The economic fallout from Iran's 39-day war and ongoing tensions is becoming starkly visible in fiscal and trade data, even as intermediaries manoeuvre to revive lucrative transit routes through the United Arab Emirates. Tax revenues in the first two months of the Iranian calendar year plunged 60% in real terms compared with the same period last year, reaching only 152 trillion rials — a collapse that underscores the war's devastating impact on the domestic economy. The government had budgeted for a 42% nominal increase in tax income, which was meant to cover nearly half of public spending. Instead, revenues from corporate tax, value-added tax, income tax and wealth tax all fell sharply, reflecting widespread disruption to business activity and employment.

Iran's external trade has suffered equally severe blows. Exports to India, a major buyer of Iranian petrochemicals, metals and fruit, dropped 38% in March to just $43 million, while imports from India — a key supplier of agricultural goods, pharmaceuticals and industrial inputs — crashed 72% to below $130 million. Trade with China, Iran's largest non-oil partner, has also shrunk dramatically: non-oil bilateral trade in March and April fell to one-fifth of the level seen a year earlier, averaging only $200 million per month. The disruption has already caused shortages of medicines and vaccines, with Iranian officials reporting import difficulties from India, Pakistan and the UAE.

Against this backdrop, reports from Tehran indicate that certain intermediaries are actively working to restore the pre-war trade relationship with the UAE, which had been a vital hub for indirect commerce. Before the conflict, Iran-UAE trade stood at roughly $25 billion annually, but only 10% of that represented direct bilateral exchange; the rest consisted of goods transiting through Emirati ports. Even a modest 2% fee on such transactions would yield intermediaries $450 million per year — some 80 trillion rials — not counting profits from currency arbitrage and delayed settlements. These efforts come as Iran explores alternative routes, including northern corridors and direct deals with Russia and China, but the entrenched role of UAE-based middlemen remains a powerful counterforce.

Meanwhile, far from the Middle East, China is rapidly expanding its commercial footprint in Latin America. Argentine exports to China surged nearly 80% in the first four months of 2026, while imports from China fell 7%, according to the Argentine-Chinese Chamber of Commerce. The shift has propelled China past Brazil as Argentina's top trading partner in some months of 2025, a development that analysts in Buenos Aires describe as a structural realignment. The trend reflects China's aggressive pursuit of agricultural commodities and energy resources, even as global trade patterns are reshaped by geopolitical tensions.

Looking ahead, the divergence between Iran's isolation and China's global outreach highlights the uneven impact of the current geopolitical climate. For Tehran, the collapse in tax and trade revenues raises urgent questions about fiscal sustainability and the viability of its wartime economic strategy. The push to revive UAE-mediated trade suggests that, despite official rhetoric about self-reliance, the Iranian economy remains deeply dependent on opaque intermediary networks. For Beijing, the gains in Argentina demonstrate a capacity to exploit openings left by traditional powers, though the sustainability of such growth will depend on navigating volatile commodity markets and diplomatic pressures. The coming months will test whether Iran can stabilise its finances without a ceasefire, and whether China can maintain its momentum without provoking a backlash in Washington or Brasília.
