Bank Guarantee

A Bank Guarantee is a written undertaking issued by a bank on behalf of its customer, committing the bank to pay a stated sum to a named beneficiary unconditionally and on demand, without requiring the beneficiary to prove loss or obtain a court judgment first.

What is a Bank Guarantee?

In international procurement, bank guarantees appear at multiple stages of the contracting cycle. A bid security (tender guarantee) covers the pre-award phase; a performance-guarantee secures execution of the awarded contract; an advance-payment-guarantee protects advance funds released to the contractor; and a retention-money-guarantee replaces withheld retention at completion. Each of these instruments is a bank guarantee, differentiated only by its purpose, amount, and validity period.

Development banks and UN agencies specify acceptable forms and require that guarantees be issued by reputable banks, often requiring a first-class international bank or a locally incorporated bank confirmed by an international correspondent. A guarantee that deviates from the prescribed wording or is issued by a bank deemed unacceptable is treated as non-compliant, which can disqualify the bid or prevent contract signature.

Why Bank Guarantee matters for bidders

The practical constraint for suppliers is bank credit lines. Every outstanding guarantee ties up a portion of the company's credit facility with its bank, limiting capacity for new guarantees on other contracts. Suppliers pursuing multiple simultaneous international tenders must plan their guarantee capacity alongside their financial ratios. Additionally, the bank charges a commission, typically 0.5 to 1.5 percent per annum of the face amount, which is a real cost to be included in bid pricing. Firms bidding with a surety-bond as an alternative should confirm the contracting authority accepts that form, since some buyers only accept bank guarantees.

FAQ

What does "unconditional and on demand" mean?

It means the buyer can call the guarantee and receive payment from the bank simply by presenting a written demand, without needing to prove that the contractor breached the contract.

Can a guarantee be issued in any currency?

Guarantees are issued in the currency specified by the contracting authority, commonly USD, EUR, or the project country's local currency. Suppliers should confirm their bank can issue in that currency without a significant conversion cost.

How quickly can a bank issue a guarantee?

Processing times vary by bank and jurisdiction but typically range from two to five business days for standard forms. Suppliers should apply well before the bid submission deadline to avoid last-minute delays.
