It's higher than that, because the CPI does a lot of adjustments to the offical figure. Moreover, your years are cherry-picked; there was a wave of deflation (that occurred in 2008-2009) as loans went though a cycle of defaults to clear out bad debt. Finally, the effects of top-down stimulus take a long time to propagate, especially since the current money multiplier for dollars is still quite low, and bank's lending activities have been relatively stagnant (roughly speaking, base currency went up, but debt expansion, which is what really counts, has not caught up yet because people are reluctant to go into debt - hence the popularity of debit cards vs. credit cards). Eventually as people start using debt to paper of catastrophes and emergencies, the overall indebtedness will increase, and the inflationary increase in the base currency will propagate into the debt burden, and we will have a sudden increase in inflation.
I personally think it's unlikely to be hyperinflationary, but it will be very uncomfortable, especially for poor and middle class.
But, perhaps i should not have used the past tense.
Inflation actually tends to benefit the poor in the long run, as it devalues debt. (By definition, the poor don't have a lot of savings and tend to be in debt). Hyperinflation of course causes problems for everyone, but that's not going to happen. That said, there's little reason to worry about out of control inflation for several years to come: these economies still have enormous under-utilized resources.
No. The poor are typically in debt on short-term scales (days, weeks) which does not benefit from inflation, and at rates (often double digits) which inflation does not mitigate.
The rich are typically in debt a lot, via leveraged investment ('trading on margin'), or, indirectly by things like leveraged ETFs, leveraged currency FX trading, etc, which enjoy very low, bank-level interest rates because it's done in bulk. Not to mention banks with direct access to low-interest loans, (as in bank corporations) which are not begging in the streets for alms (they get bailouts). These debts that the rich enjoy benefit greatly from inflationary devaluation of nominal prices.
Moreover, the investment activity of the rich tends to benefit from inflation.
While I'm sure there are some rich that are heavily leveraged, the majority are not leveraged that highly relative to their asset base. This has been shown in most available statistics on household wealth. For example:
In particular the debt-equity ratio of the top 1% (>$8.2m net worth) is 2.8% ; the next 19% (> $473k < $8.2m) is 12.1%, and the middle three quintiles ($200 dollars-$480k) is is 61.1%.
Moreover, the rich representatives in press & politics (WSJ editorial page, Forbes, the GOP, etc.) have been clamouring to raise interest rates for the past 5 years out of inflation fears... for what reason? To benefit the poor?
I personally think it's unlikely to be hyperinflationary, but it will be very uncomfortable, especially for poor and middle class.
