Red clause letters of credit originated as a means of providing sellers financing for purchases or production of goods. They allowed sellers to receive advances from the issuing or confirming bank before shipment using the letter of credit as collateral. While once common, red clause credits are now rarely used, being largely replaced by other forms of financing. Recent cases discuss liability and remedies under these historical letters of credit, but they remain mostly a thing of the past, confined now to only occasional or niche uses.
