Hawala Moves Billions Without Crossing a Border or a Bank

A construction worker in Dubai wants to send 500 dirhams to his mother in rural Punjab. He visits a small shop with a hawaladar — a hawala broker. He hands over the cash and is given a code: a six-digit number, sometimes paired with a Quranic phrase or a colored token. He texts the code to his mother. She walks to a hawaladar in her town, recites the code, and is paid out in rupees the same day. No bank wire has moved. No customs form has been filed. The two brokers now owe each other.

The system is at least a thousand years old. Edward Heck's 1921 study of Indian banking documents hundi notes circulating in the same way; the underlying instrument turns up in classical Islamic legal texts as early as the 8th century. The English word check, by some accounts, traces back to the Arabic ṣakk, the same family of bills.

Settlement between hawaladars happens in batches and in many forms — a counter-transfer when funds flow the other way, an over-invoiced shipment of goods, a wire through a corresponding bank account, gold. The flow on the wire never matches the flow of money owed. That is the point. The World Bank has estimated that hawala and similar informal channels handle hundreds of billions of dollars in remittances each year, often the only path into regions where formal banks will not operate.

After 2001, the system attracted attention from regulators worried about terror financing, and the United States designated some operators under sanctions. But hawala has outlasted every effort to absorb it into the formal system. Trust is cheaper than compliance.
