First, interest rates drop quickly by approximately one-quarter. Interest rates include compensation to the lender for the tax that they must pay on interest you pay them. That is why taxable bonds bear a higher interest rate than tax-exempt bonds. When the tax on interest is removed, interest rates will drop toward today’s tax-exempt rate.

Second, under the current system, savings and investments are taxed. Under the FairTax, savings and investments are not be taxed at all. As Americans save more money, the pool of funds in lending institutions grows. When you add to this the flood of capital currently trapped offshore, we realize a huge increase in the pool of capital, thereby causing the cost of borrowing funds to drop.
