Citi(US:C) 华尔街见闻·2025-11-09 12:25Core Viewpoint - A legal challenge against the Trump administration's key tariff powers is leading the market to anticipate a significant, albeit possibly temporary, reversal of trade barriers [1][5]. Group 1: Legal Challenge and Market Reaction - The market's expectation of the Trump administration winning the IEEPA tariff case has significantly decreased, with the probability dropping from approximately 40% to 27% following preliminary comments from judges during the hearing [4][5]. - The market sentiment is shifting towards the likelihood that the Supreme Court will overturn the IEEPA-based tariff policy, which is a key variable affecting current market emotions [5][6]. Group 2: Alternative Legal Avenues - Despite setbacks in court, the Trump administration still has other legal avenues to impose tariffs, as indicated by Treasury Secretary Bessent's optimism and readiness to utilize alternative legal authorizations [6]. - Potential alternative measures include Section 122, allowing a broad 15% tariff within 150 days, Section 338, permitting tariffs up to 50% on countries discriminating against U.S. businesses, and the concept of "licensing fees" for tariffs, although the latter faced skepticism during the hearing [7][8][9]. Group 3: Short-term Winners and Losers - If the IEEPA tariffs are overturned, the effective tariff rate in the U.S. is expected to drop from an estimated 12.5% to around 9% [11]. - The biggest beneficiaries in the short term are likely to be economies heavily reliant on trade with the U.S. and most affected by the IEEPA tariffs, particularly Vietnam and Mexico [11][15]. - Other countries, such as India, may also see significant tariff reductions, while the EU and the UK are expected to benefit the least [15]. Group 4: Market Performance and Trading Strategies - On the day of the hearing, the market showed a favorable response, with the Mexican peso and Brazilian real appreciating, aligning with the analysis of potential winners [13]. - The Russell 2000 small-cap index outperformed the S&P 500, reflecting a positive market sentiment towards tariffs [16]. - One-year inflation swap rates fell by over 5 basis points, indicating that investors quickly adjusted their expectations regarding inflation pressures from tariffed goods [16].
