The capesize index gained 56 points, or about 7 percent, to 854 points.

The panamax index was up one point, or 0.17 percent, to 598 points.
Average daily earnings for panamaxes, which usually carry coal or grain cargoes of about 60,000 to 70,000 tonnes, increased $15 to $4,783.
Among smaller vessels, the supramax index was down one point at 552 points, while the handysize index remained flat at 347 points.
