Poland's Q3 GDP growth expected at just over 4.5 pct - finance ministry

WARSAW, Nov 2 (Reuters) - Poland's gross domestic product for the third quarter probably grew slightly more than 4.5 percent in annual terms and in the whole of 2017 it may grow just above 4 percent, Deputy Finance Minister Leszek Skiba told Reuters.

"I expect third-quarter GDP growth to be slightly above 4.5 percent, year-on-year, and the annual growth dynamics will slow down in the fourth quarter because of base effect," Skiba said in comments cleared for publication on Thursday.

Base effect measures relative change from an earlier period. In the last quarter of 2016, Polish economy grew 3.1 percent, the strongest in the whole year, meaning that an increase during the last three months of 2017 will be less pronounced.

Poland's Central Statistical Office will release preliminary third-quarter GDP data on Nov. 14. Economists polled by Reuters estimate that the economy grew 4.4 percent between July and September.

Skiba said that in the second part of the year gross fixed capital formation will be an increasingly important component of economic growth.

"The contribution of domestic consumption will be diminished," Skiba said, adding that the effect from the a family subsidy introduced by the ruling Law and Justice party would fade. (Writing by Lidia Kelly, editing by Larry King)
