Diesel's premium to crude and its supply-demand gauge have collapsed this year. The rout reflects weaker shipping-industry buying and a mild winter, and the novel coronavirus in China has deepened the slide through travel restrictions and weaker investor sentiment.
Lower diesel demand and a weaker crack spread reduce energy-linked costs for feed transport and processing, while weak sentiment spills into other commodities. The outbreak adds downside risk to fuel demand.
After 13 past bearish disease events, ULSD / Diesel moved a median -5.1% over 5 sessions (38% higher; middle half -6.3% to +1.2%), and -6.1% over 20.
After 32 past bearish disease events, Crude Oil (WTI) moved a median -5.2% over 5 sessions (13% higher; middle half -15.0% to -2.4%), and -5.7% over 20.
