(BLOOMBERG) — Economists are still hotly debating whether the oil crash has been a net positive for advanced economies.

Optimists argue that cheap oil is a good thing for consumers and commodity-sensitive businesses, while pessimists point to the hit to energy-related investment and possible spillover into the financial system.

A new note from Francisco Blanch at Bank of America Merrill Lynch, however, puts the oil move into a much bigger perspective, arguing that a sustained price plunge “will push back $3 trillion a year from oil producers to global consumers, setting the stage for one of the largest transfers of wealth in human history.”
