Traders' Note

Weather-neutral SD balance (WNSDB) = production plus imports minus exports. Effectively, WNSDB shows the strength of the underlying supply relative to previous year.

  • When WNSDB is above zero, it means that net-supply is expanding in annual terms.
  • When WNSDB is below zero, it means that net-supply is shrinking in annual terms.

As a rule, the bulls want WNSDB to remain positive and trend up, while the bears want WNSDB to remain negative and trend down.
