ECB June Hike Expected as Stagflation Risk Clouds Outlook

A Reuters poll of economists shows a majority expect the European Central Bank to raise its deposit rate by 25 basis points to 3.50% at the June meeting. The expectation holds even as the eurozone economy faces a rising stagflation risk – weak growth paired with persistent inflation.

The simple interpretation is that the ECB prioritizes inflation control over growth concerns. Headline inflation remains well above the 2% target, and core inflation has proven stickier than expected. The poll suggests economists see the ECB unwilling to pause until there is clearer evidence that price pressures are durably easing.

The fuller market read involves the transmission through rates, the euro, and risk appetite. A June hike would push the ECB deposit rate to its highest level since 2001. That would widen the rate differential with the Federal Reserve if the Fed pauses or cuts later this year. The differential supports the euro against the dollar in the near term, particularly if the ECB signals further tightening beyond June. The stagflation backdrop, however, complicates the outlook. Weaker growth reduces the terminal rate the ECB can reach. Any signs that the economy is deteriorating faster than expected could cap euro gains.

The Stagflation Trade-Off for the ECB

The poll highlights that economists view stagflation as a key risk. The eurozone economy barely grew in the first quarter. Forward-looking indicators point to further weakness: manufacturing output is contracting, and services activity is slowing. At the same time, inflation runs at 7.0% headline and 5.6% core, well above the ECB's target.

For the ECB, this creates a difficult trade-off. Raising rates into a weakening economy risks deepening the downturn. Pausing too early could entrench inflation expectations. The poll suggests that economists expect the ECB to err on the side of tightening, at least for June. The key question is whether the ECB will signal a pause after June or keep the door open for further hikes.

The risk of stagflation also raises questions about peripheral bond spreads. Italian BTPs could come under pressure if growth slows faster. The ECB's tightening limits the room for fiscal expansion. That would test the Transmission Protection Instrument (TPI) framework designed to prevent unwarranted spread widening.

Near-Term Path for EUR/USD and Bund Yields

A June hike would likely push EUR/USD higher in the short term. The rate differential shifts in favor of the euro. The pair has been range-bound between 1.08 and 1.10. A hawkish ECB could break it higher. The upside may be limited if the ECB's growth forecasts are downgraded alongside the rate decision. The euro's upside against the dollar also depends on the Fed path. If US data continues to show resilience, the Fed may keep rates higher for longer, limiting EUR/USD gains from the ECB hike. For more on the pair's dynamics, see the EUR/USD profile.

On the bond side, German bund yields would rise on the hike. The 10-year yield could test the 2.50% level. The yield curve could flatten further. Short-term rates rise on the hike while long-term rates are capped by growth concerns. That flattening is a classic signal of stagflation expectations.

Next Decision Point

The next concrete catalyst is the ECB's June 15 meeting. The rate decision and updated staff projections will be released. The projections will show whether the ECB expects inflation to return to target by 2025. They will also show whether growth forecasts have been cut. If the projections show a deeper growth downgrade, the euro could give back its initial gains. If inflation forecasts are revised up, the ECB may signal more hikes, supporting the euro further.

For traders, the key level to watch on EUR/USD is 1.10. A break above that level on a hawkish ECB would open the door to 1.12. A failure to hold 1.08 would suggest that the stagflation risk is dominating the rate differential story.
