Oil's round trip: how a war premium appears — and disappears

Brent spiked above $100 on a supply shock and has round-tripped most of the way back. The backwardation in the futures curve flagged the spike as temporary.

Our read

The move: Brent ran from about $71 before the late-February conflict to a ~$109 peak on March 9, then round-tripped to below $78 by mid-June as the parties reached an agreement to wind the disruption down, erasing nearly the entire war premium.

The tell: a supply shock like this typically pushes the futures curve into backwardation. When barrels turn scarce, the convenience yield of holding inventory now jumps, pulling near-dated contracts above later-dated ones. That is the textbook signal that the market treats the spike as temporary.

The takeaway: over the cycle a commodity is anchored to the cost of supply; a geopolitical premium is a deviation that mean-reverts once the disruption clears.

The war-premium round trip

Brent crude, 2026	Level
Before the conflict (early February)	~$71
Conflict peak (March 9)	~$109
After the agreement (June 18)	below $78

Brent price levels from market data; the mid-June drop followed reports of an agreement to reopen Persian Gulf shipping and restart halted output.

What it shows

Supply shock, then restoration: a major supply disruption spiked the spot price; the prospect of major producers restarting output collapsed it just as fast.
Backwardation as a signal: in a genuine supply scare the curve typically inverts toward the front, with the market pricing the spike as temporary rather than a new plateau. The round trip is consistent with that reading.

What to watch

Two-sided and fast: a fragile agreement can re-introduce the premium overnight, so commodity risk runs both ways.
The Fed angle: the FOMC turned hawkish on June 17 citing an energy-led inflation impulse. Oil round-tripped the next day, raising the question of whether the energy impulse the Fed leaned on was already fading.

The Level I lesson

Commodities are not valued by discounting cash flows, because a barrel of oil generates no income stream to discount. Over the cycle it is anchored to the marginal cost of supply, and a shock moves the near-dated price far more than the long-dated one. That is precisely why the curve tips into backwardation during a disruption: when physical barrels are suddenly scarce, the convenience yield of holding inventory now spikes, pulling the near-dated price above later-dated contracts. That cost-of-carry relationship, financing and storage set against the convenience yield, is core to both the Commodities and the Derivatives material. The premium in a commodity is a deviation from its structural price, and deviations, unlike trends, tend to revert.
