The Reserve Bank has confirmed it intervened in foreign exchange markets last month in an attempt to push the currency lower without giving any details on the size of its action, having already given a serve to the counter-balancing strength in the housing market earlier today.
"That intervention will not materially change the level of the exchange rate but could take potentially the tops off rallies," governor Graeme Wheeler told Parliament's finance and expenditure select committee. "In terms of activity, there's been an intervention."
The kiwi sank to 83.63 US cents from 84.48 cents before the comments were telegraphed at the committee in Wellington. The trade-weighted index fell to 77.71 from 78.18. The size of the bank's action would show up on its balance sheet, deputy governor Grant Spencer told the same meeting.
Wheeler outlined the criteria for the bank to intervene in a February speech to the New Zealand Manufacturers' and Exporters' Association, saying he would act "when circumstances are right." The central bank last intervened in mid-2007 when it sold a net $2.2 billion over two months.
"The Reserve Bank's MO is to trim peaks and troughs - it's really about slowing the pace of appreciation," said Sue Trinh, currency strategist at RBC Capital Markets in Hong Kong. "It's not particularly surprising, particularly given Wheeler paved the path" with a speech in February.
