A Cambridge Environmental Data Science paper, published online 13 April 2022, examines whether climate model forecasts of ENSO can predict monthly returns for commodities produced in tropical regions. The authors are from CSIRO, Monash University and Macquarie University.
The study suggests ENSO forecasts could help anticipate price moves in tropical commodities, but it is academic research with no immediate supply change behind it. Its effect on near-term prices is minimal.
