Philip R Lane: Expanding the Supply of Euro Safe Assets

Why It Matters

A deeper supply of euro safe assets would stabilize pricing, lower funding costs for EU sovereigns, and reinforce the euro’s role in the global financial system.

Key Takeaways

• Euro safe asset supply remains insufficient for global demand
• Bunds are the primary euro safe asset but limited in volume
• Inter‑country spread volatility has fallen, indicating stronger euro framework
• Expanding euro‑denominated safe assets could improve market liquidity and stress resilience
• Greater euro safe assets may lower funding costs for EU sovereigns

Pulse Analysis

The concept of a benchmark safe asset is central to any autonomous monetary system, providing a low‑risk anchor for pricing a wide range of securities. In the euro area, Germany's Bunds have long occupied that role because of their high credit rating and deep market. However, Lane’s analysis shows that the absolute volume of Bunds cannot meet the growing appetite of global investors for liquid, euro‑denominated safety, especially when markets face heightened volatility.

Recent reforms after the global financial crisis and the euro‑area debt crisis have tightened fiscal coordination and reduced inter‑country spread volatility, as illustrated by tighter yield differentials across member states. While this convergence signals a sturdier institutional framework, it also masks the structural shortage of truly safe euro assets. Investors seeking a hedge against risk‑on assets now face a bottleneck, which can drive up yields on existing safe instruments and increase funding costs for sovereigns that lack comparable credibility.

Policymakers face a choice: broaden the definition of euro safe assets by incorporating a wider set of high‑quality sovereign bonds, develop a pan‑EU sovereign‑backed security, or create a dedicated euro‑area safe‑asset vehicle. Each option would deepen liquidity, lower risk premia, and enhance the euro’s attractiveness as a reserve currency. For global markets, a more abundant supply of euro safe assets could diversify portfolios, reduce reliance on U.S. Treasuries, and promote a more balanced international monetary architecture.
