A Toll on the Strait, a Tax on the World’s Poor

A statesman has announced that his country will “take over” the Strait of Hormuz, reimpose a naval blockade, and exact a twenty per cent toll on all vessels that pass. This narrow channel, we are told, carries about a fifth of the world’s daily oil consumption. The same statesman expects “reimbursement” from other wealthy nations that benefit from this traffic, and declares that his country cannot be expected to do this “for nothing.” His adversary replies that the strait is his territory; his paramilitary strikes “non-compliant” tankers. Both parties, a month ago, agreed to a memorandum promising the free flow of shipping. We now learn that this agreement has entered, with admirable frankness, a “state of crisis.”

When I wrote of the wealth of nations, I urged that we trace every policy to its effects on prices and on those who ultimately pay them. A toll of twenty per cent, laid upon a passage through which a fifth of the world’s oil must go, is not borne by admirals or ministers. It is translated, by the higgling and bargaining of the market, into dearer fuel, dearer carriage, dearer bread. The visible exaction falls on the ship; the invisible burden rests on the labouring poor in distant countries, who never voted in the councils that have made their candles and their bus fares more costly.

In that same work I argued that the division of labour is limited by the extent of the market. A blockade that cuts crossings through this strait by some great fraction, as is reported, does not merely inconvenience a few proud merchants; it narrows the effective market for innumerable trades. Refiners, carriers, shopkeepers, and artificers who build and repair their instruments all find their world shrunken. Whatever widens markets—roads, canals, secure sea-lanes—encourages industry and opulence; whatever fragments them throws society backward. A strait that should be a public highway has been turned into a private turnpike, and the natural progress of opulence is asked to halt at a toll-booth.

We are told this levy is the price of security, that a powerful fleet must be compensated for guarding commerce from attack. Yet the attacks now cited—the missiles, the drones, the “non-compliant” tankers—have followed closely upon the threat of renewed blockade and fee. Here self-interest responds, as it always will, to the incentives actually offered. One great power sees an opportunity to tax other people’s trade; its rival sees an opportunity to contest that claim and assert its own. Each appeals to justice; each maneuvers for advantage. A scheme that rests on the unusual meekness of rival states and armed factions is not a system of policy; it is a wish.

In The Theory of Moral Sentiments I proposed the impartial spectator, that disinterested judge whose sentiments we consult when we ask whether our conduct is praise-worthy, and not merely praised. What would such a spectator say of this arrangement, in which one nation declares itself “guardian” of a passage used by all, contradicts its own earlier doctrine that no state may charge such a fee, and then demands reimbursement from “very wealthy” allies? He might allow that defence is a proper public expense, that those who profit most by a secure sea might reasonably bear more of the charge. But he would observe, I suspect, that a tax set by the gun-deck, without the consent of most who will pay it, has more of extortion than of justice.

There is, moreover, the old problem of what I called a conspiracy against the public. When merchants or their statesmen speak of reimbursement, of doing nothing “for nothing,” they rarely mean to forgo their own advantage. The permanent interest of such projectors is to narrow competition, to make all who would trade pass under their arch and pay at their office. That such a claim now clothes itself in the garb of security and guardianship should not surprise us; the vilest maxim—“all for ourselves, and nothing for other people”—seldom goes abroad without a cloak. It deserves, as I once wrote of similar designs, the most suspicious attention.

Finally, we should beware the man of system who imagines he can arrange the great chess-board of human society from the quarterdeck. Here are many independent principles of motion: rival states, commercial republics, energy-hungry populations, restless armed corps at sea and ashore. To suppose that one decree—blockade at four o’clock, tolls “immediately”—will fix so many moving parts is to mistake ships for pawns. The memorandum for free passage is already mutilated; tit for tat strikes already multiply. The impartial spectator, looking down from a calmer height, would see in this toll not the wise management of an international highway, but another way of taxing the weak to flatter the power of the strong.
