What it means
The core problem trade finance solves is trust across distance. An exporter does not want to ship $500,000 of goods to a buyer it has never met, and the buyer does not want to wire $500,000 for goods it has not seen, so a bank steps between them and takes on part of the risk.
A letter of credit is the classic answer. The buyer's bank promises to pay the seller once specified documents, usually a bill of lading and an inspection certificate, are presented, which means the seller is relying on a bank's credit rather than the buyer's.
Beyond payment security, trade finance also solves timing. Export invoices are often written on 90-day or 120-day terms, and few exporters can afford to wait that long, so banks advance most of the invoice value immediately and collect from the buyer later.
The pricing has two parts that people frequently confuse. There are fees, charged as a percentage of the facility for issuing or confirming an instrument, and there is a discount or interest charge on money actually advanced, and only adding both together gives the true cost.
Trade finance is deliberately self-liquidating, meaning each advance is repaid by the specific sale it funded rather than by the general cash flow of the business. That structure makes lenders more comfortable with growing or thinly capitalised exporters than a conventional term loan would.
In practice
Real-world examples
Example 1
A machinery exporter wins a first order from a buyer in Vietnam and insists on an irrevocable letter of credit confirmed by a bank in London. The confirmation costs 0.8% of the order value but removes both the buyer risk and the country risk from the exporter's books.
Example 2
A textiles importer uses a documentary collection rather than a letter of credit because it has traded with the same mill for eleven years. The cheaper instrument saves around $6,000 a year in bank charges while still keeping the shipping documents out of the buyer's hands until payment is arranged.
Example 3
A supermarket group runs a supply chain finance programme that lets its smaller suppliers get paid on day 5 at the supermarket's own borrowing rate. Suppliers gain cheap cash, and the supermarket extends its own payment terms to 90 days without pushing anyone into distress.
Think of it
Trade finance is like an escrow service used when buying a house. The buyer puts money with a trusted third party, and the seller knows the cash is real before handing over the keys, ensuring neither side gets cheated.
Formula
Calculation
Total Cost of Trade Finance = Facility Fees + Discount Charge, and the effective annual rate is:
Effective Rate = (Total Cost / Net Advance) x (360 / Days)
An exporter ships $500,000 of goods on 90-day terms and discounts the invoice with its bank. The bank charges a facility fee of 0.375% for the quarter and a discount rate of 6% a year on the face value.
Step 1: Discount charge = $500,000 x 6% x 90/360 = $7,500
Step 2: Facility fee = $500,000 x 0.375% = $1,875
Step 3: Total cost = $7,500 + $1,875 = $9,375
Step 4: Net advance received today = $500,000 - $9,375 = $490,625
Step 5: Effective rate = ($9,375 / $490,625) x (360/90) = 0.0764, or 7.6% a year
The exporter receives $490,625 immediately instead of $500,000 in three months, at an effective annual cost of 7.6%. That is the number to compare against the overdraft rate, not the headline 6% discount rate, because the fee lifts the true cost by roughly 1.6 percentage points.Case study
Seen in the real world
This case study is illustrative and the company is fictional. Kestrel Marine Supplies, an invented chandlery exporter, landed a $500,000 order from a new customer three time zones away and almost turned it down because the terms demanded 90 days credit.
Its bank structured a facility combining a confirmed letter of credit with invoice discounting. The total cost came to $9,375 against a net advance of $490,625, an effective 7.6% a year, which sat comfortably below the 24% gross margin the order carried.
What surprised the fictional management team was the administrative burden rather than the price. Two shipments were delayed for eleven days because the packing list description did not match the letter of credit wording exactly, and after that the company built a document checklist that had to be signed off before any container left the yard.
Watch out
Common mistakes
- Comparing only the discount rate between providers. Arrangement, confirmation and document handling fees can add several percentage points to the effective cost.
- Assuming a letter of credit guarantees payment regardless of paperwork. Banks pay against compliant documents, and a single mismatched description can allow a refusal.
- Using trade finance to plug a general cash shortfall. These facilities are tied to specific shipments, and drawing on them without matching sales leaves the business exposed when the advance falls due.
Questions
People also ask
Is trade finance only for international deals?
No, domestic invoice discounting and supply chain finance use the same mechanics, though letters of credit are far more common across borders.
Does trade finance appear as debt in the accounts?
Advances against invoices usually do sit within short-term borrowings, while an unused letter of credit facility is generally disclosed as a contingent liability instead.
Who pays for a letter of credit?
The buyer normally pays the issuing costs and the seller pays any confirmation costs, but this is negotiable and should be settled in the sales contract.
