Debt ceiling

Paul Krugman has big ideas about the manufactured debt ceiling crisis and shares them on Twitter:

About possible end runs around the debt ceiling. I have no inside information, but my guess is that premium bonds are a more likely route than the platinum coin. Why? Because nobody understands premium bonds, while people think — wrongly — that they understand the coin. 1/
Premium bonds: a bond has a principal or face value, which is what is paid when it matures, and a coupon that is paid every year until then. The idea is to issue bonds with, say, a $1000 principal and a $100 annual coupon. 2/
Since market interest rates are way below 10%, such a bond could be auctioned off for much more than $1000 — but Treasury could say that if the bond replaces an existing $1000 bond, it hasn’t increased the debt even though it’s raising a lot of money. 3/

Extreme example would be consols, which are just a perpetual coupon with no principal. In my experience, if you try to explain all this, people’s eyes glaze over — which is good! Hard to get outraged over something that baffles you. 4/

The coin: Treasury exploits a quirk that permits minting of platinum coins in any denomination to mint a coin with a face value of $1 trillion, deposits it at the Fed, then uses funds from that bank account to pay bills. 5/
Think of the Fed as a branch of the federal government, which from a fiscal point of view it is. Then this consolidated entity would in effect be covering deficits by selling bonds — i.e., normal deficit finance, just through the back door. 7/
