CBN Liquidity Mop-Up Bolsters Naira Amid Shrinking Reserves

The Central Bank of Nigeria (CBN) has successfully propped up the naira through aggressive Open Market Operations (OMO), despite a worrying $1.14 billion slide in external reserves. Over a four-day trading week, the local currency gained 1.76 per cent to close at N1,356.89 per dollar at the official window. This recovery suggests that the central bank’s strategy of tightening liquidity is effectively drawing in foreign portfolio investors. By mopping up excess cash, the regulator makes the naira scarcer and more attractive to those seeking high-yield government paper. However, the cost of this stability is becoming visible in the national coffers.

Market data reveals that the naira firmed by N29.77 across four sessions, starting the week at N1,386.66. The parallel market followed a similar trajectory, with the currency gaining N10 to close at N1,400. Curiously, the gap between the official and black-market rates widened to N44, up from N30 the previous week. This divergence often indicates that while official interventions work, retail demand for dollars remains unsated. The central bank mopped up a total of N2.31 trillion during the week to maintain this delicate balance.

Foreign investors are the primary drivers of this appreciation, as they bring in dollars to participate in lucrative OMO auctions. Whenever the central bank drains liquidity, the naira tends to appreciate as these inflows hit the market. This mechanism provides a temporary shield against the structural weaknesses of the Nigerian economy. It is a classic move to incentivise capital entry while the country struggles with lower oil output. For now, the strategy appears to be working, providing a reprieve from the volatility seen earlier in the year.

The backdrop to this currency gain is a significant drain on the nation’s buffers. External reserves fell to $48.88 billion as of April 8, 2026, a 2.28 per cent drop in less than a month. Analysts point to heavy debt service obligations and sustained market interventions as the primary culprits for this depletion. Maintaining the naira’s value requires a constant supply of dollars, which the central bank must provide when private supply falters. A shrinking reserve limits the bank’s ability to defend the currency in the long term.

Global factors and internal policy shifts are adding to the pressure. Recent rules allowing international oil companies to fully repatriate their export proceeds have triggered short-term outflows. While intended to foster transparency and attract future investment, the immediate effect is a strain on available foreign exchange. Oil price fluctuations and high demand for imports also continue to test the central bank’s resolve. Nigeria remains trapped in a cycle where it must spend its reserves to maintain a semblance of exchange rate order.

Looking ahead, analysts expect the naira to enter a period of consolidation with mild depreciation risks. The “willing-buyer, willing-seller” framework provides a market-driven price, but it remains sensitive to supply shocks. High crude prices offer some hope for reserve recovery, yet Nigeria’s inability to meet its production quotas limits the potential windfall. The central bank must decide how much more of the national rainy-day fund it is willing to spend to keep the naira afloat.
