Trade Finance: Letters of Credit & Bank Guarantees 🏦
The Story of the Nervous Toy Buyer
Imagine you want to buy 1,000 teddy bears from a toy factory in another country. You’ve never met them. They’ve never met you.
You worry: “What if I send money and they never ship the toys?”
They worry: “What if we ship the toys and they never pay us?”
Enter the superhero: THE BANK! 🦸
Banks created special “promise notes” that protect BOTH of you. These are called Letters of Credit and Bank Guarantees.
Think of banks as the trusted referee in a game where two strangers need to play fair.
📜 Part 1: Letters of Credit (LC) Overview
What is a Letter of Credit?
A Letter of Credit is like a pinky promise from a bank.
The bank says: “I promise to pay the seller ONLY when they show proof they did their job correctly.”

Simple Example:
- Mom says: “I’ll give you ice cream ONLY when you show me your finished homework.”
- The LC is like Mom’s promise. The homework is like shipping documents.
Why Do People Use LCs?
| Problem Without LC | Solution With LC |
|---|---|
| Seller scared to ship first | Bank guarantees payment |
| Buyer scared to pay first | Payment only after proof of shipment |
| No trust between strangers | Bank is the trusted middleman |
📋 Part 2: Types of Letters of Credit
There are different flavors of LCs, like different flavors of ice cream!
1. Revocable vs Irrevocable LC
| Type | What It Means | Example |
|---|---|---|
| Revocable | Can be cancelled anytime (rare today) | Like a pencil drawing - can be erased |
| Irrevocable | Cannot be cancelled without everyone agreeing | Like a permanent marker - stays put! ✓ |
Most LCs today are IRREVOCABLE because sellers want certainty.
2. Confirmed vs Unconfirmed LC
Unconfirmed LC: Only ONE bank promises to pay (buyer’s bank)
Confirmed LC: TWO banks promise to pay!
- Buyer’s bank + Seller’s local bank both guarantee payment
- Double safety net! 🎪
Example: If you’re selling to someone in a country with banking problems, you want YOUR local bank to ALSO promise payment. That’s confirmation!
3. Sight LC vs Usance (Time) LC
| Type | When Payment Happens | Example |
|---|---|---|
| Sight LC | Immediately when documents arrive | “Pay me NOW when you see my homework!” |
| Usance LC | After a set time (30, 60, 90 days) | “Pay me in 30 days after seeing my homework” |
4. Transferable LC
The seller can transfer the LC to another person (like a supplier).
Example: You buy toys. The seller doesn’t make toys but knows someone who does. They transfer the LC to the actual toy maker.
5. Back-to-Back LC
Two separate LCs linked together.
- First LC: Buyer → Middleman
- Second LC: Middleman → Actual Supplier
Like a relay race where the baton (payment promise) passes from runner to runner! 🏃
6. Standby LC
This is a “backup” LC. Used only if something goes wrong.
Example: A contractor promises to build your house. The Standby LC says: “If the contractor fails, the bank will pay you damages.”
📄 Part 3: LC Documentation Requirements
Documents are the proof that makes the LC work. Without correct documents, NO PAYMENT!
The Big Five Documents
graph TD A["📄 LC Documents"] --> B["📜 Commercial Invoice"] A --> C["🚢 Bill of Lading"] A --> D["📋 Packing List"] A --> E["🔍 Certificate of Origin"] A --> F["📑 Insurance Certificate"]
| Document | What It Proves | Example |
|---|---|---|
| Commercial Invoice | What was sold and the price | “1,000 teddy bears @ $5 each = $5,000” |
| Bill of Lading | Goods were shipped | Ship captain signs: “I have the toys on my ship” |
| Packing List | How goods are packed | “50 boxes, 20 bears each” |
| Certificate of Origin | Where goods were made | “Made in China” certificate |
| Insurance Certificate | Goods are protected during shipping | “If ship sinks, insurance pays” |
The Golden Rule of LC Documents
EVERY WORD MUST MATCH EXACTLY!
If LC says “1,000 Brown Teddy Bears” but invoice says “1,000 Teddy Bears” — REJECTED! ❌
Why? Because banks don’t inspect actual goods. They ONLY check documents. One wrong word = problem.
Example of Rejection:
- LC says: “Port of Loading: Shanghai”
- Bill of Lading says: “Port of Loading: Shanghai Port”
- Result: DISCREPANCY! Bank may refuse payment.
✏️ Part 4: LC Amendment and Discrepancies
What is an LC Amendment?
Sometimes plans change. An amendment is an official change to the LC.
Example Changes:
- Shipping date extended (ship delayed by storm)
- Quantity changed (factory can only make 900 bears)
- Price adjusted (raw materials cost more)
How Amendment Works
graph TD A["🔄 Buyer requests change"] --> B["🏦 Buyer's bank sends amendment] B --> C[🏦 Seller's bank receives it"] C --> D["🏭 Seller agrees or disagrees"] D --> E["✅ If agreed - LC updated"]
IMPORTANT: ALL parties must agree to the amendment. No one can change an irrevocable LC alone!
What are Discrepancies?
A discrepancy is a mismatch between what the LC requires and what the documents show.
Common Discrepancies:
| Discrepancy Type | What Went Wrong |
|---|---|
| Late shipment | Documents show shipping after LC deadline |
| Wrong description | “Blue bears” in LC but “Navy bears” in invoice |
| Missing document | LC required 5 documents, only 4 submitted |
| Spelling errors | “Shanghai” vs “Shanghi” |
| Amount mismatch | LC says $5,000 but invoice says $5,100 |
What Happens with Discrepancies?
- Bank finds the error 🔍
- Seller is notified 📞
- Options:
- Fix documents and resubmit
- Ask buyer to accept despite errors
- Payment gets delayed or refused
Real-World Tip: About 70% of LC documents have discrepancies! That’s why accuracy matters SO much.
🛡️ Part 5: Bank Guarantees Overview
What is a Bank Guarantee?
A Bank Guarantee is the bank saying: “If this person breaks their promise, I will pay you.”
It’s like having a rich uncle who says: “Go ahead and trust my nephew. If he doesn’t pay, I will!”
LC vs Bank Guarantee
| Feature | Letter of Credit | Bank Guarantee |
|---|---|---|
| Purpose | Ensure payment for goods | Ensure someone keeps a promise |
| Payment trigger | Correct documents submitted | The other party fails to perform |
| Common use | Buying/selling goods | Construction, contracts, rent |
Simple Comparison:
- LC = “I’ll pay when you prove you shipped”
- Guarantee = “I’ll pay if they mess up”
📝 Part 6: Types of Bank Guarantees
Just like LCs have types, guarantees have different flavors too!
1. Performance Guarantee
What it does: Promises the job will be done correctly.
Example: A builder promises to finish your house in 6 months. The guarantee says: “If builder doesn’t finish, bank pays you compensation.”
2. Payment Guarantee
What it does: Promises payment will be made.
Example: You hire someone and agree to pay in installments. The guarantee says: “If buyer doesn’t pay, bank pays the remaining amount.”
3. Advance Payment Guarantee
What it does: Protects money paid upfront.
Example: You pay $10,000 upfront for a machine. If the seller never delivers, the guarantee ensures you get your $10,000 back.
4. Bid Bond / Tender Guarantee
What it does: Ensures a bidder is serious about their offer.
Example: Company X bids $1 million for a government project. The bid bond means: “If X wins but backs out, the bank pays a penalty.”
5. Retention Guarantee
What it does: Replaces money held back for quality checking.
Example: Instead of holding 10% of payment until project completion, contractor gets full payment but provides a guarantee.

📢 Part 7: Demand Guarantees
What is a Demand Guarantee?
A Demand Guarantee is a super-strong guarantee.
The beneficiary (person protected) can claim money just by asking — no need to prove the other party did something wrong!
The Magic Words: “Payable on first demand”
How It Works
graph TD A["😟 Beneficiary claims payment"] --> B["📝 Sends written demand to bank"] B --> C["🏦 Bank checks demand is valid"] C --> D["💰 Bank pays immediately"] D --> E["🤔 Bank asks customer for money back"]
Example:
- Landlord has demand guarantee from tenant’s bank
- Tenant damages property but refuses to pay
- Landlord sends demand letter to bank
- Bank pays landlord immediately
- Bank then gets money from tenant
Why So Powerful?
- No investigation needed — Bank pays first, asks questions later
- Very fast — Money comes quickly
- Beneficiary is protected — They get paid even if there’s a dispute
The Risk
Because it’s so powerful, companies are careful about who they give demand guarantees to. The bank WILL pay if asked!
📞 Part 8: Guarantee Claims Process
When Can Someone Make a Claim?
A claim happens when the person protected by the guarantee says: “The other party broke their promise. Pay me!”
Steps in the Claims Process
graph TD A["1️⃣ Problem occurs"] --> B["2️⃣ Beneficiary prepares claim"] B --> C["3️⃣ Claim sent to bank"] C --> D["4️⃣ Bank checks claim validity"] D --> E{5️⃣ Claim valid?} E -->|Yes| F["6️⃣ Bank pays beneficiary"] E -->|No| G["❌ Claim rejected"] F --> H["7️⃣ Bank recovers from customer"]
What Makes a Valid Claim?
- Within validity period — Guarantee hasn’t expired
- Correct format — Matches what guarantee requires
- Right amount — Doesn’t exceed guarantee limit
- Proper declaration — States what went wrong (sometimes)
Example Claim Scenario
Situation: Construction company was supposed to build a school by December. It’s now February and school is not finished.
Claim Steps:
- School board writes to bank
- Letter says: “Company XYZ failed to complete construction by deadline. We claim $50,000 under guarantee number 12345.”
- Bank verifies guarantee is still valid
- Bank verifies claim is properly written
- Bank pays school board $50,000
- Bank asks construction company to repay the $50,000
Expiry Matters!
CRITICAL: Claims must be made BEFORE the guarantee expires!
| Guarantee Expiry | Claim Made | Result |
|---|---|---|
| December 31 | December 28 | ✅ Valid |
| December 31 | January 2 | ❌ Too late! |
