Energy, Commodities & Physical Supply Chain Desk Quantitative Architecture & Methodology

The Energy, Commodities & Physical Supply Chain Desk models real-world physical conversion margins, maritime transport friction, thermal power generation thermodynamics, and futures curve roll yield dynamics. Rather than treating commodities as synthetic paper bets, these models calculate physical refinery crude yields, heat rates (Btu/kWh), boil-off losses, and working capital carrying costs.

Core Mathematical Formulations

Refinery 3:2:1 Crack Spread (GRM) Mathematical Proof
$$\text{GRM}_{3:2:1} = \frac{2 \times P_{\text{Gas}} \times 42 + 1 \times P_{\text{Diesel}} \times 42 - 3 \times P_{\text{Crude}}}{3}$$

Standard industry benchmark measuring the gross processing margin extracted from cracking three barrels of crude oil into two barrels of finished gasoline and one barrel of ultra-low sulfur diesel.

Commodity Roll Yield Extraction Mathematical Proof
$$R_{\text{roll}} = \frac{F_{\text{front}} - F_{\text{next}}}{F_{\text{front}}} \times \frac{365}{D_{\text{days}}}$$

Quantifies the annualized structural carry earned by rolling long contracts down a backwardated futures curve or the persistent negative carry drag suffered in contango.

Power Grid Clean Spark Spread (CSS) Mathematical Proof
$$\text{CSS} = P_{\text{Power}} - (\text{HR} \times P_{\text{Gas}}) - (\text{EF} \times \text{HR} \times P_{\text{Carbon}}) - \text{VOM}$$

Calculates the net operating cash margin per megawatt-hour (MWh) generated by natural gas combined-cycle power plants after fuel combustion, variable maintenance, and carbon allowance compliance.

Tanker Floating Storage Net Arbitrage PnL Mathematical Proof
$$\text{PnL} = V \times (F - S) - (R_{\text{day}} \times D) - (B_{\text{day}} \times D) - \left(V \cdot S \cdot r \cdot \frac{D}{360}\right) - C_{\text{ins}} - C_{\text{loss}} - C_{\text{port}}$$

Closed-form underwriter determining the exact net cash profit from buying spot physical crude, chartering a VLCC/Suezmax supertanker for offshore floating storage, and hedging forward contract delivery.
