Polish CPI Prel (Aug YY) 3.4% vs. Exp. 3.1% (Prev. 3%)

A preliminary print running above consensus and above the prior reading marks the second consecutive re-acceleration in Polish inflation, interrupting what had been a disinflationary trend that underpinned the central bank's easing bias. Episodes of this kind in Poland have historically put the rate path in play quickly: the NBP has shown itself willing to move on energy-driven and administered-price inflation rather than look through it, and upside surprises have tended to stiffen the more cautious wing of the council. The transmission is direct, via front-end yields and the zloty, with hawkish repricing in the short end of the WIBOR curve the usual first response. The distinction worth drawing is between flash and final: the preliminary release lacks the basket detail, so the composition, whether the overshoot sits in food, energy, or services, is the tell that separates a pass-through blip from broadening pressure. The follow-ons are the final print with its breakdown, and the tone of council commentary ahead of the next decision, where prior form suggests a hot run of prints has been enough to stall or reverse cuts.
