Crowding Out

Crowding out is the fall in private investment that happens when government borrowing pushes up real interest rates.

When the government runs a deficit it borrows in the loanable funds market, raising the demand for loanable funds and the real interest rate. The higher rate discourages private investment and interest-sensitive spending, partly offsetting the expansionary fiscal policy. It is a key limitation of deficit-financed government spending.

Formula / Example

Higher deficit → ↑ demand for loanable funds → ↑ real interest rate → ↓ private investment.
