Iran Through Economic
Power Vacuum in Tehran Sends Shockwaves Through Global Markets and Shipping Lanes
Iran's Supreme Leader Khamenei — who held the role for more than three decades and ran every major Iranian state institution through his office — is dead, his funeral procession moving through a Tehran lined with millions of mourners as the country's airspace remains shut down. Military commanders have made loud, public promises of revenge, but analysts note that Iranian hardliners have issued similar demands before, most notably after the killing of Qasem Soleimani in 2020, only for the actual response to be calibrated, telegraphed in advance, and designed to allow face-saving rather than escalation. The critical question now is whether whoever consolidates power in the coming weeks possesses the political sophistication to thread that needle again, or whether genuine grief, nationalist fervor, and factional competition push toward something more reckless.
The economic ripple effects are already measurable. Bloomberg Economics published a projection Monday that the Iran conflict will keep global interest rates up to half a percentage point above pre-conflict baselines through 2028 — a figure that translates, on a 30-year U.S. mortgage, to roughly $90 to $100 more per month on a $400,000 loan. Multiplied across every government carrying debt and every household borrowing at elevated central bank rates, the effect amounts to a structural tax on economic activity that compounds over time.
The Hormuz convoy illustrated precisely why the energy dimension of the conflict commands such attention. Ten Japan-linked ships, including six supertankers carrying 12 million barrels of crude oil, moved through the Strait simultaneously in one of the largest coordinated convoy movements since the crisis began. The decision by major Japanese shipping interests to move in such a large, synchronized group signals a perceived risk environment in which insurance costs alone begin distorting global trade. A cargo ship attacked off the Yemen coast over the weekend added another layer: Houthi forces, maintaining their connection to Iran's regional network, continue to threaten commercial shipping through the Red Sea, stacking that risk on top of the Hormuz premium.
A sanctions angle complicates the diplomatic picture further. Data published recently showed that sanctioned nations moved $100 billion in cryptocurrency in 2025 — an eightfold increase — reflecting how quickly Iran and other sanctioned states have developed alternative financial infrastructure that insulates them from traditional pressure. Against that backdrop, Iran's reported offer to provide Europe with air conditioners in exchange for sanctions relief reads as a signal that pragmatic factions still exist within the government alongside the hardliners demanding revenge — a duality that will define the crisis's trajectory over the next two to three weeks.
