US and Iran have agreed to reopen the Strait of Hormuz, an important oil shipping route, easing a key source of global energy uncertainty. The development has been welcomed by central banks, including the Reserve Bank of Australia (RBA), as lower oil prices reduce the risk of inflationary pressures stemming from energy costs.
Following the announcement, S&P 500 futures rose by more than 1 percent, signaling improved market sentiment. However, broader economic indicators remain subdued, with consumer and business confidence in Australia sharply declining, household spending contracting, unemployment rising, and residential property prices falling more rapidly since the national budget was released.
RBA Governor Michele Bullock noted that earlier interest rate hikes this year had provided the bank with room to monitor how global events and economic shocks would impact Australian households and businesses. The reopening of the Strait of Hormuz now widens that margin, offering some relief by reducing the threat of sustained oil price spikes. Nonetheless, inflation remains significantly above the RBA's target, while economic pressures build.
In recent weeks, National Australia Bank (NAB) has underscored the challenges facing the Australian economy. CEO Andrew Irvine issued an open letter acknowledging growing uncertainty among citizens. Meanwhile, NAB’s chief economist Sally Auld revised her outlook, moving away from anticipating further rate hikes toward expecting an extended pause, with rate cuts only likely in the second half of 2027. Auld cited changes in taxation policy as an external tightening of financial conditions, contributing to slower growth in housing prices and credit, and noted that core inflation is expected to stay above target into mid-2027.
Similarly, ANZ Bank has lowered its housing market forecasts. It now projects capital city home prices to decline by 2.1 percent this year and 3.3 percent in 2027, a steep revision from earlier expectations of growth. ANZ economists attribute the sharper-than-expected housing slowdown to global uncertainty, cumulative interest rate hikes totaling 75 basis points, and recent budget-driven housing policy changes. Sydney and Melbourne have experienced the greatest declines, with price drops forecast to extend nationwide next year.
Other economic analysts have weighed in on the RBA’s policy trajectory in this environment. HSBC chief economist Paul Bloxham advocates for a cautious pause in interest rate adjustments, highlighting weakening growth signals and falling house prices while remaining vigilant against unintended inflationary spirals. Goldman Sachs’ Andrew Boak expects the RBA to maintain current rates following earlier increases that created policy flexibility but warns that further tightening could be required if wage and services inflation intensify. RBC’s Mary Jo Vergara similarly anticipates an on-hold stance, citing restrictive policies and softer data that allow the central bank to sustain firm inflation messaging without immediate action.
The reopening of the Strait of Hormuz and the associated decline in oil prices help reduce some near-term inflation risks for the RBA by mitigating its earlier adverse scenario predictions, which involved Brent crude soaring to as high as US$145 per barrel. Yet, with the Australian economy showing signs of slowing and fiscal measures tightening financial conditions, the central bank’s challenge remains ongoing. While improved energy conditions and subdued activity may ease immediate pressures, controlling inflation continues to be a central focus for policymakers.
