Polish CPI Prel (Aug MM) 0.4% vs. Exp. 0.2% (Prev. 0.8%)

Polish monthly CPI has come in above consensus at 0.4%, though decelerating from the prior 0.8%, a combination that leaves the signal mixed: the beat argues the disinflation path is bumpier than priced, the slowdown in the monthly run-rate argues it remains intact. Polish inflation prints of this kind are typically filtered through the NBP's reaction function, where the council has historically split between a dovish majority and a hawkish minority, so the market read tends to hinge less on the print itself than on whether it shifts the median voter on the timing of the next rate move. The transmission channel is the front end of the PLN curve and the short-end OIS path, with the zloty responding through the rate differential against the euro rather than through any inflation-risk premium channel. Flash readings in Poland are subject to revision when the final print lands, and the year-on-year figure matters more for the council's communication than the monthly one, so the follow-ons are the final release and the tone of subsequent NBP commentary, particularly around administered and regulated price components, which have repeatedly distorted the headline in this series.
