Part I: Introduction and Macroeconomic Context

1.1 The Duality of Jamaican Economic Performance

The contemporary Jamaican economy presents a striking paradox to the analytical observer, a duality characterized by robust nominal stability indicators on one hand and persistent structural vulnerabilities on the other. This dichotomy is most vividly illustrated by the recent announcement from the Bank of Jamaica (BOJ) regarding the nation’s Net International Reserves (NIR). As of December 2025, Jamaica’s international reserves have reached a historic milestone of US$6.3 billion. This accumulation, representing approximately 151% of the Assessing Reserve Adequacy (ARA) metric considered sufficient for external stability, has been heralded by state authorities as a definitive triumph of fiscal discipline and astute monetary management. Ideally, such a formidable buffer would signal an economy that has insulated itself against external shocks, secured its currency, and paved the way for sustainable growth.

However, a critical examination of this achievement, juxtaposed against the structural realities of the Jamaican market, reveals a more complex and potentially precarious narrative. The critique posits that the pursuit of these high-level aggregates—specifically the simultaneous maintenance of record reserves, an inflation-targeting regime, and open capital markets—may be masking, or even exacerbating, deep-seated financial risks. This tension is encapsulated in the critical assertion that Jamaica is “attempting the ‘Holy Trinity’ while committing the ‘Original Sin’”. This theoretical framing suggests that the macroeconomic architecture is built upon conflicting policy objectives that, when interacting with a debt stock heavily denominated in foreign currency, expose the fiscal accounts to debilitating volatility.

To understand the gravity of this critique, one must look beyond the headline figure of US$6.3 billion. While the reserves provide more than 25 weeks of import cover—far exceeding the international benchmark of 12 weeks—the composition and cost of these reserves warrant scrutiny. A significant portion of these inflows is not derived from organic trade surpluses or productivity gains in the real sector. Instead, Direct Remittance Investments (DRI) from the Jamaican Diaspora have emerged as the single largest contributor of inflows to the NIR, significantly outpacing Foreign Direct Investment. These flows are further buoyed by “disaster risk financing, multilateral funding, and grant flows,” including proceeds from the Caribbean Catastrophe Risk Insurance Facility (CCRIF) and Catastrophe Bonds. This implies that the liquidity buffer is, to a non-trivial extent, a function of debt, diaspora support, and contingent liability management rather than a reflection of export competitiveness or industrial might.

Furthermore, this accumulation occurs against a backdrop of contraction in the real economy. The Planning Institute of Jamaica (PIOJ) has estimated a contraction in economic activity ranging from 1.0% to 3.0% for the December 2025 quarter, driven by the adverse effects of Hurricane Melissa and disruptions in the agricultural sector. This divergence—record financial assets held by the central bank versus shrinking output in the productive sectors—lies at the heart of the “Deep Financial Risks” critique. It raises fundamental questions about the opportunity costs of sterilization, the allocation of national capital, and the sustainability of a debt management strategy that remains vulnerable to the “Original Sin” of foreign currency dependence.

1.2 Theoretical Framework: The Intersection of Two Hypotheses

The analytical core of this report rests on the interaction between two seminal concepts in international macroeconomics: the “Impossible Trinity” (or Mundell-Fleming Trilemma) and the hypothesis of “Original Sin.”

The Impossible Trinity postulates that an economy cannot simultaneously achieve a fixed exchange rate, free capital movement, and an independent monetary policy. A nation must choose two of these three objectives, as the third becomes mathematically impossible to sustain. For example, if a country maintains free capital flows and sets its own interest rates (independent monetary policy) to combat domestic inflation, arbitrage opportunities will induce capital flows that pressure the exchange rate, making a fixed rate unsustainable without massive reserve depletion or capital controls.

Original Sin, a term coined by economists Barry Eichengreen and Ricardo Hausmann, refers to the structural inability of a developing country to borrow abroad in its own currency. Consequently, the nation accumulates external debt denominated in foreign currencies (typically the US Dollar). This creates a currency mismatch on the national balance sheet: the government’s assets and revenue streams are in local currency (Jamaican Dollars), while its liabilities are in foreign currency.

The confluence of these two phenomena in Jamaica creates a unique policy trap. The government has formally adopted Inflation Targeting (IT) and liberalized its capital account, which, under the Trinity framework, necessitates a floating exchange rate. However, because of “Original Sin”—where nearly 60% of the central government’s debt is denominated in foreign currency—the government cannot afford the fiscal consequences of a truly floating currency. Significant depreciation of the Jamaican Dollar (JMD) immediately balloons the debt stock and debt service costs, creating a “fear of floating.”

This leads to the “Attempting the Holy Trinity” behavior: the central bank nominally operates a floating regime with independent rates but frequently intervenes in the foreign exchange market (selling US$1.1 billion in 2025 alone) to manage the exchange rate. This hybrid approach attempts to secure the benefits of all three corners of the triangle but risks incurring the costs of all three: high interest rates to defend the currency, the carrying cost of massive reserves to facilitate intervention, and the fiscal instability associated with currency mismatches. The following chapters will meticulously deconstruct these dynamics, quantifying the costs and analyzing the implications for Jamaica’s long-term economic trajectory.

Part II: The Monetary Trilemma in Practice: “Attempting the Holy Trinity”

2.1 The Evolution of Jamaica’s Exchange Rate Regime

To appreciate the current “Holy Trinity” critique, one must situate it within the historical evolution of Jamaica’s monetary policy. Since the 1970s, Jamaica has oscillated between various exchange rate regimes, from strict pegs to managed floats, often driven by the exigencies of balance of payments crises. The current regime is officially classified as a floating exchange rate within an Inflation Targeting framework, a transition that was solidified over the last decade as part of structural reform programs supported by the International Monetary Fund (IMF).

Under a pure Inflation Targeting (IT) regime, the central bank’s primary mandate is price stability. The policy interest rate is the primary instrument used to manage inflation expectations, and the exchange rate is theoretically allowed to float freely to absorb external shocks. This implies that the central bank should not have a target for the exchange rate. However, the data suggests a significant deviation from this theoretical purity. The critique that Jamaica is “attempting the Holy Trinity” stems from the observation that the Bank of Jamaica (BOJ) exercises a “managed float” that borders on a soft peg, despite maintaining open capital accounts and setting independent policy rates.

The “Impossible Trinity” suggests that Jamaica, having chosen free capital mobility (to attract FDI and portfolio investment) and independent monetary policy (to control local inflation), should accept exchange rate volatility. Yet, data reveals that the BOJ sold US$1.1 billion via its B-FXITT facility over the 12 months ending November 2025. This volume of intervention—equivalent to nearly 17% of the total reserve stock—indicates a persistent refusal to allow the currency to find its market-clearing price solely through private sector supply and demand. By proactively implementing measures to “maintain orderly conditions”, the BOJ effectively attempts to control the price of foreign exchange, thereby trying to secure the third corner of the Trinity.

2.2 The Mechanics of Intervention and the “Fear of Floating”

Why does the BOJ intervene so heavily if it is an inflation targeter? The answer lies in the structural transmission mechanisms of the Jamaican economy, specifically the “pass-through” effect of exchange rate depreciation on inflation and the “balance sheet” effect on sovereign debt.

The “fear of floating” is a well-documented phenomenon in emerging markets where central banks are reluctant to let their currencies depreciate significantly. In Jamaica, this fear is rationalized by the high import content of the consumer basket. Depreciation of the JMD leads almost immediately to higher prices for fuel, food, and intermediate goods, directly threatening the inflation target. Market analysis notes that annual headline inflation is projected to rise sharply to exceed the 4.0% to 6.0% target range by early 2026. In this context, the exchange rate is not just an external price; it is a primary determinant of domestic inflation.

Consequently, the BOJ finds itself in a policy bind. To curb inflation, it maintains a policy rate of 7.0%. However, if US interest rates remain elevated (the Fed target range is 3.50% to 3.75%), the interest rate differential may not be sufficient to prevent capital flight unless the exchange rate is also perceived as stable. If the JMD were to depreciate rapidly, it would unanchor inflation expectations. Thus, the BOJ uses its reserves—the US$6.3 billion stockpile—to intervene.

This creates the “Holy Trinity” conflict. By intervening to stabilize the rate, the BOJ effectively surrenders some monetary independence. It cannot cut rates to stimulate the economy (which is contracting by 1-3%) because doing so would narrow the differential with the US dollar, trigger capital outflows, and force a devaluation that the bank is trying to avoid. The economy is thus straitjacketed: unable to devalue to gain export competitiveness because of inflation/debt fears, and unable to lower rates to boost growth because of exchange rate fears.

2.3 Assessing the Metrics of the Trilemma

Scholars Aizenman, Chinn, and Ito have developed metrics to measure the “trilemma configurations” of various countries, testing the linearity of the trade-offs. Their findings suggest that emerging markets often converge toward intermediate levels—”managed flexibility”—using sizable international reserves as a buffer. Jamaica fits this empirical model perfectly, but the “Deep Financial Risks” critique argues that for a small, open, highly indebted island state, this middle ground is treacherous.

The risk is that “managed flexibility” requires massive reserves to be credible. The US$6.3 billion figure is the market’s assurance that the BOJ can enforce its will. However, this assurance is contingent on the flow of foreign exchange remaining adequate. As noted in economic updates, the current account is expected to deteriorate into a deficit. If tourism receipts falter or oil prices spike (projected to increase by 2.0 million b/d in global production in 2025), the drain on reserves to maintain the “managed” aspect of the Trinity could accelerate.

Furthermore, the “open capital account” component of the Trinity—while intended to attract investment—also facilitates capital flight. Theoretical literature explicitly references the choice: “It can free up capital movement but retain monetary autonomy, but only by letting the exchange rate fluctuate.” By refusing to let the rate fluctuate freely, and refusing to close the capital account, the system relies entirely on the BOJ’s ability to manipulate interest rates and sell reserves. This is a high-wire act. If the reserves are depleted, the system collapses into a forced devaluation, a scenario that has played out repeatedly in Jamaica’s economic history. The current record reserves are a buffer against this, but as the next section will detail, the existence of the debt stock makes the cost of any failure catastrophic.

2.4 The Paradox of Monetary Independence

The claim of “independent monetary policy” is also subject to scrutiny. While the BOJ sets a policy rate, reports indicate that decisions are heavily influenced by the US Federal Reserve’s actions. The Fed’s reduction of rates by 25 basis points provided some breathing room, but the BOJ held its rate. In a truly independent regime, a contracting economy (falling GDP) would prompt a rate cut. The fact that the BOJ cannot cut rates despite a recession suggests that its monetary policy is not truly independent; it is constrained by the need to defend the external account.

Thus, the “Holy Trinity” critique is empirically validated. Jamaica effectively does not have an independent monetary policy suited to its domestic cycle (which needs stimulus); it has a monetary policy dictated by the need to maintain the exchange rate and capital flows. The “Attempt” to have it all results in a policy mix that is pro-cyclical—keeping rates high when the economy is shrinking—thereby exacerbating the downturn in the real sector.

Part III: The Scourge of Original Sin: Sovereign Debt Dynamics

3.1 Defining Original Sin in the Jamaican Context

The concept of “Original Sin” is central to understanding why the “Holy Trinity” trade-off is so lethal for Jamaica. As defined in the economic literature, Original Sin is the inability of a country to issue debt in its own currency to international investors. This forces the sovereign to assume the exchange rate risk. In advanced economies (like the US, UK, or Japan), the government borrows in its own currency. If the currency depreciates, the real value of the debt falls, effectively transferring wealth from foreign bondholders to the domestic government. In Jamaica, the opposite occurs.

Official statistics confirm the severity of this condition: at end-December 2024, foreign currency-denominated debt accounted for 59.1% of total outstanding Central Government debt. With the total public and publicly guaranteed external debt standing at approximately US6.3 billion and total external debt reaching US13.58 billion by June 2025, the exposure is massive. This structural feature transforms the exchange rate from a mechanism of trade adjustment into a mechanism of fiscal solvency.

3.2 The Fiscal Arithmetic of Depreciation

The user query references a specific quantification of this risk: “It costs Jamaica half a billion dollars in foreign debt service repayment each time the local currency depreciates”. While this phrasing is colloquial, the underlying arithmetic is sound and devastating.

Let us reconstruct the fiscal impact based on the data provided. The external debt stock is approximately US$13.6 billion.

• If the exchange rate is J155 : US1, the JMD value of this debt is J$2.108 trillion.
• If the currency depreciates by just 1% (to J156.55), the JMD value of the debt stock rises to J2.129 trillion.
• This represents an immediate increase in the stock of debt by J$21 billion purely due to the valuation effect.

Dr. Andre Haughton’s critique focuses on the debt servicing requirements. He notes that debt servicing increases by millions of USD annually due to depreciation. The “half a billion” figure likely refers to the JMD equivalent of the increased debt service burden over a fiscal year following a moderate depreciation. If Jamaica pays roughly 5% interest on US13.6 billion, the annual interest bill is US680 million.

• At J155, that bill is J105.4 billion.
• At J165 (a ~6% depreciation), that bill becomes J112.2 billion.
• The difference is nearly J7 billion (approx. US45 million) in extra interest payments alone, not counting amortization.

This dynamic creates a vicious cycle. Depreciation increases the debt-to-GDP ratio (since debt is in USD and GDP is in JMD) and the debt service burden. To pay the higher debt service, the government must run larger primary surpluses, taxing the local economy more heavily or cutting spending on services. This austerity reduces growth, which further weakens the currency, restarting the cycle. This is the “Deep Financial Risk” alluded to in the text: the potential for a debt-depreciation spiral that fiscal policy cannot arrest.

3.3 The Policy Straitjacket

The presence of “Original Sin” explains the BOJ’s behavior analyzed in Part II. The central bank cannot treat the exchange rate as a shock absorber because the government’s balance sheet cannot withstand the shock.

• Wealth Effects: As noted in economic assessments, depreciation in countries with Original Sin causes a reduction in net worth. This contractionary balance sheet effect often outweighs the expansionary trade effect (where exports become cheaper).
• Fiscal Dominance: Monetary policy becomes dominated by fiscal imperatives. The BOJ effectively puts a floor under the exchange rate to protect the Ministry of Finance’s budget, even if a lower exchange rate would be better for tourism or manufacturing competitiveness.

Historical analysis highlights this trend: “The increase in total debt was predominantly caused by an increase in foreign debt as a result of exchange-rate depreciations.” This historical fact validates the fear that creates the current policy paralysis. The government is “Committed” to Original Sin because changing the currency composition of debt is a slow, multi-decade process. Until then, they are forced to “Attempt” the Holy Trinity to prevent the exchange rate from triggering a fiscal crisis.

3.4 Mitigation Strategies and Their Limits

The report mentions that “Original Sin” dissipation is associated with high international reserves. The logic is that high reserves reassure investors, reducing the risk premium and potentially allowing the issuance of local currency debt. Jamaica’s accumulation of US$6.3 billion is partly an attempt to execute this strategy. By holding massive USD assets, the government tries to net off its USD liabilities.

However, this is an imperfect hedge. The reserves are held by the Central Bank, while the debt is owed by the Central Government. Accessing the reserves to pay debt service requires the government to buy the USD from the BOJ, which pulls liquidity from the market. Furthermore, as discussed in the next section, holding these reserves carries its own substantial cost, arguably replacing one financial risk with a chronic economic drag.

Part IV: The Reserve Accumulation Controversy: US$6.3 Billion at What Cost?

4.1 The Composition of the Record Reserves

The announcement that reserves have hit US$6.3 billion is treated as a victory. However, a forensic analysis of the sources of these funds suggests caution. Reports explicitly state that reserves will be “buoyed by the various disaster risk financing, multilateral funding and grant flows.” This indicates that a significant component of the reserve growth is exogenous—driven by borrowing (loans) and insurance payouts (catastrophe bonds)—rather than endogenous surplus generation (exporting more than importing).

• Multilateral Funding: Inflows from the IMF, IDB, and World Bank often come with conditionality and are essentially debts or credits that bolster the gross figure but do not reflect the economy’s net earning power.
• Catastrophe Bonds: The receipt of proceeds related to the Caribbean Catastrophe Risk Insurance Facility implies that some of this liquidity is triggered by disaster events (like Hurricane Melissa). While beneficial for recovery, treating insurance payouts as a structural improvement in economic reserves is misleading.

4.2 The Carrying Cost of Liquidity

Reserves are not cost-free. They represent capital that could be deployed elsewhere. The “carrying cost” of reserves is defined as the difference between the cost of acquiring the funds (sovereign borrowing rates) and the return on investing the funds (usually in safe, low-yield US Treasury bonds).

• Cost of Funds: Jamaica’s sovereign bonds often trade at yields significantly higher than US Treasuries due to credit risk (rated ‘BB-‘ or ‘BB’). If Jamaica pays 6-7% on its debt but earns only 3.5-4.0% on the US Treasuries it holds as reserves, there is a negative carry.
• Sterilization Costs: To accumulate reserves, the BOJ buys USD from the market and pays in JMD. This floods the system with Jamaican Dollars. To prevent this liquidity from causing inflation, the BOJ must “sterilize” it by selling BOJ Certificates of Deposit (CDs) to banks to take the money back out. The BOJ pays interest on these CDs.
  • Central bank documents acknowledge that “carrying cost may be prohibitive.”
  • Research notes a general trend where the carrying cost of reserves tends to rise as accumulation expands.
• Fiscal Impact: This interest paid to commercial banks for holding CDs is a quasi-fiscal deficit. It transfers wealth from the public purse to the financial sector. With US6.3 billion (approx. J1 trillion) in reserves, even a 1% net carrying cost represents a J$10 billion annual loss. This is money not spent on hospitals, roads, or schools.

4.3 The “Lazy Capital” Critique

Dr. Haughton and other critics argue that this massive accumulation represents “lazy capital.” By locking up US$6.3 billion in low-yield foreign assets, Jamaica is effectively exporting capital to the United States (financing the US deficit) while its own economy is starved of investment.

Commentary urges the government to “explore more income-generating, productive sectors… instead of borrowing.” The critique is that the focus on building a financial fortress (high reserves) has superseded the focus on building an economic engine. The reserves protect the exchange rate, which protects the debt service, but they do not generate employment or improve productivity. In fact, by keeping domestic interest rates high to sterilize the reserves, the policy actively discourages private sector investment.

4.4 Assessing Reserve Adequacy (ARA)

The BOJ boasts that reserves are 151% of the ARA metric. The ARA metric is an IMF construct that estimates the reserves needed to cover short-term debt, imports, and potential capital flight.

• Over-Insurance: Being at 151% suggests Jamaica is over-insured. While insurance is good, excessive insurance is inefficient. The marginal benefit of the extra 51% in terms of risk reduction is likely lower than the marginal cost in terms of foregone investment.
• Disaster Buffer: The counter-argument, supported by the BOJ, is that Jamaica faces existential climate risks. The contraction of 1-3% due to Hurricane Melissa validates the need for a larger-than-average buffer. However, there is a debate about whether these funds should be held as liquid reserves or invested in resilient infrastructure that would prevent the damage in the first place.

Part V: Structural Distortion: Real Economy vs. Financial Flows

5.1 The Remittance-FDI Imbalance

The structural weakness of the Jamaican economy is illuminated by the ratio of Remittances to Foreign Direct Investment (FDI). This metric reveals whether an economy is powered by domestic production and external confidence (FDI) or by the export of labor and social transfers (Remittances).

• The Data:
  • Remittances (2024): US$3.36 billion.
  • FDI (Annualized Estimate based on data): Historical data suggests FDI flows of roughly US360 million to US500 million.
  • The Ratio: This implies a Remittance-to-FDI ratio of roughly 7:1 to 9:1.
• The Implication: This is a staggeringly high ratio. It indicates that the primary source of foreign exchange is not investors betting on Jamaican businesses, but Jamaican migrants sending money home for consumption.
  • Consumption vs. Investment: Remittances primarily fund consumption (food, utilities, housing), which drives imports. FDI primarily funds capital formation (building factories, hotels, infrastructure).
  • Dutch Disease Risk: High remittance flows can cause “Dutch Disease,” where the influx of foreign currency appreciates the real exchange rate, making the country’s exports (like agriculture or manufacturing) less competitive. This forces the economy to rely even more on remittances, creating a dependency cycle.

5.2 The Productivity Gap

Economic analysis identifies the “productivity gap” as a critical failure. Despite high rates of investment in certain periods, output growth remains sluggish.

• Capital Exportation: Discussions on “capital exportation” suggest that in Jamaica, this manifests as the financial sector (banks, pension funds) preferring to invest in government paper (due to high rates) or foreign assets rather than lending to local SMEs. The banking sector is liquid and well-capitalized, but credit to the productive sector is constrained.
• Crowding Out: The government’s need to service its massive debt and sterilize its reserves keeps the “risk-free” rate relatively high. This establishes a high hurdle rate for private projects. If a bank can earn a safe return lending to the government or holding BOJ CDs, it has little incentive to lend to a farmer or a manufacturer where the risk is higher and the return is uncertain.

5.3 The Social Consequence: Poverty and Inequality

The focus on financial aggregates—reserves, exchange rates, debt ratios—often obscures the social reality. Commentary highlights the human cost of this macroeconomic configuration.

• Fiscal Space: The “half a billion” lost to debt service depreciation is money removed from the social budget. Arguments suggest that fiscal space should be channelled towards social programs to make growth inclusive.
• Regressive Impact: Inflation (driven by exchange rate pass-through) and high consumption taxes (needed to service debt) disproportionately affect the poor. The contraction in the economy coupled with rising inflation creates a “stagflationary” environment that hits the most vulnerable hardest.
• Vision 2030 Critique: Critiques of the current trajectory note that despite the Vision 2030 plan, the “licki-licki” culture (patronage) replaces sustainable infrastructure development. The reliance on the Diaspora (remittances) is seen as a strategic pillar, but without “institutional capacity to leverage these investments into value-added production,” it remains a palliative measure rather than a developmental one.

Part VI: Scenarios and Policy Alternatives

Given the analysis of the “Holy Trinity” trap and the costs of “Original Sin,” what are the potential paths forward for Jamaica?

6.1 Scenario A: Status Quo (The Fortress Approach)

The government continues to prioritize reserve accumulation and exchange rate stability.

• Outlook: Nominal stability remains high. Ratings agencies may upgrade Jamaica due to fiscal discipline. However, growth remains low (1-2%), and the economy remains vulnerable to any shock that exceeds the reserve buffer. The “Productivity Gap” widens as investment is crowded out.
• Risk: If a global recession hits and remittances fall, the Remittance-FDI imbalance becomes fatal. The reserves would burn rate quickly to defend the currency, leading to a potential crisis.

6.2 Scenario B: Aggressive Real Sector Reform (The Haughton/Structuralist Approach)

The government pivots from financial accumulation to productive investment.

• Action: Reduce the primary surplus target slightly to fund infrastructure and education. Accept slightly lower reserves (e.g., 100% of ARA instead of 151%) to reduce carrying costs and lower interest rates.
• Goal: Close the productivity gap. Encourage FDI over remittances.
• Risk: The transition is dangerous. Lower reserves and lower rates could trigger capital flight before the real sector responds. The exchange rate could depreciate, triggering the “Original Sin” debt explosion.

6.3 Scenario C: Dollarization (Abandoning the Trinity)

Some arguments (referenced implicitly in “Impossible Trinity” discussions) suggest abandoning the JMD entirely.

• Action: Adopt the USD as legal tender.
• Result: “Original Sin” vanishes (revenue and debt are in the same currency). The “Holy Trinity” is resolved (no independent monetary policy, fixed rate, open capital).
• Cons: Total loss of policy sovereignty. No lender of last resort. In a hurricane, the government cannot print money to rebuild; it must borrow or beg. Given the frequency of disasters, this loss of flexibility could be catastrophic.

Part VII: Conclusion

The analysis of the text “ATTEMPTING THE ‘HOLY TRINITY’ WHILE COMMITTING THE ‘ORIGINAL SIN’…” in the context of Jamaica’s record US$6.3 billion reserves reveals a profound macroeconomic paradox that defines the nation’s current economic reality.

The record reserves are a testament to defensive success. They represent a formidable insurance policy against the external shocks that have historically ravaged the Jamaican economy. By achieving 151% of the Assessing Reserve Adequacy metric, the Bank of Jamaica has effectively inoculated the country against a liquidity crisis in the short term.

However, this stability is purchased at a high price. The “Deep Financial Risks” identified in the critique are not the risks of immediate collapse, but the risks of structural stagnation and fiscal erosion.

1. The Trinity Trap: By attempting to manage the exchange rate (to protect against debt blowouts) while maintaining open capital markets and independent rates, the central bank is forced into a high-cost equilibrium. It must hold excessive reserves and keep interest rates elevated, which chokes off domestic growth.
2. The Penalty of Original Sin: The foreign currency dominance of the debt stock means that the exchange rate cannot function as a shock absorber. Every depreciation is a fiscal traumatic event, costing the state billions in added debt service (“half a billion” dollars annually in the worst-case scenarios). This forces the state to defend the currency at the expense of the real economy.
3. The Opportunity Cost: The US$6.3 billion in reserves, while safe, represents “lazy capital” that incurs a negative carry. It is wealth parked in Washington and Brussels rather than invested in Kingston and Montego Bay. This contributes to the persistent productivity gap and the reliance on remittances over FDI.

In conclusion, while the headline figure of US$6.3 billion is a marker of resilience, it is also a monument to the constraints imposed by Original Sin. Until Jamaica can alter the composition of its debt to local currency and shift its economic engine from consumption-led remittances to investment-led productivity, it will remain trapped in the Impossible Trinity—forever managing the risks of stability rather than realizing the rewards of growth.
