NEW DELHI (REUTERS) - India regained its status as the world's fastest-growing major economy in the October-December quarter, surpassing China for the first time in a year as government spending, manufacturing and services all picked up.

Asia's third-largest economy grew 7.2 per cent in the December quarter, its fastest in five quarters, Ministry of Statistics data showed on Wednesday (Feb 28). That beat China's 6.8 per cent and a forecast of 6.9 per cent by analysts polled by Reuters.

In a data set that some economists said had put an early interest rate hike on the agenda, India also edged up its 2017/18 GDP growth forecast to 6.6 per cent from 6.5 per cent.

India's manufacturers and service industries have been struggling to overcome disruptions from the bumpy launch of a national sales tax in July.

In the December quarter, annual growth in the manufacturing sector however climbed to 8.1 per cent from 6.9 per cent in the previous quarter, while financial and other services grew at 7.2 per cent from 5.6 per cent.

"Settling down of Goods and Services Tax (GST) reforms will boost growth in the next fiscal year," said Anita Gandhi, a director at Arihant Capital Markets.

Some economists now anticipate the Reserve Bank of India (RBI), which is trying to balance concern over inflation with support for growth, could raise interest rates after its next policy meeting on April 5.

"We expect a rate hike from RBI, most likely at the August review," said Abhishek Upadhyay, economist, ICICI Securities Prime Dealership, citing inflationary pressures.

The central bank has kept its key rate unchanged since a 25 basis points cut in August. Retail inflation eased marginally to 5.1 per cent in January from a 17-month high of 5.2 per cent in December.

Urjit Patel, RBI governor, this month said the economic recovery was at a nascent stage and called for a cautious approach.

BAD LOANS AND JOB CREATION

Wednesday's data is likely to be welcomed by Prime Minister Narendra Modi.

Last week, he told industrialists that his government was determined to put the economy back on a higher growth trajectory, but it is still far from firing on all cylinders.

Modi faces criticism over mounting bad loans at state banks and a US$1.77-billion (S$2.3 billion) fraud at state lender Punjab National Bank , the biggest in the country's banking history.

Meanwhile, he is trying to accelerate growth through higher state spending, including 2.1 trillion rupees (S$43 billion) for the recapitalisation of state banks, which are beset with mounting bad loans of nearly US$148 billion.

He has stepped up spending on infrastructure and welfare projects to boost growth ahead of national elections in 2019.

This has widened the fiscal deficit for the year ending in March, to 3.5 per cent of GDP from the 3.2 per cent projected earlier.

Creating jobs for near one million youth entering the market every month has been a key challenge, and he raised import tax on near 50 items this month to support domestic manufacturers.

In November, Moody's raised India's investment grade rating one notch, the agency's first upgrade in nearly 14 years, but cautioned against macroeconomic risks.

India grew at more than 9 per cent a year from 2005 through 2008.

Higher oil prices and increased pressure on market borrowings from government have already increased bond yields and this is likely to hit private investment and growth further.

Growth in factory activity slowed to a four-month low in February as new orders eased and weighed on output after manufacturers raised prices at the fastest pace in a year, a private business survey showed on Wednesday.

Analysts said bad loans in banks and inflationary risks arising from high food and crude prices pose risks to growth.

"There are concerns of a rising fiscal deficit and the possibility of interest rates rising further," Gandhi said.
