- How European Union government debt has moved from the Maastricht Treaty era to today, and why the crisis pattern looks different from the US or South Africa
- Which five EU countries carry the highest debt burdens, and how each one got there for genuinely different reasons
- Why the 2010 to 2012 euro area sovereign debt crisis happened, and which countries were hit hardest
- How Europe’s debt position compares to the United States and South Africa, the two countries covered in our earlier pieces in this series
This is the third piece in our national debt series, following our earlier articles on the United States $40 trillion debt pile and South Africa’s debt tracked across five presidencies. Europe adds a genuinely different dimension to the comparison: instead of one government and one currency, we’re looking at a union of 27 countries, most sharing a single currency, each running its own budget, inside a set of rules that were specifically designed, and then repeatedly broken, to keep debt under control.
The Maastricht Rules, and Why They Existed
When European countries negotiated the 1992 Maastricht Treaty to create the euro, they wrote in two specific fiscal thresholds that member states were meant to respect: government debt no higher than 60% of GDP, and an annual budget deficit no higher than 3% of GDP. The 60% figure wasn’t arbitrary, it approximated the EU average debt level at the time treaty negotiations concluded, intended as a line member states were already near and could reasonably be held to.
In practice, several founding members were nowhere close. Belgium and Italy both carried debt approaching 140% and 130% of GDP respectively in the early 1990s, more than double the treaty’s own threshold, built up over decades of frequent government turnover and expansive borrowing through the 1970s and 1980s. Both countries pursued serious, sustained fiscal consolidation specifically to qualify for euro membership, and by the time the euro launched in 1999, both had brought their debt down to a remarkably similar 110% of GDP, still far above the 60% target, but a genuine improvement.
2007 to 2014: How the Financial Crisis Became a Sovereign Debt Crisis
By 2007, sustained consolidation across the currency union had pushed EU-wide government debt down to a low of 62.4% of GDP, tantalisingly close to the Maastricht threshold. The 2008 global financial crisis reversed this almost immediately, as governments across Europe bailed out banks and ran stimulus spending in response to the downturn, the same pattern seen in the US and South Africa over the same period.
What made Europe’s experience distinct was what happened next. Because eurozone members share a single currency and cannot devalue their way out of a debt problem individually, markets began pricing individual countries’ bonds very differently based on perceived ability to repay, rather than treating the currency union as one uniform risk. From late 2009, this fear crystallised first around Greece, then spread to Ireland, Portugal, Spain, and Cyprus, a group that financial media at the time bluntly nicknamed the “PIIGS.” EU-wide debt rose from that 62.4% low in 2007 to a peak of roughly 85% of GDP by 2014, with the eurozone specifically peaking even higher, at 86.9%. Some countries within that average saw far more dramatic moves than the headline figure suggests, which is exactly where the five countries below come in.
The Five Most Indebted EU Countries Today
According to Eurostat’s most recent figures, covering the end of 2025, five EU countries carry government debt exceeding 100% of GDP: Greece at 146.1%, Italy at 137.1%, France at 115.6%, Belgium at 107.9%, and Spain at 100.7%. Each arrived at a debt load this size through a meaningfully different path.

Greece: The Original Crisis, and a Genuine Recovery
Greece entered the euro in 2001 reporting debt of roughly 103% of GDP, a figure later revealed to have been understated through statistical manipulation, corrected upward by Eurostat in 2004. When the 2008 crisis hit, Greece’s underlying fiscal position was far weaker than markets had believed, and once that became public in 2009, borrowing costs spiked so severely that Greece required three separate international bailout packages between 2010 and 2018 to avoid default, totalling roughly €280 billion, tied to deep, socially painful austerity conditions. Debt peaked at 182.7% of GDP in 2014, then climbed even higher during the pandemic, to an all-time high of 207% in 2020. Since then, Greece has run consistent budget surpluses (excluding interest payments) and repaid its IMF loans two years ahead of schedule, bringing debt down to 146.1% by the end of 2025, still the highest in the EU by a wide margin, but a genuinely substantial improvement from its peak.
Italy: High Debt That Never Really Went Away
Italy’s story is one of stalled progress rather than crisis and recovery. After matching Belgium’s fiscal effort to qualify for the euro, reaching around 110% of GDP by 1999, Italy’s consolidation largely tailed off in the 2000s while Belgium’s continued. Weak long-run economic growth, rather than a single dramatic event, has been Italy’s core problem: GDP per capita growth lagged most of the eurozone for two decades, meaning the denominator in the debt-to-GDP ratio simply didn’t grow fast enough to outpace new borrowing. Debt reached a new peak of 132% by 2014 and now stands at 137.1%, the second-highest in the EU.
France: The Slow, Steady Creep
France entered the euro comfortably within the Maastricht guidelines, close to the 60% reference value, and stayed relatively disciplined through the 2000s. Its debt trajectory since has been less a crisis than a steady accumulation of annual deficits that were never brought back under control, accelerated first by the 2008 crisis, then significantly by COVID-19 pandemic spending, and more recently by political instability that has repeatedly complicated passing a consolidated budget. France is now the third most indebted country in the EU at 115.6%, and posted one of the larger increases of any member state in 2025 alone.
Belgium: Discipline That Partially Unwound
Belgium’s story runs almost parallel to Italy’s until 2007, then diverges sharply. Starting from an even higher debt peak than Italy in the early 1990s, Belgium’s consolidation continued more consistently through the 2000s, reaching a lower point than Italy by 2007. The 2008 crisis and its aftermath still hit hard, pushing debt to a new peak of 107% by 2014, but unlike Italy, Belgium’s underlying economic growth held up better, containing further deterioration. Belgium’s 107.9% today sits close to its 2014 crisis peak, alongside a persistent structural budget deficit that recent Eurostat data flags as one of the larger increases across the EU in 2025.
Spain: From Eurozone Model Student to Crisis and Back
Spain’s trajectory is the most dramatic reversal of the five. Heading into the 2008 crisis, Spain had one of the lowest debt ratios in the eurozone, roughly 36% of GDP, a genuine fiscal success story built on strong pre-crisis growth. That growth, however, was substantially fuelled by a property and construction boom that collapsed catastrophically after 2008, crashing tax revenue while the government absorbed the cost of a banking sector bailout. Debt crossed 100% of GDP by around 2014 and has hovered near that level since, standing at 100.7% today, the lowest of the five countries on this list but still a dramatic distance from its pre-crisis position.
Where Things Stand Now
At the end of 2025, EU-wide government debt stood at 81.7% of GDP, with the narrower euro area, the 20 countries actually using the currency, at a higher 87.8%, since several of the EU’s lower-debt members, including Poland, Sweden, and Denmark, sit outside the eurozone. Trading Economics forecasts both figures ticking modestly higher through 2026, to roughly 82.8% and 88.1% respectively, suggesting the currency union as a whole has not yet found the kind of turning point South Africa’s most recent budget claimed for itself.
How This Compares to the United States and South Africa
Lay all three of our national debt pieces side by side and a genuinely interesting pattern emerges. The United States, at over 120% of gross federal debt to GDP, carries the highest ratio of the three, but faces the lowest immediate market pressure, protected by the US dollar’s unmatched status as the world’s reserve currency. South Africa, at 78.9%, sits below the EU average of 81.7%, despite having none of the reserve-currency protection either the US or the eurozone collectively provides. And the eurozone’s most indebted members, Greece and Italy, demonstrate something neither the US nor South Africa’s single-currency situation can show directly: what happens when individual governments lose the ability to control their own currency entirely, and must instead convince bond markets, one country at a time, that they can be trusted within a currency union they don’t fully control.
Key Takeaways
- The Maastricht Treaty’s 60% debt-to-GDP threshold was never close to universally met, even at the euro’s 1999 launch, when Belgium and Italy both still carried debt around 110% of GDP
- EU-wide debt fell to a low of 62.4% of GDP by 2007, before the 2008 financial crisis and the subsequent 2010-2012 sovereign debt crisis pushed it to a peak of roughly 85% by 2014
- Greece, Italy, France, Belgium, and Spain are the five EU countries with debt exceeding 100% of GDP as of late 2025, each for a genuinely different underlying reason: manipulated statistics and forced bailouts for Greece, stalled growth for Italy, slow accumulation for France, partially unwound discipline for Belgium, and a property crash for Spain
- EU-wide debt stood at 81.7% at the end of 2025, above South Africa’s 78.9% but well below gross US federal debt above 120%
- Reserve currency status, not the debt ratio alone, remains the biggest single differentiator in how much market pressure a government’s debt load actually generates
Frequently Asked Questions
Which European country has the highest national debt?
Greece, at 146.1% of GDP as of the end of 2025, the highest in the European Union, though down substantially from its all-time peak of 207% recorded in 2020.
Why did the euro area sovereign debt crisis happen if the US and UK had similar financial crises?
Because eurozone members share a single currency and cannot devalue it individually to ease their own debt burden, financial markets began pricing individual member countries’ bonds separately based on each government’s specific fiscal credibility, rather than treating the whole currency union as one uniform risk, a dynamic that doesn’t apply the same way to a country with its own independent currency.
Did any of these five countries ever actually reduce their debt significantly?
Yes. Both Belgium and Italy brought debt down from roughly 140% and 130% of GDP respectively in the early 1990s to about 110% each by the 1999 euro launch, and Greece has reduced its debt from a 207% peak in 2020 to 146.1% today through sustained budget surpluses.
Is Germany not on this list because it has low debt?
Germany’s debt is meaningfully lower than the five countries covered here, generally in the 60s percentage range in recent years, well below the EU average, which is why it doesn’t appear among the five highest-debt EU members.
How does Europe’s debt situation compare to South Africa’s?
The EU’s aggregate debt-to-GDP ratio of 81.7% is slightly higher than South Africa’s 78.9%, though this comparison sits oddly alongside the reserve-currency point made throughout this series: the euro carries meaningfully more global reserve status than the rand, giving eurozone borrowing costs a structural advantage South Africa doesn’t have, even at a broadly similar headline debt ratio.
