彭博全球長債指數收益率已升至約4.2%，創2008年7月以來最高。 該指數反映一籃子長期投資級債券的二級市場定價，並不等於各國政府全部債務立即按4.2%再融資。壓力在於“高利率持續多久”。OECD經濟體主權債務2025年已達61萬億美元，2026年融資需求預計升至18萬億美元；隨着低息舊債陸續到期，高收益率纔會逐步轉化爲更高付息成本，並通過“利息上升—赤字擴大—發債增加—期限溢價擡升”形成反饋。 目前國債拍賣仍能消化發行，債券及回購市場流動性總體正常，若後續出現拍賣持續尾部、交易商被迫大量承接或回購融資異常，才意味着壓力向真正的債市危機升級。

Saudi Arabia is offering cargoes loaded off the coast of Oman, suggesting it may be following the UAE in routing more oil via transshipment rather than conventional Strait of Hormuz shipments. Sources say Aramco is supplying ship‑to‑ship cargoes loaded at Gulf of Oman ports such as Sohar. The cargoes are Arab Medium and Heavy grades, pointing to Persian Gulf origin. In March Aramco CEO Amin Nasser said the Yanbu pipeline mainly carries Arab Light and Extra Light, while near‑shore Persian Gulf fields supply the kingdom’s medium and heavy barrels. Aramco declined to comment.

Following earlier new-account rules requiring confirmation that funds originate from lawful offshore channels, some Hong Kong banks have begun seeking source-of-funds declarations from selected existing mainland China investment clients. HSBC Hong Kong has told affected clients to submit an Account Opening/Maintenance declaration via the HSBC Hong Kong app and update contact details by Sept 12. The declaration requires confirmation that investment funds come from lawful sources outside mainland China and notes the bank may disclose personal data to law enforcement or regulators. The notice warns that failure to submit by Aug 20 may result in suspension of investment services, and failure to submit by Sept 12 could lead to termination. An HSBC spokesperson on Aug 18 said the bank is following regulatory requirements and is asking affected mainland investors to self-declare and confirm their KYC and client due-diligence information is current; the requirement applies only to investment-service clients.
