In late 1981 mortgage interest rates were >18% annually. Inflation rates were well above 10% at several points in the 1970s and early 1980s.
Of course the future can always be worse than the past. But the not so distant US past was already pretty extreme relative to what I've experienced my entire adult life. And basically the same preparations work for inflation, whether we're talking an increase to 10%/year, or 10%/month.
As a child of the seventies, I always expect and plan for inflation. Our weapons: a Defined Benefit Pension that includes COLAs, mortgaged rental properties, and an equity heavy portfolio. And mad mustachian skillz.
In hyperinflation, COLAs likely fall behind rises in living expenses. But an equity heavy portfolio is going to do a much better job of preserve wealth through inflation, or even hyperinflation, than one heavy on bonds/cash. And rental properties mortgaged at long term fixed interest rates will actually produce more net income in real terms if inflation kicks up than if it does not.
Not saying it'd be fun, but Dicey's formula sounds like the best recipe available.
I'm not sure anything can effectively prepare/hedge against Weimar Republic/Venezuela inflation. At that point the negative effects of inflation move from the fiscal to the political. I don't know that there is a way to invest to be protected from wide-scale unrest and lawlessness, the rise of totalitarian regimes, asset confiscation/nationalization, etc.
