AUD/USD down to threaten 0.6677 as European shares fall further nL4N3361SL

0.6677 was Thursday's low, after biggest one-day fall since March 2020

Thursday's tumble was fuelled by risk aversion (AUD is risk-sensitive)

Recovery rally from 0.6677 topped out just shy of 0.6737 (21DMA) in Asia

0.6669 (last week's low) is a support point sub-0.6677 (0.6670 is 100DMA)

There is a large 0.6700 option expiry for the 10am ET NY cut nL1N3360CI
