For the past three years, the Bank of England (the Bank) has carried out an annual ‘stress test’ of the UK’s largest banks. To do this, it designed a narrative-based stress scenario in 2014 and 2015. The goal was to determine the banking sector’s resilience to pertinent threats, like recessions or a sharp fall in house prices.
