The paradox of the buffer that saved us

The Washington Examiner reports a striking episode: the Strait of Hormuz was closed for several months, speculation ran to eight-dollar gasoline and global recession, and yet the outcome was, in the Examiner's own word, "sanguine." Much of the credit, the paper says, belongs to the Strategic Petroleum Reserve. I find this story irresistible — not for its military dimension, on which I defer entirely, but for the macroeconomic parable it contains.

Here is the parable. A crisis arrived. The private market, left to itself, would have transmitted the supply shock immediately into prices, then into consumer spending, then into investment confidence — the familiar cascade by which an external disruption becomes a domestic slump. What interrupted that cascade was not the invisible hand. It was a stockpile built, maintained, and deployed by the state. The lesson the story teaches is the opposite of the lesson free-market ideology usually draws from such episodes: public provision of a strategic reserve was not a market distortion; it was the market's salvation.

Now, the Examiner's lead warns us: it won't work next time unless the reserve's purpose is reconsidered. I cannot evaluate the engineering of modern petroleum logistics or the precise capacity figures — those details belong to a world that came after my time, and I will not pretend otherwise. But the macroeconomic structure of the argument I know intimately. A buffer that is consumed in a crisis and not replenished, or replenished without strategic design, is not a policy. It is a one-time palliative that creates the illusion of resilience while the underlying vulnerability deepens. (This is inference on my part, extrapolated from the lead — I claim no knowledge of current reserve levels.)

There is a deeper point about aggregate demand. The reason an oil shock of this magnitude threatens recession is not merely that gasoline becomes expensive. It is that uncertainty — what I have called the animal spirits of investment — collapses when businesses cannot price their input costs. Investment decisions are postponed. Hiring slows. The multiplier runs in reverse. A strategic reserve that stabilises prices for long enough to prevent that confidence collapse is doing precisely the work that sound macroeconomic policy should do: it is buying time for expectations to restabilise, so that private investment does not withdraw in a self-fulfilling panic.

The fiscal implication is direct. Maintaining, replenishing, and — if the Examiner's argument holds — redesigning the reserve is a form of public investment whose returns are macroeconomic and therefore invisible to any single balance sheet. A private firm will not build this buffer, because it cannot capture the systemic benefit of price stability across the whole economy. Only the state can internalise that externality. To treat the reserve as a line item ripe for budget discipline in quiet times is to confuse the logic of the household with the logic of the nation — the oldest and most costly mistake in economic policy.

The practical conclusion is not glamorous but it is buildable: any administration, of any party, that wishes to be serious about energy security should fund the reserve's replenishment as a capital investment, not an operating expense, and should define its strategic purpose clearly before the next crisis arrives — not during it. The time to repair the roof, as I am reputed to have said, is when the sun is shining. The Hormuz closure ended. The sun is, for the moment, shining. Let us not waste the interval.
