Oil Surge Sparks Australian Stock Downturn

Oil prices have surged back above $100 per barrel, causing a downturn in Australian stocks as investors worry about inflation and potential Reserve Bank of Australia rate hikes.

The S&P/ASX 200 fell by 0.5% to 8,661.20, marking an extension of weekly declines. This decline is largely attributed to the impact of higher oil prices on everyday costs via fuel, transport, and electricity, which in turn makes inflation harder to control.

Market expectations are still centered around a cash-rate increase to 4.60%, a near 15-year high. Reuters noted that other potential price pressures include heavy investment in data centers, despite a mixed labor report showing unemployment rose to a five-year high while employment rebounded.

Higher expected rates tend to hurt 'long-duration' stocks first, companies where investors are paying mainly for profits expected further in the future, because a higher discount rate reduces the present value of those future cash flows. This explains why tech stocks fell by 1.5%, with WiseTech Global down about 2% and Xero off 2.9%.
