases of USD 500 billion to USD 1 trillion. The briefing also highlights the under-utilisation of guarantees, which attract USD 1.5 of private capital for every USD 1 invested, and equity finance, which currently accounts for only 1.8% of commitments. These MDB expansions are viewed as critical for the New Collective Quantified Goal (NCQG), though experts argue MDB lending should complement rather than replace grant-based finance.

• MDBs have the potential to unlock hundreds of billions of dollars in additional climate finance through reforms to their capital adequacy frameworks (CAFs), which currently limit lending due to risk aversion and a desire to maintain AAA credit ratings. A G20 expert panel noted these reforms could unlock significant funds while posing "negligible risk to their financial stability."
• Current progress on CAF reforms among seven monitored MDBs could provide up to USD 357 billion in additional lending headroom over the next ten years. Further potential exists according to rating agencies: S&P suggests USD 500 billion to USD 1 trillion more could be invested, and Fitch Ratings estimates nearly USD 480 billion more could be lent before risking downgrades.
• MDB climate finance is growing but remains a small fraction of total global needs. In 2023, MDBs provided about USD 125 billion, which is a 26% increase from the USD 99.45 billion provided in 2022. This total represents approximately 1% of the USD 8.6 trillion required annually by 2030 for global climate action plans.
• MDBs under-utilise high-leverage financial tools. Guarantees, which attract an average of USD 1.5 in private capital per USD 1 of MDB investment, account for only 4% of total climate finance commitments. Equity finance is even lower, making up only 1.8% of commitments in emerging markets and developing economies.
• MDB funding is expected to be a central component of the New Collective Quantified Goal (NCQG), with a G20 expert group recommending that USD 260 billion be channelled annually through MDBs, 78% of which should be non-concessional lending.
