BERLIN — The European Central Bank’s (ECB) decision in September to pursue more monetary-policy easing was controversial, with one board representative, from Germany, resigning over the move. But one of the most remarkable features of the ECB’s position has not gotten enough attention: the admission that inflation expectations have become de-anchored, and that without fiscal-policy support, the central bank will probably fail to fulfill its price-stability mandate for the foreseeable future.
In fact, many observers, and even several members of the ECB’s governing council, now argue that the bank needs to adapt its mandate with a new definition of price stability in mind. They are right, but there is one crucial caveat.
Since central-bank independence was strengthened in the 1990s, it has become clear that, in normal times, the specific mandate does not matter much. The United States Federal Reserve managed to guide expectations and achieve price stability with its dual mandate, price stability and maximum employment, just as well as the Bank of England or the ECB, with their narrower price-stability mandates.
After the global financial crisis, however, the traditional mandate proved inadequate to cope with large-scale financial instability, fickle market confidence and political paralysis. Developed-country central banks had to devise policies on the fly, without a guiding framework. Each in its own way pursued unprecedented monetary easing, massively expanding its balance sheet, in order to provide much-needed support to the economy.
In many ways, these measures succeeded: Monetary expansion played a major role in pulling the economy back from the brink. But, over time, central banks’ capacity to affect the real economy declined. Today, and for the foreseeable future, domestic inflation is increasingly affected by global, rather than local, developments, and financial (in)stability and fiscal policy are far more influential than monetary policy.
For the ECB, this generates a particularly serious challenge. After all, unlike other central banks, it must account for the preferences of 19 sovereign national governments, with little to no structural or fiscal-policy coordination. The eurozone is also highly fragmented financially, lacking a common capital market, a unifying safe asset or macroeconomic stabilisation tools.
The ECB needs a more realistic and flexible mandate. Given the eurozone’s fragmented nature, that mandate should probably still be centered on price stability. But it should also recognise that the current definition of price stability, “below, but close to, 2 per cent inflation over the medium term”, is too narrow.
A broader definition is needed, according to which the ECB pursues a symmetric inflation target of 2 per cent, within a 1.5-2.5 per cent band, over a longer time horizon. Some advocate an even higher target: For example, Olivier Blanchard, a former International Monetary Fund chief economist, has proposed re-anchoring expectations at 4 per cent. A different proposal, from New York Federal Reserve President John Williams, is to target a price level, rather than an inflation rate.
A commitment to more broadly defined price stability in the long term would give the ECB more space during times of crisis, thereby enabling it to account better for risks to financial stability and the real economy. This would help it to stabilise prices more quickly, bolstering its credibility.
By contrast, when the ECB consistently fails to meet its price-stability objective, as it has for the last five years, it loses credibility. And, indeed, the ECB has faced harsh criticism, sometimes warranted, often not, over its implementation of untested expansionary monetary policies since 2008, partly because the measures were often poorly understood by the public. The loss of credibility has undermined the ECB’s capacity to fulfill its objectives, creating a vicious circle that threatens its de facto independence.
This is why the timing of any mandate change must be chosen very carefully. If the ECB tries to move the goalpost while it is missing the shot, the short-term blow to its already diminished credibility could be serious. Given this, the ECB must work to strengthen its standing before it adjusts its mandate, including by attempting to reach the existing price-stability objective after years of failure.
At the same time, the ECB must communicate better what its capabilities are. Some have urged the ECB to try addressing the solvency problems of banks or governments during the crisis. Others would like the ECB to discipline governments to do the “right” thing and consolidate spending. A central bank must do neither and would utterly fail if it tried. But these attempts have hurt the ECB’s standing, particularly in Germany, and have diminished its credibility.
Clarifying the contents of the ECB’s policy toolbox, including sovereign-bond purchases and other non-standard measures, would go a long way toward protecting the ECB from such attacks in the future. And when the time comes to shift its objectives, the ECB must communicate the change, which, to be sure, may not need to be as big as many believe, clearly and thoroughly.
US President John F. Kennedy was right: the time to repair the roof is when the sun is shining. The ECB cannot revise its mandate until the current storm has passed. But, with water pouring in, it cannot afford to wait very long. The sooner the ECB does what is needed to restore its credibility, the sooner it can do what is needed to protect itself from future storms.

LONDON – With her recent announcement of the European Central Bank’s long-overdue strategy review, new ECB President Christine Lagarde has generated high expectations. The review’s outcome will be the first important signal of how Lagarde intends to lead the institution – and of how the ECB is likely to address persistently low inflation in the eurozone.
The world is very different than it was in 2003, when the ECB’s strategy was last revised, and the institution has itself undergone deep changes since the 2008 financial crisis. Faced with a global recession and then the 2011-2012 eurozone debt crisis, the ECB abandoned the traditional approach of passively meeting banks’ demand for liquidity – its initial response to the financial crisis. Instead, the ECB started actively managing its balance sheet in order both to ease monetary policy and stabilize the financial system.
Furthermore, the ECB has radically expanded its operational tools. In 2014, it introduced negative interest rates on banks’ deposits with national central banks, and began providing the market with “forward guidance” concerning its future policies. And, since 2015, the ECB has engaged in asset purchases (known as quantitative easing, or QE), causing its balance sheet to double compared to 2008. Finally, the ECB has assumed larger prudential supervisory responsibilities vis-à-vis European banks under the Single Supervisory Mechanism.
The first phase of the ECB review will be narrow, focusing on defining the bank’s inflation target, the role of monetary aggregates as signals of medium- to long-term inflation, and communication. This is expected to be concluded in the first half of 2020, to be followed by a second phase of reflection.
Any meaningful review of these issues must objectively and critically analyze the decade since the financial crisis, during which average eurozone inflation has been well below the ECB’s objective of “below, but close to, 2%,” and also lower than in the United States and the United Kingdom. In particular, the review should quantify the costs of tolerating a systematically below-target level of inflation, relative to pursuing other policy options.
There are at least three hypotheses to explain the ECB’s inability to achieve its inflation objective. The “policy mistakes” hypothesis maintains that the ECB should have implemented more aggressive policies – in particular, QE – between 2012 and 2014. If these “mistakes” stemmed from an ill-defined ECB strategy, then its strategy will have to be adjusted; if they were the result of political constraints, then its decision-making process should be changed.
The second explanation highlights the inadequate coordination of fiscal, financial, and monetary policy in the eurozone. In 2009, for example, monetary easing was accompanied by a delayed cleanup of the banking sector and fiscal austerity, leading to a second recession that the ECB was late to identify. And in 2012-2014, a neutral fiscal stance was coupled with both insufficient monetary stimulus and banking-sector deleveraging.
Both hypotheses suggest that the ECB would have fared better had it clearly committed to a symmetric quantitative target for inflation or nominal GDP. That would have implied, for example, not increasing interest rates in 2011 (as the ECB did) in response to the temporary inflationary effect of higher oil prices. It also would have implied starting asset purchases in 2012 instead of 2015, and not stopping them in 2018.
The third hypothesis, favored by some central bankers, is that persistently low eurozone inflation reflects structural factors such as adverse demographics, low growth expectations, and the associated increase in demand for safe assets. This explanation thus draws parallels between the eurozone and Japan, where aggressive monetary and fiscal policies since 2013 have failed to lift the economy out of its two-decade-long slough of low inflation.
Advocates of the structural view argue that it would be better for the ECB’s policymakers to adopt a lower inflation target rather than try to engineer a monetary stimulus that ends up inflating asset prices and jeopardizing financial stability. After all, their argument implies, there is little evidence that stable low inflation is bad for welfare.
But this third hypothesis can lead to two alternative policy recommendations. The first is a “do-nothing” approach, coupled with a downward adjustment of the ECB’s inflation target in line with actual inflation. Such a course of action is justified if policymakers assume that potential output growth in the eurozone has declined independently of past fiscal and monetary stabilization policies. The second option, as under the first two hypotheses, is to maintain an accommodative monetary policy, possibly in coordination with fiscal policy. This would be the right thing to do if policymakers believed that persistent slack in the real economy would end up affecting potential output.
Most analyses imply that ECB policy has in general been too cautious during the last decade. Moreover, even if one accepts the structural explanation for trend inflation and takes the view that inflation expectations have fallen independently of past policies, the “do-nothing” option is likely to cause expectations to spiral further downward, possibly leading to a deflationary trap. One then has to consider the costs linked both to the associated relative price adjustments and to the effect that the resulting upward pressure on the real interest rate would have on the burden of private and public debt. These costs are likely to be greater than those associated with the financial-stability risk of doing “too much,” which in any case can be addressed using prudential tools.
The ECB’s new strategy will have to be based on the kind of quantitative analysis needed to answer these questions. But it also must recognize that economists are still a long way from understanding the dynamics of low inflation. Given this uncertainty, the ECB should aim to adopt robust policies that cause the least damage under a broad range of scenarios.
