Poland CPI: Fuel shock strengthens the case for higher rates
Polish inflation accelerated to 4.0% YoY in September from 3.4% in August, the highest reading in 15 months and now clearly above the NBP’s tolerance band.
The headline matched consensus, while prices rose 0.7% MoM, a touch below the 0.8% expected. Even so, the composition was striking. Fuel prices jumped another 9.2% on the month and are now 36.1% higher than a year ago, confirming the concern we highlighted ahead of the release: after pump prices surged through September, it was increasingly difficult to see headline inflation remaining close to August’s reading.

For now, this remains primarily an energy shock rather than evidence of a broad-based inflation breakout.
Food prices rose just 0.1% MoM and remain 0.5% lower than a year ago, while electricity, gas and other household energy prices increased 0.9% MoM and 4.9% YoY. Fuel is therefore doing much of the heavy lifting. That distinction matters for the NBP, as policymakers may still be willing to look through part of the initial shock if underlying inflation remains contained. But with energy costs elevated and no immediate relief visible at Polish pumps, the risk is increasingly that higher transport and energy costs begin feeding into wider price-setting over the coming months.
That leaves the rate outlook looking notably more hawkish than just a few weeks ago.
The NBP reference rate remains at 3.75%, following the March cut to that level. NBP Governor Adam Glapiński has suggested rates could remain unchanged for an extended period, but today’s data make that stance harder to maintain indefinitely if inflation stays above target. MPC member Ludwik Kotecki has already said that rate-hike discussions could begin in October, with November potentially live if new projections show inflation remaining above 4%. Still, with September CPI matching consensus and the monthly print undershooting expectations, we think the bar for an immediate hike remains high. The key question is whether the current fuel shock remains concentrated in headline inflation or begins to generate second-round effects. That said, the balance of risks has shifted enough that we now think at least one rate hike by early 2027 should be treated as a serious possibility, especially if inflation remains above 4% and underlying price pressures begin to firm.
For PLN, today’s data are supportive rather than transformative.
A 4.0% print was already expected, limiting the immediate surprise, but the policy implications are increasingly difficult to ignore. If inflation remains above the NBP’s tolerance band and evidence of broader pass-through emerges, the November projection could become the point at which the current discussion over possible tightening turns into a much more concrete policy debate. Until then, the shift away from easing expectations should provide the zloty with some support, even as fiscal and geopolitical risks remain important counterweights.
