Monitoring the ECB
Not just unproven, but also unsafe?

As one of the world’s key central banks, the European Central Bank (ECB) is destined to become a formidable institution both in Europe and in the wider international financial system. With the Bank taking up its policy responsibilities in January 1999 and, in so doing, confronting unexplored territory and facing a host of important, but unresolved policy issues, CEPR made provision for regular examination of the ECB’s policies from an independent, pan-European perspective. This will be done via twice-yearly reports in a Monitoring the European Central Bank (MECB) series. The reports, which will be written by economists known internationally for their work on macroeconomics and monetary policy, will fill a major gap in the scrutiny of the ECB: although the ECB exists for all EMU countries, it ‘belongs’ to no particular member state, and is accountable only to the European Parliament, which has no tradition of oversight of monetary policy.

The inaugural MECB report was published in October 1998. Entitled The ECB: Safe at any Speed?, the report was written by David Begg (Birkbeck College, London, and CEPR), Paul De Grauwe (Katholieke Universiteit Leuven and CEPR), Francesco Giavazzi (Università Bocconi, Milan, and CEPR), Harald Uhlig (CenTER, Tilburg University, and CEPR) and Charles Wyplosz (Graduate Institute of International Studies, Geneva, and CEPR). The authors argue that the ECB is not yet fully prepared to meet its responsibilities and challenges and that many operational issues remain to be settled. Even in a benign global climate, these shortcomings could prove problematical; a deteriorating climate could well expose the flaws in the design of the institution and undermine its ability to manage a major financial crisis.

The report notes that the design strategy for the ECB intentionally sought to emphasize its similarities to the Bundesbank. Despite a decade of planning for EMU, however, many crucial decisions have been left unresolved; and among the decisions actually made, a number contained compromises that have weakened the Bank from the outset. Five basic difficulties exist. First, much of the relationship between the ECB and the European System of Central Banks has been left unclear. With the existing central bank governors remaining in charge of their own national institutions, but simultaneously controlling the ECB Council, national perspectives are likely to persist and lines of authority to remain ambiguous. Second, the monetary-policy strategy also has been left (deliberately) ambiguous, which means that the transparency necessary for accountability will be difficult to accomplish. Third, the process by which monetary policy will be conducted – whether via money-stock or inflation targets – has still to be determined. Fourth, who is to speak for the ‘EuroXI’ in global institutions (such as the G-7) in which both fiscal- and monetary-policy coordination issues may arise both within Euroland and between Euroland and other major actors? And fifth, like any central bank, the ECB will have substantial discretionary powers – for example, in its regulatory and its lender-of-last-resort roles. Yet the basis on which discretion will be exercised is unclear.

In short, as with most previous moves to integrate European markets, and contrary to the ECB’s own expressed beliefs, the monetary integration process has led to weak central institutions reflecting national disagreements and political compromise. In the authors’ view, its flawed and incomplete design leaves the ECB both weak and unprepared, especially where the flaws and incompleteness are symptomatic of deeper disagreements. They therefore urge that steps be taken to strengthen the ECB in relation to national central banks, whose governors will otherwise retain too much power, inhibiting development of a truly European perspective. Ideally, there should be more centralized operating procedures, and the balance of voting power between the ECB’s executive board and the national central bank governors should be tilted in favour of the former.

The report acknowledges that such changes cannot happen immediately. None the less, without them, there is a danger that the ECB will simply repeat the mistakes made by the early Federal Reserve as a result of its (the Fed’s) decentralized and disputed authority. Two early practical steps could mitigate some of the danger. First, the resources available to the ECB should be increased, so that it can develop its own research and other support services in healthy competition with its national counterparts; and second, a number of national central bank governors should relocate to Frankfurt rather than continue to be based in their national institutions.

Turning to the monetary policy issue, the authors argue that in seeking to prove its mettle, the ECB will do itself no favours if it embarks on its role in ‘foggy’ conditions. On the contrary, the Bank would benefit from helping its many constituencies to watch and appraise its conduct. In this respect, the report seeks first to debunk the myth that central banks do care (or should care) about price stability to the exclusion of all other goals. There is ample evidence that, in practice and on average, most central banks follow a ‘Taylor rule’, in terms of which interest rates are changed whenever either inflation or output depart from set targets. Ex post, it is clear that not even the Bundesbank has assigned a zero weight to the output gap. There is thus no need for the ECB to display total stubbornness in relation to price stability in order to establish its reputation.

Furthermore, because monetary policy affects prices with a long lag, there is considerable latitude in interpreting a mandate to pursue price stability. For the same reason, the ECB cannot be held instantly accountable for inflation. Consequently, it will have some discretion about how quickly to achieve inflation targets. On the assumption that the ECB inevitably will end up behaving like other responsible central banks, economists will, in due course, uncover from the data its average behaviour. In the interim, the ECB will gain nothing from seeking to hide its normal behaviour.

The Bank should therefore adopt and announce the rule that it intends will govern its normal behaviour towards interest rates when inflation and output deviate from their target or trend paths. This would have three advantages: it would help ensure systematic and consistent internal decision-making; it would act as an important external communication device; and it would act as a commitment device in the Bank’s strategic interaction with both fiscal authorities and wage setters in the EuroXI. The authors reject, as ‘unconvincing’, the three arguments that have been advanced to justify reluctance to announce a policy rule, namely that secrecy offers scope for ‘creative ambiguity’; that, since the launch of the euro represents a ‘break in history’ and a change in the policy environment, the consequent structural uncertainty will render it more difficult for markets to extract information signals from the Bank’s actions; and that the world is ‘too complex’ for simple rules. Nor would there be any danger that, in announcing the rule, the ECB would be limiting its capacity to exercise discretionary powers in response to specific and temporary circumstances that warrant departing from the rule. The public would expect no less, just as it would expect the ECB to avoid capricious or erratic behaviour.

Announcement of a rule would thus provide a benchmark against which to check that discretion had no hidden systematic components. Since policy takes time to work, however, announcement would also involve making public the ECB’s forecast inflation and output growth rates for Euroland, which would indicate in turn the expected deviations of these variables from their targets. But the report also suggests that, on the basis of the published forecasts, the ECB should go one step further and explain what its normal rule would then imply for interest rates, and whether or not it considered that any deviation from this normal reaction was required.

In essence, the report contends that there is no serious conflict between transparency and effectiveness. On the contrary, transparency would assist markets, and improve both the ECB’s accountability and the quality of its decision-making. Changes in interest rates should be accompanied by a public explanation of why rates were changed, including any evolution in the forecasts of economic conditions. Votes cast by individual members of the Governing Council should be made public after a short time. On the question of the policy rule itself, the report comes down firmly in favour of an inflation-rate, rather than a money-stock growth-rate target. Whatever the chosen target, however, the imperative of communicating the strategy to the public remains.

The report also deals at some length with some of the more specific challenges that will face the ECB in its first year under two alternative scenarios: (1) if the economic climate in Europe remains relatively benign; and (2) if the global environment deteriorates significantly. The authors note first that the ECB will face two problems not encountered by the US Fed: labour markets are more rigid, potentially giving rise to more persistent recessions; and fiscal policy is in the hands of 11 uncoordinated authorities, giving rise to potential free riding by each fiscal authority. The ECB should strive to avoid hard landings, but it cannot succeed if any monetary tightening becomes the excuse for fiscal expansion by individual member states. Since politicians care even more about recession than the ECB, labour-market rigidities may actually enhance the Bank’s threat to create recession if fiscal discipline breaks down. It may be possible to sustain some cooperation between fiscal and monetary authorities. The EuroXI committee would then play a key role in coordinating fiscal policies among EMU members.

Second, there is no guarantee that the expensive TARGET payments system will actually be used for large-value transactions. Alternative private settlement systems will be vulnerable in a crisis, however, and may force the ECB to act as lender of last resort. More generally, financial regulation within EMU is at present unsafe. No secure mechanism exists for creating liquidity in a crisis, and there remain flaws in proposals for dealing with insolvency during a large banking collapse. Asymmetric national exposure to risky foreign loans may lead to conflicts about the appropriate response. In the longer run, centralization of regulation is essential.

Third, a global crisis would set off the deflation already evident in Japan. Although deflation is a symptom of deeper causes, such as failures in bank regulation, it is also damaging in its own right since it escalates the real burden of debt repayment. It is therefore important that the ECB should pay as much attention to avoiding undershoots of its target inflation range as it pays to avoiding overshoots.
