Some people smile all the way to the bank due to a spike in tanker market spottrates:
John Fredriksen and his friends gets richer due to Trupm’s unilateral sanctions imposed on companies that trade with, or carry oil for, Iran.Chinese companies are specially targeted as part of the trade war.
Will this in any manner help US shipping??
Yes, but only US persons, companies and institutions owning and/or operating tankers under foreign flags I would think.
The Jones Act market operate in a very different sphere from the world market and is not likely to be affected in any manner.
Did the Trump administration realize the effects of slapping sanctions on part of COSCO, the world’s largest shipping company?:
I suspect they just thought this would be a good bargaining chip in their trade negosiations with China in the best " Art of the Deal" (their Bible) fashion.
