The Guarantee That Could Cost You the Business: How Much Credit One Signature Ties Up
How an on-demand bank guarantee affects your credit line: a calculation and questions to check
A signature you do not see in your costs
Foreign suppliers sometimes demand an on-demand bank guarantee as a condition for exclusivity. This type of guarantee is often triggered without the supplier having to prove an actual breach, so its terms are an important part of the business assessment.
What it looks like in numbers (an imagined example)
Imagine that you have a credit line of €1,000,000 and the supplier asks for a guarantee of €300,000. Then 30% of the line is under the guarantee and you cannot use it for other purchases.
If the bank fee is 1% a year (an assumption), that is €3,000 a year. The bigger cost is the lost opportunity: €300,000 of purchases that you cannot finance while the guarantee is valid.
If the guarantee is reduced to €200,000 after the first year of orderly cooperation, €100,000 of the line is released. That is why gradual reduction of the amount is not a detail, but a working capital question.
For your own case, take the figures from the bank offer and the contract.
Questions to Check Before Signing
These are not ready-made contract clauses or legal advice, but questions worth thinking about before you accept the terms. The exact wording depends on your contract and the applicable rules.
How is the guarantee triggered (on first demand, on first justified demand, with proof)?
What is the amount and what is it set against (annual quota, stock value, order value)?
How long does it last and what happens when the contract ends?
How much does the bank charge and how much of the credit line or deposit does it tie up?
Can part of the guarantee be replaced by other security?
Before you ask your bank for a guarantee, assess how much of your credit line it really ties up. Describe the amounts and terms to us and we will turn them into a structured report on your options.
