Nvidia遭美制裁!中美晶片戰火升級,股價暴跌




美國晶片出口限制重擊英偉達,貿易戰升級

晶片巨頭英偉達(Nvidia)於周三股價大幅下跌,原因是美國政府收緊對中國出口的人工智能晶片限制,可能導致該公司本季度損失高達55億美元。

這一舉措是美國和中國之間貿易和技術限制升級的一部分,已經令市場因關稅不確定性和地緣政治緊張局勢而保持警惕。

特朗普貿易戰衝擊晶片出口

美國政府於周二晚些時候告知英偉達,其針對中國的H20晶片——一款專為符合此前限制而設計的強大圖形處理器(GPU),現需出口許可證。英偉達隨後公開披露了這一變化,令一些中國大客戶措手不及。

據路透社報道,像百度、騰訊和阿里巴巴這樣的大客戶此前已訂購了價值160億美元的H20晶片,預計年底前交付。然而,美國政府現已將許可證要求無限期延長,導致英偉達不得不減值庫存、取消承諾,並計入44億美元的損失。

H20晶片限制是在貿易緊張局勢升級的背景下出台的。上周,美國總統特朗普將對中國進口商品的關稅提高至145%,北京則以對美國商品徵收125%的關稅作為回應。

儘管特朗普的一些更廣泛的關稅措施被推遲三個月,但市場仍對長期趨勢感到擔憂。

美國行動旨在阻止中國獲取高端人工智能硬體

美國的這一舉動是阻止中國獲取高端人工智能硬體的一系列行動之一,這些硬體在軍事和技術競爭中至關重要。

英偉達的股價在周二盤後交易中暴跌逾6%,導致納斯達克期貨周三早晨下跌1.1%。標準普爾500指數期貨下跌0.5%,而道瓊斯期貨持平,顯示科技股受到的衝擊。

半導體同行AMD和英特爾也下跌,荷蘭設備巨頭ASML因未達盈利預期而下跌逾6%。

市場擔憂升級

“出口限制是美中競爭的新武器,英偉達被夾在交叉火力中,”AJ Bell的分析師Russ Mould表示。“55億美元的損失標誌著這場互相報復的新篇章。”

Trade Nation的高級分析師David Morrison補充說:“市場此前相對平靜,但英偉達的盤後衝擊改變了基調。看起來這是風暴中心,而不是風暴前的寧靜。”

亞洲市場方面,科技股下跌。香港恒生指數下跌2.2%,日本Topix指數下跌逾1%。中國主要晶片客戶和供應商因擔心美國出口限制蔓延而下跌。

“這種不確定性對每個人都不利,”Hargreaves Lansdown的分析師Steve Clayton表示。“英偉達的限制創造了更廣泛的疑慮,關於美中貿易關係的未來走向。”

Quilter Cheviot的全球科技分析師Ben Barringer指出,這一影響廣泛。

他說:“英偉達的許可證要求影響了ASML等供應鏈下游企業。13億美元的收入衝擊並不災難性,但這是在已經因波動性而承壓的環境中發生的。”

與此同時,白宮的貿易立場仍然難以預測。美國財政部長斯科特·貝森(Scott Bessent)預計下周將與韓國貿易部長會面,而中國任命了一位新的首席貿易談判代表,呼籲華盛頓在重新開展正式談判之前給予更多“尊重”。

正如一位分析師所說,“這不僅僅是一個晶片故事——這是一個具有科技標籤的地緣政治故事。”

作為編輯,我認為這篇文章揭示了美國對中國晶片出口限制的最新舉措對科技行業的深遠影響。英偉達作為領先的晶片供應商,其股價大幅下跌,反映出市場對貿易戰升級的擔憂。美國政府的這一行動不僅影響英偉達,也對整個科技行業產生了連鎖反應。

此外,這一事件也凸顯了美中貿易關係的複雜性和不確定性。美國政府的出口限制不僅影響中國,也影響其他國家,如韓國和日本。隨著貿易戰的升級,市場將繼續保持警惕,關注未來可能出現的變化。

值得注意的是,這一事件也反映了美國政府對中國科技行業的擔憂。美國政府試圖限制中國獲取高端人工智能硬體,凸顯了科技競爭在國際關係中的重要性。

總之,這篇文章提供了對美國晶片出口限制對科技行業影響的深入分析,也凸顯了美中貿易關係的複雜性和不確定性。

A dynamic, ultra-realistic action shot of a snowboarder performing a high-air jump on a snowy mountain slope. The rider wears a bright green winter jacket, black snow pants, gloves, and a dark beanie, with reflective goggles catching the cold mountain light. A cloud of visible breath escapes from the rider’s mouth in the freezing air. Snow explodes upward from the snowboard, creating sharp, frozen particles suspended mid-air. The background features a dramatic high-altitude landscape with forested slopes and distant mountains under soft, cold blue lighting. Capture cinematic contrast, DSLR realism, 85mm lens, f/2.8, crisp details, slow-motion energy, dynamic composition, atmospheric depth, high-clarity sports photography. Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a captivating studio portrait of a woman with long, wavy brown hair, seated gracefully on a stool in a thoughtful pose.

She wears delicate earrings and a gold bracelet that add a touch of sparkle to her overall look. The lighting is soft and diffused, creating a warm and flattering effect that emphasizes her beauty and the flowing lines of the gown. The background is a plain, brown, providing a warm and neutral backdrop. *** The composition is a full shot, capturing her from head to toe, framed vertically to accentuate her height and the flowing lines of the gown. The model is positioned in the center of the frame, creating a balanced and harmonious composition. The overall style is classic, elegant, and timeless, reminiscent of portrait photography, evoking a sense of grace, sophistication, and enduring beauty. Use the original face exactly as it is, without changing a details. A female model with sharp features, defined cheekbones, and intense, direct eye contact (though eyes are slightly in shadow from the hat).
