Here's an eye-opening article about the parlous state of Iran's economy after two months of battering by American and Israeli forces. Spoiler: it's substantially worse than I thought.
At least a million jobs have been lost directly due to the war, and 10-12 million - almost half of Iran's labour force - are at risk from the ripple effects.
Although Israel claims to have landed precision strikes on Iran's paramilitary Revolutionary Guard facilities early in the war, in fact their air strikes destroyed or damaged some 20,000 civilian factories, hobbling about 20% of the country's manufacturing capacity, particularly in the essential pharmaceuticals, petrochemicals, aluminum, cement and steelmaking sectors. This has crippled Iran's main non-oil exports, and raised domestic prices for everything from plastics and pipes to fabrics, packaging and construction materials. There was little or no military targeting involved in this; this was an opportunistic Israel gleefully moving to incapacitate its arch-enemy's economy under cover of US bluster, while it thought it could get away with it.
Iran's internet has been largely shut down since the start of the war (or even before, during the domestic protests that preceded it), gutting all the small- and medium-sized businesses that rely on online sales.
Before the war, Iran made about $98 billion in exports, just under half of it from oil. A good proportion of that is now gone, mainly due to the US blockade on exports, with no end in sight (although actually about half of Iran's non-oil trade goes overland and through Caspian Sea ports, and not through the blockaded Strait of Hormuz).
Pre-war, Iran relied substantially on the United Arab Emirates for up to a third of its imports. Since the US strikes, it has had to retaliate however it can, including strikes on UAE, leading that country to cut off all trade with Iran. No more imports.
The city of Kashan, where most of Iran's lucrative carpet production was centred, has all but closed down. Exports have plummeted and domestic sales petered out. Prices for synthetic fibres have surged by 30-50%, largely due to ongoing hits on Iran's petrochemical facilities.
Most new construction has ground to a halt, with priority going to the reconstruction of essential infrastructure. The price of iron sheeting has more than doubled. Savings of individuals and companies alike are starting to run out, those that had any.
Even with all that litany of grimness, Iranian officials are however still trying to reassure the public that the country can withstand all the economic pain. Certainly, if any country could, it is Iran. After decades of sanctions, the country has built up a lot of resilience, and is well-prepared for "worst case scenarios". It maintains large reserves of vital supplies, and even resources like electrical machinery, cement, iron and steel, for just such an emergency. The US has clearly been shocked by how resilient Iran has proved, although a bit more inquiry and less hubris could easily have alerted them to that.
Such reserves and resilience are not, of course, unlimited. While it is thought that Iran could still bounce back once the war ends, that would largely depend on whether international sanctions were lifted, and that in turn depends on a whole load of other things, things that are currently unknown. Whether Iran can outlast the United States - which has its own constraints and determining factors - is an open question.
