Natural gas: Prices are heavily influenced by power demand, heating and cooling loads, storage levels, and LNG exports. Volatility is common, and short-term weather patterns can move prices sharply in either direction.
Crude oil: WTI and Brent respond to OPEC+ policy, non-OPEC supply growth, inventories, macroeconomic trends, and geopolitical events. Markets often trade in ranges, punctuated by price spikes or corrections as fundamentals change.
For planning and analysis, it is usually better to consider a range of price scenarios (low, base, high) rather than relying on a single-point forecast.
