Why Surety Bonds Are Becoming Increasingly Relevant for Infrastructure & EPC Projects

by Jackson Jacob, Chief Distribution Officer, Zuno General Insurance

India’s infrastructure story is entering a defining decade. From highways and rail corridors to airports, renewable energy projects, logistics hubs and industrial corridors, the scale of investments underway is unprecedented. But as projects become larger and more complex, financing them is no longer just about raising capital, it is equally about managing contractual risk efficiently.
That is where the conversation around surety bonds is beginning to change. For years, bank guarantees have been the default instrument for securing infrastructure and EPC contracts. They have served the industry well, but today’s infrastructure ambitions demand a broader ecosystem of financial solutions. Contractors need to execute multiple projects simultaneously, preserve liquidity and remain competitive, while project owners require confidence that contractual obligations will be fulfilled. Balancing these two objectives is becoming increasingly critical, and surety bonds offer an effective way to achieve that balance.
A surety bond is a three-party agreement between the contractor, the insurer and the project owner, under which the insurer guarantees the contractor’s contractual performance. Unlike traditional bank guarantees, which often require contractors to lock up collateral or utilise sanctioned credit limits, surety bonds enable businesses to preserve valuable working capital without compromising the financial security expected by project owners.

The opportunity for surety bonds has grown alongside India’s infrastructure ambitions. The Union Budget 2026-27 has allocated ₹12.2 lakh crore towards capital expenditure, while programmes such as the National Infrastructure Pipeline and PM Gati Shakti continue to accelerate investments across transport, energy, urban development and manufacturing. As thousands of public infrastructure contracts are awarded over the coming years, the need for efficient risk-transfer mechanisms will only become more pronounced.

Encouragingly, the ecosystem is evolving to support this shift. Since the introduction of the IRDAI (Surety Insurance Contracts) Guidelines in 2022, subsequent regulatory reforms have expanded underwriting flexibility, simplified regulations and encouraged wider acceptance of insurance surety bonds across government procurement. The market has responded positively. More than 3,300 Insurance Surety Bonds have already been issued across India, with an aggregate value exceeding ₹29,000 crore, reflecting growing confidence in the product across the infrastructure ecosystem.

However, the growing relevance of surety bonds is not driven by regulation alone. It is driven by economics. Infrastructure projects typically require multiple guarantees throughout their lifecycle, from bid security and performance guarantees to advance payment and retention guarantees. For contractors executing several projects simultaneously, these obligations can consume a substantial portion of available banking limits. The result is often reduced financial flexibility at precisely the time businesses need capital to mobilise projects, invest in equipment and pursue new opportunities.

Surety bonds help address this challenge by complementing, rather than replacing, the traditional banking system. They diversify the sources of contractual security available to contractors, allowing banking relationships and credit facilities to be utilised for operational and business growth requirements instead of being tied up solely for performance guarantees. In a sector where execution speed and financial agility increasingly determine competitiveness, that flexibility can make a meaningful difference.
Equally important is the discipline that surety bonds introduce into project execution. Unlike a purely financial instrument, every surety bond is supported by detailed underwriting that evaluates a contractor’s financial strength, technical capabilities, project execution record and risk profile before the bond is issued. This additional layer of due diligence benefits the entire ecosystem by reinforcing contractor credibility while giving project owners greater confidence in project delivery.

The market is already demonstrating how this model can scale. Government agencies have steadily expanded the acceptance of insurance surety bonds, with the National Highways Authority of India emerging as one of the country’s largest adopters. Such acceptance is helping establish market confidence and creating momentum for wider adoption across public infrastructure projects.
As India’s engineering and construction sector continues to grow, financing solutions must evolve alongside it. The future is unlikely to be defined by choosing between bank guarantees and surety bonds. Instead, it will be shaped by creating a more diversified and resilient guarantee ecosystem, where each instrument plays to its strengths. Surety bonds are increasingly becoming an important part of that ecosystem by improving liquidity, strengthening contractual discipline and enabling more efficient capital allocation.

Looking Ahead
India’s infrastructure ambitions will require not only record investments but also smarter financial mechanisms that support timely project execution and sustainable growth. Surety bonds are steadily moving beyond being viewed as an alternative to bank guarantees to becoming an integral part of the country’s infrastructure financing framework. As regulatory support strengthens, market awareness grows and adoption expands across public and private sector projects, surety bonds have the potential to improve liquidity for contractors, strengthen confidence for project owners and contribute meaningfully to the efficient delivery of India’s next generation of infrastructure.
