Letter of Credit

A letter of credit is a formal undertaking by an issuer (typically a bank) to honor presentations made under specified terms, paying the beneficiary upon presentation of documents that conform to the credit's requirements. Letters of credit are foundational to international trade and significant in domestic commercial transactions. Two principal types: commercial letters of credit (used as payment mechanism in sale-of-goods transactions, particularly international trade) and standby letters of credit (used as secondary payment guarantee for performance or payment obligations). Texas law governs through UCC Article 5, often supplemented by international rules.

Three-party structure

A typical letter of credit involves three parties: (1) applicant, the party requesting issuance, typically a buyer or contract obligor; (2) issuer, the bank issuing the credit, undertaking the payment obligation; (3) beneficiary, the party entitled to draw on the credit, typically a seller or contract counterparty. Additional parties may include a confirming bank (adding its own undertaking to the issuer's), an advising bank (notifying the beneficiary of the credit's terms), or a nominated bank (authorized to honor or negotiate). The beneficiary's right to draw is independent of the underlying transaction between applicant and beneficiary.

The independence principle

The defining doctrine of letter-of-credit law is the independence principle: the issuer's obligation to honor a conforming presentation is independent of any underlying contract or dispute between the applicant and beneficiary. The issuer pays against documents, not goods or performance, if the beneficiary presents documents that conform to the credit's terms, the issuer must pay, even if the applicant claims that the underlying transaction has been breached. This principle makes letters of credit valuable as payment-certainty instruments. The principle has narrow exceptions for fraud and forgery under § 5.109.

Strict compliance

Issuer payment obligations are gated by strict compliance with the credit's terms, documents must conform precisely to the requirements stated in the credit. The strict-compliance doctrine produces results that may seem hyper-technical: a typographical discrepancy between the credit and the presentation can authorize dishonor. Whether a presentation appears on its face strictly to comply is determined by the standard practice of financial institutions that regularly issue letters of credit, and the issuer's observance of that practice is a matter of interpretation for the court (§ 5.108(a), (e)). Issuers receive a reasonable time (not exceeding seven business days under § 5.108(b)) to honor or to give notice of discrepancies, and an issuer that does not give timely notice of a discrepancy is generally precluded from relying on it (§ 5.108(c)).

Commercial vs. standby distinction

Commercial letters of credit are payment mechanisms, the seller draws against documents (bill of lading, commercial invoice, certificate of inspection) showing performance of the underlying sale, and the issuer pays. The credit is the buyer's primary payment commitment, substituting the issuer's credit for the buyer's. Standby letters of credit are payment guarantees, the beneficiary draws only if the applicant has failed to perform, presenting documents (typically a sworn statement) attesting to the failure. The standby is secondary and contingent, and is functionally similar to a guaranty but structured as an independent payment undertaking.

UCP 600 and ISP98

Letters of credit frequently incorporate one of two international rule sets. UCP 600 (Uniform Customs and Practice for Documentary Credits) is the standard for commercial credits, particularly in international trade. ISP98 (International Standby Practices 1998) is the standard for standby credits. Both rule sets are private contract terms incorporated by reference; where they conflict with Article 5, the incorporated rules govern except as to the nonvariable provisions listed in § 5.103(c) (§ 5.116(c)).

Bankruptcy-remote feature

A critical feature of standby letters of credit is bankruptcy-remoteness: a payment under a letter of credit is from the issuer's funds, not the applicant's. Because the letter of credit and its proceeds are not property of the applicant's estate, the automatic stay under 11 U.S.C. § 362 does not bar a draw, and the issuer's payment is not itself a preferential transfer under § 547. In the Fifth Circuit, though, a beneficiary can be liable for an indirect preference when the credit secures an antecedent debt and the applicant pledged its own assets to the issuer within the preference period (In re Compton Corp., 831 F.2d 586 (5th Cir. 1987)). This makes standby letters of credit attractive as security for landlord lease obligations, surety-type performance bonds, and other commitments where the beneficiary wants insulation from the applicant's bankruptcy risk.
