Z3229 – [BO] BO-HO Heating Oil Energy-Basis (Mean-Reversion)

Soybean oil and heating oil are both liquid fuels used in US transportation and heating. Heating oil (ULSD / #2 fuel oil) is the petroleum-derived distillate. Soybean oil is the biofuel feedstock for renewable diesel and biodiesel. Both are measured in USD per million BTU for energy-equivalent comparison. The signal reads the BO-HO basis on an energy-equivalent basis Z-scored on 36 years and tanh-bounded. When BO is cheap relative to HO (BO Premium Low), biodiesel/renewable diesel economics improve and demand for BO as feedstock rises. When BO is expensive (BO Premium High), biofuel economics weaken and BO demand softens. The signal is used TREND-FOLLOWING in BO Extremes Contrarian with polarity sign plus one. BO Premium Low (minus one, 42.4 percent of sample) delivers plus 3.45 percent BO forward returns (edge plus 1.90 pp, HAC t plus 2.24 significant at 5 percent). Today the signal reads at the 99.8th percentile in BO Premium High territory, 66 trading days in state, at the near-all-time extreme. Read on for the three cases that frame the signal, the state-conditional evidence, and the current reading in context.

What the chart is showing. The dark line in the top panel is the BO-HO energy-equivalent basis composite on a tanh-bounded plus-or-minus one scale — positive means BO is at extreme premium over HO (mean-reversion short-BO setup), negative means BO at extreme discount (mean-reversion long-BO setup). The bronze line in the middle panel is the CBOT Soybean Oil front-month in cents per pound. The bottom panel tracks the 252-day rolling information coefficient between the composite and BO 60-day forward returns. Dashed horizontal lines mark the plus-or-minus 0.2 moderate and plus-or-minus 0.5 extreme thresholds.

THE BIOFUEL-SUBSTITUTION MECHANISM

Renewable diesel and biodiesel economics depend on the relative price of feedstocks (soybean oil, tallow, UCO) versus the fossil-fuel alternative (ULSD/heating oil). When BO is cheap relative to HO, biofuel margins expand and feedstock demand increases, supporting BO prices. When BO is expensive relative to HO, biofuel margins compress and feedstock demand weakens, pressuring BO prices downward. The signal captures this via the energy-equivalent basis.

THE HONEST CAVEAT

Biofuel economics also depend on RINs (Renewable Identification Numbers) and tax credits (BTC, Section 45Z CFPC) that are not captured in the raw BO-HO basis. During periods of high RINs prices or strong tax-credit support, biofuel margins can remain positive even with elevated BO-HO basis. Readers should supplement with RINs pricing data for a complete biofuel-economics picture.
