Vol Selling in FX and Commodity Markets

Selling options in equities is a well-known trade: implied volatility tends to run higher than realized volatility, so systematically selling options and collecting the difference has historically been a profitable, if crash-prone, strategy. The same volatility risk premium shows up in currencies and commodities, but the drivers behind it are different enough that it isn't just "equity vol selling with a different underlying."

In FX, a large share of the volatility risk premium is concentrated around known event risk: central bank rate decisions, elections, and, historically, pegged or managed exchange rates that can snap violently when a peg breaks, as happened when the Swiss National Bank abandoned its EUR/CHF floor in 2015 and moved the pair over 20% within minutes. Selling FX options systematically therefore means being compensated most of the time for a risk that is dominated by rare, policy-driven jumps rather than the continuous market-crash risk equity vol sellers are pricing.

In commodities, vol selling interacts with strong seasonality, natural gas or agricultural options carry structurally higher implied volatility around planting, harvest, or winter-demand windows, and with physical supply shocks (a weather event, an OPEC decision) that don't have a direct equity analogue. Because these risks are less correlated with equity market vol, commodity and FX vol-selling programs are often used by institutional allocators specifically for diversification against equity-vol-selling strategies, even though both harvest a similar-looking premium.
