In the previous week, the reserves had risen $1.574 billion to $354.28 billion.
Foreign currency assets, a major component of overall reserves, swelled $1.13 billion to $330.71 billion in the reporting week, the data showed.
Expressed in dollar terms, these include the effect of appreciation and depreciation of non-US currencies such as the euro, the pound and the yen held in the reserves.
According to an HSBC report, the country's foreign exchange reserves are above traditional levels, but the country's peculiar characteristics and experience in recent crises suggest that about $60 billion more could buffer sufficiently a prolonged global financial tightness.
"We estimate an additional $60 billion of reserves, taking overall holdings to $420 billion, could take care of key vulnerabilities such as unhedged external commercial debt, short-term external debt and portfolio outflows," the report said.
In FY15, there was an accretion of foreign exchange reserves to the tune of $61.4 billion compared with $15.5 billion last year.
In the week to June 19, the country's gold reserves remained unchanged at $19.34 billion.
The special drawing rights with the International Monetary Fund were up by $26.6 million to $4.07 billion while the country's reserve position with the fund surged $8.5 million to $1.32 billion, the data showed.
