Australian shares fall and the market resumes its downtrend as investors react to renewed concerns about energy prices and global interest rates. Multiple outlets report that energy stocks rise in the short term as oil-market expectations shift.

The move follows US threats to impose historic sanctions on Iran, prompting investors to price in the possibility of a prolonged disruption to oil supply. This expectation supports energy-related stocks even as broader sentiment remains cautious.

Other cited pressures include uncertainty around bond markets, which can affect borrowing costs and valuations for risk assets. Taken together, the reports frame the session as a tug-of-war between sector-specific gains tied to oil and wider risk-off behaviour driven by fears of sustained supply disruption and sensitivity to movements in interest rates.
