The country's foreign exchange reserves declined $897 million to $572.98 billion in the week ended August 5, according to the Reserve Bank of India (RBI).
In the previous week ended July 29, the reserves had risen $2.31 billion to $573.87 billion.
In the week ended August 5, the fall in the foreign exchange reserves was due to a dip in the Foreign Currency Assets (FCA), a major component of the overall reserves, as per the Weekly Statistical Supplement released by RBI on Friday.
FCA declined $1.61 billion to $509.65 billion, the data showed.
Expressed in dollar terms, FCA includes the effect of appreciation or depreciation of non-US units like the euro, pound and yen held in the foreign exchange reserves.
