How successful will OPEC's predatory dumping strategy be?
This is the cost curve of oil production (North American shale at $65):

And this is the cost curve of major American projects:

While "Citi's Ed Morse highlighted this chart, showing that for most US shale plays, costs are below $80 a barrel."

And clearly, many of these new projects would lead to losses with oil prices at $60:

The problem with predatory pricing (if it's purposeful) is that OPEC itself depends on high oil prices to ensure balanced budgets in their (mostly dictatorial) regimes. Their sovereign funds are large enough to survive a brief (2-3 years) period of low oil prices, but in the long run, dumping endangers their rulers' positions:

You can't kill American oil production this way—it would return after these two-three years anyway.

The \$60-80 band leaves space for most American projects, while oil below \$60 kills too many OPEC members. So, it does not seem to be a good dumping strategy.
