Healthier refining margins have boosted product tanker rates to their highest level since April, analysts and brokers report.

LR2s and MRs in particular have benefited from higher cargo volumes and activity.

Clarksons Platou Securities said these vessels are now "showing healthy signs".

"Spot tanker rates have improved of late, and while VLCCs have eased recently as charterers and owners prepare for the start of the December loading programme this week, product carriers have been gaining traction," analysts Frode Morkedal and Omar Nokta said.
