Which explanation best describes why a lender may charge interest?
Correct answer
Answer D: For giving up use of the money and taking repayment risk.
Quick explanation
The lender cannot use the money themselves for a while and risks not getting all of it back. Interest can provide compensation for this.
Detailed explanation
Someone lending money cannot use it themselves to the same extent during the agreed term. They temporarily give up other possibilities, such as making a purchase or keeping an accessible reserve. This temporary use by someone else can justify compensation.
There is also a risk that the debtor will not repay in full or on time. Interest can account for this risk but does not remove it. A high promised interest rate is therefore not proof of safe repayment.
The actual terms depend on the agreement and other factors such as duration, collateral and market conditions. Giving up present use and taking default risk explain possible reasons for interest, but do not fully explain every interest rate.
Example or everyday application
You lend an amount for one year. During that time, it is unavailable for your own spending, and repayment depends on the debtor fulfilling the agreement.
Key takeaway
Interest can compensate for temporarily giving up use and for default risk.
