It's backed by the ability of the US government (and military) to ensure that the US is operating. As long as the US maintains a world hegemony, it's a safe bet. If it loses a series of engagements (not a single theater of economic interest), it's time to hop on to another currency. Ofc, that's just how I see it.
They all mostly do monetary policy the same way though.
Also, ss obviously is not the largest source of American's well being, and those other sources (wages) will not be keeping up with inflation.
stimulus checks were like few 100B, very different amount, total stimulus program was 2.2T: https://en.wikipedia.org/wiki/CARES_Act , while M1 supply increased from 4T to 20T: https://fred.stlouisfed.org/series/M1SL
I think institutions took advantage of low interest rates, borrowed lots of money, and now will borrow/invest with much higher return for next many years.
> That isn't the new rate of money supply growth
I don't think there was so large scaled increase in the past ever.
but does US maintain a world hegemony? How does it demonstrate hegemony?
Yes. As of today.
> How does it demonstrate hegemony?
As it has done since ww2. I mean, maybe that's a rhetorical philosophical question. I don't really care to argue about the self-evident history.
its totally not self-evident. Even after ww2 world was bi-polar, and now US leadership in economy and tech is much less evident.
When the average monthly expenses for an American household add up to about $5,500, certain industries (like transportation (16.8 percent of those expenses), or food (12.8 percent) will always view the American economy as a leading market to operate in. At a macro level, it would seem that many businesses making this similar judgement call would create a dynamic that goes beyond trust.
Regarding the buying power of pensions point, I believe there are cost of living adjustment laws for buying power which require Army or Social Security pensions to react to USD's changing buying power over time.
(There's no reason for government policy to eschew abundance, so I'm not particularly worried for the future, but that is because of the dynamics of the situation, not the laws that are in place)
the issue is that other currencies can be trusted even less.
