Margin

In foreign trade terminology, Margin generally refers to a certain percentage of funds that the buyer deposits with a bank or counterparty when opening a letter of credit, signing a contract, or engaging in derivatives transactions, as a guarantee for fulfilling obligations. It is commonly seen in letter of credit business (such as L/C margin), foreign exchange forward/futures transactions (initial margin, maintenance margin), and commodity trading. Usage scenarios include: when an importer applies for an L/C, the bank requires a deposit of a certain percentage of the L/C amount as margin to reduce risk; exporters provide margin when bidding or performing contracts. Notes: The margin ratio varies depending on the bank, customer credit, and commodity volatility, and may range from 0% to 100%; if the market moves adversely, a margin call may be required, otherwise the position will be forcibly liquidated. Unlike a 'deposit', margin emphasizes guarantee and performance assurance in leveraged transactions, and may be adjusted due to price fluctuations; unlike a 'down payment', margin is usually refundable or deductible, but may be forfeited upon default. Foreign trade practitioners need to clarify margin terms to avoid capital chain risks.
