The BBC are reporting it so.
I've kept tabs on Zimbabwe for years, especially after meeting some kids in a classroom whose parents were white farmers who emigrated to Australia after their farm was confiscated by Mugabe's cronies.
I don't think Zimbabwe is about to collapse. I believe it has collapsed. I think it has been collapsing ever since Mugabe became president in the early 1980s. In a previous posting, I showed that the HDI index of Zimbabwe has been declining for nearly 20 years. I don't think Zimbabwe is going to suddely "crash". It'll just get worse and worse and worse.
