Demystifying Documentary LCs

Image
  Imagine you're ordering a fancy bike online from a foreign company. You wouldn't just send them money and hope they send you the bike, right? That's where a Documentary Letter of Credit (LC) comes in. It's like a super secure handshake for international trade, with documents acting as the middleman. Here's how it works: You (the buyer):  Open an LC with your bank (the issuing bank). This is like a promise from your bank to pay the seller (the beneficiary) if they do their part. The LC outlines specific requirements:  What documents the seller needs to provide (e.g., shipping bill, inspection certificate) and what the goods should be like (e.g., brand, model, color). Your bank sends the LC to the seller's bank (the advising bank) . This bank informs the seller about the LC and its conditions. The seller ships the bike and gathers all the required documents. Think of it as collecting evidence. The seller presents the documents to their bank. The bank checks...
