Inertia in international finance is a powerful force in its own right. But loyalty programs built on one member’s permanent goodwill tend to look sturdiest in the years just before their members start reading the fine print.
On paper, a peg is refreshingly simple: fix your currency’s value to a stronger one, usually the dollar, sometimes the euro, and enjoy the borrowed credibility. Hard pegs lock the rate outright; soft or “crawling” pegs allow it to drift within a leash. Either way, the defending central bank has exactly two tools: burn through foreign reserves buying back its own currency when it weakens or blindly mirror the anchor country’s interest rate decisions, whatever domestic conditions might actually call for.
It is a simple system. It is also, on inspection, a fairly complete surrender of the instruments a state normally uses to run its own economy.
The Sales Pitch
To be fair to the arrangement, pegging has genuinely delivered for some. The Gulf states priced their oil in dollars and pegged their currencies to the same dollar, which insulated government budgets from the currency swings that plague less disciplined exporters.
Hong Kong’s Linked Exchange Rate System, running since 1983, turned the territory into a byword for predictability, drawing in capital that a freely floating Hong Kong dollar might never have attracted. Switzerland’s euro ceiling, imposed in 2011, bought its exporters and hoteliers several years of breathing room against a currency that otherwise wanted to appreciate itself out of the tourism business. Even the CFA franc zone in West and Central Africa, for all the baggage attached to it, has produced inflation rates its non-pegged neighbors can only envy.
None of this is anything. It is simply the entry price of a subscription whose real terms are printed in a font nobody reads, but is compelled to follow them anyways, for multiple reasons.
Importing Inflation: The Fed Sneezes, You Catch Pneumonia
Here is the fine print. A pegged central bank does not merely borrow the anchor currency’s credibility; it inherits the anchor’s monetary policy wholesale, timing included. When the U.S. Federal Reserve raises rates to cool an American economy that a Gulf or Hong Kong policymaker had no hand in overheating, the pegged state must raise its own rates in lockstep, regardless of whether its domestic economy is booming, stagnant, or in outright recession.
The reverse is just as damaging: when Washington keeps rates low for its own reasons, cheap borrowing floods into pegged economies and inflates asset bubbles that have nothing to do with local fundamentals. Ask any Hong Kong property buyer who lived through the last two decades; they will tell you, if they’re honest.
Michael Hudson, the economist most associated with tracing the plumbing of this system, has spent decades describing what happens on the other end of that arrangement. Central banks that peg to the dollar are structurally obliged to keep buying U.S. Treasury debt to defend their currencies, recycling their trade surpluses straight back into financing Washington’s deficits.
Michael Hudson calls the arrangement, without much affection, “the largest free lunch ever achieved in history.”A description that loses none of its bite decades after he first wrote it. Pegged nations do not just import American interest-rate decisions; they help bankroll the very deficit spending that generates the inflation they will later be asked to absorb.
What an amazing deal, right?
The Nuclear Option: Weaponizing the Dollar
If interest-rate shadowing is the peg’s chronic condition, sanctions are its heart attack. When Washington and its allies froze roughly $300 billion of Russia’s $640 billion in foreign reserves after February 2022, the message reached every finance ministry on earth simultaneously, whether or not they held a single ruble: dollar reserves are not really yours. They are yours to hold, at the pleasure of the country that issues them, and revocable the moment you fall out of favor politically.
Professor Richard Wolff, who has spent years cataloguing the fallout, argues the sanctions campaign was less a demonstration of American strength than a strategic own goal; it converted every dollar-holding government, pegged or not, into a hostage watching the exits.
Sanctions did not merely punish Moscow; they advertised, to Riyadh and Abuja alike, or anybody paying attention really, even if they can’t do anything to change the status quo, exactly what dollar dependence can cost a government that displeases Washington.
That the lesson landed is not really in dispute; it shows up in the flight toward gold that followed, and in the growing list of governments quietly asking their central banks the same unsettling question:
What happens to us if we’re next?
Bretton Woods: In, Sovereignty: Negotiable!
Strip away the technicalities, and a peg is, at bottom, an agreement to outsource the two levers every government normally uses to steer its own economy (the interest rate and the exchange rate), to a foreign central bank’s judgment.
Wolff traces the modern version of this bargain to the 1944 Bretton Woods conference, when an America producing roughly half the world’s industrial output simply had the leverage to insist the rest of the world tie its currencies to the dollar. It was not so much negotiated as imposed by circumstance, and the habit outlived the circumstance by decades.
Tellingly, the countries, most anxious about their own sovereignty, have drawn the obvious conclusion and stayed away. China rejected a flat dollar peg after 2005 in favor of a “managed float” against a secret currency basket, paired with capital controls tight enough to prevent the kind of speculative attack that ends pegs elsewhere.
Russia went further still, all but eliminating the dollar from its trade with China; more than 95 percent of that bilateral trade now settles in rubles and yuan. While building one of the largest gold reserves on the planet as a hedge, no sanctions office in Washington can freeze.
Taiwan, barred from IMF membership by Beijing’s diplomatic pressure and unable to count on an international bailout, rejects pegging to either the dollar or the yuan and instead hoards the world’s fourth-largest foreign exchange reserves as self-insurance.
When the states, most obsessed with guarding their sovereignty, all reach the same conclusion about pegs, that is not a coincidence worth ignoring.
Hong Kong is the deliberate exception that proves the rule. Beijing enforces strict capital controls on the mainland yuan precisely so it does not have to expose the mainland economy to global capital flows, and then lets Hong Kong’s own dollar peg absorb that exposure instead, using the territory’s roughly $569 billion reserve war chest as a shock absorber that keeps mainland reserves untouched.
It is less a contradiction of China’s sovereignty doctrine than a calculated use of someone else’s peg as a firewall, one Beijing is reportedly in no hurry to dismantle until the yuan is fully convertible enough to replace it outright.
Even the exception, in other words, is sovereignty by another route.
The Colonial Ledger: Updated
Nowhere is the inherited-empire flavor of pegging more undisguised than in the CFA franc zone, where eight West and Central African states (most of them former French colonies), still peg to the euro under arrangements historically guaranteed by the French Treasury.
The predictability is real; so is the price. A structurally overvalued currency makes African exports less competitive on world markets, and Nigeria, which sits outside the franc zone and generates well over half of ECOWAS‘s entire GDP, has openly treated the arrangement as a live instrument of French influence rather than a neutral technical fix, refusing to fold its economy into a planned regional currency it cannot control.
Hudson has made the broader version of this argument his life’s work: the post-war dollar system did not merely stabilize exchange rates; it functioned as an updated apparatus for extracting resources and cheap labor from the periphery while nominally independent nations were steered into austerity by the IMF and World Bank whenever their currencies came under pressure.
The CFA franc is simply the most literal, least deniable version of that pattern. A colonial currency arrangement that outlived colonialism by seventy years and counting, now rebranded, argued over, and defended by the same governments who once imposed it, and their local “agents” to be “Franc”. Pun intended!
When the Peg Breaks
The record is usually not outright grim at the outset, but it is instructive in the long run, and sometimes in the short-to-medium run.
Argentina’s 1991 dollar peg genuinely slew the hyperinflation that had gutted household savings, and then, as the dollar strengthened globally through the late 1990s, made Argentine exports too expensive to sell, drained the reserves needed to defend the rate, and collapsed in 2002, dragging roughly half the population into poverty on its way down.
Switzerland’s celebrated 2011 franc ceiling protected exporters for four years and then had to be abandoned overnight in January 2015, sending the franc rocketing upward and inflicting instant losses on anyone who had bet the Swiss National Bank would hold the line forever.
Pegs, in other words, do not fail gently. They fail the way dams fail, fine for years, then all at once, the fundamentals crack, and the Earth rumbles.
Is the Subscription Even Sustainable?
The more interesting question in 2026 is not whether pegging has costs; that argument was settled decades ago, but whether the entire dollar-centered architecture underneath it is still worth pegging to?
The signals are not subtle. The dollar’s share of global reserves has slid from roughly 71% at the turn of the millennium to under 58% today, according to IMF data, and central banks have now bought roughly 1,000 tonnes of gold a year for four straight years, double the previous decade’s average, with 89% of surveyed reserve managers expecting their gold holdings to keep growing and nearly three-quarters expecting the dollar’s share to keep shrinking over the next five years.
These are not “talking points,” they are “facts.” Period.
China’s mBridge cross-border settlement platform, built with the Bank for International Settlements before the BIS quietly stepped back from it in 2024 citing sanctions concerns, has already processed over $55 billion in transactions outside the traditional dollar-clearing system.
Riyadh and Beijing have spent years in intermittent talks over pricing oil sales in yuan, talks that remain more symbolic than transformative so far, but symbolism has a way of becoming policy once enough other symbols pile up alongside it.
Wolff’s forecast, uncomfortable as it may be for Washington to hear, is that the unwinding of these dependencies will not stay a foreign problem. As pegged and unpegged states alike diversify away from dollar reserves and settle more trade in their own currencies, the United States loses the ability to print money at will and export the resulting inflation abroad.
Meaning that inflation, instead, comes home.
He describes the American political class as largely still in denial about this shift, reaching for tariffs and coercion rather than adjusting to a world in which currency sovereignty is no longer Washington’s to dispense or withhold on a whim.
None of this points to the dollar peg collapsing next quarter; sixty-odd governments are not about to cancel their subscriptions en masse, and inertia in international finance is a powerful force in its own right. But loyalty programs built on one member’s permanent goodwill tend to look sturdiest in the years just before their members start reading the fine print.
A growing number of central banks, it seems, have finally gotten around to it.
Nobody claims to have a crystal ball, detractors and proponents of currency pegging alike. But according to – of all people – Herbert Stein’s self-evident quote:
“If something cannot go on forever, it will stop.”
Let me offer my apologies as I end on a Wall Street maxim that can be expanded beyond the trading arena:
“The trend is your friend, until the bend at the end.”
