ECB weighs December rate hike as policymakers assess inflation signals
ECB eyes December move

Euro zone monetary policy remains in focus after the European Central Bank keeps rates unchanged in November while officials leave open the possibility of another move next month. Christine Lagarde says incoming indicators will help determine whether a December increase is needed as energy costs pressure growth and prices.

Highlights

  • The ECB held its key deposit rate at 2.5% last week and will weigh incoming data to decide on a possible December hike.
  • Policymakers, including German and Italian central bank heads, signal a December rate hike is likely as energy costs elevate inflation risks.
  • Lagarde notes persistent energy-driven price pressures and rising AI-driven investment make the ECB’s December decision crucial for euro region outlook.

December decision hinges on incoming indicators

As reported by Reuters, the ECB is reviewing data points ahead of its December meeting after leaving its key deposit rate unchanged at 2.5% last week. Lagarde says policymakers will have many indicators between now and December to judge whether a further rate increase is necessary.

A long list of policymakers has already signalled that another move in December may be likely, including the influential heads of the German and Italian central banks. Lagarde, the ECB's outgoing president, is speaking at a financial literacy conference in Milan organised by Italy's Osservatorio for independent thinking.

She says the current environment is very hard, with energy costs bringing growth down while pushing prices up. Lagarde is also set to step down on February 7, 2027, months before the formal end of her mandate.

Energy pressures and AI shape euro zone outlook

Lagarde says it is difficult to separate supply-driven shocks from demand-driven ones, underscoring the need for caution in how the ECB uses interest rates. At the same time, she says policymakers must act to prevent inflation expectations from running away and to stop price pressures from spreading through the broader economy.

She also points to artificial intelligence as a force that is fuelling investment demand and helping make the euro zone economy more resilient. That mix of persistent price risks and pockets of support for activity keeps the ECB's December decision central to the region's financial and business outlook.

Draghi’s warning on the debt–inflation trade-off in a higher-rate environment highlighted how keeping interest rates above growth for too long can worsen public debt dynamics and raise pressure for “fiscal dominance.” Our publication previously noted his argument that central banks should prioritize inflation control while keeping rates no higher than necessary to preserve productive investment, alongside calls for EU-level measures to support AI-related investment and long-term resilience.
