NEW DELHI (Reuters) - Rising food prices pushed India's retail inflation to a 17-month high in December, breaching the central bank's medium-term target for the second straight month, which could intensify pressure for it to raise policy rates in the next few months.
India's measure of consumer price inflation, the CPI index, rose 5.21 percent in December from a year earlier, the Ministry of Statistics said on Friday.
Analysts polled by Reuters had predicted December's consumer inflation rate would climb to 5.10 percent, the highest since July 2016, from 4.88 percent in November.
Annual retail food inflation rose 4.96 percent in December from 4.35 percent in the previous month.
The Reserve Bank of India held its policy rate steady at 6.0 percent last month and said all possibilities were on the table, depending on how price pressures and growth panned out.

Sunil Sinha, principal economist at India Ratings, said the RBI was unlikely to change its policy stance soon.

Rising inflation amid firm global crude oil prices is a major worry for Prime Minister Narendra Modi ahead of his last full-year budget, due on Feb. 1, as he hopes to win a second term in 2019.
Analysts said any sharp rise in state spending in the budget that fuels inflation could force the central bank to raise rates earlier than expected.
The U.S. central bank is forecasting three rate hikes for 2018. It raised rates three times last year.
