BEIJING (AFP) - China said Saturday that inflation topped five percent for the first time in more than two years, a figure analysts said would lead to fresh interest rate hikes as officials battle to curb rising prices. The countrys consumer price index rose a faster-than-expected 5.1 percent year-on-year in November as food costs continued to soar, compared with 4.4 percent in October, the National Bureau of Statistics (NBS) said. It was the fastest increase in consumer prices since July 2008, when inflation hit 6.3 percent, and was well above the governments full-year target for three percent. Analysts had forecast inflation would be 4.7 percent on year, according to Dow Jones Newswires. Price rises in November are beyond many peoples expectations indeed, said NBS spokesman Sheng Laiyun. It will take some time for the policies (on curbing price rises) to be implemented and show clear effects. Ever fearful of inflations historical potential to spark unrest in China, Beijing has ordered a range of steps to boost supplies of key goods after severe summer flooding and recent cold snaps hit yields and drove up prices. As part of these efforts, the central bank announced in October the countrys first interest rate hike in nearly three years. On Friday, the central bank ordered lenders for the sixth time this year to keep more money in reserve as authorities struggle to stem the flood of liquidity into the economy, which is fanning the inflation problem. Royal Bank of Canada analyst Brian Jackson said the inflation figure showed Beijing needed to bring out the big guns such as further interest rate hikes, with an increase in benchmark rates any time now. He predicted China would raise benchmark rates by 25 basis points before year-end with rates rising a further 75 basis points over the next year. While food costs remained the major driver of inflation last month up 11.7 percent on year non-food prices also gathered pace, rising 1.9 percent year-on-year compared with Octobers 1.6 percent increase. It is slightly alarming that there is price pressure outside of food, said Tom Orlik, a Beijing-based analyst with Stone & McCarthy Research Associates. I dont think we are going to see rampant inflation but I think 5.1 percent is certainly enough to have the government accelerate its efforts to contain the problem. There had been mounting speculation that an interest rate hike or tighter lending restrictions were imminent after Beijing pledged last week to shift its monetary policy stance to prudent from relatively loose next year. Analysts have said November could mark the peak for inflation, citing official figures that show food costs eased in recent weeks after the prices of key vegetables soared more than 60pcin early November. Chinas economic planner, the National Development and Reform Commission, said in a statement it expected CPI growth to slow to less than five percent as moves to control grain, vegetable and cooking oil prices take effect. Economists have blamed the governments 586-billion-dollar stimulus package unveiled in late 2008 in the wake of the global financial crisis and rampant lending last year for driving up prices. Other key data showed industrial output from Chinas factories rose 13.3 percent on year, up from 13.1 percent in October, even as Beijing closed highly polluting operators and rationed power to energy-intensive industries. Factories have been getting around the power restrictions by using diesel generators to keep assembly lines churning out goods, leading to a nationwide shortage of the fuel. Fixed asset investment in urban areas, a measure of government spending on infrastructure, rose 24.9 percent over the January-November period, slightly faster than the 24.4 percent over the first 10 months of the year. Retail sales, a key measure of consumer spending, jumped 18.7 percent on year compared with 18.6 percent in October.
