For the first time this year, Poland's annual inflation rate probably rose, due to a weaker złoty and a smaller-than-expected food-price drop, the Finance Ministry said.

From a three-year low of two percent in July, the inflation rate probably rose to 2.1 percent, Bloomberg reports the Finance Ministry as estimating. Analysts contacted by Bloomberg predict August inflation will stand at 2.2 percent.

The NBP's target inflation rate is 2.5 percent y/y, plus or minus one percentage point.

Coupled with higher-than-expected GDP growth, an increase in inflation may well prompt the central bank to hike interest rates.

Official inflation data will be revealed on September 14.
