* The capesize index dropped 82 points, or 1.8%, to 4,456 points.
* Average daily earnings for capesizes, which typically transport 170,000-180,000 tonne cargoes such as iron ore and coal, declined $618 to $33,383.
* The panamax index fell 12 points, or 0.6%, to 2,121 points.
* Average daily earnings for panamaxes, which usually carry coal or grain cargoes of about 60,000 tonnes to 70,000 tonnes, fell $100 to $16,977 .
