What is ASBA? Complete guide for Investors in 2026
Before 2008, applying for an IPO in India was a messy business. You had to send a physical cheque for the full amount, your money would leave your bank account for months, and if you didn't get any shares, you had to wait even longer for a refund. Sometimes, those refund cheques got lost in the mail!
To solve this, SEBI (the stock market regulator) introduced ASBA, which stands for Application Supported by Blocked Amount.
In simple terms, ASBA is like a reservation for your money. When you apply for an IPO, your bank doesn't send the money to the company. Instead, it just puts a lock on that amount in your own savings account. The money stays with you, you continue to earn interest on it, and it only leaves your account if you are actually lucky enough to get shares. In 2026, ASBA is not just an option, it is mandatory for every investor in the Indian market.
How does ASBA work? (The Simple Cycle)
The beauty of ASBA is that it happens entirely between you, your bank, and the stock exchange.
-
Instruction: When you fill out your IPO application (via UPI or Net Banking), you give your bank a Mandate to block a specific amount (e.g., ₹15,000).
-
The Block: Your bank marks this amount as Reserved. You will see it in your balance, but you cannot spend it or withdraw it.
-
Interest: Because the money is still technically in your account, your bank keeps paying you your regular Savings Account Interest on that blocked amount.
-
The Decision:
- If you get shares: The bank unlocks the money and sends it to the company.
- If you don't get shares: The bank simply removes the lock. The money is instantly available for you to use again. No waiting for refunds!
