Copper for delivery in three months on the London Metal Exchange fell as much as $82, or 1.5 percent, to $3,225 a metric ton - the biggest decline since April 15. ....... Other metals dropped on the LME. Aluminum declined $19, or 1 percent, to $1,870 a ton. Zinc slipped $16, or 1.2 percent, to $1,310 and nickel fell $245, or 1.5 percent, to $15,800. Lead declined $16, or 1.7 percent, to $935 and tin was down $60, or 0.7 percent, at $8,125.
With the US market appearing very strong (at time of writing) I wonder what BHP will do? Also, these drops appear to be because of china worries, not US interest rates.
