What would happen if Iran returned to the global trade order? in World Economy News 27/01/2026 Picture Iran rejoining the global system after decades of sanctions — banks back on SWIFT, oil exports restored, capital returning. Iran is often described as a sleeping economic giant. The country of over 85 million people holds vast oil and gas reserves, as well as occupying a strategic location linking the Middle East, Central Asia, and Europe. Even so, the nation trades far below its potential because of decades of sanctions. The scale and persistence of the recent protest movement has revived hopes of a future inflection point — one that could force a political break and, eventually, a reopening to trade. If that happened, the consequences would extend far beyond Iran’s borders. After decades of isolation, the country could be re-plugged into the global financial system. Banks could reconnect to SWIFT, oil exports could flow without restraint, and foreign direct investment could return at scale. This would not merely be a domestic recovery. It would be a shock powerful enough to reorder trade, energy, and capital flows across the Middle East. A one-year shock In the immediate aftermath of any diplomatic or political breakthrough, the lifting of sanctions would likely trigger a rapid rebound — like a tightly wound coil suddenly being released. Iran’s non-oil trade, long capped at around $100bn (€85bn), could expand sharply. Estimates of latent capacity run as high as $182bn (€155bn) once restrictions are removed, although this figure is exposed to a number of variables. A key early driver would be Iran’s reconnection to the SWIFT global payments system. Under sanctions, transaction costs have been pushed higher through informal and shadow-banking channels. Restoring normal access could cut those costs, unleashing pent-up demand and fuelling an import surge in the first year — particularly for capital goods, industrial machinery, and higher-end consumer products needed to modernise Iran’s ageing infrastructure. Early regional spillovers The regional effects could be swift, and Turkey, as Iran’s main land gateway, would be among the first beneficiaries. Rising demand for Turkish consumer goods and services could notably translate into a tourism boost. Iranians previously constrained by currency controls — and still facing visa hurdles for Europe — would be expected to travel in larger numbers to Istanbul and Antalya. At the same time, European and American cultural tourists could slowly begin returning to Iran. Analysts estimate that within the first year, 5–7% of Turkey’s cultural tourism market could tilt towards destinations such as Isfahan and Shiraz. With a large portion of Iran’s aircraft grounded due to ageing fleets, Turkish airlines would likely step in, adding daily routes. For Iraq and Pakistan, the gains could be more macroeconomic if the Iranian regime fell. Stable, direct energy supplies from Iran would lower production costs and ease inflation. Energy market shock The impact may be felt most sharply in energy. Iran’s return could add up to 1.5 million barrels a day of crude to global supply. Unless OPEC+ moved to offset the increase, analysts warn oil prices could fall by around 10% — a windfall for importers such as Turkey and Pakistan, but a squeeze on the budgets of producers including Saudi Arabia and Kuwait. In gas, too, the balance could shift. Iran’s re-entry would challenge Qatar’s long-standing dominance of the shared
