The AUD/USD pair has refreshed its day’s low at 0.7083 as investors have turned risk-averse amid the interest rate decision by the Federal Reserve (Fed) this week.A softer risk tone - as depicted by a weaker trading sentiment around the equity markets - is seen as a key factor driving flows away from the risk-sensitive Aussie. Despite China's move to scale back its strict zero-COVID policy in December, the worst yet COVID-19 outbreak in the country has been fueling uncertainty about a strong economic recovery. This, in turn, tempers investors' appetite for riskier assets and keeps a lid on any optimism in the markets.
