# Understanding Back-to-Back Letters of Credit in International Trade

## What Are Back-to-Back Letters of Credit?

Back-to-back letters of credit play a crucial role in international trade by using two separate letters of credit to facilitate transactions involving an intermediary. The first letter of credit acts as collateral for the second, providing financial assurance in situations where verifying creditworthiness may be challenging. This mechanism safeguards both parties by using bank credit, ensuring payment upon contract terms fulfillment, and simplifying complex international deals.

### Key Takeaways

*   Back-to-back letters of credit involve two separate letters of credit used in international transactions to ensure payment.  
    
*   These instruments provide financial protection by leveraging the creditworthiness of banks instead of the trading parties.  
    
*   The first letter of credit serves as collateral for the second, facilitating transactions with intermediaries like brokers.  
    
*   They are especially useful when parties have difficulty verifying each other’s creditworthiness.  
    
*   Despite their benefits, banks generally discourage their use due to the complexity and potential risks involved.

## Understanding the Mechanics of Back-to-Back Letters of Credit

Back-to-back letters of credit are made up of two different letters of credit, with a first one spurring the creation of the second.

With a back-to-back letter of credit, the buyer's [bank](https://www.investopedia.com/articles/investing/060915/which-are-top-10-private-banks.asp) issues one letter of credit to the intermediary or broker. The intermediary's bank issues the other letter of credit to the seller. With the original letter of credit from the buyer's bank in place, the broker goes to his own bank and has a second LoC issued, with the seller as the [beneficiary](https://www.investopedia.com/terms/b/beneficiary.asp).

The seller is assured of payment upon fulfilling the terms of the contract and presenting the appropriate documentation to the intermediary's bank. In some cases, the buyer and seller may not even have knowledge of each other's identities. Depending on the type of transaction, this could be valuable to the parties involved.

> In general, letters of credit (LoCs) are one of the most secure instruments available to international traders, according to the U.S. International Trade Administration. While gathering a foreign buyer's credit information is challenging, the exporter can be satisfied with the buyer's foreign bank's creditworthiness. The importer or buyer is protected as well, as the goods must be shipped before payment is sent.

Back-to-back LoCs essentially substitute the two issuing banks' credit for the buyer's credit and the intermediary's credit. The two letters of credit used in a back-to-back transaction typically have:

*   Different amounts or values
*   Different expiration, shipping, and presentation dates
*   Invoices allowed as substitutes
*   Other terms in common

## Pros and Cons of Using Back-to-Back Letters of Credit

A back-to-back letter of credit provides privacy for both the buyer and seller. They may be used as a substitute if a transferable letter of credit isn't available. They can also help facilitate trade between parties who may be negotiating internationally and cannot verify one another's credit.

However, fees and other charges may apply to a back-to-back letter of credit, and the process involves multiple steps and letters where terms may get murky or vary. As a result, banks tend to discourage using back-to-back letters of credit. If the beneficiary doesn't achieve the terms laid out, there could be a risk to the bank issuing the second letter of credit.

## Example of a Back-to-Back Letter of Credit in Action

Company XYZ is in the U.S. and sells heavy machinery. Company ABC is in China and wants to purchase heavy machinery from XYZ. However, XYZ does not want to take on the risk of defaulted payment by ABC. A London-based trading firm agrees to broker a deal between the two companies. The London firm wants to ensure that the trade is made and that it receives a commission for the deal.

Back-to-back letters of credit can be used to make sure the transaction goes through. So, ABC will request a letter of credit from an established Chinese bank, with the London-based firm as beneficiary. In turn, the London firm will use that letter of credit to go to its own established bank in the U.K. and have it issue a letter of credit to XYZ. Because the creditworthiness of the two banks is already established, it stands in for the creditworthiness of the other companies.

XYZ can now ship its heavy machinery, knowing that once the transaction is complete, it will be paid by the U.K. bank. The broker is also assured of being paid. The credit risk has been removed from the transaction.

## What Is the Risk of a Back-to-Back Letter of Credit?

The primary risk is for the bank issuing the second letter of credit if the original beneficiary doesn't meet the terms and conditions or if there are issues with the settlement date's expiration. As a result, banks don't encourage their use. Generally, a letter of credit is a more secure form of payment for an exporter and less so for the importer.

## Is a Back-to-Back Letter of Credit and Transferable Letter of Credit the Same?

A back-to-back letter of credit is not the same as a transferable letter of credit. With a transferable letter of credit, the beneficiary can transfer the letter of credit's rights and protection to another party. The transferable letter of credit must be either issued as transferable or amended to make it transferable. A back-to-back letter of credit comprises two different letters of credit that are not transferrable.

## Are Back-to-Back Letters of Credit Irrevocable?

Typically, both letters of credit are [irrevocable letters of credit](https://www.investopedia.com/terms/i/iloc.asp). Each letter can't be canceled or modified without all participants' explicit agreement. Amendments can be complicated with a back-to-back letter of credit situation, as the second letter depends on the first.

## The Bottom Line

Back-to-back letters of credit involve two distinct letters of credit, providing a safeguard for international transactions involving intermediaries. This mechanism allows companies to mitigate the risk of dealing with unknown trading partners by utilizing the creditworthiness of established banks. However, this process, while beneficial for securing payments and facilitating trade, entails complexities and additional fees. Banks may discourage their use, especially if terms aren't clearly defined. To navigate these challenges, consider consulting a financial expert to fully understand the potential risks and advantages before proceeding.
