Modern development

The act of "money laundering" was not invented during the Prohibition era in the United States, but many techniques were developed and refined then. Many methods were devised to disguise the origins of money generated by the sale of then-illegal alcoholic beverages. Following Al Capone's 1931 conviction for tax evasion, mobster Meyer Lansky transferred funds from Florida "carpet joints" to accounts overseas. After the 1934 Swiss Banking Act, which created the principle of bank secrecy, Meyer Lansky bought a Swiss bank to which he would transfer his illegal funds through a complex system of shell companies, holding companies, and offshore bank accounts.

The term "money laundering" does not derive, as is often said, from Al Capone having used laundromats to hide ill-gotten gains. It was Meyer Lansky who perfected money laundering's older brother, "capital flight," transferring his funds to Switzerland and other offshore places. The first reference to the term "money laundering" itself actually appears during the Watergate scandal. US President Richard Nixon's "Committee to Re-elect the President" moved illegal campaign contributions to Mexico, then brought the money back through a company in Miami. It was Britain's The Guardian newspaper that coined the term, referring to the process as "laundering."
