The Canadian dollar fell back to parity with the US dollar after the release of their GDP numbers.
Growth last month was right in line with expectations but the data was more positive than negative given strong readings in both Q2 and Q3 GDP. Business investment led the rise, but goods and industrial production weakened in September which means that the latest numbers reflect the recent deterioration in the Canadian economy. The Australian and New Zealand dollars also sold off, but that was primarily due to a broad based dollar rally and drop in commodity prices because the Australian current account balance was actually stronger than the market’s forecast.
