Tim Waterer, chief market analyst at KCM Trade said sentiment was subdued as markets awaited key interest rate decisions from the Federal Reserve, Bank of Japan and Bank of England later this week.
“Risk Aversion was doing the rounds on the Australian market today ahead of what is shaping is a big week of central bank decisions around the globe,” Mr Waterer said.
“Investors will be particularly sensitive about what sort of messaging comes from Fed Reserve chairman Powell about the future path of US interest rates.”
Mr Waterer added that with recent US inflation readings coming in above expectations, markets would be wary of further hikes at the Fed’s November meeting.
“If we do see sort of a continuation of these high oil prices feeding into higher inflation and cost pressures in the economy, it's certainly not out of the question that the Fed might have to act again before year end,” he added.
