Why High Government Debt Makes a Common European Safe Asset Unlikely
For more than a decade, economists and policymakers have chased the same idea: a common European safe asset — a jointly issued bond that could rival German Bunds or U.S. Treasuries as the euro area's benchmark risk-free instrument. It resurfaces every time Europe hits a crisis, from the sovereign debt turmoil of the early 2010s to the pandemic-era NextGenerationEU program, and again now amid renewed debate over defense spending and EU competitiveness. Yet each time, the idea runs into the same wall: the wildly uneven, and in several major economies dangerously high, levels of national government debt across the bloc.
The Debt Divide That Won't Go Away
A common safe asset only works if the countries backing it are seen as equally creditworthy — or at least close enough that markets won't price in the risk of the weakest link. That condition simply doesn't hold in the euro area today.
<cite index="10-1">Government debt-to-GDP ratios across the euro area vary enormously, with Greece near 143%, Italy around 139%, France above 117%, Belgium past 109%, and Spain above 101%, while countries like Estonia sit at roughly 25%</cite>. That's not a minor spread — it's the difference between a country with almost no debt overhang and ones where debt exceeds their entire annual economic output by wide margins.
The trend lines aren't reassuring either. <cite index="16-1">France's debt is projected to climb from about 116.5% of GDP in 2025 to 129.4% by 2030, and Belgium's from 107.5% to 122.6% over the same stretch</cite>. <cite index="16-1">Even Germany, long the euro area's fiscal anchor, is expected to see its debt ratio rise by more than 9 percentage points, from 64.4% to 73.6%</cite>. Only a handful of countries, notably Spain, Portugal, and Greece, are projected to move in the opposite direction.
Why Investors Are Already Grouping the "BIFs"
Markets have started to notice. <cite index="15-1">Britain, Italy, and France are increasingly being grouped together by investors as economies facing a credibility challenge over their debt, a dynamic distinct from the 2011 solvency crisis centered on Greece, Ireland, Portugal, Italy, and Spain</cite>. As one bond strategist put it, <cite index="15-1">Italy has relatively stable government leadership but so little fiscal room that it can hardly afford to add debt even as its deficits rise, while France has been hamstrung since 2024 by a hung parliament that has blocked meaningful structural reform</cite>.
That matters directly for the safe-asset debate. Any joint bond ultimately rests on the implicit or explicit promise that all participating governments can and will make good on their share. When two of the euro area's largest economies are already being watched nervously by bond markets over their own solo debt, asking them to co-sign a new, larger joint liability becomes a much harder political sell — especially to the currently more fiscally conservative members.
The Political Fault Line: North vs. South
The debt divide maps almost perfectly onto a long-running political one. <cite index="7-1">Spain's proposal to let Brussels borrow up to €850 billion a year to stimulate growth has reignited the debate over common EU debt, but it continues to divide member states, with southern countries pushing to expand shared debt for competitiveness while northern "frugal" countries firmly oppose it and demand stricter fiscal rules</cite>.
This isn't a new argument — it's the same one that has resurfaced after every crisis. <cite index="3-1">The concept of scaling up eurobonds to build deep, liquid safe-asset markets first gained prominence during the euro crisis and has resurfaced repeatedly since, without ever producing a lasting political agreement</cite>. Every time, the countries with cleaner balance sheets worry that joint issuance effectively socializes the borrowing costs of their more indebted neighbors, while the highly indebted countries see it as the only realistic path to cheaper, more stable financing.
What Progress Has Been Made — and Its Limits
It's not that nothing has happened. The EU has quietly become a significant borrower in its own right. <cite index="2-1">By the end of 2026, the European Commission is expected to have roughly €1 trillion of bonds outstanding, making it a larger borrower than Belgium and the Netherlands</cite>. <cite index="6-1">EU bonds have become the second-largest highly rated debt instrument in the bloc after German government bonds</cite>, and <cite index="3-1">EU-issued bonds already carry AAA/AA ratings</cite>.
But scale isn't the same as permanence, and permanence is what a true safe asset needs. <cite index="6-1">Despite rapid growth since the pandemic, EU bonds remain linked to purpose-specific, time-limited programs and don't constitute a unified benchmark asset, and their issuance is planned to decline after 2026</cite>. <cite index="2-1">Because these bonds are still excluded from major sovereign bond indices, their investor base stays limited, which shows up as worse market behavior during periods of stress</cite>.
Some researchers argue the fix is structural — <cite index="2-1">creating a European Debt Agency to consolidate the fragmented issuance currently spread across multiple EU institutions, which could also lower borrowing costs</cite>. Others go further, proposing a dedicated vehicle that would gradually absorb national sovereign debt into a genuine European safe bond — but even proponents acknowledge <cite index="1-1">this would require stronger fiscal backing and discipline than currently exists, and would likely only fully materialize through a future constitutional transition rather than incremental steps</cite>.
The Bottom Line
A common European safe asset is, in theory, exactly what the euro area needs: a deep, liquid, AAA-grade instrument that reduces fragmentation, lowers financing costs for member states, and strengthens the euro's role as a global reserve currency. In practice, it keeps stalling for the same reason — the fiscal starting points of its potential members are simply too far apart. Until France, Italy, Belgium, and Greece bring their debt trajectories under credible control, or the EU builds a robust enough fiscal backstop to absorb that divergence, the political trust required for genuine joint and several liability will remain out of reach. Incremental steps like joint defense and energy bonds may continue, but a true, permanent common safe asset looks unlikely any time soon.
