There are many, many versions of the hyper inflationary episode that occurred in 1920’s Germany but the following by Art Cashin writing at ZeroHedge is one of the most concise and readable that I have come across (emphasis mine, more after the excerpt) :

Originally, on this day (-2) in 1922, the German Central Bank and the German Treasury took an inevitable step in a process which had begun with their previous effort to “jump start” a stagnant economy. Many months earlier they had decided that what was needed was easier money. Their initial efforts brought little response. So, using the governmental “more is better” theory they simply created more and more money.

But economic stagnation continued and so did the money growth. They kept making money more available. No reaction. Then, suddenly prices began to explode unbelievably (but, perversely, not business activity).

So, on this day government officials decided to bring figures in line with market realities. They devalued the mark. The new value would be 2 billion marks to a dollar. At the start of World War I the exchange rate had been a mere 4.2 marks to the dollar. In simple terms you needed 4.2 marks in order to get one dollar. Now it was 2 billion marks to get one dollar. And thirteen months from this date (late November 1923) you would need 4.2 trillion marks to get one dollar. In ten years the amount of money had increased a trillion fold.

Numbers like billions and trillions tend to numb the mind. They are too large to grasp in any “real” sense. Thirty years ago an older member of the NYSE (there were some then) gave me a graphic and memorable (at least for me) example. “Young man,” he said, “would you like a million dollars?” “I sure would, sir!”, I replied anxiously. “Then just put aside $500 every week for the next 40 years.” I have never forgotten that a million dollars is enough to pay you $500 per week for 40 years (and that’s without benefit of interest). To get a billion dollars you would have to set aside $500,000 dollars per week for 40 years. And a…..trillion that would require $500 million every week for 40 years. Even with these examples, the enormity is difficult to grasp.

Let’s take a different tack. To understand the incomprehensible scope of the German inflation maybe it’s best to start with something basic….like a loaf of bread. (To keep things simple we’ll substitute dollars and cents in place of marks and pfennigs. You’ll get the picture.) In the middle of 1914, just before the war, a one pound loaf of bread cost 13 cents. Two years later it was 19 cents. Two years more and it sold for 22 cents. By 1919 it was 26 cents. Now the fun begins.

In 1920, a loaf of bread soared to $1.20, and then in 1921 it hit $1.35. By the middle of 1922 it was $3.50. At the start of 1923 it rocketed to $700 a loaf. Five months later a loaf went for $1200. By September it was $2 million. A month later it was $670 million (wide spread rioting broke out). The next month it hit $3 billion. By mid month it was $100 billion. Then it all collapsed.

Let’s go back to “marks”. In 1913, the total currency of Germany was a grand total of 6 billion marks. In November of 1923 that loaf of bread we just talked about cost 428 billion marks. A kilo of fresh butter cost 6000 billion marks (as you will note that kilo of butter cost 1000 times more than the entire money supply of the nations just 10 years earlier).

It is striking to me (emphasis in the excerpt) how alike 1920’s Germany and 2010 USA are (and to some extent the UK as well). Stagnant economies, lack of jobs growth, easing of monetary policy and talk, in the US at least, of more of the same.

Whether the outcome will be the same is the subject of much (heated) discussion by camps on both sides of the inflation divide but if it does it certainly gets ugly pretty damned quickly.

To end, what better than to quote Keynes :

Lenin was certainly right. There is no subtler, no surer means of over-turning the existing basis of society than to debauch the currency.
