• AUD/USD sees Monday declines as market risk appetite sours.
• RBA rate call in the pipe for Tuesday.
• Market sentiment set to be titled to the downside for NFP week.

The AUD/USD is washing back into familiar lows for Monday, trading into 0.6340 as broad-market sentiment turns risk-off.

The Aussie (AUD) is down 1.2% from Monday's early high of 0.6445 and off of the day's opening bids by around 65 pips. Market flows are broadly favoring the US Dollar (USD) as investors get spooked by fears of a global economic slowdown.

US ISM Purchasing Manager Index (PMI) figures came in mixed on Monday, limiting Greenback support to safe haven market flows. The US Manufacturing PMI ticked from the previous 47.6 to 49, but prices paid by manufacturers declined, printing at 43.8 versus the expected uptick to 48.6.

Tuesday brings the latest rate call from the Reserve Bank of Australia (RBA), which will be tabled by the RBA's new head, Governor Michele Bullock will be making her debut appearance as the head of the RBA, and investors are broadly anticipating the RBA holding rates steady at 4.1%.

Markets are still anticipating one more rate hike from the RBA, likely due in November, and investors will be keeping a close eye on the RBA rate statement for any clues about the Australian central bank's path forward
