Letters of Credit in 2025: The Ultimate Guide to Digital LCs, Blockchain and Compliance

Discover the latest trends, tools, and best practices in LC transactions for 2025. Ideal for exporters, importers, bankers, and trade finance professionals.

What Is a Letter of Credit (LC) in 2025?

A Letter of Credit (LC) is a bank-guaranteed payment mechanism that ensures payment to the seller upon submission of compliant documents.

Key Parties Involved

• Applicant (Buyer): Requests the LC.
• Beneficiary (Seller): Receives payment.
• Issuing Bank: Guarantees payment.
• Advising Bank: Verifies documents.
• Confirming Bank (Optional): Adds payment guarantee.

Why LCs Remain Popular in 2025

• Minimizes cross-border payment risk
• Enhances trade trust and reliability
• Adapts to digital finance and blockchain trends

Latest Trends in LC Transactions (2025 Updates)

A. Digital LCs & Blockchain Adoption

• 100% digital LC issuance via SWIFT MT700
• Blockchain platforms (Contour, Marco Polo) reduce processing time to 24 hrs Blockchain and Letters of Credit (LCs): A New Era of Trust and Speed in Global Trade Blockchain technology is transforming how Letters of Credit (LCs) work in international trade. Traditionally, LCs involved piles of paperwork, long processing times, and high chances of errors or fraud. But in 2025, digital LCs powered by blockchain offer a faster, more secure, and transparent alternative. Smart contracts automate terms between buyers, sellers, and banks—minimizing human error and reducing delays. Every step of the transaction, from document verification to payment release, is recorded in real time on a tamper-proof digital ledger. This not only improves trust among all parties but also helps businesses lower costs, comply with trade regulations, and avoid common LC discrepancies. As more banks and trading companies adopt blockchain-based LCs, global trade is entering a new era of efficiency and digital innovation.
• Smart contracts trigger payments automatically

B. ESG (Environmental, Social, Governance) LCs

• Sustainable clauses in LCs (carbon-neutral shipping)
• Discounts on eco-friendly LC transactions

C. Geopolitical Risks & Sanctions Compliance

Reimbursement undertaking

 

What is a Reimbursement Undertaking?

A reimbursement undertaking is issued by a reimbursing bank at the request of an issuing bank, in favor of a claiming bank—typically the confirming bank—to honor that bank's reimbursement claim. It's important to note that this undertaking is not issued in favor of the beneficiary of the letter of credit (L/C). From the beneficiary's perspective, such an undertaking is generally not essential for his own bank to process or handle the credit.

However, in trade finance practices, banks that are reluctant to confirm an L/C due to country risk or the creditworthiness of the issuing bank may request a reimbursement undertaking. This instrument helps mitigate risk and provides assurance that reimbursement will be honored, thereby securing the confirming bank’s exposure.

Often, exporters or beneficiaries require the credit to be confirmed—particularly when the issuing bank is located in a high-risk country or has a low credit rating. But suppose the nominated bank (usually the exporter’s bank) lacks a credit limit or country exposure limit to take on the risk of such an issuing bank or jurisdiction. In that case, it may request the risk to be shifted to the reimbursing bank, often based in a more stable financial environment.

In such cases, the nominated or confirming bank may request an Irrevocable Reimbursement Undertaking (IRU) from the reimbursing bank, located in a safer jurisdiction where it has available limits. It’s crucial to understand that the reimbursing bank, when issuing such an IRU, is not concerned with the documentary compliance of the beneficiary’s presentation, but only with the validity of the claiming bank’s demand.

According to Article 1 of URR 725 (Uniform Rules for Bank-to-Bank Reimbursements), in a bank-to-bank reimbursement, the reimbursing bank acts solely on the instructions and under the authority of the issuing bank.

Further, Article 2 defines a Reimbursement Undertaking as a separate, irrevocable undertaking issued by the reimbursing bank upon the authorization or request of the issuing bank, addressed to the claiming bank. This obligates the reimbursing bank to honor the claim as long as the terms and conditions of the reimbursement undertaking are complied with.

Therefore, a reimbursing bank cannot issue an IRU without the explicit instruction from the issuing bank. This reinforces that an IRU is not an independent instrument like a standby letter of credit, but rather part of the structured reimbursement arrangement tied directly to the issuing bank's authority.

A Reimbursement Undertaking is a commitment by a reimbursing bank—often instructed by the issuing bank—to honor claims made by a nominated or confirming bank under a letter of credit (LC). It is not issued in favor of the beneficiary, and from the beneficiary’s point of view, it is generally not necessary for handling the LC.

Why Reimbursement Undertakings Are Used

In trade finance, some confirming banks are hesitant to confirm LCs due to:

• Country risk
• Issuing bank creditworthiness

To reduce their exposure, they may request an Irrevocable Reimbursement Undertaking (IRU) from a reimbursing bank in a more stable jurisdiction.

Key Benefits

• Shifts risk from confirming bank to reimbursing bank
• Enables exporters to receive payment promptly
• Improves confidence in LCs involving high-risk issuing banks

How It Works

1. The issuing bank instructs a reimbursing bank to issue a reimbursement undertaking.
2. The confirming/nominated bank pays the beneficiary.
3. The confirming bank submits a claim to the reimbursing bank.
4. The reimbursing bank honors the claim if terms are met.

Legal Foundation: UCP 600 & URR 725

• URR 725 Article 1: Reimbursing bank acts solely under issuing bank’s instructions.
• URR 725 Article 2: Reimbursement undertaking is a separate, irrevocable instrument in favor of the claiming bank (not the beneficiary).
• It is not concerned with document compliance by the beneficiary, only the validity of the claim by the claiming bank.

2025 Update

• No changes to UCP 600 (still the 2007 version).
• eUCP updated to v2.1 in 2023 for electronic LCs (not affecting reimbursement undertakings).
• Incoterms^® 2020 still in effect; no 2025 version released.
• Digital LC platforms (e.g., Contour, Marco Polo) gaining traction—but traditional rules still apply unless otherwise agreed.

Summary

The Reimbursement Undertaking is a crucial risk-mitigation tool in letter of credit transactions, especially for confirming banks handling LCs issued from higher-risk jurisdictions. Although digital trends are emerging, as of 2025, the core rules under UCP 600 and URR 725 remain unchanged.
