On-Demand Guarantee: When the Bank Must Pay

A council commissioning works, a buyer of plant or a landlord wants security that turns into money quickly, without first winning an argument. A guarantee that waits for the default to be proved gives it a claim to pursue; one that pays on demand gives it cash, and leaves the customer to pursue the claim instead. That reversal of who waits is the point of the product. The customer carries the risk of an unjustified call; the beneficiary carries the risk of having to repay part of a call later.

For the bank, independence from the underlying contract is what makes the product workable. A bank cannot judge whether a pump station was commissioned on time or a shipment met its specification. It can judge whether a piece of paper matches the terms of its own undertaking, and the on-demand form keeps it in that job.

Where the guarantee incorporates the ICC's Uniform Rules for Demand Guarantees (URDG 758), the rules supply the procedure. The demand must come with a statement saying in what respect the customer is in breach, unless the guarantee excludes that requirement; the guarantor has five business days to examine it; and it must tell its customer of the demand without delay. Many domestic guarantees are written as standalone undertakings without those rules, and then their own wording governs.

Refusal is narrow. The bank can reject a demand that does not comply on its face. Beyond that, English and Australian courts will stop payment where fraud is clearly shown, and Australian courts have also accepted statutory unconscionable conduct as a ground, with a high bar; New Zealand has little reported authority on either ground. A customer can sometimes restrain the beneficiary rather than the bank, where the underlying contract limits when it may call: courts in all three markets have done so, New Zealand's High Court in 2024 until an adjudicator had ruled on the disputed damages. A strong argument that the work was fine is not, by itself, enough.

An engineering firm, constructed for this page, contracts with a regional water authority to build and commission a treatment plant for US$8.0m. The contract requires an on-demand performance guarantee for 10% of the price, and the firm's bank issues US$800,000 against a counter-indemnity and its general security. The firm also has an overdraft with a US$600,000 limit, drawn at US$150,000. The percentage and limits are the example's.

Commissioning runs four months late. The firm blames design changes the authority ordered; the authority blames the firm, and presents a demand for the full US$800,000 with a signed statement that the plant was not completed by the contract date. The demand complies. The firm's lawyers write to the bank that the delay was the authority's doing, which may well be true and is not a ground for refusal. The bank pays within its examination period and debits the firm:

A contingent line has become a debt of US$950,000 on an overdraft built for US$600,000, in a single day, with the firm's position in the dispute unchanged. Fourteen months later an arbitrator finds the authority entitled to US$140,000 of delay damages and orders the other US$660,000 repaid. The firm was largely right. It still had to finance the gap for more than a year, and the bank had to decide in the first week whether to extend the limit, term it out or enforce.

The alternative ties the guarantor's liability to the customer's. A guarantor under a conditional or 'see to it' guarantee can generally raise the defences the customer could, and pays what the beneficiary shows it is owed, so the waiting falls on the beneficiary. Surety providers as well as banks write both kinds. The title on the document does not settle which it is: 'performance bond' is used for both, and a court reads the wording, in particular whether payment turns on a demand or on the customer's liability.

Two relatives behave the same way as the on-demand form. A standby letter of credit does the same job in the form of a credit. A counter-guarantee lets a beneficiary abroad hold a guarantee from a local bank, which is in turn guaranteed by the customer's bank, and both links are usually payable on demand, so a call passes down the chain within days.

A credit officer reads a guarantee line as lending whose timing the customer does not control. The question is not whether the beneficiary will call but what happens to the customer if it does, at the worst moment and for the full amount. That means testing liquidity against the largest calls the customer could face together, reading the expiry dates, since a guarantee without one keeps the exposure alive after the work is done, and checking whether reductions on milestones are written into the guarantee itself, so that the exposure falls as the work progresses rather than when the beneficiary agrees.

In negotiation, the customer's protection lies mostly in the underlying contract: a clause saying when the beneficiary may call, a notice period before it does, a link between the amount called and the loss. Those bind the beneficiary, not the bank, but they give the customer something to take to court before the money moves. The bank's own question is simpler: if this guarantee is paid in full tomorrow, can the customer carry the debt?
