NEW YORK: Cotton futures sank on Thursday under pressure from a selloff in other commodities markets, including grains, as the dollar rallied.

"Most of this is outside markets," said Peter Egli, director of risk management at British merchant Plexus Cotton.

Cotton contracts for July on ICE Futures US settled down 0.98 cent, or 1.6 percent, at 61.07 cents per lb. They traded within a range of 60.6 and 62.15 cents a lb.

The cash to second-month spread gained 0.12 cent to 0.2 cent per lb.

The dollar index was up 0.23 percent. The Thomson Reuters Core Commodity CRB Index, which tracks 19 commodities, was down 0.82 percent.
