Model Answer

Introduction

The sovereign bond market plays a critical role in the financial architecture of an economy by enabling governments to raise long-term capital. Bond yields are closely monitored because they reflect investor expectations regarding inflation, liquidity, economic growth, and monetary policy. In fixed-income markets, bond prices and bond yields exhibit an inverse relationship.

Body

A bond is a fixed-income instrument that pays a predetermined coupon to investors. Once issued, bonds are traded in the secondary market where their prices fluctuate according to prevailing market conditions.

The inverse relationship between bond prices and yields can be understood through the fixed coupon mechanism. Suppose a government bond with a face value of ₹1000 carries a fixed annual coupon of 7%. If market interest rates rise to 8%, newly issued bonds become more attractive as they offer higher returns. Consequently, the older bond loses demand, forcing its market price to fall below face value. Since the coupon payment remains fixed at ₹70, the effective return or yield for the new buyer increases.

Conversely, when interest rates decline, existing higher-coupon bonds become attractive, increasing their demand and market price while lowering yields.

In India, the Reserve Bank of India (RBI) significantly influences sovereign bond yields through monetary policy instruments such as repo rate adjustments and liquidity management operations. During periods of inflationary pressure, the RBI may raise policy rates to contain inflation. This leads to higher government security (G-Sec) yields as investors demand better returns to compensate for inflation risks.

Similarly, elevated bond yields increase government borrowing costs and can crowd out private investment by raising overall interest rates in the economy. Bond yields also affect banking sector profitability, corporate borrowing costs, and foreign portfolio investment flows.

Conclusion

Therefore, sovereign bond yields function as a key transmission channel of monetary policy and an important indicator of macroeconomic stability. Their movement reflects changing expectations regarding inflation, fiscal conditions, and economic growth in India.
