Suezmaxes are commanding around $44,000 per day on the spot market right now, according to Jefferies.

Clarksons says tight tonnage levels in West Africa and maintenance work at the port of Trieste, which has lifted congestion, have both aided the market.

The present rates compare with the year-to-date average of $24,564 daily for spot-trading suezmaxes, according to Clarksons.

Aframax rates were almost level with suezmaxes at $43,000 daily after rising by over 140% last week, Jefferies says.
