Gold settled higher on Wednesday as palladium prices hovered near their highest level since early 2001, benefiting from a five-month strike in South Africa and strong demand from the auto sector.

Palladium has risen 20 percent so far this year, underpinned by supply worries after a South African strike over wages took out 40 percent of global platinum output and hit the domestic economy. The country is the world's second-biggest producer of palladium.
