The Indian rupee modestly appreciated by 1 paisa to settle at 85.53 against the U.S. dollar on Friday, buoyed by strong foreign institutional investor (FII) inflows and a slight dip in the dollar index. However, gains were tempered by rising Brent crude prices, widening trade deficit figures, and sluggish domestic equity markets. The trade deficit reached a five-month high in April due to surging imports, though export growth remained resilient.
