The New Zealand dollar and several other regional currencies fell sharply yesterday after the US dollar spiked higher in response to China's 1.9 per cent devaluation of the yuan, which is expected to pave the way for a more market-led value for the currency.
The kiwi dropped by just under US1c to a low of US65.38c in response to the news, while there were falls of similar magnitude in the Australian dollar, the Singapore dollar and the South Korean won.
China's central bank had earlier described the move as a "one-off depreciation" based on a new way of managing the exchange rate that was more reflective of market forces.
"Since China's trade in goods continues to post relatively large surpluses, the yuan's real effective exchange rate is still relatively strong versus various global currencies, and is deviating from market expectations," the bank said. "Therefore, it is necessary to further improve the yuan's midpoint pricing to meet the needs of the market."
Talk of possible devaluation had been in the market, but traders were surprised by the magnitude of it, said Bank of New Zealand currency strategist Raiko Shareef.
