What Is the Minimum Average Maturity Period?
The Minimum Average Maturity Period (MAMP) is the shortest weighted average tenor that an External Commercial Borrowing (ECB) is allowed to carry under India's foreign exchange rules. It sets a floor on how quickly a foreign-currency or rupee loan raised by an Indian borrower from a non-resident lender can be repaid — the loan cannot be structured to mature, on a weighted-average basis, faster than the MAMP for its category.
Since 16 February 2026, the general MAMP for ECB is three years. A narrower band of one to three years is available only to borrowers in the manufacturing sector, and only up to a capped amount outstanding. Before this reform, ECB raised from a lender that was also a direct or indirect equity holder in the borrower carried a longer, five-year MAMP; that separate five-year rule no longer exists.
Legal Basis
ECB is regulated under the Foreign Exchange Management Act, 1999 (FEMA), through the Foreign Exchange Management (Borrowing and Lending) Regulations, 2018. Schedule I to those Regulations — which carries the ECB framework, including MAMP — was substituted in full by Notification FEMA 3(R)(5)/2026-RB dated 9 February 2026, with effect from 16 February 2026. MAMP itself sits in paragraph 6 of the substituted Schedule I, headed "Maturity."
Paragraph 6(1) states the general rule directly: "An eligible borrower shall raise ECB with minimum average maturity period (MAMP) of three years." That single sentence replaced what had been a layered table of differentiated minimums depending on the lender relationship, the amount, and the end-use — the pre-2026 Master Direction table of differentiated MAMPs no longer describes current law and should not be used for a loan structured after 16 February 2026.
The Three-Year Rule in Practice
"Average maturity period" is a weighted calculation, not the final repayment date; the Explanation to paragraph 6(1) directs that it "shall be computed in a manner illustrated in the Annex I to these Regulations." If an ECB is repaid in a single bullet payment at the end of year three, the average maturity is three years and the rule is satisfied. If the same loan is repaid in installments — some earlier, some later — the weighted average of all the repayment dates, weighted by the amount repaid on each date, must still work out to at least three years. A loan with a large early principal repayment can therefore fail the three-year test even if its final installment falls well after the three-year mark, because the early repayments pull the weighted average down.
Paragraph 6(3) adds a related constraint on optionality: call and put options embedded in the ECB — rights that let the borrower prepay or the lender demand early repayment — cannot be exercised before the MAMP is completed. A three-year loan with a put option exercisable in year two would not comply, because exercising the option would shorten the effective maturity below three years.
The Manufacturing-Sector Carve-Out
Paragraph 6(2) creates the one general exception to the three-year floor. It reads: "An eligible borrower engaged in manufacturing sector may also raise ECB with average maturity period between one year and three years, subject to the condition that outstanding amount of such ECBs shall not exceed USD 150 million." Two conditions apply together — the borrower must be engaged in manufacturing, and the outstanding stock of ECB raised under this shorter-maturity window is capped at USD 150 million per borrower, not per loan. A manufacturing company can raise several ECBs under the one-to-three-year band, but the combined outstanding amount under that band cannot exceed the cap; any ECB raised above the cap reverts to the standard three-year MAMP.
This carve-out matters most for manufacturers financing working capital or short-cycle capital expenditure — equipment with a useful life shorter than three years, or a production ramp-up that will be repaid from cash flows generated well inside the three-year mark. Without the carve-out, such borrowers would either have to accept a mismatch between loan tenor and asset life, or find funding elsewhere.
When MAMP Does Not Apply
Paragraph 6(4) provides that "The MAMP specified at sub-paragraph (1) and (2) shall not be required to be met in case of –", and then lists five situations. They are quoted here in full, because each turns on wording a paraphrase tends to lose:
- "Conversion of ECB (including FCCB and FCEB) to non-debt instruments in accordance with the rules and regulations issued under the Act";
- "Repayment of ECB using the proceeds from non-debt instruments issued in terms of Foreign Exchange Management (Non-Debt Instrument) Rules, 2019 on repatriation basis, provided the proceeds are received after the drawdown of the ECB";
- "Refinance of ECB in terms of these Regulations";
- "Waiver of debt by the lender"; and
- "Repayment of ECB, if required, for undertaking corporate actions such as closure, merger, demerger, arrangement, acquisition of control, amalgamation, resolution or liquidation by the lender or the borrower."
Two of the five carry conditions that are easy to miss. The first covers conversion of the ECB itself into a non-debt instrument, not the use of ECB proceeds to buy one. The second applies only where the non-debt instrument proceeds are raised on a repatriation basis and are received after the ECB has been drawn down. In each of the five, the underlying transaction extinguishes or converts the debt on terms the maturity rule was never designed to police, so the regulation lets the transaction proceed without checking the weighted-average tenor.
MAMP Inside the Rest of the ECB Framework
MAMP does not operate in isolation — it is one of several thresholds in the substituted Schedule I that a foreign lender or an Indian borrower must read together:
- Borrowing limit (paragraph 5(1)): an eligible borrower may raise ECB up to the higher of (a) USD 1 billion outstanding, or (b) 300% of net worth per the last audited standalone balance sheet, counting both external and domestic outstanding borrowing. This limit does not apply to borrowers regulated by a financial-sector regulator.
- Cost ceiling (paragraph 7): for ECB that meets the three-year MAMP, the all-in cost is no longer capped by a fixed spread — it must simply be "in line with prevailing market conditions." An ECB carrying a MAMP shorter than three years (i.e., a manufacturing-sector loan under paragraph 6(2)) must instead keep its cost within the Trade Credit cost ceiling.
- Prepayment and penal charges (paragraph 8): these, too, must be "in line with prevailing market conditions" rather than a fixed cap.
- Reporting (paragraph 16): receipt of ECB proceeds and debt servicing is reported on Form ECB 2, filed through the borrower's Authorized Dealer bank, due within seven calendar days from the end of the month in which the proceeds were received or the debt was serviced.
A borrower who gets MAMP right but misses the linked cost ceiling for a sub-three-year manufacturing loan, or files Form ECB 2 late, is still non-compliant — MAMP is a necessary check, not a sufficient one.
Why MAMP Matters for Foreign Companies and Lenders
For a foreign investor financing an Indian subsidiary, MAMP determines whether debt or equity is the cheaper route for a given time horizon. A parent company wanting to fund a subsidiary for eighteen months of working capital cannot use an ordinary ECB — the three-year floor would force a longer tenor than needed, tying up the parent's balance sheet and creating an early-repayment problem if the subsidiary's cash position improves faster than expected. The subsidiary would need to look at rupee-denominated working-capital facilities from Indian banks, trade credit, or (if it qualifies) the manufacturing carve-out instead.
For a non-resident lender — a foreign bank, a private credit fund, or the parent itself acting as lender — the MAMP shapes the loan documentation from day one: the repayment schedule must be weighted-average tested against three years (or one year for a qualifying manufacturer) before the loan is drawn, not adjusted afterward. Structuring a loan with early bullet repayments to reduce the borrower's effective cost of capital, without checking the weighted-average test, is one of the more common ways foreign lenders inadvertently put an Indian borrower in breach.
Because the five-year MAMP that used to apply specifically to ECB from a foreign equity holder has been removed, a parent-to-subsidiary loan is now tested against the same three-year floor as a loan from an unrelated foreign bank. This simplifies structuring for foreign parent companies that fund their Indian subsidiaries directly, since the lender relationship no longer changes the maturity math.
Worked Example
A US manufacturing parent lends its Indian subsidiary USD 20 million to fund a new production line. If the subsidiary is engaged in manufacturing and this is its only ECB under the shorter-maturity window, the loan can be structured with an average maturity of two years under paragraph 6(2), because USD 20 million is well within the USD 150 million cap. The loan's cost must still fall within the Trade Credit cost ceiling, since its MAMP is under three years. If the same parent later lends the subsidiary a further USD 140 million under the same window, the combined outstanding of USD 160 million would breach the USD 150 million cap — the excess USD 10 million would need to be restructured with a three-year MAMP under paragraph 6(1) instead, or reduced to bring the manufacturing-window outstanding back under the cap.
Common Mistakes
- Citing the pre-2026 Master Direction MAMP table. The tiered minimums set out in the earlier Master Direction on External Commercial Borrowings no longer apply to ECB structured after 16 February 2026 — Schedule I was substituted, not amended in place.
- Assuming the five-year equity-holder MAMP still applies. ECB from a lender that is also a direct or indirect equity holder in the borrower is no longer subject to a separate, longer MAMP. It is tested against the same three-year (or manufacturing one-to-three-year) rule as any other ECB.
- Testing MAMP against the final repayment date instead of the weighted average. A loan can have a final installment well past three years and still fail MAMP if early repayments pull the weighted average below three years.
- Treating the manufacturing carve-out as unlimited. The one-to-three-year band is capped at USD 150 million outstanding per borrower — not per loan, and not a one-time check.
- Exercising a call or put option before MAMP completion. Paragraph 6(3) blocks this regardless of what the loan documentation says.
Frequently Asked Questions
What is the current MAMP for a standard ECB in India?
Three years, under paragraph 6(1) of Schedule I to the Foreign Exchange Management (Borrowing and Lending) Regulations, 2018, as substituted by Notification FEMA 3(R)(5)/2026-RB with effect from 16 February 2026. This replaced the earlier tiered structure that set different minimums depending on the lender, amount, and end-use of the ECB.
Can any Indian company raise ECB with a maturity shorter than three years?
Only a borrower engaged in the manufacturing sector, under paragraph 6(2), and only up to USD 150 million outstanding under that shorter one-to-three-year window. Any manufacturing ECB above that cap, and any ECB raised by a non-manufacturing borrower, must meet the standard three-year MAMP.
Does ECB from a foreign parent company still carry a five-year MAMP?
No. The pre-2026 rule requiring a five-year MAMP for ECB raised from a lender that was also a direct or indirect equity holder has been removed. A parent-to-subsidiary ECB is now tested against the same three-year (or manufacturing one-to-three-year) rule as ECB from any other eligible lender.
How is "average maturity period" actually calculated?
It is the weighted average of all scheduled repayment dates, weighted by the amount repaid on each date — not simply the date of the final installment. The Explanation to paragraph 6(1) points to the worked illustration in Annex I to the Regulations. A repayment schedule front-loaded with large early installments can produce a weighted average below three years even if the last installment falls after the three-year mark, putting the loan in breach of paragraph 6(1).
What happens if an ECB does not meet the MAMP for its category?
The Regulations do not permit an ECB to be raised without complying with the applicable MAMP, so a proposed repayment schedule that fails the weighted-average test needs to be restructured before drawdown. The Authorized Dealer bank through which the ECB is reported checks compliance with Schedule I, including MAMP, as part of processing the loan and the related Form ECB 2 filings.
