Weekly Finished Gasoline supplied from the EIA for March 27.
The weekly finished gasoline supplied number from the EIA is down 28% from the three year average. The three year average for the corresponding week for the past three years was 9.293 million barrels per day. Last week it was 6.659 million barrels per day. That's equivalent to a decline of 11 million gallons of ethanol or 4 million bushel per day of corn.
Given that some states still haven't issued a "stay-at-home" order or like Florida, just did today, we won't know the real decline in gasoline consumption (& ethanol) for another week or so.
