A paper currency system contains the seeds of its own destruction. The temptation for the monopolist money producer to increase the money supply is almost irresistible.
In such a system with a constantly increasing money supply and, as a consequence, constantly increasing prices, it does not make much sense to save in cash to purchase assets later.
A better strategy, given this scenario, is to go into debt to purchase assets and pay back the debts later with a devalued currency. Moreover, it makes sense to purchase assets that can later be pledged as collateral to obtain further bank loans. A paper money system leads to excessive debt.
This is especially true of players that can expect that they will be bailed out with newly produced money such as big businesses, banks, and the government.
We are now in a situation that looks like a dead end for the paper money system. After the last cycle, governments have bailed out malinvestments in the private sector and boosted their public welfare spending. Deficits and debts skyrocketed. Central banks printed money to buy public debts (or accept them as collateral in loans to the banking system) in unprecedented amounts. Interest rates were cut close to zero. Deficits remain large. No substantial real growth is in sight.
At the same time banking systems and other financial players sit on large piles of public debt. A public default would immediately trigger the bankruptcy of the banking sector. Raising interest rates to more realistic levels or selling the assets purchased by the central bank would put into jeopardy the solvency of the banking sector, highly indebted companies, and the government.
It looks like even the slowing down of money printing (now called “QE tapering”) could trigger a bankruptcy spiral. A drastic reduction of government spending and deficits does not seem very likely either, given the incentives for politicians in democracies.
So will money printing be a constant with interest rates close to zero until people lose their confidence in the paper currencies? Can the paper money system be maintained or will we necessarily get a hyperinflation sooner or later?
