Unfortunately, forecasting inflation rates is about
as easy as forecasting the weather. And for primarily the same
reasons. When forecasting the weather there are a wide variety
of factors to consider and the same holds true for forecasting the
inflation rate. In its simplest terms
inflation is caused by an increase in the money supply. A
simple example is that of an island
with ten people on
it and each person has $1. and one item for sale. Simple mathematics
tells you the average price for each item would be $1.
Now suppose you
wanted to make everyone richer so you gave each one another dollar.
There are still only 10 items for sale but now there is $20 to spend
so the average price would now be $2 This means the price doubled,
so no one is any richer because they can still only buy one item
with their $2.
So it becomes
obvious that increasing the money supply will increase the inflation
rate. So one would think that simply tracking the money supply would
allow you to easily forecast the inflation rate. However,
there are a variety of definitions of "money supply" so forecasting
becomes more difficult. To make matters worse recently
the government stopped tracking the money supply see
Good-bye M3.
Forecasting is also made more difficult by the
fact that we have a world wide economy now.
The available money supply can be affected by a wide variety of
things from as far away as China. For instance our forecast
would be radically affected if China were to decide one day to dump
the billions of U.S. dollars it is currently holding as reserves.
Imagine
increasing the money supply of available dollars by a Billion
dollars overnight simply because China decided it would rather hold
Yen or Euros. In today's economy that is a distinct possibility.
Our Inflation
Rate Forecasting Method
Our inflation
rate forecasting method is different. Since 1997 we have been
using the Moore Inflation Predictor (MIP) to forecast the inflation
rate one year out. It has proved extremely accurate in
forecasting the twists and turns in inflation as calculated by the
most commonly used inflation index the CPI-U.
The Moore Inflation Predictor provides a technical
forecast of the inflation rate by month for the next 12 months.
We do this by combining elements of trend-following and reversion to
mean. We update the forecast chart monthly as new CPI
inflation data becomes available.
