According to online reports, three sources said that ECB policymakers believe that the December meeting is the most realistic time frame for discussing whether another interest rate cut is needed to cushion the impact of U.S. tariffs on the euro zone economy. The European Central Bank left interest rates unchanged on Thursday and maintained an optimistic view of economic growth and inflation, curbing expectations of further interest rate cuts. But ECB Governing Council sources said the debate on interest rate cuts is not over yet, but policymakers may not be able to obtain enough information to make a proper assessment before their next meeting on October 29. That means that given upcoming inflation and economic growth data and the next batch of forecasts, the December 18 meeting is seen as a more likely date to discuss reducing borrowing costs.
