One example of financial intermediation is the selling of mortgages by banks to a third party. If you borrow money from the Bank of America to buy a house, the bank immediately sells your mortgage to a third party like Fannie Mae. This transaction gives Bank of America the cash to make another mortgage. Fannie then holds your loan along with millions of others they have bought, and they use the loans as assets to serve as collateral, so they can borrow money in the financial markets to buy more loans from Bank of America and other lenders. What is the impact of all this activity on the cost and availability of mortgages? What if any pitfalls do you see in the process? On balance, is it good or bad for society? Why?
