Feb. 9 (Bloomberg) -- Rents for iron-ore carrying Capesize ships may rise almost fourfold this quarter as slower speeds and strengthening demand buoy vessel usage, according to DNB Markets, a unit of DNB Bank ASA, Norway’s biggest bank.

Earnings for the vessels may advance to as high as $20,000 a day, DNB shipping analyst Nicolay Dyvik wrote in a report today. The vessels are making $5,233, according to the London- based Baltic Exchange.
