Introduction: Why Oil Still Matters in Currency Markets

Oil is not just fuel; it’s a market mover.

For many oil-exporting nations, such as Nigeria, oil prices not only affect government revenues but also impact the overall health of the economy, the stability of exchange rates, and investor confidence. Currency values tend to rise when oil prices are high, and fall when oil prices crash, a correlation that has shaped decades of policy, politics, and profit.

Many currency traders even use this price correlation as a direct indicator for when to buy, sell, or hold.

Why Do Oil and Currency Move Together?

For oil-exporting countries, oil sales are a major source of foreign currency inflow. When oil prices rise:

• Export earnings increase
• Foreign reserves are bolstered
• The local currency appreciates due to increased demand and confidence

Conversely, when oil prices fall, foreign exchange inflows drop, weakening the local currency.

This is particularly true for what is called “petrocurrencies”, currencies of countries whose economies are heavily dependent on oil exports. Examples include the Nigerian Naira, Russian Ruble, and Canadian Dollar.

An increase in the price of oil tends to benefit the currencies of oil exporters while hurting those of importers.

When Correlation Becomes a Curse

Overreliance on oil makes economies and their currencies vulnerable to global shocks. In Nigeria, when oil prices dropped in 2015 and again in 2020, the naira came under severe pressure, triggering multiple devaluations and foreign exchange scarcity.

This “oil trap” means:

• Budgets collapse when prices fall
• FX becomes inaccessible
• Businesses struggle with volatility and unpredictability

The Nigerian Context: Is the Naira Decoupling from Oil?

According to a recent Bloomberg report, the Naira is showing signs of decoupling from oil prices. In the past, a surge in crude would lift Nigeria’s FX reserves and strengthen the naira. But today, the cleared FX backlogs, remittance surge, and CBN interventions distort this once-clear relationship.

Still, oil remains deeply embedded in Nigeria’s economic DNA. Roughly 80% of Nigeria’s FX revenue comes from oil. Even if the statistical correlation appears to be weakening, the psychological and economic impact of oil prices on the currency remains high.

What This Means for Businesses and Treasury Teams

Whether the correlation is tightening or loosening, businesses need to stay informed.

Here’s what you should track:

• Oil futures and Brent crude benchmarks are the  leading indicators of FX pressures
• Nigeria’s external reserves are also a strong link to the CBN’s ability to defend the naira
• Official vs parallel market spreads disparities to anticipate policy shifts
• CBN interventions and monetary policy updates
• Geopolitical events that affect the global oil supply

By building this into your treasury strategy, your business can hedge risks, time FX purchases better, and build buffers before macro shocks hit.
