ECB Signals Easing, But What’s Left in the Policy Arsenal?

Acentral banker’s nightmare is losing control of inflation expectations. Whereas decades ago the challenge facing major central banks was reining in overly high inflation expectations – a process that ushered in central banks’ independence and inflation targets – the European Central Bank’s (ECB) challenge today is reviving unduly low expectations up toward its stated aim of “inflation rates below, but close to, 2% over the medium term.” ECB president Mario Draghi took a step in addressing this challenge at the 25 July Governing Council meeting, promising the council will act with determination at its next meeting in September.

We expect ECB easing in September – but will it be effective?

Come the fall, the ECB will likely deliver yet another easing package that could effectively deplete its monetary policy toolbox: We anticipate another small cut of the deposit facility rate to −0.50%, exempting banks’ excess reserves from the tax imposed by negative interest rates, and restarting asset purchases, including raising its self-imposed 33% issue and issuer limits on sovereign debt holdings. And to reinforce forward guidance, the easing package might include an ultra-long refinancing operation at a fixed rate to entice corporations and households to take out bank loans.

Yet as the eurozone enters its sixth year of unconventional monetary policy, is this not all pushing on a string? And if the ECB uses up what remains of its policy flexibility in the coming months, what will be the consequences the next time a recession materialises?

One lesson from Japan is that secular forces beyond the control of monetary policy can hold down inflation for long periods of time and there is little monetary policy can do to change that. Evidence suggests aging societies grow more slowly and produce less inflation, while globalisation, technological advancements, and labour market reforms that increase wage flexibility limit the pass-through of cost pressures from producers to consumers. These conditions describe the eurozone today. Even if the European Treaty mandates the ECB to take action, the efficacy of its marginal actions seems to be diminishing.
