As the country suffers, Iran’s parliamentarians and financiers are growing increasingly fed up with Mr Ahmadinejad’s cack-handed management of the economy. In 2008 Tahmasb Mazaheri, his second central-bank governor (the president sacked the first), gave warning that Mr Ahmadinejad’s policy of low interest rates risked sparking hyperinflation. The president insisted that interest rates not only be kept low, but below the inflation rate. The president ignored those warnings and so in desperation the central bank decided to withhold credit.
