Australia’s TD-MI Inflation Gauge rose to 4.3% year-on-year in March. It had been 3.6% in the previous reading.
The data point shows an increase of 0.7 percentage points from the prior figure. The measure tracks changes in prices over time.
Inflation Shock Raises Rate Expectations
We’ve seen a significant jump in the monthly inflation gauge to 4.3% in March, a sharp acceleration from the previous 3.6%. This unexpected rise puts immense pressure on the Reserve Bank of Australia and all but eliminates the chance of a rate cut this year. Traders should now be pricing in a much higher probability of a rate hike at the RBA’s May or June meeting.
The market had been pricing in a steady cash rate through mid-2026, but this new data makes that view obsolete. We should look at buying futures contracts on 90-day bank bills, as their yields will rise to reflect higher rate expectations. This view is strengthened by recent retail sales data which showed a 0.9% jump in February, suggesting consumer demand remains too strong.
A more hawkish RBA stance typically means a stronger Australian dollar, especially as other central banks consider easing. We are considering buying AUD/USD call options to profit from a potential rise in the currency against the US dollar. We remember how the RBA’s aggressive hiking cycle in 2022 and 2023 caused sharp, albeit temporary, rallies in the Aussie dollar.
This inflation reading is a clear headwind for the Australian stock market, as higher borrowing costs can squeeze corporate profits. We are positioning for potential downside in the ASX 200 by looking at shorting SPI 200 futures contracts or buying protective put options. As we saw in 2025 when rate hike fears resurfaced, interest-rate sensitive sectors like technology and real estate were the first to feel the impact.
