The external front

A currency can win every battle inside its own borders — lawful, adopted, governed — and still be quietly strangled from abroad. This is the dimension the domestic plan keeps deferring, and it is the one that has actually decided the fate of every challenger to the dollar. The dollar’s dominance is not held up only by US statute. It is held up by an international scaffolding: the petrodollar arrangement of 1974 (Lesson 45), the Eurodollar market that exports dollar demand as debt (Lesson 44), the BIS in Basel where the central banks coordinate (Lesson 42), the SWIFT-and-correspondent-banking plumbing through which OFAC can cut any party off from dollar clearing, and the simple, unlegislated fact that oil, semiconductors, shipping, and the $600-trillion derivatives market are all invoiced and settled in dollars. A new currency that ignores this scaffolding is a currency that wins at home and dies at the water’s edge.

The first thing to see clearly is what these institutions can and cannot do. None of them can forbida new currency. The BIS cannot outlaw it; the IMF cannot veto it; the World Bank cannot enjoin it. What each can do is make using the new unit more expensive than using the dollar — through Basel risk-weighting that penalizes banks for holding it, through SDR-basket exclusion that hides it from the trillions in passive reserve capital, through dollar-denominated development debt that locks borrowers into dollar demand for a generation, and through the threat of disconnection from dollar settlement that has been deployed against Iran, Russia, and roughly ten thousand sanctioned entities. That reframing matters enormously, because it tells you the external problem is not a war to be won head-on — no challenger has the leverage for that — but a switching cost to be made worth paying.

The question of capture: do you have to seize the commanding heights?

Here is the sharpest version of the problem, and it is the one worth dwelling on: the people who run the great dollar-denominated industries — oil majors, the payment networks, the multinationals whose entire cost and revenue structures are dollar-denominated — have no reason to cooperate and every reason to keep invoicing in dollars and to keep pressing their customers and counterparties to transact in dollars too. You cannot persuade them; their incentives are fixed against you. So is some form of capture and redirection of currency flows in oil, technology, and taxation necessary? The honest answer is: not coercive seizure, which would be lawless and would invite the capital flight and trade war the final lesson catalogs — but yes, you must capture the settlement of flows you actually control, because that is the only thing that has ever made a rival currency stick. This is precisely what the 1974 oil deal did for the dollar, and it is why the user’s instinct about oil contracts is exactly right.

The mechanism is network effects, run deliberately. The world holds dollars because it must buy things priced in dollars; if it must buy something it cannot do without — and pay for it in your unit — it must hold your unit. The flows a US-based conversion could actually anchor are real and not trivial: the United States is now the world’s largest producer of oil and natural gas, the largest LNG exporter, a dominant force in the chokepoints of advanced computing (the ASML–TSMC alliance and the export-control regime, Lesson 39), and the single largest buyer on earth through its own government procurement. Require US energy exports to settle in the new unit; make federal taxes, tariffs, and procurement payable only in it; price the export chokepoints you genuinely control in it. Each of these turns the chartalist lever (Lesson 80) outward, manufacturing external demand from flows that do not depend on any foreign company’s goodwill.

The treasury approach: respect is downstream of a safe asset

Demand-pull alone, though, is a coercion racket the world will route around the instant it can — the moment another energy supplier offers dollar pricing, the captured flow leaks away. Durable respect requires the second leg, and it is the one most reform fantasies omit: a deep, liquid, transparently-governed sovereign debt market in the new unit — a “new Treasury” — so that the surpluses the world earns by selling to you have somewhere safe to be parked. This is the real moat under the dollar. Foreign central banks do not hold dollars because they love America; they hold Treasuries because the US Treasury market is the deepest, safest, most liquid place on earth to store a national surplus. A challenger that wants respect must build that asset: a credible fiscal rule behind it (Lesson 79), free convertibility, rule-of-law contract enforcement, and an issuer insulated from the politicians who would debase it (Lesson 81). Ratings and index inclusion — the gates the agencies and benchmark providers guard — are simply downstream measurements of whether that safe asset is real.

Which surfaces the deepest strategic choice of the whole conversion, and the one to settle before T-day: how much of the world’s monetary plumbing do you actually want to carry? Full reserve-currency dominance is not only a privilege; it is the Triffin burden (Lessons 57, 76) — the persistent trade deficits and the hollowed-out tradable sector that supplying the world’s safe asset structurally requires. A currency built to realign domestic incentives may not want that bargain at all. It is entirely coherent — and probably wiser — to aim for a deeply respected currency: convertible, trusted, demanded for the energy and trade it anchors, holding a credible safe asset, and yet deliberately short of the reserve-hegemon role that started the entire distributional problem this curriculum set out to diagnose. The dollar’s global throne is not obviously a prize. Sometimes the point of leaving a house is not to build a bigger one.
