Is Fed getting into the business of making money?

http://www.nytimes.com/2011/01/11/business/economy/11treasury.html?ref=businessThe following news caught my attention:
"The Federal Reserve will deliver a record $78.4 billion to the Treasury from its investments last year, a 65 percent increase from the $47.4 billion it transferred in 2009, according to preliminary estimates released Monday. "
So I was wondering from where the profit is coming and I found the biggest arbitrage business of the world! Fed is a big hedge fund and has found a great arbitrage opportunity in name of saving US.


The bank reserves with Fed have balloned over last two years!
* In 2008 Fed/US Government started paying interest (@ fed funds rate - 10 bp) on Bank Reserves with Fed so the reserves ballooned from 40b to 1,040 billions.
* Besides the temptation of earning interest,  other reason behind this jump is the hesitation by US banks in lending/investing this money themselves. You, I and everyone has money in bank accounts which earn almost nothing. It seems that the banks are not lending this money to anyone either or they are not investing in mortgage or other higher interest instruments. Instead, seems like, banks are keeping these extra fund on demand deposits (I mean Reserves) with Fed.
See the following table that shows the jump in Reserves with Fed.

Fed announced few months back that they would be buying additional 600b dollars worth of mortgages. This is where yours, mine and everyone's money in our bank accounts is going. We are aware or we are not, but our money is used to hold our own mortages!
Think of this situation: Your money in bank accounts earn no interest but you are probably paying 5-7% interest on home mortgage. Fed is exactly in the opposite- they have money that costs very little but they are earning interests in the range of 4-6% by investing in out mortgages!
* Fed now invests this money in Mortgage and Treasury bonds repurchase (earning 4% to 6%)- earning net 50 billion dollars!!

This arbitrage may not be the main objective of Fed, but I am sure, Fed, Treasure and deficit-ridden US goverment would be loving this nice cashflow of 50 plus billions.

What is the cost here?
1) If banks start withdrawing this excess reserve, Fed will have to sell the bonds (causing rates to go up sharply) or print money. If they start selling these bonds, the bond prices will tend to fall. Lower bond prices mean higher interest rates. Higher rates in the economy--- lower economical growth.

See some notes, taken from an article on NYTimes:
Interest income from its investment portfolio has produced record profits for the Fed for two consecutive years. But over time, when economic conditions improve, the portfolio could become a risk, because the investments could lose value when interest rates eventually rise.


“From the taxpayers’ view, I think it is a mistake to make much of this number either way,” said John H. Cochrane, an economist who has been critical of the central bank. “The Fed is acting like a huge hedge fund on our behalf. It is borrowing at very low short-term rates and investing in long-term government bonds, mortgages and other risky loans. It made a profit on those investments last year, but it is bearing a lot of risk.”

Mr. Cochrane, a University of Chicago finance professor, said the Fed was intentionally bearing those risks to support housing and other markets.

“But inevitably, with a big portfolio of long-term bonds, mortgages and risky securities, the day will come when the Fed loses money on those investments, at least on a mark-to-market basis,” Mr. Cochrane added, referring to the accounting the Fed uses to fairly value its balance sheet.


2) If Fed does not want to sell the bonds, they will probably have to resort to print money to pay back those reserves.

3) Money spoils everyone. Though the Fed is entrusted with non-profit motives, it is very likely that their motives may be biased now. Directly or indirectly, the profit will keep coming in their economical decisions. Washington will also hate to lose this billions of dollars....so in the name of keeping the US vibrant, loweing unemployment, they would like to keep the game going...

4) We blamed Greenspan for causing housing bubble by keeping interest rates artificially lower... Current game is even bigger! The rates are artificially lower for long time...coupled with many benefits to troubled home-owners. If the home prices have to start booming, there will be even more players in the next housing boom because Real Estate investment now comes with a free Put option! If you get in losses, government is always there to bail you out! If you have profit in your real estate investments, it is yours to keep! Very advantageous proposition for investing in Real Estate compared to trading stocks or putting money in Cisco or Citibank!
