At the equilibrium interest rate, the quantity of loanable funds supplied equals the quantity of loanable funds demanded. Here, the equilibrium interest rate is 8%, with $300 billion of funds lent and borrowed. Lenders who demand an interest rate of 8% or lower have their offers of loans accepted; those who demand a higher interest rate do not. Projects that are profitable at an interest rate of 8% or higher are funded; those that are profitable only when the interest rate falls below 8% are not.
