Stolt Tankers president Lucas Vos believes a rebounding global economy will lure MR tankers back to their core markets, leaving chemical carriers in the clear.

The Netherlands-based tanker arm of Norway's Stolt-Nielsen group said spot rates for its vessels dropped 6.5% in its second quarter ending 31 May.

However, speaking on a conference call with analysts, Vos said chemical trades are "jumping back" this year and will continue to do so in 2022.
