Why central banks will just keep getting weaker

Mario I. Blejer, former governor of the Central Bank of Argentina, on independence.

The global financial crisis has raised fundamental questions regarding central banks’ mandates. Over the past few decades, most central banks have focused on price stability as their single and overriding objective. This focus supported the ascendancy of “inflation-targeting” as the favoured monetary policy framework and, in turn, led to operational independence for central banks. The policy was a success: the discipline imposed by strict and rigorous concentration on a sole objective enabled policymakers to control – and then conquer – inflation.

But, as a consequence of this narrow approach, policymakers disregarded the formation of asset- and commodity-price bubbles, and overlooked the resulting banking-sector instability. This, by itself, calls for a review of the overall efficacy of inflation-targeting. Moreover, after the financial crisis erupted, central banks were increasingly compelled to depart from inflation targeting, and to implement myriad unconventional monetary policies in order to ameliorate the consequences of the crash and facilitate economic recovery.

With advanced economies struggling to avoid financial collapse, escape recession, reduce unemployment, and restore growth, central banks are being called upon to address, sometimes simultaneously, growing imbalances. This has triggered a search for a radical redefinition of central banks’ objectives – and has cast doubt on the appropriateness of maintaining their independence.

In particular, central banks’ behavior during the crisis has called into question whether inflation-targeting is an effective framework in the presence of systemic shocks, and, more broadly, whether it can be sustained throughout economic cycles. After all, a policy regime that sets aside its only goal during a crisis seems to lack the ability to cope with unexpected challenges. Critics identify this “crisis straitjacket syndrome” as the main problem with single-minded inflation targeting.

While theoretical arguments can be made to justify recent departures from policy, the reality is that in the post-crisis world, advanced-country central banks’ goals are no longer limited to price stability. In the United States, the Federal Reserve has essentially adopted a quantitative employment target, with nominal GDP targets and other variations under discussion in other countries. And financial stability is again a central-bank responsibility, including for the more conservative European Central Bank.

This shift toward multiple policy objectives inevitably reduces central-bank independence. Some analysts have recently claimed that this is because the pursuit of GDP growth, job creation, and financial stability, as well as the establishment of priorities when there are tradeoffs, clearly requires political decisions, which should not be made by unelected officials alone. Moreover, by pushing interest rates toward zero, the current policy of quantitative easing (increasing money supply by buying government securities) has strong, often regressive, income effects. Opponents of central-bank independence contend that, given the allocational and distributional consequences of current monetary-policy interventions, central banks’ decision-making should be subject to political control.

But this argument neglects an important point. While it is true that multiple policy targets tend to increase the political sensitivity of central banks’ decisions, concentrating only on price stability also has important distributional consequences and political implications. In fact, politicisation is a matter of scale, not a substantive transformation of monetary policymaking.

The real reason why central-bank independence tends to create a democratic deficit under a multi-target monetary-policy regime, and why it has become increasingly vulnerable, is that the two main arguments in favor of it no longer apply.

The first argument in favor of central-bank independence is that, without it, politicians can exploit expansionary monetary policy’s positive short-run effects at election time, without regard for its long-run inflationary consequences. (By contrast, fiscal and exchange-rate policies rarely imply comparable temporal trade-offs, and thus are difficult to exploit for political gain.) But this argument becomes irrelevant when ensuring price stability is no longer monetary policymakers’ sole task.

The second argument for institutional independence is that central banks have a clear comparative advantage in dealing with monetary issues, and can therefore be trusted to pursue their targets independently. But this advantage does not extend to other policy areas.

Given that central banks are likely to continue to pursue multiple objectives for a long time, their independence will continue to erode. As long as governments do not encroach excessively on central-bank decision-making, this development will restore balance in policymaking and support policy coordination, particularly in times of stress.

Voters are turning against Brexit but the Lib Dems aren't benefiting

Labour's pro-Brexit stance is not preventing it from winning the support of Remainers. Will that change?

More than a year after the UK voted for Brexit, there has been little sign of buyer's remorse. The public, including around a third of Remainers, are largely of the view that the government should "get on with it".

But as real wages are squeezed (owing to the Brexit-linked inflationary spike) there are tentative signs that the mood is changing. In the event of a second referendum, an Opinium/Observer poll found, 47 per cent would vote Remain, compared to 44 per cent for Leave. Support for a repeat vote is also increasing. Forty one per cent of the public now favour a second referendum (with 48 per cent opposed), compared to 33 per cent last December. 

The Liberal Democrats have made halting Brexit their raison d'être. But as public opinion turns, there is no sign they are benefiting. Since the election, Vince Cable's party has yet to exceed single figures in the polls, scoring a lowly 6 per cent in the Opinium survey (down from 7.4 per cent at the election). 

What accounts for this disparity? After their near-extinction in 2015, the Lib Dems remain either toxic or irrelevant to many voters. Labour, by contrast, despite its pro-Brexit stance, has hoovered up Remainers (55 per cent back Jeremy Corbyn's party). 

In some cases, this reflects voters' other priorities. Remainers are prepared to support Labour on account of the party's stances on austerity, housing and education. Corbyn, meanwhile, is a eurosceptic whose internationalism and pro-migration reputation endear him to EU supporters. Other Remainers rewarded Labour MPs who voted against Article 50, rebelling against the leadership's stance. 

But the trend also partly reflects ignorance. By saying little on the subject of Brexit, Corbyn and Labour allowed Remainers to assume the best. Though there is little evidence that voters will abandon Corbyn over his EU stance, the potential exists.

For this reason, the proposal of a new party will continue to recur. By challenging Labour over Brexit, without the toxicity of Lib Dems, it would sharpen the choice before voters. Though it would not win an election, a new party could force Corbyn to soften his stance on Brexit or to offer a second referendum (mirroring Ukip's effect on the Conservatives).

The greatest problem for the project is that it lacks support where it counts: among MPs. For reasons of tribalism and strategy, there is no emergent "Gang of Four" ready to helm a new party. In the absence of a new convulsion, the UK may turn against Brexit without the anti-Brexiteers benefiting.
