Returning from a conference in Mexico, I witnessed an
unusual scene. An American at Cabos airport was
attempting to pay for his drinks with a British 20-pound
note. The barman was polite, but refused. Mexican pesos
were acceptable (this was, after all, Mexico). American
dollars were acceptable. But the British pound was not.
The
British pound has limited acceptability outside of the
British Isles. However, this was not always the case. A
century ago, the British pound was the only currency
worth having for international transactions: it was the
world’s reserve currency. However, by 1948 the dollar
had effectively replaced sterling as the global reserve
currency. Now the reserve status of the dollar is in
question.
What is
a reserve currency? Most people think of reserve status
as relating to the official, central-bank managed
foreign-exchange reserves of countries. Of course, the
foreign-exchange reserves of Asia have grown
substantially in size. Around two-thirds of the world’s
official foreign-exchange reserves are held in dollars—a
level that has been fairly constant over time.
However,
official foreign-exchange reserves are not the most
important reserve. The private sector also needs
foreign-exchange reserves to conduct international
trade.
In 1970
a Philippine importer, wishing to purchase goods from a
Japanese exporter, would have had to have conducted that
transaction in dollars. This meant that the Philippine
importer would have had to have access to dollars, and
the Japanese exporter would have (briefly) received
dollars. There was a reason for both sides to hold a
certain amount of dollar cash, to facilitate business
transactions.
In the
last few years, the private-sector role for the dollar
has been in decline. The private sector is increasingly
looking to other currencies. In fact, a Philippine
importer seeking to do business with a Japanese company
today is far more likely to have to pay yen. Over half
of Japan’s exports to Asia are invoiced in yen.
Does it
matter whether one is paying yen or dollars for the
imports?
Reserve
status matters in three ways: it matters to the US
economy; it matters to the value of the dollar; and it
matters to importers and exporters in the Philippine
economy.
The US
receives a benefit from being the world’s reserve
currency. Basically, foreign-exchange reserves are an
interest-free loan—a means of financing the US
current-account deficit “for free.” At the moment, the
dollar’s reserve currency status is worth around $31
billion a year to the
US
economy. As the reserve status of the dollar diminishes,
this economic benefit to the US economy will diminish.
Related
to this, the dollar’s value receives support from its
reserve status. Assuming that the value of global trade
grows each year, there is a “natural” demand for dollars
to fund that international trade. If the dollar’s
reserve status continues to be undermined, the “natural”
demand for dollars will decline and a support for the
dollar’s value will also diminish.
For
Philippine importers and exporters, the decline of the
dollar’s reserve status is complex and depends on the
position of the Philippine company. If the company is
the dominant partner in the transaction, then they will
be able to demand that invoices are in Philippine peso.
That means that the Philippine company carries no
foreign exchange risk.
Clearly,
this is a benefit. However, if the Philippine company is
not able to dictate the terms of the contract, then they
will have to hold reserves in whatever currency their
counterpart wishes to deal in—yen, euros, dollars or
even pounds sterling. Because they will end up holding
reserves in more than one currency, the cost will
increase.
The
dollar’s decline as a reserve currency is likely to be
drawn out. However the growth in private-sector use of
the other currencies in international transactions means
that Philippine firms (and maybe even the Philippine
central bank) may need to reconsider the currencies that
they hold.
As for
the American tourist in Mexico, as a British subject I
was only too happy to purchase his pounds from him. As
an economist I reflect the balance of global reserves,
and I always carry dollars, euros, Swiss francs and
pounds sterling in my wallet.
