Energy shocks ripple through the economy almost immediately
In March, Australia found itself caught between two truths at once: headline inflation surged to 4.6 per cent, driven by an energy crisis born of Middle Eastern conflict, while the quieter, more considered measure of underlying prices held steady at 3.3 per cent. It is a familiar tension in economic life — the loud signal and the patient signal, each telling a different story about where things are truly heading. The Reserve Bank, tasked with guiding inflation back toward a 2.5 per cent target, must now decide which story to believe, and how long it can afford to wait before acting.
- Global energy markets, rattled by Middle East conflict, delivered Australia its sharpest inflation jump in recent memory — from 3.7 per cent in February to 4.6 per cent in March.
- The surge has reopened a difficult question for policymakers: is this a temporary shock to be weathered, or the beginning of something that embeds itself more deeply into wages, rents, and everyday costs?
- The Reserve Bank's preferred trimmed mean measure held firm at 3.3 per cent, offering a counterweight to the headline alarm and suggesting core price pressures have not yet broken loose.
- Still, both figures sit above the bank's 2.5 per cent medium-term target, leaving monetary policy in an uncomfortable position — too tight risks choking growth, too loose risks letting inflation run.
- The next move hinges on whether energy prices stabilise or continue to feed through the broader economy, a question no central bank can answer from its meeting room alone.
Australia's inflation picture fractured in March. Consumer prices rose at an annual rate of 4.6 per cent, a sharp climb from 3.7 per cent in February, as conflict in the Middle East triggered an energy shock economists had been anticipating — one drawing comparisons to the oil-driven crises of the 1970s and 80s.
Yet beneath that headline number, a different picture held. The trimmed mean — the Reserve Bank's preferred measure, designed to filter out volatile price swings — remained steady at 3.3 per cent. The gap between the two figures reflects the outsized role energy plays in headline inflation: when oil and gas prices spike, they move through the economy quickly and visibly, without necessarily signalling that wages are rising, rents are climbing, or that businesses are broadly repricing their goods and services.
The Reserve Bank targets 2.5 per cent inflation over the medium term — a goal that now sits well below both measures. The steadiness of the trimmed mean offers some reassurance that the energy shock has not yet fed into deeper price expectations. But the divergence is precisely the kind of signal central banks watch with care. If Middle East tensions ease and energy markets stabilise, headline inflation may retreat on its own. If they don't — or if the shock begins to reshape wage and price behaviour more broadly — the bank may find itself with little choice but to act.
Australia's inflation picture fractured in March, with headline prices jumping sharply while the deeper measure of cost pressures stayed put. Consumer prices climbed at an annual rate of 4.6 per cent last month, a significant leap from 3.7 per cent in February. The acceleration caught few by surprise—economists had been bracing for exactly this kind of shock, knowing that conflict in the Middle East had triggered the worst global energy crisis since the oil-driven recessions of the 1970s and 80s.
But the story splits here. While headline inflation surged, the Reserve Bank's preferred gauge of underlying inflation—a measure called trimmed mean inflation that smooths out volatile price swings—held steady at 3.3 per cent. This divergence matters because it tells two different stories about what's happening in the Australian economy. One narrative says prices are accelerating dangerously. The other says the core pressure on costs remains contained, at least for now.
The Reserve Bank targets inflation averaging 2.5 per cent over the medium term. That goal sits well below where headline inflation now sits, and even the steadier underlying measure is running above the bank's comfort zone. The gap between the two figures—headline at 4.6 per cent, trimmed mean at 3.3 per cent—reflects the outsized impact of energy prices on the overall inflation number. When oil and gas prices spike, they ripple through the entire economy almost immediately, pushing up the headline figure. But they don't necessarily signal that wages are rising faster, that rents are climbing, or that businesses are broadly raising prices across the board.
This distinction shapes what happens next. If the energy shock proves temporary—if Middle East tensions ease and global oil supplies stabilize—then headline inflation could fall back toward the underlying rate without the Reserve Bank needing to tighten monetary policy further. But if energy prices remain elevated, or if the shock begins to feed into broader wage and price expectations, the bank may face pressure to act. The trimmed mean figure suggests that hasn't happened yet, but the divergence between the two measures is precisely the kind of signal central banks watch closely.

Economists had been expecting inflation to jump higher because the war in the Middle East had caused the largest global energy shock since the oil crises of the 1970s and 80s— Economic analysis
La Conversación del Hearth Otra perspectiva de la historia
Why does the Reserve Bank care about trimmed mean inflation when headline inflation is what people actually feel at the supermarket?
Because headline inflation is noisy. Energy prices can spike for reasons that have nothing to do with the health of the economy—a war, a weather event, a supply disruption. Trimmed mean strips out those extremes and shows you what's happening underneath. It's the difference between a single bad day and a trend.
So the March jump to 4.6 per cent—that's mostly energy?
Almost entirely. The Middle East conflict created the biggest energy shock since the 1970s. That flows straight into petrol prices, electricity bills, heating costs. It's real pain for households, but it's not necessarily a sign that inflation is becoming embedded in the economy.
And if it stays high?
Then you have a problem. If energy prices don't fall, or if people start expecting inflation to stay high and demand higher wages to match, then you get a feedback loop. That's when the Reserve Bank gets serious about raising rates.
The RBA wants 2.5 per cent. We're at 4.6 headline and 3.3 underlying. How far off are we?
Headline is nearly double the target. Underlying is a third higher. Neither is where the bank wants to be, but underlying is the one that matters for policy. If that stays at 3.3 or starts falling, the bank can probably hold steady. If it rises, they'll have to move.
What's the most likely scenario?
Energy prices eventually come down. They always do. The question is how long it takes and whether the shock does any lasting damage to inflation expectations in the meantime.
