How to Underwrite a Trade Finance Deal

Underwrite trade finance transaction by transaction. Map the full cycle from purchase to sale, identify who bears risk at each step, and secure the lender's position through letters of credit, title to goods, insurance and assigned receivables. Tenor, counterparty and country risk, and control of documents and collateral matter more than the borrower's leverage.

What makes trade finance underwriting different

Trade finance funds the movement of goods: an importer paying a foreign supplier, a commodity trader carrying cargo between purchase and sale, or an exporter waiting to be paid by an overseas buyer. Loans are short, often 30 to 180 days, and self-liquidate when the goods are sold. Value comes from fees and spread on high-turnover, collateralized exposures. Risk comes from the chain itself: a supplier who ships nothing, a buyer who rejects cargo, a bank in a weak jurisdiction failing to honor a letter of credit, goods that are pledged twice, or a sanctions breach. Documentary control is the heart of the credit.

Banks and trade finance funds underwrite the transaction structure first and the borrower second, asking whether the goods, documents and payment flows are controlled well enough that the deal repays even if the borrower weakens. Investors in trade finance funds or note programs look at portfolio diversification by commodity, country and obligor, historical loss and fraud experience, insurance coverage and the manager's operational controls. Equity investors in a trading company, by contrast, focus on gross margins per cargo, hedging discipline and how much bank capacity the business can access, because trade lines are its working capital.

Key metrics

Transaction tenor

Shorter cycles mean faster self-liquidation and less exposure to price moves and counterparty deterioration.

Most trade finance exposures are typically under one year, with many under 180 days.

Loan-to-value on goods

Commodity prices move, so the lender needs a margin between the advance and the hedged or market value of the cargo.

Lenders commonly advance around 70% to 90% of hedged commodity value, lower for unhedged or illiquid goods.

Counterparty and issuing bank credit

Repayment depends on the buyer or the bank issuing the letter of credit, not just the borrower.

Country and transfer risk

Currency controls, sanctions or political events can block payment even when the buyer is willing to pay.

Insurance coverage

Cargo, political risk and credit insurance can shift loss away from the lender, but only if the policy terms match the exposure.

Historical performance and dilution

Rejected shipments, quality claims and price adjustments erode receivables in the same way dilution does in factoring.

How to underwrite it, step by step

Map the physical and payment flow of the transaction from supplier through borrower to end buyer.
Run KYC, sanctions and adverse media checks on every party, vessel and jurisdiction involved.
Assess the credit of the buyer, the issuing or confirming bank and the borrower.
Define the security package: letters of credit, assignment of receivables, title documents, warehouse receipts and insurance.
Set the advance rate against hedged value and agree margin call mechanics for price moves.
Appoint collateral managers or inspection agents to verify quantity and quality of goods.
Release funds only against compliant documents and monitor each shipment until repayment.

Key risks and mitigants

Documentary fraud and duplicate financing of the same cargo

Verify bills of lading with carriers, use electronic title registries where possible, and appoint independent collateral managers.

Commodity price decline during the cycle

Require hedging, set advance rates with margin cushion, and include margin call rights.

Buyer rejection or quality disputes

Use independent inspection at loading and contracts with clear quality terms and arbitration.

Sanctions or country transfer restrictions

Screen every party and route, use confirmed letters of credit from strong banks, and buy political risk insurance.

Issuing bank failure or refusal to pay

Have the letter of credit confirmed by a highly rated bank and present strictly compliant documents.

Typical financing and deal structure

Trade finance takes several forms: documentary letters of credit and standby letters of credit, pre-export finance repaid from export receivables, borrowing base facilities secured on inventory and receivables of commodity traders, and receivables purchase or supply chain finance programs. Facilities are usually short-term, uncommitted or revolving, and priced over a floating benchmark. Lenders take security over the goods and the receivables, an assignment of insurance proceeds, and control accounts for collections. Larger deals are syndicated or participated, and risk is often distributed through credit insurance or risk participation agreements. Export credit agencies support some flows, and SBA export programs cover certain US exporters.

Red flags

Bills of lading that cannot be verified with the carrier
Counterparties or vessels with sanctions exposure or opaque ownership
Margins on the trade that look too good for a commodity flow
Borrower resists collateral manager access or independent inspection
Round-tripping between related parties with no clear end buyer

Frequently asked questions

How does a letter of credit reduce risk?

A letter of credit replaces the buyer's payment promise with a bank's. The bank commits to pay the seller when compliant documents, such as a bill of lading and invoice, are presented. Underwriters then focus on the issuing bank's credit and the documents rather than the buyer. Confirmation by a second bank adds further protection against issuing bank or country risk.

What is a borrowing base facility for commodity traders?

It is a revolving line where availability is calculated from the value of eligible collateral: hedged inventory, receivables and goods in transit, each with its own advance rate. Traders report the borrowing base frequently, and the lender monitors through collateral managers and audits. It lets traders finance many cargoes at once while the lender keeps control of collateral.

Why is fraud a major risk in trade finance?

Trade relies on documents representing goods that the lender never sees. Fake or duplicated warehouse receipts and bills of lading can allow the same cargo to be pledged to several banks, or cargo that does not exist to be financed. Losses from these schemes can be total, so lenders invest heavily in verification, inspection and digital title systems.

Is trade finance considered low risk?

Trade finance is often seen as lower risk than general corporate lending because exposures are short, self-liquidating and backed by goods or bank undertakings. That view holds only when structure and controls are sound. When documents are not verified or collateral is not controlled, losses can be large, as several commodity finance fraud cases have shown.
