In the past, the IPO process was lengthy and complicated. Investors had to visit their broker’s office to collect and fill out IPO application forms, then submit them physically, which was time-consuming and cumbersome. This involved multiple steps and paperwork, leading to a drawn-out process. However, the introduction of the Application Supported by Blocked Amount (ASBA) system has simplified this experience. ASBA allows investors to apply for IPOs online, directly through their bank accounts, which blocks the application amount without actually debiting it until the shares are allocated. This streamlines the process, making it quicker and more convenient.
To start investing in an IPO, you need to open demat account or trading account.
After setting up your account, you can apply for IPOs online using one of two methods: the ASBA (Application Supported by Blocked Amount) facility, which is available through most banks, or by using your UPI ID.
ASBA simplifies the process by blocking the application amount without debiting it until shares are allocated, while UPI allows a straightforward application process through your bank account. Both methods streamline the IPO investment experience.
ASBA, or Application Supported by Blocked Amount, is a system developed by SEBI to simplify the IPO application process. It allows investors to block the amount required for an IPO in their bank accounts rather than transferring the money upfront. This means the blocked amount remains in the investor’s account and continues to earn interest until the shares are allotted.
If your application is selected for allotment, the money is debited from your account only at that time. If you are not allotted shares or decide to withdraw your application, the blocked amount is released back into your account. This system enhances transparency and ensures that funds are available only when necessary.
Since 2016, SEBI has mandated the use of the ASBA form for all IPO applications. For non-retail investors, applying through ASBA is compulsory, ensuring that the funds are managed efficiently and securely throughout the IPO process.
You can apply for an IPO using ASBA both online and offline. We will discuss both the medium:
Through a Broker
To apply for an IPO online ASBA, follow the steps discussed below:
To apply for an IPO conveniently through ASBA, investors must meet the following eligibility criteria:
Given below are some of the major advantages of applying through ASBA:
Investors with a valid PAN card, a Demat account, and a bank account with a Self Certified Syndicate Bank (SCSB) can apply through ASBA
Investing in an IPO offers the potential for substantial returns if the company performs well. It allows early access to shares of a company, often at a lower price, and can be a chance to participate in a company’s growth journey.
To apply as a High Net-Worth Individual (HNI), you need to place your bid through an SCSB using the ASBA facility
A Self Certified Syndicate Bank (SCSB) is a bank certified by SEBI to process ASBA applications. It blocks the IPO application amount in the investor’s account and only debits the funds if the investor is allotted shares.
No, ASBA applications must be submitted directly to an SCSB, not to a broker.
When applying through ASBA, the required amount is blocked in your bank account. Funds are only debited if you are allotted shares. If not allotted or if you withdraw your application, the funds remain blocked and are released back to your account.
