It’s also crucial that these efforts are coordinated at the global level, given the global dimension of the risks and the potential spillovers that can arise through interconnections between the real and financial sectors. In this regard, at the Basel Committee on Banking Supervision (BCBS), we are conducting a “gap analysis” to identify areas in the current Basel Framework where climate-related financial risks may not be adequately addressed or are not captured. This gap analysis will be comprehensive in nature, and will cover regulatory, supervisory and disclosure elements. Building on the analysis, we plan to explore practical solutions to address any identified gaps. In addition to a set of principles or guidelines on effective supervisory practices for assessing climate-related financial risks, the Committee will explore whether any policy measures under the regulatory framework should be taken, and how the Basel Committee could support international efforts related to the development of globally consistently sustainability reporting requirements. Importantly, any changes proposed by the Basel Committee to its regulatory framework would be in pursuit of its mandate to strengthen the regulation, supervision and practices of banks worldwide with the purpose of enhancing financial stability. As to monetary policy, central banks should definitely be a part of this optimal policy mix as well. Here, it is useful to distinguish between central banks' monetary policy operations and those other operations not related to our monetary policy mandates. I will start with the latter, if only because it is easier to draw some conclusions in this case.

Therefore, we must make sure that financial firms address these risks. In particular, we should contribute to identifying climate-risk drivers and their transmission channels, to the adequate measurement of the economic and financial impact of the different risks, and to the definition and development of the potential mitigation and riskreduction measures. If we succeed in incorporating these risks into the decisions of the financial sector, this will translate into a change in the relative prices of financial instruments. And, in turn, that will help to internalise those consequences originating from both transition and physical risks that affect directly providers and users of funds. This will be a powerful and much-needed complement to the use of the fiscal and environmental instruments that are needed to fight against climate change. In practical terms, climate risk can probably be captured in the traditional financial risk categories (credit, market, liquidity or reputational risks). However, several crucial limitations and challenges are coming to light when trying to measure these risks. In particular, there are few sufficiently deep and harmonised databases to analyse and understand the potential effects of physical and transition risks. Data granularity is particularly important given the high heterogeneity of the potential impacts. And, while we are working hard to improve available information, we lack sufficient historical depth to be able to use the past as a guide to estimate future developments.
