A bank's written promise to pay an exporter once it presents shipping documents that match the credit's terms exactly.
See it on the Money & Finance map →How it works
A Los Angeles importer asks its bank to issue a credit naming a supplier in Busan. The supplier ships, then gives its bank the bill of lading, invoice, insurance certificate and other listed papers. Banks examine documents, not goods, within five banking days; if they comply, the issuing bank must pay. A 'confirmed' LC adds a second bank's promise, usually in the exporter's country, in case the issuing bank or its country fails. Fees often total about 0.5–2%.
Why it matters
It swaps the buyer's credit risk for a bank's, so strangers in different legal systems can trade large sums. The catch: small errors in the papers let the bank refuse to pay.
Think of it like
Like a tenant-improvement allowance paid only when the contractor delivers invoices and lien releases: the paperwork, not the work itself, triggers payment.
Facts, rules and data
The ICC's UCP 600 rules (in force July 1, 2007), UCC Article 5, court cases on strict compliance, and SWIFT data on LC messages; industry surveys often find half or more of first presentations discrepant.
Debates and risks
Why LC use keeps shrinking in favor of open account, and whether electronic bills of lading and digital documents can make LCs cheaper and faster.
Connections (6)
▸Commercial letters of credit (UCP 600) and confirmed LCs fall under Article 5 of Uniform Commercial Code rules for checks, wires and LCsFact, law or data
The connection
Most international LCs say they follow the ICC's UCP 600, but US law still governs where those rules are silent. Article 5 sets the independence principle (the bank's promise stands apart from the sales contract), a maximum of seven business days to examine documents, and a narrow fraud exception that lets a court halt payment.
When and why
Revised Article 5 approved in 1995 and adopted by the states, building on cases such as Sztejn v. J. Henry Schroder Banking Corp. (New York, 1941).
How we know
UCC sections 5-103, 5-108 and 5-109, and the Sztejn case, where a seller shipped rubbish instead of the bristles ordered.
Debates and risks
How strict 'strict compliance' should be: courts and banks keep disputing whether small typos in documents justify refusing payment.
▸Commercial letters of credit (UCP 600) and confirmed LCs sit between prepayment and open account in Trade finance and payment guarantees: getting paid safelyFact, law or data
The connection
Exporters and importers face opposite risks. Cash in advance protects the exporter; open account, ship now and invoice later, protects the importer. A letter of credit sits between: the importer pays only once documents show shipment, and the exporter is paid by a bank once it proves shipment, whatever the buyer's finances.
When and why
Used worldwide for centuries in some form; most common today in trade with Asia, the Middle East and emerging markets.
How we know
The US Commerce Department's Trade Finance Guide ranks the methods by risk; ICC trade-finance surveys track LC use.
Debates and risks
Why LC volumes keep falling while open account dominates, often estimated at about 80% of trade, and whether that leaves small exporters underserved.
▸Commercial letters of credit (UCP 600) and confirmed LCs pay against presentation of Bills of lading: the shipping document that controls the goodsFact, law or data
The connection
The exporter is paid only when it presents a clean, on-board bill of lading, usually made out to the order of the issuing bank, along with the other listed papers. The bank thus controls the goods until the importer reimburses it, and the dates and ports on the bill must match the credit.
When and why
In LC payments worldwide; UCP 600 article 20 sets what a bank checks on a bill of lading.
How we know
UCP 600 articles 14 and 20, ICC banking opinions, and court cases where late or 'claused' bills led banks to refuse payment.
Debates and risks
Whether electronic bills of lading under the ICC's eUCP rules will end paper delays, since originals often arrive after the ship.
▸Standby letters of credit and bank guarantees pay only on default, unlike Commercial letters of credit (UCP 600) and confirmed LCsFact, law or data
The connection
A commercial LC is the planned way to pay: the bank pays when shipping documents arrive. A standby is a backstop: the bank pays only if its customer fails, against a demand stating default. Both stand apart from the underlying deal, but most standbys are never drawn, while commercial LCs nearly always are.
When and why
Standbys spread in US banking from the 1970s because national banks generally could not issue guarantees; ISP98 rules followed in 1998.
How we know
Bank capital rules (Basel conversion factors: 20% for short-term trade LCs, 50% or 100% for standbys), ISP98 and UCP 600.
Debates and risks
How much standby exposure banks carry off balance sheet in a downturn, when many are drawn at once, is hard to see from outside.
▸Incoterms: who pays freight and when risk passes must match the documents in Commercial letters of credit (UCP 600) and confirmed LCsFact, law or data
The connection
The LC names the Incoterm, and the documents must fit it. Under 'CIF Los Angeles', the exporter must present an insurance certificate and a 'freight prepaid' bill of lading; under FOB, freight is normally collect and no insurance document is needed. A mismatch is a discrepancy the bank can reject.
When and why
In LC transactions worldwide; UCP 600's articles on transport and insurance documents apply alongside the chosen term.
How we know
ICC banking opinions and UCP 600 articles 20 and 28, which set what bills of lading and insurance documents must show.
Debates and risks
Why traders still use FOB and CIF for container shipments, where the ICC advises FCA or CIP, and how often that causes disputes.
▸Commercial banks: taking deposits, making loans issue and pay Commercial letters of credit (UCP 600) and confirmed LCsFact, law or data
The connection
The importer's bank issues the credit as a loan-like exposure: it checks the importer's credit, often requires a credit line or cash collateral, and charges fees. Other banks advise, confirm or pay. Regulators treat the promise as an off-balance-sheet commitment that needs capital, though less than a loan.
When and why
Large trade banks such as HSBC, Citi, JPMorgan, Standard Chartered and Korea's Hana Bank are leading issuers; many US community banks issue domestic standbys.
How we know
Bank call reports listing letters of credit outstanding, Basel capital rules, and ICC Banking Commission trade surveys.
Debates and risks
Whether rising capital and compliance costs push banks out of trade finance for small firms and poorer countries.
