The Bank for International Settlements warns that the AI investment boom may sow the seeds of long-term financial risks

The Bank for International Settlements (BIS) issued a stern warning in its latest report regarding the current "artificial intelligence (AI) boom" in global financial markets. The report argues that if this trend continues at its current pace, it could evolve into a prolonged investment slump and even trigger broader financial risks and economic shocks.

The report's core concern is that while large technology companies are making unprecedentedly large investments in AI, the commercial returns remain highly uncertain. Currently, companies represented by the five largest "mega-tech companies" are projected to invest over $1 trillion in AI-related fields between the end of 2025 and 2026. This scale of investment is historically rare and has led to a high concentration of global capital markets in the AI ​​sector.

The BIS points out that if the profitability of AI falls short of market expectations, investor sentiment could quickly reverse, leading to a significant contraction in funding. Once funds withdraw from the high-risk, high-investment AI sector, it could not only cause a sharp decline in capital expenditures in the technology industry but also potentially trigger a sustained investment recession. This chain reaction could extend beyond technology companies and spread to the broader economic system through financial markets.

Currently, technology companies are actively leveraging global credit markets to raise funds through large-scale bond and stock issuances to support AI infrastructure development. The historically low corporate credit spreads in recent years, resulting in relatively cheap financing costs, have further fueled the influx of capital into the technology sector. Simultaneously, strong demand for technology stocks in the capital markets has driven up share prices, making it easier for related companies to access funding. For example, some large-scale technology-related financing events have attracted significant market attention, leading some investors to worry whether the market is showing signs of overheating.

Some investment executives at financial institutions have also pointed out that the frequent bond issuances by technology companies may indicate that the market has entered a "bubble zone." If market expectations change, such as continued interest rate increases or AI profitability falling short of expectations, this model of heavily reliant on financing expansion could be quickly impacted.

However, the report also points out that artificial intelligence itself is not entirely negative. In the long term, AI technology has the potential to significantly improve productivity, enhance corporate efficiency, and provide new impetus for global economic growth. Therefore, the current boom contains both potential risks and a genuine foundation for technological progress.

The Bank for International Settlements (BIS) also conducted a historical comparative analysis, arguing that the current wave of AI investment shares similarities with previous technology investment booms, such as the canal construction and railway expansion of the 19th century, and the dot-com bubble of the 1990s. A common characteristic of these periods was that while new technologies were undeniably groundbreaking, capital investment often exceeded the level that could be supported by the eventual commercial returns, ultimately leading to investment corrections or even economic recessions.

The report emphasizes that compared to the past, the impact of financial markets today is broader, and stocks constitute a larger proportion of household assets. Therefore, a significant correction in AI-related assets could have a more pronounced impact on the wealth and spending power of ordinary households. Furthermore, the current heavy reliance on debt financing for AI investments increases the vulnerability of the financial system; a decline in market confidence could trigger a broader credit contraction.

Besides the risks associated with artificial intelligence, the report also mentions other pressures facing the global economy. For example, the impact of geopolitical conflicts on energy markets continues to unfold. Even if some conflicts have eased, their impact on the global energy supply chain has not completely dissipated, particularly the long-term effects of restricted shipping lanes on oil and gas transportation, which could still push up inflation.

Overall, the Bank for International Settlements (BIS) believes that the global economy is currently in a phase characterized by multiple intertwined risks: on the one hand, there is the potential bubble risk brought about by the artificial intelligence investment boom; on the other hand, there is the combined effect of persistent inflation, fiscal pressure, and geopolitical uncertainty. These factors work together to pose greater challenges to the stability of global financial markets in the future.
