Copper was steady on Wednesday, tapping into hopes that central banks will be stirred into action to boost global growth or at least to reveal their hands ahead of a ECB meeting on Thursday and U.S. jobs data on Friday.

3M CU on LME traded at $7,627 up 0.1 % from Tuesday when it ended down about 0.5 %, but Copper may decline for a second day after a report showed U.S. manufacturing shrank, fueling concerns about demand from the second-largest user.. U.S. manufacturing contracted for a third-straight month in August.
