Euro zone bonds are displaying a higher level of correlation with their U.S. counterparts than ever before, driven primarily by investors’ intense focus on inflation and interest rates rather than the economic slowdown in Europe. The tight correlations between the two markets have reached record highs in recent weeks, puzzling some bond analysts given the relative weakness of the euro zone economy compared to the United States.
Despite the disparity in economic performance, factors such as inflation and the influence of the U.S. bond market have led to increased correlations between German and U.S. bond yields, with the U.S. bond market playing a significant role in dictating conditions globally.
While the U.S. economy has outpaced Europe’s, with stronger GDP growth and a growing private sector, inflation has become the primary focus of markets on both sides of the Atlantic. The European Central Bank (ECB) typically follows the Federal Reserve’s lead, further contributing to the alignment between euro zone and U.S. bond markets.
The onset of the COVID-19 pandemic and subsequent supply chain disruptions have driven inflation in both the U.S. and the euro zone, leading to similar trajectories in bond yields. ECB Governing Council member Robert Holzmann noted that the ECB tends to follow the Fed with a delay, emphasizing the interrelated nature of the currency areas.
The dominance of U.S. bond yields as a global benchmark has grown over the years, fueled by higher U.S. debt issuance compared to Europe. As a result, when U.S. bond yields move, other markets tend to follow suit, contributing to the strong correlation observed between euro zone and U.S. bonds.
While record correlations are currently prevailing, some investors expect them to decrease as macroeconomic and policy outcomes diverge between the U.S. and euro zone. Divergence in bond markets could also lead to increased volatility in currency markets, which have experienced multi-year lows.
Barclays economists anticipate a potential cut in interest rates by the ECB ahead of the Fed, reflecting the weaker economic conditions in the euro zone. This divergence could impact the performance of German Bunds relative to U.S. Treasuries, presenting opportunities for investors amid evolving market dynamics.
