ASBA
ASBA — Application Supported by Blocked Amount — is the standard process for IPO applications in India. Instead of paying upfront, your bank blocks the application amount in your savings account; if shares are allotted, the blocked amount is debited; if not, it is released back to you. ASBA simplified IPO investing and is fully integrated with UPI for retail investors.
Key takeaways:
- ASBA blocks funds in your bank account until IPO allotment.
- Mandatory for retail and HNI applications since SEBI’s 2008 framework.
- UPI-based ASBA is the most common retail route today.
- You earn savings-account interest on the blocked amount until debit.
- Eliminates the need to send cheques or wait for refunds.
How ASBA works
- You apply for an IPO through your broker.
- Choose UPI as the payment mode.
- Receive a UPI mandate request on your phone.
- Approve the mandate — your bank blocks the application amount.
- If shares are allotted, the blocked amount is debited; if not, the block is released.
Why ASBA exists
Before ASBA, IPO applicants had to send cheques or demand drafts and wait days for refunds if they did not receive allotment. The blocked-amount mechanism removed that friction — no more lost interest on application money, no refund delays, and significantly reduced operational risk.
UPI vs Bank-ASBA
| UPI-ASBA | Bank-ASBA | |
|---|---|---|
| Application limit | ₹5 lakh (retail) | Any amount |
| Speed | Instant | Through bank branch / netbanking |
| Best for | Retail individuals | HNIs and very large applications |
Common ASBA-related issues
- UPI mandate not received — check the app notification settings.
- Mandate approved twice — only one block is valid; others are rejected.
- Insufficient funds at the time of allotment — your application can be rejected.
- Multiple PAN-based applications — flagged and may be invalidated.
Practical tips
- Approve the UPI mandate within the window provided (typically a few days).
- Keep sufficient balance until allotment day to avoid rejection.
- Apply through one PAN account only — multiple applications from the same PAN are not allowed.
- Watch the application status; reject reasons are visible in your broker portal.
Beyond IPOs
ASBA is also used for Follow-on Public Offers (FPOs), rights issues, and certain bond issues. The underlying mechanism — block now, debit on allotment — is the same. SEBI continues to enhance ASBA processes, with recent moves to allow ASBA-based trading and faster settlement.
