美联储點陣圖 7:7 分裂,鮑威爾說通脹進展不如預期,同時拒絕在調查結束前離開。利率沒有變動,但鷹派信號在收緊。


1|美联储點陣圖撕裂,鮑威爾的最後兩場記者會變成了政治生存戰

美聯儲週三維持利率 3.5%-3.75% 不變,這在預期之內。超出預期的是點陣圖,19 名委員中 7 人認為 2026 年不應降息,比 12 月多了 1 人,另外 7 人預期只降一次。通脹預測從 2.5% 上修至 2.7%。鮑威爾的措辭比市場想聽到的更冷,「我們預測通脹會有進展,但不如我們希望的那麼多。」美股盤中跌至日內低點。

同一場記者會上,鮑威爾宣布他不會在任期到期前離開。美國檢察官 Jeanine Pirro 正在調查美聯儲總部翻新項目,特朗普提名的繼任者 Kevin Warsh 被參議員 Tillis 在銀行委員會搁置。鮑威爾任期 5 月 15 日結束,但他說「無意在調查徹底結束前離開」。表面是一場利率決議,底層是美聯儲主席的去留正在被一桩裝修調查和一個參議員的否決權同時綁架。

2|英偉達 GTC 四天畫完帝國版圖,Groq 收購變成了推理武器

GTC 第四天,英偉達把 2025 年 12 月花 200 億美元收購的 Groq 變成了產品。Groq 3 LPX 平台由 128 顆 LPU 組成,與 Vera Rubin NVL72 聯合部署聲稱每兆瓦吞吐量提升 35 倍。同日發布的 Vera CPU 是首款專為 Agentic AI 設計的處理器,效率是傳統機架級 CPU 的兩倍。

週一講七芯片平台,週二講推理網格(AI Grid),週三講開源聯盟(Nemotron Coalition),週四講 Groq 推理和太空數據中心(Space-1)。四天下來,黃仁勳建設的不是一條產品線,是一張從地面到軌道、從訓練到推理的算力帝國版圖。下一代 Feynman 架構也已公佈,包括 Rosa CPU、LP40 LPU、BlueField-5 和 Kyber 網路。

3|150 Retired Judges Jointly Support Anthropic, Pentagon Counters with "Hostility"

Last night reported the DOJ's 40-page document and Anthropic's corporate market share overtaking OpenAI's data. Today's incremental update is a collective statement from the legal community. Nearly 150 retired federal and state judges submitted an amicus brief to the court, questioning the legality of the Pentagon's use of the "supply chain risk" label on Anthropic. In addition to the previously stated four major tech industry associations, Microsoft, and employees of rival companies, the camp supporting Anthropic has expanded from the industry to the judiciary.

The government's counterattack is also escalating. Deputy Defense Minister Emil Michael referred to Anthropic as "hostile" in negotiations in the document, stating that its position is "not fact-based, but for public image management." Anthropic's CFO stated in legal documents that revenue loss by 2026 could be in the "billions of dollars." The hearing on March 24 is defining the legal boundaries of a new issue: whether AI companies can impose conditions on government clients' use.

4|On Day 20 of Iran War, Oil Prices Breathe But $200 Warning Still Looms

WTI fell to $95.50 on Monday, down 5.3%, triggered by Trump discussing a plan to escort ships in the Strait of Hormuz. However, analysts' warnings have not been retracted. According to CNBC, traders believe $200 is not out of the question. Capital Economics warns that if the war continues for three months, the average Brent price could reach $150.

The physical boundaries of the conflict are still expanding. Azerbaijan has deployed troops to the Iran border citing possible internal security collapse in Iran. Qatar suspended LNG production on March 2 due to drone attacks (supplying 20% of global LNG). The 11 countries currently involved in major conflicts control 51% of global oil production capacity and 56% of natural gas capacity. The brief oil price drop seems more like a breather than a turning point.

5|Another Zero Added to Cloud Giants' GPU Arms Race

AWS 在 GTC 上宣布跨全球區域部署超過 100 萬顆 NVIDIA GPU。同一天微軟 Azure 展示了液冷 Grace Blackwell GPU 的部署方案,Nemotron 模型接入 Foundry,Oracle 則通過 cuVS 庫接入 GPU 加速向量搜索。

三家雲巨頭在同一周內密集亮牌,競爭焦點已經從「誰的模型更好」滑向「誰控制更多推理算力」。NVIDIA 是共同的供應商,但每家的部署架構、冷卻方案和模型接入路徑正在分化。算力基建的規模戰不再是遠期預期,100 萬顆 GPU 是一個正在兌現的數字。
