NextFin News - The European Central Bank is at the upper bound of neutral territory and may have to push interest rates into mildly restrictive ground if energy-driven inflation persists, Bundesbank President Joachim Nagel said on Tuesday, underscoring the Governing Council's vigilance twelve days after a 25 basis-point hike left the deposit rate at 2.50%.
Joachim Nagel, president of the Deutsche Bundesbank and a voting member of the ECB's Governing Council, delivered a two-part message that captures the bind facing Europe's central bank. Speaking at an event hosted by the Society of Professional Economists in London on 22 September, Nagel said he was "not so concerned" that wages would react to the current inflation shock the way they did in 2022 — but he warned that the longer high energy prices endure, the greater the risk of second-round effects spreading through the euro area economy.
"The best we can do to avoid second-round effects is to bring the inflation rate down now. We all know that if that is going on longer, we will see some second-round effects."
The remarks come twelve days after the ECB raised its three key interest rates by 25 basis points at its 10 September meeting in Berlin, lifting the deposit rate from 2.25% to 2.50% — the second increase this year as the Middle East conflict re-escalated, pushing oil toward $110 a barrel and lifting euro-area headline inflation to 3.3% in August, far above the bank's 2% target. Energy price inflation alone hit 14.3%, while inflation excluding energy and food edged down to 2.4% from 2.5% in July.
The combination of the two statements — calm on wages, alert on energy — is the crux of the story. It tells markets that the ECB sees the inflation shock as still containable, but not contained. And it leaves the door open to further tightening at a moment when the policy rate has only just reached what Nagel calls the top of the neutral range: the zone that neither stimulates nor restrains the economy.
That distinction matters because the ECB's own estimated neutral band runs from 1.75% to 2.50%. At 2.50%, the deposit rate sits at the ceiling of neutrality. Any move beyond it would, by the bank's own yardstick, shift monetary policy into restrictive territory — and Nagel has explicitly said he will "not exclude" that step if the price picture warrants it.
The policy backdrop has shifted quickly. The ECB raised rates in June for the first time since 2023, bringing the deposit rate to 2.25% after eight cuts had previously taken it down from a peak of 4.00%. At the time, policymakers described the move as a response to upside inflation risks from the conflict. The September increase, widely expected, marked the second step in what officials describe as a meeting-by-meeting recalibration rather than a pre-committed hiking cycle. ECB President Christine Lagarde stressed after the decision that the Governing Council is "not pre-committing to a particular rate path," a phrase that has become the bank's shield against being boxed in by volatile energy markets.
The Mechanism: Why Energy, Not Wages, Is the Transmission Channel That Matters
Central banks do not fear a supply shock itself; they fear the shock becoming embedded. An oil spike raises the price level once. A wage-price spiral raises the inflation rate persistently. The ECB's entire reaction function since the Middle East conflict re-escalated has been built around stopping the first from becoming the second.
Nagel's London remarks are a calibrated read of where that process stands. He said no "significant" second-round effects had materialized, even while acknowledging that core inflation remains "too high." The data back his relative calm on labour. Services inflation — the wage-sensitive component that policymakers watch most closely — eased to 3.0% in August from 3.3% in July. Compensation per employee grew at a 3.3% annual rate in the second quarter, down from 3.5% in the first quarter, and rising productivity helped contain unit labour cost growth, which slowed to 2.6%. On those measures, the wage channel is cooling, not accelerating.
The energy channel is the open wound. Energy inflation at 14.3% in August is not a rounding error; it is a direct pass-through of oil near $110 and a widening Strait of Hormuz risk premium. Nagel's conditional logic is simple and deliberate: if energy prices stay elevated, households and firms begin to build them into contracts, wage demands, and pricing decisions. That is when a one-off price-level adjustment becomes a persistent inflation rate — and that is when neutral rates stop being enough.
This is why "vigilant" is doing more work than a ceremonial adjective. A central bank that is confident second-round effects are absent can afford to wait. A central bank that sees the risk as live but not yet realized has to hold policy at the ready — which is precisely what "agile" and "meeting-by-meeting" language signals. Nagel put it directly: "We have to keep our flexibility, we have to become agile as central bankers."
Cyclical or Structural: A Cyclical Shock Sitting on a Structural Floor
The right framing is not either/or. The energy price spike itself is cyclical — a geopolitical event that will mean-revert once the conflict premium drains out of the oil curve, as it did after the initial 2022 invasion shock. ECB staff projections anticipate exactly that: headline inflation falling to 2.5% in 2027 and 2.1% in 2028, back near target without further dramatic tightening.
But the floor beneath it has shifted structurally. The ECB's own accounts from the July meeting recorded that some Governing Council members argued rates "needed to move into mildly restrictive territory," and the bank now sees core inflation at 2.5% in 2026 and 2.6% in 2027 — above target throughout the projection horizon. Geoeconomic fragmentation, higher defence spending, and a Europe re-wiring its energy supply are not one-off impulses; they are a higher-variance, higher-cost operating environment. Nagel himself has pointed to this, arguing that Europe must withstand geoeconomic fragmentation and that productivity gains from artificial intelligence could eventually offset some of the inflationary pressure.
The policy implication is asymmetric. If the shock is purely cyclical, today's 2.50% is likely sufficient and the ECB can ride the disinflation down. If the structural floor is higher than the 2% target for longer, then neutral itself is higher than previously estimated, and "mildly restrictive" may require less additional tightening than markets fear — but it also means the terminal rate does not come down as fast as the bond market is pricing. Either way, the era of assuming rates will quickly return to the post-2012 low is over.
The Second-Order Question: What the Market Has Priced, and What It Has Not
Markets priced the 25 basis-point September hike with near certainty — LSEG data showed a 100% probability ahead of the meeting. The euro nonetheless slipped 0.19% to $1.1612 immediately after the decision, and the dollar rose, a tell that the move was treated as a "sell the news" event rather than a fresh hawkish signal.
The first-order read is obvious: one more hike is coming if energy holds up. That is priced. What is less settled is the terminal rate, and here the dispersion is wide. A Deutsche Bank survey of its clients showed no consensus on where the cycle ends: more than a third saw a 2.75% peak, one in four saw 2.50% as the endpoint, and another quarter saw 3.00%. Aviva Investors' head of rates, Ed Hutchings, put the risk plainly: with "more than a further two hikes priced, things may well have gone too far."
The second-order implication runs through the euro-area yield curve and the single currency. If Nagel's conditional hawkishness is validated by sticky energy prices, the short end of the curve reprices higher and the euro finds support — but only if the ECB's credibility holds. If the shock fades and growth deteriorates, the curve bear-flattens and the ECB is left holding a rate that is restrictive by accident rather than by design. That is the asymmetry Nagel is trying to preserve optionality against, which is why he rejected forward guidance as "not the best approach to really conduct monetary policy" in the current environment.
Germany adds a wrinkle to the calculus. Nagel said German growth, which the ECB projects at 0.9% for 2026, could end the year "at around 1%," up from an estimate of "roughly 0.6%" several months ago. "This is good news," he said. A stronger German print reduces the political cost of further tightening, but it also raises the question of whether the ECB's growth projections are lagging the same resilience that forced the upward inflation revisions.
The Counter-Thesis: Wait, and the Problem Solves Itself
The strongest case against further tightening is the one Nagel himself partly endorses: wages are not spiraling, second-round effects have not materialized, and the energy shock is a supply phenomenon that monetary policy cannot fix. Raising rates into restrictive territory cannot lower the price of oil; it can only lower demand enough to offset it. With growth already fragile — the ECB projects just 0.9% for 2026, 1.4% for 2027, and 1.5% for 2028 — overtightening risks tipping the euro area into a slowdown that brings inflation down through the unemployment channel rather than the supply channel. That is the costly route, and it echoes the mistake the ECB made in 2011, when it raised rates twice into the early stages of the sovereign-debt crisis before reversing course as the euro-area economy contracted.
Nagel answers this by narrowing the trigger. He is not calling for a pre-emptive hike on growth data; he is conditioning the next move on the inflation picture over "the next months," with energy prices as the leading indicator. In his framing, the cost of waiting is not a recession — it is entrenched expectations. Once households and firms stop believing the 2% target will be met, the real policy rate falls even if the nominal rate is unchanged, and the bank loses control of the inflation path. That is the scenario his "not relaxed" posture is designed to prevent.
The falsifying signal is concrete: if core inflation (excluding energy and food) prints at or below 2.0% year-over-year for two consecutive months while services inflation holds at or below 2.5%, the case for moving into restrictive territory collapses, and the ECB's next move is more likely to be a cut than a hike. Conversely, if energy inflation stays above 10% and core holds above 2.5% into the December meeting, a further 25 basis-point move is the base case.
Outlook: Three Scenarios for the Path Beyond Neutral
The base case is one more 25 basis-point hike — most likely at the December meeting, as Aberdeen economist Felix Feather expects — taking the deposit rate to 2.75%, followed by a hold while the energy shock decays. JP Morgan Private Bank strategist Patrick Ernst captured the door the Governing Council has opened: "One hike is not a ceiling." The upside case for rates is a re-escalation in the Middle East that pushes oil materially above $110 and keeps headline inflation above 3.5%; that path ends near 3.00% in 2027. The downside case is a rapid de-escalation and a sharp energy-price decline, which would let the ECB stop at 2.50% and begin discussing cuts by mid-2027.
Across time horizons, the signals point in different directions. In the short term, liquidity and headline risk dominate: every oil spike and every hawkish comment lifts the two-year yield and supports the euro. Over the medium term, fundamentals matter more, and the ECB's growth projection of 0.9% for 2026 is a thin cushion against cumulative tightening. Over the long term, the structural question — whether neutral itself has risen in a fragmented, re-armament-heavy Europe — will determine whether "mildly restrictive" is a brief pause or a new normal.
For investors, the asymmetry is clear. Rate-sensitive assets — euro-area peripheral bonds, growth equities, and the euro itself — are positioned for a data-dependent ECB that hikes once more and stops. The risk is not that the bank surprises with aggression; it is that it is forced into aggression by a supply shock it cannot control. Nagel's vigilance is not a threat. It is a contingency plan.
The ECB is not trying to talk rates higher. It is trying to keep the option open — and in a world where oil prices are set by geopolitics, optionality is the only credible policy left.
