Diesel prices at Polish fuel stations have risen sharply over the past week, with costs increasing by several groszy per liter in just a few days.
The rapid escalation in pump prices reflects the immediate transmission of higher international crude oil benchmarks to downstream retail markets.
In May, diesel prices in the eurozone jumped 29% year-on-year, while gasoline rose 16%.
Analysts at e-petrol.pl noted that diesel has been the fastest-rising fuel category in recent days.
The surge follows a broader rally in global crude oil markets, which has dragged up the valuations of downstream derivatives and signaled immediate cost pressures for transport and logistics operators.
The development in Poland mirrors a wider trend across the European Union, where fuel costs have been a primary driver of consumer price inflation.
