Mumbai, March 21 (IANS) India's foreign exchange reserves plunged by $5.34 billion during the week ended March 13. According to the RBI's weekly statistical supplement, the overall forex reserves, which are already at a record high, decreased to $481.89 billion from $487.23 billion reported for the week ended March 6.

On a weekly basis, FCAs, the largest component of the forex reserves, fell by $3.77 billion to $447.35 billion. Similarly, the value of the country's gold reserves declined by $1.53 billion to $29.46 billion.
