Should central banks succeed in jacking up inflation, devaluing the purchasing power of fiat currencies and pushing stocks to the moon, they will have failed their citizenry. Should they succeed in reaching their goals, they will trigger catastrophic instability.
Central banks around the world share a few simple goals:
1. Defeat deflation by sparking inflation--in the cost of goods and services, not wages.
2. Weaken the currency to boost exports and counter beggar thy neighbor devaluations by other exporting nations and trading blocs.
3. Boost the value of stocks to keep pension plans afloat and project a politically powerful message of "growth" and "prosperity."
What no central bank dares say is what happens should they manage to boost inflation, devalue their currency and continue pushing assets higher: when we succeed, we fail.
Consider the consequences of juicing inflation: every click up in inflation further reduces the purchasing power of wages, which do not keep up with inflation in a world of labor surplus.
