French yields hit near 20-year high as OAT-Bund spread widens
On September 9, the yield on France’s 10-year government bond (OAT) reached 4.3%, its highest level in nearly two years, pushing the OAT-Bund spread to 85.3 basis points. This surge reflects investor nervousness over France's budget discussions and deteriorating public accounts, with the debt-to-GDP ratio at 115.7%. The widening spread highlights growing market skepticism about France's fiscal trajectory compared to Germany's.

ECB poised for "insurance" hike amid energy-driven inflation
Markets are pricing in another 25 basis point hike by the European Central Bank on Thursday, September 11, described by analysts as a move "just for insurance" against persistent inflation. The decision comes as oil and gas prices spike, with Brent crude touching $100, raising concerns that energy costs will feed into household and business inflation expectations. The ECB is expected to maintain its commitment to stabilizing inflation at the 2% target in the medium term.

German Bund auction sees strong demand despite high yields
The German Finance Agency successfully placed €5.5 billion in 10-year Bunds on September 9, with a bid-to-cover ratio indicating robust investor appetite. The average yield for the auctioned Bunds was 3.39%, slightly lower than previous sessions but still near a 15-year high. This strong demand suggests that despite rising yields, German debt remains a preferred safe-haven asset within the Eurozone.

Italian BTP-Bund spread stabilizes as yields hover near 4.2%
Italy's 10-year BTP yield closed at 4.26% on September 9, with the BTP-Bund spread widening slightly to 84 basis points after a brief dip to 81.6 basis points the previous day. The stability in the spread suggests that Italian fiscal risks are currently priced in, though investors remain cautious ahead of the Treasury's September auctions.

Local view
French media outlets like Le Figaro and BFMTV are highlighting the historic nature of the French yield surge, noting it hasn't been seen since the 2008 financial crisis. In Germany, Tagesschau and Morgenpost are focusing on the impact of higher Bund yields on mortgage rates (Bauzinsen) and savings accounts, framing the ECB's potential hike as a signal for savers. Italian financial press (ANSA, Quifinanza) is tracking the daily fluctuations of the BTP-Bund spread, emphasizing the relative stability compared to the volatility in French markets.
