The rupee opened on a positive note, surpassing 83.05 with a gain of 0.25rs. The surge is amid the significant drop in the dollar index, which fell more than 1% to 104.15$ from 105.35$. The trigger for this decline was the lower-than-expected US CPI data released yesterday evening at 3.20% against 3.7% last month. The data suggested a decrease, providing support to the view that the Fed may not opt for an immediate interest rate hike. This led to a weakening of the dollar against other currencies, benefiting the rupee. However, profit booking in the rupee caused some retracement of the initial gains. The rupee's range is expected to fluctuate between 82.90-83.30 amid these dynamics.
