Irish annual inflation rose to its highest level since 2007 last month, with prices jumping by 5.1% compared to 3.7% in September after sharp increases in transport and energy costs, Central Statistics Office data showed on Thursday. Rises of 15.4% in transport and 10.8% in electricity, gas, water and other fuel costs represented the largest year-on-year increases. Overall prices were 0.7% higher month-on-month, the fastest monthly rise in seven months. The finance ministry forecast last month that inflation will peak at average 4.5% in the final quarter before falling below 2% next year. However, it said the rate could be closer to 3.5% during 2022 if there were higher energy prices, prolonged global supply chain disruptions and greater short-term economic demand.
