Net zero financial institution alliances have been shaken up in recent months, with some banks, particularly those from the United States, withdrawing from alliances or pulling back on their commitments. In this context, a recent research paper explores the economic case for Net Zero banking, and explains why banks' self-interest, quite apart from ethical obligations to stakeholders, supports continued efforts in transitioning towards Net Zero goals.

The paper highlights two key ways in which banks gain from pursuing a Net Zero objective: reducing risks (default risk in particular); and capturing opportunities for financing growth in expanding segments related to decarbonization. The greatest challenge to banks’ efforts on decarbonisation is an underlying tension around both types of Net Zero financing.

Financing the decarbonisation of existing high-carbon companies can be associated with “exposure to stranded assets, green regulations, and carbon-emitting sectors [that] may mean greater risk for bank lending portfolios”. Meanwhile, financing new decarbonisation technology “might be seen as riskier, with growth orientations rather than stability properties”.

As regulators increase their focus on the impact of climate-related risks on financial stability, they will produce incentives for banks that over time help to resolve the tension in risk properties. Although this isn’t the focus of the research, which centres around economic incentives for banks to support the transition to Net Zero, the regulatory benefit of being able to demonstrate your preparation to manage climate risks is something—along with banks limiting their exposure to areas with high physical climate risk—that helps banks prepare for future policy changes and other climate-related risks. 

Each bank will approach the transition with different opportunities to pursue based on the heterogeneous characteristics of different institutions, and there won’t be a single, one-size-fits-all approach. This is likely to be particularly true with markets, such as many within the OIC, where transition risks intersect with physical risks, as well as with regulatory risks originating locally and those connected with key export markets.
