While the Opec and its Russia-led allies are widely expected to extend, or even deepen, their crude production cut well into next year, tanker owners may not have much to worry about.

Based on Alphatanker projections, the US, Brazil, Norway, Canada and Guyana together will increase their supply by 2.2m barrels per day (bpd) in 2020. That would support tonne-mile demand for crude tankers even with Middle Eastern exports hampered by the Opec cut.
