US strikes on Iran drive oil higher, Treasury yields to daily peaks
Escalating conflict in the Middle East has pushed energy costs up and sent bond yields to their highest levels of the day, reviving inflation concerns among investors.
The United States has launched further strikes on Iran, causing the existing conflict to flare up and triggering immediate volatility in global markets. The escalation has pushed oil prices higher while sending US Treasury yields to their highest levels of the day.
Investors are increasingly concerned that the geopolitical tension could trigger a new bout of inflation. The rise in energy costs has added to the pressure on central banks and markets already grappling with persistent price pressures.
This development follows recent reports that US President Donald Trump declared an intention to make the Strait of Hormuz US territory, a claim reportedly rebuffed by Iran. The diplomatic friction has heightened uncertainty regarding the stability of key shipping lanes for global energy trade.
For Australian policymakers, the move comes at a sensitive time. The Reserve Bank of Australia is on track for a fourth interest rate hike to combat persistent inflation, even as house prices fall in more than 90 per cent of Australian suburbs.
RBA Governor Michele Bullock has indicated that the housing market downturn is “not the main game” for monetary policy, prioritising inflation control. However, the latest surge in oil prices provides fresh impetus for the bank to maintain its tightening stance.
The conflict also unfolds against a backdrop of broader trade disputes, including a 50 per cent tariff increase on Canadian cars, trucks, and auto parts that is scheduled to take effect from 1 January 2027.
