A delta of -0.50 implies that for a 1% rise in the spot rate, the price of the put option is expected to fall by 0.50%. Implied volatility (IVM), very much like interest rate yield, is always quoted in annualized percentage terms. A reading of 15.00 (i.e. 15%) is equivalent to a 1 standard deviation move on the underlying spot rate over a 1-year period. For interpreting implied volatility or expected standard deviation for a nominal 1-month period, however, the implied volatility must be de-annualized as follows IVd=IV M?112. Similarly, For interpreting implied volatility or expected standard deviation for a nominal 6-month period, however, the implied volatility must be de-annualized as follows IVd=IV M?612, and so on.
