The New Zealand dollar faltered against the yen after a US missile strike against the Syrian regime, sapping risk appetite and stoking demand for safe-havens such as Japan's currency and US Treasuries.
The kiwi fell to 77.05 at 5pm today from 77.17 at the start of the day, leaving it little changed from 77.04 on Thursday. The trade-weighted index was at 75.97 from 75.98 on Thursday.
Crude oil rose, US Treasuries rallied and the yen gained after US President Donald Trump ordered the first direct American military action against the regime of Syrian President Bashar al-Assad, with US warships firing as many as 60 Tomahawk cruise missiles at a Syrian Government airbase in retaliation for a gas attack on the town of Khan Sheikhoun.
News of the attack emerged as Trump prepared to meet his Chinese counterpart Xi Jinping at Trump's Mar-a-Lago estate in Florida, where trade and North Korea are expected to top the agenda.
"The day's excitement was indeed the missiles. It was a risk-off event - the yen was the sharpest mover, and US Treasuries," said Imre Speizer, senior markets strategist at Westpac Banking. Unless the reaction to the attack flares up again during London trading, "it seems to have stalled for now".
Traders were awaiting US non-farm payrolls for March, due for release overnight and expected to show the world's largest economy added 180,000 jobs last month, down from 235,000 in February. Speizer said there was a chance of a stronger number after figures from payrolls processor ADP showed US companies added 263,000 workers in March, the most since December 2014.
A strong number "might give the US dollar a push upwards", he said.
At 5pm today the kiwi was pretty much flat against the greenback at US69.75c.
It rose to 65.49c from 65.28c on Thursday after European Central Bank president Mario Draghi said there was no reason to change the bank's policy of ultra-low interest rates and bond buying.
It rose to 55.93 British pence from 55.82p and gained to A92.60c from A92.33c, as the Aussie dollar fell more sharply against the yen. The kiwi rose to 4.8111 yuan from 4.8073 yuan.
The two-year swap rate fell 1 basis point to 2.23 per cent, and 10-year swaps declined 4 basis point to 3.26 per cent.
