RBA Faces Inflation Expectation Surge: Market Hike Priced In vs. Sticky 5.2% Reality

The market's bet is clear: a 25-basis-point rate hike is priced in for the Reserve Bank of Australia's meeting next week. But the surge in consumer inflation expectations is creating a stark tension between that consensus view and the reality on the ground. The latest data shows a powerful force building that could force the RBA's hand more aggressively than the market is currently expecting.

Consumer inflation expectations have jumped sharply, rising to 5.2% in March. That's the highest level since July 2023 and marks a significant acceleration from the 0.8 percentage point weekly surge that represents the largest single-week increase since the survey began tracking this metric weekly in 2014. This isn't just a minor uptick; it's a forceful repositioning of what Australians believe prices will do, and it's happening amid a spike in geopolitical uncertainty.

The RBA's own February forecast, which guided much of the market's thinking, was for inflation to settle around 4.2%. Deputy Governor Andrew Hauser has now explicitly warned that the central bank's internal view has shifted higher, citing the escalating conflict in the Middle East and associated oil price rises as a clear upside risk to that projection. His message is a direct challenge to the status quo: if inflation expectations disanchor and persist above target, the RBA's credibility and its ability to control inflation could be undermined.

The bottom line is an expectation gap. The market is betting on a single, measured hike in March, with a follow-up in May. Yet the data shows inflation expectations are surging toward 5%, a level that sits well above the RBA's own forecast and its target band. This sets up a classic "sell the news" dynamic if the RBA does act as expected. But if the central bank sees this surge as a signal that inflation is getting out of control, it may need to hike more than once in a row to reset expectations. The market has priced in a 25-bp move; the reality on the ground suggests the RBA may need to act with more force to keep inflation expectations anchored.

The Policy Reality Check: Guidance vs. Data

The disconnect between forward guidance and the latest data is now a central risk. Governor Michele Bullock's recent comments acknowledged that Q3 inflation was slightly stronger than anticipated, with signs of persistence. Yet the market's path was set by the RBA's own February move: a 25-basis-point hike to 3.85% that was in line with expectations. That decision, taken after a period of steady rates, was meant to signal control. But the surge in inflation expectations since then suggests the central bank may have underestimated the durability of price pressures.

ANZ Research's outlook still points to a similar move in May, expecting another 25-bp hike to 4.1%. That forecast is a classic "buy the rumor" play on a predictable policy path. The risk is a guidance reset. If inflation expectations continue to climb toward 5%, as they did in March, the RBA's internal view could shift faster than the market is pricing. The central bank has explicitly stated it will keep a close eye on inflation expectations when setting rates. A sustained breach of the 5% level would challenge the narrative of a gradual, data-dependent pause.

The bottom line is a setup for volatility. The market consensus is for a measured, two-step hike. But the data shows expectations are surging, potentially faster than the RBA's own internal models. If the central bank sees this as a sign that inflation is getting out of control, it may need to act more aggressively than the current guidance suggests. The guidance is for a May hike; the reality on the ground is a widening expectation gap that could force an earlier or larger move to anchor the market's view.

Catalysts and Risks: The March 17 Decision and Beyond

The immediate catalyst is the RBA's next decision, scheduled for March 17. The market consensus is for a repeat of the February move: a 25-basis-point hike to 3.85%. Bank of America has already predicted this, citing the oil shock as a clear reason for the move. The setup is classic: the market has priced in a single, predictable step. The real test is whether the RBA's internal view, which Deputy Governor Hauser says has shifted higher, will force a more aggressive stance.

The key risk is that inflation expectations prove sticky. Even if headline inflation cools from its current levels, the surge in consumer expectations to 5.2% in March could persist. This is the core vulnerability. As Hauser warned, allowing inflation expectations to disanchor is a "clear problem" that could undermine the RBA's credibility. If expectations remain anchored near 5%, the central bank may need to maintain higher rates longer than the current guidance suggests, simply to reset the market's view.

Watch for any shift in forward guidance on the timing of the next hike. ANZ Research still expects a similar move in May, but the data is challenging that path. The RBA has explicitly stated it will keep a close eye on inflation expectations. Any signal from the March meeting that the Board sees these expectations as a more persistent threat-perhaps by hinting at a faster pace of hikes or a longer pause at higher levels-would signal a reset from the current consensus. That would be the clearest sign that the market's priced-in path is no longer the RBA's likely trajectory.
