India's Capex Puzzle: Public Spending Drives Growth as Private Sector Pivots

Introduction: The Capex Conundrum

For India to achieve its ambitions of rapid industrialization and mass employment, private capital expenditure (capex) is the designated engine of growth. When businesses invest in factories, machinery, and technology, they create a virtuous cycle of jobs, income, and demand. However, for the better part of a decade, this engine has sputtered. Despite strong headline economic growth, private capex has stubbornly refused to accelerate, a situation often described as a “private capex crisis.” Its share in the economy has steadily declined, forcing the public sector to take on the heavy lifting. Yet, beneath the surface of this long-standing issue, the dynamics are shifting. While a broad-based boom remains elusive, a combination of massive government spending and a targeted revival in new-age sectors suggests the private capex story may be closer to a turning point than a continued decline.

The Government as the Primary Growth Engine

In the absence of robust private investment, the Indian government has stepped in decisively to prevent the economy from stalling. Public investment, through both direct government spending and state-owned enterprises, has reached multi-year highs, accounting for approximately 8.4% of GDP in 2023-24. This strategy is set to continue, with the government's capital expenditure budget estimated to rise from ₹11 trillion to ₹12.2 trillion. This sustained push into roads, railways, ports, and digital networks serves a dual purpose: it creates immediate demand for core materials like steel and cement while building the foundational infrastructure intended to “crowd in” private investment by lowering logistics costs and improving productivity. Central government capex surged by a remarkable 40% year-on-year in the first half of FY26, with states also contributing significantly, their aggregate capex rising 13% in the same period.

A Decade of Private Sector Caution

The private sector's current hesitancy is rooted in the painful aftermath of the last major capex boom, which ended in the early 2010s. That cycle, fueled by over-optimistic demand projections and excessive debt, left many corporations with stressed balance sheets and banks with a mountain of non-performing assets. The subsequent decade was spent on a painful but necessary clean-up. This experience has instilled a deep sense of caution in corporate India. As a result, private capex has remained stuck at around 12% of GDP for over ten years, and its share of total investment (Gross Fixed Capital Formation) fell to a low of 34.4% in 2023-24. While corporate balance sheets are much healthier today, the memory of the past has made businesses selective and cautious about committing to large, long-term projects.

Glimmers of a Private Sector Revival

Despite the overarching caution, there are clear signs that the private sector is beginning to spend again. Bellwether institutions like the State Bank of India (SBI) have reported a strong corporate credit pipeline of ₹7 trillion, noting that demand for new projects is now broad-based and predominantly private. Similarly, Larsen & Toubro (L&T) has pointed to a turnaround in domestic orders. Aggregate data supports this view. A sample of nearly 1,900 listed non-financial companies saw their capex grow by 11% to ₹9.4 trillion in FY25. Furthermore, new investment announcements climbed 15% year-on-year to ₹15.1 trillion in the first half of FY26, with the private sector impressively accounting for 88% of this value. This indicates that while execution may still be led by the public sector, the intent to invest is strengthening significantly within private enterprise.

A New Kind of Capex Cycle

Crucially, the emerging private capex revival looks very different from its predecessors. It is not a broad-based surge across all sectors but a concentrated push into specific, often technology-driven, areas. Economists note that manufacturing is clearly driving the upturn, while services-led capex remains weak. Within manufacturing, the momentum is in new-age industries. Metals, driven by global demand and new applications in EVs and AI, accounted for 28% of private capex announcements in H1 FY26. Other leading sectors include renewables, electronics manufacturing under the Production-Linked Incentive (PLI) scheme, data centers, and chemicals. In contrast, traditional large-scale infrastructure projects led by private players remain limited. This sectoral pivot signifies a structural shift from a debt-fueled, commodity-heavy cycle to one led by technology, sustainability, and advanced manufacturing.

Market Impact and Future Outlook

The current landscape presents a nuanced picture for investors. The old playbook of betting on “everything infrastructure” has given way to a more thematic approach focused on execution leaders in policy-aligned sectors. The government's continued focus on railways, defence, and urban infrastructure provides a stable demand floor. However, the high-growth opportunities are increasingly found in power transmission and distribution, grid modernization, defence electronics, and digital infrastructure like data centers. The surge in bank sanctions to the power sector, which now accounts for 40% of the total, underscores the focus on energy security and the green transition. While valuations in the capital goods sector are rich, the robust order books and improving corporate health suggest a sustainable, albeit more concentrated, growth cycle ahead.

Conclusion: A Tale of Two Engines

India's capex story is one of transition. The public sector engine is firing on all cylinders, providing the necessary thrust to keep the economy moving forward. Simultaneously, the private sector engine is gradually restarting, not with a roar but with a targeted hum in the sectors of the future. The challenge lies in ensuring the momentum from public spending translates into a broader, self-sustaining private investment cycle. If domestic demand remains steady and policy execution remains certain, the foundation being laid today could launch India into its most significant multi-year expansion since the early 2000s, this time on a more diversified and technologically advanced footing.
