Apr’26 CPI: Cooling at the surface, sticky at the core

April’s inflation result gives the Reserve Bank of Australia (RBA) less reason to panic than the March print, but not enough reason to relax. The unwind in fuel has pulled headline CPI lower, yet the lift in trimmed mean inflation confirms that domestic price pressures remain sticky beneath the surface. For policymakers, the most visible source of inflation is fading, but the more policy-relevant underlying measures are proving slower to return to target. That keeps the RBA firmly in wait-and-watch mode.

Headline inflation has eased, but mainly for the “right now” reasons

The Consumer Price Index rose 4.2% over the year to April 2026, down from 4.6% in March. The step-down is meaningful, but it is also heavily influenced by the reversal of part of the March fuel surge rather than a decisive broad-based easing in inflation momentum. The largest contributors to annual inflation remained Housing (+6.3%), Transport (+6.6%) and Food and non-alcoholic beverages (+2.8%).

That said, policymakers were never likely to react mechanically to the March spike or the April payback. The RBA had already made clear in its May decision and Statement on Monetary Policy that while higher fuel prices were directly adding to inflation, the larger concern was whether those shocks would spill over into the pricing of other goods and services. That means April’s moderation in the headline will be welcomed, but only cautiously.

The real policy signal lies in core inflation and it moved the wrong way

The more important detail in this release is that trimmed mean inflation rose to 3.4% yoy in April from 3.3% in March. That is only a modest increase, but it is significant in context: headline inflation may have eased, yet the RBA’s preferred measure of underlying inflation has not. Instead, it has edged further away from the target band and reinforced the message that inflation persistence remains the central policy challenge. 

This is what makes the April print more hawkish than the headline alone suggests. In March, the case was that the fuel-driven spike made the optics worse while trimmed mean at 3.3% suggested underlying inflation was elevated but not accelerating sharply. April changes that assessment at the margin. The headline shock is fading, but core inflation has drifted higher, implying the inflation pulse is becoming less about one-off global energy effects and more about embedded domestic pricing pressures. 

The RBA’s May forecasts reinforce why this matters. The Bank expects trimmed mean inflation to remain above 3% until mid-2027 in its baseline and only return to around the midpoint of target by mid-2028. A monthly print showing core inflation rising rather than easing is therefore unlikely to challenge the Board’s existing view that inflation will stay above target for some time.

Labour market: early signs of softening?

At the same time, the labour market is showing initial signs of cooling. The unemployment rate rose to 4.5% in April (from 4.3%), with employment falling by around 19,000. Despite this, hours worked still rose, indicating firms are adjusting labour utilisation at the margin rather than aggressively shedding workers. 

This shift matters for policy. The RBA has been expecting a gradual easing in labour market conditions as higher interest rates work through the economy, and recent forecasts already point to below-trend growth and a modest rise in unemployment over the period ahead.

Policy implications: from inflation shock to policy balancing act

Taken together, the April data reinforces a shift in the policy narrative. The March CPI print was dominated by an inflation shock; April instead highlights a more difficult balancing act. While the fuel-driven surge in inflation may be beginning to unwind, underlying inflation has not yet turned decisively lower and at the same time, the labour market is no longer tightening and may be starting to soften.

For the RBA, this argues for patience rather than further tightening. The bar for another rate hike remains high as activity slows, but the stickiness in core inflation means the bar for easing is even higher. Until there is clearer evidence that underlying inflation is on a sustained path back toward target, and that the labour market is not deteriorating more sharply, the most likely outcome is an extended hold, with policy bias gradually shifting from tightening risk to growth risk.
