Last month, the US Office of the Comptroller of the Currency (OCC) issued the second part of its initiative to address the effects of climate change—draft principles for managing exposure to climate-related financial risks. Those principles and the OCC's earlier call to action to bank boards portend that the rapid implementation of climate risk management practices could occupy a significant amount of management and board time this year. And while targeted at OCC-regulated banks with over $100 billion in total assets, the draft principles may be of interest to banking organizations of all sizes and charters. Mayer Brown partners Paul Forrester and Matthew Bisanz and associate Kerri Webb discuss how to understand these new OCC principles.
