Scenario Background

WTI crude below $30/barrel represents extreme oversupply or demand destruction.

OPEC+ producers (particularly high-cost producers like Iran, Venezuela, Algeria) face fiscal stress at these levels.

Historical Context

WTI below $30 has occurred rarely: April 2020 briefly hit -$37 (front month contract expiry anomaly), 2016 saw $26 low, 2001 saw $17, and 1998 saw $10. The post-2014 period saw multiple dips below $30 as shale production forced price discovery. The 1986 collapse saw oil fall from $30 to $10 within months. Each sub-$30 episode has been relatively brief (6-12 months) as supply response followed.

What to Watch For

  • WTI below $30 sustained for 3+ months
  • OPEC+ production cuts announced
  • US rig count declining below 300
  • Energy HY defaults rising
  • Saudi Arabia fiscal stress signals
