Capesize spot rates are on course for a month-long rout as July comes to an end, sinking to their lowest in four months.

Baltic Exchange assessments of average capesize rates have fallen by 33% since the month began, on the back of low cargo volumes relative to lengthening tonnage lists.

The weighted average of spot rates across five key capesize routes fell by a further $265 on Monday to $21,411 per day.
