TEHRAN — The Tehran Stock Exchange will reopen after an 80-day closure tied to the war with the United States and Israel. Shares, equity funds and equity-linked derivatives will resume trading on Tuesday and Wednesday before the Iranian weekend.

The market had been shut since February 28, when the U.S. and Israel launched missile attacks on Tehran and other parts of Iran. U.S. and Israeli fighter jets extensively bombed Iran's economic infrastructure during the war, including petrochemical companies, steel producers, and mining and transport-linked firms that rank among the top performers in the capital market.

Trading sessions will be extended by one hour to accommodate top firms disclosing information after sustaining war damages and those that held shareholder meetings during the closure. Iranian authorities set a limit where most shares on the Tehran Stock Exchange and the Fara Bourse can rise or fall only three percent from the previous closing price in one trading day.

Securities and Exchange Organization Chairman Hojatollah Seyyedi said companies will be divided into three categories for the reopening. The first comprises companies with direct war damage, including petrochemicals and steel producers. The second covers companies affected through suppliers, customers, or subsidiaries. The third comprises firms affected by the general environment.

SEO deputy Hamid Yari said, "The move was aimed at protecting investors' assets, preventing emotional behaviours, and creating conditions for trade in the market with more accurate and transparent information." According to Donya-e Eqtesad, companies may submit sensitive data, such as maps, production processes and designs considered commercial secrets, to the SEO without full public disclosure online.

Bijan Khajehpour, managing partner at Eurasian Nexus Partners, addressed the risks tied to the resumption of trading. "The reopening of the stock exchange will have to be closely controlled as there are serious concerns that investors will engage in panic selling to generate liquidity," he said.

TEDPIX, the main index of the Tehran Stock Exchange, stood at nearly 3.7 million points at the last pre-closure market snapshot. Expectations of war with the U.S. and Israel had led investors to withdraw funds from the market. In the weeks after the June 2025 ceasefire, the index dropped by over 15 percent, before reaching an all-time high of nearly 4.5 million points at the start of 2026.

The U.S. imposed a naval blockade on Iran's ports on April 13, five days after a ceasefire agreement.
