Inflation is
back in the news. While there are a few folks worried about rising inflation
much of the energy has been focused on it falling (often called disinflation). The latest news on
inflation in April showed it negative, -0.4% in April after -0.2% in March (a
negative inflation rate means prices are falling and is often called deflation). Consumers generally like
inflation to fall, so this is good news for them. It was also cheered by asset
holders because lower inflation means the Fed has more room to pump up the
economy. Of course, if disinflation or deflation continues, many will take this
as a sign that the economy is once again going into a recession. And that is
not good news.
So here we
are. As usual we have a difference of opinion. Some experts are worried about
the inflation rate rising while others are worried it is going to fall. While
the past is never a perfect guide for tomorrow, it doesn’t hurt to review what
the data shows us. And what the data shows is disconcerting. While inflation
may well fall more in the near future there is every reason to bet it will come
back with a vengeance. This data came from Fred at the St. Louis Fed. Fred is a
handy-dandy free data and graph service. http://research.stlouisfed.org/fred2/
The graph
below plots annual values of two measures of US inflation from 1959 to present.
One measure is based on the well-known Consumer Price Index for All Urban
Consumers. The second one is drawn from the less-well-known Personal
Consumption Expenditures Deflator Excluding Food and Energy. Inflation rates
are created by taking annual percentage changes in these indexes. Because these
index names are long and ugly I am going to called them Steve (blue line in the chart) (like in Steve Martin who is wild and Crazy) and Angela (red line in the chart) (as in Angela Merkel who is not
wild and crazy).
Steve
inflation is published by the US Labor Department and is based on surveys of
prices paid by the typical urban consumer. Steve inflation often swings wildly
because food and energy are important parts of Steve and these prices can
gyrate like Britney Spears after a night on the town. For example the graph
shows Steve inflation rising to about 14% in 1979 only to fall back to about 3%
within a few years. Much of that was attributed to food and energy. Not that food
and energy prices don’t affect consumers – but they do distort what is
happening to the prices of what most of the consumers buy.
That is why I added
Angela inflation – she is constructed and published by the US Commerce
Department as a tool to deflate personal consumer spending. Angela is a little
more boring because the Commerce Department has removed those pesky food and
energy prices from this version of the PCE deflator. (This index also makes an
attempt to remove some of the bias caused by Steve’s assumption that people do
not economize on goods and services whose prices are rising the fastest.)
So that’s
Steve inflation and Angela inflation. A quick look at the chart shows that
Steve swings around like a young lady at a ho-down in Arkansas. Angela is more
conservative and I must conclude – much more refined and reliable. Some might
say that Angela is smoother! But notice too that Angela and Steve have the same
general tendencies or trends. So while they might disagree on the extent of
inflation during a particular year or two – they both agree on the general
direction of inflation. Notice that from 1959 to 1979 they both were rising and
thereafter falling. You might say that the most current trend of inflation was to
flatten at a little less than 2.5% starting in about 1990.
Apparently
what goes up must come down. As we think about where we are today and what will
come tomorrow it is good to see these trends. But they are only part of the
story. For example, you might want to extend the downward trend since 1979 into
the future. That would argue against a quick return to higher inflation. Then
again, you might think that 15 years of falling inflation is long enough for
the trend and therefore you might want to predict a reversal of trend. In that
case you are worried about rising inflation.
There is
more to see in this graph. Notice the vertical shaded areas – they depict recessions.
We have had eight recessions since 1959. After seven of those eight recessions
the inflation rate fell. That makes economic sense. Recessions are times when
buyers slow their purchases and firms find it more difficult to sell goods.
They often discount their prices to get rid of excess inventories. These disinflation
periods following recessions can be very shallow and short (e.g. after the 1970
recession) or they can be much longer and more pronounced (e.g. after the 1980
recession). After the 1990 recession the inflation rate fell for almost 10
years.
Now look at
inflation behavior before each recession. In all the recessions except
for 1982, the inflation rate was rising before the recession started. In all
those cases you had sharp changes in Fed policy – increasing interest rates to
try to cool off the inflationary economy. But as soon as the recession was
evident, the Fed reversed engines and reduced interest rates. In one sense the
policies worked – you can see that inflation did fall. But the unintended
consequence of the tight money policy was a recession.
So what do
we have? We have inflation rising followed by tight money followed by inflation
falling followed by loose money followed by rising inflation. This cycle goes on and on. The prudent thing
would be to bring monetary policy back to neutrality once the worst of the
recession is over. Why? To answer that question we have to look into what caused the pesky inflation to begin with. The graph shows that food and energy
prices must have had some impact driving overall inflation upwards – especially
in the 1970s. But food and energy prices do not explain the upward thrust of
inflation that occurred in in the late 1980s, late 1990s, and then again after
the turn of the century.
Fed policy
had very much to do with driving inflation periods higher after those recessions.
This belief is based on policy data. I used the level of the federal funds rate
(ffr) as my measure of monetary policy. When the Fed wants to tighten policy
they raise their goal for ffr; when they want to loosen money they reduce the
ffr. So here is what I found:
·
The 1982 recession ended in November 1982. The ffr went from 15.1% in early 1981 to 6.6% in
March of 1988. In other words – the Fed kept monetary policy very loose more
than six years after the end of the recession.
·
The 1990/91 recession ended in March of 1991. The first quarter of 1989 had a ffr of 9.8%. It
was reduced until February of 1994 to the point where it was 3.3%. Again the
ffr was kept very low until three years after the end of the recession.
·
The 2001 recession ended in November of that year. The ffr was about 6.5% at the end of
2000 and continued down to 1.8% until November of 2004 – three years
after the end of the recession.
·
Finally
the 2008/2009 recession ended in June of 2009. The ffr started at 5.3%
in mid-2007. It started down and has remained at 0.25% as of today. Today is
now four years after the recession. It is unclear when the Fed will
again begin the raise rates.
What is the
history lesson? The Fed is an aggressive agent for monetary policy. It strikes hard
at rising inflation and tries to offset recessions. But it also has a tendency
to be very late when it comes to withdrawing monetary stimulus after recessions end. After the last
four recessions, the Fed was late when it came to leaving the dance. They left
four years late! They
are still dancing some four years after the last recession.
Why not stay
at the dance? The answer is in the data. Monetary policy eventually revs up the
economic engine. Recessions do not last forever and the economy returns to
strength. Always worried they didn’t do enough, the Fed keeps the stimulus
going for too long and the result is – higher inflation and then a need to
fight inflation again. And then another recession.
To my
scientific friends – I know a graph or two does not constitute real scientific
proof of anything. Someone else might be able to manipulate data that shows a
fuzzier result. But I have been reading the literature and watching the economy
for decades. I don’t think you can deny the fact that the Fed can best be
described by the old adage -- from the frying pan into the fire and back again.
It is time for the fed to reduce monetary stimulus and forestall the usual
recession-inflation-recession nightmare.
