The financial press reported last week that the value of the U.S. dollar plummeted
to a 14-year low against the British pound, and weakened against the Euro and
Yen. Many financial analysts predict continued rough times for the dollar in
2007, given reduced expectations for economic growth at home and less enthusiasm
among foreign central banks for holding U.S. debt.
This decline in the value of the dollar is simple to explain. The dollar loses
value as the direct result of the Federal Reserve and U.S. Treasury increasing
the money supply. Inflation, as the late Milton Friedman explained, is always
a monetary phenomenon. The federal government consistently wants to spend more
than it can tax and borrow, so Congress turns to the Fed for help in covering
the difference. The result is more dollars, both real and electronic-- which
means the value of every existing dollar goes down.
Federal Reserve Chairman Ben Bernanke faces two basic ongoing choices: raise
interest rates to prop up the dollar, but risk pushing the economy into a recession;
or lower interest rates to stimulate the economy, but risk further declines
in the dollar. This unfortunate dilemma is inherent with a fiat currency, however.
Of course Mr. Bernanke inherited this tightrope act from his predecessor Alan
Greenspan. The Federal Reserve did two things to artificially expand the economy
during the Greenspan era. First, it relentlessly lowered interest rates whenever
growth slowed. Interest rates should be set by the free market, with the availability
of savings determining the cost of borrowing money. In a healthy market economy,
more savings equals lower interest rates. When savings rates are low, capital
dries up and the cost of borrowing increases.
However, when the Fed sets interest rates artificially low, the cost of borrowing
becomes cheap. Individuals incur greater amounts of debt, while businesses
overextend themselves and grow without real gains in productivity. The bubble
bursts quickly once the credit dries up and the bills cannot be paid.
Second, the Fed steadily increased the monetary supply throughout the 1990s
by printing money. Recent Fed numbers show double-digit annual increases in
the M2 money supply. These new dollars may make Americans feel richer, but
the net result of monetary inflation has to be the devaluation of savings and
purchasing power.
The precipitous drop in the dollar shows how investors around the globe are
very concerned about American deficits and debt. When government policies in
a fiat system are the sole measure of a currency's worth, the currency
markets act as a reliable barometer of how those policies are viewed around
the world. Politicians often manage to fool voters and the media, but they
rarely fool the financial markets over time. When investors lack faith in the
U.S. dollar, they really lack faith in the economic policies of the U.S. government.
