The Texas Petro Index declined in November and December 2018 on the heels of 23 straight months of growth, in response to dramatic declines in crude oil prices in the last 2 months of the year. Posted prices for West Texas Intermediate crude declined from a monthly average of more than $67/bbl in October to $45.31/bbl in December. Daily posted prices fell from a high of $71.75/bbl on Oct. 1 to a low of $39.25/bbl on Dec. 24.
