ECB Hawk Path Firms After Eurozone Core CPI Hits 2.5%

EUR/USD and the Rate Differential Play

The immediate consequence for EUR/USD is a higher floor. The 1.0800 handle, which had been tested twice in the prior fortnight, now looks like a structural bid zone unless US data surprises to the upside on a similar scale. The 2-year swap rate differential between the euro and the dollar narrowed by 3 basis points on the print, a move that typically takes several sessions to fully feed into spot.

Traders should watch the EUR/USD risk reversal structure for clues. A shift in one-week 25-delta puts relative to calls would confirm whether the options market is pricing a sustained policy divergence. If the ECB is forced into a second hike in September while the Fed remains on hold, the euro could climb toward 1.1100 by Q4. That scenario depends on the July HICP reading confirming the stickiness.

The Decision Point the Story Creates

The question for August is whether this core print is a one-off seasonal distortion or the start of a trend. Services inflation, which accounts for the largest share of core HICP, has proven resistant to the ECB's tightening so far. A second consecutive beat in the July release would effectively lock in a September hike and likely push the terminal rate above 4.00% .

For now, the market is pricing a 95% probability of a July hike and about 60% for another move in September. Today's core CPI overshoot nudges that September probability toward 70% . The next concrete test comes with the flash July PMIs and the Q2 wage tracker, both of which will either confirm or erode this hawkish repricing. A miss on both would bring the long-end curve back into play and cap the euro's upside.
