Critics and cautious observers warn that chasing a $25 billion foreign investment boost carries significant hidden risks that could undermine domestic economic sovereignty. The primary concern is that increased reliance on foreign portfolio flows makes the Indian economy highly susceptible to the 'taper tantrum' effect. If global interest rates rise or if there is a sudden shift in risk appetite in the United States or Europe, these massive funds could exit the Indian market just as quickly as they entered, causing sharp currency depreciation and market crashes.
There is also the issue of market distortion. When large passive funds enter a market based on index weightings rather than the underlying performance of individual companies, it can lead to asset bubbles. Stocks that are included in the indices may see their prices artificially inflated, while smaller, potentially more innovative domestic firms are starved of capital because they do not meet the criteria for index inclusion. This creates a two-tier market that does not necessarily reflect the true health of the broader Indian economy.
Furthermore, the regulatory pressure to cater to global index providers may force the government to prioritize the needs of foreign investors over domestic policy goals. For instance, if index providers demand specific tax exemptions or changes to capital controls, the government might feel compelled to comply to maintain its index status, even if those changes are not in the best interest of the local population or domestic industry.
Finally, the volatility associated with large-scale foreign inflows can complicate the work of the Reserve Bank of India. Managing the exchange rate becomes significantly more difficult when billions of dollars move in and out of the country in a short period. This forces the central bank to intervene more frequently, which can lead to unintended consequences for domestic inflation and interest rate management, ultimately creating a more unstable environment for local businesses and consumers.
