Why can war risk move oil prices before supply is cut?

Answer: Supply, shipping, and insurance risk get repriced

Each headline acts like a mini embargo — Not quite. Headlines matter, but markets do not treat every war update like an instant embargo. They react to how credible the threat is to supply, shipping, and insurance.

Prices wait for visible shortages — Partly right, but too late. Visible shortages matter, yet prices often move earlier, when markets start expecting disruption rather than waiting to count missing barrels.

Supply, shipping, and insurance risk get repriced ✓ — Correct! Oil prices can move before supply is cut because markets reprice future risk. If war raises the chance of disruption in production, transport, or insurance, prices can jump early.
