UPI for IPOs

1. The ASBA Revolution

ASBA (Applications Supported by Blocked Amount) transformed IPO applications in India. Instead of transferring money upfront and waiting for refunds, ASBA blocks the application amount in your bank account. You earn interest until allotment, and only the allotted amount is debited.

2. How UPI-ASBA Works

The UPI-based ASBA process for IPOs:

1. Apply: Submit IPO application through your broker's app or bank's net banking
2. UPI Mandate: You receive a UPI mandate request on your phone (via Google Pay, PhonePe, etc.)
3. Approve: You approve the mandate, blocking the application amount
4. Allotment: If shares are allotted, the blocked amount is debited
5. Refund: If not allotted (or partially allotted), the blocked amount is released

3. Why UPI-ASBA Is Better

Compared to the old system:

Old System	UPI-ASBA
Money debited immediately	Money blocked, not debited
No interest during waiting period	You earn interest on blocked amount
Refund took 7-15 days	Release within 1-2 days of allotment
Physical forms required	Fully digital
Multiple bank visits	One-click UPI approval

4. UPI Mandate Details

Key things to know about UPI mandates:

• Validity: The mandate is valid until the IPO allotment date
• Blocking: The amount is blocked but remains in your account
• Partial blocking: If applying for ₹1 lakh and getting ₹20,000 allotment, only ₹20,000 is debited
• Revocation: You can revoke the mandate before the issue closes (but you'll lose your application)

5. Common IPO Application Mistakes

1. Multiple applications with same PAN: All applications get rejected
2. Not approving UPI mandate: If you don't approve within the timeframe, application is rejected
3. Insufficient funds: The blocked amount must cover your full application
4. Wrong category: Retail, HNI, and employee categories have different rules and allotment ratios
5. Last-minute application: UPI mandates may fail if applied too close to the deadline

6. IPO Allotment Mechanics

For retail investors:

• If the issue is undersubscribed in the retail category: Everyone gets full allotment
• If the issue is oversubscribed: SEBI mandates a minimum allotment lot to maximum applicants
• Pro-rata: For HNI category, allotment is proportional to application size

The "lot size" determines the minimum and multiples you can apply for. A lot size of 50 means you must apply for 50 shares or multiples thereof.

7. Grey Market Premium (GMP)

The grey market is an unofficial market where IPO shares trade before listing. The Grey Market Premium (GMP) indicates expected listing gains:

• High GMP → Strong demand, likely listing pop
• Low/negative GMP → Weak demand, possible listing discount

However, GMP is unofficial, unregulated, and often manipulated. Don't base investment decisions solely on GMP.
