Initial Public Offering Process in India: IPO Steps (CAIIB ABFM 2026)

The initial public offering process in India is one of the most heavily tested capital-market topics in CAIIB ABFM, and it is also one that trips up candidates who confuse the mechanics of book building with the mechanics of a fixed-price issue. As a bank officer, you will encounter IPO-linked products — ASBA, UPI mandates, anchor allotments — across retail, wealth and treasury desks, so the exam expects working knowledge, not just definitions. This article walks through price discovery, price band construction, anchor investor rules and the post-closure listing timeline exactly as SEBI has structured them under the SEBI (ICDR) Regulations, 2018.

Before you go further, revise how a company's leadership actually organises this exercise. An IPO is, at its core, a project — it needs planning of the offer structure, organising of merchant bankers, registrars and legal counsel into a syndicate, and continuous controlling of the timeline against SEBI's regulatory clock. Keep that management lens in mind as you read the capital-market detail below.

📊 What Is Book Building and How Price Discovery Works

Book building is the SEBI-permitted mechanism by which the issue price of shares is discovered through actual investor demand rather than being fixed upfront by the issuer. Under a book-built issue, the company and its lead merchant bankers do not announce one price — they announce a price band, and investors bid within that band, indicating both the quantity of shares they want and the price they are willing to pay.

The lead manager and syndicate members collect these bids over the bidding period through the electronic bidding platforms of the stock exchanges. Every bid is logged with a bid-cum-application form, and the demand at each price point within the band is aggregated into a live "order book" — hence the name book building. At the end of the bidding period, the issuer and lead manager determine the cut-off price, which is the price at which the entire issue size can be subscribed given the demand pattern observed.

This is distinct from the older fixed-price method, where the issuer names one price in the prospectus and investors simply apply at that price with no bidding. Fixed-price issues are now rare for mainboard IPOs; almost all sizeable Indian IPOs since the early 2010s use book building because it lets the market, not the merchant banker's judgment alone, set the price. Retail investors bidding in a book-built issue can apply "at cut-off price", meaning they agree to pay whatever final price is discovered, which removes the risk of under-bidding and being rejected on price grounds.

💡 Exam Tip: Remember the sequence — draft red herring prospectus, price band announcement, bidding period (minimum three working days, extendable), cut-off price determination, allotment, refund/unblocking, then listing.

💰 Price Band, Floor Price and Cap Price Explained

The price band consists of two numbers: the floor price, which is the minimum price at which shares can be allotted, and the cap price, which is the maximum. SEBI's ICDR framework requires that the cap price not be disproportionately higher than the floor price — the band has to be reasonably tight so that price discovery is meaningful rather than a token exercise, and issuers typically keep the spread modest as a matter of regulatory practice and market convention.

The price band is disclosed at least two working days before the bid opening date, giving investors and analysts time to study the red herring prospectus, the company's financials and peer valuations before committing funds. Once the band is announced, it cannot be tinkered with arbitrarily; any revision follows a defined process, and the bidding period may be extended by a minimum of three additional working days if the band is revised during the offer.

Retail individual investors bidding at cut-off price effectively bid at the cap price for margin-blocking purposes but are refunded or allotted at whatever final cut-off price is discovered — which can be at, below, or at the cap depending on demand. This protects small investors from having to guess the exact clearing price. Institutional and non-institutional bidders, in contrast, generally quote a specific price within the band rather than opting for cut-off.

⚠️ Common Mistake: Do not confuse the price band with the final issue price. The band is a range disclosed before bidding opens; the issue price (or cut-off price) is a single number fixed only after the book closes.

🎯 Anchor Investors: Role, Allocation and Lock-in

Anchor investors are qualified institutional buyers who are allotted shares a day ahead of the public issue opening, at a price decided by the issuer in consultation with the lead managers. The anchor mechanism exists to build confidence in the offer — when large, credible institutions commit capital upfront, it signals demand quality to the retail and non-institutional investors who bid later.

Under SEBI ICDR norms, the anchor investor portion is carved out of the QIB (qualified institutional buyer) category and is capped at a defined proportion of the QIB portion, with the anchor allocation itself further capped per investor to ensure a reasonably diversified anchor book rather than concentration in one or two entities. Anchor bidding happens strictly one day before the issue opens to the public, and the price paid by anchors cannot be lower than the price at which allocation is made to other QIBs in the main book.

A defining feature tested repeatedly in CAIIB ABFM is the lock-in on anchor shares. SEBI requires a portion of anchor allotment to be locked in for a shorter initial period and the remaining portion for a longer secondary period after listing, specifically to prevent anchors from dumping shares on listing day and distorting the stock's early price discovery. This lock-in structure is one of the clearest differences between an anchor investor and an ordinary QIB bidder, who faces no such restriction once shares are allotted and listed.

Good governance around this stage also depends on how the issuer's own management team executes its responsibilities — the same directing and staffing functions you studied in the general management chapters apply directly to how a company builds the internal IPO team that liaises with anchors and the lead bank.

📈 Listing Process and Timeline After IPO Closure

Once bidding closes, the registrar to the issue finalises the basis of allotment in consultation with the designated stock exchange, applying the SEBI-prescribed proportionate allotment methodology for each investor category. Successful applicants are allotted shares in demat form, unsuccessful and partially successful applicants have their ASBA-blocked or UPI-blocked funds released, and the company then applies for listing and trading approval from the exchanges where it intends to list — typically the BSE and the NSE.

SEBI has progressively compressed the post-issue-closure timeline over the last decade to reduce the time investor money stays blocked. The regulator's reforms brought listing down from the older T+6 working-day norm to T+3 from the date the issue closes, meaning trading in the newly listed shares can begin within three working days of bid closure. This is possible because allotment, demat credit and fund unblocking now happen almost entirely through automated, exchange-linked systems rather than manual reconciliation.

On listing day, the stock exchange conducts a special pre-open call auction session to discover the opening trade price, after which normal continuous trading begins. Candidates should also remember that a company can withdraw or extend an issue in defined circumstances, and that the green shoe option (over-allotment option) permits post-listing price stabilisation for a limited window, which is a distinct mechanism from the anchor lock-in discussed above.

📌 Remember: The compressed T+3 listing timeline is a direct SEBI ICDR/circular-driven reform and is a favourite one-mark question — do not confuse it with the older T+6 cycle that examiners sometimes cite as a distractor option.

🎓 Conclusion: Getting IPO Process Questions Right in CAIIB ABFM

The initial public offering process in India rewards candidates who can sequence the stages correctly — price band disclosure, anchor allotment, book building, cut-off pricing, allotment and the compressed listing timeline — rather than those who memorise isolated facts. Anchor it in the same management-cycle logic you already know: planning, organising, directing and controlling apply as much to running a public issue as they do to running a bank branch.

For a related regulatory angle on how banking companies themselves are governed once capital is raised, revisit RBI's control over management of banking companies from the CAIIB BRBL syllabus.
