About the blog
The BCC blog is a space of exchange among BCC stakeholders about topics of interest in the realm of central banking. It offers a space where latest trends can be discussed, practical experiences be shared, and a BCC community be developed.
The BCC programme, funded by SECO and implemented by The Graduate Institute, Geneva aims to support partner central banks in emerging countries in building the analytical and technical expertise to conduct effective monetary policy, promote stable and efficient financial sector, and be more operationally sustainable.

Should disaster risk and climate change be introduced in macroprudential regulation and supervision? - by Gregorio Belaunde
Gregorio Belaunde, Independent Risk Management Consultant
Should central banks care about climate risk?
When the new President of the ECB, Christine Lagarde, said on December 2, 2019 that fighting against climate change was a critical mission for the ECB, she was met with comments that this not being ECB’s mandate and that it could even affect its independence. According to Jerome Powell, Chairman of the U.S. FED, climate change is not a job for the Bank. Similarly, for a long time, the Basel Committee on Banking Supervision (BCBS) did not seem to think that it had a role to play in this field as a standards-setter.
The debate is rapidly moving, however. Mark Carney, while at the helm of the Bank of England and of the Basel-based FSB led efforts to include climate change as a key issue for central banks and financial regulators. This inspired the creation in December 2017 of a group of central banks and supervisors, the Network for Greening the Financial System (NGFS), which issued in April 2019 a Call for Action with, as 1st Recommendation, “Integrating climate-related risks into financial stability monitoring and micro‑supervision”. The BCBS joined this network in June. In its October 2019 Global Financial Stability Report the IMF mentioned climate change as a key issue, just after joining the NGFS. This January, the BIS released its first paper on this, a book called “The Green Swan”, where it states that “Central banks can have an additional role to play in helping coordinate the measures to fight climate change”. So, the answer to the question laid out at the beginning is now a clear Yes. This said, both the IMF and the BIS stress that integrating climate change into financial stability monitoring is a significant challenge, due to radical uncertainties. So, the complete answer is rather: Yes, but how exactly?
I think that the problem is even more relevant and urgent for emerging and developing countries and their financial regulators/supervisors, in coordination with Ministries of Finance due to their fiscal risk management role. This particular relevance stems from the fact that the impacts of climate change and related hazards on their GDP, and therefore on the quality of the credit exposures, are inevitably much higher, given the smaller size of their economies, as international experience shows. Concurrently, those countries should not forget that the problem is not only climate change, but also disaster risk, which considers a broader range of events than weather-related ones, notably earthquakes. This has been reminded in a Standard and Poor’s study of 2015 about the impact that “natural” disasters could have on sovereign ratings, and in different studies concerning the serious “disaster-insurance gap” that those countries face. Both factors combined can cause steep increases in non-performing loans (NPLs), with a systemic impact if several significant disasters hit in a short period of time, or in case of a large-scale disaster.
Therefore, the financial regulators/supervisors should urgently integrate climate change and disaster risk into their macro-prudential regulation and supervision, with a related translation into micro-supervision, in the same way as they include risks related to borrowings and loans in foreign currency, for instance. A broad range of very concrete measures can be adopted rapidly. These include, inter alia, and as those that should be prioritized:
