A boost in transaction volumes, an uptick in the bulker market and a strong showing from its financial business all helped Clarksons push up profitability in the first half of the year.

The world's largest shipbroker saw pretax profit jump by one quarter to £21.9m ($28.5m) year-on-year in difficult shipping and offshore markets. 

Andi Case, chief executive of Clarksons, said: "As we see signs of a rebalancing across some of the shipping markets, we are optimistic in our ability to capitalise on the upturn in the markets when it occurs, whilst maintaining the strength of the underlying business.
