The European Union is funded by contributions from its member states. At least, that’s what the founding treaties say. In practice, however, the EU has long been taking other paths.
At the core of Europe’s financial architecture lies a clear separation of responsibility and liability: Article 125 of the Treaty on the Functioning of the European Union (TFEU), the so-called “No-Bailout Clause.” It states, unequivocally, that neither the Union nor individual member states may assume the debts of other states. The purpose of this provision is to prevent free-rider effects (moral hazard) at the expense of other member states: each state is responsible for its own obligations.
Still, the clause does not exclude political support, as long as it does not mean assuming the existing debts of other states. A notable example of this practice were the bailout programs for Greece during the sovereign debt crisis one and a half decades ago.
Article 310 TFEU further regulates the EU budget: revenues and expenditures must be balanced every year, and the budget may only be financed through own resources such as member contributions, tariffs, or approved revenues. Independent loans by the EU Commission exceeding the approved framework are prohibited.
Together, these rules form the legal backbone of EU financial policy: no automatic liability, no autonomous EU debt, and only fully covered spending.
This design was deliberately chosen to prevent the emergence of a supra-state in Brussels and to defend the national scope of action of member states against an expanding Brussels bureaucracy.
Theory vs. Practice
That’s the theory. In practice, the EU has steadily increased its presence as a borrower in the bond market. It began in 1976 with the first European Community bond to support Italy and Ireland during the oil crisis. In the 1980s and 1990s, further issues followed for France, Greece, and Portugal—always aimed at demonstrating collective solidarity and easing fiscal tensions.
The 2008/2010 financial crisis marked a decisive turning point: with the European Financial Stabilisation Mechanism (EFSM) and, in 2012, the European Stability Mechanism (ESM), the EU began deliberately supporting over-indebted member states via bond issuance. In 2010, the European Central Bank announced it would purchase euro sovereign bonds on the open market to prevent the collapse of the monetary union—always in close coordination with EU institutions.
The COVID years saw a new dimension in 2020: for the first time, the EU issued Social Bonds under the “SURE” fund. At the same time, the “Next Generation EU” program started, providing around €800 billion in crisis aid. Since 2025, the Union has increasingly relied on so-called “sustainable bonds” (Green Bonds) and plans to issue short-term treasury bills for improved liquidity management.
The EU and ECB now operate in tandem, integrating ever-new financing instruments into the capital markets. The signal to the market is clear: we are ready to meet growing demand for euro bonds. And as collateral, not only the European taxpayer but also the ECB’s virtually unlimited liquidity is on standby. What could possibly go wrong?
