I will focus my talk on other no less important reforms, implemented in a particularly disrupted context: the financial regulations introduced in the wake of the 2007–2009 crisis. Is there any need to recall the disastrous consequences that this crisis inflicted on the real economy, the social dramas, and the democratic fragmentation with the rise of populism? Financial stability is therefore a common good that needs to be guaranteed. It is one of the three core tasks of the Banque de France, alongside monetary strategy and services to the economy. We have been striving to achieve it in the international bodies that coordinated the financial reforms after the crisis. The urgency of the situation required rapid and effective action, and as early as April 2009, the G20 launched a global concerted action plan. This afternoon, I would like to start by explaining the ambivalent relationship between finance and growth, and the attendant need for financial regulation. Then, I will discuss at greater length what has been done, with an initial assessment of our achievements. Lastly, I will consider our challenges for the future.
