Introduction
It is entirely possible for an equity market to
perform poorly when bond yields are rising, even when economic growth remains
reasonably strong. The relationship is not mechanical, but rising bond yields
can change the relative attractiveness of equities, increase the cost of
capital, reduce valuations and make investors demand a higher return for taking
equity risk. The crucial issue is not simply whether yields are high, but why
they are rising and what investors expect them to do next. If yields rise
because inflation expectations are increasing, investors may fear that central
banks will maintain restrictive monetary policy for longer. If yields rise
because real economic growth and productivity are improving, the effect on
equities can be much less negative. Thus, a rising-yield environment can
coexist with a rising stock market, but persistent increases in yields without
corresponding improvements in earnings expectations can create a powerful
headwind for equity investment.
Why Rising Bond Yields Can Hurt Equities
The most direct mechanism is the opportunity cost of
capital. Government bonds are generally viewed as relatively safer assets than
equities. When a 10-year government bond yields 6%, an investor may demand a
substantially higher expected return from equities to justify taking additional
risk. If the bond yield rises to 7%, the required return on equities may also
increase. This can reduce the price investors are willing to pay for a given
level of corporate earnings. The effect is particularly important for companies
whose profits are expected far into the future. Higher discount rates reduce
the present value of those future cash flows, putting pressure on technology,
growth and other high-valuation companies. Therefore, an equity market can
experience falling price-to-earnings ratios even when corporate profits are
still growing.
The Expectations Channel Is More Important Than the
Yield Alone
The most important distinction is between the level of
bond yields and expectations about future yields. If investors believe that a
7% yield is temporary and that inflation and interest rates will eventually
decline, equity investment may remain strong. Conversely, if investors believe
that today's 7% yield will become the new normal, equity valuations can remain
depressed for a prolonged period. Expectations influence investment decisions
before actual monetary-policy changes occur. A company deciding whether to
build a factory, a household deciding whether to invest savings in mutual funds
and an institutional investor allocating capital between bonds and equities are
all responding partly to expected future returns. Consequently, an economy can
have adequate liquidity today while equity investment remains weak because
investors anticipate higher financing costs tomorrow.
When Rising Yields Do Not Necessarily Mean a Weak
Stock Market
Rising yields are not automatically bad news for
equities. Suppose nominal GDP is accelerating because productivity, employment
and real incomes are improving. Corporate revenues and profits may rise
sufficiently to offset the increase in financing costs. In that environment,
bond yields can rise because investors expect stronger growth rather than
because they fear persistent inflation. Historically, some of the strongest
equity-market periods have occurred alongside increasing interest rates because
earnings growth was even stronger. The problem arises when yields rise faster
than earnings expectations. If a company's expected earnings increase by 5% but
its required return rises sharply, its valuation may fall despite higher
profits. Thus, the relevant relationship is between earnings growth, expected
returns and the risk-free rate, rather than between equity prices and bond
yields alone.
The Indian Problem: Financial Savings and Corporate
Investment
For India, the issue is particularly important because
the country needs large amounts of domestic financial savings to finance
private investment. Household savings can flow into bank deposits, government
securities, insurance, mutual funds, equities, gold and property. If safe
fixed-income instruments begin offering attractive real returns, households may
become less willing to accept equity-market volatility. This can reduce the
flow of incremental savings into equities. At the same time, if bond yields
rise because inflation expectations are becoming entrenched, companies face
higher borrowing costs. That can discourage new factories, expansion and
employment. The result can become self-reinforcing: higher yields reduce
valuations, weaker equity valuations reduce risk appetite, weaker risk appetite
reduces equity financing, and weaker investment eventually constrains future
growth.
Why Equity Investment Matters Beyond the Stock Market
Equity investment should not be viewed merely as a
mechanism for increasing stock-market indices. Equity capital is especially
important for financing entrepreneurial activity and productive capacity.
Unlike debt, equity does not require fixed interest payments and therefore
allows companies to undertake riskier long-term projects. New businesses,
manufacturing enterprises, technology companies and infrastructure-related
ventures often require patient capital before they generate stable cash flows.
A healthy equity market therefore supports the real economy by transferring
household and institutional savings toward productive enterprises. If investors
become excessively attracted to bonds, gold or real estate, the economy may
lose an important source of risk-bearing capital.
How to Boost Equity Investment
The first requirement is to restore confidence in long-term
returns rather than artificially suppress bond yields. Attempts to force
investors into equities by keeping interest rates artificially low can create
inflation and financial instability. A better strategy is to maintain credible
macroeconomic conditions in which inflation expectations remain anchored and
long-term interest rates are predictable. Investors are more willing to commit
equity capital when they believe that monetary policy, taxation, regulation and
exchange-rate conditions will remain reasonably stable.
The second requirement is to increase the
profitability and productivity of Indian companies. Equity investment
ultimately follows expected earnings. Tax incentives alone cannot permanently
create a bull market. Higher labour productivity, better infrastructure,
cheaper logistics, reliable electricity, easier business conditions,
technological innovation and skilled workers can raise corporate profitability
and therefore justify higher equity valuations. The strongest way to support
the stock market is consequently to strengthen the underlying productive
economy.
The third requirement is to broaden household
participation in financial assets. India has enormous household savings, but a
substantial proportion remains outside equities and formal financial markets.
Greater financial literacy, simple investment products, transparent mutual
funds, low-cost pension products and systematic investment mechanisms can
gradually shift savings toward productive financial assets. However, this must
be accompanied by proper risk disclosure. Encouraging households to buy
equities without explaining market risk would merely transfer losses to
inexperienced investors.
Making Equities More Attractive Than Speculation
Equity investment also becomes stronger when investors
believe that companies will use capital productively. Corporate governance,
transparent accounting, predictable taxation and protection of minority
shareholders are therefore not peripheral issues. They directly influence the
equity risk premium. If investors believe that corporate governance risks are
high, they demand a larger return before purchasing shares. Better governance
can reduce that risk premium and increase valuations without requiring lower
bond yields. Similarly, deeper corporate-bond markets can help companies
diversify financing and reduce excessive dependence on bank credit, allowing
equity markets to perform their proper risk-sharing function.
The Role of Government and the RBI
The government and RBI should therefore focus on stability
of expectations rather than attempting to control asset prices directly. If
long-term inflation expectations are stable, real interest rates are
reasonable, the rupee is not subject to disorderly depreciation and fiscal
borrowing remains credible, bond yields can rise without necessarily destroying
equity investment. The objective should be to create a situation in which
investors believe that long-term economic growth will generate corporate
earnings faster than the increase in the cost of capital. Monetary policy
should avoid both excessive financial repression and unnecessary monetary
tightening. Fiscal policy should prioritize productive public investment that
raises private-sector productivity rather than merely increasing demand.
Conclusion
A stock market can certainly fail to perform while
bond yields are rising. The critical question is whether rising yields reflect
stronger growth or worsening inflation and risk expectations. If yields rise
because investors expect persistent inflation, tighter monetary policy and
higher future financing costs, equity valuations can suffer even when headline
GDP growth remains strong. But rising yields need not be the enemy of equities
when they accompany stronger productivity, earnings and real incomes. The
sustainable solution is therefore not simply to push bond yields lower. It is
to make equity returns more credible by improving the economy that generates
those returns. Stable inflation expectations, productive investment, stronger
corporate earnings, deeper financial markets, better governance and broader
household participation can redirect savings toward equities. Ultimately, the
best way to make the equity market perform is to make investors believe that
India's future productive capacity—and consequently corporate profits—will grow
faster than the cost of capital.
