ECB Raises Rates Amid Inflation Concerns
On September 10, the ECB Governing Council decided to raise the three key interest rates by 25 basis points, bringing the deposit rate to 2.50%. The central bank’s staff projections now see headline inflation averaging 3.0% in 2026, 2.5% in 2027, and 2.1% in 2028, reflecting the ongoing impact of energy prices and geopolitical tensions.
German Bund Yields Hit Highest Level Since 2011
Following the ECB’s decision and surging oil prices, the yield on the 10-year German Bund rose to approximately 3.50%, its highest level since 2011. The "Euro-Bund-Future" fell by 0.42% as investors reacted to the combination of higher rates and an oil price shock, marking a significant shift in the cost of borrowing for Germany.
French OAT-Bund Spread Widens to Post-2012 Highs
The spread between French 10-year OATs and German Bunds reached approximately 94 basis points on September 10, with French yields hitting 4.44%. Le Monde reports that this level of divergence has not been seen since the 2012 debt crisis, driven by market concerns over France’s public accounts and political capacity for reform.
Italian BTP-Bund Spread Surges to 88 Basis Points
Italian 10-year BTP yields climbed to 4.38%, pushing the BTP-Bund spread to 88 basis points. The widening spread reflects heightened risk premiums due to global instability, rising interest rates, and domestic political uncertainties, with Italian media noting this is a significant jump from previous weeks.
Local view
In Germany, financial media highlighted the psychological impact of the Bund yield surpassing 3.40%, with finanzen.net noting it was the first time since 2011 that yields had reached such heights before an ECB decision. Investors are closely watching how the new rate environment affects savings products and mortgage rates.
In France, La Tribune emphasized that France is now paying nearly three times the rate of China for borrowing, with the OAT yield at 4.44% signaling a severe stress on the sovereign debt market. The publication argues that while immediate refinancing costs are manageable, the persistent high spread will gradually increase the interest burden.
