der Leitzins, -en

Definition & meaning

The Leitzins (plural: Leitzinsen) refers to the key interest rate or base interest rate set by a central bank. It is the primary tool used by monetary authorities—such as the European Central Bank (ECB) in the Eurozone or the Federal Reserve in the United States—to control the money supply, manage inflation, and influence economic activity.

By adjusting this rate, the central bank influences the interest rates that commercial banks charge for loans or offer for savings.

• If the Leitzins is high, borrowing becomes more expensive, which typically slows down investment and consumption, helping to combat inflation.
• If the Leitzins is low, borrowing becomes cheaper, which stimulates economic growth and investment.

Grammar & Word origin

The word is a masculine compound noun (der Leitzins). It is formed by two parts:

1. Leit-: Derived from the verb leiten ↗ (to lead, to guide, to direct).
2. Zins: Meaning interest (the price paid for borrowing money).

Together, it literally translates to "guiding interest," as it acts as the benchmark rate that guides the entire interest rate structure of an economy.

• Leitzinssatz ↗ (a more formal synonym for the key interest rate).
