A bank guarantee is often described as a safety net. That is a useful shorthand and a poor definition. A guarantee is a conditional promise by an issuing institution to pay a beneficiary if a defined event occurs, and almost every word in that sentence carries weight in a dispute.
The first question is not what the instrument says but who issued it. An instrument from an institution without the standing to honour it is a document, not a security. Verification of the issuer, and of the instrument's authenticity through the issuing institution's own channels, precedes any discussion of terms.
The second question is what triggers payment. Guarantees fail beneficiaries most often not because the issuer refuses but because the demand did not match the conditions. Precision in drafting the trigger is worth more than a higher face value.
The third is what sits behind it. A guarantee shifts risk; it does not remove it. Where the underlying transaction is weak, an instrument makes the weakness someone else's problem rather than resolving it, and pricing will reflect that.
