TREASURIES-30Y bonds lose a point, extend earlier losses

NEW YORK, July 6 (Reuters) - The price on U.S. 30-year Treasury bonds fell more than a point on Monday, extending losses as traders bet on further weakness in long-dated debt in advance of this week's $73 billion in coupon supply.

The 30-year U.S. government bond US30YT=RR was down 26/32 in price after briefly losing more than 1 point. Their yield, which moves inversely to price, was 4.36 percent, up from 4.33 percent on Thursday.
