The total economic activity of a country is
referred to as its Gross Domestic Product (GDP). Aggregating the
annual GDP for each country yields
total
world economic activity,
which is usually referred to as Gross World Product (GWP). When the economy
of an individual country experiences a
contraction, a period when GDP actually declines, it is called a
recession. Since the tracking
of total world economic output began,
there has never been a year in which GWP declined. GWP grows at an
average rate of about 3.5% annually. Since GWP has never
been negative, a global
recession is generally defined by economists as GWP
dropping below a 2 - 2.5% annual growth rate for one or more years.
When
oil prices rise rapidly or supply interruptions occur, as has happened
several
times since 1971, the U.S. economy usually
falls into a
recession
within a fairly short period of time. Just as the U.S. economy is
directly tied to a steady supply of cheap
imported oil, the world economy also requires oil price and supply
stability in order to maintain economic growth trends. The global
economy falters during oil shocks and it is not a coincidence that the
four times since 1971 a global recession has occurred it was preceded
by a
rapid rise in the price of crude oil. Because of the diverse
nature of economies around the world, it often
takes a year or more before the full impact of an oil price shock
takes
effect and slows GWP growth sufficiently to cause a
world oil
recession.
The 1973 Arab
oil embargo
caused
the first world oil recession, which began in 1974 and lasted for two
years. In less than a year,
limited supplies and OPEC price increases caused oil prices to quadruple, rising
from about $3 a barrel to
over $12 a barrel. It was a relatively mild global recession with
GWP growth barely dropping below 1.5% in 1975 and quickly recovering in
1976 as oil prices remained fairly stable and economies around the world adjusted
to the new price levels.
The second global oil recession began in 1980, again after crude oil
prices rose rapidly. The initial oil price spike was due to
a decrease in supply caused by the
Iranian
revolution.
Oil prices rose from below $15 a
barrel in January of 1979 to over $30 a barrel in January of 1980 and
then to over $38 a barrel in February of 1981 after the onset of the
Iran-Iraq
war. It was by far the
most severe global recession, with growth slowing to 2% in 1980 and
falling below 1% in 1982. The
recession lasted for three years and ended after oil prices stabilized
and then began to fall in 1982 and 1983 in response to significantly reduced
worldwide
demand.
The third world oil recession began in 1991 and lasted for three
years. It too started after oil supply disruptions and rapid
price increases, this time caused by
Iraq's
invasion
and subsequent occupation of Kuwait.
Oil prices fluctuated between about $12 and $20 a barrel throughout
1988 and 1989, which decreased GWP growth to under 3% in 1990 after
several years of above average growth. Oil prices increased from
under $15 a barrel in June of 1990 to over $31 a
barrel in September of 1990. Even though prices fell back to
under $20 by February of 1991, the damage was already done and GWP
growth fell to 1.5% in 1991 and only rose to 2% during 1992 and
1993. Average GWP growth returned in 1994 after oil prices
dropped from about $20 a barrel in 1992 to about $12 a barrel in 1993.
A
fourth global oil recession started in 2001 and only lasted one
year. It was by far the mildest global recession with GWP growth
not even falling to 2% after oil
prices rapidly rose from under $10 a barrel in January of 1999 to over
$30 in September of
2000. Tight supplies
caused by OPEC production cutbacks intended to increase
prices were the cause of the oil price increase. GWP growth
quickly rose to above average levels in 2003 after oil prices dropped
back to about $15 a barrel in 2001.
By all rights, another world oil recession
probably should have started in 2007 or 2008, after the
slow
and steady increase
in oil prices from under $20 a barrel in 2002 to nearly $70 a barrel in
2006. Part of the reason GWP grew at well above average rates
from 2004 to 2007, even in the face of rising oil prices, was that
prices did not rise too rapidly and gave economies around the world
more of a chance to adjust. However, the main reason was that
developing countries, especially
India and China, and oil exporting countries experienced unprecedented
economic growth during that time. That
unprecedented growth was fueled by massive transfers of wealth from
Western countries that were experiencing asset bubbles in housing,
commodity, and stock markets purchasing imports. Those asset
bubbles have all now burst and demand for imports has declined significantly.
The fifth world oil recession will almost certainly
begin in 2009, though it is possible that sheer momentum will be able
to keep GWP growth above 2.5% and delay the start until 2010. The
severe damage inflicted on economies around the
globe by the huge
oil price shock
experienced in 2007 and 2008 helped to cause the asset bubbles that had
been feeding demand for exports from developing countries to burst rather
than slowly deflate as they might have under normal
circumstances. Without those asset bubbles to support imports of
their products, developing countries will no longer be able to sustain
the high economic growth rates they had been enjoying and GWP growth
will fall dramatically. Another global oil recession is assured;
the only unknowns are when it will start, how severe it will be, and
how long it will last.
