1. What Is T+0 Settlement?
T+0 (same-day) settlement means shares and money exchange hands on the same day the trade occurs. SEBI began piloting T+0 in 2024 for a limited set of stocks and brokers, with plans for broader rollout.
2. How T+0 Differs from T+1
| Aspect | T+1 | T+0 |
|---|---|---|
| Settlement time | Next business day | Same day |
| Fund availability | T+1 for sellers | Same day for sellers |
| Share availability | T+1 for buyers | Same day for buyers |
| Broker funding need | Overnight bridge | Minimal or none |
| Technology requirement | Standard | Real-time systems |
| Risk level | Moderate | Lower counterparty risk |
3. The T+0 Pilot Structure
SEBI's T+0 pilot operates in two sessions:
- Session 1 (T+0): Normal market hours (9:15 AM – 1:30 PM for T+0 trades)
- Session 2 (T+1): Remaining hours for T+1 settlement trades
Brokers must have separate T+0 and T+1 pools of funds and securities. The clearing house processes T+0 settlements during market hours.
4. Why T+0 Matters
T+0 settlement transforms market dynamics:
- Capital efficiency: Brokers need less working capital since funds turnover same-day
- Reduced risk: Counterparty exposure lasts hours instead of overnight
- Global alignment: US markets are moving toward T+1; India leapfrogs to T+0
- Retail benefit: You can sell shares and use proceeds to buy new shares the same day
5. Challenges of T+0
Implementation isn't trivial:
- Technology: Requires real-time clearing systems, not batch processing
- Banking integration: Fund transfers must happen instantly, not via NEFT
- Operational complexity: Brokers need dual settlement tracks
- Cost: Significant investment in infrastructure
6. Impact on Trading Strategies
T+0 changes how strategies work:
- Arbitrage: Faster settlement reduces funding arbitrage opportunities
- Day trading: Proceeds available same day for reinvestment
- BTST: Buy Today Sell Tomorrow becomes less risky since shares credit same day
- Broker margins: May compress as funding needs decrease
7. Timeline for Full Rollout
SEBI's phased approach:
- Phase 1 (2024): Pilot with top 25 stocks, limited brokers
- Phase 2 (2025): Expand to top 500 stocks
- Phase 3 (2026+): Full market T+0
💡 Key Takeaway
T+0 is the future of Indian settlement. It eliminates overnight risk, improves capital efficiency, and aligns India with the most advanced market infrastructure globally. But full rollout requires massive technology upgrades across brokers, banks, and clearing houses.
