ASBA stands for Application Supported by Blocked Amount, is a secure, efficient way introduced by SEBI for applying to IPOs and follow-on public offerings.
This article explains what ASBA is, its advantages, and how you can apply using this method.

What is ASBA?
ASBA is an IPO application process where the application money remains in your bank account but is blocked (or put on hold) for the IPO subscription amount until shares allotted or rejected.
If allotted, the respective amount debited, if not allotted fully, the blocked amount released back to the account instantly.
This process minimizes inconvenience by avoiding upfront payments and delay in IPO refund after IPO allotment.
How does ASBA Work?
- You submit the IPO application through a Self Certified Syndicate Bank (SCSB) or using net banking with ASBA facility.
- The bank blocks the required application amount in your account but does not debit immediately.
- On IPO allotment, the allotted amount debited, and the balance released instantly.
- You continue to earn interest on the blocked amount while funds held.
