Understanding the Yield Curve: A Complete Guide for Indian Bond Investors
If you've ever wondered whether to buy a 1-year bond or a 10-year bond, or why sometimes long-term bonds pay less than short-term bonds (yes, that happens!), you need to understand the yield curve.
The yield curve is one of the most powerful tools in finance - it can:
- Tell you what the market expects about future interest rates
- Predict economic recessions (with surprising accuracy)
- Help you decide which bond maturity to invest in
- Indicate the best time to lock in long-term rates
Despite its importance, most retail investors in India don't understand it or use it. This guide changes that.
We'll break down the yield curve from basics to practical investment strategies - all in the Indian context with current examples.
What is a Yield Curve?
At its core, a yield curve is surprisingly simple:
A yield curve is a line graph showing the relationship between bond yields and their time to maturity.
That's it. It plots:
- X-axis: Time to maturity (3 months, 1 year, 5 years, 10 years, etc.)
- Y-axis: Yield (interest rate you earn)
Example: Imagine today's government bond yields are:
- 3-month T-Bill: 6.5%
- 1-year T-Bill: 6.8%
- 3-year G-Sec: 7.0%
- 5-year G-Sec: 7.2%
- 10-year G-Sec: 7.3%
- 30-year G-Sec: 7.4%
Plot these points and connect them - you get a yield curve.
Why is This Important?
The shape of this curve tells you a lot:
- What investors expect about future interest rates
- How the economy is likely to perform
- Which maturity bonds offer better value
- Whether it's time to lock in long-term rates or stay short-term
The Three Main Types of Yield Curves
1. Normal (Upward Sloping) Yield Curve
Shape: Rises from left to right (longer maturity = higher yield)
What it looks like:
Yield
8% | •
| •
7% | •
| •
6% | •
| •
|________________________________
3M 1Y 3Y 5Y 10Y 30Y Maturity
What it means:
- Longer-term bonds pay higher interest rates
- Investors demand extra return for tying up money longer
- Economy is expected to grow normally
- Inflation is expected to be moderate
Current Indian Scenario (as of Dec 2024):
- 91-day T-Bill: ~6.8%
- 1-year G-Sec: ~7.0%
- 5-year G-Sec: ~7.2%
- 10-year G-Sec: ~7.3%
This is a mildly upward sloping curve - normal and healthy.
What this means for investors:
- Fair compensation for longer-term investment
- No major economic concerns
- Can consider long-term bonds for better returns
2. Flat Yield Curve
Shape: Almost horizontal (similar yields across maturities)
What it looks like:
Yield
7.2%| • • • • • •
|
7.0%|
|
|________________________________
3M 1Y 3Y 5Y 10Y 30Y Maturity
What it means:
- Short-term and long-term bonds offer similar yields
- Uncertainty about economic direction
- Transition period (could go to normal or inverted)
- Market can't decide if rates will rise or fall
Example (hypothetical):
- 1-year bond: 7.1%
- 5-year bond: 7.2%
- 10-year bond: 7.15%
What this means for investors:
- Little incentive to lock money long-term
- Consider staying in short-term bonds for flexibility
- Wait for clarity before making long-term commitments
3. Inverted (Downward Sloping) Yield Curve
Shape: Falls from left to right (longer maturity = LOWER yield)
What it looks like:
Yield
8% | •
| •
7% | •
| •
6% | •
| •
|________________________________
3M 1Y 3Y 5Y 10Y 30Y Maturity
What it means:
- Short-term bonds pay MORE than long-term bonds (counterintuitive!)
- Investors expect interest rates to fall in the future
- Often predicts economic recession within 12-18 months
- Market expects central bank to cut rates
Example (hypothetical scenario):
- 1-year T-Bill: 7.5%
- 5-year G-Sec: 7.0%
- 10-year G-Sec: 6.8%
Historical fact: Inverted yield curve has predicted 7 out of the last 8 US recessions.
What this means for investors:
- Lock in long-term rates NOW before they fall further
- Economic slowdown likely ahead
- Long-term bonds may give capital gains if rates fall
Why Does the Yield Curve Shape Change?
Understanding the "why" helps you predict and react better.
Factor 1: Interest Rate Expectations
If markets expect RBI to raise rates in the future:
- Short-term yields rise faster than long-term
- Curve may flatten or invert
If markets expect RBI to cut rates:
- Long-term yields fall more than short-term
- Curve becomes steeper (more upward sloping)
Recent Indian Example (2022-2023):
- RBI raised repo rate from 4% to 6.5% (to fight inflation)
- Short-term yields jumped quickly
- Yield curve flattened significantly
- 10-year yield rose from 6.5% to 7.4%
Factor 2: Inflation Expectations
Higher expected inflation → Investors demand higher yields on long-term bonds
- Curve steepens (long-term yields rise more)
Lower expected inflation → Lower long-term yields
- Curve may flatten
Why: Inflation erodes the real value of future interest payments. Long-term bonds are more affected.
Factor 3: Economic Growth Expectations
Strong growth expected:
- Higher demand for credit
- Upward pressure on yields
- Steeper curve
Weak growth/recession expected:
- Lower credit demand
- Central bank likely to cut rates
- Curve may flatten or invert
Factor 4: RBI Policy Actions
When RBI raises repo rate:
- Short-term yields rise immediately
- Long-term yields rise but less (already priced in)
- Curve flattens
When RBI signals rate cuts:
- Long-term yields fall (anticipation)
- Short-term yields stay higher (until actual cut)
- Curve steepens
Current Scenario (Dec 2024):
- RBI has paused rate hikes
- Inflation moderating (around 5%)
- Yields have stabilized
- Curve is mildly upward sloping (normal)
The Indian Yield Curve: Current State
Let's look at the actual current Indian government bond yields (as of December 2024):
| Maturity | Yield (Approx) | Type |
|---|---|---|
| 91-day T-Bill | 6.75% | Ultra Short |
| 182-day T-Bill | 6.80% | Short |
| 364-day T-Bill | 6.85% | Short |
| 2-year G-Sec | 6.95% | Short-Medium |
| 5-year G-Sec | 7.15% | Medium |
| 10-year G-Sec | 7.30% | Long |
| 30-year G-Sec | 7.40% | Very Long |
Shape: Upward sloping (normal curve)
Key Observations:
- Positive slope: Extra ~0.65% for going from 3-month to 30-year
- Steepest rise: Between 1-year and 5-year (6.85% to 7.15%)
- Flatter at long end: 10-year to 30-year only adds 0.10%
What this tells us:
- Market expects stable rates in near term
- Modest inflation expectations (5-5.5%)
- Moderate growth outlook
- No recession fears (curve not inverted)
- RBI likely to hold rates in next 6 months
Investment implication:
- Reasonable to invest in 5-10 year bonds for extra yield
- No urgency to lock in very long term (30-year) given small extra yield
- Short-term bonds (1-2 year) acceptable if you want flexibility
How the Yield Curve Predicted Past Economic Events
Global Financial Crisis (2008)
2006-2007: US yield curve inverted
- 3-month T-Bill: 5.25%
- 10-year bond: 4.70%
Result: Recession hit in 2008 (as predicted)
COVID-19 Pandemic (2020)
Early 2020: Yield curves globally flattened dramatically
- Uncertainty about economic impact
- Central banks slashed rates
India:
- RBI cut repo rate from 5.15% to 4%
- 10-year yield fell from 6.5% to 5.8%
- Curve steepened as economy reopened
Post-COVID Recovery (2021-2022)
2021-2022: Inflation surge
- Global and Indian yields rose sharply
- Curve flattened (short-term yields rose faster)
- Predicted: Growth with inflation (stagflation risk)
Result: RBI hiked rates aggressively (2022-2023)
Current Cycle (2023-2024)
2023: Curve normalized
- Inflation moderating
- Growth stable
- Normal upward slope returning
Prediction: Stable rates, moderate growth - so far accurate!
How to Use the Yield Curve for Investment Decisions
Now for the practical part - how YOU can use this information.
Strategy 1: Riding the Yield Curve
When: Normal upward sloping curve
How it works:
- Buy a longer-maturity bond (say 10-year)
- As time passes, it becomes shorter-maturity (9-year, 8-year...)
- If yield curve stays same shape, your bond's yield falls (price rises)
- Sell before maturity for capital gain
Example:
Today:
- 10-year G-Sec yields: 7.3%
- You buy ₹10,00,000 worth
After 2 years (now it's an 8-year bond):
- 8-year G-Sec yields: 7.2% (curve unchanged)
- Your bond yields 7.3% (higher than current 8-year)
- Bond price rises to ~₹10,08,000
- You can sell for ₹8,000 profit + 2 years of interest
Risk: If yield curve shifts upward, you could have losses
Strategy 2: Barbelling (Short + Long, Skip Medium)
When: Uncertain about rate direction
Strategy:
- 50% in very short-term bonds (3-12 months)
- 50% in long-term bonds (10+ years)
- Avoid medium-term (3-5 years)
Why:
- Short-term: Flexibility to reinvest if rates rise
- Long-term: Lock in current rates if rates fall
- Skip medium: Not enough yield vs long, not enough flexibility vs short
Example Portfolio (₹10,00,000):
- ₹5L in 91-day T-Bills (rollover every 3 months): 6.75%
- ₹5L in 15-year G-Sec: 7.35%
- Average: ~7.05%
Vs traditional middle approach:
- ₹10L in 5-year G-Sec: 7.15%
Similar average yield but better flexibility + rate change protection.
Strategy 3: Lock in Long-Term When Curve Flattens
Signal: Curve flattening (gap between short and long narrowing)
What to do: Move from short-term to long-term bonds
Why: When long-term bonds don't pay much more than short-term, it often means:
- Rates expected to fall
- Lock in current long rates before they drop
Example:
Scenario: Curve flattens
- 1-year: 7.0%
- 10-year: 7.1% (only 0.1% more!)
Action: Buy 10-year bond
- Lock in 7.1% for 10 years
- If rates fall to 6.5% next year, you're earning 0.6% more
- Your bond price rises (capital gain opportunity)
Strategy 4: Stay Short When Curve Inverts
Signal: Inverted curve (short-term yields > long-term yields)
What to do: Stay in short-term bonds, avoid long-term
Why:
- Recession likely coming
- Rates will fall
- Better to wait and lock in rates AFTER they fall
Example (hypothetical):
Today (inverted):
- 1-year: 7.5%
- 10-year: 7.0%
Action: Keep money in 1-year bonds
After 1 year (rates fell as predicted):
- 1-year: 6.5%
- 10-year: 6.0%
Now: Lock in 10-year at 6.0%? No - you already earned 7.5% for a year. Keep rolling short-term as rates stabilize.
Better scenario: Wait till curve normalizes, then go long-term.
Strategy 5: Laddering Across the Curve
For: Conservative investors wanting regular liquidity
How: Spread investments across different maturities
Example (₹10,00,000):
- ₹2L in 1-year G-Sec (6.9%)
- ₹2L in 3-year G-Sec (7.0%)
- ₹2L in 5-year G-Sec (7.15%)
- ₹2L in 7-year G-Sec (7.25%)
- ₹2L in 10-year G-Sec (7.3%)
Benefits:
- Something maturing every 2 years (liquidity)
- Average out interest rate changes
- Don't need to time the market
Annual action: When 1-year bond matures, buy a new 10-year bond
Reading the Current Indian Yield Curve for Investment Decisions
Current Shape (Dec 2024): Mildly upward sloping, normal
What the curve is telling us:
-
Near-term rates stable
- 3-month to 1-year yields very close (6.75-6.85%)
- Market expects RBI to hold rates
-
Moderate long-term inflation
- 10-year at 7.3% suggests 5-5.5% inflation expectation
- Not alarming, manageable
-
Stable growth outlook
- Normal curve = no recession fears
- Not exuberant growth either (curve not very steep)
-
Limited extra yield for very long bonds
- 10Y: 7.3%, 30Y: 7.4% (only 0.1% difference)
- Market doesn't see much rate risk beyond 10 years
Investment Recommendations Based on Current Curve
For Conservative Investors:
- 5-7 year G-Secs are the sweet spot
- Yield: 7.15-7.25%
- Reasonable tenure
- Decent extra yield vs 1-year (0.3-0.4%)
For Aggressive Investors:
- 10-year G-Secs at 7.3%
- Lock in rates before potential cuts in 2025-26
- Possibility of capital gains if yields fall
For Short-Term Needs:
- 364-day T-Bills at 6.85%
- Competitive yield
- Flexibility to reassess in a year
- Low interest rate risk
For Maximum Flexibility:
- Barbell: 50% in 91-day T-Bills, 50% in 10-year G-Sec
- Average: ~7.0%
- Adapt to rate changes quickly
Avoid (Currently):
- 30-year bonds: Only 7.4% - not worth 30-year commitment
- Very short: Savings account at 3-4% - better options available
Historical Yield Curve Movements in India
2019-2020: Pre-COVID Normal Curve
- 10-year yield: ~6.5%
- Shape: Normal upward slope
- Context: Stable growth, moderate inflation (4-5%)
Then COVID hit:
- March 2020: Yields spiked briefly (panic)
- April-May 2020: Yields fell sharply (RBI cuts)
- 10-year yield: Fell to 5.8%
2020-2021: Ultra-Steep Curve
- RBI repo rate: Cut to 4% (historic low)
- Short-term yields: 3-4%
- Long-term yields: 6-6.5%
- Curve: Very steep (accommodative policy)
Why steep: Market expected rates to rise eventually (inflation concerns)
2021-2022: Inflation Surprise
- Global inflation surge: Supply chain issues, commodity prices
- Indian inflation: Rose to 7%+
- Yields jumped:
- 10-year: From 6% to 7.4%
- Curve flattened: Short-term rose faster
2022-2023: RBI Tightening
- RBI hiked repo rate: 4% → 6.5% (250 basis points!)
- Short-term yields rose sharply
- Curve flattened further
- 10-year peak: ~7.6%
2023-2024: Normalization
- RBI paused hikes: Repo rate stable at 6.5%
- Inflation moderated: Back to 5-5.5%
- Yields stabilized:
- 10-year: ~7.3%
- Curve: Normal upward slope returning
Lesson: Yield curve reflects economic reality remarkably well
Common Misconceptions About Yield Curves
Myth 1: "Always buy the highest yielding maturity"
Reality: Highest yield often comes with highest risk (rate risk, liquidity risk)
Better approach: Choose maturity based on goals and curve shape
Myth 2: "Inverted curve means sell all bonds"
Reality: Inverted curve means buy long-term bonds (lock in high rates before they fall)
Example: If 10-year yields 7% and 1-year yields 7.5%, buy the 10-year - you're locking in 7% for a decade while short rates will likely fall.
Myth 3: "Yield curve only matters to traders"
Reality: Even buy-and-hold investors benefit:
- Choose better maturities
- Time large investments
- Understand economic environment
Myth 4: "Flat curve is always bad"
Reality: Flat curve is transitional - could lead to either steepening (good) or inversion (caution)
Watch RBI policy and inflation for direction.

How to Monitor and React to Curve Changes
Weekly Monitoring Routine
Every Monday:
- Check 10-year G-Sec yield (benchmark)
- Check 1-year T-Bill yield
- Calculate spread (10Y - 1Y)
Track:
- Is spread increasing (steepening) or decreasing (flattening)?
- Are yields rising or falling overall?
Action Triggers:
If spread falls below 0.3% (flattening):
- Consider locking in long-term rates
- Reduce short-term allocation
If spread exceeds 1% (very steep):
- Stay short-term
- Rates likely to rise further
- Wait for better long-term entry
If curve inverts (10Y < 1Y):
- Economic caution ahead
- Lock in long-term bonds
- Reduce equity exposure
Don't Overreact to Daily Moves
Noise vs Signal:
- Daily: ±0.05-0.10% is normal (noise)
- Weekly: ±0.20%+ is significant (signal)
- Monthly: ±0.50%+ is major shift (strong signal)
Example:
- Monday: 10Y at 7.30%
- Friday: 10Y at 7.35%
- Change: +0.05% (5 basis points)
- Action: None needed (normal fluctuation)
vs
- January: 10Y at 7.30%
- March: 10Y at 7.80%
- Change: +0.50% (50 basis points)
- Action: Review portfolio, consider implications
