TL;DR
The Ministry of Coal published G.S.R. 508(E) on June 22, 2026, formally permitting coal block allottees under the Mines and Minerals (Development and Regulation) Act, 1957 to use an insurance surety bond in place of a performance bank guarantee. Existing PBG holders can also replace their bank guarantee with an insurance surety bond, subject to prescribed conditions.
The amendment applies only to coal blocks allocated under the MMDR Act 1957. Blocks allocated under the Coal Mines (Special Provisions) Act, 2015 are not yet covered; the ministry has confirmed it will process that extension, but no timeline has been set.
An insurance surety bond for coal block performance security must be issued by an IRDAI-licensed insurer for the full performance security amount, naming the same beneficiary as the original PBG, and must comply with the IRDAI (Surety Insurance Contracts) Guidelines 2022, including the 60-month maximum tenure per instrument.
A performance bank guarantee blocks a banking limit and requires collateral tied up for the full guarantee term. An insurance surety bond achieves the same performance security outcome through an insurance contract at a premium of 0.5 to 3% per annum, freeing that capital for mine development and operations.
What Changed Under the Coal Blocks Allocation Amendment Rules 2026?
On June 22, 2026, the Ministry of Coal notified the Coal Blocks Allocation (Amendment) Rules, 2026 in the Gazette of India under G.S.R. 508(E), marking the first time the MMDR Act framework has permitted insurance surety bonds as an alternative to performance bank guarantees for coal block allottees. Before this notification, allottees under the MMDR Act 1957 had one instrument available for performance security: a bank guarantee from a scheduled commercial bank. The amendment adds a second option, an insurance surety bond issued by an IRDAI-licensed insurer.
Two categories of allottees are covered. New allottees can furnish an insurance surety bond in place of a performance bank guarantee when submitting performance security for the first time. Existing allottees who have already submitted a PBG can replace it with an insurance surety bond, subject to prescribed conditions.
The ministry positioned this as an ease-of-doing-business reform. The stated aim is to reduce the financial burden of conventional bank guarantees and enable coal block allottees to direct more capital toward mine development and production.
How Does Performance Security Work in Coal Block Allocation?
When the government allocates a coal block, the allottee must furnish performance security as a financial assurance that development and production milestones will be met within the timeline specified in the allotment agreement. The security remains in force until those obligations are fulfilled.
The required amount varies by block type. For partially explored mines, the performance security amount equals 25% of the estimated exploration expenses under the Mandatory Work Program. Fully explored mines carry a separately stipulated amount based on the individual allotment agreement.
Until the June 2026 amendment, the MMDR Act framework accepted only a bank guarantee from a scheduled commercial bank for this obligation. An insurance surety bond had no legal standing as a performance security instrument under that framework. The June 2026 amendment changes that.

Who Can Use Insurance Surety Bonds Under the 2026 Amendment?
Scope under the amendment is determined by the governing legislation. Any coal block allotment made under the Mines and Minerals (Development and Regulation) Act, 1957 is covered.
CIL Subsidiaries, NMDC, and NLC
Coal India Limited and its seven producing subsidiaries hold coal block allocations under the MMDR Act: SECL (South Eastern Coalfields), BCCL (Bharat Coking Coal), MCL (Mahanadi Coalfields), NCL (Northern Coalfields), ECL (Eastern Coalfields), WCL (Western Coalfields), and CCL (Central Coalfields). All are within scope. NMDC Limited and NLC India Limited also hold MMDR Act allocations and qualify.
The amendment grants these entities the option to switch to an insurance surety bond. It does not require a switch. Finance teams at CIL subsidiaries and other public sector undertakings should assess each active performance security obligation individually to determine where switching makes economic sense. See PSUs accepting insurance surety bonds in India for context on how other PSUs have approached this.
Private and Commercial Coal Block Allottees Under MMDR
Private companies that have won coal blocks through commercial mining auctions or captive block allocations under the MMDR Act are equally covered. Commercial coal mining under the MMDR Act was opened through government-run auction tranches from 2020 onwards. Any allottee from those auctions with an active performance security obligation is eligible under this amendment.
Which Coal Blocks Are Not Yet Covered by the Amendment?
The amendment applies only to blocks allocated under the MMDR Act 1957. Blocks allocated under the Coal Mines (Special Provisions) Act, 2015 are not covered.
The CMSP Act governs coal mines whose allocations were cancelled by the Supreme Court in 2014 and subsequently re-auctioned. Several of India's large, active producing mines fall under this framework, including blocks held by steel and power sector companies. Those allottees cannot yet replace their performance bank guarantees with insurance surety bonds under the June 2026 amendment.
The Ministry of Coal has stated it will "also process for extending the provision to coal blocks allocated under the Coal Mines (Special Provisions) Act, 2015." No timeline has been confirmed as of July 2026. Companies holding CMSP Act blocks should monitor the Gazette of India for a separate notification when that extension is published.
What Requirements Must a Coal Block Insurance Surety Bond Meet?
For an insurance surety bond to validly replace a performance bank guarantee in the coal block context, it must satisfy several conditions.
The bond must be issued for the same amount as the PBG it replaces. The performance security amount is fixed in the allotment agreement and cannot be reduced. The beneficiary named in the insurance surety bond must be the same government authority named in the original allotment agreement, typically the Ministry of Coal or the relevant allotting authority.
The bond must be issued by an insurer licensed by IRDAI to write surety insurance under the IRDAI (Surety Insurance Contracts) Guidelines 2022. Not every general insurer holds this authorization. The IRDAI 2022 guidelines also cap any single insurance surety bond instrument at 60 months. Performance security obligations that extend beyond five years must be structured accordingly, typically through renewal at expiry.
One area where clarity is still needed: the amendment specifies that existing PBG holders can switch "subject to the prescribed conditions," but those conditions are not publicly detailed in news coverage of the notification. Companies should obtain the full text of G.S.R. 508(E) from egazette.gov.in and confirm the specific documentary requirements with the allotting authority or a licensed insurer before initiating a switch.
How Can Coal Block Allottees Replace a PBG With an Insurance Surety Bond?
Step 1: Confirm eligibility: Verify that the coal block is allocated under the MMDR Act 1957, not the Coal Mines (Special Provisions) Act 2015. The governing legislation is stated in the allotment agreement.
Step 2: Review G.S.R. 508(E) and its conditions: The full text of G.S.R. 508(E) is on egazette.gov.in. Review the prescribed conditions to confirm exactly what documentation the allotting authority requires.
Step 3: Confirm the required performance security amount: The insurance surety bond must be issued for the exact amount stipulated in the allotment agreement. Confirm this figure before engaging an insurer.
Step 4: Approach an IRDAI-licensed surety insurer: The application typically requires financial statements, the allotment agreement, project status documentation, and current PBG details. Platforms like axiTrust manage the underwriting workflow digitally, reducing the documentation burden on finance teams.
Step 5: Complete the surety bond underwriting process: The insurer assesses the allottee's financial position and operational status. Active mine developers with clean financials typically move faster through underwriting.
Step 6: Obtain the insurance surety bond: Once issued, the bond covers the same performance security obligation as the PBG it replaces.
Step 7: Submit the bond and request the PBG release: The bond must be formally submitted in accordance with the prescribed conditions. Once the authority accepts the insurance surety bond, the original performance bank guarantee can be returned and the underlying bank limit released.
One caution: do not cancel or allow the existing PBG to lapse before the insurance surety bond has been formally accepted by the allotting authority. The exact sequence for release depends on the prescribed conditions in the gazette notification and the terms of the individual allotment agreement.
Why Should Coal Block Allottees Replace Their PBGs?
A performance bank guarantee ties up capital in one of two ways. The allottee either provides cash collateral against the guarantee, locking those funds for the full term, or the guarantee is issued against a credit facility, which reduces the available working capital limit for mine development, equipment finance, and operations.
An insurance surety bond achieves the same performance security outcome through an insurance contract. The cost is a premium of 0.5 to 3% per annum on the bond value, depending on the insurer's underwriting assessment. The banking limit previously absorbed by the performance bank guarantee is freed entirely.
For mining companies holding multiple coal block allocations under the MMDR Act, the aggregate capital release can be substantial. The ministry's framing of the amendment as enabling allottees to "deploy their capital more efficiently" reflects a straightforward calculation: multiple PBGs, each consuming a banking limit or blocking cash collateral, create a meaningful drag on available capital across an active coal mining portfolio. See bank guarantee alternative in India and insurance surety bond balance sheet for a deeper look at how this plays out on the balance sheet.
What Should Coal Block Allottees Do Next?
The right action depends on which category applies:
If you hold an MMDR Act coal block with an active PBG: Review G.S.R. 508(E) to understand the prescribed conditions and confirm your block's eligibility. Start the insurance surety bond application now. Underwriting takes time, particularly for companies engaging a surety insurer for the first time, and starting early avoids compressing the timeline against your PBG renewal date.
If you are bidding on a new coal block auction under the MMDR Act: Factor insurance surety bonds into your performance security planning from the outset. You no longer need to reserve banking limits specifically for this obligation. Build the premium cost into your project financials instead.
If you hold a CMSP Act 2015 block: The current amendment does not apply. Monitor the Ministry of Coal for a separate gazette notification when the extension to CMSP Act blocks is published.
If you are a CIL subsidiary, NMDC, or NLC: The amendment applies at the block level, not at the entity level. Finance teams should assess each active performance security obligation individually rather than treating this as an entity-wide policy decision.

Frequently Asked Questions
What is G.S.R. 508(E) and where can I find it?
G.S.R. 508(E) is the gazette notification for the Coal Blocks Allocation (Amendment) Rules, 2026, published June 22, 2026. Full text is on egazette.gov.in; the PIB press release (PRID 2280280) has a plain-language summary.
Can a coal block allottee use a partial insurance surety bond and keep a partial PBG for the same obligation?
The amendment permits substitution of the PBG with an insurance surety bond, not partial coverage. The insurance surety bond must cover the full performance security amount. Whether partial instruments are permissible under the prescribed conditions would require confirmation directly from the allotting authority.
Does the amendment change the amount of performance security required?
No. The amendment changes the permitted instrument, not the required amount. The performance security amount remains as stipulated in the allotment agreement and the insurance surety bond must be issued for that exact figure.
If the insurance surety bond is invoked and a claim is paid, does the allottee still owe the insurer?
Yes. An insurance surety bond is a three-party instrument. If the insurer pays a claim to the beneficiary, the insurer holds the right of recovery against the allottee. This is structurally the same as a bank guarantee: the obligation does not disappear on payment; it transfers to the insurer as a recoverable debt. See how an insurance surety bond claim is invoked in India.
