RBI Overhauls IDF-NBFC Rules: Higher Capital, More Flexibility
Current · Source: Reserve Bank of India · RBI/2023-24/54 · issued 18 Aug 2023 · ~2 min read
Quick answerRBI has revised IDF-NBFC regulations, effective August 18, 2023. Key changes include a higher minimum net owned funds of ₹300 crore, a 15% CRAR, removal of the sponsor requirement, optional tripartite agreements, and new fund-raising flexibility via short-term bonds and CPs up to 10% of borrowings.
The rule, in the simplest words
IDF-NBFCs (companies that lend money for big projects like roads or bridges) must have at least ₹300 crore of their own money (net owned funds).
They must keep a safety cushion of 15% of their loans as capital (CRAR), with at least 10% being top-quality capital (Tier 1).
They no longer need a sponsor (a bank or big NBFC) to start, and they don't have to sign a tripartite agreement (a three-party deal) for PPP projects (public-private partnerships).
They can now raise up to 10% of their total borrowings using short-term bonds or commercial papers (like IOUs that are paid back quickly) to better match their money with project timelines.
They can also borrow from abroad (ECBs) for at least 5 years, but not from foreign branches of Indian banks.
How it plays out — a real example
A forex & trade-finance officer in Indore, Priya, works for an IDF-NBFC that funds toll roads. After the new rule, her company no longer needs a sponsor bank, so she can approve a loan for a new highway project without waiting for a big bank's sign-off. Also, she can now issue short-term commercial papers to cover a 6-month cash gap, making it easier to pay contractors on time.
What changed
The minimum net owned funds for IDF-NBFCs has been raised to ₹300 crore, and the capital adequacy ratio is now 15% with a 10% Tier 1 capital floor. The requirement for a sponsor (bank or NBFC-IFC) has been withdrawn, and tripartite agreements for PPP projects are now optional. IDF-NBFCs can now raise up to 10% of total borrowings through shorter tenor bonds and commercial papers, and can also use ECB loans (minimum 5-year tenor, not from foreign branches of Indian banks).
What it means for you
These changes aim to strengthen the financial health of IDF-NBFCs while giving them more operational flexibility. The higher capital requirements will likely lead to consolidation among smaller players, but the removal of sponsor and tripartite agreement mandates reduces entry barriers and operational costs. The new fund-raising options improve asset-liability management, enabling IDF-NBFCs to better match short-term liabilities with infrastructure project cash flows.
What you must do
Review and adjust capital planning to meet the new ₹300 crore NOF and 15% CRAR requirements immediately.
Update internal policies to reflect the removal of sponsor and tripartite agreement requirements for new investments.
Assess fund-raising strategies to utilize the new 10% short-term bond/CP limit and ECB route for better ALM.
Ensure compliance with risk-weighting norms as per NBFC-ICC guidelines for all assets.
If sponsoring an IDF-MF, verify eligibility against the new conditions (NOF, CRAR, NPA, profitability, track record, and minimum 5 years of existence).
Who it affects
All existing and prospective IDF-NBFCs, NBFCs looking to sponsor IDF-Mutual Funds, Infrastructure project developers and concessionaires, Banks and financial institutions lending to or investing in IDF-NBFCs

All Infrastructure Debt Fund-NBFCs (IDF-NBFCs)
Dear Sir/ Madam,
Review of Regulatory Framework for IDF-NBFCs
In order to enable IDF-NBFCs to play a greater role in the financing of the infrastructure sector and to harmonise the regulations governing financing of infrastructure sector by the NBFCs, a review of the guidelines applicable to IDF-NBFCs has been undertaken, in consultation with the Government of India.
2. The revised regulatory framework for IDF-NBFCs is provided in the Annex . These guidelines shall come into effect from the date of this circular.
Yours faithfully,
(J.P. Sharma)
Chief General Manager
Annex
An IDF is set up either as a trust or as a company. A trust based IDF is registered as an IDF-Mutual Fund (IDF-MF) and is regulated by the Securities and Exchange Board of India (SEBI) whereas a company based IDF is registered as an IDF-NBFC and is regulated by the Reserve Bank of India (RBI).
2. Definition
An IDF-NBFC means a non-deposit taking NBFC which is permitted to – (i) refinance post commencement operations date (COD) infrastructure projects that have completed at least one year of satisfactory commercial operations; and (ii) finance toll operate transfer (TOT) projects as the direct lender.
3. Net owned funds (NOF) and regulatory capital
An IDF-NBFC shall be required to have an NOF of at least ₹300 crore and capital-to-risk weighted assets ratio (CRAR) of minimum 15 per cent (with minimum Tier 1 capital of 10 per cent).
4. Raising of funds
(i) IDF-NBFC shall raise funds through issue of either rupee or dollar denominated bonds of minimum five-year maturity. With a view to facilitate better asset-liability management (ALM), IDF-NBFCs can raise funds through shorter tenor bonds and commercial papers (CPs) from the domestic market to the extent of up to 10 per cent of their total outstanding borrowings.
(ii) In addition to the bond route, IDF-NBFCs can also raise funds through loan route under external commercial borrowings (ECBs). However, such borrowings shall be subject to minimum tenor of five years and the ECB loans should not be sourced from foreign branches of Indian banks.
(iii) Regarding ECBs, IDF-NBFCs shall also be required to adhere to the guidelines issued by the Foreign Exchange Department of the RBI.
5. Exposure limits
The exposure limits for IDF-NBFCs shall be 30% of their Tier 1 capital for single borrower/ party and 50% of their Tier 1 capital for single group of borrowers/ parties.
6. Risk weights
For computing CRAR of the IDF-NBFCs, their assets shall be risk-weighted as per risk-weights applicable to NBFC-Investment and Credit Companies (NBFC-ICCs).
7. Requirements of a sponsor and tripartite agreement
7.1 Under the earlier guidelines, an IDF-NBFC was required to be sponsored by a bank or an NBFC-Infrastructure Finance Company (NBFC-IFC). The requirement of a sponsor for an IDF-NBFC has now been withdrawn and shareholders of IDF-NBFCs shall be subjected to scrutiny as applicable to other NBFCs, including NBFC-IFCs.
7.2 Earlier, IDF-NBFCs were required to enter into a tripartite agreement with the concessionaire and the project authority for investments in the Public Private Partnership (PPP) infrastructure projects having a project authority. The requirement of the tripartite agreement has now been made optional.
8. Other regulatory norms
All other regulatory norms including income recognition, asset classification and provisioning norms as applicable to NBFC-ICCs shall be applicable to IDF-NBFCs.
9. Guidelines governing sponsorship of IDF-MFs by NBFCs
9.1 All NBFCs shall be eligible to sponsor (sponsorship as defined by SEBI Regulations for Mutual Funds) IDF-MFs with prior approval of the RBI subject to the following conditions (based on the audited financial statements), in addition to those prescribed by SEBI:
(i) The NBFC shall have a minimum NOF of ₹300 crore and CRAR of 15 percent;
(ii) Its net NPAs shall be less than 3 per cent of the net advances;
(iii) It shall have been in existence for at least 5 years;
(iv) It shall be earning profits for the last three years and its performance shall be satisfactory;
(v) The CRAR of the NBFC post investment in the IDF-MF shall not be less than the regulatory minimum prescribed for it;
(vi) The NBFC shall continue to maintain the required level of NOF after accounting for investment in the proposed IDF-MF;
(vii) There shall be no supervisory concerns with respect to the NBFC.
9.2 NBFCs that fulfil the eligibility criteria as above shall approach the Department of Regulation of the RBI, for prior approval to sponsor IDF-MFs.
