Letter of Credit (LC) is a non-fund based facility widely used in trade finance to reduce risks between buyers and sellers. It is a written commitment issued by a bank, guaranteeing that the seller will receive payment once all agreed terms and conditions, such as shipping documents and delivery requirements, are met. The buyer’s bank acts as an intermediary, ensuring security and trust in the transaction. LCs are especially important in international trade, where parties operate across different countries and legal systems. By assuring payment, LCs protect sellers against default risks while giving buyers confidence that goods will be delivered as contracted.
Types Letter of Credits:
-
Revocable Letter of Credit
A revocable Letter of Credit can be amended or canceled by the issuing bank at any time without prior notice to the beneficiary. This type of LC provides flexibility to the buyer but poses significant risk to the seller, as the guarantee of payment may be withdrawn even after shipment of goods. Due to its lack of security for the exporter, revocable LCs are rarely used in modern trade practices. They are suitable only when there is a strong, trusted relationship between the buyer and seller. In most cases, they have been replaced by irrevocable LCs, which provide greater certainty and assurance.
-
Irrevocable Letter of Credit
An irrevocable Letter of Credit cannot be amended or canceled without the agreement of all parties involved — the buyer, seller, and issuing bank. This type of LC provides strong security to the seller, as the issuing bank is legally bound to honor the payment once the stipulated conditions are met. Irrevocable LCs are widely used in international trade because they reduce risks of non-payment and ensure that sellers are protected against sudden changes by the buyer. Since they offer reliability and transparency, these LCs have become the standard practice for global transactions, especially in cross-border trade agreements.
-
Confirmed Letter of Credit
A confirmed Letter of Credit is one where a second bank, usually located in the seller’s country, adds its confirmation to the LC issued by the buyer’s bank. This provides an additional layer of security to the exporter, especially in cases where the buyer’s bank is less known or based in a politically or economically unstable country. The confirming bank guarantees payment if the issuing bank defaults. Although confirmed LCs involve higher costs, they are widely preferred in high-risk trade environments. Exporters benefit from the double assurance, which ensures smooth international transactions and reduced concerns of payment default.
-
Unconfirmed Letter of Credit
An unconfirmed Letter of Credit is guaranteed only by the issuing bank and does not carry the added assurance of a second confirming bank. While this reduces additional costs for the buyer, it also places more risk on the seller, especially in cross-border transactions involving lesser-known banks. Exporters may be cautious when dealing with unconfirmed LCs if they lack trust in the issuing bank’s financial stability. However, these LCs are commonly used in domestic trade or low-risk international transactions. Sellers often seek them when the issuing bank is reputed and reliable, reducing the need for a confirming bank’s involvement.
-
Sight Letter of Credit
A sight Letter of Credit requires the issuing bank to make immediate payment to the seller once the stipulated documents are presented and verified. Sellers benefit from quick access to funds, which helps maintain cash flow. This type of LC is particularly useful in international trade where exporters want immediate payment after shipment without waiting for extended credit periods. Buyers, on the other hand, gain confidence that payment will only be made upon proper shipment and documentation. Sight LCs are highly favored for transactions where sellers need liquidity and prompt settlement to reinvest in their operations or supply chain.
-
Usance (Time) Letter of Credit
A usance or time Letter of Credit provides a deferred payment option, allowing the buyer to make payment after a specified credit period, such as 30, 60, or 90 days from the shipment date or acceptance of documents. This benefits buyers by giving them additional time to sell goods and generate cash flow before settling the obligation. For sellers, the issuing bank’s guarantee ensures eventual payment, reducing risk even though funds are not received immediately. Usance LCs are widely used in trade agreements where buyers require short-term credit facilities. They balance liquidity needs for buyers with security for sellers.
-
Transferable Letter of Credit
A transferable Letter of Credit allows the original beneficiary (seller) to transfer all or part of the credit to a second beneficiary, usually a supplier or subcontractor. This facility is useful in cases where the beneficiary is a middleman or trader rather than the actual producer of goods. It enables smooth supply chain operations, especially in large contracts where multiple suppliers are involved. Transferable LCs save time and cost in arranging multiple financing arrangements. However, they can only be transferred once unless otherwise specified. They provide flexibility for beneficiaries while maintaining assurance of payment for both parties involved.
-
Back–to–Back Letter of Credit
A back-to-back Letter of Credit involves two separate LCs: one issued in favor of an intermediary (such as a trader) and another issued by the intermediary’s bank in favor of the actual supplier. This arrangement is commonly used in international trade where intermediaries play a significant role. The first LC provides security to the trader, while the second LC ensures payment to the supplier. It helps middlemen fulfill large orders without requiring significant upfront capital. While beneficial, back-to-back LCs involve higher administrative costs and require careful management to ensure all conditions are met in both credit arrangements.
Advantages of Letters of Credit:
-
Security for Sellers
The greatest advantage of a Letter of Credit is the security it provides to exporters or sellers. Payment is guaranteed by the issuing bank once the seller fulfills the terms and presents compliant documents, such as shipping invoices and bills of lading. This minimizes the risk of buyer default or refusal to pay, especially in international trade where parties may not know each other. Sellers can confidently ship goods, knowing they will be paid promptly if they meet contractual requirements. By removing uncertainties, LCs give sellers financial stability, improve cash flow, and reduce the chances of financial disputes with buyers.
-
Trust in International Trade
Letters of Credit are crucial in global trade where buyers and sellers are separated by geography, laws, and cultures. They bridge trust gaps by making the bank an intermediary that guarantees payment upon compliance with agreed conditions. Buyers gain assurance that goods will be shipped as contracted, while sellers are assured of receiving payment. This mutual trust encourages smoother trade between unfamiliar parties. LCs also reduce political, currency, and credit risks in cross-border transactions. By creating transparency, they promote international business growth, allowing companies to expand globally while ensuring that both sides are financially protected and mutually accountable.
-
Flexibility in Payment Terms
LCs offer flexibility to both buyers and sellers through different forms, such as sight LCs (immediate payment) and usance LCs (deferred payment). Buyers can negotiate credit periods, giving them time to sell goods and generate revenue before making payments, while sellers enjoy security from the bank’s guarantee. Transferable and back-to-back LCs also facilitate supply chain arrangements, enabling intermediaries and subcontractors to participate in large deals. This adaptability makes LCs suitable for various industries and transaction sizes. The ability to customize payment terms enhances convenience, balances the needs of both parties, and ensures financial efficiency in global business contracts.
-
Risk Mitigation for All Parties
Letters of Credit significantly mitigate risks for both buyers and sellers. For sellers, it ensures payment once conditions are met, while buyers are protected from paying for goods not shipped or improperly documented. Banks, acting as trusted intermediaries, also minimize risks related to fraud, default, and non-performance. In addition, LCs reduce exposure to foreign exchange fluctuations and political instability, especially in international markets. By clearly defining obligations and conditions, LCs create a structured framework that limits disputes. This risk-sharing mechanism strengthens business relationships, improves reliability, and makes LCs one of the safest instruments for securing high-value commercial transactions.
Limitations of Letters of Credit:
-
High Cost of Operation
One of the main limitations of Letters of Credit is their high operational cost. Banks charge fees for issuing, advising, confirming, and negotiating LCs, which can be significant for small and medium-sized businesses. Additional charges may apply for document verification, amendments, or discrepancies. These costs increase the overall transaction expense, making LCs less attractive for low-margin deals. For exporters or importers with limited financial capacity, the expenses can outweigh the benefits. Moreover, in competitive markets, these added costs may reduce profit margins and price competitiveness. Thus, while LCs provide security, they can financially burden parties, especially smaller firms engaged in international trade.
-
Complexity in Documentation
Letters of Credit involve strict compliance with documentary requirements. Banks only deal with documents, not the actual goods, meaning even minor errors or inconsistencies in invoices, shipping bills, or certificates can result in non-payment. This makes the process highly technical and often requires professional assistance. Exporters, particularly those new to international trade, may find it challenging to prepare error-free documents. The rigid scrutiny delays payment and may lead to rejection, causing financial stress. Additionally, amending LCs to correct mistakes takes time and incurs extra costs. Hence, the complexity and paperwork involved in LCs reduce their ease of use.
-
Limited Flexibility
Although LCs provide security, they can lack flexibility once issued. Terms and conditions are binding, and any modification requires the consent of all parties, along with additional bank charges. This rigidity can be problematic in dynamic trade environments where circumstances such as shipping delays, product modifications, or regulatory changes require adjustments. Buyers and sellers may face disputes if the LC does not fully align with the evolving needs of the transaction. In addition, once terms are set, sellers must adhere strictly, even if conditions become unfavorable. Therefore, the limited adaptability of LCs may reduce convenience in certain trade situations.
-
Risk of Fraud and Misuse
Despite bank involvement, Letters of Credit are not completely free from risks of fraud or misuse. Since banks deal only with documents, they cannot verify the actual quality or quantity of goods shipped. Fraudulent exporters may present falsified documents and still receive payment. Similarly, buyers may collude with third parties to create disputes over compliance. The reliance on paperwork makes LCs vulnerable in cases of forgery or misrepresentation. While additional measures such as inspection certificates can help, they increase cost and time. Thus, the risk of fraud, though reduced, cannot be fully eliminated, posing a limitation to LCs.
Types of Risks in Letters of Credit:
-
Commercial Risk
Commercial risk in Letters of Credit arises from the financial inability or unwillingness of the buyer or seller to fulfill obligations. For example, an importer may default on payment despite the LC arrangement, or an exporter may fail to deliver goods of agreed quality and quantity. While banks provide a level of security, disputes over goods, late shipment, or incorrect documents can lead to non-payment. This risk is heightened in unstable business relationships, where trust is limited. Even though LCs reduce counterparty risk, they cannot fully guarantee the commercial performance of trade. Thus, buyers and sellers must exercise due diligence and establish reliable trade partnerships.
-
Country / Political Risk
Country or political risk occurs when external factors such as political instability, wars, sanctions, or changes in government policies disrupt LC transactions. Even if both buyer and seller are willing to perform, trade restrictions, foreign exchange shortages, or embargoes can prevent payment. For instance, in countries facing economic crises, banks may be unable to remit foreign currency to honor LCs. Similarly, sudden regulatory changes may invalidate previously agreed terms. Such risks are beyond the control of the trading parties, making LCs vulnerable in cross-border dealings. To mitigate, exporters often seek confirmed LCs from reputable banks in politically stable nations.
-
Operational Risk
Operational risk in LCs refers to errors, delays, or failures in banking processes, documentation, or communication. Since LCs are heavily dependent on precise paperwork, even small discrepancies—like spelling mistakes, mismatched figures, or missing documents—can cause rejection or delayed payment. Banks deal only with documents and not with goods, making the system vulnerable to technical issues or clerical mistakes. Additionally, delays in courier services, SWIFT errors, or miscommunication between banks across countries may further complicate matters. These operational inefficiencies can harm trust and liquidity. Proper training, digital systems, and attention to detail are essential to minimize operational risks in LCs.
-
Foreign Exchange Risk
Foreign exchange risk arises because Letters of Credit usually involve multiple currencies in international trade. The value of payment may fluctuate between the date of contract and the actual settlement due to exchange rate volatility. For instance, an exporter expecting USD may suffer losses if the dollar depreciates significantly against the local currency before payment. Similarly, importers may face higher costs if their currency weakens. While banks may offer hedging options like forward contracts, not all businesses utilize them effectively. Thus, currency fluctuations pose significant uncertainty in LC transactions, especially for long-term or high-value deals, affecting profitability and planning.
Assessment of LC limits:
-
Financial Assessment
The financial assessment of LC limits evaluates the applicant’s financial health and repayment capacity. Banks review audited financial statements, profitability, liquidity, and leverage ratios to ensure the customer has a stable position. Cash flows, working capital cycle, and past repayment records are closely examined to determine if the business can meet payment obligations under the LC. A strong balance sheet and consistent earnings support higher limits, while weak performance results in stricter terms. The bank also examines the applicant’s credit history, banking relationships, and existing exposure levels. This financial scrutiny helps minimize default risks and ensures that LC limits are allocated prudently.
-
Business and Trade Assessment
Business and trade assessment of LC limits focuses on the applicant’s industry position, trading patterns, and reliability in international markets. Banks evaluate the nature of goods being traded, market demand, and potential risks associated with the product or region. Past trade records, shipment history, and relationships with overseas buyers and suppliers are analyzed to assess credibility. The consistency of trade volumes and diversification of markets are also important, as overdependence on a single buyer or country increases risk. By assessing the trade profile, banks ensure LC limits are extended only to genuine, reliable, and growth-oriented businesses with sustainable international dealings.
-
Risk Assessment
Risk assessment of LC limits involves evaluating potential risks in transactions, including commercial, operational, political, and foreign exchange risks. Banks assess the applicant’s exposure to volatile markets, unstable currencies, and high-risk countries. They also examine documentation practices and past discrepancies in LC operations, as weak compliance can result in non-payment. Insurance coverage, such as export credit insurance, is also considered to reduce risks. Additionally, banks assess whether the applicant’s transactions align with regulatory norms and anti-money laundering guidelines. By carefully analyzing these risk factors, banks determine the appropriate LC limit that balances trade facilitation with financial security, ensuring stability.
Process of Fixing LC Limits:
-
Submission of Application and Documents
The process begins when the applicant submits a formal request for LC limits along with required documents. These usually include audited financial statements, income tax returns, details of trade transactions, projected sales, and information on overseas buyers or suppliers. The bank also requires past records of trade bills, repayment history, and details of existing credit facilities. A comprehensive KYC (Know Your Customer) compliance is conducted to verify the applicant’s identity and business legitimacy. This documentation serves as the foundation for evaluating financial strength and trade potential. Proper submission ensures faster processing and helps the bank gain clarity about the applicant’s credibility and repayment ability.
- Creditworthiness and Risk Evaluation
Once documents are received, the bank conducts a detailed creditworthiness assessment. Financial ratios such as current ratio, debt-equity ratio, and interest coverage ratio are analyzed to gauge repayment capacity. The bank also checks the applicant’s credit rating, repayment track record, and existing loan obligations. Trade risks like country exposure, product risk, and foreign exchange volatility are also evaluated. Compliance with regulatory requirements and international trade norms is verified to avoid future disputes. Risk mitigation measures such as collateral or guarantees may be demanded depending on exposure levels. This step ensures that LC limits are fixed in line with the applicant’s financial soundness and trade reliability.
-
Determination of Limit Size and Terms
Based on the applicant’s financial strength, business volume, and risk profile, the bank decides the quantum of LC limits to be sanctioned. The limit is fixed to match the genuine trade requirements, avoiding both under-financing and over-exposure. Terms and conditions such as margin requirements, validity period, collateral security, and applicable charges are clearly defined. The bank also specifies the nature of goods covered, permissible countries, and adherence to foreign trade regulations. This structured approach ensures that limits are sufficient to facilitate trade while safeguarding the bank’s interests. Transparent terms help maintain accountability and smooth execution of LC transactions.
-
Sanction, Documentation, and Monitoring
After fixing the LC limit, the bank issues a formal sanction letter outlining approved limits and conditions. The applicant must complete necessary legal and security documentation, such as hypothecation agreements, guarantees, or lien on collateral. Once documentation is executed, the limits are activated for trade transactions. The bank continuously monitors the utilization of LC limits, repayment discipline, and adherence to terms. Periodic reviews are conducted to revise or renew the limits based on updated financials and trade performance. This ensures effective risk control, compliance with regulations, and sustainability of trade financing through Letters of Credit.
