Indian benchmark indices began the December 15 session on a weak footing, snapping a two-session gaining streak that had briefly restored investor confidence. The opening decline reflected a confluence of pressures - a sharply weaker rupee, continued foreign capital outflows, and a negative lead from global equity markets. Together, these factors have reinforced near-term uncertainty even as broader domestic economic indicators remain relatively stable.

At around 9:50 am, the Sensex was down over 320 points, or about 0.4 percent, at 84,944, while the Nifty 50 declined 112 points to trade near 25,935. The selling was broad-based rather than sector-specific, suggesting a risk-off bias rather than stock-level profit-taking.

The most immediate trigger unsettling markets has been the sharp depreciation in the Indian rupee. On Monday, the currency slipped to a fresh record low of 90.6 against the US dollar, marking the third consecutive session of new lows. Currency weakness has emerged as a growing concern for equity investors, particularly foreign institutions, as it erodes dollar returns and raises questions around external balance stability.

The rupee’s slide has been attributed to a mix of factors, including the absence of progress on a potential India–US trade agreement, weak capital inflows, and sustained demand for dollars. This currency pressure has coincided with persistent selling by foreign institutional investors. According to data from the National Stock Exchange, FIIs were net sellers of Indian equities worth ₹10,719.95 crore in the previous session, marginally offset by purchases of ₹10,323.69 crore. The net selling trend has now become a defining feature of recent market action.

In contrast, domestic institutional investors have continued to provide some counterbalance, remaining net buyers. However, their participation has so far been insufficient to decisively offset the scale and consistency of foreign outflows.
