2. Exchange Rate Volatility
A decline in actual volatility of the exchange rate in parallel with a decline in implied volatility.
The standard deviation of changes in the shekel-dollar exchange rate, which represents its actual volatility, declined by about 2.7 percentage points in April, to 6.1 percent at the end of the month.
The average level of implied volatility in over the counter shekel-dollar options declined by about 0.8 percentage points, to 7.3 percent at the end of April.
In parallel, the implied volatility in foreign exchange options in emerging markets declined, to an average of about 10.1 percent, and the implied volatility in foreign exchange options in advanced economies also declined, to about 8.3 percent at the end of April (Figure 4).
The implied volatility in foreign exchange options trading is an indication of expected exchange rate volatility.
