A standby letter of credit (SBLC) is a bank-backed guarantee of payment. If the buyer defaults, the exporter claims payment directly from the issuing bank instead of chasing the buyer.
It is called "standby" because it sits in reserve and is ideally never drawn: it exists to reassure the seller, while the buyer still pays through the normal route.
In practice, an SBLC is a safety net for the deal, not the pipe through which your export proceeds usually flow.
For an Indian exporter negotiating with a new overseas buyer, that reassurance can be the difference between winning the order and losing it.
This guide explains how an SBLC differs from a commercial letter of credit and a bank guarantee, the types and parties involved, the RBI and FEDAI framework that governs it in India, what it costs, and several worked scenarios showing how it plays out.
If you also need to actually collect the money once the deal closes, that is a separate step from the guarantee, and one where international business payments infrastructure comes in.
What is a standby letter of credit and what is the SBLC full form?
The SBLC full form is standby letter of credit. It is a written undertaking by a bank to pay the beneficiary if the applicant fails to meet an obligation.
Because it is a secondary promise, the bank pays only on default, and only against the documents the SBLC specifies, such as a written demand and a statement that the buyer has not paid.
This is what separates a standby letter of credit from a commercial LC.
A commercial letter of credit is a primary payment mechanism: the bank pays when the seller presents compliant shipping documents, so it is expected to be used every time. An SBLC is the opposite in spirit.
Everyone hopes it is never triggered, because a triggered SBLC means something went wrong.
Most SBLCs are governed by ISP98 (the International Standby Practices) or, in some cases, UCP 600, and the beneficiary draws on it only as a last resort.
When you are also weighing informal credit against a bank-backed promise, it helps to understand plain trade credit first.
Standby letter of credit vs letter of credit vs bank guarantee
Exporters often confuse these three instruments. They overlap, but they are used at different points and pay out under different conditions.
The standby letter of credit vs letter of credit distinction is about when the bank expects to pay; the standby letter of credit vs bank guarantee distinction is mostly about which rulebook governs the promise.
| Feature | Commercial LC | Standby LC (SBLC) | Bank guarantee |
|---|---|---|---|
| Primary use | Main payment method for a shipment | Backup guarantee against default | Backup guarantee against non-performance or non-payment |
| When the bank pays | On presentation of compliant documents | Only if the buyer defaults | Only if the beneficiary invokes it |
| Governing rules | UCP 600 | ISP98 (or UCP 600) | Local law / FEMA (Guarantee) Directions in India |
| Exporter's view | Expect it to be used | Hope it is never drawn | Hope it is never invoked |
The practical takeaway: reach for a commercial LC when you want the bank to be your paying party on every shipment, and an SBLC or bank guarantee when you want protection in case the buyer lets you down.
An SBLC and a bank guarantee are close cousins; the SBLC is the form more familiar to counterparties in the United States and much of the world.
SBLC vs bank guarantee for a services contract
A Hyderabad IT services firm signed a two-year managed-services deal with a European enterprise.
The client's procurement team was comfortable with a bank guarantee under local law, while the Indian firm's AD bank preferred issuing an SBLC under ISP98, a rulebook its correspondent network knew well.
Both instruments would have paid out on the same trigger (the client failing to pay a valid invoice), so the choice came down to familiarity and documentation.
They settled on an SBLC because the internationally recognised ISP98 format avoided a drafting argument over which country's guarantee law applied. For a cross-border services contract, that neutrality is often the deciding factor.
What are the types of standby letter of credit?
Standby letters of credit are classified by the obligation they secure. The common types of standby letter of credit are:
- Financial SBLC: Guarantees a payment obligation, such as the buyer paying for goods or services. This is the type most exporters encounter.
- Performance SBLC: Guarantees that a party will complete a contracted task or project to agreed standards.
- Advance-payment SBLC: Protects a buyer who has paid an advance, ensuring the money is returned if the seller fails to deliver.
- Counter SBLC: A back-to-back arrangement where one bank's standby supports the issuance of another, often across borders.
Choosing the right type matters, because the SBLC pays only against the specific default it names. A financial SBLC will not help a buyer who is worried about non-delivery, and vice versa.
If you sell services rather than goods, a performance SBLC is often what a large client asks you to provide, while you in turn ask them for a financial SBLC to cover their payment.
Who are the parties to an SBLC?
An SBLC involves the same core roles as any documentary credit:
- Applicant: The buyer (importer) who requests the SBLC from their bank and bears the fees.
- Issuing bank: The applicant's bank, which gives the undertaking to pay.
- Beneficiary: The exporter, who can draw on the SBLC if the buyer defaults.
- Advising or confirming bank: A bank in the exporter's country that advises the SBLC, and, if it confirms, adds its own promise to pay.
A confirming bank is valuable when the exporter is unsure of the issuing bank or the buyer's country risk, because it moves the payment promise closer to home.
Knowing who bears which fee also matters when you negotiate: the applicant usually pays issuance, but advising and confirmation fees often land on the beneficiary unless you agree otherwise.

How does an SBLC work in an export deal? A step-by-step example
The mechanics are straightforward once the roles are clear. Here is a standby letter of credit example as a typical export flow:
- Agree the terms. The exporter and buyer sign a contract and agree that the buyer will arrange an SBLC in the exporter's favour.
- Buyer applies. The buyer approaches their bank, which assesses their credit and issues the SBLC, usually under ISP98.
- SBLC is advised. The issuing bank sends the SBLC to a bank in the exporter's country, which advises (and may confirm) it.
- Trade proceeds. The exporter ships the goods or delivers the services and invoices the buyer as normal.
- Normal payment, ideally. The buyer pays through the ordinary route, and the SBLC lapses unused at expiry.
- Default, if it happens. If the buyer does not pay, the exporter presents the demand and documents the SBLC requires, and the issuing bank pays.
Because the guarantee sits behind the ordinary payment, agreeing solid export payment terms upfront remains essential; the SBLC is the backstop, not the plan.
It also helps to know how to vet the counterparty in the first place, which is where advice on how to find international buyers for export pays off before any SBLC is drafted.
What happens when an SBLC is drawn? The claim steps
Most SBLCs expire unused, but you should know the drawing procedure before you need it. Say a buyer defaults on a payment the SBLC covers.
The exporter (beneficiary) does not get paid automatically; a standby letter of credit is a claim instrument, so you have to present a compliant demand.
The claim steps generally run:
- Confirm the default. The payment due date passes and the buyer has not paid through the normal route.
- Check the SBLC terms. Read exactly what documents the SBLC requires, most often a written demand plus a signed statement that the buyer has not paid, and note the expiry date.
- Prepare a compliant presentation. Draft the demand precisely as the SBLC wording specifies; even small deviations can lead the bank to reject the presentation.
- Submit within validity. Present the documents to the issuing or confirming bank before the SBLC expires, through your advising bank.
- Bank examines and pays. The bank checks the documents against the SBLC terms only (not the underlying dispute) and pays if they comply.
An SBLC actually drawn
A Surat textile exporter held a financial SBLC for USD 40,000 against a Gulf buyer. The buyer disputed the final shipment and stopped paying.
Because the SBLC required only a written demand and a statement of non-payment (not proof of who was right in the dispute), the exporter's AD bank forwarded a compliant demand to the issuing bank, which paid the USD 40,000 within the examination window.
The commercial dispute continued separately, but the exporter had the cash. That independence from the underlying argument is the whole point of a standby letter of credit.
What does a standby letter of credit cost? How much does an SBLC cost?
An SBLC carries fees because the bank is putting its own balance sheet behind the promise.
On the question of how much does an SBLC cost, the standby letter of credit cost is usually quoted as an annual percentage of the SBLC value, plus flat charges, and it varies with the applicant's credit and the tenor.
| Charge | Typically borne by | Basis |
|---|---|---|
| Issuance / commission | Applicant (buyer) | Percentage per annum on the SBLC amount |
| Advising fee | Often the beneficiary | Flat fee by the advising bank |
| Confirmation fee | Beneficiary (if confirmed) | Percentage reflecting country and bank risk |
| Amendment / SWIFT charges | Party requesting the change | Flat, per event |
Because a confirmed SBLC adds a second bank's risk view, the confirmation fee can be significant for higher-risk corridors. Always confirm the exact figures with your AD bank, as they are credit-dependent and not fixed.
The cost of confirming on a higher-risk corridor
A Pune engineering exporter took a USD 300,000 order from a buyer in a region its bank rated as elevated risk. An unconfirmed SBLC left the exporter relying on a foreign issuing bank it did not know.
So it asked its Indian AD bank to add confirmation, moving the payment promise onto a bank it trusted at home.
The confirmation fee reflected the country and bank risk and was noticeably higher than a plain advising fee would have been.
The exporter treated that fee as the price of sleeping at night: it converted an unfamiliar foreign promise into a domestic one. On a low-risk corridor, it would likely have skipped confirmation to save the cost.

RBI guidelines for a standby letter of credit in India
The RBI guidelines for a standby letter of credit sit within the wider framework for guarantees. In India, only Authorised Dealer (AD) banks may issue guarantees and standby letters of credit, and they do so under RBI's rules.
RBI treats a bank guarantee or SBLC as a non-funded (contingent) exposure, evaluated with the same rigour as a loan, because the bank may have to pay out.
RBI's directions on non-fund based credit facilities, which cover guarantees and letters of credit and take effect from April 2026, consolidate this framework.
Under the Foreign Exchange Management (Guarantee) Directions, AD banks may issue such instruments in the ordinary course of export business, essentially to guarantee export performance rather than to fund the buyer.
Two India-specific references are worth knowing. FEDAI (the Foreign Exchange Dealers' Association of India) issues guidance that AD banks follow when issuing SBLCs, including which rulebook applies (ISP98 or UCP).
And India Exim Bank runs guarantee and SBLC-linked programmes that support Indian exporters and project exports, which can be useful for larger or government-backed deals.
A letter of undertaking is a related instrument you may meet in trade finance, though it serves a different purpose from an SBLC.
For the compliance paperwork on the money you do receive, keep your realisation and repatriation of export proceeds obligations in view, since RBI expects proceeds to be brought into India within set timelines.
SBLC for exporters: winning a new buyer
The clearest case for an SBLC for exporters is the first order with an unknown buyer, where trust has not yet been built.
Securing a USD 200,000 order
A Bengaluru software exporter signs a USD 200,000 annual contract with a first-time buyer in the United States. The buyer's creditworthiness is unproven, so the exporter asks for a financial SBLC for USD 50,000, covering roughly a quarter's billing.
The buyer's US bank issues the SBLC under ISP98, and an Indian AD bank advises it. Each quarter the exporter delivers and invoices, and the buyer pays on time, so the SBLC is never drawn.
It simply renews and then lapses at the end of the term.
The exporter has spent nothing on drawing it, gained a buyer willing to commit, and the only real cost was the buyer's issuance commission plus a modest advising fee.
Had the buyer missed a payment, the exporter could have presented a written demand to the issuing bank and been paid up to USD 50,000.
Notice what the SBLC did and did not do. It let the exporter say yes to a large, unfamiliar order without carrying the full default risk.
It did not, on its own, move a single dollar of the routine quarterly payments into India. Those still flowed through the ordinary receiving route, which is a separate piece of the puzzle.
Where the SBLC ends and payment begins
Here is the honest limitation. An SBLC is a fallback guarantee, not a payment method.
It reassures you that you will be paid if the buyer defaults, but on a healthy deal it is never triggered, so it does nothing to move your actual proceeds into your Indian account.
For the routine receipt of export payments, you still need a receiving or settlement setup that credits your account and generates the compliance trail.
That is where Xflow fits, honestly and separately from the guarantee.
Xflow is a cross-border receiving platform with final RBI PA-CB authorisation, as of February 2026, so Indian exporters can collect payments from 140+ countries, receive at a mid-market rate with up to 50% savings versus typical bank routes, and get automatic eFIRA for each receipt to support FEMA and EDPMS compliance.
It does not replace an SBLC, and it is not tax or legal advice; it handles the money that actually arrives.
Your CA and AD bank remain the right people to structure the guarantee itself, and a firc request letter is one less thing to chase when the certificate is generated for you.

Frequently asked questions
A commercial LC is the main payment method: the bank pays when the exporter presents compliant shipping documents. An SBLC is a backup guarantee: the bank pays only if the buyer defaults. An LC is meant to be used; an SBLC is meant to sit unused.
Neither is universally better. Use a commercial LC when you want the bank to pay on every shipment against documents. Use an SBLC when the buyer will pay directly and you only want protection against default. Many exporters use one or the other depending on trust.
Costs are usually an annual percentage of the SBLC value for issuance, plus advising and, if applicable, confirmation fees. The exact rate depends on the applicant's credit, the tenor and the country risk, so confirm figures with your AD bank.
Only AD banks may issue SBLCs, treated as a non-funded contingent exposure and evaluated like credit. They are issued under the FEMA (Guarantee) Directions to guarantee export performance, following FEDAI guidance on whether ISP98 or UCP applies. RBI's non-fund based directions apply from April 2026.
Both are backup promises paid only on default or non-performance. They are functionally close; the SBLC is the internationally recognised documentary form governed by ISP98, while a bank guarantee is often governed by local law. Overseas buyers frequently prefer the SBLC format.
The common types are financial (secures a payment obligation), performance (secures completion of a task), advance-payment (returns an advance if the seller fails to deliver), and counter (one bank's standby supports another's issuance). Each pays only against the default it names.
