On October 21, the two companies announced that in the coming weeks, OpenAI will offer its cutting-edge AI models and Codex code intelligence services through Google Cloud. This move deepens the collaboration between these two competitors and highlights how major cloud service providers are becoming important distribution channels for top AI models. According to a corporate blog announcement, this partnership will integrate OpenAI's latest models, including GPT-6 Astra, into Google Cloud's Model Garden. Customers will be able to purchase these models on the Google Cloud Marketplace and settle using their existing cloud service procurement credits. OpenAI aims to promote its models to a broader range of enterprise customers.

On October 21, CME Group announced its intention to collaborate with AI index startup Silicon Data to launch a tradable product based on AI model Token expenditures. The product will be based on its large language model (LLM) Token index, which will weight the Token prices of different AI models according to usage. Carmen Li, CEO of Silicon Data, stated that while the market has a good understanding of GPU computing costs, there is still a lack of awareness regarding the consumption layer of the AI economy. In August of this year, the two parties announced plans to launch a futures product based on GPU leasing costs. Silicon Data indicated that the new Token index product is expected to be launched in the coming months, pending regulatory approval. The LLM Token expenditure index released by the company is currently hovering near its lowest point since its launch in December last year, following a decline over the summer, which may reflect users shifting from high-end models to more affordable alternatives.

The Office of the Comptroller of the Currency (OCC) released the final rules for the implementation of the GENIUS Act on Wednesday, becoming the first regulatory agency to complete the formulation of stablecoin regulatory rules under this act. The new rules will take effect on January 18, 2027. The regulations establish a framework for approved stablecoin issuers and provide a pathway for both banking and non-banking institutions to conduct stablecoin payment operations, while also clarifying standards for foreign stablecoin issuers and asset custody. The final rules require stablecoin issuance regulation to adhere to standards such as reserve support, redemption, and risk management. Unlike previous proposals, the new rules do not include presumptive violation clauses related to specific business relationships between issuers and third parties. However, regulatory officials stated that the OCC will still assess relevant arrangements on a case-by-case basis and has the authority to take enforcement action against behaviors that evade the requirements of the act. The issue of stablecoin rewards has previously become a contentious point between the U.S. banking industry and the cryptocurrency sector, with banks concerned that such rewards could lead to deposit outflows, although the GENIUS Act does not fully prohibit platforms from offering rewards to users.

On October 21, according to Yonhap News Agency, SK Hynix's large-scale share buyback, following that of Samsung Electronics, also concluded on the 21st. SK Hynix announced that it completed a two-month share buyback worth 40 trillion won (approximately 30.213 billion USD) on the Korea Securities Exchange (KOSPI) on that day. Previously, SK Hynix had declared an investment of 40.0434 trillion won to repurchase 24.07 million shares of the company, with all shares to be canceled after the buyback is completed. This buyback represents about 3.3% of the company's total issued shares and is the largest share cancellation operation by a listed company in South Korea. The originally announced buyback period was from August 20 to November 19, but the actual buyback was completed approximately one month ahead of schedule.

On October 21, the UK government's borrowing in the first six months of this fiscal year exceeded expectations, highlighting the constraints faced by Chancellor of the Exchequer Jeremy Hunt ahead of his first budget announcement next week. From April to September, the UK's fiscal deficit widened to £97.8 billion (approximately $130 billion), which is £6 billion higher than the forecast made by the Office for Budget Responsibility (OBR) in March. In September, government borrowing reached £24.5 billion, surpassing both the OBR's predictions and the levels from the same period last year. This set of data reflects the latest state of public finances ahead of the budget announcement on October 28, where Hunt must outline the policy direction for Prime Minister Rishi Sunak's new government while avoiding panic in the bond market, as concerns grow over the high level of UK government debt. The total UK government debt has now exceeded £3 trillion for the first time. Despite the UK economy demonstrating strong resilience against energy shocks caused by the Middle East conflict and tax revenues exceeding OBR forecasts, government borrowing has still been higher than expected for the fiscal year 2025 to 2026 so far.

On October 21, a key crude oil benchmark in the Middle East dropped to its lowest level in nearly three months, indicating that despite escalating attacks on shipping by Iran, the region's oil exports are showing strong resilience. According to General Index data, this week, the premium of Oman crude over Dubai crude fell to around $4 per barrel, the lowest level since late July. This price difference reflects the strength of the physical crude oil market in the Gulf region. In the early stages of the conflict, this premium soared to over $60 per barrel as the Strait of Hormuz was nearly closed. Despite the risk of attacks, major oil-exporting countries in the Middle East have successfully allowed more tankers to pass through the waterway or completely bypassed the Strait of Hormuz via pipelines. These efforts have weakened Iran's attempts to leverage its position by disrupting global energy flows.

On October 21, the South Korean KOSPI index closed up 182.93 points, an increase of 3.29%, reaching 5735.67 points. Samsung Electronics rose by 5.67%, while SK Hynix increased by 5.8%.
