there’s no similar limit on the amount of coinage. A little-known statute gives the secretary of the Treasury the authority to issue platinum coins in any denomination. So some commentators have suggested that the Treasury create two $1 trillion coins, deposit them in its account in the Federal Reserve and write checks on the proceeds.

The government can also raise money through sales: For example, it could sell the Federal Reserve an option to purchase government property for $2 trillion. The Fed would then credit the proceeds to the government’s checking account. Once Congress lifts the debt ceiling, the president could buy back the option for a dollar, or the option could simply expire in 90 days.

I hate the idea, but only slightly less than the idea of having to do this again in six months.
