Retail Individual Investor (RII)

From WebNotes, a public knowledge base. Last updated . Reading time ~12 min.

A Retail Individual Investor (RII) is a natural person who applies for shares in a public issue in India for an aggregate application value not exceeding ₹2,00,000, and who is not a Qualified Institutional Buyer (QIB) or a Non-Institutional Investor (NII). The category is defined in Regulation 2(vv) of the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 (SEBI ICDR). In a mainboard Initial Public Offering (IPO) conducted through the book-building route, at least 35 per cent of the net public offer is reserved for the RII category, making it by far the most widely recognised investor segment in the Indian primary market.

The retail category occupies a distinct position in the regulatory architecture of the Indian IPO: it is the only category for which a mandatory minimum allotment of one lot is guaranteed to each successful applicant when the issue is oversubscribed, and it is the only category for which the Unified Payments Interface (UPI) ASBA route is the prescribed application mechanism through broker intermediaries. The ₹2,00,000 ceiling, which has remained unchanged since SEBI introduced the current ICDR framework in 2018, simultaneously defines the category and limits the maximum position any single retail applicant can hold at the subscription stage.

Regulatory definition and scope

Regulation 2(vv) of SEBI ICDR 2018 states: “retail individual investor means an investor who applies or bids for specified securities for a value of not more than two lakh rupees.” The simplicity of the definition belies its operational significance. Three elements are worth unpacking.

First, the threshold is applied per-application, not per-person per-issue. A person who submits two applications in the same IPO from the same Permanent Account Number (PAN) will have both applications rejected by the registrar because duplicate bids from the same PAN are not permitted. One PAN, one application is the effective rule.

Second, the definition captures the bid value at the time of application, calculated at the cut-off price option if the applicant selects cut-off pricing, or at the price the applicant specifies if placing a price bid within the price band. If an applicant bids at the upper end of the band and the lot size is such that a single lot costs, say, ₹14,000, they can apply for at most 14 lots (₹1,96,000 at ₹14,000 each, still within the ₹2,00,000 cap), but not 15 lots (₹2,10,000, which would exceed the cap and reclassify the bid as NII).

Third, the definition is not linked to income, net worth, or any other financial criterion. A retail investor is defined solely by bid size. A high-net-worth individual who chooses to bid within the ₹2,00,000 ceiling participates as an RII and receives the protections, and limitations, of that category.

Non-Resident Indians (NRIs) applying on a non-repatriation basis through NRO accounts at amounts up to ₹2,00,000 also qualify as RIIs, subject to the exchange-control conditions described in the Non-Resident Indian article. NRIs applying on a repatriation basis, or through the Portfolio Investment Scheme, are treated as NIIs regardless of bid amount under certain interpretations; the precise treatment depends on the particular issue’s terms and the Self Certified Syndicate Bank (SCSB) through which the application is routed.

Allocation in a mainboard IPO

Under Schedule XIII of SEBI ICDR 2018, the minimum allocation to the retail category in a mainboard book-built public issue is 35 per cent of the net public offer. The net public offer is the total issue size minus any amount reserved for existing shareholders in an offer-for-sale component, employees, shareholders of a promoter group company, and similar reserved portions. In a typical ₹1,000 crore mainboard IPO with no reservations, at least ₹350 crore worth of shares must be offered to RIIs.

The 35 per cent figure is a floor, not a ceiling. If the QIB portion is undersubscribed and the issue is not fully subscribed through the mandatory QIB channels, the undersubscribed portion does not automatically flow to the RII bucket; SEBI rules specify that the QIB portion cannot be undersubscribed without the entire book-built issue failing. Conversely, if the RII portion itself is undersubscribed, the unsubscribed shares can be allocated to the NII category or the QIB category under the spill-over rules in Regulation 49 of SEBI ICDR 2018.

For SME IPOs conducted on the BSE SME or NSE Emerge platforms, the allocation rules differ materially: SEBI mandates that at least 35 per cent of the net public offer be reserved for the RII category, but the minimum application size in an SME IPO is typically ₹1,00,000 or more (set by the exchange and the company), and the lot sizes are correspondingly larger, which in practice means fewer retail applicants can participate in SME issues compared with mainboard issues.

Application mechanism: UPI ASBA

Since Phase II of the UPI ASBA rollout, which became mandatory for broker-intermediated retail applications from 1 July 2019, the prescribed application route for RIIs applying through stockbrokers and registered investment advisors is UPI ASBA . The flow is as follows.

  1. The investor opens the IPO application on their broker’s platform, for example, the Bids section of Kite for Zerodha customers.
  2. The investor selects the number of lots, the price (or cut-off), and enters their UPI Virtual Payment Address (VPA).
  3. The broker transmits the bid to the stock exchange, which forwards a UPI collect request to the investor’s bank via the NPCI UPI switch.
  4. The investor approves the mandate on their UPI-enabled banking app within the stipulated time window. The bank then blocks, but does not debit, the application amount.
  5. The amount remains blocked throughout the subscription period and until the basis of allotment is finalised by the registrar.
  6. On the allotment date (T+1 after issue closure under the T+3 regime), the registrar instructs the SCSB to debit only the amount corresponding to allotted shares. The block on the unallotted portion is released immediately.

RIIs can alternatively apply through the bank ASBA via NetBanking route offered by their SCSB, which does not require a UPI VPA and suits applicants whose bank accounts are not linked to a UPI handle. The bank ASBA route has been available since 2008 and pre-dates the UPI mechanism; it remains fully valid for retail applicants.

The UPI mandate cap relevant to retail IPO applicants was raised from ₹2,00,000 to ₹5,00,000 by NPCI in September 2025. This does not change the ₹2,00,000 RII category ceiling (which is set by SEBI, not NPCI); rather, it provides headroom should SEBI elect to revise the threshold upward in a future ICDR amendment, and it also accommodates the ₹5,00,000 limit relevant to the NII category when NII applicants use UPI mandates.

Allotment rules when the retail category is oversubscribed

The allotment methodology for the RII category in an oversubscribed mainboard IPO is unique in the Indian primary market and is specified in Schedule XIII, Part B, Clause 5 of SEBI ICDR 2018. The process follows a two-step approach.

Step 1, Minimum allotment of one lot. Each valid application in the RII category is entitled to receive at least one lot (the minimum bid lot for the issue), provided the total number of applicants is fewer than the number of lots available in the RII portion. If the total RII demand, expressed as the number of valid applications, exceeds the number of available lots divided by the minimum lot size, the registrar moves to a lottery.

Step 2, Computerised proportionate lottery. The registrar runs a computerised draw in which each valid application (not each lot bid for) receives one lottery ticket. The available lots are distributed such that each winning application receives exactly one lot. Applications that do not win the lottery receive zero allotment. This mechanism means that in a heavily oversubscribed IPO, a person who bids for one lot has the same probability of winning as a person who bids for the maximum allowable number of lots. Bidding for more lots does not improve the odds of receiving at least one lot; it only increases the potential allotment if the issue is less oversubscribed than the maximum RII subscription that would trigger the pure lottery.

The rationale for this rule is investor democratisation: SEBI designed the RII category to ensure that small individual applicants are not systematically disadvantaged by larger applicants who can afford to place bigger bids within the ₹2,00,000 ceiling. The one-application-one-ticket lottery is the operational expression of that intent.

Proportionate allotment below maximum subscription. When the RII oversubscription ratio is low enough that all applicants can receive at least one lot but not all can receive their full bid quantity, the registrar applies proportionate allotment rounding to the nearest lot, with a minimum guaranteed allotment of one lot per valid application.

The basis of allotment document published by the registrar after an IPO sets out the number of valid applications received, the total shares applied for in the RII category, the ratio used (e.g. 1:14 meaning one lot allotted for every 14 applications), and the total number of applications that received an allotment.

Cut-off price option

Retail individual investors, unlike Non-Institutional Investors who are required to bid at a specific price within the band, are permitted to bid at the cut-off price. When a retail investor selects cut-off, they agree in advance to subscribe at whatever price the issuer and the book running lead managers determine as the issue price at the conclusion of the book-building process. This eliminates the risk that a price-specific bid falls outside the final price band and is therefore rejected.

In practice, the overwhelming majority of retail applicants in Indian IPOs select cut-off pricing because the alternative, bidding at a specific price within the price band, requires the investor to predict where the final price will land, and any bid below the final issue price will be treated as a rejected bid with no allotment and an immediate unblock of the application amount.

Eligibility and exclusions

Any natural person who is a resident Indian (as defined under FEMA) and holds a valid PAN and a demat account with a depository participant registered with either NSDL or CDSL may apply as an RII, subject to the ₹2,00,000 bid cap. The person must also have an ASBA-enabled bank account with an SCSB or a UPI-linked bank account through which the mandate can be authorised.

Entities, including companies, partnership firms, Hindu Undivided Families (HUFs), trusts, and any other non-natural-person legal entity, are not eligible for the RII category, even if their application value is within the ₹2,00,000 ceiling. HUFs applying in the name of the karta are treated as individuals for this purpose and qualify as RIIs if the bid value is within the ceiling. SEBI has periodically clarified this in FAQ circulars.

Employees of the issuer company who apply under the employee reservation portion of an IPO are treated separately from the RII category and subject to the terms of the employee reservation, which typically allows a discount of up to 10 per cent on the issue price and imposes a lock-in period on allotted shares.

Historical evolution of the retail threshold

The ₹2,00,000 ceiling has not always been at its current level. The SEBI (Disclosure and Investor Protection) Guidelines, 2000, the predecessor regulatory framework, defined retail investors as those applying for up to ₹1,00,000 in a fixed-price issue or up to 1,000 shares in a book-built issue, with a separate definition for larger individual investors. The introduction of the DIP Guidelines Amendment of 2004, which aligned the definition more closely to bid value, and the subsequent revision under the SEBI (ICDR) Regulations, 2009 raised the threshold to ₹2,00,000, approximately reflecting the purchasing-power changes between 2000 and 2009.

The current SEBI ICDR Regulations, 2018 retained the ₹2,00,000 figure when they replaced the 2009 regulations. The threshold has therefore been stable at ₹2,00,000 since approximately 2009, a period of over fifteen years during which the Sensex increased roughly six-fold and average ticket sizes in mainboard IPOs expanded substantially. As of mid-2026, there is periodic commentary in the financial press about whether SEBI should revise the ceiling upward to ₹5,00,000 to reflect inflation, but no formal SEBI consultation paper on the subject has been published.

Common issues and edge cases

Multiple applications from one PAN. The registrar’s reconciliation system, operated in conjunction with the depositories NSDL and CDSL , flags applications where the same PAN appears more than once in the same investor category. All applications from a duplicated PAN in the same category are rejected. Investors who hold joint demat accounts should note that the PAN used for demat and the PAN used for the IPO application must match; the first holder’s PAN is treated as the applicant PAN.

Application amount rounding. The UPI mandate is raised for the exact application amount calculated at the cut-off price option. If the issue price is set below the upper end of the price band, the mandate amount is unblocked and re-blocked for the lower amount in some systems; in others, the excess is unblocked only on the allotment date. The actual debit to the investor’s account is always the lower, final allotment-value amount.

Revising and withdrawing bids. An RII can revise or withdraw their bid at any time before the close of the subscription period. Bid revision is done through the same broker or bank interface used for the original submission. Once the subscription period closes, bids are locked; withdrawal after closure is not permitted except in limited circumstances specified by the exchange, such as a price band revision by the issuer.

Technical rejection reasons. Common technical rejection reasons in the RII category include: PAN not updated in the depository records; demat account not active; UPI mandate not approved within the stipulated time (typically 5 business days from the mandate request, though in practice investors are expected to approve within 24 hours to avoid technical errors); SCSB not on the list of approved SCSBs for the particular issue; and application amount exceeding the ₹2,00,000 ceiling after adjusting for lot size.

Grey market premium and retail behaviour. The informal grey market for IPO shares provides a proxy for expected listing price and influences retail subscription patterns. In issues where the grey market premium (GMP) is high relative to the issue price, retail oversubscription ratios can reach several hundred times the available allocation. In such issues, the lottery probability per application falls to very low levels. Retail investors in those situations often reason that since allotment probability is roughly equal across all valid applications regardless of bid size, applying for the minimum one lot is financially equivalent to applying for the maximum permissible lots.

Retail investors in rights issues and FPOs

The RII category exists not only in IPOs but also in rights issues and Follow-on Public Offers (FPOs). In a rights issue, however, the allocation structure is fundamentally different, entitlements are distributed to existing shareholders in proportion to their holdings, and the ₹2,00,000 ceiling on the RII definition is less directly operative because existing shareholders apply for their entitlement regardless of bid value. In FPOs on the mainboard, the same 35 per cent RII floor applies as in IPOs, and the UPI ASBA mechanics are identical.
