For several African countries, oil makes up a large part of the entire economy
Oil rents are the value of oil production left after the costs of extracting it, and for some African countries they make up a large share of total economic output. For nations most reliant on oil, this income can dominate government budgets and export earnings. When oil prices rise, revenues surge; when they fall, budgets can collapse quickly. Economists call the problems that often follow the resource curse, though outcomes depend heavily on how governments manage the income.
Oil is valuable but its income depends on world prices, which are volatile. Governments collecting large oil revenues can become less dependent on taxing citizens, which can weaken accountability, and the currency can strengthen so that other exports become harder to sell abroad.
Heavy reliance on one commodity makes economies vulnerable to global price swings and can crowd out farming and manufacturing. It is a central reason why African development strategies focus on diversifying exports.
Norway is often cited as a counterexample: it built a large sovereign wealth fund from oil income and avoided many of the usual problems, showing outcomes depend on policy.
