Deutsche Bank survey of institutional clients: "Biggest risk in 2026" — more than half chose "technology bubble burst," with "new Fed chair slashing interest rates" coming second.

In the eyes of institutional investors on Wall Street, the biggest market threat in 2026 has already been clearly identified: the bursting of the AI-driven tech stock bubble.

Deutsche Bank’s latest client survey shows that 57% of respondents list the bursting of the tech bubble as the top of the three major risks, marking a historic high for the proportion choosing any single risk.

The second-ranked risk is also noteworthy—the prospect of a new Federal Reserve Chair pushing an aggressive rate-cut policy, triggering market volatility. This concern reflects deep anxiety among investors over monetary policy uncertainty. The private capital crisis ranks as the third major risk.

Deutsche Bank analyst Jim Reid noted in the report that he has never seen a single risk so far ahead of other options, making it the “overwhelmingly dominant concern” for 2026. Such a highly unified level of alertness is itself noteworthy.

By contrast, only 9% of respondents selected a hard landing for the U.S. economy, indicating that the market sees a U.S. recession as a "major surprise."

Tech Bubble Concerns at a Historic Peak

57% of respondents listed the bursting of the tech bubble as one of the three major risks for 2026, far exceeding any previous single risk option. Reid noted that such overwhelming consensus is “unprecedented,” highlighting institutional investors’ profound concerns over current AI-related stock valuations.

Compared to the internet bubble in the late 1990s, today’s potential bubble shows different characteristics.

Reid analyzed that although the 1990s bubble was global, today’s potential over-concentration is in U.S. AI-related stocks. However, today’s leading AI enterprises are larger and more systemically important—“arguably even more systemically important than banks in 2008.”

Reid posed a contrarian thought: with so many investors worried about a bubble, it may suggest that the market hasn’t yet reached the extreme frenzy often necessary for a bubble to burst.

Fed Independence Risk Ranks Second

The prospect of a new Federal Reserve Chair pushing for aggressive rate cuts and triggering market turmoil ranks as the second biggest risk, a ranking that is “surprising.”

Reid said that considering the difficulty in persuading the entire Federal Open Market Committee to support aggressive rate cuts, the high level of concern over Fed independence is “shocking.”

This concern reflects the market’s attention to monetary policy continuity and central bank independence, especially given the political environment’s potential influence on central bank decision-making. According to a previous article in Wallstreetcn, Trump stated explicitly on Wednesday that the next Fed chair must be someone who believes in “big rate cuts,” and “mortgage rates will drop further.” He believes the next Fed chair should consult him on rate settings.

Private Capital Crisis Draws Attention

The private capital crisis completes the top three risks, an option that has frequently appeared in recent client conversations.

Reid pointed out that earlier bankruptcies such as First Brands and Tricolor have heightened market concerns.

The core issue facing the industry is a lack of transparency, making it hard to assess risk exposure and contagion risk. Such information asymmetry increases the unpredictability of systemic risk.

Other Risks: Yield Surges, Rate Hikes...

Rising bond yields and unexpected central bank rate hikes also made it into the top five risks. Notably, only 9% of respondents listed a U.S. hard landing among the top three risks, indicating a widespread belief that the probability of a U.S. recession is low.

For comparison, in the survey in early 2025, 39% of respondents chose global trade war as the biggest risk, while 36% chose tech bubble. After the DeepSeek incident and Trump’s announcement of reciprocal tariffs in April, those consensus risks appeared to be becoming reality, but then reversed sharply.
