The gauge also fell short of its already weak preliminary result, raising another round of questions about the health of China, the world’s second-biggest economy. But analysts noted that the recent mass of data indicates that the global economy is still moving in the right direction.

"Broadly, the economy backdrop continues to move in a favourable direction and so any data to the contrary, even if it is data that was expected like the Chinese PMI data, is enough to get investors to perhaps take a step back and exercise a little more caution."
The Canadian dollar was up 0.24 of a cent at 91.31 cents US.
