MOPS Explained: Why Singapore Prices Set Your Pump Cost

Every Tuesday, oil companies in the Philippines file a notice with the Department of Energy announcing whether pump prices will rise, fall, or stay the same the following day. Drivers see the headline figure — "gasoline up ₱0.50 per liter" — and move on. What almost nobody talks about is where that number actually comes from: a pricing benchmark published out of Singapore called the Mean of Platts Singapore, or MOPS.

Understanding MOPS will not let you avoid a price hike. But it will tell you, days in advance, whether one is likely — and that knowledge is worth something if you drive for a living or manage a fleet.

What MOPS Actually Is

S&P Global Commodity Insights (formerly Platts) is a price-reporting agency. Several times each trading day, its assessors survey actual transactions and bids in the Singapore refined-products market — the largest trading hub for petroleum in Asia — and publish benchmark prices for specific fuel grades: gasoline (92-RON, 95-RON), gasoil (diesel), kerosene, and others.

The "Mean" is a time-weighted average of those assessments across a published trading window. Singapore is used because it is the region's pricing center: refineries from South Korea, Japan, India, and the Middle East all converge on the Singapore spot market to sell products destined for Southeast Asia.

The Philippines imports most of its refined fuel. Batangas and other domestic refineries cover only a fraction of national demand. The rest arrives as finished product — largely priced off Singapore. MOPS is therefore not an abstraction; it is a direct input cost for every barrel of gasoline or diesel that lands at a Philippine terminal.

How MOPS Travels From Singapore to Your Tank

The journey from a Singapore price screen to a Philippine pump involves four layers.

Layer 1: The MOPS Average

Oil companies look at the average MOPS for the prior two weeks (the exact window varies by company but the DOE's standard reference period is roughly two weeks). If the 95-RON gasoline MOPS average rises over that window, importers paid more per barrel. If it falls, they paid less.

Layer 2: Foreign Exchange

MOPS is quoted in US dollars per barrel. Philippine importers buy using dollars, so they must convert at the prevailing USD-PHP exchange rate. A weakening peso amplifies a MOPS increase; a strengthening peso softens it. This is why pump prices sometimes move even when crude oil is flat — the exchange rate is doing the work.

A ₱1 depreciation against the dollar adds roughly ₱0.50 to ₱0.60 per liter to the landed cost of imported fuel, depending on the product and the period.

Note: that figure is a qualitative industry rule of thumb widely cited by DOE briefings; actual impact varies by company and import volume.

Layer 3: Freight, Insurance, and Terminal Costs

Landed cost is not just MOPS-times-exchange-rate. Add freight from Singapore or the refinery of origin, marine insurance, demurrage (port waiting fees), wharfage, and terminal throughput charges. These are relatively stable but they are real costs, and they are baked into every liter before a single tax is added.

Layer 4: Taxes, Margins, and the Pump Price

On top of landed cost, the government collects:

• Excise tax — fixed per liter under the TRAIN Law (₱10.00/L for gasoline, ₱6.00/L for diesel as of current rates).
• Value-Added Tax (VAT) — 12%, applied to the sum of landed cost plus excise tax.
• Local business tax — varies by city or municipality.

After taxes, oil companies add their distribution cost and dealer margin. The dealer margin is what funds the gasoline-station operator. The total of all these layers is the posted pump price you see on the signboard.

You can see the grade-by-grade breakdown of any given week's adjustment on the live fuel price page or dig into specific grades on the diesel price tracker and gasoline price tracker.

Why the Two-Week Lag Matters

Because Philippine oil companies use a trailing average — not today's MOPS — pump prices always lag the spot market by roughly one to two weeks. This creates two practical implications for drivers.

When MOPS is rising, pump prices have not yet fully reflected the increase. You can expect further hikes in the coming adjustment cycles. Filling up earlier in the week — before Wednesday's adjustment takes effect — can save a few pesos per liter.

When MOPS is falling, the relief has not fully arrived yet either. Waiting a week before a major fill-up may net a lower price. For fleet managers buying hundreds of liters at a time, the timing difference is not trivial.

This lag is also why a single day's crude-oil crash rarely produces an immediate pump-price cut. The market needs several days of sustained lower MOPS before the two-week average moves enough to trigger a reduction.

The Difference Between Crude Oil and MOPS

This distinction trips up most news coverage. Crude oil (Brent, WTI, Dubai) is the raw material. MOPS is the price of the finished product — already refined into gasoline or diesel. The two are closely correlated but not identical.

Refinery margins (called "crack spreads") sit between crude and refined-product prices. When refineries are running at high utilization globally, crack spreads widen and MOPS rises faster than crude. When demand for jet fuel collapses (as it did during the pandemic), refinery economics shift, and different grades move differently. This is why diesel and gasoline do not always change by the same amount in a given week's price adjustment.

What Drives MOPS Week to Week

• Regional refinery outages — a fire at a South Korean or Singapore refinery tightens regional supply and pushes MOPS up.
• Seasonal demand — driving season in the Northern Hemisphere lifts gasoline MOPS from May to September.
• OPEC+ output decisions — these affect crude, which in turn pressures refinery economics and refined-product prices.
• China's fuel exports — when Chinese state refineries export surplus diesel to Southeast Asia, it softens regional gasoil MOPS.

None of these factors are visible from a Philippine highway, but they all appear — with a one-to-two-week delay — at the pump.

How to Use This Knowledge Practically

You cannot trade MOPS futures. But you can monitor indicators that lead Philippine pump prices by roughly a week.

The DOE publishes a weekly oil-industry update that references MOPS movements. Reading it takes about five minutes. If the update shows MOPS averaging higher than the previous week, budget for a price hike at the next adjustment. If it shows MOPS sliding, you have reason to expect a rollback.

For private drivers, this mainly informs when to fill up — earlier or later in the week. For fleet operators and transport network companies, it informs procurement decisions: whether to top up company tanks before Wednesday or hold off.

The Part No Benchmark Can Control

MOPS explains the variable cost of fuel. It does not explain everything on your fuel bill.

The fixed excise tax means that even when MOPS hits a multi-year low, Philippine pump prices have a hard floor set by law. Conversely, when MOPS spikes, the percentage impact on the pump price is dampened because the fixed taxes are a large share of the total. This is the structural reality of the current tax regime, and it is worth keeping in mind when comparing Philippine pump prices to neighbors like Malaysia or Indonesia, where fuel subsidies create an entirely different pricing architecture.

What MOPS does give you is transparency. The benchmark is published, the methodology is documented, and the DOE requires oil companies to show their computation. A pump price that diverges significantly from what MOPS and the exchange rate would predict is a price worth questioning — and reporting to the DOE's Oil Industry Management Bureau.
