Rudings expects the New Zealand dollar to trade in a range of US73.50c to US74.40c in coming days. The biggest event may be the minutes of the last Federal Open Market Committee and any sign the Fed will become more hawkish now that former chair Janet Yellen has stepped down.
The minutes may be relatively upbeat about the US economy, Rudings said. The Fed may hike three times this year while traders are only pricing in 2.5 hikes, and there was a risk "it may slip in a fourth hike".
