For rationing to be declared it comes down to what the government officially calls it. The president previously said rationing might have to happen. If that's what they call it, regardless of what actually happens, the option resolves YES.
I'll not participate in the market in case the actual numbers get fuzzy.
Update 2025-11-20 (PST) (AI summary of creator comment): The market resolves based on official government terminology, not actual water management actions. Reduced water pressure in Tehran has already occurred, but this does not count as rationing unless the government officially calls it "rationing".
@AlanTennant keep in mind it's about what they call it. The water pressure in Tehran has already been reduced but "rationing" was only announced as a possibility
