NextFin News - Can higher interest rates protect the euro area from another inflation shock? Christodoulos Patsalides, an ECB Governing Council member and governor of the Central Bank of Cyprus, said no: monetary policy can restrain demand and keep inflation expectations anchored, but it cannot prevent wars, fiscal strains or supply-chain disruptions. His warning comes as the ECB’s September baseline projects euro-area inflation at 3.0% in 2026, 2.5% in 2027 and 2.1% in 2028, while policymakers assess how an energy shock passes through to wages, services and expectations.
The distinction matters because the policy problem has changed. A conventional demand shock can be cooled by making borrowing more expensive. A war, energy shortage or trade interruption raises costs while weakening output. Higher rates can suppress second-round effects, but they cannot produce gas, reopen a shipping lane or repair a fiscal balance. Patsalides’ point is not a case for easy money. It is a boundary marker: rates are a stabilizer, not an insurance policy.
The argument also places a limit on what investors should infer from a rate signal. A more restrictive central bank may be responding to inflation persistence rather than causing the original inflation. Conversely, a pause does not prove that policymakers are comfortable with above-target prices; it may reflect the judgment that additional demand destruction would not repair the supply problem. The meaning of rates depends on which part of the shock they are trying to contain.
The Shock Is Outside the Rate-Setting Room
The ECB’s recent analysis separates the initial shock from the conditions that determine whether it becomes persistent. Its policy decisions are based on the inflation outlook and risks, underlying inflation dynamics and the strength of monetary-policy transmission. An energy price spike can lift headline inflation immediately; the monetary question is whether firms raise prices broadly, workers seek compensation, households change expectations and financial markets begin to doubt the central bank’s target.
That transmission was visible in the ECB’s official August data. Euro-area inflation rose to 3.2% from 2.9% in July. Energy inflation rose to 14.3% from 10.3%, while inflation excluding energy and food edged down to 2.4% from 2.5%. The combination matters: the headline shock was intensifying even as the underlying measure was not yet broadening in the same way.
Those figures describe a split economy. The energy component can move quickly because it reflects internationally traded prices and regulated pass-through. Underlying inflation tends to adjust more slowly because it is tied to wages, rents, services contracts, financing costs and firms’ pricing decisions. That lag is why a central bank cannot wait for every consequence to appear before deciding whether expectations are at risk. It must distinguish a temporary price-level shift from a process that keeps generating new increases.
The ECB’s September projections put the baseline at 3.0% headline inflation in 2026, followed by 2.5% in 2027 and 2.1% in 2028. Inflation excluding energy and food was projected at 2.5% in 2026, 2.6% in 2027 and 2.3% in 2028. Growth was projected at 0.9% in 2026, 1.4% in 2027 and 1.5% in 2028. Those figures describe a difficult trade-off: inflation remains above target while growth stays positive but subdued.
The projection path is not a promise that shocks will disappear. It is a conditional baseline built on assumptions about energy prices, pass-through and the behavior of households and firms. If the assumptions hold, the initial price shock gradually loses force. If a second shock arrives before the first has cleared the system, the path can shift without any single forecast being irrational at the time it was made.
The ECB’s account of its Sept. 9-10 meeting said energy developments continued to drive financial markets and that higher energy and food-price concerns pushed expectations for inflation and policy rates higher. It also said longer-term inflation expectations remained anchored and that second-round effects had not been observed so far. That is the narrow window in which monetary policy can work: not against the first jump in energy prices, but against the behavior that follows it.
“A central bank’s monetary policy cannot solve wars, fiscal problems, or supply chain issues,” Christodoulos Patsalides, an ECB Governing Council member and governor of the Central Bank of Cyprus, said in Nicosia on Monday.
The quote is blunt because every shock creates the same temptation: ask whether the central bank is doing enough. The more useful question is whether it is being asked to solve the wrong problem.
Higher Rates Work Through Demand, Not Supply
Higher rates can still be necessary after an external shock. They weaken interest-sensitive demand, slow credit creation and reduce the ability of firms to pass every cost increase into final prices. They also signal that the central bank will not accommodate a temporary shock with permanently easier financial conditions. But these effects arrive with a lag, while an energy or supply shock hits prices immediately.
This timing mismatch can produce an uncomfortable combination of outcomes. The initial shock raises inflation. The response to prevent persistence restrains consumption, investment and housing. If the shock fades, the economy absorbs the cost of tighter policy after the original problem has passed. If the shock persists, rates can reduce demand without restoring supply. The central bank then faces a choice between tolerating above-target inflation and creating a larger output loss.
Transmission also differs across borrowers. A household refinancing a floating-rate mortgage can feel a policy move quickly, while a company with fixed-rate debt may not face the same pressure until it rolls over funding. A small business dependent on bank credit may cut investment before a large firm with access to capital markets. The aggregate effect therefore arrives through a chain of balance-sheet decisions rather than a single switch.
That chain matters for inflation. Weaker household demand can reduce firms’ pricing power, but weaker investment can also reduce future supply capacity. A manufacturer that postpones equipment spending because financing is expensive may lower demand today while adding to capacity constraints later. Monetary policy can therefore improve the inflation outlook through demand while worsening some supply bottlenecks if restraint lasts too long. The appropriate response depends on whether the bottleneck is temporary or becoming embedded.
ECB Executive Board member Philip Lane described the uncertainty in an Oct. 1 interview published by the ECB. The institution’s scenarios make different assumptions about oil and gas prices, the strength of second-round effects and the speed at which energy prices pass through to the wider economy. Lane said energy prices were higher than expected in the baseline and that pass-through to the rest of the economy remained uncertain.
The mechanism is not symmetric. A rate increase can reduce demand for a mortgage, a car or a capital project. It cannot increase the supply of imported fuel. It may, however, prevent a temporary loss of purchasing power from becoming a wage-price cycle. That is why the relevant indicator is not headline inflation alone. It is the interaction between energy, wages, services, inflation expectations and margins.
The ECB’s September meeting account said higher costs had appeared most clearly in non-energy goods prices and that pipeline pressures were evident in imported and intermediate goods. It also said a cooling labor market and moderating wage growth could limit second-round effects. The evidence points to a transmission channel that is active but incomplete: the shock is spreading through costs, yet it has not become a generalized demand-driven inflation process.
This is a cyclical policy cycle confronting a structural shock environment. The rate cycle is cyclical because weaker demand and eventual disinflation can reverse the need for restraint. The drivers of shocks are more structural: geopolitical conflict, energy dependence, fragmented trade and fiscal pressure do not automatically disappear when borrowing costs rise. Treating both as one problem creates the wrong benchmark. Rates may mean-revert; vulnerability to repeated supply shocks may not.
The Second-Order Risk Is the Policy Reaction
The first-order effect of an energy shock is higher inflation. The second-order effect is a repricing of policy, bonds and fiscal capacity. When inflation and policy expectations rise, longer-term yields can rise even as near-term growth weakens. Governments then face higher debt-service costs precisely when households and firms are demanding compensation for the shock.
The ECB’s Sept. 9-10 account said market attention had turned to a global rise in long-term yields amid a resilient euro-area economy. The central bank has also warned that higher global long-term rates could slow growth and alter the pass-through from energy prices. This is the cross-market channel that a simple “higher rates fight inflation” narrative misses: the policy response can tighten financial conditions beyond the short rate, while the shock itself damages real incomes.
Long-term yields incorporate more than the expected path of the policy rate. They also reflect inflation compensation, fiscal risk, growth prospects and the premium investors demand for holding duration. A supply shock can therefore create opposing forces. Weaker growth pulls yields lower, while higher inflation risk and greater government borrowing can push them higher. The central bank controls the short policy instrument, but it does not control every component of long-term financing conditions.
This distinction is especially important for highly indebted governments. A broad subsidy can soften the immediate hit to households, but it may preserve demand and increase borrowing needs. A narrow transfer can protect the most exposed groups with less aggregate stimulus, but it may not prevent the shock from reducing consumption elsewhere. The design determines whether fiscal policy absorbs the shock or amplifies the monetary dilemma.
Fiscal policy becomes the hinge. If governments broadly offset the energy shock, they protect household income and demand, but they can also delay adjustment and require a larger monetary-policy response. If fiscal support is narrow and temporary, it can limit distributional damage without fully neutralizing the price signal. If it becomes permanent, the central bank may face a larger inflation problem and higher borrowing costs.
The ECB’s Oct. 5 diagnostic work said expansionary fiscal measures would reduce the scale of demand destruction and could require a larger monetary-policy response. That does not mean fiscal support is always wrong. It means the composition and duration of support determine whether it complements monetary policy or fights it.
This is where Patsalides’ warning becomes more than a statement about central-bank limits. It shifts responsibility toward the parts of the system that can affect supply resilience, energy diversification, defense, infrastructure and fiscal credibility. A central bank can prevent an external shock from becoming an expectations shock. It cannot make the external shock smaller.
The expectation gap is narrower than the headline suggests. The ECB has already built an energy shock into its scenarios, and the September baseline still sees inflation declining from 3.0% in 2026 to 2.1% in 2028. The conventional view is not that the ECB can eliminate volatility. It is that the shock will fade without permanently dislodging expectations. The important question is whether another shock arrives before the previous one has passed through wages and services.
If repeated shocks arrive close together, the arithmetic changes. Businesses reset prices more frequently, workers negotiate from a higher starting point and households become less willing to treat inflation as temporary. The central bank then faces a more persistent process even if each individual shock remains outside its control. The second-order risk is not one war or one energy spike. It is the accumulation of shocks that shortens the distance between them.
The Counter-Case: Rates May Be the Only Credible Shield
The strongest counter-thesis is that the limits of monetary policy do not reduce its importance; they increase it. If the ECB responds too cautiously because the original shock is supply-driven, households and firms may infer that inflation above target will be tolerated. The result would be broader pass-through, higher wage demands and a longer period of elevated services inflation. In that scenario, higher rates are not supposed to prevent the war or repair supply chains. They are supposed to prevent the shock from becoming embedded.
The ECB’s own framework supports this concern. Its meeting account said the direct inflationary effect of the energy shock could become more persistent through indirect and second-round effects. It also said the Council would monitor how the shock fed into price and wage-setting, inflation expectations and overall economic dynamics. That is a central-bank argument for maintaining restrictive policy even when the original trigger is external.
The counter-thesis is especially strong because expectations can change before official data reveal a wage-price spiral. A household that expects energy prices to stay high may bring forward purchases. A firm may raise prices preemptively. A government may subsidize bills for longer than planned. Each decision is rational in isolation, but together they can make inflation more persistent. A credible rate path can coordinate those expectations in the opposite direction.
There is also a credibility asymmetry. If policymakers tighten and the shock fades, the economy may pay a temporary demand cost. If policymakers wait and expectations become unanchored, reversing that process may require a more severe tightening later. This is the strongest argument for acting before second-round effects are fully visible. The cost of an error is not necessarily symmetric across the two directions.
The answer is not to dismiss rates. It is to define their target correctly. Monetary policy should lean against second-round persistence, not promise to reverse the first-round shock. If underlying inflation remains contained, longer-term expectations stay anchored and wage growth moderates, additional tightening may impose more output damage than inflation benefit. If those indicators turn, the fact that the original shock was external is no defense against a policy response.
The falsifying signal for this article’s central judgment is a sustained break in the ECB’s own transmission indicators: inflation excluding energy and food rising above 3.0% year on year for three consecutive months, accompanied by longer-term inflation expectations moving materially above 2%. That combination would show that the shock had crossed from supply disturbance into a generalized inflation process. It would make higher rates more than a brake; they would become the main available shield. This is an analytical threshold, not an ECB forecast.
For now, the official evidence points the other way. In August, inflation excluding energy and food edged down to 2.4% from 2.5%, and the ECB said second-round effects had not yet appeared. Those data do not prove that the risk is gone. They show why the policy debate remains conditional rather than mechanical.
What the Limits Mean for Markets and the Economy
In the short term, the key variable is not simply the level of the ECB’s policy rate. It is the gap between energy-driven headline inflation and underlying inflation. A wider gap argues that the central bank is dealing with a supply disturbance; a narrowing gap would signal broader pass-through. That distinction can move rate expectations, sovereign yields and the euro in different directions.
In the medium term, rate-sensitive sectors face the cost of the response while energy-intensive and import-dependent sectors face the cost of the shock. Households with floating-rate debt feel tighter policy quickly. Manufacturers and transport companies feel higher input costs. Exporters may benefit from weaker domestic demand only if external demand holds up, while firms with pricing power are better placed to protect margins.
The distribution is not a simple risk-on or risk-off story. A credible ECB response can support longer-duration assets later by keeping expectations anchored, but a persistent energy shock can raise nominal yields even as growth slows. Sovereign spreads also depend on fiscal design: targeted support may stabilize incomes, while broad unfunded support can increase concerns about debt sustainability.
Financial intermediaries sit between the rate decision and the real economy. Banks may benefit from wider lending margins at first, but weaker borrowers and falling collateral values can raise credit risk. Insurers and pension funds may respond differently to higher nominal yields, while construction and other rate-sensitive industries face slower project pipelines. The same policy signal can therefore help one balance sheet and hurt another.
Over the long term, the structural question is whether the euro area reduces its exposure to shocks that monetary policy cannot address. That means energy infrastructure, diversified supply chains, labor mobility, productivity investment and fiscal rules that can absorb shocks without undermining confidence. The payoff would come through a lower frequency and smaller amplitude of inflation shocks, not through a particular ECB meeting.
The structural test is whether resilience investment changes the supply response before the next disruption arrives. More diversified energy procurement can reduce the pass-through from one commodity. Better infrastructure can shorten the time between a disruption and a substitute supply. More flexible labor and product markets can reduce the wage and margin response. None of these substitutes for a credible central bank, but together they reduce the number of times monetary policy must choose between inflation and output.
The ECB’s September baseline offers three practical scenarios. The base case is a gradual easing of the shock: inflation averages 3.0% in 2026, falls to 2.5% in 2027 and reaches 2.1% in 2028, while growth improves from 0.9% to 1.4% and then 1.5%. The upside case for activity requires energy pressure to fade, second-round effects to remain limited and financial conditions not to tighten further. The downside case is repeated energy or geopolitical disruption that lifts inflation excluding energy and food, weakens demand and forces a longer period of restrictive policy.
Short-term sentiment will follow the next energy and geopolitical headlines. Medium-term fundamentals will be decided by services inflation, wages and credit transmission. Long-term outcomes will depend on whether governments address the supply vulnerabilities Patsalides identified. Higher rates can buy time. They cannot manufacture resilience.
The ECB’s next decisions will therefore be read through a conditional lens: not “can rates stop the shock?” but “has the shock begun to reproduce itself inside the euro-area economy?” If inflation excluding energy and food remains near the August reading and expectations remain anchored, the case for patience strengthens. If it clears the 3.0% analytical threshold for three months and expectations move above 2%, the counter-thesis wins.
That is the boundary Patsalides’ warning draws. Monetary policy can stop a shock from becoming a regime, but it cannot stop the world from generating shocks. The euro area’s rate cycle may turn; its exposure to supply disruption will not turn by itself.
Higher rates can contain the aftershock, but only supply resilience can reduce the shock itself.
