Pulse Analysis

Safe‑haven currencies have long been dominated by the U.S. dollar, Swiss franc and Japanese yen, each offering investors a refuge when markets turn risk‑off. Historically, the euro’s effective exchange rate barely moved—about a tenth of a percent—during such episodes, limiting its appeal as a defensive asset. The ECB’s latest focus paper revisits this narrative, examining how the euro’s behavior has shifted amid a series of geopolitical flashpoints and policy shocks that have rattled global markets.

In 2025 and early 2026, the euro demonstrated a clearer safe‑haven profile. When the United States imposed new tariffs on April 2, 2025, the euro surged relative to the dollar, mirroring gains in the franc and yen, while Treasury yields unexpectedly rose. A similar pattern emerged after the Department of Justice issued subpoenas to the Federal Reserve and the U.S. hinted at further tariffs on European imports. In both cases, the euro’s appreciation contrasted with the dollar’s depreciation, breaking the conventional risk‑off correlation and suggesting investors view the euro as a viable hedge against U.S. policy risk.

The emerging safe‑haven status of the euro carries practical implications. Portfolio managers may increase euro‑denominated exposure during periods of heightened uncertainty, potentially tightening spreads on German bunds and other euro‑area sovereigns. For the European Central Bank, amplified currency volatility could feed back into inflation dynamics and complicate monetary policy calibration. Moreover, the shift may influence trade negotiations, as a stronger euro can affect export competitiveness. Monitoring the euro’s trajectory will be essential for investors and policymakers alike as geopolitical tensions and policy uncertainty continue to shape global capital flows.
