$40 Fuel Cap: Chalmers Says Treasury Models ‘Pretty Conservative Now’ as National Cabinet Prepares to Meet

$40 fuel cap appears in public discussion as Treasurer Jim Chalmers says Treasury’s fuel price modelling looks ‘pretty conservative now’ and national cabinet will meet again next week (ET) to address the country’s fuel crisis. Chalmers has asked Treasury to run additional, more challenging scenarios after earlier modelling that included global oil at 100 bucks a barrel for shorter and longer periods.

What Happens When Treasury’s Models Look ‘Pretty Conservative’?

Treasurer Jim Chalmers said he asked Treasury to model a range of scenarios and has now asked for tougher circumstances to be examined. He described earlier scenarios — one with global oil at 100 bucks a barrel for a shorter period and another for a longer period — as looking “pretty conservative now, ” and said the government is “constantly monitoring and analysing the consequences and potential consequences for Australia. “

Senior government attention is being signalled by the decision to reconvene national cabinet next week (ET). Officials are working around the clock, the treasurer said, and questions have been raised about the country’s ability to secure fuel imports from Asia after mid-April. Those concerns have pushed modelling beyond the initial two scenarios toward more severe outcomes, and they directly shape discussions about price interventions and supply measures.

What If a $40 Fuel Cap Is Proposed?

A policy proposal framed as a $40 Fuel Cap would enter this uncertainty set shaped by Treasury’s updated scenarios and cabinet deliberations. The debate is taking place against a backdrop of operational strains inside public services, where staff have highlighted the consequences of constrained resources for core functions.

• Best case — Treasury’s expanded modelling shows international supply lines hold, the 100-bucks-a-barrel scenarios are short-lived, and domestic measures stabilise retail availability without emergency price controls.
• Most likely — Price pressure persists; modelling that once looked conservative proves optimistic; national cabinet weighs temporary, targeted interventions, including supply coordination and fiscal cushions, while supply chains face intermittent strain.
• Most challenging — Imports are disrupted after mid-April, global oil remains elevated for longer periods, and policymakers confront simultaneous supply shortfalls and acute price spikes, increasing pressure to consider caps or rationing measures.

Each path is explicitly linked to the Treasury work Chalmers described: models built around a 100 bucks a barrel scenario and the additional, more challenging runs he requested. The national cabinet meeting next week (ET) will be the immediate venue where those projected outcomes are weighed against operational realities.

The wider public-service context matters: staff working in essential broadcasting and emergency services have warned that constrained budgets and staffing pressures reduce capacity in critical areas. Those operational limits factor into how any intervention — including a price cap — could be designed and implemented.

Decision-makers face trade-offs between short-term relief and longer-term market signals. The treasurer has signalled urgency by expanding modelling and keeping national cabinet engaged; at the same time he emphasised ongoing monitoring of the consequences for Australia.

Readers should expect a tightened policy window over the coming days as cabinet meets and Treasury delivers its tougher scenarios. If policymakers opt for direct price controls, the form, scope and duration of a $40 fuel cap will be shaped by the same modelling that Chalmers now calls “pretty conservative now” — and by the practical limits identified across public services and supply chains. The key immediate pivot point is national cabinet next week (ET); beyond that, stakeholders should prepare for sustained, uncertain deliberations over a $40 fuel cap
