Indonesia's economic growth accelerated to 6.9 percent in the fourth quarter of last year, adding to expectations for more interest rate hikes.

Rusman Heriawan, head of the Central Statistic Bureau, said Monday that the expansion in the October-December quarter brought growth for all of 2010 to 6.1 percent.

He said growth last year came from all sectors of Southeast Asia's largest economy, including a 13.5 percent expansion in transportation and communications. Agriculture lagged, growing 2.9 percent.

Last week, the country's central bank raised its benchmark interest rate by a quarter percentage point to 6.75 percent, after holding it at a record low of 6.5 percent for the previous 18 months, to dampen inflation.
