Why in News?
In January 2026, the United States announced its withdrawal from 66 international organisations, citing a reassessment of national interests. Among the climate-related bodies affected is the International Solar Alliance (ISA)—a global platform headquartered in India and jointly led by India and France. The move has raised questions about its economic, industrial, and geopolitical implications, particularly for India and developing countries.
What is the International Solar Alliance?
The ISA was established in 2015 on the sidelines of the Paris Climate Conference (COP21) with the objective of promoting solar energy adoption, especially in countries located between the Tropic of Cancer and the Tropic of Capricorn.
Headquartered in Gurugram, India, the Alliance does not directly construct solar power plants. Instead, it plays a facilitating role by:
- Mobilising low-cost finance
- Reducing investment risks
- Supporting capacity building and training
- Accelerating deployment of solar technologies
The ISA currently has over 120 member countries, with a strong focus on Africa, Small Island Developing States, and other climate-vulnerable regions. The U.S. joined the Alliance relatively late, in 2021, and contributed about $2.1 million over three years, a small fraction of ISA’s total funding.
Will the U.S. exit financially weaken the ISA?
From a purely financial perspective, the impact is expected to be limited. U.S. contributions accounted for roughly 1% of the Alliance’s total funds. Indian officials have clarified that:
- Ongoing programmes will continue uninterrupted
- Training and capacity-building initiatives remain intact
- Day-to-day functioning of the ISA is not at risk
However, the concern lies less in budgets and more in global confidence and signalling. When a major economy steps away from climate platforms, it can create uncertainty among lenders and investors, particularly in high-risk developing markets.
What does this mean for India’s solar manufacturing capacity?
India’s solar sector remains largely insulated from the U.S. decision. India does not depend on the U.S. for critical solar equipment. Instead, it has rapidly expanded domestic manufacturing under policy support such as Production-Linked Incentives (PLI).
As of late 2025:
- Solar module manufacturing capacity stood at nearly 144 GW
- Solar cell manufacturing capacity was about 25 GW, with rapid expansion underway
China continues to dominate global production, accounting for nearly 70% of global solar cell manufacturing capacity. India imported about $1.7 billion worth of photovoltaic modules from China in FY25, according to Parliamentary data from the Ministry of New and Renewable Energy.
Crucially, the U.S. exit does not raise project costs, affect electricity tariffs, or disrupt India’s solar supply chains.
Will solar investments in India slow down?
A slowdown is unlikely. India’s solar investments are driven primarily by:
- Strong domestic electricity demand
- Long-term power purchase agreements with state utilities
- Policy continuity and market scale
Funding for Indian solar projects mainly comes from domestic banks, global institutional investors, and multilateral development agencies, not the U.S. government. Employment in the solar sector—spanning manufacturing, installation, and operations—is also largely domestically anchored.
In fact, there could be a potential upside. As the U.S. becomes more inward-looking and faces supply-chain frictions with China and Mexico, Indian firms may find opportunities to:
- Export solar equipment
- Set up manufacturing units aligned with U.S. technical standards
Much will depend on the trajectory of India–U.S. trade negotiations.
Where does the real economic risk lie?
The most significant impact is likely to be felt outside India, particularly in:
- African nations
- Small and poorer developing economies
These regions rely heavily on concessional finance, multilateral cooperation, and risk-sharing mechanisms to deploy solar projects. Reduced climate engagement by large economies like the U.S. can:
- Make lenders more cautious
- Delay project approvals
- Increase financing costs
This could indirectly affect Indian solar companies expanding abroad, as the ISA has been a key platform for opening overseas markets.
Why does this matter for India’s global role?
The ISA is a cornerstone of India’s climate diplomacy and Global South leadership. It strengthens India’s:
- Soft power
- South–South cooperation credentials
- Economic presence in emerging markets
While the U.S. exit removes one influential partner and some technical expertise, it does not alter leadership within the Alliance. India remains at the centre of the ISA, but with greater responsibility to sustain momentum and confidence.
What lies ahead?
For India:
- Solar power does not become costlier
- Domestic projects and jobs remain secure
- Manufacturing capacity continues to expand
The broader challenge is a more fragmented global climate order, where cooperation is harder and emerging economies must work harder to attract finance.
For India’s solar ecosystem, the U.S. exit is not a shock, but a stress test—and compared to a decade ago, India appears far better equipped to handle it.

Answer: A
Explanation
- Statement 1 – Correct
The International Solar Alliance (ISA) was launched in 2015 on the sidelines of the UN Climate Change Conference (COP21) in Paris by India and France. - Statement 2 – Incorrect
Initially, ISA membership was open only to countries located fully or partly between the Tropics of Cancer and Capricorn (torrid zone).
Although in 2018 membership was opened to all UN member states, not all UN members are ISA members in practice.
CARE MCQ
Consider the following statements about the International Solar Alliance (ISA):
- ISA was jointly launched by India and France to promote solar energy.
- Since 2020, all UN member states are eligible to join ISA.
- ISA targets mobilising $1 trillion for solar energy by 2030.
How many of the above statements are correct?
- Only one
- Only two
- All three
- None
Answer: C
Explanation:
- Statement 1 – Correct:
The ISA is a joint initiative of India and France, conceptualized on the sidelines of COP21 (Paris, 2015) to combat climate change through solar energy deployment. - Statement 2 – Correct:
Initially limited to tropical countries, the 2020 amendment expanded ISA membership to all UN member states, making it a truly global alliance. - Statement 3 – Correct:
A key mission of the ISA is to unlock $1 trillion in solar investments by 2030, alongside lowering solar technology and financing costs.

GS Paper III – Indian Economy and issues relating to growth, development and employment – Fiscal deficit, taxation, investment, macroeconomic stability
Important Keywords
For Prelims:
- Nominal GDP, Real GDP, Fiscal Deficit, Tax Buoyancy, Capital Expenditure, Crowding Out Effect, Private Corporate Investment, PLI Scheme, Government Borrowing, Bond Yields
For Mains:
- Fiscal Space Constraint, Nominal vs Real Growth Dilemma, Revenue–Expenditure Gap, Public Capex Multiplier, Investment-led Growth, Macroeconomic Stability, Policy Transmission Failure
Why in News?
The Union Budget 2026 is in focus as it will be presented amid slowing nominal GDP growth, weak tax buoyancy, and subdued private investment, raising concerns about the government’s fiscal space and its ability to revive economic growth.
When the Finance Minister prepares the Union Budget, it is not a blank-slate exercise. Her choices are tightly constrained by:
- Committed expenditures (salaries, pensions, interest payments)
- Revenue performance of the current year
- Overall macroeconomic conditions
Looking at how the economy performed in 2025–26, three big macroeconomic worries stand out.
Budget 2026: Three Macro Worries for the Finance Minister
1. Weak Nominal GDP Growth (Most critical concern)
Why nominal GDP matters more than real GDP for Budget
- Nominal GDP = value of goods and services at current prices
- Real GDP = growth adjusted for inflation
- Budget calculations (tax revenue, deficit, borrowing) are based on nominal GDP, not real GDP
The problem
- Nominal GDP growth has fallen to ~8%, the lowest in many years
- In February 2025 Budget, the government assumed 10.1% growth
- This gap creates a revenue shortfall
Why it is dangerous
If nominal GDP grows slower than expected:
- Government earns less tax revenue
- It must either:
- Borrow more → higher interest rates, crowding out private investment
- Cut spending → hurts poor, R&D, infrastructure, defence
Thus, weak nominal GDP directly weakens Budget arithmetic
2. Weak Tax Buoyancy (Revenue problem)
What is tax buoyancy?
It shows how much tax revenue grows when GDP grows.
- Buoyancy of 1 → tax grows at same rate as GDP
- Government assumed 1.1
- Actual buoyancy is only 0.6
What this means
Even when GDP grows:
- Tax revenues are growing much slower
- GST, income tax, corporate tax all underperforming
- Tax growth is below even weak GDP growth
Impact
- Bigger fiscal stress
- Less money for welfare and capital expenditure
- More borrowing pressure
This means the government’s revenue engine is misfiring
Weak Private Corporate Investment (Growth problem)
Despite:
- Corporate tax cuts (since 2019)
- Massive government capex (roads, ports, rail)
- PLI subsidies
- Income tax relief
- GST cuts to boost demand
Private investment is still low
- Corporates are not expanding capacity
- Demand is not strong enough
- Sales growth is weak
- Firms prefer sitting on cash rather than investing
New worry: Global investors pulling out
- FPI outflows rising
- Rupee under pressure
- Exchange rate instability
- Political & economic concern for FM
Without private investment, sustainable job creation is impossible
Macro-Political Implications for the FM
- Harder to meet fiscal deficit targets
- Less room for:
- Tax cuts
- New schemes
- Big announcements
- Political pressure due to:
- Rupee weakness
- Investor sentiment
- Employment concerns
What the FM may try in Budget 2026 (Policy Direction)
Boost nominal GDP
- Demand support (targeted, not populist)
- Export incentives
- Services sector push
- Manufacturing competitiveness
2. Improve tax buoyancy
- Widen tax base
- Rationalise GST slabs
- Technology-based compliance
- Avoid aggressive rate cuts
3. Crowd-in private investment
- Policy stability
- Faster clearances
- MSME support
- Long-term credit availability
- Reduce regulatory uncertainty
CARE MCQ
With reference to Union Budget formulation, consider the following statements:
- Nominal GDP is more important than real GDP for budgetary calculations.
- Weak tax buoyancy implies tax revenues grow faster than GDP.
- Weak private investment reduces the effectiveness of public capital expenditure.
Which of the statements given above is/are correct?
A. 1 and 3 only
B. 1 and 2 only
C. 2 and 3 only
D. 1, 2 and 3
Answer: A
Explanation:
- Statement 1 is correct – Budget estimates are based on nominal GDP.
- Statement 2 is incorrect – weak buoyancy means tax grows slower than GDP.
- Statement 3 is correct – private investment is required to crowd in growth.
