The federal funds rate is the rate at which American banks borrow money from one another overnight, and it is determined by the Federal Reserve (Fed), the US central bank. On 29th October 2025, the Fed reduced the rate by 25 basis points to a range of 3.75 - 4.0 %. This is the second Fed rate cut this year after the first one in September 2025.This rate is the keystone of global liquidity. By lowering its rate, the Fed makes borrowing cheaper, which impacts global financial markets, including India. When the Fed reduces rates, the resulting inflow of foreign funds tends to flow into equities in rapidly expanding economies, such as India.Here is an in-depth review of the effect of this monetary decision on Indian equities, sectoral indices, and investor sentiment.Why does the Fed cut its rate, and why does it impact Indian markets?The US Federal Reserve decides to cut its interest rate to support a slowing economy and tame inflation expectations. Mounting unemployment, combined with declining business activity, set against a backdrop of strong global uncertainty, pushes the Fed toward accommodation.A rate cut by the Fed boosts lending, consumption, and prevents further economic deceleration. The recent rate cut is driven by the ongoing US inflation and political gridlock due to a prolonged government shutdown.This rate cut has a ripple effect on India, influencing currency movement, interest rates, and capital flows. A rate cut reduces the overall borrowing cost. This means even the RBI may cut the Repo rate, which translates to higher liquidity in the system, businesses, and an overall positive sentiment for the stock market.When the Fed rate goes lower, this means the dollar weakens. As a result, foreign investors have funds available to invest in emerging markets like India. Also, the Rupee gains strength against the dollar. This means imports become cheaper and that benefits import-heavy sectors like Oil and Gas and commodities.Following the announcement of the rate cut, Nifty and Sensex were down 0.31% and 0.27% respectively, at the start of the market, indicating caution despite increased liquidity.Nifty Pharma fell 0.76%, FMCG and Metal each by 0.4%. Realty, however, showed a gain of 0.5%, and the private banking sector witnessed a minor decline of 0.2%. However, these changes are often short-lived, and the markets recover as this information is discounted. The market impact of Fed rate cutsConsidering the earlier rate reductions (2024–2025), Indian markets have been following a pattern of volatility bursts, rallying at times, and partially recovering the next day. The impact is typically short-term and is soon replaced by the domestic macro-environment, RBI policy, and sectoral events.

These outside events, however, are rapidly digested in the Indian market.Caution is key with uncertainty over further rate cut The recent US Fed rate cut brings short-term volatility to the Indian financial market. However, its broader impact depends more on domestic fundamentals, corporate earnings, and the RBI’s policy stance.There is no certainty about the future rate cut in December, as Fed Chair Jerome Powell stated, “further reduction in the policy rate at the December meeting is not a foregone conclusion, far from it.” This would also impact Indian and its financial markets. To survive and sustain, the key is to be cautious.
