The chart above demonstrates the continuous cycle of the Black Market Peso Exchange (BMPE). The cycle begins in the lower left hand corner of the chart with the transportation of cocaine and heroin from Colombia. After the drugs are sold for U.S. currency, the cash is sold, at a discount, to a BMPE broker. The broker acts as an underground banker by swapping the trafficker dollars for Colombian pesos owned by "legitimate" South American businessmen. The businessmen use these U.S. dollars (usually converted to checks or wire transfers) to buy large volumes of durable and consumable goods from manufacturers and distributors of goods in the U.S.
