India is confronting a complex economic challenge as it experiences significant foreign capital outflows despite maintaining stable macroeconomic fundamentals and a rapidly growing economy. Chief Economic Advisor V. Anantha Nageswaran recently highlighted sluggish private capital expenditure as a major concern, compounded by increased capital gains taxes that have reduced the country’s attractiveness to foreign investors at the margin.

Data-driven reassessments suggest that India may need to reconsider its tax policies to better stimulate investment. Although corporate tax rates were lowered in 2019 to encourage private sector spending, capital gains taxes on investors were simultaneously raised to offset revenue losses from the corporate rate cuts. This combination has led to only modest increases in private investment, with public sector spending accounting for much of the growth. Additionally, corporate investment in research and development has lagged, raising concerns about India’s competitiveness in emerging fields such as artificial intelligence.

Authoritative voices argue that easing capital gains taxes while adjusting corporate tax rates upward could make Indian assets more competitive relative to other emerging markets, thereby attracting foreign portfolio investors (FPIs) and freeing more domestic capital for sectors like the deep technology ecosystem, which require risk capital. This approach contrasts with reliance on fiscal austerity, which past experiences in developing economies advise should be approached cautiously.

The capital outflow dilemma is also tied to a narrowing yield spread between Indian rupee assets and U.S. dollar-denominated assets. Over the past five years, the yield differential has shrunk from an average of 350–400 basis points to around 250 basis points. This reduction partly reflects a diminished inflation gap; India’s inflation has converged with, and at times fallen below, U.S. inflation levels. While the Reserve Bank of India’s comparatively less aggressive monetary tightening in response to the U.S. Federal Reserve’s hikes can be theoretically justified, it has meant that local interest rates have remained relatively low, making rupee-denominated assets less attractive to foreign investors.

Another factor complicating the situation involves distortions between the currency and equity markets. The Indian rupee has depreciated more than 10% over the past year—a move consistent with textbook economic theory—in response to high oil prices and foreign portfolio investor sell-offs. Measured by the Real Effective Exchange Rate, the rupee now appears undervalued. However, India’s equities have not experienced a corresponding market correction. This divergence is attributed to consistent inflows from domestic mutual funds, which maintain investments in Indian equities through systematic investment plans, thus creating a “liquidity put.” As FPIs perceive Indian equities to be relatively overvalued, they continue to sell, but domestic mutual funds absorb much of the selling pressure without triggering broad market declines. This dynamic reinforces foreign investor caution, further pressuring capital accounts and the currency.

The resulting disconnect means that the self-correcting price mechanisms in currency markets do not effectively transmit to equity markets, complicating efforts to restore equilibrium. Addressing these intertwined factors will require policy responses that go beyond conventional textbook economics and consider evolving data and market signals in real time.
