Bid Bond

A bid bond is a type of surety or bank guarantee that a contractor or supplier submits along with a tender or bid for a project — providing the project owner (often a government body or large corporation) with financial assurance that the bidding entity will enter into the contract and furnish the required performance and payment bonds if its bid is accepted. If the winning bidder refuses to proceed with the contract or fails to provide the required performance securities after their bid is accepted, the project owner can claim the bid bond amount as compensation for the delay and cost of re-tendering. Bid bonds are typically 2% to 5% of the total bid value. In India, bid bonds are routinely required for government infrastructure tenders — including those issued by NHAI (National Highways Authority of India), railways, defence procurement, and public sector power projects — and are issued by commercial banks in the form of bank guarantees or by insurance companies as surety bonds. For equity investors analysing Indian engineering, construction, and infrastructure companies (EPC contractors), the volume and value of active bid bonds outstanding is an indicator of the company's tender pipeline and potential order book growth — though a high ratio of bid bonds to equity capital can signal stretched working capital.
