What Is a Letter of Credit (LC)?

A letter of credit (LC) is a bank guarantee that the correct payment from the buyer will reach the seller on time. If the buyer cannot or does not pay for the purchase. The issuing bank itself covers the outstanding amount.

In short, the bank steps into the buyer's shoes as a guarantor. This is why an LC is also offered as a banking facility to trusted customers. Usually against security or collateral.

Because the bank's credit replaces the buyer's credit. The seller can ship goods to a stranger in another country with confidence. That confidence is the entire reason the LC exists.

Why Letters of Credit Matter in International Trade

International deals carry risks that domestic deals do not. Three factors make the letter of credit indispensable:

• Distance: buyer and seller may sit on opposite sides of the globe.
• Different laws: each country has its own legal and regulatory framework.
• No personal contact: the parties usually do not know each other.

An LC bridges this trust gap. It assures the exporter of payment. Assures the importer that payment will be released only against correct documents. This whole mechanism is overseen by the International Chamber of Commerce (ICC) Uniform Customs. Practice for Documentary Credits (UCP).

Parties to a Letter of Credit

Before learning the types, you must know who is involved. The core parties to a letter of credit are:

1. Applicant (Importer): the buyer who requests the bank to issue the LC.
2. Issuing bank (Opening bank): the bank that issues the LC. Also called the opening banker.
3. Beneficiary (Exporter): the seller in whose favour the LC is opened.

In many international transactions a fourth party - the confirming bank - is added. This is typically the seller's bank. And it adds its own guarantee on top of the issuing bank's promise.

How a Letter of Credit Works

A letter of credit behaves like a negotiable instrument. The issuing bank pays the beneficiary against compliant documents. The LC can even be transferred to another entity through assignment. Giving that party the right to draw.

When used in an international transaction. The LC signals that the seller will receive full and timely payment. Guaranteed by the issuing bank or financial institution. In return. The bank charges a fee and may require collateral from the buyer.

The golden rule: banks deal in documents, not in goods. Payment depends on whether the documents match the LC terms - not on the physical condition of the goods.

Features of a Letter of Credit

The letter of credit carries several distinctive features that examiners love to test:

• LCs are issued against security or collateral. Such as a fixed deposit or a bank deposit.
• The bank charges a fee. Usually a percentage of the LC's size, depending on the LC type.
• Banks must follow the guidelines issued by the International Chamber of Commerce (ICC).
• An LC involves a documentary exchange. Not a transfer of goods or services - so every detail must be accurate.
• Details must correctly state the seller's name. Amount, date, product name and quantity.
• Even a slight mistake in these details can let the bank deny payment.
• Since all parties deal through documents. Payment is independent of any defect found in the goods or services.

Types of Letters of Credit (LC)

Now to the heart of this guide. Banks offer different types of letters of credit that a customer can choose based on need. Here are the most important ones for CAIIB BRBL.

1. Commercial Letter of Credit

A commercial LC is a direct payment method. The issuing bank pays the beneficiary directly when the documents comply. It is the most common LC used for routine trade transactions.

2. Standby Letter of Credit (SBLC)

A standby LC is a secondary payment method. The bank pays the beneficiary only when the buyer or the LC holder fails to pay. Think of it as a backup or safety net rather than the primary route of payment.

3. Revolving Letter of Credit

A revolving LC lets a customer use the same letter for any number of purchases up to a fixed limit within a specified period. It is ideal for buyers and sellers with regular. Repeat dealings, since a fresh LC is not needed for every shipment.

4. Traveller's Letter of Credit

A traveller's LC is used by people going abroad. Under this guarantee. The issuing bank honours the drafts made at certain foreign banks. Giving the traveller access to funds overseas.

5. Confirmed Letter of Credit

In a confirmed LC. A bank other than the issuing bank guarantees the credit. This second bank - usually the seller's bank - is called the confirming bank.

The confirming bank ensures payment under the LC even if the holder or the issuing bank defaults. This type is commonly requested by the issuing bank in international transactions to give the exporter extra comfort.

Common Mistakes Students Make

Avoid these frequent errors that cost easy marks:

• Mixing up commercial and standby LC. One is the primary route; the other is a fallback.
