Dec 3 (Reuters) - The Baltic Exchange's main sea freight index rose for an eighth straight session on Tuesday, supported by stronger rates for capesize and panamax vessels.
* The Baltic index, which tracks rates for capesize, panamax and supramax vessels that ferry dry bulk commodities, increased 38 points, or 2.4%, to 1,606 points.
* The capesize index gained 119 points, or 3.7%, to 3,350, its highest since Sept. 26.
* Average daily earnings for capesizes, which typically transport 170,000-180,000 tonne cargoes such as iron ore and coal, increased $709 to $25,202.
* Higher demand from China for large-scale infrastructure projects could cause an increase in iron ore cargoes in 2020, Allied Shipbroking said in a note on Monday.
* The panamax index gained 33 points, or 2.6% to 1,315 points, its highest in more than three weeks.
* Average daily earnings for panamaxes, which usually carry coal or grain cargoes of about 60,000 tonnes to 70,000 tonnes, rose $264 to $10,532.
* The supramax index edged up 6 points to 825 points, registering its tenth consecutive session of gains. (Reporting by Anjishnu Mondal in Bengaluru; Editing by Maju Samuel)
