According to The New York Times, the market generally expects the Federal Reserve to maintain interest rates at the FOMC meeting this week (October 27 to 28). Federal Reserve Chairman Kevin Walsh needs to explain why he is not raising interest rates while inflationary pressures remain high, while also indicating that the determination to combat inflation has not weakened and keeping the possibility of another rate hike this year.The report states that the Federal Reserve raised rates once in September, and the market had once priced in another rate hike in October. New York Fed President John Williams, Vice President Jefferson, and Governor Waller expressed at the end of September to early October that they could wait a bit longer, causing the probability of an October rate hike to drop from over 70% to less than 30%. High oil prices and the demand for materials and electricity driven by AI infrastructure increased price pressures in September. The Nasdaq 100 index has fallen more than 7% since its historical high on October 6, and the yield on the 10-year U.S. Treasury bond had previously stood above 5% for several consecutive weeks.Stephen Stanley, Chief Economist at Santander U.S. Capital Markets, stated that he expects interest rates to remain unchanged this week but believes there may still be another rate hike in December. Walsh needs to explain why he is not taking action in October while also clarifying why December is still under consideration. Since taking office in May, Walsh has provided little forward guidance on the interest rate path. The press conference after the decision to hold rates steady in July caused market volatility due to overly brief wording, and subsequent hawkish remarks in August, along with the rate hike in September and signals of another hike this year, somewhat repaired communication. This week's decision is approaching the U.S. midterm elections on November 3, and Trump had previously criticized the rate hike in September.

Goldman Sachs' latest research shows that over the past three weeks, semiconductor stock exposure has been able to explain about 54% of the return performance differences between different asset classes, while oil price exposure accounts for only 2%. As the influence of AI trading continues to expand, technology stocks are becoming an important factor driving global market risk appetite and asset performance differentiation.Goldman Sachs pointed out that recent investor risk appetite has been highly synchronized with the relative performance of large technology stocks. Last week, concerns about AI investment returns, financing costs, and capital expenditures intensified, leading to a sell-off in technology stocks and corporate bonds, with Goldman Sachs' risk appetite indicator falling to its lowest level since April 2025. The South Korean stock market has become a typical case of this impact, with the KOSPI rising 3.1% on Tuesday, and SK Hynix and Samsung Electronics increasing by 5.2% and 4.2%, respectively.Due to the high weight of semiconductor stocks in the Korea Composite Stock Price Index, changes in global AI investment expectations directly affect local market performance. Goldman Sachs emphasized that the 54% and 2% figures reflect a statistical relationship within a specific time window and do not imply that AI factors long-term determine global market fluctuations; the impact of high oil prices on inflation, monetary policy, and asset pricing cannot be ignored. Major technology companies such as Microsoft, Google, and Amazon are about to announce their earnings reports, and the market will focus on whether AI demand can continue to grow and whether massive capital expenditures can be converted into actual profits.

According to The Block, BlackRock Financial Management, BlackRock Japan, and Japan's financial group SBI Holdings, along with Startale Group, have signed a memorandum of understanding to explore connecting tokenized money market funds with the yen stablecoin JPYSC, and to study the related technological infrastructure, business models, distribution channels, and regulatory requirements.The four companies stated that the collaboration aims to promote interoperability between tokenized assets and stablecoins, and to open up cooperation opportunities for financial institutions and businesses in Japan and internationally.

According to Bitcoin News, researchers claim that Tailscale has a serious vulnerability, where users with approved access can exploit its built-in SSH to gain root access to devices, and the attack may spread to other devices on the network.Users running nodes with Tailscale should disable Tailscale SSH and update promptly after the patch is released. Tailscale has not yet responded.

According to BlockSec monitoring, a suspicious transaction by X100 Global on Ethereum resulted in a loss of approximately 4.75 million USD, with the related attack stemming from a vulnerability in the governance mechanism design: the attacker used a flash loan to borrow funds to purchase X tokens, allocated the tokens to two controlled contracts, and then deposited them into the Freezer, thereby controlling 2 out of 3 senator seats in the same transaction, and subsequently immediately passed and executed a malicious treasury proposal.Specifically, the attacker first created and provided liquidity to the X-USDT trading pool on PancakeSwap V3, then used the obtained majority governance seats to approve the exchange of 400,000 X tokens into that trading pool, setting the minimum output amount to 0, ultimately receiving only about 35.68 USDT. Subsequently, the attacker withdrew liquidity, sold part of the recovered X tokens through the existing Uniswap V3 X-USDT trading pool, and repaid the flash loan.

According to Slow Fog's Yu Xian monitoring, users should promptly update their iPhone and iPad systems and be vigilant about certain installed apps being poisoned by DarkSword.DarkSword mainly targets iPhone cryptocurrency users for pinpoint attacks and coin theft, exploiting iOS-related vulnerabilities to break through the sandbox and steal various passwords and other private data from the Keychain, as well as local wallet private key files, memos, and other private data.

Bitcoin core developer Antoine Poinsot announced an adjustment to the security vulnerability disclosure policy in the Bitcoin development mailing list. He stated that in the past, vulnerabilities were often kept secret for a long time to allow users to complete upgrades before details were made public, but this also led to fixes not being backported to older versions, requiring users to wait for the next major release. Poinsot pointed out that large language models make some vulnerabilities very easy to rediscover, and the protection that continued delays in fixing can provide is now quite limited.According to the new policy, vulnerabilities deemed "easy to discover" will be fixed as soon as possible in all maintained major versions, with security announcements released simultaneously. This classification applies to vulnerabilities that can be discovered with minimal effort, such as through simple LLM prompts. Other vulnerabilities will still follow the disclosure timeline based on severity: low-severity vulnerabilities will be disclosed two weeks after the major release containing the fix; medium to high-severity vulnerabilities will be disclosed two weeks after the last affected version reaches its end of life (usually one year after the fix is released in a new major version). Critical vulnerabilities are not covered by the standard policy and may require ad hoc procedures.Bitcoin ecosystem security researcher Luke de Wolf stated that he previously disagreed with Poinsot's security strategy but believes this update is a good adjustment. In August of this year, the volunteer-based Bitcoin Red Team reported nearly 5,000 potential issues across 390 projects, with only about one-fifth being reproducible at that time. In the same month, Core Lightning developers urged operators to upgrade or take nodes offline after receiving multiple AI-generated vulnerability reports, while keeping technical details confidential for two weeks.

According to CoinDesk, Shinhan Card, a subsidiary of South Korea's Shinhan Financial Group, is collaborating with a subsidiary of Japan's SBI Holdings to explore the payment applications of a yen stablecoin between the two countries. Participants include the cryptocurrency exchange SBI VC Trade and the trade finance blockchain company SBI XDC Network APAC.The collaboration will study scenarios such as card-linked merchant payments for Japanese tourists visiting South Korea, wallet-to-wallet transfers, and cross-border trade settlements, and will include suspicious transaction monitoring and anti-money laundering compliance systems.

JPYSC is currently only available for use in SBI VC Trade accounts and cannot be transferred to external wallets. Its circulation on the public chain depends on legal and tax clarity and regulatory approval, and the parties have not indicated whether JPYSC will be included in this test.
