TLDR: Singapore’s financial regulator, the Monetary Authority of Singapore (MAS), has issued a stern warning regarding the elevated valuations in the technology and artificial intelligence equity segments. In its annual Financial Stability Review released on November 5, 2025, MAS cautioned that a decline in optimism about AI’s future profitability could trigger significant market corrections and increased defaults in private credit markets. This assessment follows a recent $500 billion selloff in the semiconductor sector.
The Monetary Authority of Singapore (MAS) has sounded an alarm over what it describes as ‘relatively stretched valuations’ within the technology and artificial intelligence sectors. In its annual Financial Stability Review, published on November 5, 2025, the central bank highlighted growing concerns that the current market optimism surrounding AI’s potential to generate substantial future returns might be overblown, posing a significant risk to financial stability.
The report explicitly warned that a ‘retrenchment of optimism in AI’s ability to generate sufficient future returns may lead to sharp corrections in the broader equity market and further defaults in the private credit market.’ This cautionary statement comes on the heels of a turbulent week for the semiconductor industry, which saw an estimated $500 billion in market value wiped out globally. This selloff was largely attributed to weaker-than-expected earnings guidance from key players such as Palantir Technologies and Advanced Micro Devices.
MAS data revealed a stark divergence between valuation expansion and actual earnings growth in these sectors. A Bloomberg index tracking 45 prominent cloud, semiconductor, and hardware companies is currently trading at approximately 23 times forward earnings, a notable increase from 14 times in April 2025. In contrast, actual earnings estimates for these companies rose by only 13% during the same period, indicating that much of the market’s recent gains have been driven by speculative valuation rather than fundamental profit growth.
Beyond market valuations, the MAS also raised concerns about the operational models of some large technology firms. The report pointed out the use of ‘novel and potentially circular private financing arrangements’ to fund expansion, which places ‘increasing revenue generation pressure’ on these companies. Should revenue growth fail to meet these heightened expectations, their financial positions could face severe tests.

Singapore’s central bank is not alone in its apprehension, joining a ‘global chorus’ of financial authorities, including the Korea Exchange, that have recently warned about the high valuations in tech and AI stocks. The MAS further noted that the broader equity market rebound this year, coupled with rising gold prices and unusual movements in the dollar, collectively reflect an underlying nervousness within the market. The continued divergence between optimistic equity market valuations and rising downside risks to economic growth, according to MAS, heightens the prospect of ‘disorderly corrections’ in the event of unforeseen shocks.
