Why Did Businesses Leave West Bengal?

There is a particular kind of tragedy embedded in the story of West Bengal’s economy, the tragedy of a civilization that once led the subcontinent, reduced over decades to a state of persistent underperformance and missed opportunity. During the Mughal and colonial periods, Bengal was among the most prosperous regions of the subcontinent. Despite the rapacity of the colonial administration, and despite partition, at independence, West Bengal was one of the most industrialised and developed states of India. Today, it is a shadow of that former self.

Once a powerhouse contributing 10.5 per cent to India’s gross domestic product (GDP) in 1960–61, West Bengal has witnessed a steady decline over the decades. By 2023–24, the state’s share had dwindled to just 5.6 per cent, a significant fall that reflects deeper economic challenges faced by the region. This is not merely a statistical footnote. It represents the erosion of livelihoods, the hollowing out of institutions, the flight of enterprise, and the slow suffocation of one of India’s most culturally and intellectually distinguished societies.

The story of this decline spans over six decades and several governments. It is a story shaped by colonial legacies, ideological choices, policy failures, political violence, governance dysfunction, and a culture that came to prioritise short-term patronage over long-term growth. Understanding it fully requires tracing the arc from India’s independence to the present day.

The Colonial Legacy and Partition

To understand West Bengal’s economic trajectory, one must begin before independence. Bengal under British rule was the commercial nerve centre of the empire in Asia. Kolkata (then Calcutta) was the first capital of British India and a hub of jute processing, tea trade, engineering, and finance. The Bengal Renaissance of the 19th century produced an extraordinary class of educated professionals, industrialists, and intellectuals who drove commerce and thought across the subcontinent.

But partition in 1947 dealt a catastrophic blow. The division of Bengal along religious lines severed the jute-growing hinterlands of East Bengal (which became East Pakistan, and later Bangladesh) from the processing mills concentrated in West Bengal. The jute industry, which had been the backbone of Bengal’s industrial economy, lost its raw material supply chain almost overnight. Millions of refugees poured across the border, straining the social and physical infrastructure of the state to breaking point. The demographic shock was immense, and it did not end in 1947. A second wave of refugees followed the 1971 Bangladesh Liberation War, once again placing enormous strain on land, employment, and public services.

While partition dealt a heavy blow to West Bengal, several other factors aggravated the state’s economic problems, including central and state policies. These impinged in areas of industrial and agricultural growth, urban development, and human development. The partition was, in a sense, the original wound. Everything that followed either helped the state recover or tore the wound wider.

The Central Government’s Role

A factor frequently underappreciated in popular discussions of Bengal’s decline is the role played by the central government’s industrial policy in the 1950s and 1960s. The freight equalisation policy introduced by New Delhi in 1956 had devastating consequences for West Bengal’s industrial competitiveness.

Under this policy, the central government subsidised the cost of transporting basic raw materials like coal, steel, and iron ore to make them equally available across India, regardless of geography. The stated goal was to promote industrial growth in underdeveloped regions. But the unintended consequence was to eliminate the natural locational advantage that West Bengal had long enjoyed by virtue of its proximity to the coal fields of Jharkhand and Bihar and the iron ore deposits of Odisha.

The Centre’s policy of freight equalisation gave a “major blow” to the engineering industry of the state. While the central government tried to protect the industries based on domestic market through import tariffs, it did very little to promote export-oriented industries like jute and tea, which were the traditional industries of West Bengal. Overnight, the competitive edge that had made Calcutta the workshop of eastern India was blunted. Industries that had no reason to locate elsewhere now had no particular reason to locate in Bengal either. New investments flowed to other states, Maharashtra, Gujarat, Tamil Nadu, while Bengal’s industrial base stagnated.

This structural handicap was compounded by chronic underinvestment by the centre in Bengal’s infrastructure during the early decades of planned development. The state’s political distance from New Delhi, particularly during the Congress-Left confrontations of the 1960s and 1970s, meant that it was often politically marginalised in the allocation of central funds, licenses, and public sector investments.

The Left Front Years (1977–2011)

No discussion of West Bengal’s economic decline is complete without a careful and honest assessment of the Left Front’s 34-year rule, the longest uninterrupted tenure of a democratically elected communist government anywhere in the world. This government, dominated by the Communist Party of India (Marxist), or CPI(M), came to power in 1977 on a wave of popular anger against the Congress government’s misrule and the Emergency.

The Left Front’s record is genuinely mixed. Its land reform programme, known as Operation Barga, redistributed land to millions of sharecroppers and gave them formal tenancy rights, improving agricultural productivity and rural welfare. West Bengal’s agricultural growth in the late 1970s and 1980s was impressive, and poverty in rural areas declined significantly. The Party built deep organisational roots across Bengal’s villages, creating a political infrastructure that was simultaneously a tool of governance and a mechanism of patronage.

But on the industrial and economic front, the record was far less impressive, and in many respects disastrous. The Left government was ideologically hostile to private capital, particularly large industrial capital. It encouraged militant trade unionism across the manufacturing sector, and politically affiliated unions routinely disrupted production, engaged in gheraos (illegal confinement of managers), and made the enforcement of labour discipline nearly impossible.

The main reason for the decline is a direct outcome of poor work culture, political interference, and failure of governance that has resulted in industrial anarchy that scares off private investment in the state. Factory closures accelerated through the 1980s and 1990s. The state’s share of total industrial output in India was 9.8% in 1980–81, declining to 5% by 1997–98. Established industries textiles, jute, engineering, chemicals, went into sustained decline. New industries simply did not come.

The rise of ultra-left Marxist urban militancy, hard-line labour unions and political instability led to capital flight, and eventually an all-round economic decline gradually weakened the state’s industrial base. Even after the liberalisation era transformed western and southern India, Bengal struggled to attract large-scale manufacturing investment.

When India liberalised its economy in 1991, states that had built investor-friendly reputations: Maharashtra, Gujarat, Andhra Pradesh, Karnataka, were positioned to attract the flood of new private and foreign investment. West Bengal was not. Its reputation for militant unionism, political interference in business, and erratic law and order kept investors at bay.

By the end of Left rule, fiscal stress had become acute. A 2011 CAG report highlighted that 76% of revenue expenditure was committed to salaries, pensions, and interest payments, leaving minimal room for capital investment. Capital expenditure stood at just 3.31% of total spending, far below the average for Indian states, indicating a systemic underinvestment in growth-enhancing infrastructure.

The fiscal position the Left Front bequeathed to its successor was a catastrophe. The state had borrowed heavily to finance current expenditures while investing almost nothing in productive infrastructure. The resulting debt burden would constrain every subsequent government.

Singur and Nandigram Fiasco

Ironically, it was under the later Left Front government of Buddhadeb Bhattacharjee that West Bengal made its most serious bid to attract modern industry, and it was the failure of this bid that sealed the state’s fate for years to come.

The Tata Motors project in Singur and the proposed chemical hub in Nandigram were two flagship investments that Bhattacharjee championed as part of an attempt to modernise the state’s industrial base. The land acquisition process for both projects became deeply controversial. Farmers and local communities resisted forcible acquisition, and the Trinamool Congress under Mamata Banerjee mobilised powerful political opposition to the projects.

High profile land conflicts in Singur and Nandigram during the 21st century deepened investor anxieties, while successive governments increasingly shifted towards welfare-driven politics rather than structural industrial expansion. In 2008, Tata Motors withdrew the Nano project from Singur, relocating it to Gujarat. The signal sent to the investor community was devastating. West Bengal’s investment image is still affected by past events, most notably the 2008 withdrawal of the Tata Nano project from Singur. No major industrial investor has forgotten this episode.

The Trinamool Congress Era (2011–2026)

When Mamata Banerjee swept to power in 2011, there was genuine optimism. After 34 years of Left Front stagnation, the change of government seemed to offer an opportunity to reset the state’s economic trajectory. The early promises were ambitious: industrial revival, improved governance, attracting investment, and reducing the state’s suffocating debt burden.

Some progress was made on the fiscal side. Since coming to power in 2011, the TMC has been trying to reverse the economic decline and strengthen the fiscal position but they remain a work in progress. In the wake of this reduction in the debt burden, the state’s interest payments declined from 58.77 to 46.64% of total own revenue between 2010–11 and 2022–23.

But the structural transformation that Bengal needed, a genuine reindustrialisation, a restoration of investor confidence, a reform of governance, never came. Instead, the TMC government became increasingly defined by populist welfare schemes, political patronage, and governance dysfunction.

West Bengal’s fiscal stress, which has deepened over the past 15 years, reflects a structural imbalance, a legacy debt trap compounded by persistent revenue deficits, low revenue buoyancy, and an expenditure shift towards committed and transfer payments under various populist welfare schemes, at the cost of growth-enhancing investment.

The Bengal Global Business Summits, held with much fanfare, produced billions of rupees in “investment commitments” that largely failed to materialise into actual projects on the ground. West Bengal ranks a poor 11th among states attracting FDI. West Bengal’s share of total national employment in manufacturing is 4% while its share of total Indian population is close to 8%, clearly indicating that the state severely underperforms in creating industrial jobs for its population.

The FDI figures are stark. From 2019 to 2025, the state secured only $663 million in FDI, a stark contrast to Maharashtra’s $26.2 billion. Over 2,200 companies also moved their headquarters or registered offices out of West Bengal between 2019 and 2024. These are not merely abstract numbers, they represent thousands of jobs that went elsewhere, tax revenues that were never collected, and opportunities that were forever lost.

The Debt Trap

At the heart of West Bengal’s economic dysfunction lies a severe and persistent fiscal crisis. The state’s total financial debt that stood at ₹1,918 billion as of 2011 swelled to ₹3,050 billion at the end of 2015–16 and is estimated to further grow to ₹6,932 billion at the end of 2024–25.

The state ranks fifth in terms of central debt of Rs 7.1 lakh crore, thanks to a heavy dose of populist schemes. This debt burden is not merely a balance sheet problem. It directly constrains the state’s ability to invest in roads, electricity, water, hospitals, schools, and industrial infrastructure, the very public goods that make a location attractive to investors and viable for workers.

Promising large social transfers has become a political football in India. It has become imperative for regional parties like the TMC to introduce their own versions of the dole. This welfare competition has meant that money that should have gone into productive infrastructure has instead gone into transfer payments that, while providing short-term relief to beneficiaries, do not generate the structural conditions for sustained growth.

The cumulative result of decades of underinvestment and industrial stagnation is visible most starkly in the per capita income data. A 2024 working paper by the Economic Advisory Council to the Prime Minister observed that West Bengal’s per capita income stood at 127.5 per cent of the national average in 1960–61. However, its growth failed to keep pace with national trends, leading to a decline in its relative per capita income to 83.7 per cent by 2023–24, now lower than even traditionally laggard states such as Rajasthan and Odisha.

This is a stunning reversal. A state that was wealthier than the national average by more than a quarter in 1960 is now significantly poorer than the national average. It has been overtaken not only by the obvious growth stories of Maharashtra, Gujarat, and Karnataka, but by states that were historically considered far less developed.

Brain Drain and Migration

Economic data captures only part of the human tragedy. West Bengal’s economic decline has been accompanied by a massive and sustained outflow of its most talented people. The perennial problem in Bengal has been the flight of human capital due to a lack of opportunities.

The collapse of credible job opportunities and declining confidence in higher education institutions created what many now openly call a brain drain. Parents who once believed Bengal would rise again began sending their children away not by choice but by compulsion. A generation that should have built Bengal chose to abandon it.

West Bengal possesses some of India’s finest educational institutions, including Jadavpur University, Presidency University, and the Indian Statistical Institute. But their graduates disproportionately leave the state in search of opportunities that do not exist at home. The talent that should be driving entrepreneurship, research, and institutional development in Bengal is instead contributing to the growth of Bengaluru, Hyderabad, Mumbai, and increasingly the cities of North America, Europe, and Southeast Asia.

The Structural Imbalance

The services sector accounts for nearly 55 percent of the state’s output, followed by industry at about 24 percent and agriculture at roughly 21 percent. This structure reflects not a natural evolution toward a service economy but rather the hollowing out of the manufacturing base. Industry’s share is well below what would be expected for a state of Bengal’s size, historical industrial heritage, and geographical advantages.

Agriculture, while still employing a large share of the workforce, is characterised by small landholdings, poor irrigation infrastructure in many areas, and vulnerability to both drought and flood. A significant portion of the workforce is engaged in informal, unpaid family businesses. The much-cited low unemployment rate masks the reality of widespread underemployment and disguised unemployment in low-productivity informal activities.

The Governance Deficit

Underlying all of the economic problems is a deep governance crisis. Successive governments have politicised state institutions, including the bureaucracy, the police, the panchayat system, and regulatory bodies. Political parties have used control of public institutions as a means of patronage distribution and social control rather than of service delivery and economic management.

The abrupt reversal of past incentive policies, some applied retroactively, has led to legal challenges and created reputational risks, signaling potential future regulatory uncertainty that deters long-term investment. When investors cannot trust that the rules will remain stable, they do not invest. This is perhaps the single most important reason why Bengal has failed to attract the private capital it needs.

Institutional architecture must move from populism to policy credibility. Single-window clearance systems must function in practice, not merely on paper. Governance must become data-driven, transparent, and accountable. These are the conditions that have been absent from West Bengal’s political economy for decades.

Conclusion

A decisive electoral mandate emerged from the West Bengal Assembly polls on 4 May 2026. The victory of the Bharatiya Janata Party (BJP) ends an era of 49 years of conflictual federalism. This political transition in West Bengal needs to translate into a structural economic reset, not merely incremental governance corrections. After decades of policy drift, institutional erosion, and missed industrial opportunities, the new dispensation has the chance to reposition Bengal within India’s growth story.

Whether any government can truly reverse the accumulated damage of more than six decades is the central question now facing the state. The ingredients for recovery exist, a large and skilled workforce, excellent port infrastructure at Kolkata and Haldia, proximity to the vast markets of eastern India and Bangladesh, and a surviving tradition of entrepreneurship and intellectual achievement. But recovery will require not just good intentions or new investment pledges, but a fundamental transformation of the political culture that has presided over Bengal’s long decline.
