The RBI's regulatory framework for External Commercial Borrowings (ECBs), governed under FEMA 1999, came into focus in early October 2025 amid increasing borrowings by Indian corporates. ECBs operate through Automatic and Approval routes, with mandatory reporting via the Loan Registration Number (LRN) system.

ECBs are permitted for capital expenditure, infrastructure development, and project financing, but cannot be used for real estate speculation, share market investments, or general corporate purposes without specific approval. The framework is significant as Indian firms increasingly tap global debt markets amid favourable interest rate differentials following RBI's repo rate cuts in 2025.
