NYMEX RBOB Gasoline 13%
NYMEX NY Harbor ULSD 15%

The Index calculation is based on the official Exchange Futures daily settlement prices of the above future contracts.

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 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.
