In Crude Oil, a cycle corresponding to approximately half of the Sunspot activity cycle (Sunspot Cycle 2H, ~2,007 days, or ~5.5y) appears to be present. The cycle is detectable through spectral analysis and was calculated using an astronomy-based model that accounts for the irregular duration of solar cycles.
Out-of-sample testing since 2020 shows that this variable solar-derived cycle maintains alignment with subsequent Crude Oil price movements.
