Eurozone’s preliminary Consumer Price Index (CPI) for May has increased by 1.9% year-on-year, slightly below the expected 2.0%. This contrasts with April’s higher rate of 2.2%, showing a deceleration in inflation.
Core CPI, which excludes volatile food and energy prices, rose by 2.4% compared to the anticipated 2.5%, down from the previous 2.7%. These figures suggest easing inflation pressures, potentially paving the way for the European Central Bank to consider a rate cut in their upcoming meeting.
Cooling Inflation Measures
What we’re seeing here is a continued cooling in both headline and core inflation measures across the euro area, with May’s flash estimate confirming a drop from the prior month. Headline CPI moderated to 1.9% year-on-year—just a tenth below forecasts, but enough to build a narrative that pressures on consumer prices may be retreating more rapidly than suspected. Core inflation, often preferred by policymakers due to its filtering of more erratic components like food and energy, also eased further than expected. That decline from April’s 2.7% to May’s 2.4% gives a clearer picture: pricing dynamics beneath the surface are softening.
Traders should take note. If we interpret the divergence between expectation and release not in isolation but as part of a broader trend, we’re seeing an incremental shift in the baseline assumptions for monetary policy. The European Central Bank has now further validation to press forward with a slightly more accommodative stance. Prior to this, markets had already started pricing in the possibility of a cut, but this data adds an extra layer of confidence—especially if wage growth and services inflation show restraint in upcoming datasets.
From the perspective of positioning, shorter-term rates are already adjusting towards this possibility, with swaps markets beginning to reflect a stronger probability of an initial move in the next meeting window. German bunds and front-end sovereign spreads have started to respond accordingly, with tighter ranges and lower yields permeating the 2Y to 5Y sector.
Future Outlook
Looking ahead, attention might tilt towards service cost disinflation and monthly wage negotiation cycles across core member states such as Germany and France. If unit labour costs stabilise or retreat, that could further bring forward rate cut expectations. For us, it would make little sense to bet against softening policy if that trajectory continues. That said, the ECB remains sensitive to external shocks and geopolitical disruptions, so while the inflation side of the mandate appears to be softening, vigilance remains.
No need, at this stage, to adjust implied volatility substantially, but gamma positioning could see renewed interest depending on headline remarks from ECB members leading up to the decision. If Lagarde and her colleagues begin to pivot their rhetoric from a wait-and-see tone towards coming action, the curve could witness another twist.
We also recognise that the momentum in EUR-denominated rates trading has been driven more by macro prints versus central bank commentary of late. That pattern may hold in the near term, though liquidity over the summer period could distort flow-driven signals.
As for hedging strategies, there’s room to rotate out of higher convexity shorts and into spreads that reward a flattening euro curve. Those who are still holding onto April pricing assumptions might find themselves on the wrong side of the next CPI revision or producer price updates, particularly with seasonal base effects starting to wash through in the third quarter.
In sum—we have data moving gently in a direction that warrants continued responsiveness. If future Eurozone prints validate this trend (and that’s a big “if” depending on wage reports), we should expect further shifts in the front-end of the curve that favour carry and roll-down positioning into the summer.
