Bond Yields Today: How to Read Yield Movements & What Drives Them

Introduction

Bond yields are among the most closely watched indicators in financial markets.

They reflect interest rate expectations, inflation outlook, economic conditions, and investor sentiment.

Understanding bond yields today helps provide clarity on both short-term market behaviour and longer-term interest-rate trends.

This article explains how bond yields work, why they move, and how government bond yields differ from corporate bond yields.

What Are Bond Yields?

A bond yield represents the return an investor expects to earn if a bond is held until maturity.

Key takeaways

Yield is expressed as an annual percentage.

It reflects the relationship between price and coupon.

Yield changes when bond prices change in the market.

Bond yields act as benchmarks for loans, deposits, and other financial products.

Types of Bond Yields

1. Coupon Yield

Coupon ÷ Face Value

Shows the interest rate fixed at issuance.

2. Current Yield

Coupon ÷ Current Market Price

Reflects income relative to the latest traded price.

3. Yield to Maturity (YTM)

Total expected return if held to maturity.

This is the most widely used measure when examining bond yields today.

How to Read Bond Yields Today

When viewing bond yields, investors typically check:

Current YTM of frequently traded bonds

Price movements relative to yesterday

Yield spreads between different maturities

Benchmark yield levels such as the 10-year G-Sec

Daily movement is expressed as “+X bps” or “–X bps”, where 1 basis point = 0.01%.

Government Bond Yields vs Corporate Bond Yields

Government Bond Yields

Issued by the Government of India

Minimal credit risk

Used as risk-free benchmark rates

Yields reflect macroeconomic expectations

Corporate Bond Yields

Issued by corporates (AAA to lower ratings)

Include credit-spread premium over government bonds

Yield difference compensates for credit and liquidity risk

Why corporate bond yields are higher

Because investors require a premium for corporate default risk, even for high-rated issuers.

Yield Curves Explained

A yield curve shows the relationship between yields and maturities.

Common shapes:

1. Upward-sloping curve

Longer maturities have higher yields.

This reflects growth expectations and inflation.

2. Flat curve

Short- and long-term yields are similar.

Often signals economic uncertainty.

3. Inverted curve

Short-term yields exceed long-term yields.

Historically associated with slowdown indicators.

The shape of the yield curve helps interpret interest-rate expectations.

Key Factors Driving Yield Movements

Bond yields respond to multiple drivers:

1. Inflation Outlook

Higher inflation pushes yields upward.

2. Monetary Policy

Changes in repo rate or RBI guidance affect yield levels.

3. Government Borrowing

Large borrowing programs can influence supply and yields.

4. Economic Growth Trends

Strong growth may push yields higher; slower growth may lower them.

5. Global Market Trends

Changes in U.S. Treasury yields often influence Indian yields.

6. Crude Oil Prices

Higher oil prices may raise inflation expectations and impact yields.

7. Liquidity in the Banking System

Surplus liquidity often lowers yields; deficit liquidity pushes them up.

Understanding these factors helps contextualize current bond yields.

How Monetary Policy Impacts Yields

Bond yields respond directly to central bank actions.

When RBI raises rates

borrowing costs rise

bond prices fall

yields increase

When RBI cuts rates

bond prices rise

yields fall

Market expectations about future policy often move yields even before announcements.

Market Liquidity & Demand–Supply Effects

Liquidity plays a major role in bond yields today:

High demand → prices rise → yields fall

Low demand → prices fall → yields rise

Liquidity varies across:

government bonds

PSU bonds

high-rated corporate bonds

lower-rated corporate bonds

Benchmark government bonds typically have the highest liquidity.

Credit Ratings & Spread Behaviour

Corporate bond yields include a credit spread over government bonds.

Spread widens when:

economic conditions weaken

corporate risk increases

liquidity reduces

Spread narrows when:

credit outlook strengthens

demand for corporate bonds increases

AAA-rated corporate yields will typically be closest to government bond yields, while lower-rated bonds show higher spreads.

Yield-to-Maturity vs Current Yield

These terms are often confused:

Current Yield

Reflects income only (coupon ÷ price).

Yield to Maturity

Reflects:

coupon income

capital gain/loss

time value of money

YTM is the standard measure used when discussing current bond yields.

Why Price and Yield Move Opposite

Bond math creates an inverse relationship:

When prices rise, yields fall.

When prices fall, yields rise.

This happens because the fixed coupon becomes more or less attractive relative to new market interest rates.

Risks to Consider When Studying Yields

1. Interest-Rate Risk

Longer maturities are more sensitive.

2. Reinvestment Risk

Coupons reinvested at lower rates reduce overall return.

3. Credit Risk (for corporate bonds)

Lower credit quality → higher yields.

4. Liquidity Risk

Wider bid–ask spreads can distort yield clarity.

5. Inflation Risk

Unexpected inflation affects real yields.

Common Misinterpretations

Misinterpretation 1: Higher yield always means better value

Higher yields often indicate higher risk.

Misinterpretation 2: Corporate and government yields behave similarly

Corporate yields include credit spreads; government yields reflect macro drivers.

Misinterpretation 3: Yield curves always slope upward

Curve shapes change with economic cycles.

Misinterpretation 4: Current yields reflect future returns

Yields can change rapidly based on policy or economic data.

Conclusion

Bond yields play a central role in understanding market sentiment, interest-rate expectations, and overall economic direction.

By learning how bond yields today are formed—across government and corporate markets—it becomes easier to interpret yield movements and evaluate how they fit into broader financial analysis.

Understanding yield curves, credit spreads, monetary policy effects, and price–yield relationships provides a strong foundation for studying India’s bond market.
