Why Rising Bond Yields Put Pressure on Stock Prices

Hello, I am CS Sandeep Kumar, and today’s topic is Bond Yields and Equity Valuations. In this video, we will learn what bond yields are, why bond prices and yields move in opposite directions, the importance of the 10-year G-Sec yield, US bond yields and their impact on Indian markets. We will also understand the relationship between bond yields and DCF valuation, their impact on banks, and how rising yields can influence equity valuation multiples. 

So, let’s begin.  A company may report strong earnings and healthy business growth, yet its stock price may still decline. Why does this happen? Many times, the answer is not found in the company’s financial statements, but in the bond market. This is because bond yields influence several important market variables, including risk-free returns, the cost of capital, FII flows and equity valuations, which can eventually impact stock prices.  If you understand this relationship, the logic behind many seemingly confusing market movements becomes much clearer. 

What Are Bond Yields? 

Every investor has multiple options for allocating capital, including equities, real estate, fixed-income products and government bonds. It is this comparison between different asset classes that makes bond yields important. In simple terms, a bond is a loan. When you buy a government bond, you are effectively lending money to the government and receiving interest in return. This return is broadly referred to as the bond yield.  For equity investors, however, the importance of bond yields lies not merely in their definition but in their implications. 

Bond yields tell us how much return is available from a relatively low-risk investment. This return acts as an important benchmark for equity valuations.  If risk-free returns become more attractive, investors are likely to expect higher returns from equities as compensation for taking additional risk. This makes it more difficult for the market to justify very high valuation multiples. This is why understanding bond yields is important for serious investors. Many times, changes in stock valuations begin with movements in bond yields. 

Why Bond Prices and Yields Move in Opposite Directions 

Bond prices and bond yields move in opposite directions. Suppose a bond is priced at ₹100 and pays ₹7 in annual interest. When the bond trades at ₹100, the yield is 7%. Now, if demand for the bond increases and its price rises to ₹110, the same ₹7 interest payment represents a lower yield. On the other hand, if the bond price falls to ₹90, the same ₹7 interest payment represents a higher yield. So, when bond prices rise, yields fall, and when bond prices fall, yields rise. This inverse relationship is a fundamental principle of the bond market. Through this mechanism, the market continuously prices change in interest rates, inflation expectations and the economic outlook. 

Why the 10-Year G-Sec Yield Matters 

If there is one bond yield in India that investors should closely track, it is the 10-year Government Security yield, commonly known as the 10-year G-Sec yield. This is the yield on a long-term Government of India bond and is considered one of the most important benchmarks in Indian financial markets. Why does the market attach so much importance to this one number? The 10-year G-Sec yield performs three important roles. It acts as a benchmark interest rate, a reference for risk-free returns and a valuation reference point. Banks, mutual funds, insurance companies, FIIs and corporates all closely monitor this yield. When the 10-year G-Sec yield moves, its impact gradually spreads across the financial system. It can influence corporate borrowing costs, loan rates, equity valuations, capital flows and, ultimately, stock prices. This is why it can be difficult to fully understand the equity market without understanding the bond market. The 10-year G-Sec yield is one of the few macroeconomic indicators that can influence almost every asset class. 

Bond Yields and Risk-Free Returns 

Let us now understand how bond yields can directly influence equity valuations. 

Suppose an investor has two options. Option A is a 10-year G-Sec offering a yield of 7%, while Option B is an equity investment with an expected return of 11%. By taking the additional risk associated with equities, the investor is expecting approximately 4% additional return. Now suppose the bond yield increases from 7% to 9%, while the expected equity return remains at 11%. The additional reward for taking equity risk has now reduced to just 2%. This is where valuation pressure can begin. Investors always evaluate returns in the context of risk. When returns from relatively low-risk assets improve, equities must either deliver faster earnings growth or valuations must adjust for them to remain attractive.  The relationship is straightforward. When bond yields rise, risk-free returns rise, the relative reward for taking equity risk reduces and equity valuations can come under pressure. This is why stocks do not compete only with other stocks. They also compete with bonds.  

In many cases, a market correction may not be caused by weak earnings at all. Rising bond yields themselves can put pressure on valuations. 

Bond Yields and the Cost of Capital 

Now, let us look at bond yields from a company’s perspective. The impact of bond yields is not limited to investors. They can also directly affect businesses.  When government bond yields rise, borrowing costs across the economy can also move higher. Banks may charge higher lending rates, corporate bonds may need to be issued at higher yields, and raising debt can become more expensive.  The impact is generally greater on sectors that are capital-intensive or highly leveraged, such as real estate, infrastructure, telecom, capital goods and utilities. In these businesses, debt can be an important source of funding for growth. Therefore, even a relatively small increase in borrowing costs can have a meaningful impact on profitability. 

The relationship can be understood as a chain. When bond yields rise, the cost of debt can rise, interest expenses can increase, profitability may come under pressure and valuations can also be affected.  Companies with strong balance sheets are generally more resilient, while highly leveraged businesses can face greater pressure. 

Bond Yields and Banks 

Now, let us understand how bond yields impact the banking sector. Banks hold government bonds as well as provide loans. Therefore, changes in bond yields can directly affect them. When bond yields rise, bond prices fall. This can temporarily reduce the value of bonds held in a bank’s investment portfolio.  On the other hand, higher interest rates can also allow banks to issue new loans at higher lending rates, which may support profitability. This means the impact of rising yields on banks can be mixed. In the short term, banks may face treasury losses, while healthy credit growth and better lending spreads can support profitability. 

US Bond Yields and Indian Markets 

Let us now discuss a factor that many investors tend to underestimate: US bond yields.  Global capital generally moves towards opportunities offering better risk-adjusted returns. This is why movements in US Treasury yields can also affect Indian markets. Suppose the US Treasury yield rises from 3% to 5%. Investors can now earn a higher return from relatively safe US government bonds. As a result, some global capital may move from emerging markets towards US assets. The relationship is simple. When US yields rise, US assets become relatively more attractive. Capital flows towards emerging markets may slow, liquidity can reduce and markets may come under pressure. At the same time, the US dollar can strengthen, putting pressure on emerging-market currencies, including the Indian rupee. This is why not every market correction is driven by domestic factors. There can be periods when earnings and economic data remain strong, yet markets still come under pressure because of rising US bond yields. 

Bond Yields and Equity Valuation: The DCF Connection 

Now, let us come to the point where bond yields begin to directly influence stock valuations. This involves an important concept called Discounted Cash Flow, or DCF. The valuation of a company is based partly on the cash flows it is expected to generate in the future. However, there is a basic principle to remember: receiving ₹100 today and receiving ₹100 ten years from now do not have the same value. This is why future cash flows are converted into their present value using a discount rate. 

This is where bond yields become important because the discount rate is generally built around a risk-free rate, for which government bond yields act as an important reference. When bond yields rise, discount rates can also rise. A higher discount rate reduces the present value of future cash flows, which can lead to lower valuations. 

This is why a company’s business performance and earnings estimates may remain unchanged, yet its valuation multiple can still decline. In other words, the valuation multiple can contract. Another important point is that rising yields do not affect all companies equally. The impact is generally greater on businesses whose valuations depend heavily on future growth expectations. Examples include technology companies, high-growth businesses and new-age companies.  The valuations of these companies tend to depend more heavily on future cash flows. Therefore, when discount rates rise, their valuations can come under greater pressure.  In simple terms, when the discount rate increases, future cash flows become less valuable in present-value terms, which can put pressure on growth-stock valuations. 

This is one reason why technology and growth stocks can underperform in a rising-yield environment. There can be situations where the underlying business remains strong and revenue growth remains healthy, yet stock prices decline. In such cases, the reason may not be weaker earnings but valuation compression. 

Conclusion 

In this video, we learnt that bond yields influence risk-free returns, the cost of capital, FII flows and equity valuations. We understood the importance of the 10-year G-Sec yield, US bond yields and the relationship between bond yields and DCF valuations. Most importantly, we learnt that rising bond yields can put pressure on equity valuation multiples, particularly for growth stocks. In the next chapter, we will discuss Pricing Power: The Real Moat. We will decode that in the next chapter.
