According to CNBC, tensions between Iran and the U.S. over control of the Strait of Hormuz continue to escalate. Ali Ozmaei, head of Iran's Islamic Revolutionary Guard Corps (IRGC), said Iran is waiting for an opportunity to attack U.S. warships, and threatened that if the U.S. believes the strait is open, it can approach further. U.S. Central Command (CENTCOM) responded that U.S. military forces and regional partners remain firmly in control of the key waterway. Shipping security risks have risen in tandem. A Singapore-flagged container ship, the GFS Pride, sank after being attacked in the Strait of Hormuz; all crew members were evacuated with no injuries. Another Singapore-flagged vessel, the GFS Giselle, was also attacked, sustained hull damage, and later reached a safe anchorage. Singapore's Maritime and Port Authority (MPA) condemned the attacks as unprovoked, unjustified, and in violation of international law.

Affected by the inflation data, the S&P 500 fell 1.11%, the Nasdaq Composite dropped 1.88%, and South Korea's Kospi index plunged 7.26%. Analysts note that Trump's temporary relaxation of restrictions on Russian diesel exports may have limited impact on easing energy inflation.

Dongcha Beating AI News: Google has begun sending notifications to Google AI Plus subscribers, confirming that starting November 13, AI Plus users will no longer be able to manually select Pro-series models in the Gemini app and Google Search’s AI mode, with only Flash and Flash-Lite available for selection. Chat history from prior Pro model usage will not be deleted, though users must switch models to continue their conversations. This adjustment was announced as early as early October. On October 3, Google updated its help documentation, specifying that free users would lose the ability to manually select Flash and Pro models starting October 9, while AI Plus would also remove Pro model selection access—no specific effective date was shared at that time. In the U.S. market, Google AI Plus is priced at $4.99 per month. To retain manual Pro model selection, users must upgrade to AI Pro, which costs $19.99 monthly—four times the original subscription fee. Google’s newly launched flagship model, Gemini 4 Argon, is exclusively available to AI Pro and Ultra subscribers.
