Energy prices used in the S&P Goldman Sachs Commodity Index (GSCI) ended 2021 59% higher than the first trading day of the year. Price increases were largely driven by increased demand from the initial phase of global economic recovery from the COVID-19 pandemic. By comparison, most other commodity indexes included in the GSCI increased by about 20%. The precious metals index was the only one to decline. The energy index of the GSCI increased more than twice as much as the industrial metals index on a percentage basis during 2021, the next highest commodity index group price change.
