In the week ago period, the reserves had risen by $2.691 billion to $286.26 billion.
FCAs, which form a major part of the overall reserves, rose by $5.071 billion to $263.736 billion for the week under review, the RBI said.
FCAs, expressed in dollar terms, include the effect of appreciation or depreciation of the non-US currencies such as the euro, pound and yen, held in reserves.
