Zimbabwe Inflation: The End of the Story

As we went to press with Modern Principles: Macro we kept having to add zeroes to Zimbabwe's peak hyperinflation rate and move it up the table of world leaders.  In our final revision, Zimbabwe's inflation rate had hit 79,600,000,000% per month putting Zimbabwe in second place.  We wondered whether in our  second edition Zimbabwe would overtake the all time hyperinflater, Hungary (1945-1946) at 41,900,000,000,000,000% per month, but it was not to be.  As it turned out, we went to press just as the hyperinflation peaked and Zimbabwe's currency ceased to exist as a medium of exchange.  Steve Hanke at Cato has the end of the story

Ashes are all that is left of the Zimbabwe dollar — a remnant of paper money. During Zimbabwe’s hyperinflation, foreign currencies replaced the Zimbabwe dollar in a rapid and spontaneous manner. This “dollarization” process was legalized in late January 2009. Even though the Zimbabwe paper money remnant circulates alongside foreign currencies, its real value is tiny, its use is limited, and its value against the U.S. dollar is cut in half every two days.

Zimbabwe failed to break Hungary’s 1946 world record for hyperinflation. That said, Zimbabwe did race past Yugoslavia in October 2008. In consequence, Zimbabwe can now lay claim to second place in the world hyperinflation record books.

Final Postscript: In 2009, Zimbabwe's central banker, Gideon Gono, was awarded the Ig Nobel prize, not, as expected, in economics but in mathematics for, in the prize committee's words, "giving people a simple, everyday way to cope with a wide range of numbers — from very small to very big — by having his bank print bank notes with denominations ranging from one cent ($.01) to one hundred trillion dollars ($100,000,000,000,000)."

I understand the allure of huge annual inflation percentages-- they're comic and dreadful at the same time. However, in real life, what one actually needs to know is the half-life. The half-life cited above of two days is pretty impressive, since it corresponds to an annual factor of... 2-to-the-minus-(365/2)-th power.

So Zimbabwe had 0% unemployment that whole time, right? Because everyone keeps saying inflation is impossible here what with all the excess capacity.

we ended up having to increase some database field sizes because of the ZWD/USD exchange rate at one point. it's possible that this sort of thing increased GDP in the rest of the world.

In terms of a currency, the highest denomination of a currency ever
apparently still remains the Hungarian one at the peak, 5 quintillion
pengos. That was achieved by taking old banknotes and putting exponents
on the numbers and then taking them back in again and putting exponents
on the exponents. Hot stuff.

As far as the motivations of Gideon Gono, I'll speculate that he had direct financial connections to the printer of the currency. So while the need to span 17 orders of magnitude in currency is questionable (to say the least) the motivations are (possibly) more understandable.

Three significant figures!?

It's not just measurement error, but under hyperinflation, money probably doesn't have a sufficiently meaningful value that there is such a precise right answer.

Maybe you can say that the (geometric) average over the month really is 195% per day (cf MattF endorsing the half-life), but compounded over a month, that's not even 2 full sig figs.

But are there more Zimbabwe dollars in circulation than there are particles in the known universe? Supposedly this was true of the pengo. In college the estimate for particles was 10^80, but a short web search shows people now claiming between 10^72 and 10^87.

And no one got to jail. A robber would be jailed over depriving an owner of $100, but here the government deprived its subjects of billions.

Babar - would you like us to break some windows while we're at it? :)
