In early 1980 there was a 14.5% yearly change in the Consumer Price Index (CPI). The out-of-control effects on the economy required the Fed to slam on the brakes so hard that a long-term recession ensued.
This episode followed an M2 yearly growth rate in the mid-13% area in early 1976
How high has the M2 yearly growth rate been in the past? It peaked at 17.79% in 1943 (WWII).
What is the recent M2 yearly growth rate? In late 2020 it was 25%.
From Blabbermouth's OWN go-to source for a definition of hyperinflation (which ignores the much longer established standard English language*):
'..if the increase in money supply is not supported by economic growth as measured by gross domestic product (GDP), the result can lead to hyperinflation. If GDP, which is a measure of the production of goods and services in an economy, isn't growing, businesses raise prices to boost profits and stay afloat. Since consumers have more money, they pay the higher prices, which leads to inflation. As the economy deteriorates further, companies charge more, consumers pay more, and the central bank prints more money—leading to a vicious cycle of hyperinflation.'

Has GDP kept pace with the growth rate of the money supply? NO, IT HAS NOT. IT HAS LAGGED FAR BEHIND SINCE THE LAST PART 0F 2019.
* A more proper and sensible terminology for a monthly inflation rate exceeding 50% is 'ultrahyperinflation'.
Is inflation currently 'above normal'? Yes, it is.
