Wars are usually accounted for at the national level, in appropriations and deployments and carrier movements, because that is where the decisions are made and that is where the press conferences happen. Occasionally somebody does the less glamorous work of dividing the total by the number of kitchens. Moody’s chief economist Mark Zandi has put the cost of the war against Iran to the average American household at close to $2,000, and the breakdown is more interesting than the headline: roughly $1,100 of it energy, about $540 interest rates, and about $360 military spending.
That split deserves attention because it inverts the intuition. Most people assume a war shows up as a defence budget line, and that the household cost is therefore a tax question to be argued about later. In this accounting the Pentagon’s share is the smallest of the three. The largest is the pump, which is immediate, weekly and entirely non-negotiable for anyone who drives to work. The second largest is the mortgage and the car loan and the credit card, because sustained energy inflation keeps the central bank cautious, and a cautious central bank is an expensive one for anybody carrying a balance. The war is not mainly being paid for at the Treasury. It is being paid for at the forecourt and the refinancing desk.
This is the part where a good espresso explains the world. The posted price of a cup is never the cost of the coffee. It is the beans plus the rent plus the three-phase electricity plus the labour of a person who has to be there at six in the morning plus the capital tied up in a machine that cost as much as a car. Nobody itemises that on the menu, so customers argue about the beans and everybody involved knows the beans are not the problem. The Zandi arithmetic performs exactly this unbundling on a geopolitical event. The strikes are the beans. The rent is the interest rate. The electricity is the barrel.
The insight is that modern conflict has become a consumption tax that nobody voted on and nobody can opt out of. A tariff is visible, attributable and therefore politically answerable. A war that transmits itself through the oil price and the yield curve is none of those things. It arrives already blended into the cost of living, where it competes for blame with landlords, grocers, employers and the weather. That diffusion is not an accident of economics; it is the reason this kind of cost is so politically survivable. Voters who would never approve a $2,000 household levy for a Middle Eastern campaign will absorb the same amount without ever naming it, because it reaches them as fourteen separate annoyances rather than one line item.
What makes the figure useful is precisely that somebody bothered to reassemble it. Numbers like this change the register of the argument. A debate about strike authorisations is a debate about strategy, in which the public are spectators. A debate about $1,100 of fuel per household is a debate about the household budget, in which the public are the principals. The same facts, rearranged, hand the argument to different people. This is why the breakdown matters more than the total, and why the energy share being almost twice the interest share and three times the military share is the single most quotable thing in the whole estimate.
The forecourt, it turns out, is the most honest accountant in Washington. It posts its figures in numbers a metre high, updates them daily, and has never once been asked to testify.
