Valuations of OpenAI and Anthropic have fueled venture-capital fears of a startup correction, Bloomberg reported. In late September, OpenAI began discussions for its latest funding round, seeking at least $30 billion in new capital at a $1.4 trillion valuation. The company had previously been valued at $852 billion. Some investors considered the terms too lofty, according to people familiar with the matter.

Diamond prices are about 70% below their 2011 all-time high and have reached their lowest level this century. The Bloomberg Diamond Standard Index, cited by Barchart, stands at 2,500, down from about 8,450 in 2011, and has broken a floor near 4,700 that held from 2005 to 2020, according to BeInCrypto. The IDEX polished diamond index has nearly halved since March 2022, from about 158 to around 80, while the U.S. diamond import price index was 97.6 in September, below its 2000 baseline of 100. Prices vary by stone: IDEX’s sub-index for 1-carat round diamonds is about 61, compared with roughly 149 for 5-carat emerald cuts. Lab-grown stones accounted for 61% of U.S. engagement rings in 2025, and a certified 1-carat lab-grown diamond sells wholesale for under $90. Other pressures include the unwinding of record sales in 2021 and early 2022, inflation, tighter consumer finances and falling demand in mainland China. De Beers sold 71% more rough carats in the third quarter after cutting prices in July; its average price fell 45% to $84 per carat. Gold has dropped 31% from its January record. A 50% U.S. tariff on Indian goods imposed in 2025 hit a major diamond-cutting center; India’s gem and jewelry exports to the U.S. fell 44% before the rate dropped to 18%. Anglo American paid nearly $13 billion for the Oppenheimer family’s De Beers stake in 2011 and is now reportedly selling its holding for about $1 billion. On November 9, Botswana’s president backed a consortium led by former De Beers CEO Gareth Penny. De Beers says large, high-quality stones remain in demand, while 1-carat diamonds face price competition from lab-grown supply.

The collapse of Paraguay’s digital lender Ueno Bank left nearly three million customers, roughly 60% of the country’s adults, unable to access their accounts last week. According to Cointelegraph, the Central Bank placed Ueno into resolution on Nov. 3 after its solvency ratio fell below half the legal minimum, with an investigation citing questionable lending and deficiencies in credit documentation and accounting. The failure fueled protests and a political crisis involving President Santiago Peña. Paraguay’s peer-to-peer crypto market quickly reflected the turmoil, with some sellers seeking premiums of up to 13% for USDt. As the guaraní fell 12.3% in a week, customers turned to dollar-pegged stablecoins to preserve savings and keep payments moving. X4T founder and CEO David Eisenmann said the intervention came when salaries, rent and supplier invoices were due, leaving some business owners unable to make payroll. X4T processed more than $10 million in local on-ramp volume over the 30 days to early November, although some activity predated Ueno’s collapse. Eisenmann said demand for USDt and USDC rose, while customers also sold crypto to cover payments. By Nov. 9, the Central Bank said 93.1% of depositors had been repaid, but X4T continued to receive elevated inquiries about dollar-denominated stablecoins. Analysts said the episode highlighted stablecoins’ potential to provide liquidity when confidence in banks falters, but cautioned against treating them as a risk-free substitute. GlobalData associate analyst Rhys Hicks said there was no evidence of a mass shift from Paraguayan banks into stablecoins, noting other banks had picked up the slack and consumers appeared more angered by the government. He said stablecoins may appeal during political instability because they are pegged to a comparatively stable currency, such as the U.S. dollar, but holders lack bank deposit guarantees and a central bank backstop. Stablecoins are also connected to the traditional financial system: during Silicon Valley Bank’s collapse in March 2023, Circle disclosed that $3.3 billion of USDC reserves were held at the lender. USDC briefly fell to 86 cents after Circle said it could not withdraw the funds. A BIS paper has also warned that widespread adoption of dollar-backed tokens could challenge monetary sovereignty in emerging markets. Eisenmann expects people to diversify across banks, cash and digital assets. He said the speed of restoring trust will depend on how quickly and transparently authorities handle Ueno’s resolution.

According to ChainCatcher citing Bitcoin Magazine, former U.S. Commodity Futures Trading Commission (CFTC) Chair Chris Giancarlo said the debate over crypto market-structure legislation is increasingly about jurisdiction rather than sound regulation. He said the Securities and Exchange Commission (SEC) and CFTC have clarified their respective oversight areas and are cooperating smoothly. Giancarlo also said that with Democrats controlling both chambers of Congress, the direction of Bitcoin and crypto regulation will face renewed political contest. He pointed to the Depository Trust & Clearing Corporation’s progress on tokenized collateral as evidence that Wall Street is moving toward digital-network finance regardless of policy changes in Washington. The interview also covered stablecoin regulation, oversight of prediction markets and perpetual futures, and central bank digital currencies.
