Here is how bond yield impacts the stock market:
Cost of capital
The cost of capital (COC) is the rate of return a company requires to cover the opportunity cost of borrowing money through bonds. A higher cost of capital may reduce profitability and result in a slower expansion for a business, negatively impacting stock prices. When bond yields rise, interest rates often increase, making borrowing more expensive for companies and increasing their cost of capital. On the other hand, when bond yields fall, borrowing becomes cheaper for companies, lowering their cost of capital.
Opportunity cost
When bond yields rise above and showcase a return potential higher than stocks, investing in bonds becomes more attractive for investors than investing in stocks. The opportunity cost of holding stocks increases as investors could earn safer, guaranteed returns by investing in bonds. This leads to a sell-off in the stock market and higher investments in bonds. Conversely, when bond yields fall, the return on bonds becomes less attractive for investors, who look towards investing more in stocks. The opportunity cost of holding bonds rises, and investors may sell their bonds to invest the amount in stocks.
Foreign funds
Bond yields positively impact the amount of funds invested by foreign Institutional Investors (FIIs) in India. When bond yields rise in India, the higher return potential attracts foreign investors looking for higher returns on safer investments. They generally sell a portion of their investments and invest the amount in Indian bonds, especially in government bonds, which are considered the safest. This can lead to a decrease in foreign investment in stocks. On the other hand, when bond yields fall, the return bonds become less attractive to foreign investors, forcing them to shift their funds to higher-yielding assets like stocks or seek opportunities in other countries. This can increase foreign inflows into the stock market, boosting stock prices.
