The reduction brought domestic fuel prices close to pre-war levels, according to reporting on the July 4 adjustment.
For a typical private car with a 50-liter tank, the cut will save drivers about 35 to 40 yuan per fill-up, depending on the grade of gasoline and local rounding. Using the reported 950-yuan-per-tonne gasoline cut and an approximate conversion of about 1,350 liters per tonne, the implied reduction is roughly 0.70 yuan per liter.
The reductions were linked to a decline in international oil prices as Iran-U.S. peace talks eased concern about supply disruption through the Strait of Hormuz. Previously, the Iran conflict had strained global energy supplies and driven oil prices sharply higher, so de-escalation directly enabled the price relief. China's pricing mechanism adjusts domestic retail caps every 10 working days in line with changes in global crude oil prices.
South Korea announced on June 26, 2026 that it would lower its fuel price cap for the first time since introducing the emergency system in March. Finance Minister Koo Yun-cheol said the seventh cap would be lower than the previous one, as part of efforts to curb inflation pressure. The government lowered price ceilings on fuel products to reflect the recent decline in global crude oil prices.
The reported capped supply prices (the maximum prices refiners can charge gas stations) were:
This was a cut of 150 won per liter from the previous cap. The government also vowed to freeze electricity and gas rates in the second half of the year to further tame inflation. South Korea had earlier expanded fuel tax breaks to 15% for gasoline and 25% for diesel through the end of July in response to Iran-related energy-market pressures.
By the first week of July, pump prices had already fallen: the average national gasoline sales price at gas stations was 1,952.1 won per liter, down 55.7 won from the previous week.
Taiwan's state-owned oil supplier CPC Corp. announced on June 27, 2026 that it would cut its domestic gasoline and diesel prices to respond to a fall in international crude oil prices. The cuts:
After the decision, CPC recommended retail prices of NT$30.4 per liter for 92-octane, NT$31.9 for 95-octane, and NT$33.9 for 98-octane unleaded gasoline. The recommended price for premium diesel fell to NT$29.5 per liter. The new prices were effective from midnight on Monday, June 29 through July 5.
Taiwan had earlier expanded fuel commodity tax reductions to 50% as part of broader efforts to shield consumers from higher global energy costs.
| Economy | Effective Date | Gasoline Cut | Diesel Cut | Mechanism |
|---|---|---|---|---|
| China | July 4, 2026 | 950 yuan/tonne (~0.70 yuan/L) | 915 yuan/tonne | NDRC retail price cap reduction |
| South Korea | June 26, 2026 | Supply cap set at 1,784 won/L | Supply cap set at 1,773 won/L | Petroleum price ceiling reduction; fuel tax cuts extended through July |
| Taiwan | June 29, 2026 | NT$1.0/L cut | NT$0.8/L cut | CPC Corp. price adjustment; commodity tax cuts at 50% |
The common thread across all three economies is a sharp decline in global crude oil prices. After months of elevated prices driven by the Iran conflict and fears of Strait of Hormuz disruption, Iran-U.S. peace talks in mid-2026 began to ease supply concerns. This allowed governments in East Asia — which had previously raised price caps, expanded subsidies, and cut taxes to shield consumers from soaring energy costs — to begin rolling back some of those measures and pass lower global prices through to drivers.
South Korea's Finance Minister Koo Yun-cheol explicitly linked the cap reduction to stabilization in the Middle East situation, saying the government would keep the cap system in place until consumer prices fully stabilize. China's NDRC similarly cited changes in international crude oil prices as the basis for the adjustment.
