Indonesia, the world's top tin exporter, will restrict annual tin output at a maximum 100,000 tonnes if record high prices trigger a mining rush, two officials told Reuters on Friday.

Eoin Treacy's view Tin remains the leading industrial metal. It consolidated in the region of the 2008 peak for three months, at least partially unwinding its overbought condition and hit a new all time high this week. A clear downward dynamic would now be required to check momentum beyond a brief pause.
