The country's foreign exchange reserves fell $6.687 billion to $564.053 billion in the week ended August 19, according to the Reserve Bank of India (RBI) data.
In the previous week ended August 12, the reserves declined $2.238 billion to $570.74 billion.
The drop in the reserves during the week ended August 19 was due to a fall in the Foreign Currency Assets (FCA) and the gold 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.
