A usance draft (or usance bill of exchange) is a trade finance instrument in which the drawee (importer or buyer) is given a specified credit period — typically 30, 60, 90, or 180 days — after the presentation of the bill or after the date of shipment, before payment becomes due. Unlike a sight draft (payable immediately upon presentation), a usance bill creates a short-term credit facility for the buyer — the seller ships the goods, presents the usance bill with shipping documents to the buyer's bank, and the buyer accepts the bill (commits to pay at the future maturity date) before receiving the documents needed to take delivery of the goods. Usance drafts are a cornerstone of international trade finance — particularly in Indian import-export transactions where buyers and sellers have established relationships and the seller is willing to extend trade credit. For Indian exporters, usance bills create a receivable that matures at a future date — this receivable can be discounted by the exporter's bank (bill discounting facility) to obtain immediate working capital against future payment. For Indian importers, usance bills provide a valuable working capital advantage — they can receive, sell, and potentially collect revenue from the imported goods before the bill payment falls due. The RBI regulates usance bill terms for Indian trade — particularly for import transactions, where the maximum usance period for documentary credit is linked to the nature of goods and the exporting country.
