Foreign exchange reserves, also called forex reserves, are, in a strict sense, only foreign currency deposits held by national central banks and monetary authorities. However, in popular usage, it also includes gold reserves, special drawing rights (SDRs) and International Monetary Fund (IMF) reserve position because this total figure, which is usually more accurately termed as official reserves or international reserves or official international reserves, is more readily available and also arguably more meaningful.
