The losers in this scenario would be aircraft manufacturers, which have built up record backlogs on a cocktail of high fuel prices, low cost of capital, and new technology. Lower oil prices mean new aircraft models promising 15-20% fuel consumption reduction are not as attractive from a financial perspective. Coupled with the current trend of increasing cost of capital, this could mean a wave of cancellations of sexy new aircraft models. Or it could mean manufacturers need to revisit pricing assumptions. What is a fair price for a new widebody like the Boeing 777X, for example, in an $85/barrel world where its annual fuel cost falls by $3-4 million?
