We update it annually as market practice evolves.

PART 1: BASIC INSTRUMENTS

DOCUMENTARY LETTER OF CREDIT (LC)

The documentary letter of credit is the foundational instrument of commodity trade finance, unchanged in essential structure for over two centuries. Under an LC, the buyer's bank (the issuing bank) provides an irrevocable payment undertaking to the seller's bank (the confirming or advising bank), promising to pay the LC amount upon presentation of specified documents that evidence shipment of the contracted goods.

The key documents typically required under commodity trade LCs are the bill of lading (the shipping document that proves the goods have been loaded on board a vessel), the commercial invoice (the seller's demand for payment specifying quantity, price, and terms), the packing list (detailed breakdown of the cargo), and the certificate of origin (evidencing the country of manufacture). Additional documents such as inspection certificates, phytosanitary certificates, or fumigation certificates may be required depending on the commodity and destination.

STANDBY LETTER OF CREDIT

The standby LC is a guarantee instrument rather than a payment mechanism. Under a standby LC, the issuing bank promises to pay the beneficiary if the account party (typically a buyer) fails to meet a specified obligation. Standby LCs are commonly used in commodity trading to guarantee a buyer's payment obligation under an open account arrangement, or to secure a trader's performance obligations under a supply or offtake agreement.

BANK GUARANTEE

Bank guarantees function similarly to standby LCs but are governed by different international rules (URDG rather than UCP 600). They are commonly used in tender processes to evidence bidding capacity (bid bond guarantees) and in contract execution to secure performance (performance guarantees) or advance payment (advance payment guarantees).
