NEW DELHI Indian data due out on Friday is expected to show inflation accelerated in November because of a weak rupee and festive consumer demand, dampening any lingering hopes of a central bank rate cut next week to boost the stuttering economy.
A Reuters poll forecast the wholesale price index, India's main inflation measure, rose an annual 7.6 percent in November, up from 7.45 percent in October.
The government will release the data at 0630 GMT.
Asia's third largest economy is headed for the weakest full-year growth in a decade, at about 6 percent, far below the near double-digit pace before the global economic downturn.
But despite the slowdown, the Reserve Bank of India (RBI) has not lowered interest rates since April because inflation has remained near seven percent, exacerbated by a weak rupee that has added to the cost of fuel imports.
"We expect that repo rate would be held in next week's policy. Inflation is likely to remain around 7.6 percent for the full year, though there may be some easing in the fourth quarter," said Adity Nayar, an economist at rating agency ICRA.
The bank has said any interest rate cut is "highly improbable" at the next policy meeting on Dec 18.
That stance was supported by data released earlier this week showing that October industrial output unexpectedly leapt to 8.2 percent growth after contracting the previous month.
Some economists do predict a cut in the cash reserve ratio (CRR), the deposits that banks keep with the central bank, to help liquidity, possibly followed by a rate cut in January.
Data on Wednesday showed that retail inflation, a relatively new index less closely watched than WPI, moved to near double-digits in November driven by a spike in food prices.
Diwali and other religious festivals in November are traditionally a period of high consumption, which can push prices higher.

The inflation data also reflects pressure on fuel prices, resulting from the rupee's 1 percent depreciation in November. India imports 80 percent of its oil needs, and the crude oil import bill rose 16.8 percent in November from a year ago to $14.5 billion, despite lower global prices.
India's chief economic advisor Raghuram Rajan cautioned against reading too much into the spike in industrial output numbers, which partly reflected statistical differences due to the timing of the festival season.
"Clearly, we should not be overly influenced by one number," Rajan said. "We should take it as part of a pattern. That hopefully, economic growth is stabilizing, and that we have to wait and see whether it starts strengthening."
Other bright spots include an uptick in investment in recent months and a surge in infrastructure output.
But the fiscal deficit, like inflation, remains the highest among the BRIC group of emerging economies, that also includes Brazil, China and Russia.
Rating agency Standard & Poor's warned again on Tuesday that India's credit rating faces a one-in-three chance of being downgraded to junk over next 24 months because of a heavy debt burden and the fiscal deficit, which is seen overshooting a target of 5.3 percent in the fiscal year ending in March.
Hurt by a slow global recovery and uncertainty in the euro zone, India's exports have slumped this year, contracting 6 percent during the April-November period.
Economists say any recovery is likely to add to inflationary pressures in the short term as capacity becomes stretched by domestic demand for consumer goods, housing, and rising capital investment by industry.
Finance Minister P Chidambaram is banking on small policy steps including selling stakes in state-owned companies to attract capital inflows that could strengthen Indian rupee and help bringing down inflation. In the longer term, the government is trying to end supply bottlenecks by upgrading infrastructure.
