Bank Guarantee Borrower Guide: Costs, Claims and Clocks

TL;DR

• A bank guarantee is your bank promising to pay a third party if you default. It is a non-fund limit.
• It helps when a buyer demands security you cannot give in cash. It hurts when it eats exposure and ties up margin.
• On an unconditional guarantee, the bank pays on demand. It does not judge your dispute.
• Price it before signing. On Rs. 25,00,000 at 25 percent margin and 1 percent commission, upfront cash out is Rs. 6,54,500.
• Diary three dates: validity end, claim period end, written release. Expiry alone does not free your margin.

Meera runs a fabrication unit in Indore. A public sector buyer will sign her supply contract only if she furnishes a performance guarantee of Rs. 25,00,000. She has the order, she has the workshop, and she does not have Rs. 25,00,000 in spare cash to park with the buyer. Her bank offers to stand behind her instead, for a price. This guide follows her file, because it shows the three questions every borrower should ask before accepting a guarantee: what does it cost today, what happens if it is called, and when does it truly end.

One reading rule. This page is general information under Indian law as of October 2026, not legal advice. Where a rule comes from the Reserve Bank of India or a statute, this page says so. Where a number comes from bank practice or a worked example, this page says that too. The distinction matters, because only the deed you sign binds your bank and your beneficiary.

What is a bank guarantee in a borrower credit file?

A bank guarantee is a promise by your bank to pay a third party, the beneficiary, if you fail to perform a promise or pay a sum you owe. In your credit file it sits under non-fund based limits, beside letters of credit. No money leaves the bank on the day it is issued. That is why it is called non-fund based: the bank lends its name, not its cash, until the day the guarantee is invoked.

The law gives the three parties fixed names. Under Section 126 of the Indian Contract Act, 1872, a contract of guarantee is a contract to perform the promise, or discharge the liability, of a third person in case of default. The bank is the surety. You, the borrower, are the principal debtor. The beneficiary is the creditor. The Reserve Bank of India repeats this definition in its Non-Fund Based Credit Facilities Directions, 2025, and calls you the obligor.

Two consequences follow from those names. First, under Section 128 of the same Act, the surety liability is co-extensive with the principal debtor liability, unless the contract provides otherwise. The bank promise is measured by your promise. Second, under Section 140, a surety who pays steps into the creditor rights against the principal debtor. When your bank pays your beneficiary, your bank becomes the party you owe. Keep both sentences in mind. They explain every later section of this guide.

The 2025 Directions also set who can get a guarantee at all. A bank issues a non-fund facility only for a customer holding a funded credit facility with it. The exceptions matter for small borrowers: a facility fully secured by eligible financial collateral, a facility backed by another bank counter-guarantee, a facility where the bank holds a no objection certificate from your funded lender, and a facility for an obligor holding no funded facility with any bank in India. If your bank says no, ask which limb it is applying, and which exception you could meet. Our credit appraisal process guide shows where non-fund limits are appraised inside the full sanction journey.

When does a bank guarantee help your file, and when does it hurt it?

A guarantee helps when the counterparty trusts your bank more than it trusts you, and the deal cannot move without that trust. Tender earnest money, a performance guarantee for a supply contract, a guarantee in lieu of a security deposit with a government department, and a guarantee backing an advance payment all fit this shape. The buyer gets bank-grade assurance. You keep your cash working in the business instead of parking it with the buyer for the contract period.

A guarantee hurts in three quiet ways that borrowers discover late. First, it consumes your total exposure. Lenders appraise fund based and non-fund based limits together, so a Rs. 25,00,000 guarantee can shrink the working capital limit available for the same order. Second, it locks margin money and collateral for the full validity plus claim period, which can run well past the contract itself. Third, an invoked guarantee converts into a fund based loan overnight, and a fund based loan that is not serviced on time is assessed under the same classification norms as any other loan. Our IRAC norms guide explains the SMA and NPA bands that then apply.

The test before signing is simple. Ask whether the contract genuinely needs bank assurance, or whether a smaller guarantee, a shorter validity, or a cash deposit for part of the value would satisfy the beneficiary. A guarantee that is larger than the real exposure, or longer than the real contract, is not prudence. It is blocked exposure and blocked margin for no benefit.

Bank guarantee or letter of credit: which one does your deal need?

A bank guarantee pays if the deal fails. A letter of credit pays when the deal succeeds. That one sentence separates them, and it decides which instrument your counterparty should actually ask for. A letter of credit is the bank promise to pay the seller when the seller presents documents proving shipment or performance as specified. A bank guarantee is the bank promise to compensate the beneficiary if you, the applicant, default. Confusing the two is common, and expensive, because each one prices a different risk.

Apply the trigger test to your own deal. If the seller needs to be paid for goods shipped, the instrument is a letter of credit. If the buyer needs compensation when you fail to deliver, the instrument is a bank guarantee. If a counterparty demands a guarantee for a straightforward purchase of goods, push back and ask what default it is actually insuring against. You may be buying the wrong instrument at the wrong price.

Financial guarantee or performance guarantee: what is the bank promising?

A financial guarantee promises money. A performance guarantee promises conduct. The Reserve Bank of India draws this line in its guarantee framework: as a general rule banks provide financial guarantees, and scheduled banks may issue performance guarantees subject to exercising due caution. The distinction is not academic. It decides what the beneficiary must show, and what you can argue about, when a claim arrives.

Read your own deed against this table before signing. A performance guarantee worded as an unconditional promise to pay on demand behaves like a financial guarantee at invocation time, whatever its title says. The title does not protect you. The invocation clause does. If the deed says the bank pays on a simple written demand, treat it as an on demand instrument for every planning purpose in this guide.

What does unconditional and on demand really mean for you?

Unconditional and on demand means the bank pays when the beneficiary demands payment in the form the deed requires, without investigating whether you actually defaulted. The 2025 Directions require this shape: a guarantee issued by a regulated bank shall be irrevocable, unconditional and incontrovertible, with a clear mechanism for honouring it without demur as and when invoked. The same Directions require the bank to honour an invoked guarantee in accordance with the deed terms unless a court order restrains it.

The Supreme Court of India has stated this rule in the same terms for decades. A bank guarantee is an independent contract between the bank and the beneficiary. Once the beneficiary invokes it, the bank is obliged to honour it without demur, irrespective of any dispute between the beneficiary and the party at whose instance the guarantee was given. The classic statement is in Ansal Engineering Projects v. Tehri Hydro Development Corporation (1996), quoted again in a later Supreme Court judgment. Your dispute with the buyer does not pause the bank payment.

Only narrow exceptions let a court restrain payment. The first is egregious fraud that vitiates the underlying transaction, where the bank has notice of it and the beneficiary seeks to benefit from it. The second is irretrievable injury or special equities of an exceptional kind, where money paid cannot realistically be recovered even if you later win. Ordinary commercial disagreement, a disputed quality claim, and financial hardship do not meet either test. Borrowers who plan to fight an invocation in court should understand this before the demand arrives, not after.

Conditional guarantees are the contrast. A conditional deed requires the beneficiary to prove default, often with specified documents or a certificate. That proof burden is real protection, and it is worth negotiating for where the beneficiary will accept it. But do not assume your deed is conditional because the underlying contract is detailed. Only the guarantee deed itself decides what the beneficiary must show.

What do margin money, cash collateral and commission cost?

Margin money is your own contribution held against the guarantee. Cash collateral is money or liquid security the bank holds so that it is not exposed for the full amount. Commission is the bank fee for issuing the guarantee, charged on the full sanctioned amount for the tenor. None of these rates is fixed by the Reserve Bank of India. They are bank policy, set in your sanction terms, and they are negotiable before you sign. Our sanction letter guide shows where non-fund limits, margins and charges appear in the letter itself, and our margin money guide explains the contribution logic behind the percentage.

Meera guarantee is Rs. 25,00,000, a performance guarantee valid from 1 November 2026 to 31 October 2027. Her bank requires 25 percent margin money and charges commission of 1 percent per annum. GST applies at 18 percent on the commission. The workbook computes the same figures from your own inputs. Here is her arithmetic, step by step.

Three negotiation points sit inside that table. First, margin is the largest cash item, and it is the most negotiable: a lower margin, or margin in the form of a lien on an existing deposit instead of fresh cash, changes your working capital on day one. Second, commission runs on the full amount for the full tenor, so a shorter validity or a reducing guarantee that steps down as you deliver saves real money. Third, renewal commission is a second charge, not an extension of the first. Ask for the renewal rate in writing before you accept a multi-year contract backed by a one-year guarantee.

What happens step by step when a guarantee is invoked?

Invocation starts with the beneficiary, not with your bank. The beneficiary lodges a written demand under the deed, within the validity and claim period, for an amount within the guarantee limit. The bank checks the demand against the deed: the right beneficiary, the right form, the right amount, inside the right dates. On an unconditional deed, the bank does not check whether your delivery was actually defective. That check belongs to your contract dispute, not to the invocation.

The bank then pays the beneficiary and converts the exposure. Under the 2025 Directions, once a non-fund facility devolves and converts into a fund based facility, the prudential norms for fund based facilities apply. In plain terms, the guarantee stops being a contingent limit and becomes a loan you owe to your own bank. The bank debits your account or creates a loan account for the paid amount, and it will recover interest and charges as per your counter-indemnity and sanction terms. Your dispute with the beneficiary continues separately, and winning it later does not automatically reverse the bank payment.

Meera file shows the shape. On 15 May 2027, inside validity, her buyer invokes Rs. 18,00,000 of the Rs. 25,00,000 guarantee, claiming short delivery. The bank pays Rs. 18,00,000. Meera now owes her bank Rs. 18,00,000 as a devolved fund based exposure, and Rs. 7,00,000 of the guarantee remains uninvoked until validity and claim period end. Her Rs. 6,25,000 margin stays with the bank under the deed terms until the bank releases it. She can dispute the short delivery claim against the buyer, and she can seek a court restraint only on the narrow fraud or irretrievable injury grounds. She cannot ask the bank to adjudicate the delivery dispute for her.

If the devolved amount is not serviced, it follows the same path as any fund based default, including classification and recovery action. That is why an invoked guarantee deserves the same urgency as a missed loan instalment. Our one-time settlement guide covers the compromise route if the devolved amount becomes unpayable, and our SARFAESI guide covers the separate enforcement track if the devolved loan is secured and turns non-performing. Invocation itself is not a SARFAESI action. The two tracks must not be confused.

What are the validity, expiry and claim period dates to diary?

A guarantee deed carries two different deadlines, and borrowers who track only the first lose money. Validity is the period during which the underlying obligation is covered and a claim can arise. The claim period is the additional window after validity during which the beneficiary must lodge its written claim. A demand lodged after the claim period ends is a demand the bank can refuse under the deed. Diary both dates, and diary the release separately.

One common misunderstanding needs correction. There is no universal legal rule that every guarantee must carry a 12 month claim period. The one year figure that circulates in bank practice comes from Exception 3 to Section 28 of the Indian Contract Act, which permits a bank guarantee deed to provide for extinguishment of rights if no claim is filed in court within a period of not less than one year from the specified event. A law firm reading of a Delhi High Court decision notes that this exception governs the period for enforcing rights in court, not the claim period for lodging a demand with the bank. Read both periods from your own deed. Do not assume a number from practice.

The 2025 Directions support this discipline from the bank side: a bank internal policy on guarantees must address invocation and settlement, claim period, tenor, fee, timelines for release of security, and renewal. If your bank cannot state its release timeline, ask for it in writing before signing. The release timeline is a term of your deal, not an afterthought.

How do you negotiate a guarantee before you sign it?

Negotiate a guarantee the way you would negotiate a loan, because that is what it becomes on invocation. The strongest borrower position is before the deed is signed, when the beneficiary still wants the contract and the bank still wants the account. Seven points cover most of the value, and each one should appear in writing, not in a conversation.

First, cap the amount at the real exposure, and ask for a reducing guarantee that steps down as you deliver milestones. Second, shorten validity to the contract period plus a defined defect window, not an open-ended tail. Third, ask for a conditional invocation clause, with specified documents, wherever the beneficiary will accept one. Fourth, negotiate margin down, or offer a lien on an existing deposit instead of fresh cash. Fifth, fix commission and renewal commission in the sanction letter, with the GST treatment stated. Sixth, fix the release mechanics: the beneficiary return of the original instrument, the bank closure letter, and the margin release date. Seventh, confirm what happens on partial invocation: whether the balance stays live, and whether commission changes.

Two points deserve emphasis because borrowers trade them away casually. A guarantee that auto-renews without your written consent can keep charging commission after the contract ends. Refuse auto-renewal, or cap it. And a guarantee for a group company or a related party is still your exposure: the bank treats the obligor exposure as yours for appraisal and capital purposes, and your file carries it until release. Sign a related party guarantee only with the same diligence you would give your own contract.

What do you file and keep when a guarantee is invoked or expires?

A guarantee file is won or lost on paper, and the paper you need after invocation is paper you should have collected before it. Keep the sanction letter with the non-fund limit, the guarantee deed and any amendments, the counter-indemnity you signed, the margin receipt, every commission debit note, and every letter with the beneficiary about performance and delivery. Our credit appraisal glossary defines the non-fund terms you will meet in these papers in plain language.

When a demand arrives, file four things on the same day. Note the demand date and amount, and check them against the deed limit, validity and claim period. Write to the bank recording that you dispute the invocation, if you do, while stating clearly that you understand the bank must follow the deed. Write separately to the beneficiary disputing the underlying claim with your delivery evidence. And take legal advice immediately if you intend to seek a court restraint, because the fraud and irretrievable injury tests need strong evidence, and delay weakens them.

When a guarantee expires clean, do not file it away and forget it. Obtain the beneficiary release, the bank closure letter confirming nil liability, and the margin refund credit, and check that the limit no longer appears as blocked in your next sanction review. An unclosed guarantee keeps eating exposure and keeps commission running in some bank systems. The file is closed only when the bank says so in writing.
