Final answer:
When the interest rate falls, the quantity of loanable funds demanded increases as borrowing costs are lower and more people are inclined to take out loans.
Step-by-step explanation:
As the interest rate falls, the quantity of loanable funds demanded increases. This is in accordance with the law of demand, which states that a lower cost of borrowing leads to a higher quantity demanded. When interest rates decrease, borrowing becomes cheaper, resulting in more individuals and businesses seeking loans.
The financial markets operate on this basic principle of demand and supply: lower interest rates tend to incentivize more borrowing as the cost of taking out loans is reduced.
