Debasing the currency refers to the all too common historical process of lowering a currency’s actual value. In the past, this phrase commonly came to be associated with commodity money made principally from either silver or gold. Should the sum total of silver, gold, nickel, or copper be reduced, then the physical money is called debased. Even venerable institutions like the Roman Empire, with a thousand year history of growth and stability, have stooped to such debasing of the currency.
Reasons that a government chooses to debase the currency in this way center around the financial benefits that the government is able to reap. These are done at the citizenry’s expense though. Governments that lowered the quantity of gold and silver in their coinage found that they could quietly mint more coins from a given fixed quantity of metal on hand.
The downside to this for the general population centers on the inflation that this in turn causes. Such inflation is yet another benefit for the currency debasing government that then finds that it can pay off government debt or repudiate government bonds easier. The populace’s purchasing power is significantly reduced as a result of this, along with their then lowered standard of living.
Debasing a currency lowers the value of the currency in question. Given enough time and abuse by the governing authorities, this debasing can even lead to a collapse in the existing currency that causes a newer currency or coinage to be created and launched for the nation or state.
