The country's foreign exchange reserves increased by $2.198 billion to $631.953 billion in the week ended February 4, RBI data showed.
In the previous week ended January 28, the reserves had declined by $4.531 billion to $629.755 billion. It touched a lifetime high of $642.453 billion in the week ended September 3, 2021.
During the reporting week, the surge in the foreign exchange reserves was on account of a rise in the Foreign Currency Assets (FCA), a major component of the overall reserves, and gold reserves, according to the Reserve Bank of India's (RBI) weekly data released on Friday.
FCA increased by $2.251 billion to $568.329 billion in the week ended February 4.
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.
