Something tells me Krugman would not have endorsed such an absurd idea back when Obama was voting against raising the debt ceiling during the Bush administration.
Coins Against Crazies — Paul Krugman, NYT
So, have you heard the one about the trillion-dollar coin? It may sound like a joke. But if we aren’t ready to mint that coin or take some equivalent action, the joke will be on us — and a very sick joke it will be, too. […]
As it happens, an obscure legal clause grants the secretary of the Treasury the right to mint and issue platinum coins in any quantity or denomination he chooses. Such coins were, of course, intended to be collectors’ items, struck to commemorate special occasions. But the law is the law — and it offers a simple if strange way out of the crisis.
Here’s how it would work: The Treasury would mint a platinum coin with a face value of $1 trillion (or many coins with smaller values; it doesn’t really matter). This coin would immediately be deposited at the Federal Reserve, which would credit the sum to the government’s account. And the government could then write checks against that account, continuing normal operations without issuing new debt.
In case you’re wondering, no, this wouldn’t be an inflationary exercise in printing money. Aside from the fact that printing money isn’t inflationary under current conditions, the Fed could and would offset the Treasury’s cash withdrawals by selling other assets or borrowing more from banks, so that in reality the U.S. government as a whole (which includes the Fed) would continue to engage in normal borrowing. Basically, this would just be an accounting trick, but that’s a good thing. The debt ceiling is a case of accounting nonsense gone malignant; using an accounting trick to negate it is entirely appropriate.
But wouldn’t the coin trick be undignified? Yes, it would — but better to look slightly silly than to let a financial and Constitutional crisis explode.
