Copper, little changed, may gain today as a weakening US currency drives investors to purchase commodities as a hedge against accelerating consumer prices.

The US dollar hovered just above a 15-month low against a basket of major currencies hit on Wednesday, on the view that US interest rates will remain low well into next year.

The metal used in construction and automobiles may also gain after China's industrial production expanded the most in 18 months, adding to optimism the world's largest copper user will lead the global economic recovery.
