It's funny how people will always overlook the obvious. If you want to hedge against currency dilution then the easy and most obvious play that has always worked in the past and appears to be working again a treat right now is is to store your wealth in things that cannot easily be diluted - hard assets.
Just like the USD-to-Swiss Franc trade is an exchange of US inflation risk for forex risk, going from USD to "hard assets" is a tradeoff of US inflation risk to market risk in real estate, precious metals, or commodities.
"Hard assets" might shield a person from inflation, but they can also suddenly drop 30-40%. So someone who trades all their idle cash for hard assets is not avoiding risk on net, they are trading one type of risk for another. In a sense, any investment decision is a choice about which risks to be exposed to. The herd of investors getting cues from the financial media or their own narrative stories can sometimes swing their risk exposure far in one direction or another. Boom and bust then occurs on both the individual and market-wide levels as large numbers of people decide together that there is
no risk whatsoever in a particular bet.
I can imagine such cycles because I've seen them. E.g. Inflation starts rising. Investors flock to "hard assets". The Fed raises rates. Hard assets rise as recession sets in, and people start making them a permanent majority of portfolios. Then suddenly the hard assets suck compared to stock returns again. The internet was FULL of oil enthusiasts in 2007, real estate geniuses in 2005-2008, goldbugs in 2013, etc. Many of them looked at their past performances and decided they had found The Way to reduce portfolio risk. Then the bottom fell out and the whole herd was panic selling. Late arrivals were especially likely to have bought high and sold low.
The re-balancers did OK, but the people running away from one particular risk after another got slaughtered like a teenager running through the woods in a horror movie.
