The Strait of Hormuz Is Not a Private Turnpike

We are told that the Strait of Hormuz, a channel through which a great portion of the world’s oil must pass, has been effectively shut and is now the subject of anxious negotiation. Iran and Oman, it seems, are working toward a temporary arrangement by which ships would enter on a route close to Iran and exit on a route close to Oman, while other states and international bodies look on and append their approbation. Yet even this modest reopening is said to be “subject to other conditions,” conveyed through intermediaries, while Iran’s own security council has declared the strait will not open until the United States “corrects its behavior.” The world’s commerce thus waits upon a moral lecture.

When I wrote my Inquiry into the Nature and Causes of the Wealth of Nations, I remarked that the division of labour, that great engine of opulence, is limited by the extent of the market. A narrow lane permits only a few carts; a broad highway sustains a caravan. In your age, the sea-lane through Hormuz is no mere road but a principal artery of the commercial body. To close it, or to open it only upon conditions, is therefore not a local inconvenience but a contraction of the market for every country whose industry depends upon cheap and certain carriage of oil. The pin-maker in a distant land, the seamstress, the driver of a modest vehicle, all find their employments cramped by a quarrel among princes over a strait they will never see.

We also read that, in the course of these negotiations, demands have been published, behaviors are to be “corrected,” and even, according to one report, fees of some 5 to 7 percent of the value of cargoes have been floated, though later language disavows any immediate toll. Whether such a particular scheme is ultimately adopted is less important than the temper of mind it reveals. To discover that one holds a narrow pass through which the world must travel is a sore temptation; the power to obstruct is so obvious, the sufferers so distant, that the toll seems to cost nothing to those who levy it. Yet every percentage point so exacted must in the end be paid by someone, somewhere, at the pump or in the price of bread.

In Wealth of Nations I urged that every regulation be traced to its effect upon prices, and that we ask who bears the unseen cost. Here the visible actors are statesmen, councils, and admirals; the invisible payers are the labouring poor across the globe, who have no representative at the table where routes and conditions are contrived. A temporary deal endorsed by councils and organizations may look, on paper, like prudent management of a dangerous passage. But if it builds into every barrel of oil a charge for political theatre, for prestige, or for what I once called the “juggling trick” of public credit and war, then we have only disguised a tax upon those least able to bear it, under the guise of high diplomacy.

One must add that it is not only merchants who conspire against the public. States, too, are societies of men pursuing interest, reputation, and security. When a powerful country demands that another “correct its behavior” before commerce may resume, and when the other seeks to use the closing or opening of a strait as a lever to extract concessions, each behaves according to a sort of political self-love. Such conduct is not monstrous; it is human. But the impartial spectator, of whom I spoke in The Theory of Moral Sentiments, would ask whether the suffering imposed upon innocent third parties is proportioned to the injuries complained of, or whether the quarrel has become an occasion for the vile maxim—“all for ourselves, and nothing for other people”—written upon the waves.

There is, moreover, a danger here of the man of system in naval dress. To arrange that ships must enter on one side of a narrow channel and exit on another, to bind their passage to lists of prior demands, to make the world’s energy supply depend upon the perfect execution of a single, delicate plan, is to treat the great commerce of nations as if it were a chessboard whose pieces may be moved at will. But every captain, every insurer, every refiner, every consumer has a principle of motion of his own. If the scheme neglects their incentives—if, for example, it underestimates the ingenuity with which traders will seek to evade danger or cost—it may not secure peace but merely shift risk into darker and less governable channels.

What then ought prudent states to do? In my time I held that government has a clear duty to provide those public works and institutions which, though of great advantage to society, could never return a profitable revenue to any private undertaker; safe lanes of commerce are among these. To patrol a strait against attack, to punish piracy, to agree reasonable rules of navigation—these are just employments of public force. But to keep the strait shut as a bargaining chip, or to reopen it only upon conditions unrelated to the peaceable passage itself, is to convert a public work into a private rent. If the invisible hand sometimes turns self-interested behaviour toward the public good, this is its dark reverse: a visible strait used to exact an invisible tribute from the world’s poor. The moral task of statesmanship is to resist that temptation, and to reopen that waterway as a road for all, not a toll-gate for the few.
