Revenue from commodity trading, selling derivatives to investors and other activities in the sector fell to $4.3 billion (£3.5 billion) in 2016 from $4.6 billion the previous year, it said in a report.

"Underperformance in oil was partially offset by an improvement in U.S. power and gas on the back of structured deal activity. Metals ended the period flat with some improvement in precious metals," it said.

Commodity revenue in the fourth quarter jumped 20-25 percent mainly due to power and gas activity, Coalition said last month in a preliminary report that did not provide full-year figures.

Coalition tracks Bank of America Merrill Lynch (>> Bank of America Corp), Barclays (>> Barclays PLC), BNP Paribas (>> BNP Paribas), Citigroup (>> Citigroup Inc), Credit Suisse (>> Credit Suisse Group AG), Deutsche Bank (>> Deutsche Bank AG), Goldman Sachs (>> Goldman Sachs Group Inc), HSBC (>> HSBC Holdings plc), JPMorgan (>> JPMorgan Chase & Co.), Morgan Stanley (>> Morgan Stanley), Societe Generale (>> Société Générale) and UBS (>> UBS Group AG).
