An informal value transfer system (IVTS) is any system, mechanism, or network of people that receives money for the purpose of making the funds or an equivalent value payable to a third party in another geographic location, whether or not in the same form. Informal value transfers generally take place outside of the conventional banking system through non-bank financial institutions or other business entities whose primary business activity may not be the transmission of money. The IVTS transactions occasionally interconnect with formal banking systems, such as through the use of bank accounts held by the IVTS operator.
Informal Value Transfer System (IVTS) is an alternative and unofficial remittance and banking system, that pre-dates current day modern banking systems. The systems were established as a means of settling accounts within villages and between villages. It existed as far back as over 4000 years ago and even more.
Their use as global networks for financial transactions spread as expatriates from the original countries settled abroad. Today, IVTS operations are found in most countries. Depending on the ethnic group, IVTS are called by a variety of names including, for example, hawala (Middle East, Afghanistan, Indian Sub-Continent); hundi (India); fei ch’ien (飞钱 or "flying money"; China); phoe kuan (Thailand); and Black Market Peso Exchange (South America).
Individuals or groups engaged in operating IVTS may do so on a full-time, part-time, or ad hoc basis. They may work independently, or as part of a multi-person network. IVTS are based on trust. In general, operators usually didn't misappropriate the funds entrusted to them.
The sender gives money to an IVTS agent and his/her counterpart in the receiver region/country acts as deliverer of this money. The sender calls or faxes instructions to his counterpart and the money gets delivered in a matter of few hours. In the past, the message can be delivered using couriers, with men or even animals (such as pigeons). Settlements are made either with a private delivery service or wire transfer in the opposite direction. Another method of balancing the books is to under-invoice goods shipped abroad, so that the receiver can resell the products at a higher market price.
