Interest Rate (Policy Rate)

Interest Rate

At a glance

The price of borrowing money — the policy rate set by the central bank forms the base for loans, deposits, bonds, and how stocks are valued.

Policy rate = the rate set by the central bank (the Fed in the US)

Raising rates (tightening) is read as an attempt to cool overheating and prices; lowering them (easing) is read as an attempt to revive the economy.

In plain terms

An interest rate is "the price of borrowing money." Borrow money and you pay interest; deposit it and you receive interest. That ratio is the interest rate. Among them, the policy rate set by the central bank (the Fed in the US) is the starting point for all other rates.

When the policy rate rises, loan interest, deposit interest, and bond yields tend to rise along with it. Think of it as the dial that sets the "price of money" for the whole economy.

What it tells you

Interest rates are the foundation of how stocks are valued. When rates rise, interest on safe deposits and bonds improves, so the relative appeal of riskier stocks falls. Growth stocks, which are valued by pulling far-off future profits into the present, are especially sensitive to rates (because future cash flows get discounted more heavily).

For companies with a lot of debt, interest costs climb quickly when rates rise. That is why, in a rising-rate period, the debt ratio and net debt become variables that separate companies by financial strength.

Formula

Policy rate = the rate set by the central bank (the Fed in the US)
Market rates, loan rates, deposit rates, and bond yields move on top of it

What high or low means

Raising rates (tightening) is read as an attempt to cool overheating and prices; lowering them (easing) is read as an attempt to revive the economy. The direction of rates has a large influence on the overall mood of the market.

In a rising-rate phase, companies with little debt and steady cash flow are often seen as relatively favored, and in a falling-rate phase, growth stocks are (though this is not absolute).

Caution

Even at the same 5%, a 5% reached quickly and a 5% that has stayed for a long time hit the market differently. The direction and speed of rates show up in the trend, not in a single number.

The effect of rates on share prices can be the exact opposite depending on the sector. Banks may see their loan-deposit margins improve when rates rise, while real estate and utilities, which run on debt, face a heavier burden.

Interest rates are a macro variable and are hard to forecast. This term is background knowledge for reading market and earnings news. (※ Our screens center on individual companies' SEC-filed financials, and we do not provide interest-rate data itself.)

Metrics to read alongside

Inflation

Central banks usually move rates in order to control prices (inflation). The two move as a pair, so looking at the trend in prices gives a sense of where rates may go next.

Debt-to-Equity Ratio (D/E)

When rates rise, the interest burden on companies with a lot of debt grows quickly. In a rising-rate period, the debt ratio becomes a key clue to how long a company can hold up.

DCF (Discounted Cash Flow)

The discount rate used to value a company with DCF depends heavily on interest rates. When rates rise, the same future earnings are worth less in present-value terms, so the estimated fair value falls — especially for growth stocks.
