Federal Bank or Fed (like RBI in India) last week did helped one of the top investment banks (Bear Sterns) going out of business; Bear Sterns was funded around 200 Billion USD to remain in business by Fed in terms of collateral as Bonds.
Why on a Sunday night, Fed Chairman Ben Bernanke came out immediately in the moment when Bear's were losing shareholders or investors, which is anyway a stock trading investment bank - not our savings account or checking account money held in commercial bank or government money going down. Why did Fed did that inspite of Protestors who lost homes did charged Bear's office last week? Fed could have helped them by giving the money to people? 200 Billion could bring these people out of debt..
Do you know the rippling effect which happens when a stone is thrown in the pond.What is this connected to Fed & Bear. Let me explain.
Say if you are a small town, you have few banks, few business (lets take a food store) in the town runs by borrowing money from the bank (You asking why?, lets take an example, if you want rice you go to a shop and buy. But does the farmer have to wait till he gets an order, then plants rice and then gives you, NO. He borrows from a bank, puts that money into land as seeds and then after harvest, wait for profit - Once he gets money, he pays the bank and makes some profit).. You as a customer to these businesses rent a house, use electricity and buy food etc.
Lets say some day banks don't have money to lend or simply they don't lend any further to business or any new business. What happens. Business cant run because they need money to run. So the Mayor of the town will have to import from other cities to feed you. So the money of the town is spend as expense to buy rice or commodities from other towns. If that is the case, think about you buying rice from farmers market and from a super market store. The rice in the super market store might have come from china too :).. so the price is going to be = Price of rice (that may be cheap) but + transportation cost + inventory cost + import duty cost .etc....
Now think about USA... if banks in USA loose money or they run out of business, huge industries in USA would get huge hit and inflation will peak. (This Bear thing did happen in India, you guys should remember. Chit Funds, when few chit funds cheated and the news spread, many people raided other chit funds. So even good performing chit funds would have got hit when people asked their money back.)
My point is, may be only to avoid this, Fed did back up Bear so that, if Bear falls, it may send a false hope across investors - many would pull their money - other investment banks might get affected. This is called Credit-Crunch in financial market, where no one is ready to use their money for anything. And this causes a state, in short named as,DEPRESSION. As in 1929.
