A series of conflating and unfortunate factors are why the Central African Republic has the most expensive gas in the world.
The first of these factors is geography. As a landlocked country, the CAR does not have easy trade routes. Fuel has to be transported either through the Oubangui River or overland, which makes it costly.
Then you have the issue of political instability, not just in the CAR but in its neighboring countries. Conflict in the Democratic Republic of Congo and Cameroon sometimes interferes with the routes through which fuel is transported, leading to fuel shortages and higher prices.
The country also has infrastructure issues, with less than 300 miles of paved roads. Corruption and government mismanagement are the cherry on top of this toxic cocktail, and the most impacted are the residents of the CAR.
What’s worse, the market affordability for fuel is 446.3 percent, the second-lowest in the entire world after Burundi.
