Since I first estimated Iran's hyperinflation at 69.6% per month, many people have asked, how long will it last? To answer that question, I have posted my "Hanke Chart of the Day" and will let the data speak for themselves.

On second thought, perhaps I should offer some "tweet-able"  hyperinflation-duration takeaways:

• The average duration of hyperinflation is roughly 12 months.
• The longest duration of hyperinflation is 58 months (4 years and 10 months), which occurred in Nicaragua from June 1986 until March 1991.
• The shortest duration of hyperinflation is one month (see numbers 46-57).

When it comes to Iran and the probable duration of its hyperinflation, the specter of  "a horrible end" or "a horror without end" comes to mind.
