It is normal that currency debasement and inflation are not the same thing. Currency debasement is a monetary policy by the central bank to intentionally devalue the currency for many reasons, that can include to reduce the effect of money printing and to improve trade balance among many other reasons. But inflation is a disaster that are not intended for, poor economic handling mostly cause it.

In simplicity, currency debasement affects the currency directly, but inflation affects the goods and services to weaken the purchasing power of the currency.
