• AUD/USD attracts some intraday sellers after touching a one-week high on Wednesday.
• Rebounding US bond yields revive USD demand and exert some pressure on the pair. 
• The RBA’s hawkish tilt and a positive risk tone could help limit losses for the Aussie.

The AUD/USD pair retreats from the vicinity of mid-0.6500s, or a one-week high touched earlier this Wednesday and extends its steady intraday descent through the first half of the European session. The downward trajectory drags spot prices to a fresh daily low, around the 0.6515 region in the last hour and is sponsored by the emergence of some US Dollar (USD) dip-buying.

The US Treasury bond yields rebound swiftly after the overnight sharp fall amid the growing conviction that US President-elect Donald Trump's expansionary policies will boost inflation and limit the scope for the Federal Reserve (Fed) to cut rates. Apart from this, the worsening Russia-Ukraine conflict turns out to be another factor underpinning the safe-haven buck, which, in turn, is seen exerting some downward pressure on the AUD/USD pair. 

Meanwhile, the initial market reaction to Russia's announcement that it would lower its threshold for a nuclear strike faded after comments from Russian and US officials eased concerns about the onset of a full-blown nuclear war. This is evident from a generally positive tone around the equity markets, which could act as a headwind for the safe-haven Greenback and help limit the downside for perceived riskier currencies, including the Aussie.
