Trade Guarantees Explained: Tender, Performance and Advance Payment Bonds

What a bank guarantee is, how tender bonds, performance guarantees and advance payment guarantees differ, and what a business should check before one is issued.

A bank guarantee is a promise by a bank to pay a beneficiary a stated sum if the bank's customer fails to meet an obligation. It is one of the most widely used instruments in trade and project work, and one of the most frequently misunderstood — largely because it protects the beneficiary rather than the customer who requested it.

What a guarantee actually does

In a payment transaction, the question is whether money will change hands. In a guarantee, the question is whether an obligation will be performed. A contractor may fail to complete a project; a supplier may fail to deliver against a contract; a bidder may withdraw after being awarded work. A guarantee answers the beneficiary's question: if that happens, who pays?

The bank answers it. In return, the bank takes a counter-indemnity from its customer, which means the customer remains ultimately liable to the bank.

The three guarantees most businesses meet

Tender (bid) bonds

A tender bond accompanies a bid. It assures the buyer that the bidder is serious and will not withdraw a bid after submission or refuse to enter a contract if awarded the work. Tender bonds are typically a modest percentage of the contract value and are released once the contract is signed and a performance guarantee is in place.

Performance guarantees

A performance guarantee supports the delivery phase of a contract. It assures the buyer that the supplier or contractor will meet the agreed obligations, and gives the buyer a route to compensation if they are not met. Performance guarantees usually run for the duration of the contract plus a maintenance or defects period.

Advance payment guarantees

Where a buyer pays part of a contract value in advance, an advance payment guarantee protects that money. If the supplier fails to deliver, the buyer can call on the guarantee to recover the advance. These are common in manufacturing, construction and large equipment purchases.

Where guarantees fit alongside letters of credit

Letters of credit and guarantees are often mentioned together, but they do opposite jobs. A letter of credit secures payment to a seller who has shipped. A guarantee secures performance for a buyer who has paid or committed. In a large project it is normal to see both: a letter of credit for the supply of materials and a performance guarantee for the installation work.

What to check before a guarantee is issued

  • The wording and the governing rules. Guarantees may be issued under the ICC's Uniform Rules for Demand Guarantees (URDG 758) or drafted bespoke. The wording determines when the beneficiary can call, and on what evidence.
  • Whether it is conditional or on demand. A conditional guarantee requires the beneficiary to demonstrate a breach. An on-demand guarantee is payable against a written demand, which places more risk on the applicant.
  • The expiry date and the release mechanism. Open-ended guarantees create long-running contingent liabilities. Agree a realistic expiry and a process for returning the original document.
  • The counter-security required. The bank will set out what it needs from the applicant — cash margin, security, or a clean facility depending on the customer's standing.
  • The currency and the amount. A guarantee denominated in a foreign currency is also a currency exposure for as long as it runs.

Key takeaways

  • A guarantee protects the beneficiary against non-performance; the applicant remains liable to the bank.
  • Tender bonds support a bid, performance guarantees support delivery, advance payment guarantees protect money paid up front.
  • On-demand guarantees carry more risk for the applicant than conditional guarantees.
  • Agree the wording, expiry and release process before issuance, not after.

Frequently asked questions

What are trade guarantees?

Trade guarantees are bank undertakings to pay a beneficiary if the bank's customer fails to perform a contractual obligation. They are used to support bids, contract performance and advance payments in trade and project work.

What is the difference between a letter of credit and a bank guarantee?

A letter of credit secures payment to a seller against compliant shipping documents. A bank guarantee secures performance, compensating a buyer or beneficiary if the other party fails to meet its obligations.

How long does a bank guarantee take to issue?

Timing depends on the bank's assessment of the applicant and the transaction, and on whether the wording has been agreed in advance. Complex or bespoke wordings take longer than standard templates, so start the process well before the bid or contract deadline.
