* Suspected RBI intervention around 50.25/dlr aids-traders * Dollar demand from oil importers peaks at month end * Profit taking follows sharp gains in rupee (Adds details, quotes, updates to close) By Aditya Phatak MUMBAI, Jan 25 (Reuters) - The Indian rupee fell on Wednesday as dollar demand from oil importers for month-end payments offset a rise in the local share market, although traders said likely dollar sales by the central bank pulled it off the day's low. Oil is India's largest import item and refiners are the biggest buyers of dollars in the local market. The partially convertible rupee ended at 50.09/10 to the dollar, little changed from Tuesday's close of 50.07/08, but stronger from the day's trough of 50.25, where traders suspect the Reserve Bank of India to have sold dollars. "There is strong bidding interest for the dollar around 50 levels and oil buying has been around through the day," said Ashtosh Raina, head of foreign exchange trading at HDFC Bank. He forecasts 48.60 as the next resistance level for the rupee it breaks past 49.80 against the dollar. Reluctance to carry big positions ahead of the U.S. Federal Reserve's rate decision due late Wednesday evening and a local market holiday on Thursday weighed on the rupee, traders said. Lingering fears about the prospect of a Greek debt default also kept the mood cautious. The U.S. Federal Reserve opened a two-day meeting on Tuesday that is expected to end with a signal that interest rates will be held near zero into 2014. A statement is due at 1730 GMT on Wednesday. A sharp rebound in the rupee from its record low of 54.30 on Dec. 15 also prompted some profit taking, traders said. The rupee has gained 6 percent so far in January after declining 16 percent in 2011. Traders attribute the rupee's rise to RBI intervention and steps taken by it to cut speculation and boost dollar flows, and were concerned it may fall once the central bank moves back into the background. The RBI chief on Wednesday said intervention by the central bank in the foreign exchange market will depend on the rupee's exchange rate and capital flows.
