This marks the third consecutive week of growth in the reserves, which had previously increased by $2.561 billion to $644.151 billion for the week ending May 10.
On April 5, the reserves had reached an all-time high of $648.562 billion after several weeks of increases.
For the week ending May 10, foreign currency assets, a significant component of the reserves, grew by $3.361 billion to $569.009 billion, as per data released on Friday.
In dollar terms, these assets reflect the impact of the appreciation or depreciation of non-US currencies such as the euro, pound, and yen held in the reserves.
Gold reserves rose by $1.244 billion to $57.195 billion during the week.
The Special Drawing Rights (SDRs) increased by $113 million to $18.168 billion.
However, India's reserve position with the IMF decreased by $168 million to $4.327 billion in the reporting week, the RBI data indicated.
