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 business draws against that limit as deals come up, much like a revolving line of credit dedicated entirely to trade guarantees. For companies that import regularly or need ongoing performance guarantees, the facility replaces one-off applications with predictable, on-demand access to bank-backed payment assurances.
How the Revolving Limit Works
The core of any facility is the facility limit, the maximum total exposure the bank will carry at one time. Every active letter of credit counts against that limit at its full face value. Request a new $200,000 credit and the available capacity drops by $200,000 immediately. Capacity comes back when a credit expires without being drawn, when the bank gets reimbursed after honoring a draw, or when the business cancels an outstanding credit.
That revolving structure is what separates a facility from a one-off credit. A company with a $2 million facility might have six or seven credits outstanding at once, cycling capacity as shipments arrive and payments settle. The bank monitors utilization continuously and will reject any issuance request that would push total exposure past the committed limit.
Commercial Credits vs. Standby Credits
A facility can issue two fundamentally different instruments, and the distinction matters because it determines when the bank expects to pay out money.
A commercial letter of credit is the workhorse of international trade. It guarantees payment to a seller once the seller ships goods and presents documents that match the credit’s terms exactly. The bank fully expects to pay, because payment is the point. The buyer uses the credit as the primary payment method, and the seller ships with confidence knowing a bank stands behind the obligation.
A standby letter of credit (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, like repaying a loan, finishing a construction project, or delivering on a contract. The bank does not expect to pay on an SBLC under normal circumstances. If one gets drawn, something has already gone wrong. SBLCs are common in domestic transactions, construction bonds, lease guarantees, and anywhere a counterparty wants assurance without tying up cash.
Getting Approved for a Facility
Banks underwrite letter of credit facilities much like any other credit product. The applicant provides financial statements, cash flow projections, and details about its trade operations. The credit team looks at whether the company can reimburse the bank if a credit gets drawn, weighing liquidity, leverage, existing debt obligations, and the stability of revenue.
Beyond the financials, the bank wants to understand how the facility will be used: projected trade volume, typical credit sizes and durations, key trading partners, and the countries involved. Country risk matters, because a credit involving a sanctioned jurisdiction or politically unstable region changes the bank’s exposure profile significantly.
Once credit review clears, the bank and applicant negotiate the facility agreement, covering the commitment amount, the term, financial covenants the borrower must maintain, and the fee structure. The executed agreement gives the applicant a contractual right to request issuances up to the limit for the duration of the term.
Sanctions Screening
Every issuance under the facility triggers a 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 also face liability if they cause U.S. persons to violate sanctions or engage in evasive conduct. Banks screen every 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
Facility costs come in several layers. The commitment fee compensates the bank for reserving capacity whether or not the applicant uses it, calculated as an annual percentage of the unused portion of the limit. The issuance fee, charged each time a credit goes into effect, is a percentage of the credit’s face value prorated for its duration. Typical issuance fees fall in the range of 0.75% to 2% of the transaction amount, with the exact rate depending on the applicant’s creditworthiness, the transaction’s risk profile, and the bank’s competitive posture. Amendments, extensions, and other administrative actions carry flat fees, often several hundred dollars each.
If a beneficiary draws on a credit, the applicant must reimburse the issuing bank. That obligation is usually due immediately, though many facility agreements let the applicant convert the draw into a short-term loan or banker’s acceptance, spreading repayment over days or weeks in exchange for interest.
Banks require collateral to protect against the risk that an applicant cannot reimburse after a draw. The most direct form is a cash margin deposit, where the applicant puts a percentage of the credit’s face value into a segregated account at issuance. The required percentage varies widely based on credit history and financial strength. Well-established companies with strong credit may deposit as little as 1% of the credit value, while riskier applicants might need to collateralize the full amount. For larger facilities, banks often secure their position with a blanket lien on business assets, perfected through a UCC-1 financing statement filed with the appropriate state office.
As soon as the bank is reimbursed, the corresponding capacity opens back up. A company that reimbursed a $300,000 draw on Monday can request a new $300,000 credit on Tuesday, assuming the facility has not expired and no covenant violations have occurred. That speed is one of the main reasons companies maintain facilities instead of applying for credits one transaction at a time.
Issuing a Credit Under the Facility
With the facility in place, issuing an individual credit follows a predictable sequence. The applicant submits a request specifying the beneficiary, the amount, the expiration date, and the exact documents required for payment, typically a commercial invoice, packing list, bill of lading, and sometimes an inspection certificate or insurance policy. The bank confirms the request fits within the available limit and issues the credit. The advising bank in the beneficiary’s country authenticates the message and delivers the terms to the beneficiary. The beneficiary ships the goods, assembles the required documents, and presents them to the advising or nominated bank before the credit expires.
When the Beneficiary Wants a Second Bank on the Hook
If a beneficiary is uncomfortable with the issuing bank’s creditworthiness or the political risk of the buyer’s country, it can ask for the credit to be confirmed. A confirming bank, usually located in the beneficiary’s country, adds its own independent payment obligation on top of the issuing bank’s commitment. The beneficiary now has two banks obligated to pay, insulating it from both credit risk and country risk on the issuing bank’s side. Confirmation adds cost, but for exporters dealing with unfamiliar banks in high-risk markets, it is often the only way to get comfortable shipping on credit terms.
When Documents Don’t Match
Document examination is where most transactions get complicated. The bank’s job when documents arrive is purely mechanical: do the documents, on their face, match what the credit requires? The bank does not inspect goods, verify that a shipment actually occurred, or resolve factual disputes between buyer and seller. Under UCC Section 5-108, the standard is strict facial compliance, judged against the practices of financial institutions that regularly issue letters of credit.
Discrepancies are extremely common. Estimates from the banking industry suggest first presentations are rejected more often than they are accepted. Typical problems include mismatched descriptions of goods between the invoice and the credit, late shipment dates, missing documents, and port names that do not exactly match the terms. Even a misspelled company name can trigger a refusal under the strict compliance standard.
When the bank finds discrepancies, it may contact the applicant and offer the 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, though, and even if the applicant grants one, the bank retains discretion to reject anyway. The safer approach is getting the documents right the first time, which is why experienced trade finance teams review documents internally before presenting them to the bank.
The Rules That Govern Payment
Two bodies of rules govern virtually all letter of credit transactions, and they dictate how banks examine documents, when payment is required, and what happens when things go wrong.
UCP 600
The Uniform Customs and Practice for Documentary Credits, published by the International Chamber of Commerce as ICC Publication No. 600, applies to any credit whose text states it is subject to these rules. In practice, that covers most commercial credits worldwide. UCP 600 gives banks a maximum of five banking days after receiving documents to decide whether a presentation complies. If the bank finds discrepancies, it must send a refusal notice by the end of that five-day window or lose the right to reject.
UCC Article 5
In the United States, Article 5 of the Uniform Commercial Code governs letters of credit as a matter of state law, adopted in all 50 states. UCC Section 5-108 requires the issuing bank to honor any presentation that “appears on its face strictly to comply with the terms and conditions of the letter of credit,” and to dishonor any presentation that does not. The bank gets a reasonable time after receiving documents, but no more than seven business days, to honor, accept a draft, or notify the presenter of discrepancies. A bank that misses that window is “precluded from asserting as a basis for dishonor any discrepancy” not stated in the notice.
For standby letters of credit, the International Standby Practices (ISP98) serve as an alternative to UCP 600, tailored specifically to standby mechanics.
The Independence Principle
One concept runs through both frameworks: the credit 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 credit supports. If the buyer and seller are fighting over whether the 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 instrument valuable, because the beneficiary’s right to payment depends solely on presenting the right documents, not on resolving commercial disagreements.
The Fraud Exception
Independence has one narrow exception. 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 issuing bank is not automatically excused from paying. A good-faith purchaser, a confirming bank that already honored its confirmation, or a holder in due course of an accepted draft must still be paid despite the fraud. In other cases, Section 5-109 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 set a deliberately high bar, because the entire system depends on banks paying reliably and quickly.
When a Bank Gets It Wrong
If a bank wrongfully refuses to honor a conforming presentation, UCC Section 5-111 gives the beneficiary the 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 deal that fell apart because payment was refused are generally not recoverable. The applicant has a parallel remedy: 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 losses.
