China's Refinery Output Falls to Nearly Four-Year Low as Crude Imports Hit Eight-Year Trough
Miles Bennett
China's May refinery throughput plunged 9.1% year-on-year to its lowest since August 2022, after a near-total shutdown of Persian Gulf shipping dragged crude imports to an eight-year low — but the deeper question is whether electrification has permanently capped fuel demand even after supply returns.
How steep was the refinery drop?
May throughput hit 53.72 million tonnes, down 9.1% year-on-year — the lowest since August 2022.
State-owned refinery utilisation averaged just 66.3%. This means → a third of capacity sat idle, the worst reading since the dataset began in late 2021.
The direct trigger: the Strait of Hormuz (the chokepoint linking the Persian Gulf to open sea, carrying roughly a fifth of global crude) was virtually shut, pushing crude imports to an eight-year low.
Will reopening the strait fix things?
A Hormuz reopening deal is in place, yet GL Consulting forecasts full-year 2026 refinery output will still fall about 5%.
This reflects a structural shift: rapid electrification of China's transport sector is permanently compressing gasoline and diesel demand.
In plain terms = the shipping disruption is a short-term shock; the real headache for refiners is that even when crude arrives, the fuel they produce may not find buyers.
How did other industrial outputs fare?
Aluminium hit a record: May output reached 3.89 million tonnes, up 1.7% year-on-year, as China capitalised on Middle East supply gaps to expand export share.
That tailwind may fade — once the US-Iran deal restores regional supply, Chinese aluminium exports could shrink, and weak domestic demand plus capacity ceilings add further pressure.
Coal output fell 1.7% to 397.2 million tonnes after tightened safety inspections following a major accident in Shanxi, China's largest coal-producing province. The disruption there is expected to linger.
What signals are power and steel sending?
Power output rose 4.2% year-on-year in May; El Niño-driven heat pushed southern China's peak load roughly one month earlier than usual.
Steel output fell 2.7% to 84.36 million tonnes — the property crisis keeps dragging on demand, while the Shanxi accident lifted coking-coal costs and squeezed mill margins further.
This means → power demand is weather-supported, steel demand is property-dragged — the two lines point to very different readings of economic temperature.
What does this mean for the broader economy?
Bloomberg Economics notes that Chinese consumer spending has contracted for the first time since the pandemic, and investment is deteriorating.
If the US-Iran deal fully restores energy flows, it would ease one key constraint on China's economy — but the foundation remains fragile.
In plain terms = whether refinery capacity restarts as imports recover is a critical demand-side litmus test. The question is no longer "is there enough crude?" — it is "even with crude, can refiners run profitably?"
