Paris Stock Exchange Fluctuates Amidst Middle East Tensions and Energy Price Volatility
The Paris Stock Exchange experienced a volatile trading day on March 21, 2026, initially showing gains before reversing course due to fluctuating energy prices and escalating tensions in the Middle East. The CAC 40 index oscillated around equilibrium, reflecting investor uncertainty.
Energy Price Swings Drive Market Uncertainty
The primary driver of market fluctuations was the erratic behavior of energy prices. TTF gas, the European benchmark, fell to 60 euros per megawatt hour on March 19, 2026, after a previous surge to 74 euros (+35%). However, the price of Brent crude oil climbed back above the $110 per barrel mark, providing some support to energy companies like TotalEnergies, which saw a modest recovery from its intraday lows (-0.6%).
According to Euronext Paris data updated on March 17, 2026, the CAC 40 was down -1.82% at 7,665.62, while the CAC ALL SHARES index fell -1.77% to 8,760.51.
Geopolitical Risks Escalate
Initial optimism stemming from signs of de-escalation was dampened by reports of attacks on 16 Iranian ships in a Gulf port. Iran responded with further attacks against neighboring countries, despite assurances from Israel that it would not target Iranian energy infrastructure. Israel has confirmed carrying out strikes on targets within Iran, including in the capital, prompting retaliatory missile strikes from Iran.
Investor sentiment has shifted towards a more pessimistic outlook, as noted by David Kruk, head of trading operations at La Financière de l’Echiquier in Paris, who stated, “The market was wrong at the start of the conflict, thinking it would end quickly.”
US Policy and Potential Sanctions Relief
The United States has urged Israel to refrain from striking the Iranian South Pars gas field, a request which Prime Minister Benjamin Netanyahu reportedly accepted. US Treasury Secretary Scott Bessent indicated on Fox News that the Trump administration is considering easing sanctions on Iranian oil, following a temporary lifting of sanctions on Russian oil. Crude prices currently stand at $107.5 per barrel for Brent, despite ongoing Iranian strikes against Bahrain, Kuwait, and the United Arab Emirates.
Strait of Hormuz Concerns
Concerns regarding the security of the Strait of Hormuz, a critical waterway for global oil and LNG transport, have resurfaced. France, Germany, Italy, the United Kingdom, the Netherlands, and Japan jointly issued a statement supporting efforts to “guarantee the safety of navigation in the strait,” emphasizing the fundamental principle of freedom of navigation under international law. Approximately 25% of seaborne oil and nearly 20% of global LNG pass through the Strait of Hormuz annually.
