The figure was in line with a flash estimate released by the state-run Statistics Poland (GUS) agency at the end of last month.
In May, the prices of consumer goods and services in Poland were 4 percent higher than in the same month a year earlier, according to the state-run Statistics Poland (GUS) agency.
In April, Poland's consumer price index stood at 4.3 percent, Statistics Poland reported.
Central bank sees inflation easing
Poland’s central bank expects inflation to average 3.9 percent in 2025, before falling to 3.1 percent in 2026 and 2.4 percent in 2027, according to its latest Inflation Report released on July 4.
The bank's Monetary Policy Council this month cut its benchmark interest rate by 25 basis points, marking its second reduction since October 2023, amid signs that inflation is gradually easing.
The move lowered the reference rate from 5.25 percent to 5 percent, following a 50 basis-point cut in June.
"Inflation is falling with each quarter," central bank governor Adam Glapiński said the day after the rate decision.
He added that "in the medium term, inflation is projected to align with the NBP’s inflation target of 2.5 percent, with a permissible deviation of 1 percentage point."
Glapiński also indicated that rate-setters were open to further easing.
"If inflation drops to 2.5 percent and we expect it to stay close to that level in the coming quarters, we will lower rates very significantly," he told reporters, according to the financial news site bankier.pl.
