Latin American nations such as Colombia have been raising interest rates to fight inflation after having cut them to battle fallout from the global economic crisis.
Inflation expectations for 2011 rose to 3.21 percent versus 3.10 percent in the last poll, while those for 2012 increased slightly to 3.38 percent compared with 3.31 percent previously, according to the survey.
In May, consumer prices rose 0.28 percent, above market expectations due to a surge in food prices.
The central bank has an inflation target of between 2 percent and 4 percent for this year and expects the economy to grow between 4 percent and 6 percent in 2011.
