ASBA (Applications Supported by Blocked Amount) is a SEBI‑mandated process that blocks the application money in your bank account until the IPO allotment is finalised. If shares are allotted, the blocked amount is debited; otherwise, it is released. This method eliminates the need to transfer funds upfront and reduces refund delays.
What is ASBA and why is it used for IPO applications?
ASBA stands for Applications Supported by Blocked Amount. Under this mechanism, the money required for an IPO application remains in your bank account and is only blocked, not transferred to the issuer or the registrar. The block is lifted if the application is unsuccessful, or the amount is debited if shares are allotted. This protects investors from having to refund money and ensures that funds earn interest until the allotment decision.
Who can apply for an IPO through ASBA?
Any retail investor who holds a savings or current account with a bank that offers the ASBA facility can use it. You also need a demat account where the allotted shares will be credited. Non‑institutional investors (NIIs) and qualified institutional buyers (QIBs) use different payment routes, but the retail category is eligible for ASBA.
What details and documents are required to apply via ASBA?
- A valid PAN number.
- A demat account number (DP ID and Client ID) linked to your PAN.
- The bank account number where you want the amount blocked (must be with a bank that supports ASBA).
- The IPO application form (either physical or online) containing the investor’s name, PAN, demat details, bid quantity, and price.
- For online applications through brokers, your login credentials and consent to block the amount.
How to apply for an IPO using ASBA – step‑by‑step
- Log in to your broker’s platform or net‑banking portal that offers the ASBA option for the ongoing IPO.
- Select the IPO you wish to apply for and enter the number of shares (or lot size) and the price you are willing to pay (cut‑off or specific price within the band).
- Enter your demat account details (DP ID and Client ID) and confirm that the PAN on file matches your bank account.
- Choose the bank account from which the amount will be blocked. The system will show the tentative block amount (number of shares × price).
- Authorize the block – this is usually done via an OTP sent to your registered mobile or through your internet banking transaction password.
- Once authorized, the bank marks the amount as “liened” or blocked. You will receive a confirmation SMS/email with the application number.
- Keep the application number safe; you can use it to check the status on the registrar’s website or the exchange portal.
If you prefer a physical route, you can fill out a paper ASBA form, attach a cancelled cheque or bank statement as proof of account, and submit it to a self‑certified syndicate bank (SCSB) or your broker’s office.
What happens after you submit an ASBA application?
After the bidding period ends, the registrar consolidates all applications. If your bid is successful and shares are allotted, the blocked amount is debited from your account and the shares are credited to your demat account. If the IPO is oversubscribed and you do not receive an allotment, the bank releases the lien, and the full amount becomes available again in your account. In case of a partial allotment, only the proportionate amount is debited and the rest is released. The entire process typically takes a few working days after the allotment date.
Frequently Asked Questions
Question : Is there any charge for using the ASBA facility?
Answer : Most banks do not charge a fee for blocking the amount under ASBA. However, your broker may levy a nominal transaction charge for placing the bid on your behalf, which is disclosed upfront.
Question : Can I modify or withdraw my ASBA bid after submission?
Answer : Yes, you can modify the bid quantity or price, or withdraw the application entirely, as long as you do so before the bid closure date. Changes are made through the same platform where you placed the original bid, and the blocked amount is adjusted accordingly.
Question : What happens if my bank account does not have sufficient balance when the block is attempted?
Answer : The block will fail, and the application will be considered invalid. You must ensure that the required funds are available in the account at the time of authorising the block.
Question : Do I need to maintain the blocked amount until the allotment date?
Answer : The amount remains blocked only until the allotment decision is made. Once the registrar finalises the basis of allotment, the bank either debits the allotted amount or releases the lien. You do not need to keep the funds blocked beyond that point.
Question : Can I apply for multiple IPOs simultaneously using ASBA?
Answer : Yes, you can submit separate ASBA applications for different IPOs, each blocking the respective amount in your bank account. Ensure that your account has sufficient balance to cover all simultaneous blocks.
Question : Is ASBA available for all types of investors?
Answer : ASBA is primarily designed for retail individual investors. Non‑institutional investors and qualified institutional buyers use other payment mechanisms, such as RTGS/NEFT or direct payment to the escrow account.
