European Central Bank Warns AI Market Correction Is Likely Despite Tech Rally

'Worrisome': AI is driving a looming market correction, central bank economists warn

* Economists at the European Central Bank warn heady stock market valuations are likely to suffer a correction, even if they fairly reflect the ways in which AI will transform society. * History suggests investors will demand higher and higher risk premia as the success or failure of key companies becomes pivotal to the global economy, they said in an analysis published this week. * European investors are highly exposed to such a downturn through the dominance of Mag 7 stocks in index funds, they also note.

"Economic research on past technological revolutions points to a worrisome conclusion: a correction of current stock market valuations is likely," the economists wrote in a Monday blog, citing two potential scenarios. A correction could occur because "overconfident, overoptimistic investors" push prices up beyond their fundamental worth, leading to a crash when that exuberance fades, they said. But a fall in prices should be expected, even if current valuations are an accurate reflection of AI's capacity to reshape the global economy and boost corporate profits, they add. watch now VIDEO4:0804:08 Hyperscalers, AI buildout and Treasury yields 'all connected', says Sycamore Tree's Mark Okada Closing Bell The economists cite parallels with the 19th century railway boom, the expansion of electricity and radio in the 1920s, and the rise of the internet in the 1990s -- not the first time the current AI wave has been compared to the dotcom bubble of the early 2000s. In each case, investor nerves about the success of a technology-linked transition spilled over into the wider economy. "As adoption spreads...uncertainty becomes economy-wide. If something then goes wrong with that technology, the whole economy suffers," the economists wrote. This drives investors to demand a higher risk premium, which their analysis found is likely to eventually drive stock prices down, even if profit growth remains robust. "Both views imply a boom followed by a correction, or a pullback from wherever valuations have risen, at some point in the future," they said, noting that this could in turn be followed by a recovery and further climb in stocks. "The exact timing is unknowable in advance. These boom-bust patterns are only identifiable with hindsight." watch now VIDEO7:2007:20 We're 'absolutely' in an AI bubble right now, says Lead Edge Capital's Mitchell Green Squawk Box The blog goes on to warn of the fallout of such a pullback and urged investors to prepare for it. European retail investors are highly exposed, potentially without knowing it, because of the prevalence of "Magnificent 7" stocks in global index funds and pension funds, the economists said. There is a further risk that a sharp correction triggers knock-on effects through fund-based structures that eventually threatens euro area stability, they continued. "Unlike in the dot-com episode, today's starting point leaves markedly less room to cut interest rates or use fiscal policy to cushion the fallout."

European Central Bank Warns That AI Crash Is Looming

Can't-miss innovations from the bleeding edge of science and tech While talk of an AI investment bubble usually centers around the designs of Silicon Valley and Wall Street, the implications reach far beyond the borders of the United States. On Monday, an analysis published by the European Central Bank, first reported by Reuters, made the case that a "market correction" to AI investment euphoria is not only highly probable, but carries the potential for far-reaching consequences in Europe and beyond. The analysis, authored by ECB economists and financial researchers, looked at two explanations for the AI financial bubble. Their first, dubbed the "rational view," is that unprecedented tech investments are justified by "extreme uncertainty" about a developing technology's effects on productivity. For example, in October of last year, the chip giant Nvidia swelled to become the first $5 trillion company on the mere possibility that some quantitative leap in AI's abilities could emerge. If that happens, Nvidia would be the "pick and shovel" salesman to the AI industry's gold rush (of course, that kind of AI motherlode has yet to emerge from the river muck.) "In the worst case in such a scenario, investors lose their investment," the authors write. "But in the best case, the gains are large and genuinely hard to bound. This 'option value' increases the stock valuations of early adopters, causing their price-to-earnings ratios to rise sharply." The second explanation is the "behavioral view." This interpretation holds that "overconfident" and "overoptimistic" investors are essentially losing themselves to the AI hype train, ignoring the rational possibility of either devastating financial losses or unprecedented gains in favor of a live-for-the-moment attitude. When this kind of overconfidence around new tech fades, the authors posit, losses from a market correction can be swift and severe, more so than in the rational scenario. Which of the two scenarios is playing out right now is difficult to say -- and it's likely an unholy blend of both. In any case, the authors write that both views "imply a boom followed by a correction, or a pullback from wherever valuations have risen, at some point in the future." What such a crash could mean for Europe is likewise hard to say without knowing more. The analysis asserts that spark that lights the fire sale probably won't emerge from European markets, but that's not saying much. As the authors conclude, European "households, insurers and pension funds have significant exposures through global index trackers." "The effects of a US correction could extend beyond financial markets to euro area sentiment, financing conditions and hiring," the experts write. "A US AI fallout would not remain a US problem."

Is market heading towards a big AI crash like the dot-com crisis? Here's what European Central Bank predicts

The European Central Bank warns that an AI market correction on Wall Street is likely, citing historical tech bubbles like the dot-com era. Even if AI succeeds, overstretched valuations, shifting macro risks, and limited policy buffers could trigger sharp stock adjustments, impacting euro area investors. Amid the rising exuberance around artificial intelligence, European Central Bank feels that a market correction on Wall Street is likely and could have far-reaching consequences due to limits in fiscal and monetary policy buffers to blunt the potential economic hit. In a blog post titled 'The AI boom: rational enthusiasm or the next dot-com bubble?', ECB highlighted that the rise of artificial intelligence has driven a blistering rally in the tech sector, bringing valuations in the stock market to levels last seen during the dot-com bubble. "The extremely optimistic valuations raise questions: do today's stock market prices reflect a rational bet on the transformative technology? Or are we seeing a remake of the dot-com bubble? We argue that economic research on past technological revolutions points to a worrisome conclusion: a correction of current stock market valuations is likely," European Central Bank said. It added that a sharp stock market correction would have severe consequences for Europe through two channels - investors' direct exposure to the Magnificent Seven stocks and the degree of overexuberance in euro area stock markets themselves. Similar frenzies in history ECB noted that the ongoing frenzy around AI has many historical precedents - the railway boom of the 19th century, the expansion of electricity and radio in the 1920s and the surge of the internet, or the "dot-com era", in the 1990s. "In each case, a genuinely transformative technology attracted investment, and the stock market valuations of firms that adopted it rose strongly before falling sharply," it highlighted. Even if artificial intelligence succeeds and meets investor expectations, the stock prices still may eventually fall, according to the ECB, which believes that this will be driven by the nature of uncertainty shifting from a "single sector" to the "entire" economy. Even if the technology succeeds and profits rise, stocks may still fall because it is hard to fulfil markets' excessively optimistic profit growth bets, the blog post added, noting that overly optimistic investors tend to bid up prices beyond fundamentals. Then when optimism fades, prices tend to fall even more sharply than in the rational scenario.

The increased optimism sparked a sharp rally in the AI stocks, before things began to go down. Analysts soon began sounding the alarm over the massive AI spending and rising debt of the tech giants, questioning if they will actually bear fruit in the future. The worries sparked a sharp selloff in the tech stocks, although they have begun to rebound. Earlier this year, Michael Burry, famous for correctly predicting the 2008 financial crisis, wrote on a Substack post that he sees many indicators, both technical and fundamental, lining up for the same conclusion as the dot-com crash. "1999 went where no market had gone before, and I would say so can this one...It is already there on a number of indicators," he said, arguing that massive venture capital flows, rising AI debt issuance, and extreme market optimism are creating conditions where valuations may detach from economic reality.

Scary Thought: European Central Bank Warns That the AI Bubble Could Burst Soon

The bank believes that while Europe itself may have no role to play in the current AI ecosystem, a boom or a bust will impact its retail investors big time While the proponents and critics of the AI ecosystem continue to debate on its future amidst growing concerns over datacentres and the rising costs to enterprises, there is a section of the population that is concerned that the impact will have ramifications way beyond Silicon Valley which is nurturing it and the Wall Street that is doing the valuations. Earlier this week, the European Central Bank cautioned the world that a market correction is not just highly probable but could potentially have far-reaching consequences around the world, especially in Europe. The rise of AI has driven a blistering rally in the tech sector, bringing stock market valuations to levels last seen during the dot-com bubble. Although AI is reshaping the economy, do today's high valuations bear the risk of an abrupt and painful setback in the euro area?" the Bank says in a recent blog post. The article, authored by ECB economists and financial researchers Malin Andersson, Johannes Breckenfelder, Stefano Corradin, Kalin Nikolov and Maria Antonietta Viola, refers to two explanations of the AI financial bubble. Dubbed the "rational view", the first notes that the unprecedented tech investments are justified by "extreme uncertainty" over a new technology's impact on productivity. They note that Nvidia's valuation swelled beyond $5 trillion in October last year over the expectations that there would be some quantitative leap in AI's abilities. In such a scenario, Nvidia becomes the "pick and shovel" salesman to the AI industry's gold rush while in the worst case scenario, investors lose their investments. "But in the best case, the gains are large and genuinely hard to bound. This 'option value' increases the stock valuations of early adopters, causing their price-to-earnings ratios to rise sharply," the authors of the article say while also adding a second explanation that they call the "behavioural view." In this scenario, they note that investors are essentially "overconfident" and "overoptimistic" over the technology and could essentially be losing themselves to the hype, often ignoring the rational possibility of either a devastating financial loss or an unprecedented gain, because they essentially follow a "live-for-the-moment" playbook. The question that the authors put is what happens when this kind of overconfidence around new technology recedes or fades away? Losses and a market correction could be swift, severe and extremely decisive, they warn while noting that as on date there is an unholy blend of both scenarios playing out in the markets. They caution that both scenarios "imply a boom followed by a correction, or a pullback from wherever valuations have risen, at some point in the future." As for how things may pan out in Europe, the report asserts that it is hard to tell given the limited information being made available by the AI labs in general. Coming to the impact that the AI boom or bust cycle will have on European markets, the authors note that a "sharp stock market correction would have severe consequences for the euro area, through two channels. One is euro area investors' direct exposure to the Magnificent Seven stocks (hereafter Mag7) and the other is the degree of overexuberance in euro area stock markets themselves." This Mag7 dominance on global indices carries significant risks for the euro area investors since most of their exposure are via investment funds such as mutual funds and ETFs rather than through direct holdings. With euro-area households increasingly channelling funds into low-cost ETFs, the current exposure levels stand at around Euros 440 billion. And investors aren't necessarily aware of the associated concentration risks. Such a fund-based structure itself is a transmission channel and a sharp correction can force funds to sell for meeting redemptions. The process could start with liquid holdings and in case the correction continues go to distressed assets, thus pushing valuations down further and triggering more redemptions. "This is why a Mag7 correction is a question of financial stability for the euro area, rather than just a private one. The more severe scenario is not the equity correction on its own but a correction that coincides with broader market instability that policymakers cannot easily calm: unlike in the dot-com episode, today's starting point leaves markedly less room to cut interest rates or use fiscal policy to cushion the fallout," the blog warns. The only thing that can be said with some surety is that the spark that could light a fire under the bubble would not emerge from the European markets. European "households, insurers and pension funds have significant exposures through global index trackers." However, the effects of a US correction could extend beyond financial markets to euro area sentiment, financing conditions and hiring. But, "A US AI fallout would not remain a US problem."
