The New Zealand dollar fell to a new three-week low as traders questioned whether the Reserve Bank's steps to lean on lending to speculative property investors will warrant a harder stance when the bank reviews interest rates on Thursday.
The kiwi fell as low as 73.24 US cents, trading at 73.31 cents at 5pm in Wellington from 73.60 cents on Friday in New York. the trade-weighted index dropped to 77.02 from 77.92 last week.
The local currency dropped 20 basis points after Prime Minister John Key said the Reserve Bank was looking at expanding its macro-prudential tools which would let interest rates stay lower for longer. The central bank last week said it's looking at ways to tighten rules around lending on residential rental properties to better reflect the risks, which some traders see as giving governor Graeme Wheeler more room to leave rates unchanged, or cut if need be.
"The risk is having announced them last week with such a short timeframe, he can lean on things more on Thursday," said Tim Kelleher, head of institutional FX sales NZ at ASB Institutional in Auckland.
The kiwi and Australian dollars were already under pressure in the Asian trading session after better-than-expected US jobs data stoked speculation the Federal Reserve will raise interest rates earlier than anticipated.
