April hold, June live: uncertainty is now the ECB’s main policy driver My read: the ECB does not look confused. It looks like a central bank pricing the option value of waiting while the shock itself is still being written in real time. Markets are leaning toward no move on April 29-30, but roughly a full 25bp is still priced by June. That is not a contradiction. It is the market admitting that the April meeting may arrive before the evidence does, while June may arrive after enough transmission has shown up to matter. Nagel’s “opaque, cloudy” line is the tell. When a policymaker says data is arriving daily in the form of news, he is saying the relevant input is no longer just scheduled releases; it is every Hormuz headline, every oil swing, every sign that an energy shock is either fading or crawling into broader pricing behaviour. Why the ECB is waiting The March stance was clear: keep the deposit rate at 2.0%, stay data-dependent, stay meeting-by-meeting, and do not pre-commit. That is what a central bank does when the distribution matters more than the point forecast. March inflation did jump to 2.6% from 1.9%, largely on energy. But an energy pop is not the same as durable second-round inflation, which is why an April hold makes sense even with June still live. The real risk Kazaks’s “layer cake of shocks” is the right frame. Stacked shocks are where linear forecasts break: oil becomes transport, transport becomes food and industrial costs, and then the real question becomes whether firms and labour start to internalise a new inflation regime. That is also why Lagarde’s late-March line matters. Even a temporary overshoot can justify a measured response if doing nothing makes the reaction function look unserious. Optionality is not dovish; it is a way to keep credibility without getting boxed into a path. Bottom line: the ECB’s new reality is not confusion but policy under radical uncertainty. In this setup, waiting is not weakness. It is the strategy that preserves the ability to move fast once the fog turns into signal.
