Record-low inflation continues to provide the central bank with room to cut further its key lending rate from the current level of 7.75 percent.
Within the goods component, food inflation eased to 0.7 percent from 1.1 percent in December; and prices of non-food products rose by 2.6 percent, softer than a 2.8 percent gain in the previous month. Also, cost of services went up by 3.9 percent after a 4.4 percent increase in December.
Annual core inflation rate also declined to an all-time low of 1.9 percent in January from 2.1 percent in the previous month.

Prices rose slower for food (0.5 percent from 0.6 percent in December) and services (0.1 percent from 0.3 percent) while non-food inflation was unchanged at 0.3 percent.
