Cuba is in Trouble
1. Introduction: The Ontological Reassessment of the Cuban Peso
The structural unraveling of the Cuban economy between the years 2020 and 2026 provides a profound, if tragic, empirical testing ground for contemporary macroeconomic and monetary theories. Traditional functionalist definitions of money—which define a currency merely by its symptoms as a medium of exchange, a unit of account, and a store of value—fail to capture the ontological reality of the hyperinflationary spiral currently devastating the Cuban peso (CUP). To thoroughly diagnose the etiology of Cuba’s economic collapse, it is analytically necessary to deploy Capacity-Based Monetary Theory (CBMT). This theoretical framework posits that money is not an arbitrary fiat token sustained merely by state decree, but rather a circulating promissory note—a floating-price claim on the expected future productive capacity, or the "Expected Future Impact," of the society that issues it.
Under the rigorous framework of CBMT, the liability of a sovereign's money supply on the balance sheet of a civilization must be balanced by the underlying asset of the nation's productive capacity. When an economic agent holds the Cuban peso, they are essentially acquiring a call option on the aggregate future labor, the technological efficiency, and the institutional stability of the Cuban state. Therefore, the purchasing power of the currency operates as a real-time pricing index of the economy's production function and the viability of its underlying social contract. The hyperinflation experienced in Cuba over the last half-decade—reaching an estimated 500% in 2021 and 200% in 2022, alongside a precipitous devaluation of the peso in the informal market—cannot be understood merely as a standard monetary phenomenon involving the over-issuance of the broad money supply (M2). Rather, it reflects the simultaneous and catastrophic degradation of Cuba's physical capital, the rapid and unrecoverable depletion of its human capital, and the terminal failure of its institutional frameworks to realize productive value.
This comprehensive research report provides an exhaustive analysis of the Cuban economic crisis through the specific analytical lens of Capacity-Based Monetary Theory. It integrates the augmented Mankiw-Romer-Weil (MRW) production framework to evaluate physical and human capital dynamics, deploys Douglass North’s institutional jurisprudence to measure transaction costs, and utilizes stochastic regime-switching models—specifically the Hamilton Filter—to formally map the collapse of Cuba’s macroeconomic collateral. By meticulously dissecting the failure of the 2021 Tarea Ordenamiento (Monetary Reordering Task) and the subsequent monetization of highly unsustainable fiscal deficits, this analysis demonstrates how deeply ingrained structural inefficiencies have effectively liquidated the asset base backing the Cuban currency. The ultimate result is an infinite discount rate on the nation's expected future impact, driving the fundamental value of the fiat liability toward zero.
2. Theoretical Foundations: Capacity-Based Monetary Theory (CBMT)
To rigorously operationalize the valuation of the Cuban peso and understand the mechanics of its hyperinflationary demise, macroeconomic analysis must move beyond the traditional Fisherian equation of exchange ($MV=PQ$). While monetarist frameworks correctly identify the relationship between money supply and price levels, they often obscure the underlying physical and institutional collateral that gives a fiat currency its purchasing power. Capacity-Based Monetary Theory corrects this by formalizing the "hardware and software" of the economy into a unified valuation model. CBMT asserts that money is a direct derivative of future real output ($Y$), which serves as the ultimate collateral for the currency.
If a society's money supply remains completely constant while its capacity to produce tangible goods, services, and innovations expands, the purchasing power of that money increases, resulting in deflation. Conversely, if the productive capacity degrades while the claim structure (the money supply) remains fixed or expands, the value of the claim rapidly dilutes, resulting in inflation. In the case of Cuba, the economy is suffering from a catastrophic simultaneous occurrence: the rapid expansion of the claim structure through central bank deficit monetization, paired with the complete collapse of the underlying capacity engine.
The CBMT framework requires the integration of three distinct theoretical pillars to calculate the fundamental value of a currency. First, the "hardware" of the economy must be modeled using advanced production theory, specifically the Augmented Solow-Swan model as specified by Mankiw, Romer, and Weil, which separates raw labor from human capital. Second, the "software" of the economy must be quantified through institutional economics, utilizing the concepts of transaction costs and the Hobbesian trap to derive an Institutional Realization Rate. Third, the pricing of these factors in a non-deterministic, highly volatile world must be calculated using regime-switching algorithms to account for the sudden collapse of social contracts. When synthesized, these pillars reveal that the price of the Cuban peso is not an anomaly, but a highly accurate, mathematically sound reflection of a nation that has lost the capacity to project value into the future.
3. Modeling Cuba's Productive Capacity: The MRW Framework
The starting point for quantifying the macroeconomic collateral of the Cuban state is the augmented Solow-Swan growth model, specifically the Mankiw, Romer, and Weil (1992) specification. The standard neoclassical Solow model is entirely insufficient for analyzing modern economies—and particularly the Cuban economy—because it treats human capital merely as a fungible component of raw labor. To accurately map the true collateral of the Cuban peso, the MRW specification is required, as it treats Human Capital ($H$) as an independent factor of production with its own unique accumulation and depreciation dynamics.
The rigorous production function for a nation's theoretical capacity, or "Impact," is mathematically defined within the CBMT framework as:
$$Y_t = A_t \cdot K_t^\alpha \cdot H_t^\beta \cdot L_t^{1-\alpha-\beta}$$
Within this equation, $Y_t$ represents the total tangible goods, services, and innovations produced, serving as the underlying collateral. The variable $A_t$ represents labor-augmenting technology, capturing the overall efficiency and total factor productivity (TFP) of the civilization. $K_t$ is the accumulated stock of physical capital, including infrastructure, machinery, and industrial plants. $H_t$ is the stock of human capital, reflecting the advanced skills, health, and specialized education of the populace. Finally, $L_t$ is the aggregate raw labor force. The exponents $\alpha$ and $\beta$ represent the elasticities of output with respect to physical and human capital, respectively, and their sum is constrained to imply diminishing returns to capital accumulation.
In the context of currency valuation under CBMT, the strength of the Cuban peso relies heavily on the state's investment rate in physical capital ($s_k$) and human capital ($s_h$) being sufficient to outpace the natural depreciation of these assets ($\delta$) and the dynamics of population growth ($n$). As the subsequent sections will demonstrate through empirical data, Cuba's fundamental crisis stems from a systemic inability to maintain the investment rate in physical capital, causing a severe contraction in the stock of $K_t$, while simultaneously suffering massive, exogenous shocks to both its human capital ($H_t$) and its raw labor force ($L_t$) via historic waves of emigration.
4. The Collapse of the Labor Force ($L$) and the Demographic Void
The raw labor input ($L$) of the Cuban economy is experiencing a rapid, unprecedented, and structurally irreversible decline. During the mid-to-late 20th century, economic growth throughout Latin America and the Caribbean was largely driven by expanding labor forces, allowing nations to capitalize on a demographic dividend. However, Cuba today exhibits the characteristics of an advanced, terminal demographic transition. This transition is characterized by extraordinarily low fertility rates, low mortality levels, and high life expectancy, leading to an inverted population pyramid.
The empirical data highlights the severity of this demographic void. Between the years 2000 and 2024, the total population of Cuba fell from 11,109,109 to 10,979,783, representing an initial 1.2% decrease. However, this trend has recently accelerated to a catastrophic degree; by the end of 2024 alone, the nation recorded an annualized population decrease of 3%. The internal structure of this shrinking population is heavily skewed toward the elderly. In 2024, individuals over 65 years of age accounted for 16.6% of the total population, which is a massive 6.8 percentage point increase compared to the year 2000. Consequently, the Cuban economy is burdened with an exceptionally high dependency ratio, calculated at 46.8 passive individuals for every 100 potentially active individuals. This severely limits the aggregate productive capacity of the nation, as a shrinking pool of active workers must generate the surplus required to sustain a growing demographic of retirees.
Furthermore, the raw labor pool is not merely aging; it is being actively decimated by mass emigration. In the year 2022 alone, Cuba witnessed an unprecedented wave of emigration, with over 300,000 Cubans undertaking the perilous journey to the United States, while tens of thousands more sought refuge in Europe and other Latin American nations. This mass exodus was further fueled by temporary immigration policies, such as the ability to cross into the United States via Mexico, which acted as a safety valve for intense domestic political and economic frustration. Within the CBMT and MRW frameworks, this exodus acts as a severe negative shock to the $L_t$ variable. The nation is actively bleeding the exact demographic required to staff its industries, maintain its infrastructure, and produce the tangible goods necessary to balance the central bank's expanding monetary liabilities. The loss of this demographic directly reduces the aggregate capacity of the economy, ensuring that the expected future impact of the Cuban state continues to contract.
5. The Paradox of Cuban Human Capital ($H$)
While the contraction of raw labor is damaging, the dynamics of Cuba's Human Capital ($H$) present a unique macroeconomic paradox that CBMT is perfectly calibrated to explain. Gary Becker’s foundational theories on the allocation of time suggest that labor is not a fungible, homogeneous commodity, but rather a specialized form of capital that is accumulated through heavy societal and individual investment. Historically, the central pillar of the Cuban economic model was its profound, state-sponsored investment in human capital. The nation boasts a highly educated and remarkably healthy populace, with a literacy rate that has been maintained at 99.9% across both genders. Furthermore, the life expectancy at birth in 2024 was recorded at 78.3 years, outperforming the averages of the broader Region of the Americas and remaining significantly higher than the 75.9 years recorded in 2000.
The World Bank’s Human Capital Index (HCI) further quantifies this anomaly. The HCI indicates that a child born in Cuba just prior to the pandemic would be expected to be 73% as productive in adulthood as they could theoretically be with complete education and full health. This metric is substantially higher than the 56% average for the Latin America and Caribbean region, and outpaces the average for Upper-Middle-Income countries globally. The advanced nature of the labor force is also reflected in the data; at its peak in the previous decade, over 81% of the total working-age population possessed advanced education, including tertiary and doctoral degrees, while the intermediate education rate stood at over 63%.
Under a standard, un-augmented neoclassical growth model, this massive accumulated stock of human capital should yield extraordinary economic output and robust GDP growth. However, Cuba represents a unique and persistent paradox in the academic literature: it features immense equity and world-class human capital, yet delivers paltry, stagnating economic growth. In the Capacity-Based Monetary Theory model, human capital ($\beta$) does not exist in a vacuum; it requires the concurrent existence of physical capital ($\alpha$) and a high institutional realization rate ($\theta$) to become productive. A society of highly trained engineers and specialized doctors cannot generate real economic output without modern technology, functional machinery, reliable energy grids, and the market incentives required to allocate their time efficiently.
Tragically, this immense stock of human capital is currently undergoing rapid liquidation. The recent waves of emigration are not randomly distributed across the population; the individuals fleeing the island are disproportionately young, highly educated professionals seeking environments where their human capital can generate realized returns. This brain drain is hollowing out the most critical sectors of the Cuban state. According to official figures, the mass exodus has resulted in an estimated 40,000 vacancies in the healthcare sector alone. Historically, the Cuban government leveraged its medical industry as a primary source of foreign exchange, exporting health care professionals to countries with doctor shortages in exchange for commercial services and energy. The loss of these professionals represents a catastrophic depletion of the state’s premium collateral. The nation is actively losing the highly skilled subset of the population required to generate the complex, high-value output needed to defend the currency, permanently lowering the long-term ceiling of the nation's expected future impact.
6. The Eradication of Physical Capital ($K$) and Efficiency ($A$)
A currency backed by a highly educated population must also be backed by the physical infrastructure required to amplify that labor into tangible output. Decades of chronic underinvestment, stemming initially from the collapse of the Soviet Union (which abruptly ended heavy subsidies and technical support) and compounded by deeply flawed, highly centralized macroeconomic planning, have left Cuba severely deficient in physical capital accumulation.
To maintain a physical capital stock ($K_t$), a nation's investment rate ($s_k$) must continuously exceed the rate of capital depreciation ($\delta$). In Cuba, this fundamental mathematical requirement has not been met for years. The rate of gross fixed capital formation (GFCF)—the standard proxy for investment in physical capital—averaged a mere 13.9% of GDP between the years 2002 and 2022, reaching 15% in 2022. This level of investment is vastly insufficient to cover the depreciation of aging Soviet-era infrastructure in a tropical climate. More alarmingly, the investment growth trend has turned steeply negative since 2019, registering a contraction of -6% in 2022. This lack of domestic reinvestment is empirically reflected in the shrinking share of capital goods in Cuba's total imports, which dropped from an already low 12% in 2013 to just 9% in 2021.
The empirical manifestations of this capital degradation are systemic, highly visible, and devastating across all primary sectors of the economy:
The Energy Infrastructure Collapse: The national energy grid relies entirely on highly obsolete, rapidly deteriorating thermal power plants. The long-term lack of investment, combined with a severe shortage of the foreign currency required to purchase imported fuel, has led to a complete inability to maintain generation capacity. This results in frequent, catastrophic failures of the national power grid and prolonged blackouts that paralyze all other productive and domestic activities, acting as an absolute bottleneck on economic output.
The Destruction of the Industrial Base: The sugar industry, which was historically the backbone of the Cuban economy and its primary connection to global trade, has seen its physical plant entirely collapse. The number of operational sugar mills plummeted from 156 in 1990 to just 44 in 2021. Due to obsolete machinery and a lack of spare parts, less than half of these remaining mills were able to participate in the 2023 harvest, rendering the industry's derivatives production unsustainable.
Construction and Civil Infrastructure: The capacity to rebuild is also degrading. In 2024, Cuba produced only about 50% of the gray cement output it managed in the previous year, severely limiting any capacity for infrastructure regeneration. The nation's physical infrastructure, particularly its road networks, has deteriorated to unprecedented levels, leaving critical transportation routes impassable and further increasing the logistical friction of internal trade.
Simultaneously, the technology and efficiency multiplier ($A_t$) within the MRW equation is stagnating. Total factor productivity (TFP), which measures how efficiently an economy turns its capital and labor inputs into outputs, has suffered from eight consecutive years of steep decline. This persistent degradation has effectively wiped out all the modest productivity gains the nation achieved during the early 2000s. The combination of bureaucratic inefficiencies, state-mandated control over distribution logistics, and deep technological obsolescence has created a persistent production gap. By the end of 2024, the economy operated with an 11% deficit compared to pre-pandemic (2019) levels, leaving basic market demand chronically undersupplied by an estimated 30% to 50%. In CBMT terms, the degradation of $A_t$ depresses the multiplier for all other inputs, suppressing total output ($Y$) and shrinking the asset base that backs the currency.
| MRW Production Variable | Cuban Economic Status & Empirical Data (2020-2026) | Impact on CBMT Currency Valuation ($M_v$) |
|---|---|---|
| Labor ($L$) | 3% annualized population decline (2024); mass exodus of over 300,000 citizens in 2022. | Severely reduces the aggregate capacity pool and ensures high dependency ratios. |
| Human Capital ($H$) | Historically elite (99.9% literacy), but rapidly depleting via the emigration of professionals (e.g., 40,000 healthcare vacancies). | Rapid liquidation of the state's premium collateral; lowers the long-term technological ceiling. |
| Physical Capital ($K$) | Negative capital formation rate (-6% in 2022); obsolete, failing energy grid and decimated industrial infrastructure. | Massive increases in depreciation ($\delta$); limits the productivity of the remaining labor force. |
| Efficiency/TFP ($A$) | 8 consecutive years of TFP loss; severe logistical bottlenecks and technological obsolescence. | Depresses the efficiency multiplier, suppressing total output ($Y$) regardless of labor input. |
7. Institutional Jurisprudence and the Realization Rate ($\theta$)
While the deep contraction of the MRW variables explains the loss of theoretical capacity, the stark discrepancy between Cuba's historical human capital investments and its dismal economic reality highlights the absolute centrality of the Institutional Realization Rate ($\theta$) in the Capacity-Based Monetary Theory equation. Theoretical production capacity is economically meaningless if the fruits of labor cannot be secured, traded, and projected into the future. When institutions fail to protect property and enforce contracts, transaction costs approach infinity, and the expected future impact becomes entirely unrealizable.
7.1 Transaction Costs and the Centralized State Apparatus
The institutional frameworks of Douglass North postulate that economies thrive when humanly devised constraints—such as constitutions, laws, and property rights—are designed to encourage market integration, protect investments, and reduce uncertainty in exchange. In high-trust societies with robust rule of law, the realization rate ($\theta$) approaches 1, meaning theoretical capacity is fully realized as economic output. Conversely, in economies dominated by political elites with stakes in preserving the status quo, institutions are often designed to extract rents, resulting in astronomical transaction costs that stifle all productive methods.
In Cuba, the state apparatus controls the vast majority of the economy, and the institutional environment is characterized by infinite transaction costs. Private property rights are fundamentally weak, precarious, and explicitly subordinate to the state. The constitutional recognition of private property only occurred recently in 2019, and the legislative framework to legitimize small and medium-sized enterprises (MSMEs) was not formally passed until 2021. The Bertelsmann Transformation Index (BTI) categorizes property rights in Cuba as exceptionally weak, assigning a dismal rating of 2.5 out of 10. The state retains the arbitrary, unchallengeable power to revoke self-employment licenses, expropriate business assets, and dictate forced collection quotas for agricultural production. This oppressive environment ensures that $\theta$ remains severely depressed. Potential investors—both domestic entrepreneurs and foreign capital—must price in the near-certainty of state interference and regulatory strangulation, effectively raising the discount rate on any long-term investment to prohibitive, uneconomic levels.
7.2 The Frictional Costs of the Dual Exchange Rate System
Prior to its chaotic dissolution in 2021, Cuba operated a deeply distortionary and complex dual-currency system involving the Cuban Peso (CUP) and the Convertible Peso (CUC). The CUC was artificially pegged at a 1:1 ratio to the US dollar for state enterprises and the international sector, while the general public utilized the standard CUP at a rate of 24:1.
This dual-rate regime was a textbook generator of immense institutional opacity and systemic transaction costs. The unprecedented 2,300% spread between the official and parallel exchange rates created a massive quasi-fiscal mechanism that implicitly subsidized highly inefficient state-owned enterprises (SOEs) by granting them access to cheap imported goods, while simultaneously heavily taxing any exporting or import-substituting entities through forced surrender requirements. This architecture segmented the entire economy into "winning" and "losing" sectors based entirely on political proximity and state favor, rather than productive efficiency or market demand. It fostered pervasive, socially destructive rent-seeking behaviors and endemic corruption throughout the state administration. Within the CBMT model, this dual-rate system served as an explicit friction parameter, aggressively lowering $\theta$ by persistently misallocating both physical and human capital away from their highest-impact, most efficient uses.
7.3 Exogenous Shocks and The Hobbesian Trap
The CBMT model suggests that the existence of money requires a stable "Leviathan"—a functional state authority capable of lowering transaction costs and guaranteeing the passage of time necessary for citizens to redeem their claims on the future. The Cuban Leviathan is currently fracturing under the compounded weight of interconnected exogenous and endogenous shocks.
Externally, the island has faced severe economic asphyxiation. The gradual loss of cheap energy subsidies from its strategic ally Venezuela (beginning in 2019), the absolute devastation of the critical international tourism sector during the COVID-19 pandemic, and the severe tightening of the U.S. embargo under the Trump administration (which has largely been maintained by the Biden administration) have choked off the nation's primary sources of foreign exchange. Furthermore, the designation of Cuba as a State Sponsor of Terrorism has effectively severed the island from standard global banking and financial networks, drastically raising the transaction costs and risk premiums associated with any international trade.
Internally, this economic suffocation triggered the unprecedented nationwide protests of July 11, 2021. The state’s response to these demonstrations—swift, brutal suppression, and the meting out of disproportionately long jail sentences to ordinary protesters—fundamentally shattered the government's promise of a "socialist rule of law". When a society transitions away from institutional stability and toward a Hobbesian condition of widespread public dissent countered by state violence, economic agents lose all faith that the future will resemble the past. Following these events, the value of $\theta$ in Cuba plummeted. The resulting societal resignation and despair are the primary behavioral drivers behind the mass exodus; citizens are rationally choosing to physically migrate to institutional environments (such as the United States) that possess a higher $\theta$, where their accumulated human capital ($H$) can generate realized economic returns without the threat of expropriation.
8. Regime-Switching Models and the 2021 Hyperinflationary Shock
The Cuban hyperinflationary crisis of 2021-2026 provides a flawless, textbook application for the integration of regime-switching models within Capacity-Based Monetary Theory. Hyperinflation is rarely driven by a slow, linear expansion of the money supply; it is almost always catalyzed by a sudden, discrete regime shift in the public's perception of the state's institutional viability and its future capacity to produce value. To accurately price the Cuban peso, one must apply the Hamilton Filter, a recursive algorithm that estimates the probability that the economy has transitioned into an unobserved collapse state ($S_t = Collapse$).
8.1 The Tarea Ordenamiento as a Disastrous Regime Shift
In January 2021, the Cuban government aggressively implemented the Tarea Ordenamiento (Economic Reordering Task). This sweeping macroeconomic reform was intended to unify the dual currency system, establish a single fixed exchange rate of 24 CUP to the USD, adjust domestic prices, and scale back universal state subsidies in favor of targeted social assistance.
While the unification of the exchange rates was theoretically necessary to remove the profound institutional distortions outlined previously, the execution occurred at the worst possible macroeconomic moment in modern Cuban history. The economy was already reeling from the pandemic-induced collapse in tourism and a severe, structural lack of foreign exchange reserves. Instead of boosting productivity and clarifying market signals, the reform acted as an immediate, catastrophic supply shock. Because the state lacked the requisite foreign currency reserves to defend the new 24:1 peg in the open market, the official exchange mechanisms immediately froze, and liquidity vanished.
Applying the Hamilton Filter to this historical event, the chaotic implementation of the Tarea Ordenamiento signaled to the market a definitive, irreversible shift from a "Stagnant but Stable" regime to a "Collapse" regime ($S_t = Collapse$). The sudden realization that the state apparatus could no longer guarantee the value of the CUP triggered an immediate, explosive repricing of the currency's fundamental value by the populace. Official state inflation closed 2021 at an estimated 500%, followed by an additional 200% inflation in 2022, entirely destroying the purchasing power of the populace.
8.2 The Monetization of the Fiscal Deficit
As physical output ($Y$) collapsed across all sectors, the state’s tax revenues plummeted concurrently. In a desperate attempt to mitigate the intense social and political fallout of the Tarea Ordenamiento and the accompanying inflation, the government dramatically increased state salaries and pensions. This sequence of events created an enormous, unbridgeable chasm in the national budget.
While Cuba has historically run a structural budget deficit averaging 6.3% of GDP since 2012, the current crisis caused this deficit to balloon out of control, reaching an astonishing 12.3% of GDP in 2024. Furthermore, the state budget for 2025 anticipates a continued fiscal imbalance exceeding 10% of GDP. Because Cuba is entirely locked out of international capital markets due to strict US financial sanctions and a long history of defaults, it cannot issue sovereign debt bonds to foreign buyers to finance this gap. Consequently, the state has been forced to rely on the direct, aggressive monetization of the deficit through the central bank. The state is printing billions of CUP without any corresponding backing in productive assets, foreign exchange reserves, or physical output.
In the formal mathematical framework of CBMT:
$$M_v = \frac{\theta(Y_t)}{M_2} - \pi(S_t = Collapse)$$
The denominator of this equation—the M2 money supply—is expanding at an exponential rate purely to cover administrative state expenditures, while the numerator—the realizable productive capacity of the island—is rapidly shrinking due to demographic collapse, failing physical infrastructure, and immense institutional friction. The mathematical inevitability of this divergence is hyperinflation. Every peso-based wage, savings account, and state pension is being eroded almost overnight, as the state effectively shifts the cost of its economic adjustment onto the most vulnerable sectors of society.
| Macroeconomic Indicator | 2021 | 2022 | 2023 | 2024 |
|---|---|---|---|---|
| Real GDP Growth | 1.3% (Slight Rebound) | 1.5% | -1.3% | -2.0% (Estimated Contraction) |
| Fiscal Deficit (% of GDP) | ~11.6% | ~9.5% | ~8.0% | 12.3% |
| Official Inflation Rate | ~500% | ~200% | 31% | 25% (Real street inflation vastly higher) |
| Informal Exchange Rate (CUP/USD) | ~70 | ~170 | ~265 | 350 - 400+ |

9. Signaling Theory, Dollarization, and the Informal Exchange Oracle
To survive in a hyperinflationary environment where the domestic currency no longer functions as a reliable store of value or a medium of exchange, the Cuban populace and the emerging private sector have been forced to rapidly adapt. The Capacity-Based Monetary Theory integrates Amotz Zahavi’s Handicap Principle and Michael Spence’s signaling mathematics to explain how market participants navigate these high-friction, low-trust environments by utilizing alternative currencies to prove their economic capacity.
9.1 Assortative Matching and the Proof of Surplus Capacity
In the CBMT framework, the expenditure or possession of difficult-to-acquire capital serves as a reliable, hard-to-fake signal of an economic agent's surplus capacity and their potential for future impact. In modern Cuba, this vital economic signaling mechanism has transitioned entirely away from the collapsing national currency toward hard foreign currency (primarily USD and Euros) and the digital Moneda Libremente Convertible (MLC).
The government’s introduction of MLC stores—which sell essential food items, home appliances, and basic hardware exclusively in foreign currency via specialized debit cards—was a desperate attempt by the state to capture circulating hard currency from the populace. However, this policy birthed a deeply segmented, heavily dollarized economy. Access to USD or MLC serves as a hard "Handicap Principle" filter. Because the state does not pay its employees in USD (the average monthly state salary of roughly 6,500 CUP equates to a mere $16-$17 USD on the informal market), holding foreign currency definitively proves that an individual has access to external remittance networks or successfully operates within the lucrative, dollarized private and tourism sectors.
By operating exclusively in foreign currencies, private businesses and successful individuals engage in "Assortative Mating" within the economic sphere, a dynamic perfectly modeled by Michael Kremer's O-Ring Theory of Economic Development. High-capacity individuals and businesses choose to transact only with other high-capacity entities using USD or MLC. They effectively bypass the state’s collapsing CUP-based production chain entirely, because accepting CUP introduces the fatal risk of sudden, severe devaluation—akin to a low-skill worker making a mistake that destroys the value of an entire complex production chain.
9.2 The Private Sector and the AI Pricing Oracle
Despite facing immense regulatory hurdles and state suspicion, non-state Micro, Small, and Medium Enterprises (MSMEs) have become the primary engine of basic survival in Cuba. Remarkably, the private sector met an estimated 55% of total retail demand in 2024, a significant increase from 44% in 2023. Because the formal state banking system suffers from severe illiquidity and a total lack of hard currency, these private actors are forced into the informal market to obtain the foreign exchange necessary to import goods and maintain their operations.
The private sector is effectively attempting to reconstruct the Institutional Realization Rate ($\theta$) from the ground up, relying on localized, high-trust networks and direct foreign supply chains to bypass the macro-level Hobbesian friction of the central state apparatus. However, with the official exchange rate (which the government adjusted from 24:1 to 120:1 for individuals) acting as a rigid, artificial construct with absolutely no underlying liquidity, the true valuation of the state's future capacity must be discovered elsewhere.
This price discovery occurs on the informal market, tracked by independent, AI-driven platforms such as El Toque. By scraping data from social media and informal trading groups, El Toque provides the only reliable volatility index of the Cuban peso. In late 2025, this informal rate breached the devastating threshold of 400 CUP/USD, accelerating rapidly toward 450 and 500 CUP/USD. This massive divergence between the official and informal rates measures the precise magnitude of the institutional fiction perpetuated by the state. The informal rate serves as a real-time, empirical manifestation of the Hamilton Filter update step: every time the national power grid fails, every time the government monetizes a new fiscal deficit, and every time thousands of highly educated citizens emigrate, the collective market algorithmically downgrades the probability of future impact, spiking the discount rate, and pushing the CUP/USD ratio ever higher.
10. Conclusion: The Terminal Valuation of the Cuban Economy
The Cuban economic crisis provides a stark, tragic, and mathematically precise validation of Capacity-Based Monetary Theory. Money is unequivocally a claim on the future productive capacity of a civilization. For over six decades, the Cuban state invested heavily in the Human Capital ($H$) of its population, creating a theoretical capacity for immense economic output that was the envy of the developing world. However, by simultaneously imposing an institutional architecture that maximized transaction costs, destroyed market price signaling, and chronically underinvested in physical capital, the state systematically pushed the Institutional Realization Rate ($\theta$) toward absolute zero.
The Tarea Ordenamiento in 2021 was merely the structural catalyst that forced the market to finally and accurately price these underlying realities. Deprived of essential foreign subsidies, isolated from global financial networks, and facing a terminal demographic collapse, the state resorted to printing unbacked fiat currency merely to sustain its own administrative existence.
Applying the comprehensive CBMT formulation to the Cuban reality yields a grim calculus. The labor force and human capital are in a state of active, physical depletion due to a massive, structural brain drain. Physical capital is deteriorating exponentially, manifesting as a crumbling energy grid and a collapsed industrial base. The institutional friction remains insurmountable due to a monolithic state apparatus that restricts private enterprise and relies on the suppression of dissent. Consequently, the discount rate on the future has spiked to hyperinflationary levels because the market correctly interprets state actions as a permanent collapse of the fiscal-monetary social contract.
When the efficiency, physical capital, human capital, raw labor, and institutional integrity of a nation are all trending steeply downward, while the supply of money expands infinitely to cover non-productive government deficits, the value of the currency approaches zero asymptotically. The hyperinflation tracked mercilessly by the informal exchange rate is not an anomaly; it is the market's declaration that it no longer expects the Cuban state to possess the capacity to redeem its fiat liabilities. Until comprehensive structural reforms restore the integrity of property rights, incentivize the accumulation of physical capital, and halt the desperate exodus of human capital, the Cuban peso will remain a liability without collateral, destined for continuous devaluation in the shadow of a stalled economic engine.
