The Zimbabwean dollar is not the world's reserve currency. Zimbabwe cannot park a naval fleet off the coast of any country that tries to move away from the Zimbabwean dollar, or direct the worlds largest banks to freeze assets, or apply crushing economic sanctions.
The US is probably the only country in the world that can print money without runaway inflation, and I don't doubt that we will maintain dollar hegemony with force if needed.
Once you satisfy all that, high inflation just means you’re either spending too much, or not taxing enough.
A big part of what happened in Zimbabwe, by the way, was that land reforms caused a massive collapse in food production (a major part of their economy) and unemployment skyrocketed. They spent a lot in response (also having foreign denominated debt I believe), but mostly not focused on policy that would increase capacity. At the same time, they were having to spend much of their foreign reserves on food because of the supply collapse. So the spending and hyperinflation were inevitably consequences of previous mismanagement.
Okay.
Fed officials are predicting 30% unemployment, and we're seeing a massive collapse in goods and services production (not food, but it may as well be in a 70% services based economy) as cities go into lockdown. To respond to this, we intend to spend a lot.
I'm a bit confused as to how the current situation doesn't mirror, nearly perfectly, the Zimbabwe example. We are literally printing and spending into a severe supply (yes, services follow supply curves just as much as goods do) and unemployment shock.
I'm not an economist but as far as I understand these things we won't get hyperinflation as long as there is confidence in the dollar as a currency.
