RBA cash rate update: what it means
The RBA has made a material upward revision to its inflation forecasts in its May Statement. The central bank now expects headline CPI, the broadest measure of inflation, to peak at 4.8%/yr in Q2 26, before gradually declining. The trimmed-mean, which strips out the most volatile price movements and is the RBA's preferred measure of inflation, is forecast at 3.8% per year over the same period.
The gap between headline and trimmed mean inflation largely reflects higher fuel prices driven by the war in Iran. Headline inflation is the figure that feeds into wage negotiations, rent reviews and government benefit adjustments each year — and it is the measure that most directly shapes how households feel about the cost of living. The RBA monitors both, but the consequences of elevated headline inflation extend well beyond what the trimmed mean alone captures.
Energy prices are one of the main channels through which geopolitical events affect the broader economy. The Strait of Hormuz is one of the world’s most important energy corridors, with a significant share of global oil and liquefied natural gas exports passing through this route each day.
Higher energy prices can flow through to transportation, manufacturing and consumer prices, influencing inflation expectations and interest‑rate outlooks. For markets, the key question is not simply how high oil prices move in the short term, but how long elevated prices persist.
Higher inflation combined with rising interest rates creates double pressure on household budgets. Real household disposable income, that is, what families can actually buy with their after-tax income once inflation is accounted for, is being squeezed from both sides.
The RBA has made a significant downward revision to its forecast for real household disposable income, now expecting growth of just 1.1% per year by the end of 2026, down from a prior forecast of 1.8%.
The impact of rate rises on Australian households is more direct than in many other countries, because most home borrowers here are on variable rate mortgages. When the RBA moves, mortgage repayments move quickly. The upshot is that the three rate rises since February will start to bite, and with consumer sentiment at historically low levels, the confidence effect can amplify the real impact further. The net result is weaker household spending, particularly in discretionary categories, which will weigh on earnings growth and company profits through 2026.
Australia stands somewhat apart from other major economies right now. In the United States, Eurozone, United Kingdom and Canada, central banks have not reversed their rate cuts, and last week all four left rates unchanged. Japan has continued its own shallow tightening cycle, but has moved only in one direction. Since the war in Iran began, market expectations for the major global central banks have shifted in a more hawkish direction — pricing in fewer cuts and potentially more hikes — but none have yet acted on it.
This divergence has a direct consequence for the Australian dollar. As Australian interest rates rise relative to those abroad, the yield advantage of holding Australian dollar assets increases, attracting capital inflows and pushing the currency higher. The AUD has appreciated approximately 7% against the US dollar since the start of the year.
Today's rate rise was expected, and markets had already adjusted prices in anticipation. The immediate reaction is therefore likely to be contained. Financial markets have priced a peak in the RBA cash rate of 4.7% (i.e. another 35bp of policy tightening). That pricing reflects the balance of risks around the outlook for inflation and the RBA’s concerns around longer-term inflation expectations adjusting higher. The more important question is what the economic environment taking shape over 2026 means for investment portfolios.
For Australian shares, the combination of slowing growth, higher borrowing costs, and weaker consumer spending creates a more challenging backdrop for company earnings. Businesses with significant exposure to domestic discretionary spending, such as retailers, consumer services and media, face the most direct headwind. The financial sector, the largest on the ASX, is more nuanced. Higher rates can support bank profitability in the short term by widening the margin between what banks earn on loans and pay on deposits, but a slowing economy, softer credit growth and the prospect of rising loan defaults present a meaningful offset. Sectors less sensitive to the domestic economic cycle, such as resources and healthcare, may prove more resilient. Investors should expect earnings growth in Australia to moderate through 2026.
On the other side of the ledger, with the cash rate back at 4.35%, the income available from defensive assets, including term deposits, bonds and cash, has improved materially. For more conservative portfolios or for investors looking to increase their defensive allocation, the returns available without taking significant risk are meaningfully better than they were two years ago.
More broadly, monetary policy works with a lag. The full economic impact of the three rate rises in 2026 has not yet fully flowed through to households and businesses. This is not a reason to panic, but it is a reason to remain disciplined and focused on long-term fundamentals rather than short-term noise. History shows that well-diversified portfolios are built precisely for environments like this one. Periods of economic adjustment are uncomfortable, but they are a normal part of the investment cycle, and they pass.
