WHAT: Third quarter GDP forecast +6.6 percent, versus +6.7 percent in second quarter WHEN: Release date: Nov 15, 0800 GMT * Interest rates seen rising By Martin Santa BRATISLAVA, Nov 13 (Reuters) - Slovak economic growth probably eased a touch in the third quarter of this year, a Reuters poll showed on Monday, but is expected to remain robust enough to sustain expectations of further interest rate rises. The median forecast in the poll of 10 analysts showed real annual gross domestic product (GDP) growth of 6.6 percent, compared with 6.7 percent in the second quarter of 2006. The Slovak Statistics Office will publish its flash estimate of third quarter GDP data on Wednesday. The Slovak economy has had one of the fastest growth rates in the European Union in the past four years, fuelled by household consumption and rising investments, mainly into the automotive sector. "Household consumption should have remained strong. Despite this, we expect a slight deceleration, as well as in government consumption and investment activity," Komercni Banka analyst Anne-Francoise Bluher said, adding the data should show a positive contribution from net exports. Household consumption in Slovakia rose by 5.9 percent on the year in the second quarter, a slowdown from the 6.6 percent reported in the first three months of 2006. The central bank (NBS) has raised the key two-week repo rate by 175 basis points in four steps so far this year, saying strong domestic demand poses inflation risks. Inflation is the main threat to Slovakia's plan to adopt the euro in 2009. The statistics office will not release details of the third-quarter GDP data until Dec. 7, but analysts said high headline growth figures would add to expectations that the central bank would raise interest rates again. "There is some risk, based on the latest retail sales and foreign trade data, that consumption could be above forecasts," said Lucia Steklacova, a senior analyst at ING Bank in Bratislava, adding that growth in employment and wages also posed risks to inflation. "That is why we still see a risk of an interest rate hike." Analysts and the central bank expect Slovak economic growth to accelerate to over 7 percent next year thanks to rising exports from new car factories set up by French PSA Peugeot Citroen <PEUP.PA> and South Korean Kia Motors <000270.KS>.
