SYDNEY/WELLINGTON, July 12 (Reuters) - The Australian and New Zealand dollars were thrown on the defensive on Thursday as their triple exposure to Asia, exports and commodities left them hostage to the fallout from a Sino-U.S. trade conflict.
The Aussie dollar AUD=D3 was stuck at $0.7374, having shed 1.2 percent overnight as its U.S. counterpart jumped across the board. The retreat from resistance at $0.7480 ruined what had been a promising rally and turned technicals bearish again.
"That loss comes as traders access the Aussie dollar's deep pool of liquidity to express their worst fears about the impact on the Australian economy but, possibly more so, their worries about global growth as trade tensions escalate to dangerous levels," said Greg McKenna, chief market strategist at CFD and FX provider AxiTrader.
"The break of $0.7393 leaves the Aussie open to a fall to recent lows around $0.7305/10. Should that break then $0.7170/7200 becomes the target zone."
Australia's economic fate is entwined with China, given the Asian giant is its single largest export market and the world's biggest buyer of commodities.
So President Donald Trump's plans for tariffs on $200 billion of Chinese imports are a threat to both. the trade measures implemented to date are too small to knock the global economy off track, the concern is that we are at the start of a cycle where retaliation leads to further retaliation and other countries start raising their tariffs to protect their industries from the fall-out," said Tony Kelly, a senior economist at NAB.
Commodity markets were certainly spooked with oil and base metals diving overnight. Copper hit its lowest in a year and many consider the industrial metal to be a leading indicator of global economic activity.
All of which was negative for New Zealand, another open economy that relies heavily on resource exports to Asia and tourism from China.
The kiwi duly crumbled to $0.6750 NZD=D3 , while its 1.2 percent loss on Wednesday ranked as the sharpest daily decline since February. There was some chart support around $0.6737, ahead of a recent two-year trough of $0.6688.
"AUD and NZD demonstrated they are typically the most sensitive G10 currencies to global trade news," said Westpac strategist Imre Speizer, in a research note.
New Zealand government bonds 0#NZTSY= eased a fraction, sending yields 0.5 basis points higher towards the long end of the curve.
Australian government bond futures dipped but were still near recent three-month highs. The three-year bond contract YTTc1 was off half a tick at 97.935, while the 10-year contract YTCc1 fell 1.5 ticks to 97.3700. (Editing by Jacqueline Wong)
