Nigerian Exchange — NGX ASI Crashes 2.36% to 1483 Points as Energy Stocks Plunge Despite Brent Oil Surge

The NGX ASI plummeted 2.36% to close at 1483.13 on Thursday, March 12, 2026, wiping out recent gains even as Middle East tensions sent Brent crude soaring 5.3% to $96.86 per barrel. Defying conventional correlation, the naira strengthened 0.53% to ₦1389.15 per dollar, creating a rare divergence where the local currency appreciates while risk assets tumble, reports Financial Afrik. This sharp decline comes despite MTN Nigeria posting record annual profits exceeding one trillion naira, highlighting the complex sector-specific factors driving market sentiment. Market breadth data reveals deep sectoral paralysis: out of 148 listed stocks, only 30 advanced against 30 decliners and 88 unchanged, according to official Nigerian Exchange data. This 59.5% stagnation rate reflects collective investor hesitation amid oil market turbulence and regulatory uncertainties. Overall trading volumes indicate broad-based profit-taking following weeks of volatility tied to the Central Bank of Nigeria's (CBN) restrictive monetary policy, which maintains benchmark interest rates at historically elevated levels to combat persistent inflation. Nigeria's energy sector particularly disappointed despite the crude oil surge, creating a striking paradox for analysts. Eterna Plc, a petroleum products marketing and lubricants company, crashed 10% to ₦42.30, while SCOA Nigeria, exposed to automotive and petroleum industrial equipment, plunged 9.9% to ₦22.65. This unexpected discount comes as oil prices hit crisis levels of $96.86 per barrel, responding to Iranian tensions disrupting global supply chains. The explanation lies in recent announcements that Dangote Refinery is preparing its IPO on the NGX, potentially upending Nigeria's downstream value chain and eroding margins for existing fuel importers, according to African Markets. Simultaneously, announced an aggressive drilling program of targeting , intensifying upstream competition and pressuring traditional distributors' valuations. The insurance sector suffered unprecedented carnage on Thursday, amplifying the index's downward trajectory. These declines followed the NGX's activation of rights issue on March 11, 2026, per official market bulletins. This capital raising operation forces existing shareholders to subscribe to new shares, creating dilution fears that spread across the entire insurance sector. The National Insurance Commission (NAICOM) is currently imposing drastic recapitalization requirements similar to the banking sector, forcing insurers to raise funds just as market liquidity tightens. Conversely, healthcare and agro-allied stocks served as defensive havens for portfolio managers. , a pharmaceutical leader, hit its daily upward limit of (), while advanced to and gained to . This rotation toward defensive consumer plays illustrates institutional investors' strategies to shield portfolios from oil volatility and regulatory risks weighing on insurers. , providing helicopter services to the petroleum industry, nevertheless gained to , likely on speculation of emergency contracts with oil majors accelerating production amid Iranian tensions and supply disruptions. The foreign exchange context offers an additional paradox partially explaining index weakness. While the naira strengthened to against the dollar (against a structural depreciation trend since the 2023 FX window unification), foreign investors may be taking profits in anticipation of excessive local currency appreciation reducing their dollar-denominated portfolio values. This naira stability contrasts sharply with the South African rand's plunge ( for USD/ZAR at ) and the Egyptian pound ( for USD/EGP at ), positioning Nigeria as a relative island of monetary stability in Africa on Thursday, though without supporting equity prices. In telecommunications, (MTNN) dominated headlines with record annual profits exceeding (over ₦1,000 billion), according to THISDAYLIVE, though the stock did not feature among the session's top movers. This financial performance underscores the telecom sector's resilience against runaway inflation, while traditional sectors like energy and insurance suffer structural transitions. also benefited from the session, rising to , reflecting interest in alternative financial services. Watch for: Final approval of Dangote Refinery's prospectus, which could drain liquidity toward this mega-IPO at the expense of existing petroleum distributors like Eterna and SCOA. Investors will also monitor the CBN's reaction to naira strength, as benchmark rates remain constraining. Brent volatility around amid Iranian tensions will continue dictating Nigerian energy sector movements, while annual results from banks (Zenith, Access, GTCO, UBA) under new recapitalization thresholds promise to be decisive for market direction.
