The reserves stood at USD 288.26 billion during the previous week. It was for the fourth consecutive week that the reserves have gone down.
The fall in reserves was possibly due to the dollar selling by the apex bank to prop up the rupee as also due to fall in international gold prices during the period.
Changes in foreign currency assets, expressed in dollar terms, include the effect of appreciation/depreciation of other currencies held in its reserves, the RBI said.
As of June 1, the foreign currency assets slipped to USD 253,094 million from USD 254,406 million.
During the year-ago period, it stood at a high USD 280,908 million.
