The manufacturing Purchasing Managers' Index, or PMI, fell to 52.7 in March from 54.7 in February. A PMI reading above 50 suggests expansion in the sector.

"The tragic development of war in Ukraine had an inevitable destabilizing impact on the Polish manufacturing sector in March," Paul Smith, economics director at S&P Global, said.

Production declined for the first time in fourteen months in March and a contraction in sales ended a 15-month sequence of growth.

Export orders dropped to the steepest since mid-2020 and suppliers' delivery time was delayed due to Russia-Ukraine war. Input price inflation rose to the highest since July last year.
