NZD/USD dropped just prior to the RBA announcement
AUD/USD had lost a little bit of ground after the data earlier today, but the kiwi had hung in there.
So maybe it was a bit of 'catch up' (catch down more like).
There is no fresh news - plenty of politics related as a new PM is sought (John Key announced his resignation yesterday).
From what I've heard it was a few bids removed in precaution ahead of the RBA announcement, and a seller coming in, and then the stops that remained became more in danger ... and down we went.
Its staging a bit of a bounce as I update:
Low around 0.7095 on the spike down.
