"The Indo-China border skirmish is keeping the USD-INR spot afloat. Also, RBI is seen protecting the fall in spot.
The USD-INR spot has not broken the crucial resistance of 73.75, on subdued dollar ahead of today's (Wednesday) US Fed outcome," said Rahul Gupta, Head of Research - Currency, Emkay Global Financial Services.
Gupta further said that "we don't expect any changes in tonight's monetary policy but the main focus will be on details over measures to boost economic growth.
If Fed sounds less dovish than expected while providing details over average inflation targeting, then we can expect an uptick in dollar index and further rise in USD-INR spot".
