Indiana Economy at a Glance
Indiana’s Key Economic Sectors
Economic Drivers & Political Stakes
Japanese Transplants Caught in the Trade War
Indiana’s auto sector is dominated by Japanese-brand manufacturers who chose Indiana for its central location, business-friendly regulatory environment, and workforce. Subaru’s Lafayette plant is that company’s largest manufacturing facility outside Japan. Honda’s Greensburg plant was its first US production facility to be fully electrification-capable. Toyota’s Princeton plant makes the Sequoia and Highlander. These plants are deeply integrated into global supply chains — components arrive from Japan, Mexico, and across the Midwest daily. Auto tariffs disrupt this supply chain both directly (tariffs on imported parts raise costs) and indirectly (if Japan retaliates against US goods, demand for US-made Japanese-brand vehicles in Japanese export markets could fall). Indiana’s Republican senators support the tariff policies, but their auto worker constituents bear the risk.
GLP-1 Drugs and Indiana’s Pharmaceutical Renaissance
Eli Lilly’s development of tirzepatide (Mounjaro for diabetes, Zepbound for weight loss) has been one of the pharmaceutical industry’s most extraordinary recent stories. The drug’s commercial success drove Lilly’s market capitalization above $700 billion in 2024, making it briefly the world’s most valuable pharmaceutical company. The company has announced over $9 billion in new manufacturing investments in Indiana, including a massive new production campus in Boone County (Lebanon, Indiana). These investments will create thousands of high-wage manufacturing and R&D jobs in central Indiana over the coming decade. The political context: Lilly is headquartered in a deep-red state that provides favorable tax treatment, but the company has publicly navigated tensions over drug pricing that put it at odds with MAGA populism, which has attacked pharmaceutical pricing even as it champions deregulation.
Corn, Soybeans, and the Political Loyalty Over Economics
Indiana is a major corn and soybean state, with both crops deeply integrated into global commodity markets. Soybeans are the clearest case of tariff paradox: Indiana farmers depend on Chinese buyers for a substantial portion of their soybean revenue, yet they vote overwhelmingly for politicians who support the tariff policies that trigger Chinese agricultural retaliation. During the 2018-2019 trade war, Indiana soybean prices dropped sharply and the federal government distributed over $8 billion nationally in trade war compensation payments (Market Facilitation Payments) to offset losses. The payments substituted for market revenue but could not fully compensate for lost long-term trade relationships. China diversified to Brazilian soybeans during the dispute, permanently shifting some market share. The pattern is repeating in 2025 as new tariff cycles begin, with Indiana farmers again caught between economic pain and partisan loyalty.
