Oil prices have dropped about 30% from their highs this year so I would expect to see shipping costs come down at least a bit. Of course it's not like there's a lot of competition in the industry, plus int'l companies like OOPS and FailEx tend to buy futures contracts for fuel so it might take a while before they see the benefit. But US oil production was up by over 1M barrels per day this year IIRC and is expected to increase by .6-.7M through 2020. So as long as inflation remains low, shipping prices should improve.
