Bunker markets and what they mean for your Philippine cargo fixture

On March 13, 2026, the price of VLSFO bunker fuel in Singapore reached $1,120.50 per metric ton.1 Four weeks earlier, that same fuel had been trading at $521.50. By the time that move had fully transmitted to Manila bunker prices, Philippine inter-island operators had already absorbed the cost gap in their voyage margins — with no immediate mechanism to recover it from charterers.

Bunker fuel is the single largest variable cost in Philippine inter-island shipping, typically accounting for 40 to 50 percent of total voyage expenditure. A $600 per metric ton swing — the distance between a calm market and the March 2026 peak — on a voyage consuming 400 metric tons of fuel is a $240,000 difference. That is not an accounting problem. It is an existential one for operators without a framework for managing it.

What makes this problem specific to Philippine inter-island operators is not the global price spike itself. It is a compounding cost structure we call the Three-Layer Premium: global crude volatility, the Singapore hub concentration effect, and a domestic regulatory lag that prevents operators from passing fuel costs to charterers in real time. Each layer is a distinct source of risk. Together, they mean that when bunker prices move, Philippine inter-island operators absorb more of the move, for longer, than almost any other class of commercial ship operator in the world.

A $600 per metric ton swing on a 400-tonne voyage is a $240,000 difference. That is not an accounting problem. It is an existential one.

The price a vessel owner pays at a Manila berth is not a local number. It is the end result of a four-stage price chain, and each stage adds cost and time lag. Understanding that chain is the prerequisite for managing it.

1. 01Crude oil benchmark. Global bunker prices are anchored to crude oil. Brent crude is the primary reference. At $60 to $70 per barrel — the pre-crisis analyst consensus for 2026 — VLSFO typically prices in the $400 to $500 per metric ton range. At $100 to $115 per barrel, the EIA's Q2 2026 peak forecast,6 expect $700 to $900 per metric ton for VLSFO under normal refinery conditions, and higher during a supply shock.
2. 02Singapore refining and the MOPS benchmark. Singapore is the world's largest bunkering port and the refining hub that supplies most of Asia. The Mean of Platts Singapore (MOPS) price is the index against which Philippine bunker suppliers price their product. When Singapore prices move, Manila prices follow — typically with a four to six week lag through the physical supply chain.1
3. 03Manila supplier margin. Philippine bunker suppliers apply a delivery margin over MOPS to cover logistics, storage, and local handling. In a normal market, Manila VLSFO trades at a $60 to $100 per metric ton premium over Singapore. In a tight market, that premium widens significantly: during the March 2026 crisis, Manila HSFO reached $1,560 per metric ton while Singapore was at $1,120 — a $440 premium that reflected regional supply constraints.2
4. 04Regulatory rate recovery. Unlike international deep-sea carriers who adjust BAF (Bunker Adjustment Factor) monthly against live price indices, Philippine inter-island operators must obtain MARINA approval before passing fuel cost increases to charterers. In March 2026, MARINA authorized a surcharge of up to 20 percent of base fare.4 The time between a price spike and approved cost recovery is where voyage margins are destroyed.

International shipping analysts track global bunker prices. What they do not track is the compounding structure that makes those prices functionally different for Philippine inter-island operators than for a Maersk vessel calling Singapore. We describe this as the Three-Layer Premium. Each layer is a distinct source of cost and risk. They compound.

Layer 1: Global crude volatility. Analyst consensus at the start of 2026 put Brent crude at $57 to $67 per barrel for the full year.6 By March 2026, Brent was averaging $103 per barrel — a 53 to 81 percent premium over those base forecasts. The trigger was the escalation of the ongoing Israel-Iran conflict into direct US and Israeli military strikes on Iranian infrastructure, followed by Iran's closure of the Strait of Hormuz on February 28, 2026. The Hormuz chokepoint carries 15 million barrels per day of Gulf crude exports, roughly 17 percent of global supply.10 Saudi Arabia's East-West pipeline — the only overland bypass — has spare capacity of only 1 to 2 million barrels per day, nowhere near enough to substitute. A Philippine operator with no crude exposure and no hedging instrument absorbs this entire swing as a direct fuel cost.

Layer 2: The Singapore hub premium. In normal conditions, Singapore trades at a modest premium over Atlantic bunkering hubs. During the March 2026 supply shock, Singapore VLSFO priced at $250 to $320 per metric ton above Rotterdam and Houston.8 A European operator bunkering in Rotterdam paid approximately $780 per metric ton for VLSFO during the same week a Philippine operator paid $1,120 in Singapore. The geographic concentration of Asia-Pacific refining capacity means that any disruption to Middle East supply flows hits Singapore first and hardest — and Manila is priced off Singapore.

Layer 3: The regulatory lag. International carriers adjust BAF monthly against live MOPS indices. The adjustment is contractual: charterers know the formula and the timing before a voyage begins. Philippine inter-island operators operate under MARINA-regulated tariff frameworks. When bunker prices spike, operators must file for a surcharge, MARINA must review and approve it, and the approved surcharge is capped — MARINA Circular 2026-10 authorized a maximum 20 percent adjustment on base fares and cargo freight rates.4 In March 2026, when Manila VLSFO had doubled in six weeks, 20 percent of a base freight rate set at 2025 fuel prices was not a recovery mechanism. It was a partial offset on a structural loss.

On January 1, 2025, MARINA Advisory No. 2024-35 came into effect, mandating that all domestically registered Philippine vessels operating in Philippine waters use fuel with a sulfur content of 0.50 percent or below.3 This aligns Philippine domestic shipping with the IMO 2020 global sulfur cap. The timing matters because it permanently removes a cost management tool that international deep-sea carriers use as a hedge: the scrubber strategy.

Under the global sulfur framework, a ship fitted with an exhaust gas scrubber can continue burning high-sulfur fuel oil (HSFO), which trades at a significant discount to VLSFO. The VLSFO-HSFO spread averaged $65.60 per metric ton in 2025, down from $98.90 in 2024 and $120.90 in 2023 as VLSFO supply increased.7 But during the March 2026 supply shock, that spread widened sharply back toward $100 per metric ton as VLSFO was disproportionately affected by the Middle East disruption.

A scrubber-fitted international carrier operating on Manila-adjacent routes in March 2026 paid approximately $656 per metric ton for HSFO in Singapore — while an equivalent Philippine inter-island operator without a scrubber option paid $718 to $1,120 per metric ton for VLSFO.1 Philippine domestic operators cannot use the HSFO pathway regardless of scrubber economics. The MARINA sulfur mandate forecloses it entirely.

Because Manila prices track Singapore MOPS with a four to six week lag through physical supply logistics, Singapore spot prices function as a leading indicator for what Philippine operators will pay next month. This is not a trading insight — it is a planning tool, and it is freely available daily on the Ship and Bunker price pages.1

The March 2026 data demonstrates the window. Singapore VLSFO was trading at $486 per metric ton in mid-February and $521.50 on February 27 — the day before the Hormuz disruption began.1By March 13 it had reached $1,120.50. An operator monitoring Singapore daily from late February would have seen prices climbing sharply and had three to four weeks before that move reached Manila prices at full force.

Three to four weeks is enough time to:

1. 01Prepare and pre-position a MARINA surcharge filing. The regulatory process takes time; starting it when Singapore prices signal a major move means the approval arrives closer to when Manila prices peak, not weeks after.4
2. 02Open conversations with charterers about upcoming freight rate adjustments. Showing charterers Singapore price data gives a factual basis for the discussion before Manila prices confirm the move.
3. 03Assess voyage scheduling and optimize fuel consumption. Speed reductions of two to three percent reduce fuel burn by approximately six to nine percent — meaningful savings when prices are elevated and margins are under pressure.
4. 04Evaluate pre-purchasing fuel at current prices if storage allows and the forward price trajectory is clearly upward. This is not formal hedging, but it achieves a similar result for operators with the facility to execute it.

The intra-Asia container market provides independent confirmation that Singapore bunker moves do transmit regionally and quickly. In the fortnight to March 30, 2026, average intra-Asia container rates rose 10 percent as Singapore bunker costs flowed through freight pricing across the region.9 Philippine inter-island rates will follow the same dynamic; the question is whether operators are positioned to absorb the timing gap or not.

The structural disadvantages of Philippine inter-island operators relative to international carriers — no indexed BAF, no HSFO pathway, MARINA approval lag — are real. But they are not new, and they are not unmanageable. The operators who absorb the least cost during bunker spikes are those who have embedded cost-recovery mechanisms before the spike arrives, not those who react to it.

1. 01Include a fuel cost adjustment clause in charter parties. Reference Ship and Bunker Manila VLSFO as the index.2 Set a base price and a trigger threshold above which the clause activates. This makes bunker cost recovery a contractual mechanism rather than a MARINA filing for every price movement. Charterers who understand bunker economics will accept this clause; its absence shifts all fuel risk to the operator.
2. 02Maintain a standing MARINA surcharge dossier. Build and keep current the documentation package required for a MARINA fuel surcharge filing — current tariff schedules, recent bunker invoices, route-specific fuel consumption data. When prices spike, you file within days. The dossier requirement is constant; the urgency is not predictable.4
3. 03Set a Singapore price alert at your voyage break-even. Calculate the Singapore VLSFO price at which your current freight rates stop covering voyage costs. When Singapore crosses that threshold, the four to six week clock on Manila price transmission starts. That is your planning window, not a warning to react to.1
4. 04Negotiate volume terms with bunker suppliers. The $758.66 million Philippine bunker market in 202411 is large enough that suppliers compete for anchor accounts. Volume agreements — even informal ones with committed monthly quantities — provide pricing stability that spot purchases do not.
5. 05Model your voyage economics at three fuel price scenarios. Use current price, Singapore-signaled price (four to six weeks forward), and a stress scenario of current plus 40 percent. A voyage that is marginally profitable at current prices and loss-making at stress scenario should not depart without rate protection in place.

The operators who absorb the least cost during bunker spikes are those who have embedded cost-recovery mechanisms before the spike arrives.

Our assessment of Philippine bunker costs through the remainder of 2026 is built on three scenarios. Each has distinct implications for inter-island cargo fixture economics. We state our view on each.

Base case: geopolitical normalization by mid-2026. If Hormuz flows stabilize and OPEC's additional production of 206,000 barrels per day absorbs part of the supply gap, Brent should retrace toward $75 to $85 per barrel in the second half of the year. Singapore VLSFO would settle in the $500 to $620 range, and Manila VLSFO would follow at $580 to $720 per metric ton — elevated relative to the 2025 average but manageable for operators with fuel clauses in their charter parties. We expect one additional MARINA surcharge window to be authorized before end-2026 under this scenario.

Elevated case: Hormuz disruption extends through Q3 2026. Wood Mackenzie has modeled potential crude prices well above $100 per barrel if Hormuz flows are not re-established.10 Under this scenario, Singapore VLSFO stays in the $700 to $1,000 range, and Manila prices could sustain above $800 per metric ton through Q3. The MARINA surcharge mechanism will be under pressure: a 20 percent adjustment on 2025-era base rates does not recover voyage margins when fuel costs have doubled. We expect MARINA to expand the approved surcharge window or introduce an indexed recovery mechanism under this scenario — but the approval lag means operators absorb several weeks of unrecovered cost regardless.

Structural trend: the calm market is not the normal market. Before the March 2026 spike, S&P Global's analyst Tolson had declared "peak VLSFO" — the thesis that VLSFO oversupply would structurally depress the fuel's price relative to crude.7 That thesis is correct in a stable market. The Ship and Bunker analyst poll published February 2026 forecast VLSFO averaging in the low $440s per metric ton for the year.1 Those forecasts were not wrong; the market was simply interrupted by a geopolitical event that had a 34 percent probability weight on Iranian-related crude risk factors. In Philippine waters, where operators cannot hedge into HSFO and where BAF is not contractual, a 34 percent probability event is not a tail risk. It is a planning input.

Beyond 2026, the direction of travel for Philippine domestic shipping is clear. MARINA's alignment with IMO frameworks has a demonstrated pattern: the IMO 2020 sulfur cap was adopted domestically in 2025, a five-year lag. A domestic CII-equivalent regulation — requiring vessels to report and improve carbon intensity — is a reasonable expectation for 2027 to 2030 on the same trajectory. This will add compliance cost to an already compressed fuel margin environment. Philippine inter-island operators who begin building carbon intensity data now, rather than when the circular arrives, will have a meaningful lead when it matters.
