The gold certificate account reflects the receipts issued to the Reserve Banks by the Treasury against its gold holdings. In return, the Reserve Banks issue an equal value of credits to the general account of the Treasury, computed at the statutory price of $42.22 per troy ounce. Because nearly all of the gold held by the Treasury has been monetized in this fashion, the Federal Reserve Banks' gold certificate account of $11 billion represents the nation's entire official gold stock.
