Answer by Hello G
For any mortgage there is a “default risk”, which is the risk that the person who owns the house will not be able to pay the mortgage. Banks use mortgage backed securities to bundle the risk of the mortgages and transfer the risk of the mortgages to others who are better able to bear it. (We know that they are better able to bear it because they are willing and able to pay for them.)

What happened with the current crisis (part of it) is that these mortgage-backed securities became structured in crazier and crazier ways, swapped for other risk-transfer securities called Credit Default Swaps, and so muddled that it was difficult to put a value on the assets. Eventually people realized what was going on and were no longer willing and able to buy those securities (that is called a liquidity problem). The banks were stuck holding the ball and were no longer able to sell those securities for cash, which they would lend out to companies and individuals. So, that is where some of the credit crisis comes from.

EDIT: I heard a great radio program about this, with experts explaining in very easy to understand terms. I will link to the podcast below. The hour-long show is DEFINITELY worth listening to.
