The TUNINDEX closed Thursday's session, March 12, 2026, up 1.51% at 15,499.14 points, displaying remarkable resilience against volatile international oil markets where Brent crude settled at $96.42 per barrel (+4.8% on the day), spiked by Middle East geopolitical tensions. This performance comes as Tunisia, a net energy importer, saw its currency depreciate 0.74% against the dollar to TND 2.9185 per USD, a move that would typically weigh on equity valuations. However, a targeted rally in the banking sector and major corporate activity surrounding SOTUVER reversed traditional macroeconomic logic.
Market Context: Large Caps Lead the Broader Index
The TUNINDEX20, tracking large-capitalization stocks, outperformed with a gain of 1.75% to 6,908.40 points, compared to 1.51% for the broad index, signaling concentrated buying in liquid names. Market breadth showed a mixed profile with 25 stocks advancing, 22 declining, and 28 unchanged out of 75 listed securities, according to Tunis Stock Exchange data. This 1.14 advance/decline ratio reveals marked investor selectivity, favoring sectors exposed to domestic economic cycles over those sensitive to external shocks.
Banking Sector Powers the Rally
The banking sector constituted the primary engine of the session, with BIAT climbing 3.5% to TND 145.99, BNA advancing 3.7% to TND 14.88, and ATB rising 3.9% to TND 3.74. This surge occurs in a context where dinar depreciation against the dollar (+0.74%) could paradoxically benefit institutions holding foreign currency assets and foreign exchange operations. Furthermore, the Financial Market Council (CMF) announced Thursday an extension of the deadline for submitting applications for the position of independent director and risk committee president at BH BANK, demonstrating intensified governance requirements that reassure institutional investors regarding managerial stability in the sector.
The contrast between banking performance and real estate weakness illustrates the structural dichotomy of the Tunisian market, where financial institutions, whether state-owned like BNA or private like BIAT and ATB, capitalize on rising interest rates and foreign exchange activity to offset anemic growth in lending to the economy. ATB's 3.9% advance to TND 3.74 and BNA's 3.7% rise to TND 14.88 suggest investors anticipate resilience in net interest margins despite currency depreciation, as foreign currency claims generate favorable conversion revenues.
