I believe the answer is:

opec

(Other definitions for opec that I've seen before include "Organisation intended to control the production and sale of petroleum" , "Group of countries with a common oil policy" , "Cartel of oil-producing countries" , "Group of petroleum producing countries, formed in 1961" , "International oil-producing cartel" .)

I've seen this clue in The Wall Street Journal.
