Making mortgage rates predictions is a little
tricky. Financial markets, including those which set
share prices and mortgage interest rates, are chaotic
systems. This is not to say they are chaotic in the
common usage of the term, meaning something with no
order to it at all, but they are chaotic in the
mathematical sense, in that the formulas which describe
how mortgage interest rates are determined, which are
the formulas used to make mortgage rates predictions,
have self-referential components.
Making mortgage interest rates predictions is like
making weather predictions - it is impossible to be
precisely accurate with mortgage interest rates
predictions, and the further in advance you try to
predict mortgage interest rates, the greater the margin
of error in the prediction.
On the other hand, chaotic systems are predictable
in broad terms.
If you think about predicting the weather, you may
not be able to predict the top temperature for a given
day in August, but you can reasonably sure it will be
within a certain range - say, if you live in Orlando,
between 80 and 95 degrees F, and if you live in
Copenhagen, between 16 and 25 degrees C.
Just as climate gives a broad indicator of summer
top temperatures, economic climate gives a broad
indicator of mortgage interest rates.
Factors Which Make Mortgage Rates Rise:
Inflation
So called "real interest rates", the interest rates
which move in response to supply and demand in the
financial markets, are independent of inflation. To get
from the "real interest rate" to the "nominal interest
rate", which is what your bank will charge you for your
mortgage, you simply add on the annualised percentage
rate of inflation.
Factors Which Make Mortgage Rates Rise: Reduced
Availability Of Credit
Financial markets operate on supply and demand. If
there is a limited supply of anything, then it will go
to those who are willing or able to pay more for it.
The same is true of mortgage money. Mortgage rates
predictions will take into account whether the supply
of money is increasing or decreasing, and likewise, the
trends in demand for money.
Factors Which Make Mortgage Rates Predictions Rise:
Increased Risk
Apart from the underlying real interest rate
determined by the broader economy, the rate of
inflation, and the supply of money available for
mortgage lending, there is another factor which comes
into play in any investment decision - risk. Mortgage
rates in general will depend on the overall risk
involved in the housing market.
If house values plummet, as they have in some parts
of the US, then the default risk for the banks suddenly
increases, which means that they will be wanting to
charge higher mortgage interest rates; predictions will
take this upward pressure into account.
Factors Which Make Mortgage Rates Predictions Fall:
Government Intervention
The US Government is an 800-pound gorilla in the
financial markets. By issuing Treasury bonds at
different interest rates, the government can influence
the overall market for money, and thus affect the
"real" interest rate.
Mortgage rates predictions based on purely economic
considerations might indicate that mortgage interest
rates are due to rise, but while the political pressure
is running high, and in an election year, the
government will do everything in its power, however
economically irresponsible in the long term, to push
the interest rate rises off until after the November
elections. Mortgage rates predictions must take this
political distortion of the financial markets into
account.
