“[...] the US government’s dollar position is short, not long — its dollar-denominated debts are greater than its dollar-denominated assets. In financial terms, a short position is a way to bet against the value of the underlying commodity. The US government is currently about $7 million million dollars “short”.
An illustration may help to clarify. Suppose you are a private in the Zimbabwean military in September 2007. Suppose your monthly pay is about US$180, but you are paid in Zimbabwean dollars, so your pay packet is actually Z$5.4 million for the month. The Zimbabwean dollar has been hyperinflating, and you expect it to continue to lose value. You don’t currently need to pay any expenses. Consider the following options:
A. Keep the Z$5.4 million in cash.
B. Immediately buy other commodities with it; for example, buy 300 kilograms of rice and store it in Tupperware in the pantry.
C. Immediately buy other commodities with it, and also borrow an additional Z$10 million some poor sucker is willing to lend you at an extortionate 20% APR, and use that to buy rice too.
Option “A” is maintaining a “long” position in the Zimbabwean dollar. This amounts to a bet that the Z$ will retain its value. If you had taken this option, you would have lost 90% of your salary within a few weeks.
Option “B” is maintaining no position in the Zimbabwean dollar. It doesn’t matter what the Zimbabwean dollar does thereafter; you still have the same amount of rice. (Practically speaking, in situations like this, there tend to be price controls on most things you can buy with the collapsing currency.)
Option “C” is maintaining a “short” position in the Zimbabwean dollar. If you had somehow found such a sucker, then within a few weeks, you could have paid them back by selling off a tiny percentage of the rice you bought, as the Zimbabwean dollar continued to inflate.
This is the position the US government has taken relative to the US dollar.”
