Guide to Irrevocable Letters of Credit (ILOC)

An irrevocable letter of credit (or ILOC) is a written agreement between a buyer (often an importer) and a bank. As part of the agreement, the bank agrees to pay the seller (typically an exporter) as soon as certain conditions of the transaction are met. These letters help reduce a seller’s concern that an unknown buyer won’t pay for the goods they receive. It also helps eliminate a buyer’s concern that an unknown seller won’t send the goods the buyer has paid for.

Irrevocable letters of credit are often found in international trade, though they can be used in other types of financial arrangements to ensure that a seller will be paid, even if the buyer fails to uphold their end of the bargain.

Key Points

•   An irrevocable letter of credit is a written agreement between a bank and a buyer to guarantee payment, ensuring that the seller will be paid even if the buyer fails to fulfill their obligations.

•   Irrevocable letters of credit cannot be canceled or modified in any way without the explicit agreement of all parties involved.

•   Irrevocable letters of credit are commonly used in international transactions but can be used in other situations as well.

•   Alternatives to irrevocable letters of credit include trade credit insurance and standard letters of credit, which offer different levels of flexibility and protection.

What Is an Irrevocable Letter of Credit?

Simply defined, an irrevocable letter of credit represents an agreement between a bank and a buyer involved in a financial transaction. The bank guarantees payment will be made to the seller according to the terms of the agreement. Since the letter is irrevocable, that means it cannot be changed without the consent and agreement of all parties involved.

Irrevocable letters of credit can also be referred to as standby letters of credit. Once an irrevocable letter of credit is issued, all parties are contractually bound by it. This means that even if the buyer in a transaction doesn’t pay, the bank is obligated to make payment to the seller to satisfy the agreement.

Having an irrevocable letter of credit in place is a form of risk management. The seller is guaranteed payment from the bank, which can help to reduce concerns about the buyer failing to pay. And it ensures that the seller will follow through on their obligations by providing whatever is being purchased through the agreement. In simpler terms, a standby letter of credit or irrevocable letter of credit is a sign of good faith on the part of everyone involved in a transaction.

How Does an Irrevocable Letter of Credit Work?

An irrevocable letter of credit establishes a contractual agreement between a buyer, a seller, and their respective banks. It effectively creates a safeguard for both the buyer and the seller, in that:

•   Buyers are not required to forward payment until the seller provides the goods or services that have been purchased.

•   Sellers can collect payment for goods and services, as long as the conditions outlined in the letter of credit are met.

The bank issuing the letter of credit acts as a go-between for both sides, guaranteeing payment to the seller even if the buyer doesn’t pay. Assuming the buyer does fulfill their obligations, they would then make payment back to the bank. In a sense, this allows the buyer to borrow from the bank without formally establishing credit in the form of a loan or credit line. (Check with your financial institution to learn what fees may be involved.)

Before an irrevocable letter of credit is issued, the bank will first verify the buyer’s creditworthiness. Assuming the bank is reassured that the buyer will, in fact, repay what’s owed to complete the purchase, it will then establish the irrevocable letter of credit to facilitate the transaction between the buyer and seller. Irrevocable letters of credit are communicated and sent through the SWIFT banking system.

Irrevocable Letter of Credit Specifications

The exact details included in an irrevocable letter of credit can depend on the situation in which it’s being used. The conditions that are set for the completion of the transaction will also matter. But generally, you can expect an irrevocable letter of credit to include:

•   Buyer’s name and banking information (that is, their bank account number and other details)

•   Seller’s name and banking information

•   Name of the intermediary bank issuing the letter of credit

•   Amount of credit that’s being issued

•   Date that the letter of credit is issued and the date it will expire

An irrevocable letter of credit will also detail the conditions that must be met by both the buyer and seller in order for the contract to be valid. For example, the seller may need to provide written verification that the goods or services referenced in the agreement have been provided before payment can be issued. The letter of credit must be signed by an authorized bank representative. It may need to be printed on bank letterhead to be valid.

Do I Need an Irrevocable Letter of Credit?

You may need an irrevocable letter of credit if you’re doing business with someone in a foreign country. You may also require one if you are conducting a transaction with a new company or individual (one with which you don’t yet have an established relationship).

Irrevocable letters of credit can help to mitigate some of the risk that goes along with international transactions. These letters ensure that if you’re the seller, you get paid for any products or services you’re providing. They also protect you if you’re the buyer, promising that products or services are delivered to you.

An irrevocable letter of credit could also come in handy if you’re still working on building credit for your business and you’re the buyer in a transaction. The bank will pay the money to the seller; you’ll then repay the bank. Payment may be required in a lump sum from your business bank account or another source. Or the bank may also offer the option of repaying it in installments over time. Repaying your obligation could help to raise your business’s creditworthiness in the bank’s eyes. This may make it easier to take out other loans or lines of credit later.

Alternatives to Irrevocable Letters of Credit

An irrevocable letter of credit is not the only way to do business when engaging in international transactions. You may also consider trade credit insurance or another type of letter of credit instead.

Trade Credit Insurance

Trade credit insurance, also referred to as accounts receivable insurance or AR insurance, is used to insure businesses against financial losses resulting from unpaid debts. You can use trade credit insurance to cover all transactions or limit them to ones where you believe there may be a heightened risk of loss, such as transactions involving foreign businesses.

A trade credit insurance policy protects your business in the event that the other party to a financial agreement defaults. It can insulate your accounts receivable against losses if an unpaid account turns into a bad debt. Purchasing trade credit insurance may be an easier way to manage risk for your business overall, as it’s less involved than an irrevocable letter of credit.

Letters of Credit

A letter of credit guarantees payment from the buyer’s bank to the seller’s bank in a financial transaction. Like an irrevocable letter of credit, it establishes certain conditions that must be met in order for the transaction to be completed. But unlike an irrevocable letter of credit, a standard letter of credit can be revoked or modified.

You might opt for this kind of letter of credit if you’re doing business with someone you don’t know and you want reassurance that the transaction will be completed smoothly. A regular letter of credit may also be preferable if you’d like the option to modify or cancel the agreement.

The Takeaway

An irrevocable letter of credit is something you may need to use from time to time if you run a business and regularly deal with international transactions. It adds a layer of protection to buying and selling, as a bank is saying it will cover the transaction. An ILOC, as it’s sometimes known, can provide reassurance when working with a new business or establishing your company overseas. The letter cannot be changed, so you’re getting solid peace of mind.

SoFi members with direct deposit activity can earn 4.00% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate. SoFi members with direct deposit are eligible for other SoFi Plus benefits.

As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.00% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.00% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.

Interest rates are variable and subject to change at any time. These rates are current as of 12/3/24. There is no minimum balance requirement. Additional information can be found at https://www.sofi.com/legal/banking-rate-sheet.
