Wall Street Refiner

“Wall Street refiner” is a term that began in 1987-88, when Wall Street financial institutions became involved in the oil business. Wall Street has no refineries, of course. Firms such as Morgan Stanley, Salomon Brothers and Goldman Sachs were well known “Wall Street refiners” for selling oil derivatives.

Trading in Oil Futures and Options
By Sally Clubley
Boca Raton, FL: CRC Press
1998
Pg. 34:
The last ten years have seen the emergence of a new type of trader: the Wall Street refiners. They were given this name when the US investment banks set up oil trading arms to deal in oil derivatives in much the same way as they deal in other financial instruments. They are assuming the risk for a number of companies involved in the oil markets and laying these risks off in the physical or future markets in the same way as an insurance company does in other sectors. Several of them also take substantial outright positions in their own right. They have been in existence since around 1987 and made an immediate impact on the oil industry worldwide.
