Oil’s implied volatility
On December 6, US crude oil’s implied volatility was 48.1%, which was 1.5% above its 15-day average. You can see the inverse relationship between oil prices and oil’s implied volatility is in the following graph. Since reaching a 12-year low in February 2016, US crude oil active futures have risen 96.5%. Crude oil’s implied volatility has fallen 36% since February 11, 2016.
On December 7–14, US crude oil futures should close between $48.31 and $54.67 per barrel 68.0% of the time. The forecast is based on crude oil’s implied volatility of 48.1% and assumes a normal distribution of prices. With OPEC’s decision on the production cut, which we discussed in Part 1, US crude oil might break this price range.
On December 6, US crude oil January futures fell 2.6% and settled at $51.49 per barrel. If US crude oil reaches the lower limit of our price forecast, it would be the lowest closing level for active US crude oil futures in 2018.
