I am kind of 50:50 on my theory of which way the housewives will jump to be honest, it is the sword hanging over the head of the currency and will probably prevent any players from becoming too bullish on NZD at least until it becomes obvious as to whether they are a factor of not.
The other piece of the equation which I forgot to mention the other day was that on April 1st, the government increased the "Working for Families" tax rebates which puts another $100 a week into the hands of families. This is not a low income targeting initiative, it affects middle income earners, and is on top of what they were currently getting in tax rebates. I don't imagine this extra benefit will go into savings accounts - it will be spent on increased petrol prices, etc so will end up back in the economy, as do all social welfare benefits. This has to be viewed as positive for retail sales figures and potentially inflationary.
On top of this the banks have reduced their 2 year fixed mortgage rates for home buyers which has been the big problem for the Reserve bank.
All in all, lots of contrary factors at play. Banks have factored in a reduction in the interest rates and most are looking at June, but Bollard (RB governor) is a conservative bugga who probably regrets not raising interest rates sooner last year, so he will likely only drop them when he is absolutely certain he has a tight lid on inflation. The banks are maybe too optimistic at present as to when the interest rates willcome down.
Good luck.
