Bitumen Deposits in Nigeria Explained: Reserves, Uses and Value

Nigeria holds some of the world’s largest bitumen (natural asphalt) reserves, concentrated in the southwest — yet it still imports bitumen for road construction. That gap between reserves and use is one of the country’s clearest FX stories, because every imported tonne is paid for in dollars and tracks the exchange rate.

Why bitumen matters

• Roads — bitumen binds the asphalt that paves highways.
• Construction — waterproofing and surfacing.
• Reserves vs imports — large deposits, but limited local production.

The dollar and the roads bill

Because much bitumen is imported, a weaker naira raises the cost of road projects — the same force behind building-material prices and crude oil. Developing local deposits would cut the import bill and save FX, a recurring theme across Nigeria’s solid minerals, from tin to oil.
