SYDNEY/WELLINGTON, April 7 (Reuters) - The Australian and New Zealand dollars tumbled to more than four-month lows on the yen as investors fled risk after the United States fired a barrage of missiles against a Syrian air base controlled by President Bashar al-Assad's forces.
The Australian dollar AUDJPY=R dropped to 82.84 yen, its lowest since mid-November on concerns about a potential escalation in the Syrian conflict following the U.S. attack.
The New Zealand dollar NZDJPY=R slipped to 76.74 yen.
Yields on Australian 10-year bonds AU10YT=RR dropped sharply to their lowest since mid-November at 2.52 percent as high-rated sovereign bonds rallied globally.
The missile strikes, launched in retaliation to a deadly chemical attack in a rebel-held area, raises the risk of confrontation with Russia and Iran, Assad's two main military backers. response, safe-haven assets such as U.S. Treasuries, gold and the yen bounced while emerging market currencies and shares slid.
"The initial implication has been a risk-off reaction. It's affected risk sensitive as well such as the Aussie," said Rodrigo Catril, currency strategist, National Australia Bank.
"We are watching oil prices as well. We have to see what Donald Trump is going to say later and any reaction from Russia is important too. It's a bit hard to have a view at this stage but a risk off turn is very evident."
Against the greenback, the Aussie AUD=D4 made a one-month trough of $0.7518 while the New Zealand dollar NZD=D4 held at $0.6961.
New Zealand government bonds 0#NZTSY= edged higher sending yields 2 basis points lower at the longer end of the curve.
Australian government bond futures gained too, with the three-year bond contract YTTc1 up 7 ticks at 98.22. The 10-year contract YTCc1 added 5.5 ticks to 97.4450. (Editing by Shri Navaratnam)
