CBN Spends $1.4bn on FX Defence in July, Yet Naira’s Stability Masks Strong Demand

The Central Bank of Nigeria sold roughly $1.4 billion in foreign exchange during July, its highest monthly intervention since April 2025, according to FMDQ data. The naira still closed July at N1,368/$, stronger than June’s N1,376/$, but average rates and pressure in the parallel market show a currency under persistent demand.

On the surface, the N8 month-end appreciation supports the story of a calmer FX market. But the numbers tell a more nuanced story. The naira’s average exchange rate weakened by 0.4 percent month-on-month to N1,373.43/$ in July, from N1,368.14/$ in June. That means month-end strength did not reflect the underlying market reality, where demand for dollars kept pushing against the currency.

Why the CBN Had to Step In

The scale of intervention is the clearest sign of pressure. The $1.4 billion sold in July is the highest since April 2025, when sales were also about $1.4 billion. It shows the CBN’s determination to keep liquidity in the official market and avoid excessive volatility.

Offshore inflows remain subdued. Foreign portfolio investors and international participants are cautious, citing global uncertainty, tighter risk management, and increased risk aversion. With weaker offshore participation, domestic FX demand is competing for a smaller pool of foreign exchange, so the CBN is acting as a bridge between supply and demand.

The big question for investors is sustainability. If official intervention has to stay this large, how durable is the current stability?

Parallel Market Sends Warning Signal

The parallel market also shows demand pressures are elevated. The naira weakened to N1,415/$ at the end of July, from N1,405/$ in June. That N10 depreciation contrasts with the N8 appreciation recorded in the official market over the same period.

While the parallel market does not set the official exchange rate, it is an important sentiment indicator. It reflects participants who cannot or will not access FX through formal channels. A sustained gap between official and parallel rates could hurt confidence, especially if businesses start pricing FX costs at the parallel rate. For investors, the spread influences expectations about future exchange-rate moves, affecting capital allocation, repatriation, and hedging decisions.

Seasonal Demand and What It Means for the Naira

Seasonal demand is expected to add more pressure in the near term. Analysts expect elevated demand as businesses and market participants increase foreign exchange requirements in the months ahead.

Nigeria’s external position offers some support. Robust external reserves give the CBN room to intervene when pressure builds, and stronger export proceeds should improve underlying FX supply. This is a big improvement from the days of severe dollar shortages, sharp exchange-rate swings, and a large official-parallel gap. The market is more orderly now.

But July shows the underlying demand imbalance has not gone away. With $1.4 billion in intervention during a single month, the naira’s stability still leans heavily on official action. For businesses and consumers, that means exchange-rate calm can quickly turn fragile if the CBN’s capacity or willingness to spend at this pace changes.
