A lack of vessels willing to load Russian crude has pushed up aframax rates to more than $350,000 per day from Primorsk.

Vessels are being fixed at a whopping Worldscale (WS) 715 — or $351,902 — from the key Baltic Sea port, UK shipbroker Howe Robinson said.

This is up from $332,000 last week and compares to a year-to-date average of $107,000.
