Pipeline outages and refinery shutdowns, partly caused by Midwest flooding, disrupted crude and fuel cash markets. The Ozark pipeline carrying up to 360,000 bpd was shut, and the WTI June/July cash roll fell to minus 40 cents a barrel.
Heavy rain in Oklahoma and Arkansas was expected to swell the Arkansas River.
Flooding that disrupts pipelines and refineries lowers crude demand at Cushing and weakens the WTI cash market. High river levels can also restrict barge movements on the Arkansas and Mississippi systems, raising grain freight costs.
After 19 past bearish logistics events, Crude Oil (WTI) moved a median -1.5% over 5 sessions (37% higher; middle half -6.6% to +2.3%), and +5.3% over 20.
