What Will the Fed Do Now That Rates Are at Zero?

Buying properties doesn't bring mortage rates down. Objectively mortgage rates are based off of libor. Generally banks base it off the 10 yr libor and add 200 basis pts or use an average of the 10 year treasury plus 200 basis pts. What creates the libor rate is demand and supply for loanable funds. When the securitization market seized up in sep and october, the supply of loanable funds sharply decreased forcing the cost of borrowing up. Demand also fell but not at the same rate as supply. The avg mortgage rate in sep was 6.04 in Oct it jumped to 6.2. After the Fed made a commitment to purchase MBS from Fannie and Freddie in late October/early Nov. the liquidity "expectations" reemerged dropping rates to its current level.

The Fed funds rate can influence the mortgage rate during healthy times,but during times of financial crisis they don't normally follow as closely. For example, during the last recessin the fed brought the discount rate down, but the mortgage rates didn't reflect this added stimulus.

The Fed is attempting to restore confidence back into the MBS market. They are literally planning on doing this by buying MBS. As you know there is an inverse correlation between bond prices and yields so when the Fed buys MBSs it increases the bond price and lowers the yield on these MBS. The lower yield helps increase confidence and liquidity in the loanable funds market.

With all this said, you can lead a horse to water, but you can't make it drink. On both the consumer and business side, no matter how cheap the cost of money gets, people still need to take risks and not enough people are willing to do this.
