Why the Dollar Milkshake Theory Still Holds in 2026

The instinct is understandable. Watch the US pile on debt, watch the political dysfunction, watch the dollar’s reserve share tick lower quarter after quarter, and the conclusion writes itself: dollar dominance is ending. The problem is that the conclusion is wrong, or at least it is asking the wrong question.

The Dollar Milkshake Theory, developed by macro strategist Brent Johnson, makes a counterintuitive claim. In a global financial system where every major economy is structurally compromised, the least compromised wins by default. Not because it is well run. Because the alternatives are worse, and the plumbing routes capital toward it regardless of preference.

This is not a cheerleading exercise for the United States. It is a mechanistic argument about how capital physically moves through a dollar-centric system under stress, and why that movement tends to favour US assets whether or not conditions in America are improving in absolute terms. The framework has accumulated a partial validation track record through the 2022 central bank intervention episodes.

Here is what the data and those 2022 episodes actually tell you about whether dollar dominance is eroding or entrenching, and the cognitive traps that lead investors to misjudge relative strength.

The mechanics behind the milkshake: how a dollar-centric system generates its own gravity

Start with a number that frames everything else. As of Q1 2026, the US dollar accounts for 57.13% of allocated global foreign-exchange reserves, according to IMF COFER data. The nearest rival, the euro, sits near 20%.

That gap is not sentiment. It is structural plumbing. The global financial system physically routes most cross-border transactions through dollars, which means any capital moving across borders is already touching the mechanism this theory describes.

Five structural forces sustain that centrality, and institutional research through 2026 keeps returning to the same list:

• Network effects. Dollar usage in reserves, trade invoicing, and finance is self-reinforcing, and once embedded, the cost of switching is high.
• Depth and liquidity. The US Treasury market and US capital markets remain the deepest and most liquid globally, making them the default destination for risk-off flows.
• Safe-haven and rule-of-law appeal. Perceived asset safety and legal protection are advantages most challengers lack.
• The outstanding dollar debt stock. A large volume of dollar-denominated debt sits outside the US, and servicing it requires dollars regardless of the borrower’s preference.
• Petrodollar recycling. Energy revenues settled in dollars have historically flowed back into US assets, a slow-moving background condition.

Total global FX reserves stand at roughly $13.1 trillion in recent quarters. Beyond reserves, BIS-referenced figures cited in institutional commentary put the dollar in approximately 89% of FX market turnover, a figure flagged as unverified in the source but consistent with the transactional picture the reserve data paints.

The outstanding debt stock deserves particular attention because it creates a self-reinforcing demand loop. Foreign entities that borrowed in dollars must acquire dollars to service those obligations, and when dollar funding tightens, that demand does not soften. It intensifies. The system generates its own gravity.

The relative game: why “bad” does not mean losing

The framework does not require the US to be well run. It requires the US to be less structurally compromised than the specific alternatives, not measured against an ideal.

Johnson frames it as an anonymised competition. When you strip the country names off and compare only the economic challenges, the US does not automatically look like the worst-positioned nation. The distinction that decides the contest is currency issuance. A country carrying debt in a currency it cannot print faces a categorically different problem under stress than the US, which issues the currency its debts are denominated in.

That is the point non-obvious to most investors. Criticising US policy competence tells you nothing about where capital flows. The architecture does the routing.

What 2022 proved, and what it did not

The theory stopped being hypothetical in 2022. That year, four major central banks were each compelled to intervene in their own markets, and the sequence in which the stress arrived followed the mechanism closely. When the Federal Reserve tightened, dollar scarcity radiated outward and exposed structural weakness at the periphery first.

Consider the episodes in order:

1. The UK gilt crisis. Following the September 2022 mini-budget, long-dated gilts sold off sharply, sterling weakened against the dollar, and the Bank of England was forced to intervene to stabilise the market.
2. Japanese yen weakness. With the Bank of Japan holding yield-curve control while the Fed tightened aggressively, the yen depreciated substantially, eventually prompting Japanese authorities to intervene directly in FX markets.
3. The euro-area energy shock. During the 2022 energy crisis the euro fell to parity against the dollar, and the European Central Bank introduced its Transmission Protection Instrument to manage sovereign-bond fragmentation risk.
4. Emerging-market distress. Weaker, dollar-dependent economies including Sri Lanka and Pakistan experienced reserve depletion and debt distress as global dollar rates climbed.

Each episode illustrates the same underlying dynamic. US monetary tightening tightened conditions everywhere, and the defensive response came from other central banks reacting to Fed policy rather than leading with their own agenda.

Johnson’s own assessment is that the Bank of England, the Bank of Japan, the ECB, and China’s central bank were each forced to act in 2022, bringing global conditions close to a crisis scenario without one fully developing.

That characterisation matters for what you take from it. The mechanism worked. The catastrophe did not arrive.

Partial validation, not full confirmation

Be precise about the scorecard. The capital-flow bias toward the US was confirmed. The defensive interventions abroad were confirmed. What did not materialise was a full sovereign debt crisis of the kind the theory’s more dramatic framings anticipated.

Proponents argue that difference is one of degree and timing rather than kind. That is a fair defence, but it is also exactly the sort of claim you should hold loosely. For an investor entering 2022, the practical value was real: the framework gave you a structural explanation for persistent dollar strength and for why foreign central banks were reacting rather than dictating. That is positioning context, not prophecy.

Comparing the balance sheets: why the US wins the ugly contest

Run Johnson’s anonymised exercise yourself. Strip the names off the balance sheets and look only at sovereign debt-to-GDP ratios among the major economies, drawing on the April 2026 IMF Fiscal Monitor.

The US ratio at approximately 126% is elevated, and the framework treats it as a legitimate monitored risk. But it is not exceptional. Japan carries 204%, France sits near 118%, and the economies most often nominated as dollar alternatives are hauling comparable or heavier burdens.

The decisive difference is currency issuance. The US carries its debt in a currency it can issue, which is categorically different from carrying debt in a currency you cannot control, particularly when funding conditions tighten.

Johnson’s principle: remove the country names, compare only the challenges, and the US does not automatically appear as the worst-positioned. Aggregate the advantages, and it becomes easily identifiable.

One qualification is warranted. Earlier Milkshake commentary leaned on a US inflation advantage over peers, and that gap has narrowed. US CPI near 3.5% in July 2026 now sits above several peers rather than below them, so the inflation leg of the argument requires care in the current environment.

The reserve data carries its own texture too. OMFIF characterised Q3 2024 as a multi-decade low near 57.4%, before a Q4 2024 rebound to 57.8%. Slow erosion and short-term rebounds can coexist. What this tells you is that benchmarking the US against an idealised alternative, rather than the real ones on this table, risks moving capital toward peers whose structural position is no better.

The cognitive traps that lead investors to misread the dollar’s position

Two opposing biases push investors toward the same mistake: a misjudgement of relative strength anchored in what they want to see rather than what the mechanics predict.

The first is proximity bias. Johnson observes that US-based investors overweight the domestic problems they can see directly and assume conditions must be structurally better somewhere else, without rigorously examining those alternatives. Distance flatters the foreign economy.

The second is the inverse error: misplaced optimism about dollar challengers. Legitimate grievances about the current system, sanctions risk, fiscal excess, get channelled into faith in BRICS arrangements or gold-linked settlement without an honest accounting of what those alternatives can actually deliver.

The evidence against the optimistic case is not rhetorical. Despite years of sustained internationalisation, alternative payment infrastructure, and energy deals settled in renminbi, the currency’s share of allocated global reserves sits at roughly 2%, unchanged in recent data. That stagnation tells you the structural barriers to displacing the dollar are empirically observable constraints, not talking points. Bearishness built on BRICS narratives alone is not rigorous analysis.

IMF and Federal Reserve assessments in 2025 reinforce the point, characterising de-dollarisation as gradual and fragmented rather than a near-term systemic break. The corrective principle is straightforward: evaluate what the system mechanics will produce, not what you wish would happen.

The IMF and Federal Reserve characterise current de-dollarisation trends as gradual and fragmented, a drift into smaller non-traditional currencies rather than a coordinated migration toward any single challenger, which is precisely the distinction the Milkshake framework predicts.

What would actually change the equation

The framework is not immune to reassessment. Four conditions would demand it, and they function as a monitoring checklist rather than a warning of imminent risk:

• A sustained US fiscal confidence shock, where investors seriously doubt the safety or real-return profile of Treasuries.
• Coordinated, accelerated de-dollarisation among major reserve holders, moving faster than the current gradual pace.
• Erosion of petrodollar arrangements, where large energy exporters durably price and settle outside the dollar.
• Institutional or political shocks that undermine US rule-of-law perceptions or capital-account openness.

Petrodollar arrangements represent one of the four monitored breakdown conditions in the framework, and while energy revenues settled in dollars have historically recycled into US assets, the durability of that channel depends on Gulf state pricing decisions that are now under active geopolitical pressure.

None of these has materialised through the data available to Q1 2026. The task is to track whether any is developing, not to assume they are already present.

What the data through 2026 actually confirms, and where the framework requires watching

Pull the threads together and the verdict is neither triumphant nor dismissive. IMF COFER, the Federal Reserve’s 2025 institutional research, and the 2022 intervention episodes collectively affirm that the structural mechanisms this theory describes remain intact as of Q1 2026, even as marginal erosion continues.

The dollar still commands 57.13% of allocated reserves, and the Federal Reserve’s 2025 review put the figure near 58%, far exceeding every alternative. The IMF frames what diversification is occurring as a gradual drift into a basket of smaller, non-traditional currencies, not a migration toward any single institutional challenger.

The US fiscal trajectory is the variable most likely to stress-test the framework’s core claim, because a sustained confidence shock in Treasuries would shift the system’s risk-off routing in ways that no current reserve share data can anticipate.

That distinction is the one that matters for positioning. The erosion is measured in years and decades, not quarters, which means near-term portfolio decisions should not be driven by the erosion narrative unless you hold a specific thesis about which breakdown condition is developing.

Separate the noise from the signal. Short-cycle dollar fluctuations generate headlines; the structural capital-flow bias operates over a far longer cycle and does not reverse on quarterly data. To assess whether the framework remains operative, track four variables:

• The dollar’s share of allocated reserves in the quarterly IMF COFER release.
• The US fiscal trajectory and real-yield dynamics.
• The pace at which emerging-market and BRICS de-dollarisation infrastructure actually scales.
• Any sign of accelerated official reserve diversification beyond the current gradual pace.

For investors in mining and energy, this is not abstract. The commodity complex is priced and settled in dollars, so whether dollar dominance is structurally entrenched or genuinely fragmenting sets the macro backdrop for capital allocation, hedging, and cross-border decisions. The framework does not hand you the answer for all time. It hands you the right questions to keep asking.

For readers wanting to translate the structural framework into specific portfolio implications, our dedicated guide to dollar reserve dominance and investment implications covers how capital allocation, hedging, and cross-border exposure decisions shift across different scenarios for reserve share erosion.
