China's Gasoline and Diesel Inventories Fall to Multi-Year Lows, Rising Risk of Export Restrictions
nashnova research
China's gasoline stocks hit their lowest since 2022 and diesel stocks touched a 15-month low, raising the risk that Beijing will tighten refined-product export quotas in Q4 — a move that would squeeze supply for buyers across Asia.
How far have inventories fallen?
Data from JLC — a Chinese consultancy that collects figures directly from state-owned fuel distributors in each province — shows gasoline stocks fell 2.9% last week to the lowest since 2022.
Diesel stocks dropped 2.4%, hitting a 15-month low.
This means → both major fuel products are drawing down in tandem, and the domestic supply gap is widening. China's government publishes no official inventory figures, making JLC's data the market's only window.
Why do falling inventories threaten exports?
Beijing controls refinery exports through a quota system. One precondition for allowing refiners to resume and increase exports has been maintaining high domestic inventories.
In plain terms = if stocks are comfortable, refiners get the green light to sell abroad; once stocks tighten, that door can close.
Energy Aspects analyst Sun Jianan estimates the risk is rising that Beijing will cap clean-fuel exports at roughly 1.2 million tonnes per month in Q4.
This reflects a regime where quotas are not fixed numbers — they flex with domestic supply and demand, and inventory is the key switch.
Is there a precedent for export curbs?
When the US–Iran war broke out, Beijing quickly tightened fuel exports, leaving Asian buyers scrambling for supply.
Restrictions were later eased. Customs data show combined exports of gasoline, diesel, and jet fuel rebounded to 2.55 million tonnes in July.
This means → Beijing's playbook is "tighten when tight, loosen when loose." The current inventory slide is pushing the needle back toward "tighten."
What is going wrong on the crude-supply side?
Strait of Hormuz transit volumes remain well below pre-war levels. Saudi Arabia's East–West pipeline recently shut, threatening Red Sea export routes.
Houthi ground advances in Yemen are adding further uncertainty to Red Sea shipping.
In plain terms = three major channels for moving Middle Eastern crude — the strait, the pipeline, and the Red Sea — are all disrupted at once, squeezing China's supply from multiple directions simultaneously.
What trouble are independent refiners in?
China's independent refiners — known as "teapot refineries" — have lost access to Iranian crude due to US sanctions enforcement.
They are turning to African and Latin American alternatives, which has driven up premiums on those grades.
This means → if conditions worsen, teapots may be forced to cut run rates in the coming weeks, further shrinking domestic fuel output and creating a negative feedback loop: tighter supply → lower inventories → harder to export.
What to watch next?
The key marker: whether inventories stabilize before Q4.
If drawdowns continue, tighter export quotas are near-certain. If stocks level off, the current export pace can hold.
This reflects a shift for the Asian refined-products market: China's inventory data have replaced quota announcements themselves as the leading indicator for the supply outlook.
