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”. Public debt is of a somewhat different nature: we do not know if nor when the tragedy – a major confidence shock, for instance – may happen. But we know for sure that rising public debt is a growing risk hanging over us, and still more over our children and grandchildren. Let us therefore call it a “tragedy on the horizon”: a moving horizon – indeed nobody knows precisely where geographically the horizon lies –, but it will not be any less threatening. So what would our best response to this possible tragedy on the horizon be? And what can we do to avoid it? Let me elaborate somewhat on a simple triptych (i) Monetary Policy, (ii) Fiscal Policy and (iii) their renewed interactions.
We rightly decided to keep a steady hand in the last Governing Council meeting, and I still think today that our present very accommodative monetary stance is appropriate. But steady hands are not tied hands: we have free hands for the future, and will be ready to act further if needed.
Let me now turn to the ECB’s strategic review, on which work has restarted. It is more extensive than the FOMC’s as it will cover, among many things, structural changes: climate change, financial stability; and the effects of digitalisation. The Eurosystem will take its time, as the Fed did, to consider the different alternatives. But we can already today shed some light on three key points, especially after the excellent “ECB Watchers” conference in Frankfurt on 30 September:
1/ Our mandate puts a clear priority on price stability, and is not a dual mandate. But neither is it merely a single one: I would characterise it as a two-tiered mandate that includes at least two other objectives without prejudice to price stability: on the one hand “to support the general economic policies in the Union” contributing among other aims to a “social market economy, aiming at full employment and social progress”2; and on the other hand “to safeguard the stability of the financial system”3.
Furthermore, I would argue that there is still less of a difference between a dual mandate and flexible inflation targeting in the present economic context: notably, the measures we have taken to offset the effects on inflation of negative shocks such as the global financial crisis or the health crisis have a direct effect on growth and employment.
2/ Average inflation targeting is a flexible tactic, possibly temporary, within a wider strategy of keeping inflation sustainably where expected. But still more importantly, our inflation objective has to be symmetric and medium-term.
If credibly symmetric and medium-term, our inflation objective would probably achieve similar outcomes ex post than explicit average inflation targeting.
3/ Finally, we need to rethink our “second pillar” – the present monetary analysis – notably in light of financial stability concerns. To do so, we could track a broader set of nominal aggregates:
Of course we should not repeat the mistakes of the last crisis, and tighten, the fiscal taps too quickly. But in the longer term, fiscal discipline is also needed. In the current context of an unprecedented rise in public debt, some tempting illusions have arisen. We must not give into them. We cannot, for instance, allow ourselves to believe that cancelling the public debt held by the central bank is a viable solution. Nor is the softer version of this idea – converting this debt into perpetual bonds.
Let us be clear on this: the public debt pile – which has risen sharply – will need to be paid back eventually… To do so, three combined levers will have to support the necessary debt reduction strategy:
1/ We will first need time in order not to phase out fiscal accommodation too early, and create cliff effects like in 2011-12. We should resume the debt-ratio reduction after growth returns to its pre-crisis level probably around 2022. But fiscal policy cannot simply be countercyclical in bad times; the same thinking needs to be applied in better times as well.
2/ Growth is indeed a key determinant in financing the debt inherited from the crisis. This leads me to the debate initiated early last year by O. Blanchard. First, the best way to ensure that the differential between the interest rate and the growth rate (r-g) remains negative – which is not granted forever, nor everywhere – is to increase g. And hence, let us listen to the balanced message of Blanchard: “public debt is bad, but not catastrophic. It can be used, but it should be used right.” Unfortunately, the quality and the content of public spending is too often the “blind spot” in the fiscal debate. In August, M. Draghi quietly coined the telling expression of “good debt”. Expenditure should be used for productive purposes and for young people: education and training, and research, which have a strong impact on long-term growth. On the contrary, fiscal transfers have a much weaker multiplier in the long run.
3/ Better control of public spending: unfortunately, in many countries including the one I know best, we have not managed to keep spending under control. Covid-19 related public spending is clearly the buffer mechanism that the economy needs in the current circumstances. But there are also less warranted expenditures and this is precisely what we must focus on since the pace of extra-covid spending seems in several countries to be accelerating even more quickly than before the virus crisis.
Broadly speaking, the recipe for debt reduction depends on each country’s “own speciality”: some countries need above all to boost productivity growth; others need to control their public spending but they have one ingredient in common: efficient reforms. Let us not forget this imperative of reforms in the short-term urgency of the covid-crisis.
In the current context, both monetary and fiscal expansions are indispensable to sustain demand and inflation and to mitigate the costs of the current crisis. However, given the unprecedented rise in public debt and extremely low or negative interest rates, some are tempted by the seductive lure of “fiscal dominance”, a situation in which the central bank would have to follow another objective: the financing of public debt. This paradigm shift could jeopardize our independence and our mandate. Ultimately, it could lead to a loss of confidence in the value of the money, as observed in the past.
In revisiting the interaction between monetary and fiscal policies, there is a need to make a clear distinction between short-run opportunities, corresponding to the current crisis period, and medium-term challenges, which will arise when the economy has fully recovered. In addition, in the euro area, having a single monetary authority and 19 national fiscal authorities creates further challenges in the absence of coordination among Member States on their budgets and of a permanent euro area fiscal capacity. This is why risk-sharing across the euro area should not rely only on fiscal mechanisms but also on private markets by completing the Capital Markets Union.
In the short term, the risk of fiscal dominance is not an issue. Today, monetary and fiscal objectives are fully aligned and require expansionary policies from both sides. Fiscal policy can help monetary policy to achieve ist inflation objective by boosting demand. Firms and households are encouraged to borrow in such an environment, which allows them to benefit fully from the monetary stimulus. Monetary policy can also render fiscal policy more effective. The dominant view is indeed that fiscal policy becomes more effective at the Effective Lower Bound (ELB) because monetary policy is less likely to react to offset its effects. This is because either the desired policy rate is sufficiently below the ELB or the central bank has committed to keep interest rates unchanged through forward guidance.
However, conflicts of objectives between fiscal and monetary policies may arise in the future. The ongoing accumulation of public debt and the large expansion of central banks’ balance sheets increase the likelihood of such conflicts. On the one hand, large fiscal stimuli for too long may lead to concerns about debt sustainability and, via the expectation of future fiscal tightening, offsetting the favorable effects on output and inflation. On the other hand, central banks should keep the risks taken in their balance sheets under control to avoid threatening their own independence. Indeed, low inflation today is not a guarantee that it will remain low forever. They must keep a sound balance sheet with adequate capital in order to keep full control of their monetary stance all along the road.
The key question is then how to reconcile the benefits of a mutual reinforcement of monetary policy and fiscal policy in the short-term with the challenges of keeping inflation under control and public debt to sustainable levels in the longterm. There is no magic answer to this question but I will try to sketch here some basic principles that are in my opinion ingredients of a sound policy-mix recipe:
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 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.
