How do oil shocks spread beyond energy markets?

Answer: Energy costs feed into transport and inflation

Oil becomes a mood signal for everything — Not quite. Oil can influence sentiment, but that is not the main reason its impact spreads. The deeper mechanism is that energy is a real input into transport, production, and prices across the economy.

Only airlines and gas stations feel it — Partly right for the most visible examples, but far too narrow. Higher energy costs can affect logistics, manufacturing, food prices, and inflation expectations far beyond those sectors.

Energy costs feed into transport and inflation ✓ — Correct! Oil shocks spread because energy costs feed into transport, production, and inflation. Once that happens, the effects reach well beyond the energy sector itself.
