While gold took a tumble, foreign currency assets actually grew by $2.13 billion to $557.7 billion, mostly because of shifting values among global currencies like the euro and the pound against the dollar.
Special Drawing Rights (SDRs) slipped slightly by $65 million, and India's position with the International Monetary Fund nudged up by $19 million to reach $4.83 billion.
Overall though, it was that sharp fall in gold that really moved the needle this time around.
