I am not familiar with the industry, do banks like BofA own these risky loans? Trying to see who is going to get screwed when people start foreclosing.
Usually what happens is a mortgage broker or a smaller bank originates a mortgage. They then sell those loans, whole, to larger institutions, say somebody like Countrywide. Countrywide turns around and bundles those loans up into asset pools and puts them into trusts and issues bonds backed by those mortgages. All of the cash, principal and interest, from those loans goes to paying back the bonds or paying interest due.
Any asset that generates a future benefit, or cashflow, can be securitized. Student loans, home-equity loans/line of credit, credit cards, car leases, car loans, installment loans, timeshare loans, David Bowie even issued bonds backed by his future royalty and concert revenues.
The mortgages that are sold in the trust are moved off of the bank's balance sheet, they are now the property of the bondholder/investors. The bank records a small (or sometimes large) profit and retains a small piece of what is left of the interest, called the IO strip (interest only). They also usually service (collections, payment receipt) those loans, so they make money off of that.
The main process by which companies move these loans off balance sheet is FAS 140, which is a statement and accounting guidance put out by FASB.
Now, the IO strip, the remainder of the interest that isn't paid to bondholder/investors, and isn't consumed by defaults, gets paid to the bank. This revenue, paid up-front, can run into the hundreds of millions of dollars of revenue. However, it is highly volatile, since changes in interest rates or defaults could make the bank "write it down", or revise their assumptions. This change can impact earnings to a huge degree. So it's a double-edged sword, you make a ton of money up front but could pay for it in back.
Now, companies like Bank of America aren't huge mortgage backed security issuers. In fact BoA is a smaller player and most of their mortgages are very high quality, they often sell a lot to FNMA or other agencies. BoA is a very conservative bank.
If you want to look for bellweathers of the MBS market or housing in general, look at places like Countrywide, Ameriquest, or National City (acquired by Merrill Lynch). They are already starting to cut costs and revise earnings estimates.
Now, FNMA only acquires certain types of mortgages, called "conforming", they adhere to the highest standards of credit. High FICO, higher down payments, higher equity, better property, higher income...etc. The next classification is Alt-A, which is usually loans that didn't quite meet "conforming" standards, so FNMA wouldn't buy them even to later securitize them.
The final classification, B/C, are the true garbage of the industry. They are the ones with missing documents, 2nd liens, poor income ratios, high value, high risk, low fico...etc. Agencies won't touch these.
