The weaker-than-expected data, along with continued uncertainty over the US political stalemate, has put downward pressure on the Aussie dollar, Bank of New Zealand currency strategist Mike Jones said.
Republicans and Democrats failed to agree on a temporary deal to raise the debt ceiling over the weekend and have just three working days left to reach agreement before the October 17 deadline.

“Both of those tend to raise concerns about global growth and both of those concerns have taken a pretty sharp toll on the Aussie dollar which has opened the week about half a cent lower.”
