What is ECB (External Commercial Borrowing)?

How it works

ECB is governed by limits on amount, end-use, minimum maturity and all-in cost, under the automatic or approval route, with reporting in Form ECB and monthly ECB-2 returns.

The framework in operating terms

The 2019 ECB framework collapsed the earlier track structure into two categories — foreign-currency-denominated ECB and Indian-rupee-denominated ECB — and widened eligibility to any entity eligible to receive FDI. Recognised lenders must be residents of FATF or IOSCO compliant jurisdictions, which quietly excludes several traditional funding routes. The automatic route permits up to US$750 million or equivalent per financial year, with anything beyond that, or any deviation from the prescribed parameters, requiring RBI approval.

The four parameters that decide feasibility

Every ECB proposal is tested against minimum average maturity, all-in-cost ceiling, end-use and lender eligibility. Minimum average maturity is generally three years, with shorter or longer periods prescribed for specific categories and end-uses. The all-in-cost ceiling is the benchmark rate plus 500 basis points, and all-in-cost is defined widely enough to capture arrangement and guarantee fees, not merely coupon. End-use restrictions are where most structures fail: on-lending, real estate activity, capital-market investment and equity acquisition sit outside the permitted list except in narrow carve-outs.

Worked example and the compliance rhythm

An Indian manufacturer borrows US$20 million from its overseas parent for capital expenditure. Because the parent qualifies as a recognised lender and capex is a permitted end-use, the automatic route applies. Before drawdown the borrower files Form ECB through its authorised dealer bank and obtains a Loan Registration Number — no money may be drawn without it. Thereafter Form ECB-2 is filed monthly for the life of the loan. Hedging expectations apply to certain borrowers, and the natural-hedge position is best documented at sanction rather than reconstructed later. Late filing of Form ECB-2 is normally regularised through Late Submission Fees, but a drawdown made before the Loan Registration Number is allotted is a substantive contravention that has to be compounded.
