Taiz, a city of roughly one million people, is experiencing the kind of siege that destroys civilian economies in weeks. The Houthi military offensive — which has seized more than 1,000km of territory over the past month and now controls the Bab al-Mandab strait — halted at Taiz but has not retreated. Meanwhile, Saudi-backed Yemeni government forces have closed routes into the city, ostensibly for military reasons, creating a pincer that denies both food and fuel to the population trapped inside. The numbers are stark. Wheat flour prices have more than doubled. Petrol prices have more than doubled. The UN World Food Programme says 800,000 people — four-fifths of the city — have been cut off from vital assistance. Schools, universities, and public institutions closed on 4 October. The city's economic life has effectively stopped. The extraction pattern here is textbook dual-siege economics. Two armed factions — the Houthis and the Yemeni government — are competing for territorial control of a strategic crossroads city, and the entire cost is borne by the civilian population. Neither side is paying the price of the war it is waging; both are externalising the cost onto the people of Taiz through supply denial, price inflation, and physical danger. Residents like Ali Abdulsamed, a mobile-repair shopkeeper, are selling personal assets — his wife's gold ring — to buy a single bag of flour. Taiz's strategic significance makes resolution unlikely. The city sits at the crossroads between north and south Yemen; if it falls to the Houthis, Aden — the government's seat — is functionally cut off. This makes Taiz a prize neither side can concede, which means the siege dynamic has no natural off-ramp. The government announced a counteroffensive two weeks ago, but local residents like schoolteacher Rawa describe a city that feels like it is preparing for a long, closed-in war, not a liberation. The humanitarian architecture that existed before the offensive is now severed. The 2022 UN-brokered ceasefire had frozen frontlines for four years, creating fragile but functional supply corridors. The Houthi offensive last month shattered those corridors entirely. WFP access to Taiz is blocked. Roads south — the traditional evacuation route — are closed. The city has become a sealed container with dwindling contents. The broader regional dimension intensifies the problem. The Houthis and Saudi Arabia are now trading direct strikes — Houthi attacks on Riyadh airport, Saudi strikes on Sana'a. This escalation ladder makes Taiz a secondary theatre in a regional confrontation, reducing the chances of localised humanitarian access even further. When wars become proxy contests, civilian corridors are the first casualty. What Taiz illustrates is the fundamental asymmetry of modern siege warfare: the factions that create the siege bear none of its costs, while the population that bears all the costs has no agency over the siege's duration or resolution. Every day the siege continues, the civilian economy degrades further, savings are consumed, and the population becomes more dependent on external aid that cannot reach them.
