The Index calculation is based on the official exchange futures settlement prices of the first nearby contract

Therefore, RB and HO contracts are converted from “cents/gallon” to “USD/barrel” using a standard conversion factor of 1 barrel = 42 US gallons.

The data are calculated in ZE Power, using NYMEX settlement prices as input. An algorithm will then weight the inputs and calculate the index.

Which CME Group products impact the CME Group Petroleum Index?

The percentage weight of each futures contract within the Index is based on the respective average open interest volumes for the last quarter of the calendar year, from October 1st to December 31st inclusive. The Administrator reviews the weights of each component at the end of the calendar year and makes a recommendation to the Oversight Committee.

In the event that weightings have changed by more than 3% (three percent) versus the previous year, the weights must be adjusted accordingly. Changes to the weights will be advised to stakeholders and applied on the first day of the second quarter of the following year.

At launch, the weights of each component within the CME Group Petroleum Index are set as follows:
