When valuing European options in the early 1970s, Fischer Black, Myron Scholes and Robert Merton (BSM) showed that, over any short period of time, an investment in an option could be replicated with a portfolio of stock and risk-free debt. This observation allowed them to calculate the economic value of the option by solving a differential equation. Subsequent analysis showed the economic value of the option could also be determined by discounting the expected payoff on the option in a risk-neutral world at the risk-free rate of interest. The calculated value is “economic” in the sense that, if the option price were different from this value, an investment in the option would dominate an investment of equivalent risk in a portfolio of debt and equity. The BSM analysis also showed that if it were possible to borrow and lend at the risk-free rate of interest, the replicating portfolio could be used as a hedge for the option.
Prior to the credit crisis that started in 2007, the London Interbank Offered Rate (Libor) was thought to be the best proxy for the risk-free rate, and it was assumed banks could borrow and lend at that rate, allowing them to carry out the replicating trading
