Public anger over pump prices is again colliding with the oil industry’s reliance on global pricing norms, with Chevron Philippines president Pongtorn Tangmanuswong defending “replacement cost” as key to keeping fuel flowing.
He framed the case with a simple analogy: sell gold bought at $100 when the market is at $150, and demand will surge, inventories will thin, and restocking becomes untenable. “This replacement costing is the standard practice for all commodity products around the world for 100 years,” he told lawmakers, warning that deviating from it risks “imbalance of the supply chain for the whole world,” during the Senate’s PROTECT Committee hearing on March 26.
That framing is not new—but the stakes are sharper in a country where fuel costs ripple quickly into transport fares and food prices. To understand the debate, it helps to strip the jargon. Replacement cost, at its core, is what it would cost today to replace what you are selling.
In the oil industry, that translates into pricing fuel based not on what companies paid for existing stock, but on what it will cost to buy the next shipment—typically benchmarked to global indicators such as the Mean of Platts Singapore (MOPS). It is a forward-looking logic applied to a present transaction.
The economic rationale is straightforward. Oil is a globally traded commodity with volatile prices. If retailers price fuel based on outdated, lower acquisition costs during a price upswing, they risk selling below replacement value. That can erode working capital and, in extreme cases, disrupt supply. Tangmanuswong’s argument hinges on this: pricing must anticipate the next purchase, not reflect the last one, or the system breaks under its own incentives.
But what is coherent in theory becomes contentious in practice. Critics point to the so-called “rockets and feathers” effect: prices shoot up quickly when global oil rises, yet drift down slowly when it falls. Replacement cost pricing, they argue, allows companies to pass on increases immediately—while delays in reductions create a buffer that looks, to consumers, like opportunistic profit-taking on cheaper inventory.
This is where Senator Sherwin Gatchalian’s opposition sharpens the policy debate. Gatchalian has questioned the fairness of applying replacement cost rigidly in a deregulated market, particularly when it appears to amplify price asymmetry. His position, as expressed in hearings and interviews, is that consumers end up paying for future costs that have not yet been incurred, while companies benefit from margins on existing lower-cost stocks. He has pushed for greater transparency in pricing mechanisms and raised the possibility of policy interventions to temper perceived excesses.
The tension, then, is not simply technical—it is philosophical. Replacement cost pricing prioritizes supply continuity and market alignment. It assumes that the discipline of global pricing is the best guarantor of long-term stability. Its critics prioritize fairness and timing, arguing that markets do not always self-correct quickly enough to protect consumers in real time.
Both sides are right, but only partially. The oil industry operates on thin logistical margins where inventory cycles matter; mispricing can indeed trigger shortages. Yet the public’s frustration is equally grounded: when price increases are immediate and decreases lag, trust erodes. In a deregulated environment, perception can be as destabilizing as policy missteps.
The more productive path lies not in abandoning replacement cost, but in refining its application. Transparency is the first lever—clear, verifiable disclosures on how pump prices track global benchmarks can narrow the credibility gap. Second is competition: ensuring enough market players can help compress margins when prices fall. Third is targeted intervention—not blunt price controls, but calibrated tools such as strategic reserves or temporary subsidies during extreme volatility.
The Senate hearing ultimately underscored a deeper truth: pricing models are not just economic instruments; they are social contracts. Replacement cost may be a century-old global practice, as Chevron argues, but its legitimacy in any market depends on whether it balances efficiency with equity. In the Philippines, that balance remains a work in progress.
