RBI Alerts Against AI-Driven Rally in Asian Markets

The Reserve Bank of India (RBI), in its latest Financial Stability Report, has confirmed the existence of a potential bubble across the Asian markets, calling for caution by investors. The warning has been made amidst the increasing interest among Indian investors for foreign AI equities, which has shown an alarming rise in the last year. It has been reported that Indian retail participation in global stocks has been rising, and the top destinations for Indian capital were the US, Japan and Taiwan, driven by AI-linked tech stock rallies.

In 2025, Foreign Institutional investors (FiIs) also withdrew ₹1.9 lakh crore from Indian equity markets. A lot of this money probably went to developed markets because of AI euphoria.

Strong Numbers But Concentration Risk

Data in the report shows that Asian markets have delivered impressive year-to-date gains. South Korea's KOSPI has surged by 72.3 per cent, making it the strongest performer among major Asian markets. Hong Kong's Hang Seng has risen by 27.4 per cent. The MSCI Asia-Pacific index, which tracks the region as a whole, is up 23.5 per cent. Taiwan's TAIEX has gained 22.5 per cent, and Japan's TOPIX has advanced 21.7 per cent, while China's CSI 300 has lagged behind with a 14.8 per cent increase.

Although these numbers look strong, the RBI stressed that the growth is uneven. Because so few companies are driving such a large share of the returns, the risk of sudden swings in investor mood is higher. If confidence in AI-linked firms weakens, the overall market could fall sharply.

The sharp rise in share prices across the region is being powered mainly by a handful of large technology companies connected to artificial intelligence (AI). This heavy dependence on a small group of firms, the RBI warned, could make markets unstable and more vulnerable to sudden downturns.

The central bank explained that if American stock markets face a major fall, the impact could spread quickly across the world. Because Asian markets are now closely tied to the same AI-driven optimism seen in the United States, a correction in US equities could drag down Asian indices as well. In simple terms, when only a few companies are responsible for most of the gains, any trouble in those companies can shake the entire market.

AI Optimism Fuels Uneven Growth

The RBI noted that the excitement around artificial intelligence is clearly visible in Asia. Big technology firms are driving most of the rise in share prices, just as they are in the US. The report pointed out that in several Asian countries, only a very small number of stocks are contributing to half of the total returns.

For example, in South Korea's KOSPI index, just two companies are responsible for 50 per cent of this year's gains. In Taiwan, a single company alone accounts for half of the rise in the TAIEX index. Hong Kong's Hang Seng index shows a similar pattern, with six firms making up half of the returns. In the US, seven companies are behind half of the S&P 500's performance. This shows how concentrated the growth has become, meaning the benefits are not spread evenly across the market.

Heavy Spending on AI Raises Debt Concerns

However, the RBI warned that companies are now increasingly turning to borrowing to meet these huge costs. Debt financing has already gone up and is expected to rise further in the coming years. The report added that there are complicated financial arrangements between these firms, where they lend and borrow from each other in circular ways. This kind of structure is helping fuel a credit boom in the AI sector, but it also adds to the risks if the cycle breaks down.

RBI's Message

In clear terms, the RBI's report suggests that while AI is driving excitement and strong gains in stock markets, the reliance on a few companies makes the system weak. If investor sentiment changes or if US markets face a sharp fall, the shock could spread quickly to Asia. At the same time, the massive borrowing needed for AI investments could create financial stress in the future.

The central bank's warning is a reminder that rapid growth based on narrow foundations can be dangerous. Markets may look strong on the surface, but the concentration of gains and rising debt underline the need for caution.

Indian Retail Participation in Global Equities

In 2025, a lot of Indian investors, especially younger ones, kept putting money into huge global tech and AI businesses like Nvidia, Microsoft, and Google. They used apps like Vested, INDmoney, and Groww that let them buy small parts of expensive foreign stocks. While we don't have exact numbers, experts believe a good chunk of the ₹20,000 crore Indians sent abroad for investments went into these kinds of AI-related stocks.

At the same time, the Indian government made it easier and clearer to invest overseas through GIFT City, a special financial zone. This made it easier for more people to invest in global markets in a legal and organised way.

Back home, Indian mutual funds also saw record growth. People kept putting money into SIPs (Systematic Investment Plans), showing that investors are now spreading their money across both Indian and international markets. Some mutual funds that invest in global companies are slowly becoming popular too, but many people still don't know about them or find the options limited.
