The European Central Bank's Chief Economist, Philip Lane, has indicated that September will be a crucial moment for assessing and potentially adjusting the bank's monetary policy stance.

Speaking during a panel discussion in Donegal, Ireland, Lane stated that policymakers would calibrate interest rates by responding to incoming data. He noted that the Eurozone economy is primarily supported by domestic demand and argued that the United States is not a dominant force in global trade.

When asked how the ECB should address geopolitical challenges, Lane responded, "Our job is more about reacting." He added that the central bank's response would be "neither an overreaction nor an underreaction."

After raising rates in June, the ECB held them steady on Thursday to allow more time to assess the impact of heightened Middle East conflict on Eurozone inflation and economic growth. While officials have privately prepared for another rate increase in September, they have avoided making premature commitments in public statements.

Central bank governors from Germany, France, and Estonia pointed to last month's rate hike—the first since 2023—as a step toward returning inflation to the 2% target. They called for patience as the ECB awaits new information and forecasts. Austria's central bank governor noted that the choice in September would be between raising rates and holding them steady.

Lane declined to disclose his personal preference between the two options.

He said, "We will meet again at the beginning of September, so at every meeting, we will assess, adjust, and calibrate."

Lane described the current situation as a "medium-sized shock" and stated that much would depend on whether oil and gas prices remain elevated through September, or if a lasting solution can be found to restore supply through the Strait of Hormuz.

Reports released on Friday brought positive news on inflation and economic growth. A measure of private sector activity in the Eurozone rose to a five-month high, while an ECB survey showed a significant drop in consumer expectations for near-term price increases.

Meanwhile, oil prices retreated after hitting $100 per barrel, though this decline reflects renewed concerns about global economic growth following threats from US President Trump to impose new tariffs.

Lane did not appear particularly alarmed by this development. He argued that "trade between Europe and the United States is important, but it is not a dominant issue."

He added, "Europe trades with the whole world. The US is not the dominant factor in international trade."
