Lane: Diagnostic Challenges for ECB Monetary Policy ## SPEECH DIGEST NEUTRAL low confidence · 31.3k characters read ECB Chief Economist Lane uses his conference keynote to frame a "second wave" of the energy supply shock and to restate the three-criterion framework. He confirms the June and September hikes from 2.00 to 2.50 per cent were prudent and that policy sits on a "middle path" with a measured response to keep inflation in check. The desk read: no cut bias, no pre-commitment, and a genuinely two-sided set of risks that leaves the front end hostage to oil, gas and long-end yields. Direction on the new content is close to neutral, with the second-wave inflation upside offset by the ECB noting that higher long-term rates are already tightening conditions for it. **What’s new: **Nothing new on the rate path: 2.50 per cent and the meeting-by-meeting, data-dependent stance are known. The fresh content is threefold. One, the explicit "second wave" framing since July, with a significant upward shift in oil prices, refining margins and gas, and futures now implying a shallower oil and gas reversion into 2027-28. Two, the statement that recent long-term rate increases "will slow growth and reduce pass-through by more than projected in our September exercise," a dovish substitution worth watching. Three, the colour on contained underlying inflation even as September projections push non-energy inflation to 2.6 per cent on average in 2027. Everything else confirms the prevailing read. ### KEY FINDINGS - Since July there has been a significant upward shift in oil prices, compounded by sharp increases in refining margins and a sustained surge in gas prices, and futures markets now imply the reversion in oil and gas over 2027 and 2028 will be less steep than previously expected. Direct upside to the inflation path and downside to growth from a fresh energy impulse, which keeps the bar to near-term cuts high. - Lane confirms the June and September hikes from 2.00 to 2.50 per cent as prudent, states policy is in the "middle path" with a measured response to keep inflation in check, and says "we are not on a pre-committed rate path." Confirmation of the prevailing read, so near-zero new policy signal and limited expected price action. - The notable recent increases in long-term interest rates "will slow growth and reduce pass-through by more than projected in our September exercise." Market-driven tightening is doing part of the ECB's work, a dovish offset that argues against additional hikes. - Non-energy inflation is 2.3 per cent against a 2.4 per cent pre-shock benchmark and underlying indicators show no upward shift in medium-term inflation has taken hold, even as September projections put average non-energy inflation at 2.6 per cent in 2027. Supports patience now, with the 2027 reacceleration as the hawkish tail that justifies the hold rather than cuts. - The euro area fiscal stance moves from neutral in 2025 to a 0.5 percentage point loosening in 2026, then tightening of 0.4 and 0.2 percentage points in 2027 and 2028. A medium-term fiscal drag that offsets the energy impulse and matters more for the 2027 curve than the front end today. ### FROM THE DOCUMENT Taken together, this means that we remain in the “middle path” for monetary policy, in which a measured response is appropriate to keep inflation in check. It was prudent to raise the policy rate from 2.00 to 2.50 per cent over the course of two projection rounds in June and September, given the energy supply shock and the other developments. However, we are not on a pre-committed rate path. This second wave of the energy supply shock poses direct upside risks to the inflation outlook but also downside risks to the growth outlook. In particular, while growth has been holding up this year, the fiscal impulse is projected to turn from positive in 2026 to negative in 2027 and 2028, and the notable recent increases in long-term interest rates will slow growth and reduce pass-through by more than projected in our September exercise. It is a pleasure to welcome you to the 2026 edition of the ECB Conference on Monetary Policy: bridging science and practice. In this speech, I lay out some diagnostic challenges in determining the appropriate ECB monetary policy. [1] Our interest rate decisions are based on three criteria: (i) our assessment of the inflation outlook and the risks surrounding it, in light of the incoming economic and financial data; (ii) the dynamics of underlying inflation; and (iii) the strength of monetary policy transmission. Taking these criteria in turn, the medium-term component of the inflation outlook plays a central role in setting the appropriate monetary policy. [2] With multiple shocks hitting the economy and playing out over different time horizons, a primary diagnostic task is to distil the medium-term component of inflation.
