A letter of credit facility is a pre-approved credit line that lets a business issue multiple letters of credit over a set period without going through separate underwriting for each one. The issuing bank commits to a maximum dollar limit, and the company draws against that limit as trade transactions come up, much like a revolving line of credit dedicated entirely to bank-backed payment guarantees. For importers, contractors, and other businesses that need frequent LCs, the facility replaces one-off applications with predictable, on-demand access.
How the Revolving Limit Works
Every LC facility has a facility limit, the maximum total exposure the bank will carry at one time. Each active letter of credit counts against that limit at its full face value. Request a new LC worth $200,000, and the available capacity drops by $200,000 immediately. Capacity comes back when an LC expires undrawn, when the bank gets reimbursed after honoring a draw, or when the applicant cancels an outstanding credit.
That revolving structure is what separates a facility from a single-transaction LC. A company with a $2 million facility might have six or seven LCs outstanding simultaneously, cycling capacity as shipments arrive and payments settle. The bank monitors utilization continuously and will reject any issuance request that would push total outstanding exposure past the committed limit.
Commercial LCs and Standby LCs
An LC facility can support two very different instruments, and the difference matters because it determines whether the bank expects to pay out.
A commercial LC is the standard tool of international trade. It guarantees payment to a seller once the seller ships goods and presents documents that match the LC’s terms exactly. The bank fully expects to pay on a commercial LC. Payment is the whole point: the buyer uses the LC as the primary payment method, and the seller ships knowing a bank stands behind the obligation.
A standby letter of credit, or SBLC, works the opposite way. It sits in the background as a financial backstop, triggered only if the applicant fails to meet some other obligation, such as repaying a loan, finishing a construction project, or performing under a contract. Under normal circumstances the bank does not expect to pay on an SBLC at all. If one gets drawn, something has already gone wrong. SBLCs are common in domestic transactions, construction bonds, lease guarantees, and any situation where a counterparty wants assurance without the applicant tying up cash.
When you negotiate a facility, be clear about the mix you expect. Some facilities are set up for commercial LCs only, some for standbys only, and some accommodate both under a shared limit.
Getting Approved for an LC Facility
Banks underwrite LC facilities much like any other credit product. The applicant provides financial statements, cash flow projections, and details about its trade operations. The credit team assesses whether the company can reimburse the bank if an LC gets drawn, looking at liquidity, leverage, existing debt obligations, and revenue stability.
Beyond financials, the bank wants to understand how the facility will be used: projected trade volume, typical LC sizes and durations, key trading partners, and the countries involved. Country risk matters, because an LC involving a sanctioned jurisdiction or a politically unstable region changes the bank’s exposure profile significantly.
Once the credit review clears, the bank and applicant negotiate the facility agreement. That document covers the commitment amount, the facility term, financial covenants the borrower must maintain, and the fee structure. Signing it gives the applicant a contractual right to request LC issuances up to the facility limit for the duration of the term.
Sanctions Screening on Every Issuance
Approval of the facility does not clear individual transactions. Every LC issuance triggers a separate compliance review. The Office of Foreign Assets Control (OFAC), housed within the U.S. Department of the Treasury, administers economic and trade sanctions against targeted countries, entities, and individuals. OFAC sanctions can block property, prohibit financial transactions with designated parties, or impose broad trade embargoes on entire countries. Non-U.S. persons face liability too if they cause U.S. persons to violate sanctions or engage in conduct that evades them. Banks screen every LC application against OFAC’s Specially Designated Nationals list, and a hit will delay or kill the transaction regardless of how strong the applicant’s credit is.
Fees, Collateral, and Reimbursement
LC facility costs come in layers. The commitment fee compensates the bank for reserving capacity whether the applicant uses it or not, calculated as an annual percentage of the unused portion of the facility limit. An issuance fee, charged each time an LC goes into effect, runs as a percentage of the LC’s face value prorated for its duration. Typical issuance fees fall in the range of 0.75% to 2% of the transaction amount, though the exact rate depends on the applicant’s creditworthiness, the transaction’s risk profile, and the bank’s competitive posture. Amendments, extensions, and other administrative actions carry their own flat fees, often several hundred dollars each.
Collateral protects the bank against the risk that the applicant cannot reimburse after a draw. The most direct form is a cash margin deposit, where the applicant funds a percentage of the LC’s face value into a segregated account at issuance. That percentage varies widely. Well-established companies with strong credit may deposit as little as 1% of the LC value, while riskier applicants might need to collateralize the full amount. For larger facilities, banks often secure their position with a blanket lien on the applicant’s business assets, perfected through a UCC-1 financing statement filed with the appropriate state office.
When a beneficiary draws on an LC and the bank pays, the applicant’s reimbursement obligation kicks in. That obligation is usually due immediately, though many facility agreements allow the applicant to convert the draw into a short-term loan or banker’s acceptance, spreading repayment over days or weeks in exchange for interest.
As soon as the bank is reimbursed, the corresponding capacity under the facility limit becomes available again. That is the revolving mechanism in action. A company that reimbursed a $300,000 draw on Monday can request a new $300,000 LC on Tuesday, assuming the facility has not expired and no covenants have been tripped. The speed of that cycle is one of the main reasons companies maintain facilities rather than applying for individual credits transaction by transaction.
Issuing an LC Under the Facility
With the facility in place, each individual LC follows a predictable sequence. The applicant submits a request specifying the beneficiary, the amount, the expiration date, and the exact documents required for payment. Those documents typically include a commercial invoice, a packing list, a bill of lading, and sometimes an inspection certificate or insurance policy. The bank confirms the request fits within the available facility limit and issues the credit. The LC is transmitted electronically through the SWIFT network to an advising bank in the beneficiary’s country, which authenticates the message and delivers the terms to the beneficiary. The beneficiary ships the goods, assembles the required documents, and presents them before the LC expires.
Two legal frameworks govern what happens next. The Uniform Customs and Practice for Documentary Credits, published by the International Chamber of Commerce as ICC Publication No. 600, applies to any LC whose text says so, and that covers most commercial LCs worldwide. UCP 600 gives banks a maximum of five banking days after receiving documents to decide whether the presentation complies. In the United States, Article 5 of the Uniform Commercial Code governs LCs as a matter of state law and has been adopted in all 50 states; UCC Section 5-108 gives the bank a reasonable time, no more than seven business days, to honor, accept a draft, or notify the presenter of discrepancies. For standby LCs, the International Standby Practices (ISP98) serve as an alternative to UCP 600, with a three to seven business day examination window and provisions for automatic renewal that UCP 600 does not address.
The Independence Principle
One idea runs through all of these rules and shapes how applicants should think about the product. The LC is legally independent from the underlying deal. UCC Section 5-103 states that the bank’s obligation to the beneficiary is “independent of the existence, performance, or nonperformance” of whatever contract the LC supports. If you and your supplier are fighting over whether goods met specifications, that dispute has no bearing on the bank’s duty to pay against conforming documents. The bank looks at paper, not goods. That independence is what makes the LC valuable to the beneficiary, and it is also why the document-matching exercise is so unforgiving.
Discrepancies
Document discrepancies are extremely common. Estimates from the banking industry suggest that first presentations are rejected more often than they are accepted. Common problems include mismatched descriptions of goods between the invoice and the LC, late shipment dates, missing documents, and port names that do not exactly match the LC terms. Even a misspelled company name can trigger refusal under the strict compliance standard.
When the bank finds discrepancies, it may contact the applicant and offer a chance to waive them. The applicant can agree to accept the documents despite the defects, and if the bank concurs, payment proceeds normally. The bank is never required to seek a waiver, and even if the applicant grants one, the bank keeps discretion to reject the documents anyway.
The Fraud Exception
Independence has one narrow limit. UCC Section 5-109 addresses what happens when a required document is forged or materially fraudulent, or when honoring the presentation would facilitate a material fraud by the beneficiary. Even then, the bank is not automatically excused from paying. If a good-faith purchaser, a confirming bank that already honored its confirmation, or a holder in due course of an accepted draft demands payment, the bank must still honor the presentation. In other cases, the section gives the bank discretion to honor or dishonor in good faith. An applicant who suspects fraud can seek a court injunction to stop payment, but courts grant that relief only if the applicant shows it is “more likely than not to succeed” on its fraud claim, the person demanding payment is not a protected party, and all adversely affected parties are adequately protected against loss. That is a deliberately high bar.
If the Bank Gets It Wrong
If a bank wrongfully refuses to honor a conforming presentation, UCC Section 5-111 gives the beneficiary a right to recover the full amount of the dishonored credit, plus incidental damages. The statute does not allow consequential damages, so lost profits from a collapsed deal are generally not recoverable. The beneficiary has no duty to mitigate. If it does avoid some damages on its own, recovery is reduced accordingly, but the burden of proving that reduction falls on the bank.
The applicant has a separate remedy under the same section. If the bank honors a presentation it should have refused, or otherwise breaches its obligations to the applicant, the applicant can recover resulting damages, again limited to incidental rather than consequential losses. And if the bank misses its examination deadline, Section 5-108 says it is “precluded from asserting as a basis for dishonor any discrepancy” not stated in a timely notice. Those deadlines are worth knowing when a presentation involving your facility runs into trouble.
