Wa'd

Wa'd is a unilateral promise by one party to do something in the future, such as buy or sell an asset. Islamic finance uses binding promises in hedging and financing where a bilateral forward contract would not be permitted.

Also called: wad · waad · unilateral promise · binding promise · muwa'adah

A sale must happen when it is concluded; Islamic law generally does not allow a binding agreement today to buy and sell at a future date, particularly for currencies. A one-sided promise is treated differently. Many scholars, and AAOIFI's standards, accept that a unilateral promise can be binding on the promisor where the other party has relied on it, while the sale itself is concluded separately when the time comes.

That is the basis of the purchase undertakings in sukuk, the customer's promise to buy in murabaha, and Islamic foreign-exchange hedging. In an Islamic FX "forward", one party promises to exchange currencies at a set rate on a future date and the exchange happens as a spot trade on that date.

Two matching binding promises, one from each side (muwa'adah), are widely viewed as amounting to a forward contract and are usually not accepted for currency exchange.

In practice

A wa'd is not identical to a bilateral sale contract. If both parties are bound to the same future exchange, many scholars treat it as a prohibited forward sale, whatever the documents call it.

Example

An importer must pay €1 million in three months. Its Islamic bank gives a unilateral promise to sell it €1 million at US$1.10 per euro on that date. In three months the two conclude a spot exchange at the promised rate; until then, only the bank is bound.
