Given his good credit rating, the bank is willing to give the second American a loan. The bank gives the loan at a certain rate of interest.
The second American then divides this loan into a lot of small portions and gives them out as home loans to lots of other Americans -- like the first American -- who do not have a great credit rating and to whom the bank would not have given a home loan in the first place.
The second American gives out these loans at a rate of interest that is much higher rate than the rate at which he borrowed money from the bank. This higher rate is referred to as the sub-prime rate and this home loan market is referred to as the sub-prime home loan market.
