Are there other ways for the president to raise money besides borrowing?
Sovereign governments such as the United States can print new money. However, there's a statutory limit to the amount of paper currency that can be in circulation at any one time.
Ironically, 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. And there are probably other ways that the Fed could achieve a similar result, by analogy to its actions during the 2008 financial crisis, when it made huge loans and purchases to bail out the financial sector.(snip)
