in case you don't know what this means; the usd inflation is (quite obviously) much much much much much higher. but being hidden in official modified stats of many currencies.
the idea is that while the economy starts moving again the "money velocity" (ie the country's GDP) will increase and release the energy of all that cash they printed.
it happens via stimmy checks and cheap loans, as this is how money is created in to the "real" economy (not the financial economy).
When things get bad more loans will come from the govt. which basically has merged with the central bank at this point. and will be bypassing the "normal" retail banks. And ofc this eventually leads to "convenience" via central bank digital currencies.
