RBA hikes rates to 15-year high as global bond rout forces Australia’s hand

Key points

• RBA Governor Michele Bullock announced a 25 basis point hike to 4.6%, the highest since 2011.
• This is the first hike in the cycle to directly increase monthly repayments, as most borrowers did not lower payments during the 2025 cuts.
• Global bond yields have surged, with US 10-year yields hitting 5.2% and Australian 10-year yields reaching 5.4%, forcing the RBA’s hand.
• Macquarie Bank was the first to pass on the hike, effective October 15, 2026.
• Markets are pricing in a 60% chance of a sixth hike by mid-2027, with some analysts warning of 'devastating' impacts on the property market.

Background

This follows a period of rate cuts in 2025 that were reversed by three hikes in 2026. In late September, Australia’s unemployment rate rose to 4.6%, its highest since the pandemic, yet inflation remained stubbornly high. The global financial environment has deteriorated significantly, with US national debt exceeding $40 trillion and investors losing faith in the US dollar as a reserve currency, leading to a 'bond market revolt' that has pushed yields to multi-decade highs.

How outlets are covering it

Outlets differ on the primary drivers and consequences. ABC News emphasizes the global context, arguing that the RBA has 'no choice' due to a US-led bond market rout and rising global yields, noting that US 10-year yields have jumped from 4.65% to 5.2% in a month. Yahoo Finance focuses on the domestic impact, highlighting that this hike is unique because it will increase monthly repayments for nearly all borrowers, as most did not reduce payments during the 2025 cuts. The Guardian warns that further hikes could be 'devastating' for the property market, potentially triggering a 15-20% price drop, while noting that affordability has hit a historic low. News.com.au presents a more political view, with Mark Bouris and David Koch blaming government spending and fiscal deficits for inflation, rather than the Middle East conflict cited by the RBA and Treasurer Jim Chalmers. Conversely, property investor Nathan Birch defends the government, attributing the issue to 'global hyperinflation' and international debt problems.

Why it matters

The hike signals a shift from a policy of easing to one of aggressive tightening, with the RBA warning that further hikes may be needed if inflation expectations become embedded. For households, the impact is immediate and severe, as mortgage debt has surged 138% since 2011, meaning the same rate level now carries a much heavier burden. The decision also reflects a broader global trend where central banks are losing control to bond markets, as investors demand higher yields to compensate for perceived risks in major economies, particularly the US.

What to watch

Banks are expected to pass on the 25 basis point hike within 10-14 days, with Macquarie already announcing changes for October 15. The RBA’s next meeting is scheduled for November, where a fifth hike to 4.85% is possible. Markets are pricing in a 60% chance of a sixth hike by mid-2027. Economists like Cameron Kusher suggest that the broad economic impact may force the RBA to cut rates sooner than the current market consensus of 18 months. The government faces pressure to curb spending, with critics arguing that fiscal deficits are undermining the RBA’s efforts to control inflation.
