"The highlight event is tonight's FOMC minutes which can set the mood until next Fed policy. The USDINR spot market is volatile ahead of the minutes on hopes that it may indicate the timing of tapering the quantitative easing," said Rahul Gupta, Head Of Research- Currency, Emkay Global Financial Services.
"If the minutes suggest a delay in tapering due to the risks of the economic outlook, we can see some reversal in USDINR spot. The immediate resistance is around 74.95-75 zone, while immediate support is at 74.50-74.25. Only consistent trading above 75 will open doors for 75.25," Gupta said.
