It's time to stop talking about "debt" as if it's actually any sort of debt, it's not. What we refer to as "US debt" is actually just money supply. When US "debt" is held by private individuals, it's just our savings. When its held by foreign governments, it's no different than holding cash.
Look at Japan, who has "purchased" their debt by printing money. These financial instruments are completely fungible. And it's fundamentally not "debt" because the US can *never* involuntarily default on the debt. And if the US did decide to default on some it's "debt," it would only be like burning some cash of the T-bill holder, instead of printing money to back it.
Foreign governments are gobbling up T-bills at *negative* interest rates. That's because more people want to be able to exchange things in dollars, and the T-bills are preferred to holding cash. We could also just print dollars, and get them out in circulation through government spending, or by buying back existing T-bills with those dollars.
Calling this stuff "debt" is just deceptive, and leads to bad policy. We need to start calling it "money supply." Our "debt" is really just printing money, with the side effect of the government setting the minimum borrowing rate that banks will borrow at. T-bills are just dollar bills with interest side effects.
> We need the top minds working on this now, not waiting until after disaster strikes and then analyzing it after the fact!
This sounds a lot like longtermist effective altruists' calls to work on reducing existential risks now, since we *cannot* wait until an "existential" disaster (either extinction or an equally bad outcome like the permanent collapse of civilization) destroys our whole future to start preventing it.
Inflation (and especially hyperinflation) is caused by spending beyond the productive capacity of the economy. It really only turns hyper if the government starts printing money but any excessive spending beyond capacity can trigger it.
Oh, and congratulations on excepting the core arguments of MMT. Kelton's response when people ask her this question is along the lines of 'Good question! that is what economists should be trying to calculate how much spare productive capacity we have, rather than trying to worry about irrelevant numbers.'
Let macroeconomists and economic historians do the work, but why not turn microeconomists off microfounded macro and onto the work of informing Congress and Fed which markets are tight and which slack or elastic so that inflationary spending can be avoided.
I like that you attempt to wrestle with this question.
However, I find that right at the beginning of your logical train of thought you're immediately making an unfounded assumption: "If the U.S. federal government keeps borrowing and borrowing and borrowing without limit, eventually foreigners and private companies and citizens are not going to want to buy all of those Treasuries."
Why would this be true?
Consider this: If the government keeps borrowing and borrowing, then presumably they will also spend as much money as they borrow (there's a somewhat silly hypothetical where they keep borrowing and borrowing but don't spend any money -- but that seems overly silly even for the US political system, so let's ignore it!).
This means money gets into the hands of people, and more importantly, central bank money is moved onto the balance sheets of banks. The banks will want to get rid of this central bank money if possible since it doesn't bear interest, so buying treasury bonds with a non-zero interest rate will always be profitable for the banks. Which seems to imply that banks will always be willing to buy treasury bonds, which is the same as saying that the US federal government will always find borrowers.
No?
If not, then perhaps that's the very first thing that needs to be answered, before or at least in tandem with the other points you make.
There's an interesting question of: if this apply to the US, why doesn't it (seem to) apply to other countries. However, it might actually apply to all countries, at least to all that issue their own currency, and only borrow in it (i.e., what some people call monetarily sovereign).
"we are not going to be able to formulate proper safeguards against government over-borrowing based on one IMF working paper that precisely 0.7 people will ever read"
At least two people have read this now, Noah. Thanks for sharing.
what's important in money velocity, which is related to inflation expectations. As long as people accumulate the paper money there is little inflation. Once they realise that the quicker they spend the money the better for them, inflation starts accelerating rapidly
The US$ may never hyperinflate because we all love dollars way too much. Much more than the actual stuff we can buy with them. That's why FED QE is going exponential, to keep up with us.
If inflation is triggered when the value of money exceeds the productive capacity of the economy then what impact does all advanced economies synchronously increasing debt and money supply have. If all currencies are devalued together then surely no one ends up devaluing in international trade.
I imagine social trust is a major factor. Japan is famously high-trust, while the sort of regime changes identified in the IMF paper would presumably have caused distrust in the government. After all, the economy is just a bunch of people having certain expectations of each other. Now, what is the level of trust going to be in the US going forward...
Thanks Noah. I've been raising this point lately with my own little voice. Policy-wise, the Democrats need a pragmatic economic answer to this question and politically, they need a pithy distillation of that answer. The deficit is clearly going to be a major point of Republican attack in 2022 and the Dems can't go intellectually and rhetorically defenseless against it.
Whether money is minted or printed or computer bits flipped, "maximizing revenue from seignorage" seems relevant because the constraint is the same, the real economy.
Inflation is caused by a shortage of resources, not an excess of money. As long as you have a sovereign currency, and DON"T borrow from other countries (like Venezuela did) and as long as you carefully target your spending (it's called management) the economy will expand to the benefit of all.
Ray Dalio has been spending a lot of time thinking and writing about this. While not a trained macro-economist, he does have access to them and he is obviously an expert in financial markets. I also think the popularity of Cryptocurrencies indicates more and more younger folks are, in fact, quite worried about this question while older folks, like me, have spent their formative years in the Volker era when we assume inflation won't be an issue. Point being, it might be harder for governments to push the envelope than it has been. Certainly hope the next generation is smarter than mine.

Here's one paper on maximum seignorage/hyperinflation, maybe others in the cites are also relevant https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3141272
