Letter of credit

A bank's promise to pay the exporter once documents are presented. Security, at a cost.

What it means

A documentary letter of credit is an undertaking by the buyer's bank to pay the seller against presentation of specified documents.

Why it matters

It transfers the credit risk from an unknown overseas buyer to a bank, which is why it is used where the parties do not know each other.

What it looks like in practice

Payment depends on the DOCUMENTS being exactly right, not on the goods being right. Discrepancies are the norm, and a discrepant presentation can be refused.

What to watch out for

Small documentary errors — a spelling, a date, a missing signature — which defeat presentation. Check the terms against what you can actually produce before accepting one.

Where to get proper advice

An FCA-regulated broker, and your bank. Compare the total cost including the spread, not the headline fee. And a trade finance specialist at your bank.
