Part two of two. The concluding part of the documentary looks at how the Bank is preparing for all eventualities, including the possible economic shock of Brexit. In the Financial Stability area, Executive Director Alex Brazier and his team assess whether the UK's financial system is strong enough to cope with a disorderly Brexit. To find out, they subject the country's biggest high-street banks to Stress Tests, one of the most thorough economics examinations they face. The tests will reveal if they hold enough contingency funds to withstand a no-deal situation. Alongside the economic danger that a disorderly Brexit could pose, the Bank also deals with longer-term threats. Cameras follow Governor Mark Carney and his team to New York, where, alongside the world's leading politicians, he announces a major breakthrough in the Bank's efforts to protect the global economy from the effects of climate change
