Wholesale diesel fell 33 cents. The top is holding.

California diesel closed Sunday at $8.3729, a second straight weekly decline and 6.6 cents under the September 22 record. Los Angeles wholesale diesel fell 33 cents, but distillate stocks drew again and gasoline sits 4.9 cents from the all-time state record at $6.3889. Our call for October 5 through 11.

Diesel confirmed the top. Gasoline is the new number to watch.

California diesel closed Sunday at $8.4160, the first weekly decline this cycle, and Los Angeles wholesale confirmed the top by rising just 13 cents. Gasoline went the other way, up 20 cents to $6.3528 and nine cents from the all-time state record. WTI fell 8% on Iran peace hopes while Brent held near $104. Our call for September 28 through October 4.

Another record Sunday, and we are calling the top

California diesel set another record Sunday at $8.4244 and seven of the nine Central Valley metros we track set records with it. But the Oman meeting was postponed indefinitely, which was one of the three things we said would prove us wrong, and the market topped anyway. Los Angeles wholesale slowed from 57 cents to 14, distillate built a third straight week, and Hanford and Merced already peaked midweek. We are calling the top and we tell you exactly what would break the call.

We called the $8 handle and got it, now we think the top is close

California diesel set another all-time record Sunday at $8.1367, and for the first time all nine Central Valley metros we track set records on the same day. But something changed Friday: crude fell, distillate inventories built for a second straight week, and Gulf diplomats sit down with Iran in Oman today. We think the wholesale top is close, and we say exactly what would prove us wrong.

We called the top and the market called our bluff

A Labor Day thank-you to the men and women of agriculture, the armed forces and our first responders. Then the market: US–Iran strikes resumed September 1, crude ran up 9%, the diesel crack set a record above $106 a barrel, and California diesel closed at an all-time high of $7.8105 with six of nine Valley metros setting records.
