The New Zealand dollar is headed for a 2.1 per cent weekly decline against the US dollar, having hit a four-year low after the Reserve Bank on Thursday removed its bias for higher interest rates, saying the benchmark rate could go up or down.
The kiwi was at US72.80c at 5pm in Wellington, having touched a low of US72.28c yesterday morning, and from US74.36c at 8am on Monday. The trade-weighted index declined to 75.54 from 76.92 at the start of the week.
The New Zealand dollar tumbled this week after Reserve Bank Governor Graeme Wheeler's statement on Thursday morning that while he wasn't changing the 3.5 per cent benchmark rate, the future direction could be up or down as he monitored economic data.
Traders began to price in the chance of an interest rate cut, sending the kiwi sharply lower.
"The RBNZ was a bit more dovish than the market expected," said Martin Rudings, senior foreign exchange dealer at OMF.
