IRDAI Surety Guidelines in forceSince 2011
CA-led, senior on every fileAn Insurance Surety Bond is a three-party guarantee regulated by IRDAI — between the Principal, the Obligee and an IRDAI-licensed insurer. Governed by the IRDAI (Surety Insurance Contracts) Guidelines, 2022, ISBs free up the cash margin and non-fund banking limits a Bank Guarantee would otherwise block — letting you bid wider while the premium sits as an expense, not blocked capital.
Finnova Advisory is an advisory firm — surety bonds are underwritten by IRDAI-licensed insurers; we structure and arrange, we do not underwrite.
What an Insurance Surety Bond is
A three-party guarantee, regulated by IRDAI
An Insurance Surety Bond is a three-party contract between the Principal (contractor or vendor), the Obligee (project owner or government authority) and the Surety (an IRDAI-licensed general insurer). The Surety guarantees that the Principal will perform its contractual obligations — and compensates the Obligee if it does not.
Principal
The contractor or vendor furnishing the bond — freeing margin and banking limits to bid wider.
Surety
The IRDAI-licensed general insurer that underwrites and guarantees performance.
Obligee
The project owner or government authority protected against the Principal’s non-performance.
Governed by the IRDAI (Surety Insurance Contracts) Guidelines, 2022 and progressively liberalised since, ISBs have emerged as a credible, capital-efficient alternative to Bank Guarantees for bid security, performance security, advance payment and retention money obligations.
ISB vs Bank Guarantee
Side-by-side — where the capital is freed
Same job — backing a contractual obligation — but a Bank Guarantee is a banking product that locks cash margin, while an Insurance Surety Bond is an IRDAI-regulated insurance contract that frees it. Here’s the difference that matters to your balance sheet.

See the working capital a surety bond frees up
A Bank Guarantee locks cash margin against your banking limits. An IRDAI surety bond carries no cash margin — so the margin money you would have blocked stays in the business. Move the sliders to size it for your contract.
Working capital freed
≈ ₹7.5 Cr
And the full ₹50 Cr bond value no longer counts against your non-fund-based bank limits.

The bonds we arrange — bid, performance, advance & more
From bid security through to retention release, we match the right bond type and insurer wording to your contract and Obligee.
01
Bid Bond (Bid Security)
Guarantees that a successful bidder will sign the contract and furnish performance security.
02
Performance Bond
Guarantees performance of contractual obligations — the most widely issued ISB in the Indian market.
03
Advance Payment / Mobilisation Bond
Secures recovery of mobilisation advance. NHAI expressly permits ISBs for mobilisation advance in EPC contracts.
04
Retention Money Bond
Enables early release of retention money held by the Obligee, replaced with an insurer-backed guarantee.
05
Contract Bond
Umbrella cover tying bid, performance and payment obligations to a single underlying contract.
06
Customs Bond
Availability as a pure ISB is still limited in India; most duty guarantees remain on BG. Confirmed case-by-case.
Mainstream ISB issuers in India include Bajaj Allianz, Tata AIG, ICICI Lombard, SBI General, New India Assurance and HDFC ERGO.
Why corporates switch
What an ISB does for your business
For contractors, developers and vendors, the shift from BGs to surety bonds is really a working-capital decision — and a growth one.
Keep bank limits free
An ISB doesn’t consume your non-fund-based limits — so your BG capacity stays available for where you genuinely need it.
Bid wider, win more
Capacity to bond several projects at once without blocking capital — so you can tender for more work in parallel.
Faster issuance
Underwriting-led rather than collateral-led — often days, not the weeks a comparable BG can take.
IRDAI-regulated & accepted
Governed by the IRDAI Surety Guidelines, 2022, and placed on par with BGs for NHAI, MoRTH and GFR 2017 public tenders.
Balance-sheet light
Premium is a P&L expense, not blocked capital — healthier liquidity ratios and a cleaner working-capital cycle.
₹5–10 Cr On a ₹100 Cr project, a Bank Guarantee can lock ₹5–10 Cr in cash margin (indicative). An Insurance Surety Bond frees it — capital you can put back into the work. See exactly what yours frees up with our calculator →

BG → ISB switch
Highways EPC · NHAI packages
A highways EPC contractor was blocking crores in FDR margin on performance BGs across active NHAI packages. We moved eligible obligations to ISBs under the June 2023 NHAI circular, releasing working capital that funded the next bid.

A renewable-energy developer needed a mobilisation-advance guarantee on an EPC contract. We shortlisted an insurer whose wording matched the Obligee’s, supported underwriting and coordinated issuance and Obligee acceptance.

FAQ
Insurance surety bonds, answered
Commercially it serves the same purpose, but legally it is a contract of insurance regulated by IRDAI, distinct from a BG regulated under banking law. For government procurement and NHAI/MoRTH projects, ISBs are placed on par with BGs. For private contracts, acceptance depends on the Obligee.
Yes. NHAI first allowed ISBs as bid and performance security across EPC, HAM and BOT (Toll) projects — and for mobilisation advance in EPC contracts — via its circular dated 13 June 2023, since updated and widened by NHAI Policy Circular No. 3.1.41/2025 dated 2 January 2025. Specific tender conditions should still be checked.
Premiums are underwritten on the Principal’s credit profile, bond type, tenor and project risk. Indicative only — Finnova Advisory will obtain firm quotes from shortlisted insurers for your case.
It depends on document readiness and insurer underwriting. For well-rated Principals with complete files, issuance can be faster than a comparable BG.
On default by the Principal, the Obligee invokes the bond per its wording; the insurer pays up to the bond amount and recovers from the Principal under the counter-indemnity executed at issuance.
