1. Egypt's tourism sector got hammered after the revolution, especially in the "Ancient Egypt" route. The beach based tourism remain high.
2. Head of local governments keep changing every 6 months or so. The same thing applies for Cabinet Ministers.
3. Egyptian 25 Jan revolution lasted in full 18 days. It's quite short for a revolution although the repercussion ripples.
4. Basic infrastructure such as electricity and gasoline distribution got affected which adds cost and uncertainty into manufacturing.
5. There are tons of political motivated persecution such as the NGO trials which really scared off Western investors.
6. American Chamber of Commerce invited a hundred US businessmen for investment and arranged them to meet President Morsi only to be evacuated the next day after the Anti-Islam YouTube video.
7. The whole MENA region got engulfed in revolution which really affects the movement of goods and people.
8. Investors from the Gulf really eyed the MB with suspicions. UAE officials routinely publicize sharp comments against the MB.
Anyway, I expect the economy to bounce back strongly in the near future. I am not Egyptian myself although I've lived here for many years. My country Indonesia went through similar revolution 14 years ago and now we are a trillion dollars economy.
