London, Sept. 18 (BridgeNews) - U.K. inflation rose in August to come in above the Bank of England Monetary Policy Committee's target. The key RPIX measure, retail prices excluding mortgage interest payments, came in at up 0.4% on the month and up 2.6% on the year, just above the MPC's 2.5% aim. One key factor behind the rise was the increase in seasonal food prices, which were up 10.0% on the year.
In August, RPIX hit its highest level since March 1999. However, the rate for all retail prices was a more subdued 2.1% on the year, although this too rose 0.4% on the month.
Aside from seasonal food, other upward effects on the RPI index came from motoring expenditure, up 0.4% on the year, and fuel and light, up 2.3% on the year.
The Office for National Statistics painted a mixed picture of inflation pressures in coming months.
