Impact of US Fed Interest Rate Decisions on the Indian Stock Market

The Indian stock market is significantly influenced by the decisions of the US Federal Reserve, especially its “interest rate policies”. Whenever the US Fed announces changes, even a slight increase or decrease in interest rates can cause notable fluctuations in Indian stocks. This high sensitivity is because these rate changes affect foreign investments. A rise in US rates can make it more attractive for investors to pull funds out of India, while a decrease may encourage them to invest more.
 

In contrast to the previous year’s strong inflows, FY 2024–25 witnessed a sharp reversal in foreign investment trends. Foreign portfolio investors (FPIs) withdrew around Rs. 1.27 trillion (Rs. 1.27 lakh crore) from Indian equities, marking the second-largest annual outflow on record amid global uncertainties.

This shift highlights cautious foreign sentiment, driven by factors such as global economic volatility, trade tensions, and changing interest rate dynamics, even as domestic investors helped cushion the market impact.

In this article, we will explain in detail why and how the US Fed interest rate changes affect the stock market. We will cover both scenarios of rate hikes and cuts.

Key takeaways

• US Fed interest rate changes affect the stock market by impacting borrowing costs and international investment flows.
• Higher US interest rates make it expensive for foreign investors to borrow, causing them to shift funds from Indian markets to the US.
• Lower US rates reduce borrowing costs. This encourages foreign investors to invest in higher-growth markets like India.

Primarily, US Fed interest rate changes affect the stock market by influencing:

• The cost of borrowing
• Global investment flows

Be aware that foreign investors often borrow money from US markets, where interest rates are low. They then invest in developing countries like India, where returns are higher. When the US Fed raises interest rates, borrowing becomes more expensive for these investors. This leads them to pull funds out of emerging markets like India.

Conversely, when the Fed lowers rates, borrowing costs decrease. This encourages more investments in India, as now investors can earn higher profits.

It is worth mentioning that several foreign investors choose India over the US because it offers higher growth potential. The US is a mature market with fewer growth prospects, whereas India is a developing economy and presents numerous opportunities for capital appreciation.

Additionally, India offers higher interest rates compared to the US. This makes it attractive for foreign investors to earn a greater return on their investments. Let’s understand this situation through an example:

1. Say a foreign investor borrows money in the US at a 3% interest rate.
2. They invest it in Indian markets, where returns can be as high as 12%.
3. If the same investor borrowed funds in India, the interest rate could be 7-8%.
4. This can significantly reduce their profit margin.

Therefore, by borrowing cheaply in the US and investing in India, investors can easily maximise their profits and benefit from the difference in interest rates. For those unaware, this practice is known as the "carry trade". Generally, it drives capital inflows to Indian markets.

US Fed interest rate changes affect the stock market through both a rate hike and a rate cut. Let’s see how a US Fed rate hike works:

• Less attractive Indian markets: When US rates go up, foreign investors pull their money out of Indian markets. This is because the returns from the US (like government bonds) become more appealing than the Indian

  stock market. Hence, foreign investors move their money from India back to the US.

• Weaker Indian rupee: Be aware that the US dollar strengthens due to higher interest rates and the rupee weakens. Now, this causes foreign investors to get less return when they convert their investments from rupees back to dollars. Such a situation discourages them and they often decide to shift investments to better markets.  
• Short-term investors sell their investments: While long-term investors might stay, those who are investing for the short term usually pull out. A weaker rupee and volatile markets make it harder for them to manage their investments. This reduces their returns and most prefer to square off their positions. 

A US Fed rate cut has a direct impact on global liquidity and investor sentiment, influencing Indian stock markets in multiple ways. Typically, lower US interest rates reduce bond yields and weaken the dollar, making emerging markets like India more attractive for investors.

This often leads to increased foreign portfolio investment (FPI) inflows, supporting equity markets and boosting indices like Sensex and Nifty. 

Improved liquidity also enhances risk appetite, resulting in broader market participation.

Rate-sensitive sectors such as banking, NBFCs, real estate, and automobiles tend to benefit the most, as lower global rates improve borrowing conditions and demand outlook.

However, the impact is not always uniformly positive. Markets may remain volatile in the short term, as investors assess global economic signals, inflation trends, and central bank guidance before taking directional bets.

Overall, while a Fed rate cut generally supports Indian equities through liquidity inflows and positive sentiment, its actual impact depends on broader global and domestic economic conditions.
