SYDNEY, May 28 (Reuters) - The Australian and New Zealand dollars edged back on Thursday after the failure to breach major chart highs led to profit taking on recent gains, while a drop in the yuan provided an extra reason to sell.
The Aussie faded 0.4% to $0.6592 AUD=D3 , having reached an 11-week top of $0.6680 on Wednesday only to stall short of resistance at $0.6685.
It also failed to sustain a break of the 200-day moving average at $0.6658, and now looks set to test support around $0.6568.
The kiwi dollar eased to $0.6174 NZD=D3 , from a 10-week peak of $0.6232, and now has support at $0.6150.
The Aussie was sold in part as a liquid proxy for the Chinese yuan which has been sliding in recent days as a war of words with Washington heated up.
The offshore yuan hit a record low of 7.1966 per dollar overnight CNH= , stirring speculation Beijing would let the currency depreciate as a trade lever against the United States.
That risk offset upbeat comments from Reserve Bank of Australia (RBA) Governor Philip Lowe who held out hope the economic downturn might be less severe than first feared, given the country's success in containing the coronavirus. he also warned the way ahead would be tough and interest rates would have to remain at all-time lows for years to come, helping keep 10-year bond yields AU10YT=RR down at 0.89%.
Three-year bond futures YTTc1 were steady at 99.740, staying snug to the RBA's yield target of 0.25%.
The economic challenge was underlined by data on business investment which showed a 1.6% drop in the March quarter and a sharp decline in spending plans for 2020/21.
"The downgrade was the first at this early stage of the planning cycle since the 1990s recession, and the largest since at least the mid 1970s," said NAB economist Kaixin Owyong.
"The 2019-20 estimate points to a roughly 16% fall in nominal investment in Q2," she added. "The data underscore the importance of restoring confidence and supporting business investment for the recovery to be sustained." (Editing by Jacqueline Wong)
