NOIDA, India, Aug 26 (Reuters) - After a decade labouring on building sites around New Delhi, Akhilesh Kumar lost his scaffolding job last month when his employer halted work on an array of 30 residential towers.
He joins more than half a million workers let go from sites around India’s capital in the last 18 months, in a stark sign that the reality in Asia’s third-largest economy is far from as rosy as official data suggests.
The deepening downturn in the building sector makes it easily understandable why Prime Minister Narendra Modi’s image as the country’s economic saviour has lost its lustre just over a year after his resounding election victory.
“If I don’t get another job, I have no other choice but to go back to my village and work as a farm labourer,” said Kumar, who is in his twenties.
The decade-long construction boom in cities like Noida, where Kumar earned $165 a month, lured millions of labourers from rural hinterlands, creating one in every three new jobs.
That process is going into reverse, undermining Modi’s promise to create more employment for the one million Indians who join the workforce every month.
Indebted developers are cutting staff as they slow work on existing projects and postpone new ones until they clear a backlog of 700,000 unsold homes.
A law to clamp down on “black money” flows that fund as much as a third of real estate deals is further squeezing demand.
Across India, housing starts fell 40 percent in the first half of the year, consultancy Knight Frank said. Cement output grew 0.9 percent between April and June, down from 9.6 percent a year earlier when Modi took office, government data show.
“The slowdown in the construction sector is very, very depressing which will have a negative impact on the overall GDP growth numbers,” said Samantak Das, chief economist at Knight Frank India.
Rating agency Moody’s last week cut India’s growth forecast to 7 percent for this fiscal year, against the government’s target of 8 to 8.5 percent.
India releases its gross domestic product figures for the April-June quarter on Monday.
The lack of jobs is already felt in the northern state of Bihar, source of many of the labourers toiling near Delhi.
In Patna, the state capital, eight out of 20 labourers contacted by Reuters had this year made the 1,000 km (600 mile) trip back from Delhi because they could not find work - pressuring salaries in a region where wages are already low.
According to brokerage Ambit Capital, rural wages may now be falling after growing 4 percent in the year to March - a far cry from the double-digit annual rises between 2010 and 2014.
“Labourers are starving and are ready to work even at lower wages as there are fewer or just no jobs,” said Navendu Kumar Thakur of the Builders Association of India.
The squeeze comes at a bad time for Modi.
Bihar heads to the polls this year, in an election his Hindu nationalist Bharatiya Janata Party must win to gain seats in the upper house of parliament where he lacks a majority to pass economic reforms.
Economists say that lower interest rates and a government splurge on infrastructure should help revive construction, which contributes a tenth of GDP.
Modi’s party also wants to regulate property markets and tie investor money to specific projects to stop developers diverting cash.
But the slowdown around Delhi, where unsold inventory is highest, shows no sign of ending.
Noida, a city of 640,000, has grown rapidly in the last decade, expanding to a point where its middle-class housing complexes meld with Delhi’s urban sprawl on one side and villages on the other.
Around the site where Kumar worked, half-built high-rises dot the skyline. Cranes and diggers stand idle. His former employer, The 3C Company, has cut staff on the 3,000-unit “Lotus Boulevard” by more than half, employing some elsewhere.
Sales staff at two sites reported a 30 to 50 percent decline in bookings in the last year.
Real estate association CREDAI’s Rohit Raj Modi estimates more than a million labourers worked in construction at Noida at its peak in 2013, at least double today’s number.
Even when the market recovers, a shift to mechanisation on larger sites would limit demand for workers.
“From a labour point of view, the peak is over,” he said. (Additional reporting by Manoj Chaurasia in Patna; Editing by Douglas Busvine and Simon Cameron-Moore)
