A balloon loan is a type of debt structure where the borrower makes regular periodic payments — typically lower than they would be on a fully amortising loan of the same tenure — throughout the loan period, with a large lump-sum 'balloon' payment of the remaining outstanding principal due at the end of the loan term. Because regular payments only partially amortise the principal (or cover only interest), a significant portion of the original borrowed amount remains unpaid until maturity. Balloon loans are attractive to borrowers who anticipate having large cash flows in the future (from asset sales, project completions, or business milestones) or who plan to refinance the balloon payment when it comes due. In Indian infrastructure and real estate financing, bullet repayment loans and structured term loans with back-loaded principal repayment function similarly to balloon structures — allowing projects to generate cash flows during the operational phase before making large debt repayments. For equity investors analysing leveraged Indian companies, balloon loan structures create refinancing risk — if the borrower cannot raise funds to repay the balloon amount at maturity, it may default or be forced into distressed refinancing at unfavourable rates.
