Economy growing, inflation falling: finance minister
Finance and Economy Minister Andrzej Domański said inflation was easing and the economy gaining momentum.
"Inflation in November fell to 2.4 percent, from 2.8 percent in October," he wrote, adding the reading was "below analysts’ expectations and below the central bank target."
"The economy is revving up, while inflation is falling rapidly," Domański said, promising that "2026 will be an even better year" for Poles.
November's reading was the fifth consecutive month within the central bank's 2.5-percent target range, with a margin of 1 percentage point in either direction, analysts said.
Inflation was 2.8 percent in October and 2.9 percent in September, according to the Statistics Poland (GUS) agency.
The government’s 2025 budget assumes average inflation of 3.1 percent next year.
The central bank, in a November forecast, predicted inflation would average 3.7 percent in 2025 before easing to 2.9 percent in 2026 and 2.5 percent in 2027.
