Taxing Gas In A Time Of Crisis
There is a temptation in moments like this to think we are witnessing something new. We are not. Energy shocks, geopolitical conflict and policy overreactions have a long history. What is different this time is that the end game is already in motion. As we have discussed may times, the transition is not theoretical anymore, it is occurring.
The latest conflict in the Middle East has once again sent energy markets into an upward spin. Oil prices surged to around US$120 per barrel, roughly 50 per cent higher than pre conflict levels. That feeds directly into petrol prices, logistics costs and inflation.
This is now the second major energy shock in five years. The first should have been enough to change behaviour. It was not.
A war we did not need, but a consequence we may benefit from
There is a broader point here. This is a war we did not need. It is a disruption layered on top of an already fragile system. But while the cause is frustrating, the consequence is clear. It accelerates the inevitable.
High oil and gas prices do not just hurt consumers. They compress the payback period on alternatives.
Renewables, storage and electrification were already competitive in many cases. What the latest price spike does is shift the economics decisively. Projects that previously looked marginal now look compelling. Decisions that could be delayed now become urgent.
In our view, the payback period has shortened.
That matters. Because capital follows returns, not narratives.
Early adopters are now being rewarded
This is where the investment story becomes interesting.
For years, early adopters of renewable technologies were often criticised. The economics of such a move were not always obvious. The upfront costs were high. The benefits versus costs were, at times, marginal.
That is no longer the case.
Households and businesses that invested early in solar, batteries or electrification are now seeing the benefits. Their exposure to volatile fossil fuel prices is lower. Their energy costs are more predictable. In many cases, they are effectively insulated from the worst of the price shocks.
The market is now rewarding behaviour that once looked premature.
This is how transitions happen. Slowly at first, then all at once.
The policy reflex returns
Against this backdrop, governments are once again looking for short term fixes.
Australia sits in a unique position. We are exposed to higher global oil prices as an importer, while simultaneously benefiting from higher gas prices as a major LNG exporter.
That creates a tension. Households are squeezed, while producers generate extraordinary profits.
Enter the windfall tax debate.
As per a report that appeared in the Conversation (1), these profits are largely driven by global price shocks rather than productivity gains. The argument is that a portion of these gains should be captured and redistributed to support households.
The Australian Senate has now moved to examine this more closely, launching an inquiry into gas taxation settings and how revenues could be used to offset rising costs. (2)
On paper, it is a neat solution.
The short term case for intervention
There are obvious advantages to a temporary windfall tax.
As per the report in the Conversation, Australia’s gas industry is largely foreign owned, meaning a significant share of the profits flows offshore. Capturing some of that value domestically could provide immediate relief to households without weakening the federal budget.
This stands in contrast to fuel excise cuts. As per the same report, the last time this was tried it cost A$5.6Bn in lost revenue and delivered only temporary relief.
A targeted levy, if designed properly, could be more efficient. It could fund direct support measures. It could ease inflationary pressure. It could even be redirected into transition infrastructure.
In a crisis, that is appealing.
The long term risk we cannot ignore
But short term fixes often come with long term consequences.
Energy companies have been quick to warn that a poorly designed windfall tax risks undermining investment. As highlighted in the AFR, major producers argue that sudden policy changes could deter capital and push investment to more stable jurisdictions. (3)
That risk is real.
Large scale energy projects require significant upfront capital and long time horizons. Investors need certainty. If governments are seen to tax the upside without sharing the downside, capital will look elsewhere.
There is also a broader strategic consideration. As global buyers look to diversify away from Middle Eastern supply, Australia has an opportunity to attract investment. Undermining that position through policy instability would be a costly mistake.
An alternative approach, as suggested in the AFR in a separate article, is to monetise future Petroleum Resources Rent Tax revenues through financial markets rather than imposing new taxes. (4)
It is a more nuanced solution. Less politically appealing, but arguably more effective.
Short term versus long term
This is where the distinction becomes critical.
In the short term, governments need to manage cost of living pressures. That may require intervention. It may involve targeted support, temporary levies or market monitoring.
But in the long term, the objective is clear. Fossil fuels need to be phased out.
These are not contradictory goals. They are sequential.
Short term policy should not undermine long term direction.
The danger is not acting. It is acting poorly.
The transition is already underway
It is worth stepping back.
The shift away from fossil fuels is not being driven solely by policy. It is being driven by economics.
Every energy shock accelerates the transition. Every spike in oil and gas prices improves the relative economics of alternatives. Every period of volatility reinforces the value of energy independence.
We are weaning ourselves off fossil fuels, not because we want to, but because it increasingly makes financial sense.
That process is uneven. It is messy. But it is happening.
The Bottom Line
This crisis will pass. They always do. But the effects linger.
Higher oil and gas prices are painful in the short term, but they are also accelerating the transition that will ultimately reduce our reliance on them. The payback period on alternatives is shortening. Early adopters are already seeing the benefits.
Windfall taxes may provide temporary relief, but they must be designed carefully. Poor policy risks doing more harm than good.
The real takeaway for investors is simple. Follow the economics. The direction of travel is clear. The timing is being brought forward.
