Following the LIBOR scandal we need to take a look at gold and silver lease rates, because lease rates are calculated as LIBOR - GOFO (London Interbank Offered Rate - Gold Forward Offered rate).
The London Interbank Offered Rate is the average interest rate estimated by leading banks in London that they would be charged if borrowing from other banks. GOFO is the interest we need to pay if we swap gold for U.S. dollars. Whenever GOFO goes down (or gold lease rates go up), it means people are craving to get their hands on gold. At the same time, when LIBOR goes up (or gold lease rates go up), it basically means the same: higher gold prices to come.
