Speaking Tuesday in Finland's parliament, Rehn said France is not alone, noting many countries have faced similar market pressure. He described the widening as "somewhat" broader and linked it to a mix of worldwide dynamics and France's own situation.
Rehn said, "Sovereign bond yields are driven by two main factors - higher capital needs from the private sector and bigger deficits in the public sector driving up the cost of capital," pointing to large investments by artificial intelligence companies as an example. Against that backdrop, the extra yield on 10-year French notes versus bunds exceeded 150 basis points and hit 153, the highest since Oct. 2.
Rehn added, "All euro-area countries must bring their public deficits under control and thereby ensure their debt sustainability." He said this applies to France and to Finland. France has been working to rein in a sizable fiscal shortfall and heavy debt burden, while also contending with new cost-of-living demonstrations and incidents of looting. Given market turbulence tied to France's budgetary strains, ECB intervention appears improbable.
