Sensex hits record 85,000 as rupee nears 95 per dollar

KUALA LUMPUR, 23 JULY 2026 —

India's financial markets have undergone a dramatic transformation over the past quarter century. A new study by Bank of Baroda Research has traced the evolution of the Sensex, the rupee and foreign institutional investor (FII) flows over a 26-year period, revealing how increasingly interconnected these variables have become in shaping India's financial landscape. The report analysed monthly data between FY2000 and FY2026 to understand the relationship between the BSE Sensex, the rupee-dollar exchange rate and FII equity flows. According to the study, India opened itself to global capital following the economic reforms of the 1990s, creating opportunities for foreign portfolio investors to play a major role in the country's capital markets. Sensex's performance Over this period, the benchmark Sensex delivered strong long-term growth. From around 4,749 in March 2000, the index scaled record highs above the 85,000 mark before witnessing some moderation. India's market capitalisation has expanded to nearly $4.5 trillion, equivalent to around 120% of GDP, underscoring the growing importance of equities in the country's economic development.

The currency moved from 43.7 against the US dollar in March 2000 to about 94.8 by March 2026, reflecting a long-term depreciation trend. Despite this decline, the report notes that currency movements and stock market performance have remained closely linked, with several studies globally highlighting the interaction between exchange rates and equity markets.

Here's why One of the most significant findings of the study is that the correlation between these variables has strengthened after the pandemic. During the period between April 2022 and March 2026, the correlation between the Sensex and FII flows rose to 0.7, while the correlation between the Sensex and the rupee increased to 0.6. In addition, the rupee and FII flows also showed a positive relationship. The study also examined whether one variable could help predict another. Through Granger causality analysis, Bank of Baroda found evidence of causality between the Sensex and the exchange rate, as well as between the Sensex and FII flows. This suggests that stock market movements can influence future capital flows and currency trends.

The report also highlighted the presence of volatility clustering in financial markets. In simple terms, periods of sharp movements tend to be followed by further bouts of volatility. Using GARCH models, researchers found that shocks to the Sensex and FII flows have persistent effects, with changes in one variable spilling over into the other. Interestingly, the study found that post-pandemic data exhibited fewer signs of volatility clustering, suggesting that market behaviour may have changed in recent years. The findings underline how deeply integrated India's stock market, foreign capital flows and currency have become. As the country attracts greater global capital and its markets continue to expand, understanding these relationships could become increasingly important for investors, policymakers and businesses navigating a rapidly evolving financial environment.
