   DAVENPORT, FL (DTN) -- Chicago CBOB basis strengthened Tuesday (4/22), 
narrowing to its tightest level in more than five months as the market 
transitions out of third-cycle barrels and into first-cycle positioning.

   CBOB for West Shore delivery was assessed at an 8.5cts discount to May NYMEX 
RBOB futures, up 9cts from the prior session when it was at a discount of 
17.5cts.  The current differential is the strongest since a 7.5cts discount 
assessed on November 14, 2025, according to DTN Energy data. Market chatter 
during the current session indicated values at around a discount of 5cts to 
6cts.

   Chicago pipeline CBOB is shifting out of Cycle 3 (C3) barrels, with the move 
toward first cycle (C1) positioning supporting prompt values as market 
participants adjust for tighter near-term availability.

   "Part of the move is tied to the cycle shift, but it also feels like someone 
needs barrels now," a source familiar with Midwest refined product trading said.

   The Buckeye Complex and Wolverine pipeline reflected similar strength, with 
CBOB basis assessed at an 8.50cts discount, narrowing by 6.25cts from the prior 
session, according to DTN data.

   Markets will be watching whether this strength carries into next week as 
trading fully transitions into first-cycle barrels.
