West Texas Crude has been falling since breaking support at $75/barrel, following through below $50/barrel. A test of 2009 lows at $30/barrel is likely unless there is major disruption to supply.
When we adjust crude prices for inflation, they remain high by historical standards. Prior to the China boom of the early 2000s, the ratio of WTI Crude to CPI had seldom ventured above $20/barrel when measured in 1982-1984 dollars (shown as 0.2 on the chart below). After the dramatic fall of the last 3 months, the adjusted price at the end of December 2014 (in 1982-1984 dollars) is still $25.20/barrel (0.252 on the chart) — well above the former high.
