Crowding Out Effect
What It Is:
The crowding out effect describes the idea that large volumes of government borrowing push up the real interest rate, making it difficult or close to impossible for individuals and small companies to obtain loans.
How It Works/Example:
The theory behind the crowding out effect assumes that governmental borrowing uses up a larger and larger proportion of the total supply of savings available for investment. Because demand for savings increases while supply stays the same, the price of money (the interest rate) goes up.
Crowding out begins to take effect when the interest rate level reaches a point at which only the government can afford to borrow. Unable to compete for loans under such circumstances, individuals and smaller-scale companies are forced (crowded) out of the market.
Why It Matters:
Because crowding out leads to decreases in private sector consumption and, therefore, slows economic growth, the crowding out effect should be a serious consideration for any government that plans to get an increasing percentage of its funding through the capital markets.
