COMMENTARY: JURAJ VALACHY, ANALYST, TATRA BANKA, BRATISLAVA "CPI was in line with predictions. Overall, the data can be seen as positive. They should not spark any reaction in monetary policy settings, or on the market. Annual inflation should fall significantly in January." SILVIA CECHOVICOVA, ANALYST, CSOB BANK, BRATISLAVA "Inflation was slightly better than expected, but it is no big surprise. I think the data will have a neutral impact on monetary policy. Rates will stay unchanged, and the inflation outlook is favourable. The annual inflation rate is expected to fall to near 3 percent in January because of the base effect." MARKET REACTION: The crown showed no immediate reaction to inflation data, trading flat at 34.520 to the euro as of 0805 GMT. BACKGROUND: - Inflation data were calculated according to domestic methodology. - The central bank more closely follows inflation calculated under the EU-harmonised consumer price index, but the market pays attention to local data as they signal trends with shop prices. - The Statistics Office will release EU norm inflation data for December on Jan. 17. - The central bank sets its inflation targets according to EU norm data as part of Slovakia's preparation for joining the euro in 2009. - Slovak inflation accelerated in 2005 and 2006 due to hikes in natural gas and heating prices. - The central bank raised the key two-week repo rate by 175 basis points in 2006 to fend off inflation risks stemming from high energy prices and fast economic growth. - A Reuters poll earlier this week showed all analysts expecting the two-week repo to stay unchanged at 4.75 percent in January.
