Letter of Credit (LC) Singapore
The bank guarantee that lets Singapore importers and exporters trade with strangers across borders
A Letter of Credit (LC) is a bank-issued guarantee, arranged on behalf of a buyer (importer), promising to pay a seller (exporter) a specified sum once the seller presents documents proving goods have been shipped according to agreed terms. It shifts payment risk in international trade from the buyer’s creditworthiness to the issuing bank’s, making trade between unfamiliar counterparties across borders far less risky.

- An LC is issued by the buyer’s bank and confirms, or guarantees, payment to the seller once shipping documents matching the LC’s terms are presented.
- Singapore’s role as a regional trading and banking hub makes LCs a routine financing tool for import-export businesses, not just large corporations.
- Costs typically include an issuance fee, usually 0.5%-2% of the LC value depending on the bank and buyer’s credit standing, plus document handling charges.
- A Letter of Credit is different from a Standby Letter of Credit, which only pays out if the underlying obligation is NOT met, functioning more like a default guarantee.
- Common LC types include irrevocable (cannot be changed without all parties’ consent), confirmed (a second bank in the seller’s country also guarantees payment), and revolving (covers multiple shipments under one facility).

What Is Letter of Credit (LC)?
International trade between parties who’ve never worked together carries obvious risk: the seller worries the buyer won’t pay after shipping goods, and the buyer worries the seller won’t ship after being paid. A Letter of Credit solves this by inserting a bank’s creditworthiness between the two parties — the seller is paid based on the bank’s promise, not the buyer’s word, as long as the required shipping and compliance documents are presented correctly.
For Singapore-based import-export businesses and the banks that serve them, such as DBS, OCBC, and UOB, trade finance products built around LCs remain one of the most common ways to de-risk cross-border deals, particularly with counterparties in markets where credit information is harder to verify.
How It Works in Singapore
The typical flow: (1) buyer and seller agree on LC payment terms in their sales contract; (2) the buyer applies to their bank, the issuing bank, to open an LC in the seller’s favour; (3) the issuing bank sends the LC to the seller’s bank, the advising or confirming bank; (4) the seller ships the goods and presents the required documents, such as a bill of lading, commercial invoice, and packing list, to their bank; (5) the banks verify the documents strictly match the LC’s terms; and (6) once verified, the issuing bank pays, regardless of whether the buyer has separately settled with their bank yet, since that’s a separate credit arrangement between the buyer and their bank.
Worked Example
A Singapore-based electronics importer agrees to buy US$200,000 of components from a manufacturer in Vietnam. The manufacturer, unfamiliar with the importer’s payment history, insists on an LC. The importer’s bank issues an irrevocable LC for US$200,000, charging a 1% issuance fee (US$2,000). The manufacturer ships the goods and presents the bill of lading and invoice to its bank, which forwards them to the Singapore issuing bank for verification. Once the documents are confirmed to match the LC’s terms exactly, the issuing bank pays the US$200,000, and the importer separately settles that amount with their bank under the credit terms they’d arranged.
Worked Example
Advantages
- Shifts payment risk from the buyer’s individual creditworthiness to a bank’s guarantee, which is particularly valuable for first-time trading relationships.
- Gives the seller strong assurance of payment as long as they ship correctly and present compliant documents.
- Gives the buyer assurance that payment is only released once proof of shipment, matching agreed terms, is presented.
- Widely understood and standardised internationally under rules like the ICC’s Uniform Customs and Practice for Documentary Credits (UCP 600), reducing cross-border legal ambiguity.
Risks and Limitations
- Document discrepancies, even minor ones, such as a misspelled company name, can cause banks to reject a presentation and delay payment.
- Issuance and document handling fees add a real cost to a trade deal, particularly for smaller transaction sizes.
- Buyers typically need to provide collateral or have sufficient credit lines with their bank to get an LC issued, which can tie up working capital.
- An LC only guarantees payment for what’s documented — it doesn’t guarantee the actual quality or condition of the goods shipped.
- Processing and verifying documents between multiple banks across time zones can introduce delays compared to simpler payment methods.
Letter of Credit vs Standby Letter of Credit
| Feature | Letter of Credit | Standby Letter of Credit |
|---|---|---|
| Primary purpose | Guarantees payment for a specific trade transaction | Guarantees payment only if the underlying obligation is NOT met |
| When it pays out | Upon presentation of compliant shipping documents | Only on default or non-performance |
| Typical use case | Import-export trade financing | Performance guarantees, rental deposits, contract backstops |
| Expected to be drawn on? | Yes, as the normal payment mechanism | No, ideally never drawn |
The Bottom Line
A Letter of Credit remains one of the most trusted tools in cross-border trade precisely because it replaces trust between strangers with the credibility of a bank — for Singapore’s import-export businesses, the fee is usually a small, worthwhile price for removing the single biggest risk in dealing with an unfamiliar overseas counterparty.
