Earlier quoted context omitted.
Agree the Russian invasion doesn't help matters... but this is not the primary cause of inflation. The amount of money that the US has simply created and spent in last couple of years in unprecedented. The amount of money inserted into the US economy dwarfs that of the TARPP and related bailouts of 2008 by a factor of 4. You just cannot create and hand out that much cash in an economy and not expect inflation.
If you think the dollar is worth less then no doubt that's reflected in say gold prices, which were between 1600 and 1900 from July 2011 to April 2013. They are currently 1800. If all that extra money had devalued fiat currencies globally (at roughly the same value), why hasn't gold increased?
Of course, that leads to the question of "what would serve as a good proxy for the actual value of currency", and I don't have a good answer to that. CPI is the traditional answer, but I don't think it's a sufficient one because
1. CPI misses out on some of what people care about (e.g. asset prices are actually important in determining what kind of long-term lifestyle people can afford) 2. We want to disentangle "commodities went up because of supply shocks that will resolve themselves" and "commodities went up because money is permanently worth less", to the extent that it is even meaningful to disentangle these things
So yeah, it is entirely possible that the dollar is worth less [relative to what people care about], and also gold is worth less [relative to what people care about], and it is even possible that that is causally downstream of injecting a bunch of dollars into the economy, but I have no idea how one would robustly demonstrate that that was or was not the case. If you have any ideas on that front I'd love to hear them.
Also if you are aware of any assets that are _strongly and reliably anticorrelated_ with most other assets during recessions, I would be interested for much more personal reasons.
