MR tankers in the Atlantic finished the week on a high note, but how much higher they can go depends on competing factors on either side of the ocean.

The Baltic Exchange’s Atlantic basin time charter equivalent rate assessment skyrocketed by nearly $20,000 in four days, rising from $36,176 per day on Monday to close the week at $56,016 per day on Friday. The jump represents a 52.3% jump compared to the close of the prior week.
