Interest rates in Australia are projected to reach an 18-year high soon, as per forecasts from Westpac, one of the country’s leading banks. The bank attributes this anticipated increase to ongoing geopolitical tensions in the Middle East and surging oil prices. As a result, Westpac predicts that mortgage holders can expect three additional rate hikes in the coming months, specifically in May, June, and August, following two increases already implemented at the beginning of 2026. This marks a revision upward, with two more cash rate increases than previously expected.
Currently, interest rates have ascended from 3.60% at the end of 2025 to 4.15%. If Westpac’s forecasts hold true, rates could inflame to 4.85% by August, a peak not seen since late 2008. According to Luci Ellis, Westpac’s chief economist, governmental initiatives like halving the fuel excise—announced recently—might not be sufficient to counter this trajectory.
Ellis explained that the prolonged disruption in fuel supply, particularly due to the ongoing conflict in the Strait of Hormuz, contributes to these concerns. She noted that even with measures taken to curb costs, the rapid escalation of oil and fuel prices has a fast ripple effect across other goods and services in the Australian economy.
While the fuel excise reduction may temporarily ease headline inflation, it’s anticipated that inflation will peak around 5.4%. Currently, inflation sits at 3.7%, reflecting data that predates the new economic uncertainties resulting from the Middle East conflict. Additionally, Ellis indicated that the Reserve Bank of Australia (RBA) will likely be compelled to respond with rate increases as inflationary pressures persist.
The ramifications of rising interest rates could extend beyond household finances, with expectations that the cash rate hike may drive unemployment rates upwards, potentially hitting 5%. Ellis warns that economic growth in Australia may also experience a slowdown in the face of these changes.
In summary, as Australia navigates these turbulent waters, both mortgage holders and the broader economy could face significant challenges in the months ahead, making it a critical period for financial stakeholders.
