Tehran’s equity market barrelled to a record high in the week ending 11 June, then extended its rally spectacularly on the first trading day of the new week, as investors bet that Iran and the United States are inching towards a political understanding. The benchmark TEDPIX closed at 4,593,000, a weekly gain of 5.4 per cent, while the equal-weighted index surged 6.3 per cent to 1,235,000 — its strongest showing of the year and a clear sign that buying was cascading beyond the large-cap names into small and mid-cap stocks. On Saturday, 13 June, the momentum intensified: the main index vaulted another 97,464 points, or 2.1 per cent, to breach 4.69 million in a session marked by a rush of buy orders that overwhelmed sellers.

Half a world away, Indonesia’s Jakarta Composite Index (IHSG) recorded an even sharper lift. Over the same trading week the IHSG soared 7.4 per cent to 6,007.656, propelling market capitalisation 7.3 per cent higher to 10,524 trillion rupiah. The exchange reported that average daily transactions climbed 4.1 per cent, as frequency and volumes pointed to broad-based enthusiasm across Southeast Asia’s largest bourse.

Analysts in Tehran caution that the surge is not merely a reflex to diplomatic headlines. Even before the latest signals from the negotiating table, Iranian equities were trading at valuations many considered attractive, while corporate earnings had been quietly recovering. A series of exchange-rate policy adjustments boosted the rial value of export revenues, strengthening balance sheets across the petrochemical and metals sectors. In that view, the fundamental groundwork for a rally was already laid; geopolitical optimism acted as a trigger rather than the sole engine. Market watchers noted that the year-to-date performance gap — the equal-weight index up 30 per cent against 24 per cent for the headline gauge — underscores how deeply the recovery has permeated the exchange.

Whether the rally can be sustained hinges almost entirely on the substance and sequencing of any agreement. A durable de-escalation that lifts sanctions would likely channel both overseas capital and dormant domestic savings into the Tehran market, while any breakdown in talks would reverse the risk-on trade with equal speed. For now, the simultaneous surges in Tehran and Jakarta highlight a moment when emerging-market equities are rediscovering political oxygen and liquidity. The weeks ahead will test whether this is the start of a structural repricing or a tactical burst of exuberance that still awaits concrete policy delivery.
