On 31 March 2023 we joined Positive Money, Financial Inclusion Centre, Transparency Task Force, New Economics Foundation and Finance Watch in signing this joint statement on the implementation of the Basel 3.1 standards. The Basel standards aim to prevent future banking crises by setting ‘prudential’ standards for banks that aim to ensure they are safe, sound institutions, and reduce the risk in the system. Our joint letter argues that the UK’s implementation of these global standards must ensure that high standards across the UK banking system, and that future rules should integrate climate risks.
