The International Mercury Cartel, 1928-1954: Controlling Global Supply

This article describes the features of the international mercury market during the first half of the twentieth century. It analyses the various market agreements made, their effectiveness, and their consequences. The period studied is little understood, although it was one in which mercury production underwent great increases. It was also one that saw persistent efforts at market manipulation, owing to a series of agreements between Spanish and Italian producers that proved very effective until the arrival of shipments of mercury produced by Soviet bloc members and by some developing countries.
