Under current law, the Treasury is technically allowed to mint as many coins made of platinum as it wants and can assign them whatever value it pleases.

Under this scenario, the U.S. Mint would make a pair of trillion-dollar platinum coins. The president orders the coins to be deposited at the Federal Reserve. The Fed moves this money into Treasury’s accounts. And just like that, Treasury suddenly has an extra $2 trillion to pay off its obligations for the next two years — without needing to issue new debt. The ceiling is no longer an issue.
