Mumbai: The Indian rupee settled 6 paise lower at 70.90 to the US dollar on Wednesday as participants exercised caution ahead of the Federal Reserve's monetary policy decision.
However, the rupee loss was somewhat capped by unabated foreign fund inflows, domestic stocks rally and lower crude oil prices.
Starting off weaker, the domestic currency went on to hit a low of 71.03 against the US dollar during the day. It, however, claimed some of its lost ground to settle at 70.90, showing a fall of 6 paise over its previous close.
Globally, markets are keenly awaiting the outcome of the all-important Federal Open Market Committee (FOMC) monetary policy decision, which will be announced at 1800 GMT on Wednesday.

The 10-year government bond yield was trading at 6.50 per cent.

"Rupee failed to move out of the range and continued to consolidate in a narrow range as most market participants remained cautious ahead of the important FOMC policy statement that will be released today. Expectation is that the central bank could cut rates by 25 bps and adopt a hawkish stance thereby keeping the dollar supported on lower level," said Gaurang Somaiyaa, forex and bullion analyst, Motilal Oswal Financial Services.
"US GDP and private payrolls number will also be keenly watched and better-than-expected number could extend further gains for the greenback. We expect the USDINR(Spot) to quote in the range of 70.70 and 71.30," he said.
