The European Central Bank left its benchmark interest rate unchanged at 2.25% on Thursday, pausing after a quarter-point hike in June, as it assesses how volatile energy prices will affect inflation. The decision affects the 21 countries that use the euro currency. The bank said uncertainty remains high and the full inflationary impact of the energy shock has yet to play out, adding that it remains well positioned to navigate the uncertainty caused by the conflict. Inflation in the eurozone ran at an annual 2.8% in June, down from 3.2% in May. Analysts suggest the bank may be gathering more information amid oil price swings, with the next meeting on September 10 seen as a possibility for another rate increase.
