Anindya Banerjee, DVP, Currency Derivatives & Interest Rate Derivatives at Kotak Securities Ltd, "USD-INR spot closed flat near 75.10 levels. Inspite of the war of words between Russia and Ukraine and NATO, USD-INR remained in a non-trending phase. Bids from PSUs absorbed whatever inflows happened from corporates. Over the near term, USD-INR may remain range bound within 74.70 and 75.35 on spot, due to lack of fresh triggers.
Dilip Parmar, Research Analyst, HDFC Securities, said, "The local unit is struggling near the psychological level of 75 as safe haven dollar remained in demand amid ongoing speculation of Fed tightening in March meetings along with geopolitical worries,"
Spot USDINR expected to find support in the range of 74.90 to 75, while 75.70 remains the biggest hurdle, Parmar added.
