KEY POINTS
  • Crude is tracking for its worst first half in at least 20 years.
  • Gartman, a big commodities player, says a bounce is possible, but there's more pain in store.
  • The downturn "may be a black swan for the oil industry itself, but it's a white swan or the economy in general," he added.

Crude oil has officially entered a bear market, and Commodities king Dennis Gartman told CNBC the pain is far from over.

In a recent interview, the editor and founder of The Gartman Letter said oil conglomerate OPEC was losing the war on oil, especially in light of the ascension of Saudi Arabia's new crown prince, Mohammed bin Salman. Crude oil is down nearly 20 percent in 2017, and is tracking for its biggest six-month drop since the late 1990s.
