Wisconsin's Chinn: French-Italian Sovereign Spread Contains Default Risk, Not Comparable to Canada-Germany
Menzie Chinn, Professor of Economics at the University of Wisconsin–Madison, published a brief post on Econbrowser reporting that the 10-year minus 3-month government bond term spread rose in October 2026 for both France and Italy, while the UK spread increased during September. The article cites OECD data to illustrate the term spread trends across five countries—Canada, France, Germany, Italy, and the UK—and highlights a methodological issue: business cycle analysis typically assumes constant or near-zero default risk; however, this assumption is implausible for France and Italy, as evidenced by five-year credit default swap (CDS) prices indicating significant sovereign default risk.
Chinn further notes that historically, the term spread has served as a more effective predictor of recessions for Canada and Germany (see Chinn and Ferrara, 2026). This implies that when investors compare yield curve shapes across different sovereign nations, the French-Italian spread likely contains a credit risk component, whereas the Canada-Germany spread more closely reflects pure interest rate expectations. Consequently, a narrowing or flattening of the French-Italian spread cannot be simply equated with the economic outlook signals implied by similar movements in the Canada-Germany spread.
However, Chinn does not quantify the proportion of spread changes attributable to default risk, nor does he propose a corrected spread metric adjusted for credit risk; his argument serves as a qualitative methodological reminder rather than an actionable alternative model.
