With US interest rising, the EMIs too increased. Higher EMIs hit the sub-prime borrowers hard. A lot of them in the first place had unstable incomes and poor credit rating.
They, thus, defaulted. Once more and more sub-prime borrowers started defaulting, payments to the institutional investors who had bought the financial securities stopped, leading to huge losses.
The problem primarily began with the United States keeping its interest rates very low for a very long time, thus encouraging Americans to go in for housing loans, or mortgages. Lower interest rates led to buyers wanting to take on bigger loans, and thus bigger and better homes.
