Core Viewpoint - The ongoing chip industry dynamics reflect a shift in power, with the U.S. attempting to regain market share while China accelerates its self-sufficiency in chip production [2][8]. Group 1: U.S. Policy Changes - The U.S. initially imposed strict bans on high-tech chip sales to China, but by July 2025, the Trump administration began to relax some restrictions, allowing specific AI chips to be sold under the condition of a 15% revenue share to the U.S. Treasury [2][4]. - Major U.S. chip companies like NVIDIA and AMD, which previously relied heavily on the Chinese market for over 20% of their revenue, are eager to re-enter the market following the easing of restrictions [4][5]. Group 2: China's Response - In response to U.S. restrictions, China has committed to increasing its self-sufficiency in chip production, aiming to double its domestic chip supply by the end of 2025, supported by significant government investment [4][5]. - Chinese companies, including Huawei and SMIC, are advancing their technology, with Huawei's Ascend 910B chip already in use in local data centers, demonstrating competitive performance [4][5]. Group 3: Market Dynamics - The Chinese government has initiated anti-monopoly investigations against NVIDIA, indicating a tightening regulatory environment for foreign chip companies [4][5]. - As of September 2023, China has begun investigations into U.S. chips for potential discrimination and dumping, complicating the re-entry of U.S. firms into the Chinese market [5][6]. Group 4: Impact on Global Chip Companies - Companies like Samsung and TSMC are facing challenges due to U.S. policy changes, with Samsung reporting a 10% drop in third-quarter revenue as a result of lost market share in China [7][8]. - The shift in the chip industry landscape has led to a bifurcation of the global supply chain, with the U.S. and China emerging as two distinct poles [8][10]. Group 5: Long-term Implications - The initial U.S. strategy aimed at stifling China's AI development has inadvertently accelerated China's innovation and self-reliance in chip technology [10]. - U.S. chip companies are now facing higher barriers to entry in China, as the country enhances its domestic capabilities and reduces reliance on foreign technology [10].

Core Viewpoint - The ongoing geopolitical tensions between the US and China are significantly impacting TSMC, a leading player in the semiconductor industry, particularly following the US Department of Commerce's revocation of the "Verified End User" (VEU) exemption for TSMC and other companies operating in China [1][2][15] Group 1: Impact of VEU Revocation - The revocation of the VEU exemption will complicate TSMC's supply chain, increasing operational costs and reducing efficiency due to the need for individual export licenses for each shipment [1][4] - TSMC's Nanjing factory, which handles a substantial volume of mature process orders, may face significant disruptions, affecting the supply chains of various international chip manufacturers [8][10] - The US Department of Commerce anticipates an additional 1,000 export license applications annually due to the revocation, highlighting the increased administrative burden on companies [4][10] Group 2: Strategic Positioning of TSMC - TSMC is navigating a delicate balance between maintaining its business interests and managing relationships with both the US and Chinese markets, reflecting a cautious approach in its communications [2][6] - The tightening of US semiconductor export controls is part of a broader strategy to curb China's technological advancements, with TSMC caught in the middle of this geopolitical struggle [6][15] - The company's market capitalization has surged to over $1 trillion, driven by the rising demand for advanced chips, particularly in AI applications, positioning it as a key player in the global tech landscape [4][10] Group 3: Future Outlook - The ongoing policy changes create heightened uncertainty and volatility in the semiconductor sector, compelling companies to adopt a more conservative investment stance [10][12] - The future of TSMC's VEU status and its negotiations with the US government remain uncertain, with potential implications for the global supply chain and the semiconductor industry at large [15][12] - The situation reflects a broader trend of "de-risking" within the global semiconductor supply chain, driven by national security concerns and the quest for technological independence [12][15]
