OCBC’s Christopher Wong notes that widening Eurozone bond spreads and fragmentation concerns are tightening financial conditions and putting renewed pressure on the Euro. EUR/USD has fallen to its weakest level since May 2025, and while the Dollar could extend gains if French-German spreads stay wide, the ECB’s anti-fragmentation tools are expected to limit systemic stress.

Spreads and ECB backstops in focus

“Rising fragmentation fears are tightening financial conditions through higher sovereign borrowing costs and wider risk premia. This raises the risk that the ECB becomes more cautious on further policy tightening as financial stability concerns begin to compete with inflation risks. As a result, EUR has come under renewed pressure, with EUR/USD falling to its weakest level since May 2025.”

“USD could extend its gains against the EUR if the recent widening in the French-German OAT-Bund spread persists. Wider peripheral spreads tend to tighten Eurozone financial conditions and weigh on EUR sentiment. However, betting on a disorderly sell-off in European bonds remains risky given the ECB’s extensive anti-fragmentation toolkit.”

“The ECB retains powerful tools to limit unwarranted spread widening, including the Transmission Protection Instrument (TPI), which was specifically designed to counter disorderly market dynamics that threaten monetary policy transmission across the Eurozone. While the activation threshold remains high and requires political and economic conditions to be met, the ECB is unlikely to remain passive if market fragmentation intensifies. In the near term, verbal intervention is likely to be the first line of defence should spreads continue to widen.”
