The British economic policies in India from mid-18th century to 1947 fundamentally transformed the subcontinent's economy, creating a colonial framework designed primarily to serve British imperial interests.

Trade and Commercial Policies

• Monopolistic trade practices established after Battle of Plassey (1757), eliminating Indian merchants from lucrative sectors
• Free trade for Britain while imposing heavy tariffs on Indian goods in British markets (70-80% duties on textiles)
• Export of raw materials (cotton, jute, indigo) and import of finished goods created unfavorable balance of trade
• Drain of Wealth theory by Dadabhai Naoroji quantified annual economic drain of ₹200-300 million
• Home charges for British administrative costs, military expenses, and guaranteed returns to British investors

Land Revenue Systems and Agricultural Impact

• Commercialization of agriculture forced shift from food to cash crops
• Revenue demand in cash led to peasant indebtedness and land alienation
• Frequent famines (1876-78, 1896-97) due to neglect of food security

Industrial Deindustrialization

• Textile industry destruction: Indian share of world manufacturing fell from 25% (1750) to 2% (1900)
• Discriminatory tariffs: British goods entered India at 2-4% duty while Indian textiles faced prohibitive duties abroad
• Traditional crafts decline: Dhaka muslin, Kashmir shawls, metalwork industries collapsed
• Capital flight: Profits from Indian industries invested in Britain rather than local reinvestment
• Limited modern industry: Only railways, jute mills, and cotton mills serving British export needs

Infrastructure Development for Colonial Exploitation

• Railway construction (1853-1947): 65,000 km network primarily connecting ports to raw material sources
• Guaranteed returns of 5% to British railway investors from Indian revenues
• Port development: Bombay, Calcutta, Madras designed for British trade facilitation
• Telegraph system: Administrative control rather than commercial development
• Irrigation projects: Focused on cash crop regions, neglecting food-producing areas

Financial and Monetary Policies

• Currency manipulation: Closure of Indian mints (1893) benefited British silver interests
• Banking system: Imperial Bank of India and Presidency banks served British commercial interests
• Public debt burden: Indian taxpayers financing British wars and administrative costs
• Budgetary exploitation: Military expenditure consuming 25-30% of Indian revenues

The British economic policies created what R.C. Dutt called "economic colonialism" - systematic underdevelopment through wealth extraction. While infrastructure was developed, it served imperial rather than national interests. Post-independence India inherited this distorted economic structure, requiring decades of planned development to rebuild industrial capacity and achieve economic sovereignty under Constitutional directive principles.
