Will Interest Rates Rise after the Reserve Bank (RBA) meets Tuesday, March 17th.
Yes, a 0.25% RBA rate hike is highly likely. Driven by global energy spikes following the conflict in Iran, the Australian cash rate is tipped to hit 4.10%. For a standard $385,000 mortgage, this could add $64 per month to your monthly mortgage repayments.

The “Stand-Out” RBA: Why Australia is Moving While the World Waits
While eight major central banks meet this week—including the US Federal Reserve and the Bank of England—the Reserve Bank of Australia (RBA) is expected to be the only one to pull the trigger on a rate increase.
While policymakers in the UK, Eurozone, and Canada are “holding fire” for now, economists warn that global stability is shifting. Australia’s unique inflation pressures mean we are leading the charge in this new round of tightening.
The “Iran Factor”: Why Petrol and Mortgages are Linked
The primary driver for this sudden shift is the outbreak of war in Iran over two weeks ago. This conflict has had a direct hit on global energy:
-
Oil Prices: Soared 50%, climbing well above $100 USD per barrel.
-
Supply Chain: The closure of the Strait of Hormuz has choked off 20% of the world’s energy supply.
For Perth residents, this isn’t just a “global news” story. Higher oil prices feed directly into local inflation, forcing the RBA to act aggressively to keep the economy from overheating.
What the Markets are Saying
Before the conflict began, the market saw only a 20% chance of a rate rise this month. Today, bond traders have dialed that up to a 77% certainty.
The Predicted Move:
-
Current Cash Rate: 3.85%
-
Expected New Rate: 4.10%
-
Market Sentiment: Expecting the RBA to “keep a lid” on inflation before it spirals.
What This Means for Your Perth Property
If you are currently on a variable rate or coming off a fixed-term loan, this news confirms that the “pause” in rate hikes is officially over.
-
Borrowing Capacity: Every 0.25% increase slightly reduces how much the bank will lend you. If you are house-hunting in suburbs like Booragoon or Applecross, getting a pre-approval now is vital.
-
Refinancing: With Australia moving faster than the US and Europe, local banks may adjust their products quickly. Comparing the market today could save you thousands over the next year.
