Primarily Nigeria's inflation started when the government closed its borders for food they can't produce to meet up expectations, then the government borrowing also led to Naira devaluation which all contributed,.

Secondarily marketers indiscriminately add prices to their goods due to non regulations by govt agencies. I went to buy Bluetooth adapter for my car, the shop owner said 3000 I later bit him down to 2500, this was supposed to be 1500. He said he was selling it high because he doesn't know how much he's going to buy another one. Now he sold way above cost price just for the fear of what he's going to buy not that his suppliers actually have increased their price. So with this mentality inflation keep soaring. Funny thing is that this same man will have to also buy things at a costlier amount when he gets to buy things he doesn't sell and the cycle continues
