A highly regarded doctor assumes the care of a chronically impaired patient who is growing weaker and more vulnerable. The patient’s longstanding treatment is not only becoming less effective; now it is also introducing harmful side effects. A better approach exists, but it is not available at the new doctor’s hospital. And in the facilities where it is available, the doctors are too distracted to take on the case.

The new doctor is Christine Lagarde, the widely admired former managing director of the International Monetary Fund who will soon succeed Mario Draghi as president of the European Central Bank (ECB). Her challenge will be to avoid a second lost decade of low, insufficiently inclusive eurozone growth. How the patient fares under her care – and whether she can get key eurozone governments to provide the necessary treatment – will define not just her own legacy, but also that of Draghi.

There is now little doubt that the European economy is losing momentum. The earlier, overly optimistic prognosis of a sustained growth pickup has finally given way to the grim reality that both structural and cyclical headwinds are bearing down on economic activity. The previous consensus growth forecast of around 2% for 2019 is now converging on around 1%; it could well go even lower.

Relying on just one response: unconventional monetary policy

Still to come is a broader realization that Europe is at risk of suffering what economists call «stall-speed growth.» Under such conditions, growth may remain positive, but it will be insufficient to accommodate the demands of other forces: pockets of excessive indebtedness, rising demand for social services, the need for better infrastructure, and deepening popular anger, political polarization, and alienation.

Moreover, previously unthinkable conditions that could undermine the very integrity of a market system will suddenly become possible – even likely. Negative interest rates in Europe, for example, do not look likely to be reversed any time soon. Worse, in what is already a structurally impaired economy, Europeans have yet to deal fully with the detrimental impact of global trade tensions, which have hit export-dependent industries in Germany – the region’s powerhouse – especially hard.

Despite all of these negative developments, European authorities continue to rely on just one response: unconventional monetary policy involving negative interest rates and large-scale purchases of securities (quantitative easing, or QE). To be sure, this approach was effective in containing a debt crisis that was threatening both the monetary union and the single currency earlier in the decade. But it has proven increasingly ineffective in promoting sustainable economic growth.

Negative interest rates have side effects

Concerns over the ECB’s protracted reliance on the same old medicine have been increasing, even within the ECB, owing to a growing awareness of the detrimental effects of negative interest rates. Negative rates can curtail the provision of long-term financial-protection services (such as life insurance and retirement products) to European households, thereby undermining economic security. They encourage excessive risk-taking, which can lead to financial instability down the road. And they promote an inefficient allocation of resources across the broader economy.

To the extent that these risks are real and mounting (which I believe they are), the ECB will find it increasingly difficult to continue pursuing the same policy in the face of growing complaints and political pressure. But it cannot simply stand still, given the deterioration in the European economy. And it can scarcely even consider the option of unwinding the unconventional policies of the past decade, as that would raise the risk of immediate economic and financial disruptions.

The ECB’s lose-lose-lose trilemma can be resolved only through a comprehensive pro-growth approach at both the national and regional levels, involving measures that are not available to central banks. European countries need deeper structural reforms – including infrastructure modernization and worker retooling and retraining – to boost the productivity of both capital and labor. Where possible, they should be pursuing fiscal stimulus, and resolving persistent debt overhangs that are stifling existing growth engines and impeding the emergence of new ones. And at the regional level, Europe needs to expand and improve its policy architecture, not least by completing the banking union and resolving long-standing differences over fiscal integration.

Lagarde’s got what it takes

The hope now is that Lagarde – with her exceptional mix of interpersonal skills, professional networks, and national and international policy experience – will jump-start the pivot that Europe needs. The challenge is one of political will, not engineering, and Lagarde’s recent accomplishments at the IMF – where she put a spotlight on the economic implications of gender bias and climate change – show that she is capable of ushering in the necessary changes.

This is not to downplay the scale and complexity of the challenges Draghi has faced. They are real, and they have become deeply embedded in the structure of Europe’s political economy. Still, they are not insurmountable. Lagarde brings a uniquely well-suited skillset to her new position, and she is taking the reins at precisely the right moment for Europe to make the changes needed to avoid a second lost decade. Her legacy will now be bound up with that of Draghi, whose courageous promise in 2012 to do «whatever it takes» to save the euro has since been overshadowed by the renewed threat of recession and financial instability.
