CBN Reforms Boost Nigerian Banks' Market Cap to N25.6 Trillion

Nigerian banks have seen a substantial increase in their market capitalization, reaching N25.6 trillion as of July 17, 2026. This surge represents a 58.6% jump, or N9.45 trillion, from N16.12 trillion recorded in December 2025. The growth is largely attributed to reforms initiated by the Central Bank of Nigeria (CBN), which have revitalized investor interest in the banking sector.

These reforms encompass crucial measures such as the sector's recapitalization, ensuring stability in the foreign exchange market, implementing a tighter monetary policy, and strengthening corporate governance. These initiatives have collectively fostered a more attractive investment climate for banking stocks on the Nigerian Exchange Limited (NGX).

Guaranty Trust Holding Company (GTCO) and Zenith Bank Plc emerged as top performers. GTCO's market capitalization climbed to N4.72 trillion from N3.3 trillion in 2025, while Zenith Bank's rose to N4.68 trillion from N2.54 trillion. Both banks have demonstrated sustained impressive corporate earnings, which have positively impacted their stock prices. GTCO's stock appreciated by 42.45% year-to-date, closing at N129.20 per share, and Zenith Bank's stock gained 84.47% year-to-date.

Other major banks also experienced significant market capitalization growth. First Holdco Plc saw its market cap more than double to N4.36 trillion. Stanbic IBTC Holdings and United Bank for Africa (UBA) also crossed the N2 trillion mark. Banks like Access Holdings, Ecobank Transnational Incorporated (ETI), Fidelity Bank Plc, and Wema Bank Plc entered the N1 trillion market capitalization club, with ETI and Fidelity Bank notably surpassing this threshold during the period.
