Vitol Oil Derivatives Trader Yaoyao Liu to Leave Firm

The departure of a trader credited with generating billions is a reminder of how concentrated returns can be in commodity derivatives desks, and how quickly a single book's fortunes can reverse. The detail that losses hit the team's book for a second straight year, after Liu had already stepped back and begun planning retirement, suggests the pullback was structural rather than a one-off blip. For Vitol and its counterparties, the open question is how the desk is rebuilt and whether the firm's oil derivatives franchise retains the risk appetite that produced those earlier gains.
