Some of the revenue of the Gulf Cartel is often laundered in several bank accounts, properties, vehicles, and gasoline stations. Bars and casinos are often the hubs for money laundering of the drug cartels. Top leaders of the Gulf organization, like Juan García Ábrego, Osiel Cárdenas Guillén, Jorge Eduardo Costilla Sánchez and Antonio Cárdenas Guillén, among others, have been charged by the U.S. government for laundering millions of dollars. Bank accounts inside the United States also launder millions of dollars for the drug lords of the Gulf Cartel. "The Economist" mentioned in 1997 that the drug money from the Gulf Cartel in the Rio Grande Valley was perhaps moving about $20 billion, and that around 15% of the retailers' gains were from drug money.
