Standby Letter of Credit: a Worked Example

Written like a credit. Called like a guarantee.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED · 6 MIN READ

// THE SHORT ANSWER

A standby letter of credit is what a counterparty abroad tends to ask for when it wants a bank behind a payment or a contract. It sits unused while the deal goes well. If the bank's customer defaults, the beneficiary presents a short statement saying so, and the bank pays without weighing the underlying argument. It then recovers from its customer, which is why the instrument occupies a credit limit from the day it is issued. Standbys commonly run under ISP98 or UCP 600, and many renew themselves unless the bank gives notice.

BASIS  Practitioner judgment from sixteen years in commercial banking, set out in How Bankers Think (Highbank Press, 2026). Every borrower on this site is a composite constructed for teaching, not a client. The market is mid-market commercial lending as practised in New Zealand and Australia; where a convention differs elsewhere, the page says so.

PART OF Trade Loan

// 01 — WHY THE INSTRUMENT EXISTS

The standby grew up in the United States, where banks were long restricted in issuing guarantees and wrote the same promise as a letter of credit instead. It stayed in use after those limits eased, because beneficiaries across borders liked what came with it: a familiar form and published international rules. In New Zealand, Australia and the UK a domestic counterparty is more likely to take a bank guarantee. A standby appears more often when the beneficiary is overseas, or when its own bank or policy asks for one by name.

It may support a payment, such as a supplier's invoices, a lease or a loan from another lender, or a performance, such as delivery under a contract. The distinction reaches bank capital. The Basel standardised approach applies a 100% credit conversion factor to a standby that serves as a financial guarantee and 50% to one tied to a particular transaction; each regulator sets its own version of that table.

// 02 — HOW ONE IS DRAWN

Three parties matter: the applicant, who is the bank's customer; the issuing bank; and the beneficiary. A bank in the beneficiary's country may advise it or add a confirmation. The text states which rules apply. ISP98 was written for standbys alone. UCP 600 extends to standbys so far as its articles can apply, and suits them less well, having been designed around documentary credits. URDG 758 is written for demand guarantees, though a standby can adopt it.

Whichever is chosen, the bank's obligation stands apart from the commercial contract. It examines what is presented, and a dispute between buyer and seller does not ordinarily stop payment. Four terms carry most of the risk: the amount; the expiry; the drawing condition, which may be nothing more than a signed statement; and any automatic extension, known as an evergreen clause, which renews the standby each year unless the bank gives notice. Some standbys let the beneficiary draw if the bank gives that notice and no replacement arrives.

// 03 — THE EXAMPLE

An importer of solar panels, constructed for this page like every figure in it, buys on 60-day terms from an overseas manufacturer, which will extend up to US$600,000 of credit only with a bank behind it. Its bank issues a standby for US$600,000 subject to ISP98, for twelve months, renewing unless the bank gives 60 days' notice. It is drawn by a signed statement that invoices are unpaid, with copies of those invoices. The fee is 2.0% a year, or US$12,000. The importer also has an overdraft with a limit of US$1.2m, of which US$1.05m is drawn. Rates and amounts are the example's.

In month nine the importer disputes the quality of a shipment and stops paying. The manufacturer presents a statement and invoices totalling US$440,000. The importer asks the bank to refuse, on the ground that the panels are faulty. The bank replies that the presentation complies, pays, and debits the importer's account.

Standby amount 600,000
Drawing on unpaid invoices − 440,000
Still available to the beneficiary 160,000
Before After
Overdraft and drawing 1,050,000 1,490,000
Standby outstanding 600,000 160,000
Total exposure 1,650,000 1,650,000
Overdraft limit 1,200,000
Over the limit after: 1,490,000 − 1,200,000 = 290,000

The total has not moved, which is the point. From the day of issue the bank had counted the full US$600,000 as exposure. What changed is the form of it: contingent exposure became funded, the importer is now US$290,000 over its overdraft limit, and the argument about the panels has become the importer's to pursue against the manufacturer.

The bank now wants out, and gives notice that it will not renew. That does not close the matter. In this standby, non-renewal entitles the manufacturer to draw any remaining balance if no replacement arrives, so the US$160,000 is likely to be called, and the funded balance rises to US$1.65m. A lender cannot end a standby on the terms it might end an overdraft.

// 04 — HOW IT DIFFERS FROM ITS TWO COUSINS

Commercial LC Standby LC Demand guarantee
Expected result paid not called not called
Bank pays on shipping papers statement of demand and statement
default
Usual rules UCP 600 ISP98 or UCP 600 URDG 758

A commercial letter of credit is how a sale gets paid, and the bank expects to pay. A standby is what happens if something else fails. Against an on-demand guarantee the difference is mostly form and rule set: both are independent promises paid on a compliant demand, and a lender reads them in the same way. A guarantee governed by local law may also behave differently from one under international rules, so the wording and the governing law both need reading.

// 05 — WHERE IT DECIDES A FILE

The issuing bank approves a standby as lending to its customer, and asks the same question it would ask of a loan: if this is paid, how does the customer repay? The drafting then matters more than it would on most facilities. A drawing condition that needs only a statement gives the customer little protection, an evergreen clause can keep the exposure alive for years, and a beneficiary's right to draw on non-renewal limits the bank's way out. Each is worth negotiating before issue, because afterwards the beneficiary has to agree to any change.

A lender can also be on the receiving end, as when a standby from a parent's bank supports a loan to a local subsidiary. Then the question is the issuing bank's credit and country, the expiry against the loan's maturity, and whether the lender can draw in time if the standby is not extended. The diary for that date is the lender's own responsibility.

// QUESTIONS PEOPLE ASK

Is a standby letter of credit better than a bank guarantee?
Neither is better in general. Both are independent bank promises paid on a compliant demand. A standby carries international rules and a form widely recognised abroad, which may suit an overseas beneficiary. A locally written guarantee can be simpler for a domestic one and familiar to its lawyers. The choice usually follows what the beneficiary will accept, and the practical differences lie in the drawing conditions, the expiry and the governing law written into the particular document.
Can a bank refuse to pay a standby letter of credit?
It can refuse a presentation that does not comply with the standby, such as a statement in the wrong words, documents missing, or a demand after expiry. It generally cannot refuse a compliant one because its customer says the underlying debt is disputed. Courts recognise a narrow exception for fraud, and each sets its own test for it. A customer who wishes to stop payment usually faces a demanding application to a court, and has little time to make it.
How much does a standby letter of credit cost?
Banks commonly charge a fee on the face amount for each period the standby is outstanding, and add charges for issue, amendment and any drawing. The rate reflects the customer's credit and the security held, so it is set case by case. There is no interest until the standby is drawn, because no money has been advanced. A confirmation by a second bank carries its own fee, priced on the issuing bank and its country.
Can you buy, lease or monetise a standby letter of credit?
Treat such offers with deep suspicion. A genuine standby is issued by a bank at its customer's request, in favour of a particular beneficiary, and is treated by the bank as credit it has extended. The FBI has warned that fraudsters sell fictitious standbys to investors, supported by forged bank messages and advance fees, and that a standby is not an investment and is not traded. An offer to lease one, or to turn one into cash, is a recognised warning sign.
