A summer slump in shipping markets has left average rates this month almost two thirds down on a year ago, according to Clarksons Research Services.

The cross-sector ClarkSea Index for the first half of August sat at $7,500 per day, 60% below the mini-peak of June 2015, the brokerage said in a report.

It comes with bulker rates down 21% year-on-year across the first seven months of 2016.
