Headline inflation accelerated to a seven-month high of 6.46% in September, mainly driven by higher food prices, government data showed on Monday.
Wholesale prices, India's main inflation measure, had risen 6.1% in August.
Expert views:
BADRISH KULHALLI, FIXED INCOME FUND MANAGER, HDFC STANDARD LIFE INSURANCE CO
"There seems to be some amount of the currency weakness being passed on to prices, especially primary article prices. We haven't seen any improvements in prices because of the good monsoon. probably we'll have to wait until November and December in time for the harvest season to see any impact on food prices.
"This will not give much comfort for RBI to hold rates and sets up for a rate hike in the upcoming policy review at the end of the month."

"Headline inflation has risen to 6.46% in September on account of joint impact of food inflation and rupee depreciation.
"Rising input costs have again pushed up core inflation on a month-on-month basis. We have to wait and see how better harvest this year pushes down the food inflation despite pressures from the political economy. While CAD worries have faded, inflation continues to remain the major macro risk".
DHARMAKIRTI JOSHI, CHIEF ECONOMIST, CRISIL LTD, MUMBAI:
"The non-core inflation is pressurising and it cannot be ignored by the central bank. And we believe another 25 basis points rate hike is coming because expectation on inflation still continue to remain high.
"Monsoon impact is yet to play out, and if the monsoon rains put some downward pressure on food, but food will not be completely tamed though. Looks like at least one more rate hike after October is likely.
R K GUPTA, MANAGING DIRECTOR, TAURUS MUTUAL FUND, DELHI
"Inflation is not materially high as government had increased gas, petrol and diesel prices last month. Even vegetable prices are high especially in North India because of heavy rains.
"It is on expected terms. Only fear is with higher WPI rate, the Reserve Bank of India may consider raising rates further.
"I don't think inflation will come down because every month government is raising prices of one product or the other."
ABHEEK BARUA, CHIEF ECONOMIST, HDFC BANK, NEW DELHI:
"The bottom line is that with the new governor it's very clear he will not unnecessarily over-react to just one month's print.
"I think the RBI is forward looking and they are looking at the medium-term inflation trajectory as it's likely to pan out instead of getting excessively influenced by this one print.
"Having said that, there was a case for a repo rate hike, which the governor had sort of pointed to, in the next policy. And, I think this data sort of strengthens the case for keeping things a little tight as far as monetary policy is concerned.
"We will see a substantial pick up from December because of the base effect. So the numbers are not going to look any better going forward.
"I think what we are trying to arrive at, is a situation where the rate level is compatible with both the inflation situation and the growth situation on the ground. I think 7.75-8% repo rate, that should be consistent with both the growth situation and the inflation pressures."
A. PRASANNA, ECONOMIST, ICICI SECURITIES, PRIMARY DEALERSHIP LTD, MUMBAI:
"Ideally, one number should not change expectation. There was anyway a case for a rate hike based on the previous inflation prints, including the CPI. This number has reinforced the case for a 25 basis points repo rate hike by the RBI."
RADHIKA RAO, ECONOMIST, DBS, SINGAPORE:
"WPI inflation continues to accelerate on higher primary index and release of suppressed prices - especially as certain product categories punch above their weight.
"Looking ahead, as base effects wear-off, headline prints could move another leg higher October onwards. Focus shifts to the CPI next, amidst increasing indications that the RBI might align the benchmark policy decisions to the retail gauge.
"This being the case, there is headroom for the repo rate to be adjusted higher in the coming months. These concerns are reflected in the kneejerk negativity in the market."
DEVEN CHOKSEY, MANAGING DIRECTOR, K R CHOKSEY SECURITIES LTD, MUMBAI
"Inflation numbers are a complete letdown. I think food and fuel have killed the numbers. Markets are disappointed as traders have been expecting the Reserve Bank of India to go on a rate reduction program, and that is where a low inflation would have helped."
