The average cost of making a pot of jollof rice in Nigeria rose by 7.8% between March 2020 and March 2021. This is contained in the SBM Jollof index report for Q1 2021, published by SB Morgen.
According to the report, the increase was caused by the prolonged border closure, increased energy tariffs, exchange rate volatility, coronavirus pandemic, and the restrictions of forex for the importation of items, largely due to falling oil prices.
It also identified the effect of the #EndSARS protest against brutality and the response of the government, which brought the main economic states in Nigeria (Lagos and Abuja) to a standstill for major parts of the month of October 2020.

This is actually funny what do we call this analysis Jollof rice metrics or Jollof rice-nomics.
