In my country, what causes economy problems is the rise of petroleum, fuel and other gaseous substance, once the price of these chemicals go up, then the economy is in doom where it's hard to solve the problems, everything rises in price even a product that doesn't use fuel to function.
The amazing part is that, the government officials never care much about this but always come up with fail projects to lift this matter.
I suppose you are referring to Nigeria my country. Our problem has been subsidy and corruption. You see, fuel isn't cheap in all places, even in the countries that are the biggest oil producing countries doesn't but fuel/gasoline very cheap. Here is our problem and things that has been going down:
We soley depend on oil for our revenue, this is the biggest place Nigeria generates its revenue but was subsidizing the one sold to the people in the country, reason is that we are as a country we are don't have much money to feed and cutting down the price will help the average person live a simple life but the subsidies momey wasn't really doing anything, they are been stolen by cabals. Now that the government has decided to remove the subsidy, the average life of a common man isn't longer the same, everything is just hard because everything you can mention now depend on fuel.
The latest problem we have now is the removed subsidy is no where to be found, don't know where this government is going but we will found out if they get out of office.
