Fed vs ECB Rate Path Divergence Still the Key EUR/USD Driver

With diesel prices at record highs feeding into inflation data the Fed and ECB both track closely, the policy divergence narrative that has anchored EUR/USD trading remains firmly intact heading into this week's releases.

Markets will parse whether US inflation stickiness forces the Fed to hold rates higher for longer relative to the ECB, since any widening or narrowing of that expected gap is typically the single biggest swing factor for EUR/USD positioning among institutional desks.

Traders should treat the upcoming CPI data less as a standalone US event and more as a comparative input, since the eurozone's own energy cost pass-through will determine how symmetric — or asymmetric — the central bank responses turn out to be.
