Explanations:The concept of an intervention currency is crucial in understanding the monetary policy of a country. An intervention currency is a foreign currency that a country's central bank uses to stabilize its own currency's value. In the case of India, the rupee was historically linked to the pound sterling as the intervention currency. This linkage was a remnant of India's colonial past and the influence of the British Empire on its economic policies.
The break in this association occurred in 1992, which is the correct answer. This change was part of a broader set of economic reforms that India undertook in the early 1990s. These reforms were initiated in response to a severe balance of payments crisis in 1991, which necessitated significant changes in India's economic policy.
The reforms included liberalizing the economy, reducing the role of the state in economic activities, and opening up the country to foreign investment. The decision to break the rupee's association with the pound sterling was a key component of these reforms, as it allowed India to have more control over its monetary policy and to align its currency more closely with the global economic environment.
Understanding the historical context of this change is important for comprehending the evolution of India's economic policy. The early 1990s marked a significant turning point in India's economic history, with the rupee's disassociation from the pound sterling being a pivotal moment in this transformation.
