SHanghai copper, zinc 4 pct limit down after close-out

SINGAPORE, Oct 10 (Reuters) - Shanghai copper fell by its 4 percent limit on Friday to its lowest in almost three years, despite a one-day suspension on Thursday and a forced ring-out, or closure of positions.

Zinc also fell by its limit. It had not not suspended.

Shanghai's benchmark copper contract SZNc3 fell 1,830 yuan at the open to 43,890 yuan, its weakest since December 2005. Zinc SZNc3 fell 495 yuan from Thursday's settlement to 11,825 yuan.

Both markets have hit their downside thresholds four times in five days since reopening after week-long Chinese holidays, chasing tumbling London futures which have plummeted by 18 to 25 percent in the past two weeks on fears of a global recession and slowing demand.
