But again your premise is wrong. There is a finite projected income stream, the interest. you can only sell it once. There is no duplication, or extra, look at my example above. An instrument can move between financial institutions, but no one will buy it if it doesn't give them some profit. A lot of it is done using PV and FPV calcs, and imputed interest rates.Tuco wrote:Bank B then sell it on to Bank C.

Bank A then sells the bit of paper containing the agreement to Bank B for £5,000. Bank A keeps a photocopy of the agreement.
After 3 years, the borrower has repaid the loan. Bank A gets £5,000 back from the borrower plus £2,000 interest, meaning they make a profit of £2,000 on the deal. However, in addition, Bank A has also sold the piece of paper that the agreement is written on, adding another £5,000 profit to the deal.
In this parallel universe what's in it for Bank B? They buy the agreement from Bank A for £5000 and get what exactly in return?
I had to refer to it as "a bit of paper" in a final effort to get people like you and the chimp to separate it from the actual loan.
You may also wish to know that on the rare occasions that these agreements do resurface, they contain several stamps or endorsements, each one indicating that a transaction/sale has taken place.
The more informed on this forum readily accept that this trading takes place. I'm sorry if its not what you want to hear but hey-Worse things have happened at sea eh?
Think of it like a bond with face value. If I buy a $100 bond, I pay less for it, based on when it will pay out. I may be able to buy a $100 bond for $50, that will pay $100 in 7 years. However I only pay $50 for it. The bank selling it gets $50 today on a promise to pay $100 in 7 years. they can invest to $50 they get and hope to exceed the imputed interest, they may do better, or they may do worse, but you will get your $100 in 7 years, and they will get the benefit of $50 for 7 years. The difference in value is the interest.
My bond example is essentially what the purchasing bank is doing. They are buying the debt today at a reduced price, and effectively giving Bank A the PV of the note, at some interest rate, that leaves rome for margin on both sides. The purchasing bank only expects the original terms to be honored. To the debtor, nothing has changed, but for access to the loan. Without these securities, and the trading of debt, banks would stop lending, as they would have loaned out all their capital. Financial markets allow them to offload it today, and recognize income earlier, for a price.
One last thing, if it didn't make financial sense, a bank would not do it. Unless there is the potential of a profit, why would I bother with a transaction. It is also true, banks can be both buyers and sellers, but not everything is as it seems. They may be managing a risk matrix, and all $5k loans are not the same. Credit risk, current status, etc, may impact the loan. buying and selling instruments allows banks to rebalance risk and reqard.
