The Democrats want to continue spending the US dollar into worthlessness. The Republicans are trying to get some budget cuts in exchange, but Biden is saying his way, or default. He is laying the blame on Republicans because he is refusing to budge. The solution, some on the left are saying, is to mint a $1 trillion coin, and deposit it with the Fed.
The idea is to mint a worthless coin that has face value of $1 trillion. That way, the coin has one trillion dollars of seigniorage, i.e. profit for government, and the coin could be deposited to Federal Reserve treasury instead of issuing debt. In other words, they would be issuing new money by debasing the dollar, without generating debt in their balance sheet. It’s like issuing one trillion worth of cash, which is backed with just one worthless platinum coin. It’s not really different from just issuing debt that isn’t paid back, but this way they don’t have to raise the debt limit. This would instantly insert an additional trillion into circulation, creating a massive amount of inflation. Shenanigans like this will completely erode the trust in the value of dollar and make the dollar worth much less nearly overnight. It’s like writing a worthless check to pay your monthly mortgage payment.
This will allow Biden to continue spending money like the dollar is going out of style, which of course it is. God forbid we should actually learn to live within our means.
