The European Central Bank warned that US technology stocks lifted by the AI boom may be vulnerable to a meaningful valuation correction, with fallout that could prove hard to cushion. In an article, the ECB said investors have continued to add exposure on expectations that AI will reshape the global economy, pushing major tech company valuations well above historical averages. It added that research on past major technological revolutions points to a high probability of a market correction. The ECB also said that even if AI ultimately succeeds and corporate profits rise, stock prices could still fall because current market expectations for earnings growth may already be too optimistic. The article noted that overly bullish investor sentiment can drive prices beyond levels supported by fundamentals, and that any retreat could be deeper than a purely rational repricing. It further warned that, compared with the early-2000s dot-com period, policymakers now have less room to cut rates and less fiscal capacity to soften any downturn. The timing of a correction, the ECB said, cannot be known in advance.

A summer heatwave could erase about 1% of the European Union’s 2026 GDP, or roughly €180 billion, according to estimates cited from Dutch bank Triodos Bank. The report says the biggest hit comes from weaker labor productivity as extreme heat cuts working hours and halts activity in outdoor construction and logistics. France is seen as the hardest-hit economy, with GDP potentially reduced by 1.4% and full-year growth turning into a 0.6% contraction, while the Netherlands could see growth nearly stall. Triodos breaks the damage into four channels: labor losses, tighter food supply and lower dairy output, power disruptions and higher electricity prices, plus transport bottlenecks across land and inland waterways. The report also points to low water levels in rivers including the Seine, Rhine and Danube, pressure on nuclear generation, and weaker crop output for corn and sunflower. Analysts cited in the piece say these are supply-side shocks that conventional rate cuts or fiscal stimulus cannot easily offset. The article also highlights inflation risks for the European Central Bank, wildfire losses, heat-related excess deaths, and a possible shift in summer tourism from southern Europe to cooler northern destinations. Triodos chief economist Hans Stegeman warned that climate damage is no longer a distant economic risk and argued that cutting the cost requires slowing climate change itself.

A European Central Bank survey of 8,205 companies across the euro area found that crypto adoption in day-to-day business payments remains extremely limited. Only 0.2% of surveyed firms said they accept cryptocurrencies or stablecoins for online payments, while the acceptance rate at physical points of sale stood at 1%. The survey also showed that traditional payment methods still dominate among businesses with physical sales locations. Cash was accepted by 92% of those firms, and 88% accepted card payments. At the same time, mobile payment acceptance rose sharply, increasing from 36% in 2024 to 68% in 2026. The figures were cited by Odaily, which referenced Bitcoin.com News as the source.

A dense 24-hour news cycle brought fresh filings, earnings, market calls and regulatory signals across crypto and adjacent tech markets. Fidelity filed an amended registration statement with the U.S. Securities and Exchange Commission on Aug. 11 to add ETH staking to its spot Ethereum ETF, the Fidelity Ethereum Fund (FETH). Under normal conditions, the fund said it could stake as much as 100% of the ETH it holds, with no minimum staking threshold, and its investment objective would change to include staking rewards if approved. Elsewhere, some existing Anthropic investors said the AI company could be valued at more than $2 trillion if it goes public as early as October, with one investor putting the upside case at $3 trillion based on a roughly 30x revenue multiple. The estimates remain investor forecasts, and several investors said Anthropic management has not set an IPO valuation target. The session also featured quarterly updates from Bullish, BitGo and Securitize, new SEC steps around tokenized fund operations and tokenized equities, ETF flow data for Bitcoin and Ethereum products, and a series of policy, infrastructure and security developments spanning Europe, the U.K., Brazil and the U.S.

Andre Cronje, the creator of Fantom and founder of Flying Tulip, said on Cointelegraph’s Chain Reaction X Spaces that DeFi, outside of a very small niche, no longer exists. In his view, a protocol only qualifies as true DeFi if it is decentralized, immutable and free of intermediaries, a standard he said very few live systems now meet. Instead, he argued, the sector has shifted into what he calls onchain finance or open finance, where companies, decision-makers, vault curators and risk committees have taken over roles once associated with traditional banking. The report ties that argument to recent market structure and governance data. It notes that curator-led lending vaults now direct capital allocation and risk settings while depositors absorb tail risk, and points to the November 2025 collapse of Stream Finance, which hit three lending platforms and pushed utilization on multiple Morpho and Euler vaults to 100%. It also cites a March 26 working paper from the European Central Bank that found the top 100 governance token holders controlled more than 80% of supply in Aave, MakerDAO, Ampleforth and Uniswap. Separately, DefiLlama data showed DeFi total value locked fell from $167.1 billion on Oct. 8, 2025 to $75.1 billion at the time of writing, a 55% drop over 10 months.

A Reuters poll shows 83% of economists expect the European Central Bank to raise its deposit facility rate by 25 basis points to 2.50% in September. Nomura warns that prolonged high oil prices raise second-round effect risks, and argues a single hike would look like a fine-tuning operation, making another move highly likely.

Citi strategist David Chew said European equities are currently the only major market region where risk appetite has shown a clear improvement, according to Jin10, as cited by ChainCatcher. He attributed the shift to fresh fund inflows and corporate earnings that came in better than expected. The report said positioning sentiment improved across all major European stock indexes last week. In contrast, comparable indicators for the U.S. market pointed to weaker investor confidence. Chew also said European markets benefited from the European Central Bank’s decision to leave interest rates unchanged. The comments point to a widening gap in near-term sentiment between Europe and the U.S., with Europe standing out among major regions in the latest reading.

According to a Jin10 report cited by ChainCatcher, the European Central Bank said in its economic bulletin released Monday that household consumption in the euro area fell sharply after the outbreak of the Iran war, with the drop mainly tied to a steep deterioration in consumer confidence. In April this year, the decline in consumption reached twice the level implied by historical trend forecasts, and the scale of the impact was comparable to the response seen after the outbreak of the Russia-Ukraine conflict in early 2022. The bulletin said nominal consumption growth in the euro area had averaged around 3% to 4% since mid-2024, but slowed to about 2.5% year over year in April. The slowdown was driven mainly by higher-income households cutting non-essential spending.
