By David Barwick – FRANKFURT (Econostream) – The European Central Bank’s quiet period is intended to steady market expectations about monetary policy decisions by prohibiting communication in the seven days before a Governing Council meeting. In the current environment, it has the opposite effect, and that is just one of its drawbacks.

The ECB’s official justification for the quiet period, as its website explains, is predicated on the view that “markets are extremely sensitive” in the run-up to policy meetings, and that banning comments can “help prevent excessive market volatility or unnecessary speculation.” The problem is that when information arrives continuously and markets are actively repricing risk, enforced silence is less a remedy for uncertainty than an additional source of it.

The timing of ECB silence is increasingly misaligned with the timing of new information. The current blackout offers an excellent example, as markets have had to process a constant flow of developments bearing directly on the inflation outlook and the policy reaction function. Yet precisely those best placed to interpret the developments—the policymakers themselves—are officially unable to speak.

The bizarre idea that in the absence of official communication markets would sit tight and ignore relevant developments illustrates the structural tension at the heart of the ECB’s framework: policy is data-dependent and decided meeting by meeting, but the quiet period prevents the ECB from acknowledging in real time when incoming information shifts the balance of risks.

Ultimately, the self-imposed silence can actually narrow rather than preserve optionality. If events during the blackout materially alter the policy calculus, the ECB is left with the choice of either surprising markets by contradicting its own earlier guidance, or validating expectations with a decision that no longer fully reflects the information set. What is presented as a safeguard thus risks becoming a constraint on flexibility.

Predictably, in the absence of authoritative guidance, pricing reflects not what policymakers have said, but what markets believe policymakers must now be thinking. The ECB leaves unexplained why this weaker, more volatile anchor for expectations is preferable.

Nor is the quiet period necessarily all that quiet: the prohibition is observed selectively, with ECB President Christine Lagarde herself a serial offender. For example, on October 25, 2023, one day (!) before an interest rate decision, she gave an interview to Greek television channel Antenna TV in which she expounded at length on policy-relevant subjects (ironically, at the evening’s official dinner of the Bank of Greece, the host of that Governing Council meeting, she prefaced her speech by declaring with a straight face that “as we are in our so-called ‘quiet period’ – I will not be making any remarks on current or future monetary policy”).

Similarly, at the World Economic Forum six days before the Governing Council meeting of January 30, 2025, Lagarde made various policy-relevant comments during a panel discussion, including the profession of “strong confidence that [inflation] is going down rather than up.”

Silence has not reigned throughout the current quiet period, either, with National Bank of Slovakia Governor Peter Kažimír addressing monetary policy fairly directly last Thursday. In contrast, the speech given Monday by Bank of Greece Governor Yannis Stournaras passed muster; the closest it came to the boundary was his observation that Greece’s “outlook remains positive, despite strong external shocks and elevated uncertainty.”

However, the same defense cannot be made of a third Governing Council member, who spoke at considerable length on monetary policy before some 40 people during the current quiet period—technically a clear violation, even if the only news medium present made the strategic choice not to report on the event.

None of this means the quiet period lacks a rationale. In a calmer world, limiting last-minute signaling can help prevent unnecessary volatility. But the ECB no longer operates in a setting where the main risk is excessive communication in the final days before a meeting. The more pressing risk is that silence deprives markets of clarity precisely when clarity is most needed.

The question, then, is not whether the ECB should fill all the silence with talk. It is whether it should be prevented from communicating when the information set is still evolving. A framework built on continuous assessment is inconsistent with a rule that enforces discrete silence, and woefully inadequate for the current environment.
