Between $500 billion and $1.5 trillion (or 5% of gross world product) may be laundered every year, according to the International Monetary Fund.
The most popular sectors for laundering money are import-export companies, restaurants and hotels, retail shops and road transport, and on a larger scale, the property market and construction industry. One favourite method is to use legitimate companies. A reputable but struggling firm that needs a capital injection may be made an offer it cannot refuse. In return for controlling interest or the implanting of a stooge as manager, a gang will bail the company out, gain effective control and trade on the reputation and goodwill the company has built up.
