India's services sector grew at its fastest pace in five months in December riding on a surge in new business and expansion in employment, but rising input prices will likely add to inflationary pressures in the coming months, a survey showed.
The HSBC Markit Business Activity Index -- based on a survey of around 400 firms -- rose to 54.2 in December from 53.2 in November, staying above the 50 mark that separates growth from contraction for the second month in a row.
The index had contracted to levels below 50 in September and sunk to a two-and-a-half year low of 49.1 in October.
In the December survey, the new business sub-index jumped to 55.7 from 52.3 in November, thanks to an improvement in demand.
"Activity in the services sector picked up pace in December led by faster growth in new business, underscoring the resilience of the sector," said Leif Eskesen, economist at HSBC.
Both the services PMI index and the new business sub-index were at their highest levels since July.
