CPI annual inflation stands at 3.0 per cent in April 2012, down from 3.5 per cent in March. The timing of Easter had a significant impact on the April data. Air transport, off-sales of alcohol, clothing and sea transport were the most significant drivers behind the decrease in annual inflation between March and April. Partially offsetting these were smaller upward pressures from the operation of personal transport equipment, restaurants & hotels and rents. The CPI stands at 122.9 in April 2012 based on 2005=100.
RPI annual inflation stands at 3.5 per cent in April 2012, down from 3.6 per cent in March. The largest downward pressures to this change came from alcoholic drinks, clothing, fares & other travel and the purchase of motor vehicles. Partially offsetting these were upward pressures from housing and petrol & oil. The RPI stands at 242.5 in April 2012 based on January 1987=100.
