Real Trade Unit  ·  Est. 2024

The sovereign price of
everything

For 80 years, the dollar has set the price of every trade, every import, every debt. Not because it is right. Because no one built a better measure — until now.

Every attempt was killed,
captured, or incomplete

The problem was identified in 1944. Seven serious attempts followed. Every one failed — not because the idea was wrong, but because the mechanism didn't exist. Until now.

1944 · Bretton Woods
Keynes Proposes the Bancor
John Maynard Keynes, Britain's greatest economist, arrives at Bretton Woods with a neutral global reserve unit he calls the Bancor. It would price trade on economic reality, not political power. The United States delegation buries it. The dollar wins. The world is told to be grateful.
Killed by geopolitics
1960 · Triffin Dilemma
Robert Triffin Proves the System Is Broken
Yale economist Robert Triffin demonstrates mathematically that any single nation's currency cannot serve simultaneously as global reserve and domestic policy tool without eventual breakdown. He was right. No mechanism was built. The dilemma became permanent.
Diagnosed, no cure built
1969 · IMF
Special Drawing Rights Issued
The IMF creates SDRs as a synthetic reserve asset. But the basket is politically weighted — dollar, euro, yuan, yen, pound. It measures influence, not economic fundamentals. The Global South receives a fraction. Borrowing still happens in dollars. Nothing changes at the dock, the port, or the factory floor.
Political basket, not measurement
1971 · Camp David
Nixon Closes the Gold Window
Without warning, President Nixon ends dollar convertibility to gold. The dollar becomes backed by nothing but trust — and the power to enforce that trust. Every nation's reserves, every trade contract, every sovereign debt invoice is now priced in a currency tied to American political decisions, not global economic reality.
Reserve currency becomes political weapon
2009 · Beijing
Zhou Xiaochuan Proposes SDR Reform
In the depths of the financial crisis, China's central bank governor calls for a supranational reserve currency reformed from SDRs. The proposal is serious, the urgency real. But no neutral issuer exists. The yuan itself is not neutral. The proposal evaporates. Dollar hegemony survives the crisis it created.
Issuing country not neutral
2022 · Sanctions
$300 Billion Frozen — The Demand Becomes Urgent
Russia's $300 billion in foreign reserves are frozen overnight. Every finance ministry on earth watches. The message is clear: dollar reserves are not assets — they are leverage held by Washington. The demand for an alternative becomes existential. The mechanism still does not exist.
Demand urgent, mechanism missing
2024 · Purahu
The RTU: What Every Attempt Was Missing
Purahu builds the RTU — Real Trade Unit — from a proprietary sovereign model rooted in IMF, World Bank, BIS, and Penn World Tables data. No issuing nation. No political basket. A pure measurement of what each currency is actually worth against every other, priced on fundamentals that no army or sanction can erase.
Mathematics where politics failed

Global currency markets are entering
a period of structural change

Over the past decade the international economic environment has shifted from a relatively stable, integrated system toward a more fragmented and multi-polar landscape. Trade patterns, capital flows, and supply chains are adjusting in ways that are not always reflected in market exchange rates.

As a result, traditional FX pricing — while highly liquid and efficient in execution — can diverge from underlying economic conditions. This divergence is not constant, but it becomes more pronounced during periods of transition. RTU was built for this environment.

🌐
More Global Instability
As alliances shift and supply chains fragment, FX prices reflect capital flows more than economic fundamentals — creating measurable divergence RTU surfaces.
📊
More Pricing Inefficiency
In periods of structural change, market exchange rates and underlying economic conditions diverge more frequently. RTU identifies where — without political commentary.
🔬
More Demand for Better Signals
For institutions, traders, and analysts: clearer context for currency movements, structured signals beyond market price, and the ability to assess relative value.
RTU Does Not Replace FX
RTU provides an additional analytical lens — complementary to market pricing, not competitive with it. It tells you where market price and economic conditions are not fully aligned.

"In periods of structural change, market pricing and underlying economic conditions can diverge more frequently. RTU is designed to provide clarity in this environment."

Purahu RTU — Sovereign Intelligence Engine

𓂀

"She did not ask for permission to build what the world needed."

Hatshepsut ruled Egypt not by inheritance but by vision. She sent trade expeditions to Punt when the world said it couldn't be done. She built temples while advisors counseled caution. She understood that commerce, when properly priced, creates civilizations — not empires built on extraction.

The RTU carries that legacy forward. Not a weapon. A measuring rod. The kind Hatshepsut's merchants carried to Punt — so both sides of the trade knew exactly what they were exchanging.

Why every attempt failed
and why RTU succeeds

01
Politics Overrode Math
Bancor, SDRs, Zhou's proposal — each required a political consensus that never came. RTU is math. It does not require a G7 vote, an IMF board meeting, or Washington's blessing. The formula runs on public data. The output is the output.
02
No Data Infrastructure
In 1944, Keynes could not have built RTU — the data didn't exist. Today, IMF WEO, World Bank WDI, Penn World Tables, and BIS provide the 19 inputs for 133 nations updated annually. The data infrastructure took 80 years to build. We built the model on top of it.
03
Issuing Country Said No
Every proposal required a trusted issuer: gold, the US, the IMF, China. Each issuer had interests that corrupted the measurement. RTU has no issuer. It is a ratio — two RTU scores, one bilateral price. Neither country controls it. Neither can manipulate it.
04
Proposed Currencies ≠ Measurement
The yuan, the euro, gold, SDRs — these are currencies, not measurements. They carry the biases of their issuers. RTU is a measurement, like meters or Celsius. A thermometer does not have an agenda. Neither does RTU.

The world is ready

Finance ministers, traders, development economists, and sovereign wealth funds are all asking the same question: what is a fair price? Sign up for early access to RTU Intelligence Reports.

The FX market doesn't price
your economy. It prices
the dollar's interests.

"Every time you import goods, your government pays an invisible tax — not to your treasury, but to the architecture of dollar supremacy. It has no line item. It shows up in your inflation, your debt service, your trade deficit, and your children's wages."

— The FX Import Tax: How It Works

How the Hidden Import Tax Is Extracted

1

Your Currency Is Priced by Capital Markets, Not Your Economy

The exchange rate between your currency and the dollar is set primarily by foreign exchange traders in London, New York, and Singapore — not by the IMF, not by your central bank, and not by the goods you produce. These traders price currencies based on capital flows, interest rate differentials, and sentiment. Your inflation rate, your trade balance, your infrastructure — irrelevant to the daily fix.

2

The Dollar's Rate Is Structurally Inflated

The dollar benefits from what economists call "exorbitant privilege." Because reserves are held in dollars globally, demand for dollars is permanently elevated above what the US economy alone would justify. The US runs a 122% debt-to-GDP ratio, a persistent current account deficit, and a service-dependent economy where 40% of cognitive jobs face AI displacement — yet the dollar trades as though none of this exists.

3

Your Imports Are Invoiced in Overpriced Dollars

When Ethiopia buys petroleum, India buys semiconductors, or Nigeria buys machinery — the invoice arrives in dollars. At a dollar price structurally above its fundamental value. The buyer pays not the real exchange rate, but the real rate plus the privilege premium. This premium is not zero. For severe cases like Turkey and Nigeria, it exceeds 100%.

4

The Gap Becomes Inflation, Debt, and Stunted Wages

The import overcharge passes through the economy as higher consumer prices, higher production costs, and higher external debt service. Central banks raise rates to fight the inflation — which was caused by the dollar premium, not domestic excess. Rate hikes slow the economy. Real wages fall. The financial sector, which holds dollar assets, gains. The bottom 60% loses ground. The gap between financial wealth and wage income is not a failure of capitalism in the abstract — it has a mechanism. This is it.

5

RTU Makes the Tax Visible — and Correctable

RTU scores two economies on 19 fundamental factors. The bilateral ratio gives the fair trade price. The gap between this price and the FX rate is the import premium — quantified, published, and impossible to deny. Two countries can now negotiate, net, or route around it. Not by fighting the dollar. By measuring what their exchange should actually be.

Political sovereignty without
economic sovereignty
is a half-finished revolution

The decolonization wave of the 1950s–1970s transferred flags, constitutions, and parliaments — but left the price mechanism intact. Trade was still invoiced in sterling, then dollars. Debt was still borrowed in dollars. IMF conditions were still written to protect creditor interests. A nation can elect whoever it wishes. But if it cannot price its own exports, control its own import costs, or settle trade without first acquiring dollars — it remains economically colonized regardless of its constitution.

⚖️
The Colonial Price Mechanism Survived
Colonial extraction worked through price control — commodities bought cheap in local currency, sold expensive in sterling. Independence changed the flag. The price mechanism remained. Dollar invoicing of commodities, dollar-denominated debt, and dollar reserve requirements continued the extraction under a new name.
💥
Both Sides Now Pay the Price
The Western nations that designed this system are now experiencing its return effects. A dollar structurally overvalued hollows out US manufacturing. Dollar reserve privilege suppresses the discipline that would force fiscal correction. The debts accumulate. The political instability follows. The tables are not turning — they are leveling.
🔗
Sanctions as Economic Siege
The Iran conflict, the Russia freeze, the Venezuela blockade — each demonstrated that the dollar is a weapon, not a medium. Nations that held dollar reserves discovered those reserves could be frozen at will. Nations that traded in dollars found their trade routes could be severed by financial decree. No amount of military spending fixes a structural measurement problem. RTU does.

Force cannot fix what
fundamentals have already decided

Military blockades, tariff walls, and technology bans operate on the assumption that economic power can be contained by force. But economic power is rooted in fundamentals — resources, productivity, demographic depth, energy independence, reserve adequacy. China's RTU score reflects an economy with 6.83 FX rate while its fundamental value suggests 5.4. Japan, starved of energy independence and crushed by carry trades, scores 11 against a 157 yen — the market extracts 57% above fair value from every yen-denominated purchase. No blockade changes these numbers. No tariff fixes the measurement. RTU scores predict the direction of economic gravity regardless of political noise.

The new world order will not be determined by who has the most aircraft carriers. It will be determined by who has resources, who can price them fairly, and who can settle trade without needing a dollar they don't control. Purahu doesn't pick sides. It shows the math that every side must eventually face.

Finance wins. Labor loses.
The mechanism is the dollar.

The wealth gap between financial asset holders and wage earners is not an accident. It has a mechanism. When currencies are mispriced upward, import costs inflate. Central banks raise rates to fight the inflation. Rate hikes suppress wages and employment while they elevate the value of dollar-denominated financial assets. The top quintile holds financial assets. The bottom quintile holds wages. The structural dollar overvaluation is a continuous, invisible transfer from the bottom of the income distribution to the top — in every country that imports in dollars. RTU makes this transfer visible. Visibility is the first step to correction.

RTU Index · Lower score = stronger sovereign fundamentals · Scale reflects sovereign price pressure · Data: IMF WEO 2024 · World Bank · Penn World Tables

RTU evaluates sovereign currency strength through a proprietary multi-factor model built on macroeconomic fundamentals, real consumption behavior, and institutional quality indicators. The model integrates data from the IMF, World Bank, BIS, and Penn World Tables to produce a unified sovereign price index.

The specific factors, weights, transformation logic, and aggregation methodology are proprietary and constitute trade secrets of Purahu LLC. What is shown here is the high-level architecture — not the mechanics.
I
Price Stability
How effectively a sovereign manages inflation, monetary policy, and the integrity of its price signal. Unstable prices corrupt every measurement downstream — RTU accounts for this directly.
II
Sovereign Capacity
A nation's ability to absorb shocks, service obligations, and defend its currency. Includes debt structure, reserve adequacy, and external exposure. This is what FX markets routinely ignore until a crisis forces them to notice.
III
Real Consumption Basis
What people actually exchange within an economy — adjusted for purchasing power, remittance flows, and informal sector weight. FX rates reflect capital movement, not consumption reality. RTU prices the latter.
IV
External Balance & Structure
Trade position, external obligations, currency dependency, and energy exposure. A nation's structural relationship with the global economy — whether it earns or borrows its way through trade.
V
Institutional & Data Integrity
Governance quality, rule of law, political stability, and the reliability of the sovereign's own data. A score built on bad data is worthless. RTU prices data quality as a first-order input, not a footnote.

RTU is not a credit rating. It is not a country risk score. It is not a political index. It is a sovereign price measurement — a metric that answers one question: at what price should two economies actually exchange with each other, given their real fundamentals? That question has never had a neutral answer. RTU provides one.

RTU draws from global institutional datasets updated annually. The selection, normalization, and integration of these sources is proprietary. The underlying raw data is public — how it becomes a sovereign price is not.

AI will take the cognitive jobs.
The new world runs on resources.
RTU measures both.

Three transitions are happening simultaneously. Dollar unipolarity is ending. AI is automating cognitive work. Open data infrastructure now makes a sovereign measurement possible. Purahu sits at the intersection of all three.

40%

RTU factors that measure permanent sovereign endowments — resources, governance, reserves — that AI cannot automate or replicate
$0
is what AI adds to a country's mineral reserves, agricultural land, coastal access, or demographic base — RTU prices what remains real
🌐
Dollar Unipolarity Ending
The $300B Russian freeze was the inflection point. Nations that held dollar reserves discovered they were holding conditional assets. The BRICS payment corridors, PAPSS in Africa, CIPS in Asia — these are not threats to the dollar. They are the market's response to the absence of a neutral measure. RTU is that measure.
🤖
AI Automates Cognitive Labor
AI will not replace the farmer, the miner, the builder, or the nurse. It will replace the analyst, the paralegal, the underwriter, the call center agent, and the mid-level manager. The countries that believed their service economies were safely post-industrial will discover their labor pricing assumptions were wrong. RTU's proprietary model factors include productivity, governance, and energy — none of which AI replaces.
📡
Open Data Infrastructure Arrives
IMF WEO, World Bank WDI, Penn World Tables, BIS — all of these datasets, which took 50 years to build, are now publicly accessible and machine-readable. The technical barrier that prevented Keynes's Bancor from existing in 1944 is gone. RTU was not possible in 1971. It is necessary in 2024.

As AI advances,
RTU becomes more accurate

Here is the counterintuitive truth: the more AI disrupts labor markets, the more important sovereign fundamentals become. FX rates will break down as their primary anchor — labor cost differentials — gets automated away. RTU scores sovereign endowments that are not labor-dependent: reserves, debt ratios, energy access, governance quality, trade structure. These become the new basis of economic measurement in an AI world.

For American workers: wages have stagnated while financial asset prices have soared. The mechanism is the same dollar structure that extracts from Nigeria and Ethiopia. When AI displaces the cognitive middle class, the same mechanism that suppressed Global South wages for 80 years will arrive on Main Street, USA. RTU identifies this dynamic — and provides the correction mechanism.

Hands will not be replaced. Desks will.

The post-industrial service economy assumed that knowledge work was the highest-value, most defensible position in the global division of labor. AI invalidates this assumption. What remains irreplaceable is physical: agricultural yield, mineral extraction, coastal trade routes, hydroelectric capacity, skilled manual trades. RTU's energy diversity factor, trade balance factor, and productivity factor already measure these — precisely because they were always the real foundation of sovereign economic capacity. The AI age doesn't make RTU obsolete. It makes RTU essential.
