What if Saudi Arabia floods the market to crush US shale?
Riyadh abandoning cuts to flood the market and discipline US shale sends Brent into the forties; short Brent, long fuel-levered airlines, and a steep contango are the trades, with disinflation a tailwind for duration. The textbook analogues are the Mar-2020 Saudi-Russia price war and the 1986 market-share war, both of which crushed flat price and energy equities. Transmission: cheap crude transfers income from producers to importing consumers/airlines; forward angle: US shale breakevens are lower and hedged in 2026, so Saudi must push prices deeper and longer than 1986 to force the same supply response.
