Letter of Credit (L/C) is a widely used banking document in international trade transactions. For the purpose of banking jargon diversification, some synonyms for the term L/C are as follows: Documentary Credit, Commercial Credit, Bill of Exchange, and Documented Payment. While all these terms have the same underlying meaning, they are often used interchangeably to suit the context of the transaction. In addition to these direct synonyms, further terminology understanding might be helpful for effective trading, including Sight L/C, Revocable L/C, and Irrevocable L/C. Whatever the term used, it remains an essential tool in ensuring payment security and risk mitigation in international trade.
