关税大战再起？特朗普瞄准加拿大化肥、印度大米，全球粮价又要变天？

Core Viewpoint - The Trump administration is considering imposing tariffs on Canadian fertilizers and Indian rice to support domestic industries, raising concerns about potential global food price increases and the impact on American farmers [1][3]. Group 1: Tariff Targets and Rationale - The proposed tariffs target Canadian fertilizers and Indian rice, which are critical imports for the U.S. agricultural sector. Canada is the world's largest producer of potash, holding 45% of global reserves, while India is the leading rice exporter, accounting for 40% of global exports [3]. - The U.S. agricultural sector has faced challenges, with farm bankruptcies reaching 259 from April 2024 to March 2025, nearly doubling from the previous year, and farmers experiencing losses of $100-200 per acre [3]. Group 2: Economic and Political Considerations - The tariffs reflect a dual strategy of economic protectionism and geopolitical maneuvering. The U.S. aims to reduce its trade deficit with India, which reached $45.7 billion in 2024, a 5.4% increase from 2023, while also pressuring India regarding its imports of Russian oil [5]. - The tariffs may also serve as a response to previous trade disputes with Canada, particularly regarding automotive tariffs [5]. Group 3: Potential Impact on Farmers and Global Markets - There is skepticism about whether American farmers will benefit from the tariffs, as previous tariff policies have hindered U.S. agricultural exports, particularly to major buyers like China. Increased fertilizer costs could further burden farmers [6]. - The tariffs could have widespread repercussions. For Canada, the fertilizer industry supports 76,000 jobs and contributes 2% to total exports. A loss of the U.S. market could lead to retaliatory tariffs on U.S. agricultural products [8]. - For India, reduced rice exports could disrupt global supply chains, forcing India to seek new markets in Europe and Africa, potentially reshaping the global rice supply-demand landscape [8]. Group 4: Historical Context and Risks - Historical precedents suggest that U.S. tariff policies can have detrimental effects, as seen with the Smoot-Hawley Tariff Act of 1930, which led to a significant decline in global trade and increased unemployment [11]. - The current tariff strategy may repeat past mistakes, risking U.S. agricultural exports and stifling innovation in domestic industries due to prolonged protectionism [11].
