ECB October hold expected as French bond stress does the tightening
Economists expect the European Central Bank to leave its deposit rate at 2.5% on Thursday despite 3.8% inflation, arguing that the surge in French and German bond yields has already tightened policy.
On paper, eurozone data argue for another rate increase. In practice, an ECB October hold is the consensus for Thursday, because the bond market has done some of the central bank's work for it.
What happened
Headline inflation reached 3.8% in September, its highest since 2023, as energy prices climbed above the ECB's adverse scenario, RSM noted in its preview. Core inflation rose to 2.5%, only 0.1 percentage point above its level before the Iran conflict. RSM expects the deposit rate to stay at 2.5% this week and a quarter-point increase in December, taking it to 2.75%.
The reason to wait is France. A fiscal and political crisis pushed the gap between French and German 10-year yields to its widest since the 2011 debt crisis, around 175 basis points by RSM's estimate. ING's Carsten Brzeski calculated that the rise in German yields since September has roughly the same effect as a 25 basis point hike, and closer to 50 basis points for France, according to FXStreet.
The euro has felt it. The single currency traded at $1.1165 on Tuesday, down about 1.4% this month, as worries about French debt weighed, CNBC reported.
Why it matters
Lagarde has argued that the energy shock cannot simply be ignored, yet that the response should stay measured, and that wages have not reacted materially so far, RSM noted. Governing Council member Kazāks said there is no immediate need to rush on rates. Brzeski expects the meeting to be uneventful on action but not on words, with the December projections the real decision point. We have tracked the French strain in our report on the French budget and Eurogroup stance and the energy driver in our Brent oil shock long read.
A surprise hike would hurt a stressed debt market, RSM argued, which is one more reason the ECB October hold looks safe. The risk lies further out: low gas storage and a strong El Niño, which ECB research says could lift crop prices by about 9%, could push the bank to tighten more in 2027.
What's next
The decision comes Thursday, followed by Lagarde's press conference, according to CoinDesk's calendar. Markets will listen for any hint on December and on the Transmission Protection Instrument, which RSM said may come into play if contagion from French yields spreads. An ECB October hold would also leave the euro sensitive to the Fed's message a day earlier. RSM's full reasoning is in its ECB preview.
The call
We say the ECB will leave rates unchanged at its October meeting. Polymarket's "Will the ECB announce no change at the October 2026 meeting?" market priced Yes at 98% at 08:21 MSK on Oct. 27. Every preview we read points to a pause, and a surprise move would add stress to an already strained French bond market.
