Philippines Fuel Prices Could Surge Next Week: Gasoline Seen Rising by Up to ₱3 Per Liter
Filipino motorists are facing another possible increase in fuel prices next week, just days after pump prices were cut by more than ₱4 per liter.

The latest market estimates point to a gasoline increase of around ₱2.50 to ₱3.00 per liter, while diesel could rise by ₱3.75 to ₱4.25 per liter when the next adjustment takes effect on Tuesday, August 18.
The figures are still projections, not the final prices that motorists will see at fuel stations. The Department of Energy (DOE) is expected to announce the official adjustment after the full trading week is completed.
For Makon Financials readers, the important point is that the expected increase is being driven primarily by a sharp reversal in international oil prices and renewed uncertainty surrounding the Strait of Hormuz.
Philippines fuel prices could rise again on August 18
The timing is particularly significant because motorists only received a major price reduction this week.
Effective August 11, gasoline prices were reduced by about ₱4.70 per liter, while diesel fell by ₱4.30 per liter and kerosene by ₱4.88 per liter, based on the DOE’s announced adjustments.
That relief could prove short-lived.
After the first four trading days for the next pricing cycle, industry estimates indicated that gasoline could increase by ₱2.50 to ₱3.00 per liter on August 18. Diesel was projected to climb by ₱3.75 to ₱4.25 per liter.
Projected gasoline increase: ₱2.50–₱3.00 per liter.
Projected diesel increase: ₱3.75–₱4.25 per liter.
The ₱4.25 figure therefore refers to the upper end of the diesel estimate, not gasoline.
That distinction matters because some headlines describing a “₱4.25 fuel price hike” can easily be interpreted as a ₱4.25 increase in petrol. The available industry estimate is lower for gasoline.
Why Philippines fuel prices are turning higher again
The main pressure is coming from the international oil market.
Oil prices moved sharply higher as optimism surrounding a possible reopening of the Strait of Hormuz weakened. The strategic waterway has become one of the most important variables for the global energy market because a huge volume of crude oil and petroleum products normally passes through the area.
Gulf News reported that oil prices had risen for a second consecutive session on August 11 after Iran indicated that the Strait of Hormuz would remain closed unless the United States changed its position and accepted Tehran’s conditions for ending the conflict.
That immediately matters to the Philippines because local pump prices are heavily influenced by movements in international petroleum prices.
The Philippines does not determine gasoline and diesel prices independently of the global market. Local oil companies use international benchmarks, including Mean of Platts Singapore (MOPS), together with currency movements, taxes and other costs when determining domestic pump prices.
That means a sudden increase in international refined-product prices can eventually appear at Philippine filling stations.
The Strait of Hormuz is at the centre of the oil-price problem
The concern goes beyond the price of crude itself.
The Strait of Hormuz is a critical shipping route connecting the Persian Gulf with the wider global oil market. Gulf News cited maritime-industry tracker Kpler as estimating that the waterway normally handled roughly 125 to 140 vessels a day and carried around 20% of global oil supply before the conflict.
Even when physical supplies remain available, uncertainty over shipping can push oil prices higher because traders begin pricing in the possibility of delays, insurance costs, longer routes and reduced availability.
That is what makes the current situation particularly sensitive for countries such as the Philippines, which rely heavily on imported petroleum.
What is happening to global oil prices?
International crude prices have remained volatile throughout the conflict.
As of Friday, August 14, Brent crude was around $87.11 a barrel, while US West Texas Intermediate was around $81.35 a barrel, according to Gulf News. Brent had previously reached $88.91 in the cited trading period before easing.
The important issue for Philippine motorists is not simply where oil prices stand on one particular day.
The DOE’s weekly fuel-price mechanism looks at movements over the relevant trading period. Therefore, a late-week decline in crude prices may not be enough to completely erase the increase accumulated earlier in the week.
That is exactly the risk facing motorists ahead of the August 18 adjustment.
Why the final gasoline price could still change
The ₱2.50 to ₱3.00 gasoline estimate should not be treated as a confirmed pump-price increase.
It is an industry projection based on market movements before the end of the pricing week.
Victor Brooks reported that the estimates remained subject to changes in international oil prices and the peso-dollar exchange rate through the end of the trading week. Jetti Petroleum president Leo Bellas also said oil prices could ease during Thursday and Friday trading, although the decline might not be large enough to fully offset the earlier jump.
This is why the final number can be different from the early estimate.
If global oil prices fall sharply before the pricing calculation is completed, the expected increase could become smaller.
If prices rise further, the final adjustment could be higher.
The official announcement from the DOE therefore remains the number motorists should use when planning their fuel expenses.
What the increase could mean for Filipino motorists
A ₱2.50 to ₱3.00 increase may not sound enormous when viewed as a single litre.
The impact becomes more noticeable when multiplied across a full tank or repeated weekly refuelling.
For example, a driver buying 40 litres of gasoline would pay an additional:
₱100 if the increase is ₱2.50 per liter.
₱120 if the increase is ₱3.00 per liter.
For a 50-litre fill-up, the additional cost would be between ₱125 and ₱150.
Diesel users could face an even larger increase because the projected range is ₱3.75 to ₱4.25 per liter.
At 50 litres, that represents an additional ₱187.50 to ₱212.50 compared with the previous price.
These calculations represent only the projected increase, not the total price of the fuel.
Why businesses should pay attention to the fuel increase
The effect of higher fuel prices does not stop at petrol stations.
Transport companies, delivery businesses, logistics operators, construction firms, agricultural producers and other fuel-intensive businesses can face higher operating costs when diesel and gasoline prices rise.
For companies that transport goods across long distances, even a few pesos added to every litre can become significant over thousands of litres.
Those costs can eventually feed into the prices of goods and services if businesses cannot absorb them through their existing margins.
That is why fuel prices are closely watched by financial markets and policymakers. Petroleum is not just a transportation expense. It is an input into a much wider part of the economy.

Inflation is another concern
Higher fuel prices can create additional inflationary pressure through transportation and logistics costs.
A fuel-price increase does not automatically mean inflation will surge immediately. The effect depends on how large the increase is, how long elevated prices remain in place and whether businesses pass the additional costs to consumers.
But the timing is important.
The Philippines has already experienced significant fuel-price volatility in 2026, with international geopolitical developments repeatedly producing large movements in domestic pump prices.
The latest episode also demonstrates how quickly the situation can change.
Only days ago, motorists were receiving a major rollback of more than ₱4 per liter. Now the market is preparing for another possible increase.
The biggest risk is not the ₱3 gasoline increase itself
The more important question for the Philippine economy is what happens to international oil prices after August 18.
If the Strait of Hormuz situation improves and diplomatic negotiations gain momentum, oil prices could retreat again. That would reduce pressure on future Philippine fuel adjustments.
But if shipping disruptions continue or tensions escalate, the current projected gasoline increase could become only one part of a longer period of elevated fuel prices.
Gulf News reported that oil markets have repeatedly moved lower when hopes of a ceasefire and reopening of the strait improved, before jumping again when tensions increased.
That makes the outlook unusually dependent on geopolitical developments.
What motorists should expect on August 18
The next major date to watch is Tuesday, August 18, 2026.
Unless the market produces a significant reversal before the end of the trading week, Philippine motorists are expected to face another increase at the pump.
The current verified industry estimates are:
Fuel| Projected August 18 increase
Gasoline| ₱2.50–₱3.00/liter
Diesel| ₱3.75–₱4.25/liter
Kerosene| Final figure still subject to official announcement
The figures above should be treated as projections, not final DOE-approved adjustments.
The gasoline figure is particularly important because it corrects a potentially misleading interpretation of the headline numbers: petrol is not currently projected to rise by ₱4.25 per liter. The ₱4.25 upper estimate applies to diesel.
What comes next for Philippine fuel prices
The immediate direction of fuel prices will depend heavily on international oil prices, the peso-dollar exchange rate and developments around the Strait of Hormuz.
For now, the expected August 18 increase represents a reversal of the substantial relief motorists received on August 11.
The final adjustment will only become clear once the DOE completes its assessment of the full trading period.
For Filipino consumers and businesses, however, the message is already clear: fuel-price volatility remains a major financial risk.
A few days of falling international oil prices can produce a large rollback at Philippine pumps. A sudden geopolitical shock can reverse that move just as quickly.
