The Indian rupee opened at Rs 45.48 per dollar versus Rs 45.45 yesterday.
Subramaniam Sharma, Greenback Forex Services said that, "The rupee is likely to remain strong and could gain further after S&P revised India's rating to stable. Positive sentiment in domestic equity market driven by inflows, a weaker euro and importer demand at lower levels could cap rupee's gain and could halt its appreciation. The range for the day is seen between 45.30-45.55/$."
