There Is No Disinflation

A new record: the monetary inflation starting in the US as far back as 2009/10 is still under way more than 15 years later. There has been no episode of serious monetary disinflation such as would create a meaningful intermission before the next monetary inflation. Under the fiat or hybrid fiat money regimes since 1914 the previous joint record for longest monetary inflation without break was 10/11 years, as in 1938–48, 1962–73 and 1995–2006. Typically, unbroken spells of monetary inflation have been shorter—including 1921–8, 1933–6, 1950–56, 1976–80, 1985–9, 1991–4.
