What is changing or failing?

The IEA’s Oil 2025 medium-term outlook forecasts global refined-product demand peaking at 86.3 mb/d in 2027, while net capacity continues to grow through 2030. It expects pressure to fall particularly on higher-cost assets in mature demand centres. This is a forecast, not a site-specific verdict.

The shorter-term picture is less linear. In its June 2026 Oil Market Report, the IEA projected a sharp contraction in 2026 demand and refinery runs followed by a 2027 rebound as disrupted supply and trade flows normalise. The executive implication is not to manage to one forecast. It is to test whether the refinery remains competitive through both a constrained near-term market and a structurally more competitive medium-term market.

A refinery can respond with broad cost reduction and still miss the real constraint. Product yield, energy intensity, maintenance exposure, working capital, commercial flexibility and decision speed interact differently by asset and market position.

02

Why does it matter commercially?

When capacity exceeds the call on refined products, average performance becomes less useful than marginal economics. A small operating loss, slow grade-change decision or poorly governed maintenance trade-off can determine whether a barrel contributes or destroys value.

The WIIFM for management is sharper capital allocation: protect the few capabilities that sustain margin and stop funding complexity that cannot clear a defined economic threshold.

03

What must management decide?

Management must decide which operating capabilities are strategically differentiating, which are simply expensive and which decisions need a faster cadence as market conditions move.

The right starting point is one named margin or cost problem with an owner and a measurable baseline—not a refinery-wide optimisation claim.

Test four operating positions

  • Constrained market: which products and customers justify scarce feedstock or capacity?
  • Normalisation: which temporary costs or workarounds must unwind before they become structural?
  • Overcapacity: which unit, product or operating mode loses money first at the margin?
  • Transition: which flexibility creates paid optionality, and which merely adds complexity and fixed cost?

A decision that works in only one of these positions should be labelled as a scenario bet, not a general improvement.

04

What evidence is required?

  • Contribution and constraint by product and operating mode
  • Energy, yield, maintenance and working-capital drivers behind the selected margin
  • Decision latency and exception history in the relevant workflow
  • Capital required to protect or change the position
  • Scenarios showing what must be true for the intervention to pay
  • Cash and contribution response at different utilisation, crack and energy-cost conditions
  • Trigger points for protect, improve, idle, repurpose or exit decisions

05

What should happen next?

  1. Select one margin-critical workflow or cost line.
  2. Quantify value at stake across two or three plausible market conditions.
  3. Separate structural asset constraints from management and workflow constraints.
  4. Make the protect, improve, redesign or stop decision with a 90-day execution path.
