Polish inflation jumps to 3% in July as fuel prices surge 15.8% after subsidy ends and oil spikes

Fuel shock drives headline inflation

Poland's flash CPI reading for July 2026 came in at 3.0 percent year-on-year, the highest since spring, after the index spent the preceding months closer to the central bank's 2.5 percent target. Month-on-month, consumer prices rose 0.8 percent. The spike was overwhelmingly a fuel story: petrol and diesel for private transport jumped 13.9 percent from June, driving the annual fuel component to 15.8 percent (up from 5.3 percent in June) and adding 0.6 percentage points to the headline rate.

The mechanism behind this increase is exactly as we assumed. Two factors hit fuel prices simultaneously: administrative and market. In July, private transport fuels rose 13.9 percent m/m and are now 15.8 percent more expensive than a year ago.

Two forces collided. The government's "Ceny Paliw Niżej" (CPN) subsidy, which had capped pump prices, expired at the end of June, lifting prices at the pump by roughly 70 groszy per litre. At the same time, Brent crude lurched from about $72 to the $90-100 range as a fresh escalation in the Iran conflict raised fears of disruption in the Strait of Hormuz. The zloty weakened, adding to the domestic cost of dollar-priced crude.

Food provides a counterweight

While fuel roared, food prices continued to exert downward pressure. The food and non-alcoholic beverages category fell 0.8 percent month-on-month and was 0.4 percent cheaper than a year earlier. Analysts at Pekao noted that low agricultural commodity prices, good supply conditions, and a price war among large retail chains kept food inflation in check. PKO BP economists, however, warned that spring frosts and the summer drought could reverse the trend in the second half of the year, with higher import volumes and fierce retail competition the only bulwarks keeping the index cool.

Higher price dynamics are concentrated mainly in categories most sensitive to fuel price increases, such as transport and organised tourism, which suggests that core pressure is not yet broad-based. Excluding the fuel effect, inflation remains practically stable.

Core inflation and creeping services costs

Core inflation (excluding energy and food) edged up to an estimated 3.1 percent year-on-year from 3.0 percent in June. Rents were rising at more than 4 percent, and the costs of housing maintenance and health services remained elevated. ING economists calculated that CPI ex-fuel stood at just 2.2 percent, underlining how the headline move is almost entirely a petroleum story. Still, warnings were sounded. Mariusz Zielonka, chief economist at Lewiatan, said that if Brent holds above $90 per barrel, higher transport and fuel costs would gradually seep into the prices of services and food, potentially locking core inflation above 3 percent for longer than a one-off VAT effect would imply.

Eurozone backdrop and ECB inertia

The eurozone, too, felt the energy pulse. Flash data showed core HICP accelerating to 2.5 percent year-on-year in July from 2.4 percent in April, while the energy component leaped to 10.0 percent (from 8.5 percent in June). Services inflation printed 3.3 percent. The ECB's Governing Council kept interest rates unchanged at its Thursday meeting, having already delivered a first hike since 2023 at its previous sitting. The highest national readings were in Lithuania (5.6 percent), Bulgaria (4.1 percent) and Cyprus (4.0 percent); the lowest were in Estonia (2.0 percent), Malta (2.1 percent), Latvia (2.5 percent) and Finland (2.6 percent).

Policy path and the months ahead

With headline CPI tipped to drift toward 4 percent later in the year, the outlook for monetary easing dimmed. Analysts at Pekao and Erste project both CPI and core inflation to stay inside a 3.0-3.5 percent band through the end of 2026, peaking near the turn of the year as poor weather lifts food prices. Erste expects inflation to reach the upper bound of the NBP's tolerance band by the fourth quarter and sees interest rates on hold through 2026-2027. PKO BP said the rise "may discourage the Monetary Policy Council from quickly resuming rate cuts, though it does not close that path entirely." ING was blunt.

These are not conditions for filing a motion for an NBP rate cut after the holidays.
