India's foreign exchange reserves have surged to a lifetime high of $657.2 billion, as per data released by the Reserve Bank of India (RBI) on Friday. This marks a significant increase of $5.16 billion during the week ending July 5. The jump in reserves follows a brief contraction of $1.71 billion the previous week, bringing the total to $652 billion by June 28. The current surge indicates a resumption of the upward trend seen in preceding weeks.
