The New Zealand dollar fell to its lowest level in more than a week against the yen after the Bank of Japan surprised the market by not expanding its monetary stimulus, rounding out a day of volatility tied to central bank actions.
The kiwi fell as low as 75.16 yen and was at 75.54 yen at 5pm in Wellington, down from 77.09 yen before the BOJ statement and from 76.37 yen late yesterday.
The local currency rose to 69.33 US cents, having surged after the Reserve Bank of New Zealand statement, from 68.81 cents yesterday.
The yen climbed against the greenback and the euro after the BOJ doused speculation it would add to its stimulus measures. Earlier, the Reserve Bank kept the official cash rate unchanged at 2.25 per cent and gave no indication it was in a hurry to cut interest rates, driving the kiwi up more than 1 per cent.
The kiwi was weaker at 6am, when the US Federal Reserve gave a mixed assessment of local and global conditions.
