How are 30 year fixed mortgage rates calculated?

The Federal Reserve and the bond market play a big part in how the economy works and how interest rates are determined. Many numbers and indices go in to the caluculations and many things affect the rate like Economic indicators, Job stability, bond rates, treasury bills, the stock market, etc. just to name a few, it is a complex calculation. Banks then sell their money based on what the buyers on Wall Street will purchase mortgage backed securities at.

I do not think there is any one place that can tell you all of this but you could try and look on the internet and the information that you ascertain will only be good for that moment in time as it is an ever flucuation calculation. The bottom line is the rates are what they are on the day they are issued, the are in a constant state of flux with some times being more volatile than others. The movement of the rates helps control the economy by speeding it up or slowing it down. The mortgage industry is in a huge state of turmoil right now with all the information in the news, etc. One thing you can always count on is that rates might go up and rates might go down. Locking into an interest rate is a risk, rates might go down, floating an interest rate is a risk, rates might go up. You never know.
