Current stress testing of banks is focused on the resiliency of individual banks to exogenous shocks. This column describes how the next generation of macroprudential stress tests aim to capture the endogenous nature of systemic risk caused by the interaction of all the institutions and markets making up the financial system.

There have been calls for restrictions on junk food advertising to tackle rising rates of obesity around the world. This column examines the likely effect of a ban on potato crisp advertising. Results suggest that the total quantity of crisps sold would fall by around 15% in the presence of a ban, or by 10% if firms respond with price cuts. The welfare benefits from this would depend on whether current advertising is persuasive, informative or complementary.
