Due to this fact, Things are expensive because NIGERIA depends on crude oil through international trade

In what way do you mean that? Nigeria has plenty of oil and the price is stable. At least on this end, Nigeria should be ok, isn't it??!

With a lot of increase in prices, people struggle to feed

It's always worrying when people suddenly have to pay twice or three times to cover their daily needs. The rule is that as soon as food expenses make up 2/3 of people's income, then revolution ensues. I hope you're not affected too much and that Nigeria/Africa can cope and get out of this mess.

PS: Nigeria's population is growing way too fast. You guys have to fix this. With 13.8% less mouths to feed, inflation may be not 18% but only 5% right now.
