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.

Now, the platinum coin may not be the only option. Maybe the president can simply declare that as he understands the Constitution, his duty to carry out Congressional mandates on taxes and spending takes priority over the debt ceiling. Or he might be able to finance government operations by issuing coupons that look like debt and act like debt but that, he insists, aren’t debt and, therefore, don’t count against the ceiling.
