Christoffer Kok, head of the stress test modelling division of the ECB's directorate general for macroprudential policy and financial stability, joins Emma McGarthy, head of OMFIF’s Sustainable Policy Institute, to discuss the results of the stress test, approaches and methodologies taken and lessons learnt.
