François Villeroy de Galhau: Central banks’ response to the “tragedy on the horizon” Speech by Mr François Villeroy de Galhau, Governor of the Bank of France, at the SUERF – Online Conference, 14 October 2020. * * * Ladies and Gentlemen, I am very happy to join you today for this discussion that, although virtual, will be very real in terms of the strength of the ideas put forward. I am grateful to Michala Marcussen for offering me the opportunity to give this speech on such a dense topic: central banks’ response to the “tragedy on the horizon”. Faced with an unpredictable shock, the past eight months have driven the global economy into uncharted territory. However, one danger is certainly looming larger at the moment : our lasting addiction to public debt. Let me be clear: in the face of the unprecedented covid-shock, a massive and one-off recourse to public debt financing was both inevitable and desirable. However, we have entered this crisis with public debt levels, which were already very high in most countries, with few notable exceptions. The continuous rise of public debt, along with climate change, represent two of the main long-run challenges that we face today. In his famous 2015 speech, Mark Carney spoke of climate change as the “tragedy of the horizon”. With this, he meant that this tragedy is inevitable if we do not act, but it is in the long term, possibly leading to a “status quo bias”.
The exit from exceptional monetary measures should be fully in the hands of the central bank and guided by its mandate of price stability. Fiscal authorities must also be credible and give guidance on their future actions, by committing to tightening the stance when the economy has recovered. They should follow a stronger countercyclical fiscal policy in good times, to create the space that is necessary in bad times. What Blanchard and Summers5 call “semiautomatic stabilizers” – stabilising fiscal policies that operate according to predefined triggers – could be an avenue worth exploring. Let me add as a conclusion that, against this backdrop, the Next Generation EU package constitutes a new and innovative element of the European fiscal framework, which contributes to a sounder policy-mix. Beyond the most recent political and institutional discussions, which belong to elected leaders, a quick implementation of this European Recovery Fund is an economic must. This innovation, while still a one-off, could also imply lessons for the Economic and Monetary Union, which from the start has lacked a permanent fiscal capacity at supranational level for macroeconomic stabilisation in deep crises. Either we succeed in designing – at end – credible and coordinated countercyclical rules for national fiscal policies, or we should think about some 4/5  BIS central bankers' speeches  central fiscal capacity, reversible in its use, controllable in its size, but effective through the cycle. This should be one area of discussion in the “European momentum” which the crisis has initiated. Thank you for your attention.
