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.

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.
