Why this matters
Excess kurtosis (fat tails) means extreme moves occur more often than a normal distribution predicts. Gaussian risk models systematically understate tail risk for this asset.

Average Monthly Return
Seasonal Context
US driving season (Memorial Day through Labor Day) lifts gasoline demand and refinery runs. Atlantic hurricane season (June–November) threatens Gulf Coast refining. OPEC+ meetings (typically June and December) are scheduled volatility events. Q4 builds toward winter heating demand.
Risk Metrics.
Value at Risk, Expected Shortfall, and drawdown analysis
Interpretation: On 95% of trading days, the loss is expected to be smaller than 8.49%. On the worst 5% of days, the average loss (CVaR) is estimated at 12.06%. The 99% VaR captures more extreme tail events at 13.61%.
Estimated from 560 daily returns. Tail risk estimates improve with longer history.
Maximum Drawdown: 35.25%

Return correlations with economically linked assets
CL vs NG: 167 overlapping return observations
Note: Return correlations are unstable over time and do not imply causation. These pairs are shown because they share economic drivers (e.g., agricultural supply chains, energy complex), not because correlation alone is meaningful. Short-sample correlations (N < 250) should be treated as rough estimates.
Trend Analysis.

Bandwidth is expanding — the market is in a high-volatility regime. Large moves in either direction are ongoing.
About Crude Oil.
Fundamentals, catalysts, and Ethiopian trade relevance
Ethiopian Trade Relevance
Ethiopia imports virtually all its petroleum, making crude oil the largest single import by value. Oil price swings directly impact the trade balance, forex reserves, and domestic fuel/transport costs. The ETB/USD exchange rate is partly a function of the oil import bill.
Supply & Demand Fundamentals
Global production ~100 million bbl/day. OPEC+ controls ~40% of supply. US shale (Permian Basin) is the marginal producer. Strategic Petroleum Reserve releases are a policy tool. Contango/backwardation in the futures curve signals storage economics. Crack spread (CL vs. gasoline + heating oil) measures refining margins.
