SYDNEY, Feb 3 (Reuters) - The Australian dollar was precariously poised near a decade trough on Monday, as short-term bond yields hit all-time lows on wagers interest rates would have to be cut at least once to offset the economic fallout from the coronavirus.
The Aussie was hanging on at $0.6689 AUD=D3 having dived as deep as $0.6683. It slid 2% last week to threaten its October trough at $0.6670, and a break there would take it to territory last trod in early 2009.
