If tanker owners were wondering how dire markets have been in recent months, Clarksons Research has just confirmed exactly how bad.

The research arm of shipbroker Clarksons said the average rate for the whole fleet was just $5,229 per day at one point in mid-January — the worst figure for at least 20 years.

For January as a whole, average earnings dropped to $6,295 per day — the second lowest level in the last two decades.
