1. Global Macroeconomic Context and Fiscal Divergence

The global economy in the 2024-2025 period stands at a critical fiscal juncture, characterized by the “Great Divergence” in sovereign debt sustainability. Following the unprecedented fiscal expansion necessitated by the COVID-19 pandemic and the subsequent cost-of-living crisis driven by inflationary shocks, nations are now navigating a landscape of elevated interest rates and slowing growth. The aggregate global public debt has stabilized at historically high levels, yet the aggregate figures mask a profound bifurcation in fiscal health between advanced economies with reserve currency privileges and emerging markets facing acute liquidity constraints.   

The metric of Debt-to-GDP serves as the primary barometer for this analysis. However, it is a metric that demands nuanced interpretation. In the current “higher-for-longer” interest rate environment, the denominator (GDP) has been inflated by rising prices, which has mechanically lowered headline debt ratios in many jurisdictions despite the nominal stock of debt continuing to rise. This “inflation tax” on bondholders has provided temporary relief to sovereign balance sheets, but as inflation recedes, the real burden of debt servicing is surging.

This report provides an exhaustive, country-by-country analysis of general government gross debt ratios, segmented by the United Nations M49 regional classification standards. The analysis draws upon the latest projections from the International Monetary Fund’s World Economic Outlook (October 2025), alongside data from the World Bank and regional central banks, to offer a granular assessment of fiscal solvency across the globe.   

1.1 The Analytical Framework: Gross vs. Net Debt

A critical distinction permeates this report: the difference between gross and net debt. While gross debt represents the total financial liabilities of the general government, net debt subtracts the liquid financial assets held by the state. This distinction is paramount for countries like Singapore, Norway, and Canada, where substantial sovereign wealth funds or pension assets effectively neutralize high gross debt figures. Where applicable, this report will highlight these asset positions to prevent a superficial reading of solvency risks.   

2. North America

The North American fiscal landscape is dominated by the United States, whose debt dynamics exert a gravitational pull on global financial markets. However, the region also encompasses the stable, if highly leveraged, Canadian economy and the unique offshore financial centers of the Atlantic.

2.1 United States of America

The United States occupies a singular position in the global debt architecture. With a general government gross debt-to-GDP ratio estimated between 124% and 128.7% for the 2024-2025 period, the U.S. carries one of the heaviest debt burdens among advanced economies. This elevated ratio is the cumulative result of successive crises—the 2008 financial crash, the 2020 pandemic—and structural deficits driven by entitlement spending and tax policies.   

Despite ratios that would signal distress in a standard emerging market, the U.S. benefits from the “exorbitant privilege” of issuing the world’s primary reserve currency. This ensures a perpetual demand for U.S. Treasuries, allowing the federal government to sustain deficits that exceed long-term growth rates. However, the trajectory is increasingly scrutinized; net interest payments have begun to rival defense spending in the federal budget, creating a long-term crowding-out effect on discretionary investment. The resilience of the U.S. economy, projecting steady growth, helps maintain the denominator, but the numerator continues to expand at a pace that creates persistent political and economic friction.   

2.2 Canada

Canada’s fiscal profile is characterized by a significant disparity between gross and net debt. The gross debt-to-GDP ratio is reported in the range of 110.7% to 113%. This figure aggregates federal liabilities with the substantial debts of sub-national provinces, particularly Ontario and Quebec, which issue their own bonds.   

However, Canada effectively holds a net debt position roughly half of its gross figure, thanks to the massive assets managed by the Canada Pension Plan Investment Board (CPPIB) and the Caisse de dépôt et placement du Québec. These pension assets are distinct from standard government revenues but provide a backstop that rating agencies view favorably. The Canadian economy’s exposure to commodity cycles, particularly oil and natural gas, adds a layer of volatility to revenue projections, yet the country maintains a strong AAA-adjacent credit profile due to robust institutional frameworks and deep domestic capital markets.   

2.3 Bermuda and Offshore Territories

The fiscal metrics for territories such as Bermuda and Greenland are often excluded from standard aggregate datasets like the IMF WEO due to their status as dependencies or specialized economies. Bermuda, for instance, generally maintains low public debt ratios relative to the sheer size of its financial services sector, although the cost of living and import dependence create high per capita operational costs for the government. Greenland, while an autonomous territory within the Kingdom of Denmark, relies heavily on block grants from Copenhagen, rendering standard debt-to-GDP ratios less meaningful as a measure of standalone solvency.   

3. Latin America and the Caribbean

The Latin American and Caribbean (LAC) region presents a dichotomy of fiscal realities. The region contains some of the world’s most distressed sovereign balance sheets alongside nations that have successfully implemented rigorous fiscal rules. The region faces a “middle-income trap” where growth is insufficient to naturally deleverage, necessitating hard fiscal consolidation.

3.1 South America

Brazil, the region’s economic engine, grapples with a high debt burden estimated at 76.5% to 95% of GDP. The wide variance in estimates often stems from the inclusion or exclusion of central bank repo operations in the gross debt definition. Brazil’s primary challenge is the high cost of domestic borrowing; the “Selic” policy rate often exceeds inflation significantly to defend the currency, ballooning the interest bill. The country’s fiscal framework remains a battleground between development needs and market discipline.   

Argentina remains trapped in a cycle of debt distress. Its ratio, hovering between 73.6% and 83.2% , is deceptive. While the percentage is lower than many G7 nations, the composition is toxic: largely foreign-currency denominated and governed by foreign law. The lack of access to international capital markets forces reliance on central bank money printing (monetary financing), which fuels triple-digit inflation and complicates debt sustainability analyses.   

Venezuela represents the most extreme outlier. IMF data often reports “no data” due to the lack of reliable Article IV consultations, but alternative sources and historical extrapolations place the ratio between 164% and 200%. The collapse of the oil industry—the primary source of state revenue—combined with hyperinflation has decimated the GDP denominator, causing the ratio to explode. The debt stock includes billions in unpaid bonds, arbitration awards, and bilateral loans from China and Russia.   

Chile stands as a paragon of fiscal prudence, with a ratio of approximately 41.7% to 43.7%. Supported by sovereign wealth funds derived from copper revenues, Chile has maintained low debt to ensure counter-cyclical buffers. However, social unrest in recent years has created pressure to permanently increase public spending, testing this traditional conservatism.   

Colombia (61.3%) and Peru (32.8%) occupy the middle ground. Peru has historically maintained very low debt due to a constitutional requirement for fiscal equilibrium, although political instability has begun to erode this anchor. Colombia lost its investment-grade rating in recent years but has stabilized its debt trajectory through tax reforms, despite political friction regarding oil exploration policies.   

Ecuador (50.6%) and Bolivia (95%) face distinct challenges. Ecuador is constrained by dollarization, which prevents monetary financing but demands hard currency cash flow for debt service. Bolivia has seen a rapid deterioration in its external accounts due to falling gas exports, leading to a sharp rise in debt and a depletion of foreign reserves.   

Uruguay maintains a robust profile with debt around 66.6% to 70.3%. Known as the “Switzerland of South America,” its debt is high but manageable due to strong institutions, high per capita income, and a favorable maturity profile.   

Paraguay remains one of the least indebted nations in the region at 40.6% to 45.2% , largely due to a small state apparatus and reliance on hydroelectric revenues, though infrastructure needs are pressing.   

3.2 Central America and Mexico

Mexico distinguishes itself with a conservative fiscal stance, maintaining a debt ratio of 49.7% to 59.9%. The current administration has prioritized primary surpluses and limited external borrowing, largely to protect the sovereign rating and the stability of the Peso. This austerity, however, has come at the cost of reduced public investment in critical infrastructure and health sectors.   

El Salvador has garnered global attention for its adoption of Bitcoin, but its traditional fiscal metrics show a debt ratio of 61.1% to 86.9%. The variance reflects different accounting treatments of pension liabilities. The country’s high debt costs effectively lock it out of traditional Eurobond markets, forcing reliance on regional development banks and domestic issuance.   

Panama (56.6%) and Costa Rica (74.18%) are the sub-region’s more developed economies. Panama’s debt increased significantly during the pandemic but is underpinned by the hard-currency revenue stream of the Canal. Costa Rica has engaged in a rigorous IMF-supported fiscal consolidation program to bring its previously exploding debt trajectory under control.   

Guatemala (27.9%) has historically maintained very low debt due to a chronically low tax collection rate—the state simply lacks the revenue capacity to borrow significantly. Honduras (39.8%) and Nicaragua (39.1%) show similar patterns, where low debt ratios reflect underdevelopment and lack of credit access rather than fiscal strength.   

3.3 The Caribbean

The Caribbean region is characterized by small island developing states (SIDS) that are highly vulnerable to external shocks and climate events.

Jamaica is a notable success story of fiscal discipline, having reduced its debt from over 140% to roughly 67.9%  through sustained primary surpluses. This deleveraging has been painful, involving deep cuts to public services, but has restored macroeconomic stability.   

Barbados continues to carry a heavy burden at 94.6% to 133.2% , despite recent restructuring. The island is pioneering “debt-for-nature” swaps and climate-resilient debt clauses to manage this load in the face of hurricane risks.   

The Bahamas (81.5%) faces fiscal pressures from hurricane recovery costs and the pandemic’s impact on tourism. Trinidad and Tobago (58.3%) benefits from oil and gas revenues, which provide a buffer that its tourism-dependent neighbors lack.   

Haiti reports a low debt ratio of 14% , but this is a symptom of state failure; the collapse of governance and security means the state has no capacity to borrow or service debt, and relies almost exclusively on humanitarian aid.   

4. Europe

Europe’s fiscal landscape is defined by the tension between the European Union’s Maastricht criteria—which theoretically cap debt at 60% of GDP—and the reality of post-pandemic economics. The continent displays a sharp North-South divide in debt levels, further complicated by the war economy in the East.

4.1 Western Europe and the Eurozone Core

France, the Eurozone’s second-largest economy, has seen its debt drift upward to 110.6% – 113%. Unlike its neighbor Germany, France has run continuous budget deficits for decades. The political difficulty of enacting pension and labor reforms suggests this ratio will remain elevated, posing a long-term challenge to EU fiscal harmonization.   

Germany remains the fiscal anchor of the continent, with a debt ratio of 62.2% to 66%. The constitutional “debt brake” (Schuldenbremse) legally restricts structural deficits, forcing consolidation even during economic slowdowns. While this ensures solvency, critics argue it has led to underinvestment in public infrastructure.   

The United Kingdom, operating outside the EU framework, faces debt levels of 93.6% to 104.8%. The UK economy has struggled with low productivity growth since the 2008 crisis, and the recent energy shock necessitated massive subsidies. The “gilt” market remains sensitive to fiscal looseness, as evidenced by the 2022 mini-budget crisis, forcing the government to maintain a tighter fiscal stance than it might otherwise prefer.   

Belgium (104% – 110.6%) is another high-debt core country. Its complex federal structure makes expenditure control difficult, as regional governments have significant spending power.   

Austria (81.8%) and the Netherlands (43.7%) generally track the German fiscal cycle, though Austria has slightly higher leverage due to banking sector bailouts in the past decade.   

4.2 Southern Europe (The Periphery)

Greece holds the highest public debt ratio in the EU at 141.9% to 154%. However, this number is less alarming than it appears. The vast majority of Greek debt is held by official creditors (the ESM and EFSF) at highly concessional interest rates with maturities stretching decades into the future. Greece’s annual debt service cost is actually lower than that of Italy or Spain relative to GDP.   

Italy is the primary systemic risk in the Eurozone, with debt at 135% – 135.3%. Unlike Greece, Italy relies heavily on private bond markets. A slowing economy and an aging population create a precarious dynamic where growth struggles to outpace the interest rate on debt (r > g).   

Spain (102% – 107.3%) and Portugal (93.6% – 101.5%) have made progress in reducing deficits. Portugal, in particular, has achieved significant primary surpluses, bringing its debt down from crisis peaks of over 130%. Spain faces structural unemployment challenges that burden the social security system.   

4.3 Northern Europe

The Nordic countries exemplify fiscal conservatism. Denmark (29.1% – 31.1%) and Sweden (34%) maintain very low gross debt levels. Norway (42.5% – 55.1%) is in a unique position; its gross debt is dwarfed by the assets of the Government Pension Fund Global (sovereign wealth fund), giving it a massive net asset position. Finland (82.1% – 89.1%) has seen debt rise more than its neighbors due to an aging population and industrial restructuring.   

4.4 Eastern Europe and Emerging Europe

The war in Ukraine has devastated its economy, driving the debt-to-GDP ratio to 89.8% – 110.4%. This surge is driven by the collapse of GDP (the denominator) and war financing needs. However, a significant portion of international support has come in the form of grants rather than loans, mitigating the long-term solvency impact.   

Russia reports a low debt ratio of 16.4%. This reflects a strategy of “Fortress Russia”—building reserves and paying down external debt to reduce vulnerability to sanctions. With access to Western capital markets cut off, Russia finances its war effort through domestic issuance and energy revenues, keeping the headline debt ratio low despite the intense strain on the economy.   

Poland (55.1%) is ramping up defense spending to record levels, which is expected to push debt higher in the coming years. Hungary (73.5%) has a higher debt burden and faces high interest costs due to inflation and disputes with the EU over rule-of-law funding.   

The Baltic states—Estonia (23.5%), Latvia (46.6%), Lithuania (38%)—remain among the most fiscally prudent in the EU , viewing low debt as a matter of national security to ensure resilience against external shocks.   

Turkey presents a paradox with a low public debt ratio of 24.7%. However, this masks severe economic fragility in the private sector and banking system caused by unconventional monetary policies and high inflation. The sovereign balance sheet is relatively clean, but contingent liabilities are high.   

4.5 Microstates and Others

Monaco and Liechtenstein do not report standard debt-to-GDP ratios in the same manner as larger states. Monaco runs a balanced budget or surplus and has no public debt; its reserves exceed its spending requirements. Liechtenstein similarly reports a 0% debt ratio. The Vatican City (Holy See) runs operational deficits but does not issue sovereign bonds, relying on donations and investment income to cover gaps.   

5. Asia-Pacific

Asia encompasses the full spectrum of debt dynamics: from Japan’s massive domestic ledger to the development-driven borrowing of Southeast Asia and the distress of South Asian frontier markets.

5.1 East Asia

Japan possesses the world’s highest public debt-to-GDP ratio, ranging between 237% and 252%. Conventionally, this would signal imminent default. However, Japan is a unique case: over 90% of this debt is held domestically by Japanese banks, insurance companies, and the Bank of Japan itself. This “home bias” eliminates the risk of capital flight that plagues other debtors. The debt is denominated in Yen, a reserve currency. The challenge for Japan is not solvency, but the fiscal rigidity it creates; even small increases in interest rates significantly impact the budget.   

China reports a central government debt of roughly 24%, but this is misleading. The general government debt, which includes the opaque Local Government Financing Vehicles (LGFVs) used to fund rapid infrastructure expansion, is estimated by the IMF and others at 88.3% to 102.3%. China is currently engaging in a “hidden debt” swap program to bring these off-balance-sheet liabilities onto the official books, acknowledging the scale of the leverage.   

Taiwan maintains a conservative ratio of 27.1%. Its fiscal strength is bolstered by massive foreign exchange reserves and a booming tech sector. South Korea has seen its debt rise to 46.8% – 56.7% , breaking with a history of surplus to address a rapidly aging demographic and low fertility rates.   

North Korea operates a non-market command economy. It does not publish debt statistics, and it has been in default on international loans since the 1970s. Estimates of its GDP are speculative, making a ratio calculation impossible in standard terms.   

5.2 Southeast Asia (ASEAN)

Singapore requires careful interpretation. Its gross debt ratio is one of the world’s highest at 168% to 173%. However, Singapore is a net creditor. The government issues debt not to fund deficits, but to build a liquid bond market and to provide investment vehicles for the Central Provident Fund (CPF). The proceeds are invested by GIC and Temasek, generating returns that exceed the cost of borrowing. Its net debt is effectively zero.   

Indonesia enforces a strict legal cap on its fiscal deficit (3% of GDP) and debt (60% of GDP). Consequently, its debt remains low at 38.8% to 40.2%. This prudence has made Indonesian bonds a favorite for emerging market investors, though it constrains development spending.   

Thailand (63.7%) and Malaysia (70.4%) have higher debt burdens. Malaysia carries significant contingent liabilities from state-owned enterprises (legacy of the 1MDB scandal), while Thailand faces rising household debt that limits the government’s room to tax.   

Vietnam stands out with a low ratio of 32% to 32.9%. Its rapid GDP growth acts as a natural deleveraging mechanism, diluting the debt stock even as the country invests heavily in infrastructure. The Philippines has seen debt rise to 60.7%  due to the “Build, Build, Build” infrastructure program, but maintains an investment-grade rating.   

Laos is in a zone of distress, with debt estimated at 68.7% to 84.7%. Much of this is owed to China for railway and hydro projects, and the depreciation of the Laotian Kip has made servicing this foreign-currency debt extremely painful.   

5.3 South Asia

India carries a high public debt load for a developing economy, at 81.9%. The government argues this is sustainable because it is almost entirely domestic and denominated in Rupees, with a long maturity profile. India’s high nominal GDP growth helps stabilize the ratio, but interest payments consume a large share of tax revenue, limiting funds for health and education.   

Pakistan is in a protracted crisis. Debt stands at 71.3% to 80%. With low foreign reserves and a history of balance-of-payments crises, Pakistan relies on roll-overs from bilateral partners (China, Saudi Arabia, UAE) and IMF bailouts to avoid default.   

Sri Lanka (96.1%) is currently restructuring its debt after defaulting in 2022. The ratio remains high as the economy contracts and the currency stabilizes, but the path to sustainability involves painful austerity and haircuts for creditors.   

Bangladesh (32.2% – 40.2%) has historically had low debt, but recent pressure on reserves and the banking sector has increased vulnerability.   

Afghanistan reported a drop in debt ratio to 47.9% in 2024 from higher previous levels , but this reflects the chaotic economic contraction and isolation following the Taliban takeover, rather than fiscal health.   

5.4 Central Asia

The Central Asian republics generally maintain strong balance sheets due to commodity exports.

• Kazakhstan: 23.7%. Oil wealth allows for a sovereign wealth buffer.   
• Uzbekistan: 31.1% – 35%. Opening up the economy has led to increased borrowing for modernization, but from a low base.   
• Turkmenistan: 4.6%. Extreme isolation and gas revenues keep official debt negligible.   
• Kyrgyzstan (25.9% – 36.6%) and Tajikistan (29.5%) are more vulnerable, relying on remittances and concessional loans.   

6. Middle East and North Africa (MENA)

The MENA region is economically bifurcated. Hydrocarbon exporters in the Gulf are using windfall revenues to deleverage, while hydrocarbon importers face a perfect storm of high food prices, high energy costs, and high interest rates.

6.1 The Gulf Cooperation Council (GCC)

The GCC states generally exhibit robust fiscal health, bolstered by the 2022-2024 oil price cycle.

• Saudi Arabia: 26.2%. The Kingdom is utilizing its fiscal space to fund the massive “Vision 2030” projects (NEOM, Red Sea).   
• Kuwait: 3% – 10.7%. Political gridlock has prevented the passage of a debt law, ironically forcing the government to draw down reserves rather than borrow, keeping debt artificially low.   
• UAE: 31.9% – 32.1%. The federation has a strong net asset position through funds like ADIA.   
• Qatar: 40.8%. Massive LNG revenues have allowed for rapid debt repayment following the World Cup infrastructure build-out.   
• Oman: 35.5%. Aggressive fiscal consolidation has successfully reduced debt from dangerous highs in 2020.   
• Bahrain: 134% – 146.4%. The outlier in the Gulf, Bahrain has limited oil reserves and relies on fiscal support from its wealthier neighbors to sustain its currency peg and service its high debt.   

6.2 The Levant and North Africa

Lebanon is in a state of sovereign default and economic collapse. Its debt-to-GDP ratio is cited between 164% and 211%. The banking sector is insolvent, and the currency has lost over 98% of its value. The ratio is largely academic as the country cannot service the debt.   

Egypt faces a severe solvency test. Debt is estimated at 82.9% to 95.8%. The government borrowed heavily for infrastructure (new capital city) and to defend the currency. With high global interest rates, debt service now consumes more than half of the budget. Egypt is currently under an expanded IMF program to avoid default.   

Jordan (90.2%) relies on foreign aid and grants to maintain stability amidst regional conflict. Tunisia (79.8%) is teetering on the brink of crisis, with a high public wage bill and resistance to IMF reforms making financing difficult.   

Israel has seen its debt ratio rise to 69%  following the outbreak of war in Gaza. The mobilization of reservists and direct military costs have reversed a decade of debt reduction, pushing the fiscal deficit higher.   

Syria and Yemen are conflict zones. Yemen’s debt is estimated at 70.9% , but the state is fractured. Syria has experienced a surge in domestic debt to fund the war, though reliable GDP figures are nonexistent.   

Iran reports a low external debt due to sanctions, but domestic government debt is estimated at 36.8%. The government relies on inflationary monetary financing to cover deficits.   

7. Sub-Saharan Africa

Africa faces a “funding squeeze.” The Eurobond market has largely closed to African issuers due to perceived risk, forcing reliance on expensive domestic debt or conditional multilateral loans.

7.1 Debt Distress Cases

Sudan holds the world’s highest debt-to-GDP ratio, estimated at roughly 272%. This reflects decades of compound interest on unpaid loans, penalties, and the economic devastation of the ongoing civil war. It is in arrears with almost all creditors.   

Eritrea is another extreme case, with debt between 164% and 260%. This is largely domestic debt owed to the banking system in a closed, command economy context.   

Zambia (69.6% – 114.9%) and Ghana (70.5%) are the primary test cases for the G20 Common Framework for debt restructuring. Both defaulted on Eurobonds. Their ratios are stabilizing as they undergo painful haircuts and fiscal adjustments.   

Somalia achieved a major milestone in 2024, reaching the HIPC Completion Point. This triggered massive debt forgiveness, crashing its debt-to-GDP ratio from over 60% down to approximately 6% to 9%. This “reset” offers a rare clean slate in the region.   

7.2 Major Economies

South Africa, the continent’s most industrialized nation, has seen debt rise to 76.9%. Low growth, an energy crisis (Eskom), and a high public wage bill have created a steep yield curve. The market demands a high premium to hold South African debt, exacerbating the fiscal deficit.   

Nigeria has a relatively low debt-to-GDP ratio of 52.9%. However, this metric is deceptive. Nigeria has one of the lowest tax-to-GDP ratios in the world. Consequently, its debt service-to-revenue ratio is alarmingly high, often consuming the vast majority of government income. The issue is not the size of the debt, but the scarcity of revenue.   

Kenya (65.5%) faces acute liquidity pressures with large Eurobond maturities coming due. The government has struggled with tax protests while trying to satisfy IMF fiscal targets.   

Ethiopia (32% – 41.1%) became the third African nation to default in recent years, largely due to the liquidity crunch exacerbated by the Tigray war and foreign exchange shortages.   

Congo (DRC) has a low official debt of 14.6% – 19.3%. This reflects its reliance on resource-backed infrastructure deals with China, which often sit off the sovereign balance sheet but encumber future mineral revenues.   

8. Oceania

The Oceania region is comprised of the mature economies of Australia and New Zealand, and the aid-dependent Pacific Island states.

Australia (43.8% – 50.7%) and New Zealand (45.2% – 51.15%) maintain strong AAA-rated balance sheets. Their debt rose during the pandemic but is stabilizing. Both nations borrow in their own currency and have deep domestic savings pools.   

The Pacific Islands are highly vulnerable. Fiji has a high debt ratio of 78.3% – 79.8% , a legacy of the pandemic which crushed its tourism-dependent economy. Palau (59%) and Maldives (62.4%) face similar tourism-related vulnerabilities.   

Tuvalu (3.6% – 8.7%) and Nauru (14.9% – 17.4%) have low official debt ratios. These microstates rely heavily on revenue from fishing licenses, the “.tv” internet domain (Tuvalu), and Australian processing centers (Nauru), alongside donor grants, rather than debt issuance.   

Papua New Guinea stands at 50% – 51.1%. Its debt is tied to volatile commodity prices (LNG, gold), and it relies on financing from Australia and multilateral partners.   

9. Conclusion: The New Era of Fiscal Hardship

The comprehensive survey of global debt-to-GDP ratios in 2025 reveals a world in fiscal transition. The era of “free money”—where governments could borrow at near-zero rates—is over.

1. Refinancing Risk: The primary danger in 2025 is not just the level of debt, but the repricing of it. As cheap pandemic-era bonds mature, they must be rolled over at significantly higher interest rates. This is creating a “refinancing wall” for countries like Kenya, Pakistan, and Egypt.
2. The Hidden Leverage: Official statistics for China (LGFVs), Laos, and resource-rich African states often understate the true burden due to off-balance-sheet borrowing and collateralized loans.
3. Divergence: While the US and Japan can sustain ratios >100% due to structural advantages, developing nations begin to face distress at ratios as low as 60%. The threshold for safety is not uniform.
4. Asset Buffers: Countries with significant net asset positions (Norway, Singapore, UAE) are fundamentally insulated from the risks that plague net debtors (USA, Italy), highlighting that the gross debt ratio is only one part of the solvency equation.

As the global economy slows, the capacity for countries to grow their way out of debt is diminishing, forcing governments toward difficult choices between austerity, higher taxation, or debt restructuring.
