There is no real definition to “hyperinflation”. Some use it as “out of control inflation”, whereas for others it is an act of rejection of a particular currency. Similarly, deflation is sometimes considered a pricing phenomena, whereas others consider it a reflection of money supply or credit. Personally, I use “hyperinflation” to mean the active rejection of a currency (infinite velocity, plummeting value versus more stable currencies, etc.), and “deflation” to be a measurement of credit. Neither term, as I choose to use it, is a term about prices, but rather underlying conditions — the pricing phenomena is the result of those conditions. By those definitions (rejection of currency, collapse of credit), there is no inherent contradiction. They could both occur simultaneously.
Given that others choose to use the terms to reflect pricing, however, I can see why you would say they are contradictory.
No. No. No.
You have made an assertion without backing it up.
Hyperinflation is the complete loss of confidence in a currency leading to a catastrophic increase in the price of goods and services.. Deflation is the drop in prices attributed to the increase in a currency's purchasing power.
You have not shown a connection between them at all.
