The Commerce Commission has an investigation underway into the foreign exchange market, amid a global probe into alleged manipulation of currency rates.
The New Zealand regulator's active investigation into the currency trading market comes as at least a dozen authorities in North America, Asia and Europe conduct inquiries into claims traders colluded with their counterparts at rival banks to set foreign exchange rates by sharing client information.
The Commerce Commission has an "investigation in that space," a spokeswoman told BusinessDesk. She declined to comment on the scope of the probe or any of the parties involved.
The New Zealand dollar was the world's 10th most traded currency with US$105 billion in average daily turnover in April 2013 and accounting for about 2 per cent of the global US$5 trillion traded daily, according to the Bank for International Settlement. The bulk of trading in the kiwi occurs outside New Zealand.
The Australian Securities and Investment Commission joined the worldwide probe earlier this month, telling the Financial Times it would likely take a year to complete the investigation.
