PRAGUE, Feb 7 (Reuters) - The Czech central bank raised interest rates by 25 basis points on Thursday to tame inflationary pressures, as widely expected, but said the next move could be in either direction as inflation and economic growth cool.
The increase brought the key two-week repo rate to 3.75 percent, 200 basis points up since 2005.
The crown currency reacted by rising to near all-time highs, but later fell after the bank forecast that market interest rates will drop by next year.
The Czech move followed three other central banks in central and eastern Europe that tightened the monetary screws over the past week, while the Bank of England on Thursday loosened policy due to growth concerns and the European Central Bank made no change.
Czech rates remain the lowest in the European Union and below the current inflation rate but analysts said they may not go any higher due to an expected slowdown in both foreign and domestic demand, especially if the currency remains strong.
The central bank cut its economic growth forecast for this year to 4.1 percent from 5 percent, and next year's to 4.6 from 5.6 percent and reiterated it saw inflation falling next year.
"It is quite possible that the next (rate) move will be upwards, and it is quite as well possible, if the risks materialise in the opposite direction, that the next move will be downwards," Central Bank Governor Zdenek Tuma said.
The crown briefly firmed after the decision before giving back the gains. It later fell to 25.730 to the euro <EURCZK=> at 1610 GMT, off all-time highs at 25.545 on Thursday morning.
The currency has gained 9 percent against the euro over the past 12 months as exports have grown and the negative Czech interest rate spread versus the euro zone has narrowed to 25 basis points, following Thursday's decision.
Tuma said the crown's rise was tightening monetary conditions, and would have policy implication if it continues.
Inflation jumped to 5.4 percent in December, far above the central bank's target of 3 percent +/- 1 percentage point, and analysts expect it to have surpassed 6 percent in January. The data is due out on Friday.
The bank predicted inflation would fall back to 2.4 percent in mid-2009, as the bank cuts its inflation target to 2 percent as of 2010.
LOW MARKET RATE FORECAST
The bank for the first time revealed, in the form of a fan chart, where it saw interbank market interest rates going, although Tuma stressed there was no commitment for the policymakers in the prediction.
The prediction showed a slight rise of the 3-month interbank rate in early 2008 -- which may be reflected by the hike on Thursday -- and then a fall to 3.2 percent at the end of 2008 and 2.9 percent in mid-2009, with rising uncertainty.
The forecast surprised some traders and analysts.
"The prediction is very low related to the current yield curve," said Dalimil Vyskovsky, money market trader at Komercni Banka.
"The alternatives will of course depend on economic development, however the initial reaction of the market was of course toward lower rates, forward rate agreements in the given horizon went about 10 basis points down," he said.
