14 May 2025 · Sachin Gadekar
Looking for stability in uncertain markets? Learn how to use Treasury Bills (T-Bills) and Government Securities (G-Secs) to build a resilient investment core.

🛡️ What Are T-Bills and G-Secs?
When it comes to building a robust investment portfolio, not all capital should be exposed to high risk. That’s where risk-free instruments like T-Bills and G-Secs come in. While equity and private assets offer the thrill of growth, T-Bills and G-Secs offer something far more important for long-term planning: stability and predictability.
In this article, we explore how you can strategically use these government-backed securities to anchor your portfolio while keeping liquidity, safety, and tax efficiency in mind.
Treasury Bills (T-Bills) are short-term debt instruments issued by the Government of India with maturities of 91, 182, or 364 days. They are sold at a discount and redeemed at face value—meaning you earn the difference.
Government Securities (G-Secs) are medium to long-term bonds (up to 40 years) issued by the government. They offer regular interest payouts (called coupons) and are considered virtually risk-free due to sovereign backing.
💡 Why They Matter in a Modern Portfolio
These instruments serve as the core of capital preservation strategies. When equity markets fluctuate, these investments remain stable or even gain value as interest rates drop.
Benefits of T-Bills and G-Secs include:
Guaranteed principal and interest (backed by the government)
Predictable returns
Liquidity (tradable on platforms like RBI Retail Direct and NSE/BSE)
Tax efficiency in certain formats
🧱 Building a Risk-Free Core with T-Bills and G-Secs
1. Start with Your Time Horizon
T-Bills are ideal for goals within 1 year.
G-Secs are perfect for longer-term stability in goals 5–15 years away.
2. Define the Core Allocation
A common strategy is to keep 15–30% of your portfolio in low-risk assets, depending on your age, risk appetite, and market outlook.
🎯 Example: A 30-year-old investor may allocate 20% to G-Secs, while a retiree might go up to 60%.
3. Use Laddering for Stability + Liquidity
You can ladder your G-Secs across different maturities (e.g. 5, 10, 20 years) to ensure regular liquidity and reinvestment opportunities.
4. Consider T-Bills for Emergency Funds
T-Bills can be a smarter alternative to savings accounts or FDs, offering better returns with nearly zero risk.
📊 T-Bills vs G-Secs: Key Differences
Instrument | Tenure | Return Type | Best For |
---|---|---|---|
T-Bills | 91 to 364 days | Discount-based (no interest) | Short-term cash management |
G-Secs | 1 to 40 years | Coupon (interest paid semi-annually) | Long-term wealth preservation |
🚀 When Should You Invest in T-Bills or G-Secs?
Scenario | Recommendation |
---|---|
Parking funds for 3–12 months | T-Bills |
Creating a stable retirement base | G-Secs with long durations |
Interest rate drop expected | G-Secs (benefit from price gain) |
Diversifying equity risk | Both (as fixed-income core) |
🔐 Use Case: Blending Ultra with G-Secs
