EU Bonds: Navigating a Tightrope Between Supply, Demand, and Safe Asset Status
European government bond markets are facing a complex interplay of forces. Surging issuance, driven by both national fiscal needs and new EU-level borrowing, is colliding with the European Central Bank’s (ECB) quantitative tightening (QT) policies. This dynamic is sparking debate among market participants about whether balance sheet capacity for bond and repo intermediation is becoming constrained.
The Supply Surge and QT Challenge
The sheer volume of new bond supply is a key concern. Amundi Research anticipates a significant rise in European government bond supply in 2026, with gross issuance potentially reaching €1.4 trillion. This increase, particularly in Germany and France, will inevitably raise refinancing costs, especially for five-year paper. Simultaneously, the ECB’s QT program is reducing its bond purchases, exacerbating the pressure on dealers to absorb the increased supply.
The core of the issue lies in how dealers manage this increased supply. Some argue that their capacity to intermediate bonds and facilitate repo transactions is being stretched. This could lead to wider bid-ask spreads and potentially impact market liquidity.
The Quest for “Safe Asset” Status
Beyond the immediate supply-demand dynamics, a longer-term question is whether EU-issued bonds can evolve into a genuine supranational, euro-denominated safe asset. Currently, the euro area lags behind the US in terms of the availability of such assets. In 2019, the supply of sovereign bonds with a credit rating of AA or higher amounted to just 37% of GDP in EU Member States, compared to 89% of GDP in the US.
Safe assets are crucial for financial stability. They are defined by low default risk, value robustness during economic downturns, and high liquidity. Banks need them to meet liquidity regulations, and central banks rely on them for monetary policy implementation.
Structural Hurdles and Potential Solutions
Despite the increase in EU bond issuance since 2020 – largely in response to the Covid-19 pandemic – these bonds currently trade at a yield premium compared to equally safe sovereign bonds. This isn’t due to credit risk, but rather to their legal status, which excludes them from major bond indices and limits their investor base. This exclusion significantly shrinks demand.
One proposed solution involves exchanging part of national debt for large-scale senior “blue bonds.” This bold move could address the structural shortcomings and broaden the investor base, potentially elevating EU bonds to safe asset status.
ECB’s Role and Collateral Considerations
The ECB’s actions also play a critical role. In 2022, extraordinary demand for sovereign bonds as collateral, coupled with the ECB’s still-high bond holdings, pushed German bond yields below the risk-free OIS rate. This highlights the importance of collateral availability and the impact of central bank policies on bond market dynamics.
Looking Ahead: Balancing Act
The future of EU bond markets hinges on a delicate balancing act. Managing the surge in supply even as ensuring sufficient demand, and addressing the structural issues preventing EU bonds from achieving true safe asset status, will be crucial. The ECB’s monetary policy decisions and potential reforms to the legal framework governing EU bonds will be key determinants of success.
FAQ
Q: What is Quantitative Tightening (QT)?
A: QT is a monetary policy process where a central bank reduces the amount of bonds it holds, thereby decreasing the money supply.
Q: Why are safe assets key?
A: Safe assets are essential for financial stability, providing a reliable store of value and facilitating transactions during times of economic stress.
Q: What are “blue bonds”?
A: “Blue bonds” are bonds specifically earmarked to finance environmental projects, often related to ocean conservation.
Q: What is the OIS rate?
A: The Overnight Index Swap (OIS) rate is a benchmark interest rate reflecting expectations of future overnight lending rates.
