The Drain of Wealth Theory: Features & Impact


In the annals of history, few chapters have been as contentious and impactful as the colonization of India by England. This period witnessed the emergence of the “Drain of Wealth theory“, which sheds light on the massive economic exploitation India endured during British colonial rule. As India became a coveted territory for the British Empire, a systematic outflow of wealth and resources from India to England ensued.

In this article, we will explore the historical context, mechanisms, and consequences of the Drain of Wealth, which stands as a stark reminder of India’s economic exploitation at the hands of England during the colonial era.

What is the Drain of Wealth Theory?

The Drain of Wealth Theory was defined and popularized by Dadabhai Naoroji, an Indian scholar, politician, and economist. Naoroji, often referred to as the “Grand Old Man of India,” extensively studied and analyzed the economic impact of British colonial rule on India.

In his seminal work titled “Poverty and Un-British Rule in India,” published in 1901, Naoroji articulated the Drain of Wealth Theory, providing comprehensive insights into the economic exploitation that India endured during British colonial rule. His work played a crucial role in shaping the understanding of India’s economic condition during that period and highlighting the adverse consequences of colonial policies on the Indian economy.

Historical Context: British Colonial Rule in India

The Drain of Wealth Theory relates to economic exploitation during colonial times. According to the mercantilist theory, an economic drain occurs when a country faces an unfavorable trade balance, leading to the outflow of gold and silver.


In India, the drain initially favored the country, with the East India Company importing bullion worth $20 million to balance its exports against Indian imports before the Battle of Plassey in 1757.

However, after the Battle of Plassey, the East India Company gained political power and monopolistic control over the Indian economy. This reversed the situation, and the drain of wealth from India to England began as the British exploited their newfound authority.

The British servants enjoyed a privileged status, amassing wealth through practices like Dastak (free trade passes), Dastur (customary gifts), Nazarana (tributes), and private trade. These practices facilitated the outflow of wealth from India to England.

To consolidate their economic dominance, the British government restricted or prohibited the importation of Indian textiles into England. Penalties were imposed on both weavers and sellers for wearing or using Indian silks and cotton in England.

Thus, the drain of wealth severely impacted India’s economy. Local industries, especially textiles, suffered as they were suppressed to favor British products. This contributed to deindustrialization, exacerbating poverty and unemployment.

Key Features


The Drain of Wealth Theory highlights significant aspects of economic exploitation during the colonial period, particularly under British rule in India.

  • Economic exploitation during the colonial period
  • Indirect Taxes impacted Indian trade
  • British motivation for conquering India: access to cheap raw materials
  • Indian income was spent on costly imports, benefiting Britain
  • Utilization of Indian labor at lower wages for British interests
  • British colonial rule in India was funded by Indian revenue, draining India’s wealth.

Estimated Amount of Drain during Colonial Rule

Indian leaders and economists provided varying estimates of the amount of wealth drained from India during British colonial rule:

  1. R.C. Dutt:
    • Estimated that one-half of India’s net revenue flowed out of the country each year.
    • Approximated the amount to be around £20 million in early 20th-century British currency.
  2. MG Ranade:
    • Declared that more than a third of India’s national income was taken away by the government in different forms.
  3. Dadabhai Naoroji:
    • Claimed that approximately one-fourth of the money raised in India went to England each year.
    • Estimated this to be around $12 million per year.
  4. William Digby:
    • According to his calculations, the annual drainage was estimated at £30 million.

These estimations highlight the significant economic drain that India endured during British colonial rule, emphasizing the scale of exploitation and its adverse impact on India’s economic development.

Impacts of Drainage of Wealth

The Drain of Wealth theory had significant consequences for India:

1. Economic Growth Hindrance: The outflow of wealth impeded India’s economic growth, affecting employment and income prospects for its people.


2. Capital Shortage and Industrial Stagnation: The drain of capital to England resulted in a shortage of productive resources, hindering significant industrial development in India.

3. Impoverishment of Peasantry: Economist R.C. Dutt argued that the drain primarily affected land revenue, leading to the impoverishment of the peasantry.

4. Financing Britain’s Industrial Revolution: India’s wealth served as a substantial source of financing for Britain’s Industrial Revolution, accelerating England’s economic progress.

5. Missed Opportunity for India’s Industrial Revolution: The drain diverted resources and capital away from India, stifling the growth of Indian industries and preventing the nation from experiencing its own industrial revolution.

The Drain of Wealth significantly shaped India’s economic landscape during colonial rule, perpetuating poverty and hindering its path to industrialization.

The drain of resources to Britain financed England’s Industrial Revolution while hindering India’s progress. This historical context emphasizes the impact of colonial rule and its lasting legacy on India’s economic journey toward independence and prosperity.
