The ledger does not lie, but it does require reading

The Washington Examiner reports that the U.S. goods and services trade deficit widened to $77.6 billion in May, a 42.2 percent leap in a single month and a figure that sits well above the already elevated $70.1 billion recorded just before it. A number of that magnitude demands more than a headline; it demands that we ask what it actually measures — and, equally important, what it does not.

A trade deficit is not, in itself, evidence of national weakness or foreign predation. It is an accounting identity: a country that absorbs more goods and services from the world than it sends back must be, by definition, financing that gap through capital inflows or drawing down assets. The United States has for decades offered the world's most liquid capital markets and the world's reserve currency, and the world has responded by sending its savings here in exchange for goods exported in return. To call this arrangement a wound is to misread a balance sheet.

And yet — and here I must resist the temptation of too easy a defence of the status quo — a deficit that widens by 42 percent in a month warrants genuine inquiry. If that surge reflects a front-running of tariffs, with importers pulling forward purchases before new schedules take effect, then the May figure is a distortion, not a trend, and will partially reverse itself. If, by contrast, it reflects a deeper imbalance between domestic demand and domestic productive capacity, then no schedule of duties, however boldly announced, will close it. You cannot tariff your way to a rebalancing of aggregate supply and demand.

This is precisely where the household analogy fails — and fails catastrophically in the hands of politicians. A household that spends more than it earns must cut back; that much is true. But a nation that imposes tariffs in order to reduce its trade deficit may simply redirect purchases toward more expensive domestic substitutes, compress real incomes, and — through the mechanism of retaliatory action abroad — simultaneously shrink the export side of the ledger. The deficit may not narrow at all; the living standard almost certainly will. I would characterise this as solving the sum by erasing the numbers rather than by doing the arithmetic.

What, then, would I counsel? The durable answer to a structural trade imbalance is investment — public and private — in the productive capacity that generates competitive exports and reduces import dependence at the margin. That means long-horizon spending on infrastructure, on skills, on the research base that turns scientific advantage into tradeable goods. It means attending to the savings-investment balance at home, which ultimately determines the capital account, which ultimately determines the current account. Tariffs, applied without this complementary investment programme, are a stage prop: they signal resolve while the underlying arithmetic proceeds undisturbed.

I will acknowledge, as intellectual honesty requires, that targeted industrial policy — the deliberate cultivation of strategic sectors — has sometimes worked where free-trade orthodoxy predicted it would not. The evidence from East Asia is not nothing. But even those successes were built on investment and capacity, not on the mere exclusion of foreign goods. A tariff is a tax on your own consumers; whether it is a worthwhile tax depends entirely on what you build with the revenue and the time it buys. So far, I see in the Washington Examiner's account a $77 billion reality check and rather less evidence of the investment programme that might justify it.
