India's foreign exchange reserves declined by $956.4 million to $368.998 billion for the week ended April 7 due to fall in foreign currency assets, the Reserve Bank of India said.
The reserves had increased by $2.022 billion to $369.954 billion in the previous reporting week.
They had touched a lifetime high of $371.99 billion in the week to September 30, 2016.
Foreign currency assets (FCAs), a major component of the overall reserves, dipped by $951 million to $345.367 billion in the reporting week, RBI said.
Expressed in US dollar terms, FCAs include the effects of appreciation/depreciation of non-US currencies, such as the euro, pound and the yen, held in the reserves.
