Oil price range on August 1, 2026

Type of oil	Lowest	Highest	Amplitude difference
WTI oil	$81.21 per barrel	$86.87 per barrel	$5.66
Brent crude oil	$84.62 per barrel	$91.36 per barrel	$6.74

The gap between Brent and WTI crude oil prices at the time of this update has narrowed to just $1.13 per barrel, a significant reduction from the $2.98 per barrel mark on July 31st. This reflects the fact that WTI crude oil is rising faster than Brent crude oil.

Despite the upward trend, the wide trading range indicates that the crude oil market remains highly volatile. The price on August 1st is data at the time of update and is not necessarily the official closing price of the session.

Note the increase in WTI oil prices.

The source data table shows WTI oil prices rising by $3.21, or 3.84%. However, compared directly to the $84.03/barrel price on July 31st used in the previous report, the day-to-day increase is $2.77, or 3.30%.

The discrepancies may arise from the data platform using a different reference price, closing date, or contract term. This article uses a direct comparison between the prices on July 31st and August 1st to ensure consistency.

Forecast for the next fuel price adjustment period.

According to the usual price adjustment schedule, fuel prices are announced every Thursday. Following the July 30th adjustment, the next one is expected to take place on Thursday, August 6th, 2026.

If the same timeframe as the most recent period continues to apply, the new price could take effect from 3 PM on August 6th. The official timing and amount of the adjustment still need to be announced by the regulatory authority and the leading businesses.

The more than 3% increase in WTI oil and the continued rise in Brent oil on the first day of August could put further pressure on domestic gasoline prices if this trend continues.

However, it is not possible to conclude from a single day’s developments that retail prices will continue to rise in the next period. The base price is calculated based on the average price of petroleum products in the world market between two price adjustment periods, along with exchange rates, taxes, fees, and other constituent costs.

WTI and Brent crude oil prices primarily serve as trend indicators. Domestic prices for E5 RON 92 and E10 RON 95 gasoline, diesel fuel, and kerosene also depend on the specific developments of each refined product in the international market.

Notable scenarios ahead of August 6th

If global oil and refined product prices continue to rise in the coming sessions, domestic retail prices could face further upward pressure.

Conversely, if the current upward trend is short-lived and international prices quickly cool down, the adjustment may be narrowed or some items may remain unchanged.

Following the sharp increase on July 30th, the likelihood of a correction in the next cycle needs to be assessed across the entire cycle, rather than based on a single oil price at a single point in time.
