But is the state of the US economy the right
indicator for the required monetary policy of the premier currency of the world
economy? Is, in other terms, a purely American debate the right framework for
analyzing the optimal supply of the main “vehicle” currency in world trade? Of
course a few other currencies are also used in international trade and as
reserve instruments, such as the euro and the Japanese yen. Monetary
authorities in control of both are currently implementing QE policies.
And as noted again by Bloomberg, JPMorgan Chase
& Co.’s average interest rate for eight developed nations and the euro-area
weighted by size is on course to end 2016 at just 0.36 percent. That’s a full 3
percentage points below the average of 2005 to 2007, which could mean that
expansive monetary policies are still implemented worldwide.
However, a slowing down of the dollar supply
could well affect negatively the world economy at a time when its overall
performance is lackluster, and almost zero or even negative inflation rates
generally prevail.
That said, are the fears of QE policies having been
somehow “excessive” before and after the 2008 crises, feeding “unsustainable”
asset bubbles all around the world that are waiting to burst, creating the
conditions for a devastating new financial crisis, warranted? And what about,
on the other hand, of the environment of “great stagnation” and insufficient
inflation worldwide?
A quick look at the evolution of both monetary
aggregates and trade growth rates in the world economy, as reported in the
table below, gives a different picture of a monetary expansion barely
sufficient to sustain the growth of world trade. If vindicated by more precise
study of data, that could be a factor in explaining the now long, post 2008, “great
stagnation” and such a hypothesis would warrant further quantitative easing by
the three main central banks for some time to come.
Aggregate Growth Rates
2005-2014 2008-2014
M1 (OECD total) + 193 % + 166 %
M3 (OECD
total) + 171 % + 135 %
M1 (Euro
Area) + 152 %
M3
(Euro Area) + 110 %
World Trade (Exports, Merchandises and
commercial services, WTO data)
1995-2014 2005-2014
+ 376 % + 183 %
The overall, although admittedly
impressionistic, conclusion that one can derive from these data is that
monetary expansion was just sufficient to sustain the growth of world trade,
and maybe insufficient post 2008.
The current need would thus be one of a
prolongation – rather than an interruption -- of QE policies, US included. It
could be that each central bank narrowly concentrating on the sole state of its
own economy, missed the overall picture of required increases in international
liquidity.
