  • RBI may move some NBFCs to Top Layer this year

    In the news

    • Nearly two years after introducing a revised regulatory framework for non-banking finance companies (NBFCs), the Reserve Bank of India is set to review the categorisation of NBFCs in 2024.
    • Currently, 16 NBFCs are placed in the upper layer.

    What are Non-Banking Financial Companies (NBFCs)?

    • A NBFC is a company registered under the Companies Act, 1956.
    • It engaged in the business of loans and advances, acquisition of shares/stocks/bonds/debentures/securities issued by Government or local authority or other marketable securities of a like nature, leasing, hire-purchase, insurance business, and chit business.
    • It does NOT include any institution whose principal business is that of agriculture activity, industrial activity, purchase or sale of any goods (other than securities) or providing any services and sale/purchase/construction of immovable property.

    How are NBFCs different from Bank?

    • NBFCs lends and make investments and hence their activities are akin to that of banks.
    • However, there are a few differences as given below:
    1. Commercial Banks are regulated under Banking Regulation Act, 1949.
    2. NBFC CANNOT accept demand deposits.
    3. NBFCs DO NOT form part of the payment and settlement system and cannot issue cheques drawn on itself.
    4. Deposit insurance facility of Deposit Insurance and Credit Guarantee Corporation is NOT available to depositors of NBFCs, unlike in case of banks.

    Different types/categories of NBFCs registered with RBI

    NBFCs are categorized:

    1. in terms of the type of liabilities into Deposit and Non-Deposit accepting NBFCs,
    2. non deposit taking NBFCs by their size into systemically important and other non-deposit holding companies (NBFC-NDSI and NBFC-ND) and
    3. by the kind of activity they conduct.

    Within this broad categorization the different types of NBFCs are as follows:

    Definition
    Asset Finance Company (AFC) A financial institution primarily engaged in financing physical assets used in productive/economic activities, such as automobiles, tractors, machinery, and industrial equipment.
    Investment Company (IC) A company whose principal business involves acquiring securities.
    Loan Company (LC) A financial institution primarily engaged in providing finance through loans, advances, or other means for activities other than its own.

    Does not include Asset Finance Companies.
    Infrastructure Finance Company (IFC) A non-banking finance company that deploys at least 75% of its total assets in infrastructure loans, with a minimum Net Owned Funds of ₹300 crore, a minimum credit rating of ‘A’ or equivalent, and a CRAR of 15%.
    Systemically Important NBFCs NBFCs with an asset size of ₹500 crore or more, as per the last audited balance sheet.

    Considered significant due to their potential impact on the overall financial stability of the economy.

     

    Scale-Based Regulation of NBFCs

    • Scale-based regulations came into effect in October 2021 and were implemented a year later by RBI.
    • There are four layers namely the base layer, middle layer, upper layer and top layer.
    • As on September 30, 2023, NBFCs in the base, middle and upper layers constituted 6 per cent, 71 per cent and 23 per cent of the total assets of NBFCs respectively.
    • Presently, no NBFC is listed in the top layer.

    Here’s a breakdown of the key aspects of the SBR:

    1. Base Layer (NBFC-BL)
    • The Base Layer primarily comprises non-deposit-taking NBFCs with assets below Rs 1,000 crore.
    • It encompasses NBFC Peer to Peer (P2P), NBFC-Account Aggregator (AA), Non-Operative Financial Holding Company (NOFHC), and NBFCs without public funds and customer interface.
    1. Middle Layer (NBFC-ML)
    • The Middle Layer includes deposit-taking NBFCs and non-deposit-taking NBFCs with assets exceeding Rs 1,000 crore.
    • It encompasses NBFCs involved in specific activities such as Standalone Primary Dealers (SPDs), Infrastructure Debt Fund – NBFCs (IDF-NBFCs), Core Investment Companies (CICs), Housing Finance Companies (HFCs), and Infrastructure Finance Companies (NBFC-IFCs).

    III. Upper Layer (NBFC-UL)

    • The Upper Layer comprises NBFCs identified by RBI as requiring enhanced regulatory requirements based on specific parameters and scoring methodology.
    • The top 10 eligible NBFCs in terms of asset size will always be placed in the Upper Layer, irrespective of other factors.
    1. Top Layer (NBFC-TL)
    • NBFCs in the Upper Layer may be transferred to the Top Layer if RBI perceives a significant increase in potential systemic risk.
    • Currently, the Top Layer remains vacant but serves as a precautionary measure for heightened risk situations.
