Capital inflows are a major tool of development policy. Historically, lack of sufficient domestic capital has led the government and firms to seek foreign capital. Foreign capital means money drawn from abroad to finance investment domestically. Major categories of foreign capital include Foreign Direct Investment (FDI), NRI deposits and External Commercial Borrowings (ECBs). ECBs are an important source of external finance for corporates, public sector undertakings and infrastructure projects.
External Commercial Borrowing (ECB) refers to commercial loans, credit facilities or debt instruments raised from foreign lenders by residents (companies, institutions and sometimes government entities) for financing activities in the country. ECBs are not intended to be traded on Indian stock exchanges.
Minimum average maturity: ECBs are normally required to have a minimum average maturity of three years.

The regulatory framework for overseas borrowing has been revised repeatedly by the Reserve Bank of India (RBI) and the Government to keep pace with changes in the domestic and global financial environment. Rules have been adapted to balance access to international finance with macro-financial stability and exchange-rate risks.
ECBs have become a major form of foreign capital, often complementing FDI. They have typically contributed a significant share of total capital inflows into the country.
ECBs are governed by a two-track access mechanism: the Automatic Route and the Approval Route. The principal regulators and administrators are:
The main aim of ECB policy is to encourage longer maturities and to finance important sectors so as to support overall economic growth.
The RBI keeps limits and conditions under the automatic route and approval route. The automatic route borrowing limit has been set at $750 per financial year under the existing provisions, with sector-wise limits replaced by consolidated access conditions.
The all-in-cost ceiling is prescribed as a spread over an applicable benchmark. The prescribed ceiling is 450 basis points per annum over 6-month LIBOR or the applicable benchmark rate for the respective currency.
What is All-in-Cost? All-in-cost includes the interest rate plus other fees and charges such as processing fees, arrangement fees, guarantee fees and Export Credit Agency (ECA) charges, whether paid in foreign currency or in Indian rupees. In formula form:
ECBs are subject to end-use prescriptions. Borrowings may not be used for certain activities. The negative list includes:
To limit currency risk arising from foreign currency borrowings, hedging conditions are prescribed for certain ECBs.
Hedging typically means taking positions in instruments such as currency forward contracts, options or swaps to reduce the risk of adverse movements in the exchange rate. Mandatory hedging ensures a significant portion of the foreign currency exposure is protected for the specified hedging period.
Under the Automatic Route, eligible borrowers can enter into loan agreements with recognised foreign lenders and then register the transaction with the RBI. No prior approval from the government or RBI is required for eligible transactions within specified limits and conditions.
Under the Approval Route, the borrower submits an application through an authorised dealer bank to the RBI or the designated authority for prior approval. This route applies where the borrowing or the end-use falls outside the automatic route limits or conditions.
The following classes of borrowers are generally eligible to raise ECBs under either route, subject to conditions and sectoral prescriptions:

ECBs can support large capital projects and lower the cost of borrowing for corporations because international rates may be more favourable than domestic rates. Key impacts include:
Demand for ECBs may increase because of:
ECBs are an important source of external finance for a vibrant corporate and infrastructure sector. They allow firms to access large-scale, often lower-cost funds internationally when domestic markets cannot provide similar tenors or volumes. At the same time, careful regulation of end-uses, maturities, hedging and all-in-cost ceilings is essential to manage currency and external sector risks.
