Energy commodity prices increased in the second half of 2017

U.S. Energy Information Administration --------- After decreasing nearly 20% in the first half of 2017, the spot energy index in the Standard and Poor's (S&P) Goldman Sachs Commodity Index (GSCI) ended 2017 16% higher than the beginning of the year. Higher crude oil and petroleum product prices in the second half of 2017 were responsible for the increase in the S&P GSCI energy index. West Texas Intermediate (WTI) and Brent, two major crude oil benchmarks, account for 70% of the weighting in the S&P GSCI energy index. As a result, the energy index tends to follow major price movements in the crude oil market. The weights associated with individual commodities within the S&P GSCI index are updated every year in response to changes in global commodity production quantities and futures contract trading volumes.
