Finance is one of the largest sectors of the UK economy. Around 400,000 people are employed in financial 3  services in London alone, 1.1 million across the country as whole. Their enterprise contributes £ billion to our national income, £ billion to our exports and £ billion to the Exchequer, equivalent to two-thirds of the NHS budget. 4  Your work matters because finance is not an end in itself; financial markets serve the real economy. By financing firms that hire, invest and expand, markets drive growth. By opening up cross border trade and investment, they create new opportunities for businesses and savers. By transferring risks to those most willing and able to bear them, markets help households and businesses insure against the unexpected. 1  See Fair and Effective Markets Review Final Report, HM Treasury, Bank of England and FCA (June 2015).

The Problem  Though markets are generally a force for good, markets can go wrong.

In this context, and as part of our main responsibility to guarantee the stability of the financial system, we - regulatory and supervisory authorities - must ensure that the materialisation of climate risks does not endanger financial stability. Therefore, we must make sure that financial firms address these risks. In particular, we should contribute to identifying climate-risk drivers and their transmission channels, to the adequate measurement of the economic and financial impact of the different risks, and to the definition and development of the potential mitigation and riskreduction measures. If we succeed in incorporating these risks into the decisions of the financial sector, this will translate into a change in the relative prices of financial instruments. And, in turn, that will help to internalise those consequences originating from both transition and physical risks that affect directly providers and users of funds. This will be a powerful and much-needed complement to the use of the fiscal and environmental instruments that are needed to fight against climate change. In practical terms, climate risk can probably be captured in the traditional financial risk categories (credit, market, liquidity or reputational risks). However, several crucial limitations and challenges are coming to light when trying to measure these risks. In particular, there are few sufficiently deep and harmonised databases to analyse and understand the potential effects of physical and transition risks. Data granularity is particularly important given the high heterogeneity of the potential impacts.
