Iran says it is banning cryptocurrency mining until September 22 after a series of power blackouts across major cities
as well as increased manufacturing and a drop in hydroelectricity supply — for blackouts that are playing havoc with businesses and daily life.’ https://www.bloomberg.com/...
Context & Ripple Effects
This is Iran's second crackdown in five months: in January, authorities blamed legal and illegal mining for nationwide blackouts and shut down a large licensed Chinese-Iranian operation (the January shutdown), following an earlier 2019 grid warning and machine seizure. Unlike those actions, this ban is time-boxed until September 22 and pairs mining with two other cited causes — increased manufacturing and a seasonal drop in hydroelectricity supply.
The move also fits Iran's longer pattern of restricting crypto when macro pressure builds, from the central bank's 2018 prohibition on bank dealings (banking ban) to today's power-based suspension.
First-order effects
- Licensed miners, including foreign-operated facilities like the January-shut Chinese-Iranian farm, must power down through September 22, while illegal operations face continued enforcement during the blackout season.
Second-order effects
- Mining operators are pushed further off-grid or underground, complicating the licensing regime Tehran built to capture mining revenue, and hardware suppliers lose a sanctioned market for months.
Third-order effects
- If seasonal power shortfalls keep recurring, Iran's approach converges with Russia's later model of calendar-based regional mining bans (Russia's winter ban in ten regions) — governments treating mining load as dispatchable demand to be switched off rather than a fixed industry.
The trend: State grids are starting to treat crypto mining as curtailable peak-load capacity, banning it on a seasonal schedule instead of outlawing it outright.
