What happened

Chinese AI startup DeepSeek released DeepSeek-V4.1-Flash-1017 on Saturday, October 17, an update to the V4.1-Flash model launched September 10. DeepSeek calls it a Pareto improvement: faster task completion, shorter outputs, and better benchmark scores, with open weights published on Hugging Face under an MIT license. On its own benchmarks it scored 77.0 on the DeepSWE v1.1 coding test, up from 74.2 for the prior version and ahead of Anthropic's Claude Opus 5 (74.0) and OpenAI's GPT-5.6 Sol (73.0), at an effective cost under $0.20 per task versus $2 to more than $10 for U.S. rivals. DeepSeek also opened its in-house search engine to outside developers via Search and Fetch APIs. None of the benchmark figures have been independently verified, and Hugging Face co-founder Thomas Wolf publicly questioned whether the scores will hold up outside DeepSeek's own evaluation environment.

What happened

Russian President Vladimir Putin has proposed that he, President Trump, and Chinese leader Xi Jinping meet next month to discuss ending the war in Ukraine, the Wall Street Journal reported Sunday, citing people familiar with the discussions. Putin floated the idea in an Oct. 9 phone call with Trump, and the Kremlin has suggested holding the talks on the sidelines of the APEC summit on Nov. 18-19 in Shenzhen. Kremlin spokesman Dmitry Peskov confirmed discussions are taking place, while a senior U.S. official said Trump has not agreed to the summit but could be receptive. The proposal would exclude Ukrainian President Zelensky — a format the Journal notes would be unprecedented and would alarm European allies.

What happened

Bank of Japan Governor Kazuo Ueda told parliament on Monday that underlying inflation is "quite close" to the BOJ's 2% target, and said it is becoming more important to anchor inflation around that level. Ueda cited a tight job market, a moderate economic recovery, and "very strong" global AI demand boosting capex and exports as sources of price pressure, alongside rising raw-material costs from the Middle East conflict. He warned that failing to adjust the policy rate at an appropriate pace could push long-term bond yields higher by stoking concern over an inflation overshoot.

What happened

Apple's first foldable iPhone, the $1,999 iPhone Duo, built a long preorder backlog within minutes of orders opening on Oct. 16, with delivery estimates slipping into January 2027 ahead of the device's Oct. 23 release. Evercore ISI viewed the roughly 100-day waiting period as a positive sign that demand has started strongly. Bloomberg Intelligence analysts suggested sales could exceed their earlier fiscal 2027 estimate of 14 million units and $28 billion in revenue. Apple stock rose about 2% over the week.

What happened

A third oil tanker in three days struck a naval mine in the Strait of Hormuz on Sunday evening, triggering an explosion and fire in its engine room, according to a statement from Iran's Islamic Revolutionary Guard Corps (IRGC) Navy released early Monday. The vessel had switched off its positioning and navigation systems and was using what Tehran calls an unauthorized southern route. On Saturday, the IRGC Navy said two supertankers — each carrying about 2 million barrels of crude — caught fire after hitting mines while attempting to cross via unauthorized routes. Separately, the U.K. Maritime Trade Operations (UKMTO) reported a tanker attacked with a rocket-propelled grenade from a small boat off Saudi Arabia on Friday. There has been no independent confirmation of the Iranian claims, and vessel identities and crew fates were not disclosed.

China's economy grew 4.5% year on year in Q3 2026, beating the 4.4% consensus forecast and accelerating from 4.3% in Q2, according to data released Monday by the National Bureau of Statistics. On a quarterly basis, GDP rose 1.2%, ahead of the 1.1% expected. September activity data also beat: retail sales rose 1.1% year on year — more than double August's 0.4% and the fastest since March — while industrial production grew 5.5%, its fastest in six months. Growth for the first nine months of 2026 was 4.6%, within Beijing's 4.5%-5.0% annual target range.

What happened

U.S. Treasury Secretary Scott Bessent said Sunday that Washington and Beijing reached a 'very substantial framework' in high-level talks in Kuala Lumpur that averts the threatened 100% additional U.S. tariffs on Chinese goods. Bessent said he expects China to delay implementation of its rare-earth minerals and magnets export-control licensing regime by a year while the policy is reconsidered, and that the tariff truce expiring November 10 will be extended pending the president's decision. China is also expected to revive substantial purchases of U.S. soybeans after buying none in September, and the framework covers more balanced trade, fentanyl, and export controls. Bessent told NBC's 'Meet the Press': 'No, I'm not [anticipating the 100% tariffs], and I'm also anticipating that we will get some kind of a deferral on the rare earth export controls.'
