Aussie hits 3-week low
In currencies, the Australian dollar dropped to a 3-week low after soft Australian inflation data paved the way for a further interest rate cut, possibly as soon as the central bank's November 3 policy meeting.
"You have to say data like this coupled with what the banks have done recently with the tightening up in conditions must increase the risk of a move before year end," said Su-Lin Ong, a senior economist at RBC Capital Markets. She was referring to Australia's major banks raising their variable mortgage rates to offset more stringent regulatory capital requirements.

The focus fell on the Fed's stance after the European Central Bank opened the door last week for more easing and China cut rates and banks' reserve requirements.
"While it can be argued that stimulus abroad is good for US markets and makes it easier for the Fed to raise interest rates in December, the reasons why these central banks are easing and the consequences for the dollar could also deter them from tightening," said BK Asset Management's Lien.
