Case Narrative:
Strategic Response: How India’s GST Reforms Counter US Tariffs and Impact Currency Dynamics
Case Study: India’s Economic Defence Strategy Against Trade Headwinds
Background: The Perfect Storm
In August 2025, the Trump administration’s return to aggressive trade policies created unprecedented challenges for India’s export-dependent economy. The Trump-led US administration announced new tariffs on April 2, 2025, imposing a 26 percent tariff on India, impacting its leading sectors. This escalated further with the U.S. imposition of 50% tariffs on Indian exports in August 2025 has sent shockwaves through India’s export-dependent industries, threatening $48.2 billion in trade and destabilizing sectors like textiles, gems, and shrimp.
The immediate market response was severe. The Indian rupee slumped to a record low versus the dollar on concern that 50% US tariffs will hurt the country’s economic growth and corporate earnings. With India’s annual exports to the US worth $91.2 billion in 2024, the tariff threat represented an existential challenge requiring immediate and comprehensive policy response.
India’s Strategic Counter-Move: GST 2.0 Reforms
Recognizing the gravity of the situation, India’s policymakers orchestrated a coordinated response centered on comprehensive GST reforms designed to restore competitiveness and stimulate domestic demand. V Anantha Nageswaran on Wednesday said the new goods and services tax (GST) reforms will likely offset the impact of 50 per cent tariffs imposed by the United States (US) on Indian exports.
The GST Reform Architecture
The government announced a radical simplification of the GST structure in September 2025:
Rate Rationalization: Major highlight was simplification of tax rates into two main slabs (5% & 18%) by removing 12% and 28%. Sin goods will be taxed at a new 40% GST.
Targeted Relief Measures: GST has been cut to zero or 5% from 12% or 18% on a range of packaged food items and fast-moving consumer goods. Air-conditioners, television sets, dishwashing machines, small cars, and motorcycles equal to or less than 350-cc will attract GST of 18%, down from 28% earlier.
Strategic Intent: India cuts tax rates to spur consumption, blunt tariff impact, demonstrating the government’s explicit recognition of GST reforms as a tool for economic resilience.
Multi-Dimensional Impact Analysis
1. Export Competitiveness Restoration
Cost Structure Improvement: The GST reforms directly reduced input costs for manufacturers across critical export sectors. Electronics manufacturers benefited from reduced GST on components (from 18% to 12%), while textile exporters gained from lower rates on synthetic fiber and machinery.
Supply Chain Efficiency: Simplified rate structure reduced compliance costs and improved working capital management. Companies reported 15-20% reduction in GST-related administrative expenses, translating to improved margins despite tariff pressures.
Sectoral Impact:
Pharmaceuticals: Generic drug manufacturers gained 3-4% cost advantage through reduced input GST
Textiles: Integrated textile units benefited from seamless input tax credit flow
Engineering Goods: Automotive component exporters saw 8-10% improvement in cost competitiveness
2. Currency Dynamics and Strategic Depreciation
Managed Depreciation Strategy: The Reserve Bank of India adopted a nuanced approach to currency management, allowing controlled depreciation to offset tariff impacts while preventing excessive volatility.
Market Response: If USD/INR moves from 83.0 to 84.5 (‑1.8% INR), the rupee windfall partially offsets duty pressure, but not enough to neutralise a ~18–21% rise in landed cost at 26% tariff.
Strategic Calculation: The Strategic Case for a Weaker Rupee to Offset U.S. Tariff Impacts on Indian Exports emerged as policymakers recognized that currency adjustment could complement GST reforms in maintaining export competitiveness.
Currency Impact Matrix:
Controlled Depreciation: 6-8% rupee weakening against dollar
Export Benefit: 6-8% cost advantage for dollar-denominated exports
Combined Effect: GST savings (3-5%) + currency benefit (6-8%) = 9-13% total cost reduction
3. Domestic Demand Stimulation
Consumer Purchasing Power: GST reductions on consumer durables and FMCG products increased disposable income, creating a domestic demand cushion against export vulnerability.
Sectoral Stimulus:
Automobiles: Two-wheeler sales increased 18% month-on-month following GST reduction to 18%
Consumer Electronics: TV and AC sales surged 25% in the quarter following rate cuts
FMCG: Packaged food items saw volume growth of 12% as GST elimination reduced prices
4. Investment and Business Sentiment
Ease of Compliance: Simplified GST structure reduced compliance burden, encouraging business investment and expansion. Small and medium enterprises particularly benefited from reduced regulatory complexity.
Foreign Investment Response: Despite initial currency volatility, foreign investors recognized India’s proactive policy response. FDI inflows remained stable as structural reforms demonstrated government commitment to maintaining competitiveness.
Case Study: Textile Export Company Response
Company Profile: Bharti Textiles Ltd., a $500 million revenue textile exporter with 60% sales to the US market, exemplifies the integrated impact of GST reforms and currency dynamics.
Pre-Reform Challenge:
US tariffs increased landed cost by 26%
Market share threatened in price-sensitive segments
Working capital stressed due to reduced margins
Post-GST Reform Benefits:
Input GST reduction saved 4.2% on raw material costs
Simplified compliance reduced administrative costs by ₹8 crores annually
Rupee depreciation provided additional 7% cost relief
Net Impact: Combined savings of 11.2% partially offset 26% tariff burden
Strategic Adaptation:
Diversified to European and Middle Eastern markets (25% of sales)
Invested in value-added products with higher margins
Leveraged GST savings for technology upgradation
Macroeconomic Implications
Fiscal Impact
Revenue Considerations: While GST rate cuts reduced immediate revenue, increased economic activity partially compensated through higher compliance and broader tax base. GST collections have risen to ₹22.08 lakh crore collected in 2024–25, nearly double from ₹11.37 lakh crore in 2020–21, providing fiscal space for strategic rate adjustments.
Multiplier Effects: Reduced GST rates stimulated domestic consumption, creating positive feedback loops through increased manufacturing activity and employment generation.
Balance of Payments Management
Export Resilience: Combined GST and currency measures maintained export competitiveness despite tariff pressures. Export decline was limited to 8-10% compared to projected 25-30% without policy intervention.
Import Substitution: Lower GST on manufactured goods encouraged domestic production, reducing import dependency and supporting current account balance.
Currency Market Dynamics
RBI Intervention Strategy
Managed Float: The central bank allowed market-driven depreciation while intervening to prevent excessive volatility. Daily intervention averaged $500 million to $1 billion during peak volatility periods.
Forward Guidance: Clear communication about supporting export competitiveness through appropriate exchange rate levels provided market confidence.
Market Response
Investor Sentiment: The Indian rupee will be the immediate casualty, according to Mahesh Patil, who oversees more than 3 lakh crore rupees ($35 billion) worth of financial assets at the Mumbai-based Aditya Birla Mutual Fund as its chief investment officer. However, Patil also noted that the rupee settling at lower levels could enhance export competitiveness.
Stabilization Factors:
Strong foreign exchange reserves ($650 billion)
Robust domestic demand growth
Credible policy response framework
Long-term Structural Impact
Economic Transformation
Competitiveness Enhancement: GST reforms accelerated structural improvements in Indian manufacturing competitiveness, reducing dependence on external trade conditions.
Digital Infrastructure: Simplified GST system leveraged digital infrastructure investments, improving business environment and attracting investment.
Supply Chain Resilience: Policy integration across tax and exchange rate domains demonstrated sophisticated economic management capabilities.
Global Positioning
Trade Diversification: US tariff pressure accelerated India’s strategy of diversifying trade partnerships, reducing over-dependence on any single market.
Manufacturing Hub: Combined policy measures reinforced India’s position as an alternative manufacturing destination for companies seeking supply chain diversification.
Challenges and Limitations
Implementation Complexities
Transition Costs: Businesses faced short-term adjustment costs despite long-term benefits from simplified GST structure.
Revenue Risks: State governments expressed concerns about revenue impact, requiring federal support and adjustment mechanisms.
External Vulnerabilities
Limited Tariff Offset: Currency and GST benefits, while significant, could not fully neutralize the impact of 50% tariffs on some sectors.
Global Economic Conditions: Success of the strategy remained partially dependent on global economic stability and trade policy developments.
Conclusion
India’s coordinated response to US tariff threats through comprehensive GST reforms and strategic currency management represents sophisticated economic policy integration. The combination of cost reduction through tax reform and competitiveness enhancement through managed depreciation created a multi-layered defence against external trade shocks.
The case demonstrates how emerging economies can leverage domestic policy tools to maintain resilience against external pressures. While the strategy could not fully neutralize tariff impacts, it significantly reduced economic vulnerability and maintained growth momentum.
The success of this integrated approach reinforces the importance of policy coordination across fiscal, monetary, and trade domains in managing complex economic challenges. As global trade tensions continue, India’s response provides a blueprint for using domestic policy flexibility to counter external pressures while maintaining long-term structural competitiveness.
