Interest Rate (Policy Rate)
The price of borrowing money — the policy rate set by the central bank is the basis for loans, deposits, bonds, and stock valuation.
In plain terms
An interest rate is "the price of borrowing money." Borrow and you pay interest; deposit and you earn it. That ratio is the rate. Among them, the policy rate set by the central bank (the Fed in the US) is the starting point for all rates.
When the policy rate rises, loan rates, deposit rates, and bond yields follow. Think of it as the dial that sets the "price of money" for the whole economy.
What it tells you
Rates are the basis for stock valuation. When rates rise, safe deposit and bond interest improves, lowering the relative appeal of risky stocks. Growth stocks, whose value pulls distant future earnings forward, are especially sensitive (their future cash flows get discounted more heavily).
A heavily indebted company sees its interest burden swell fast when rates rise. So in a rising-rate phase, debt-to-equity and net debt become the variables that separate a company's fitness.
Formula
policy rate = the rate set by the central bank (the Fed in the US) market rates, loan/deposit rates, and bond yields move based on it
What high or low means
Raising rates (tightening) is read as cooling overheating and inflation; cutting them (easing), as reviving the economy. The direction of rates heavily sways the whole market mood.
In a rising-rate phase, companies with little debt and solid cash flow are seen as relatively favored; in a falling-rate phase, growth stocks (it is not absolute).
Both the "direction" and the "speed" of rates matter. The same 5% reached fast and a 5% that has held for a while shock the market differently. Read the flow, not one point.
A rate's effect on stocks can be opposite by industry. A bank's net interest margin can improve when rates rise, while real estate and utilities that run on debt feel a bigger burden.
Rates are a macro variable and hard to predict. This term is background for reading market and earnings news. (※ Our screen centers on individual companies' SEC-filed financials and does not provide rate indicators themselves.)
