Illinois Economy: Finance, Agriculture, and Manufacturing

Illinois has the fifth-largest GDP of any US state — a powerhouse of finance, agriculture, manufacturing, and healthcare anchored by the Chicago metro.

Financial Services and Trading
Chicago is the world capital of futures and derivatives trading. The CME Group (formerly Chicago Mercantile Exchange and the Chicago Board of Trade) operates the world's largest futures exchange — trading agricultural commodities, financial instruments, interest rates, and currency futures. The CBOE (Chicago Board Options Exchange) dominates equity options trading. The Chicago Federal Reserve and the Federal Home Loan Bank are major institutions. The Chicago Mercantile Exchange (1898) grew out of the 19th-century grain trading that tied Chicago to the Corn Belt.

Agriculture
Illinois consistently ranks #1 or #2 nationally in soybean production and #1 or #2 in corn. The Corn Belt's richest soils run through central Illinois. Agriculture in Illinois is almost entirely large-scale commodity farming — soybeans and corn grown for export and processing. The Port of Chicago and the Illinois waterway system allow barge transport to the Gulf.

Manufacturing
Illinois is a major manufacturing state — Caterpillar (construction equipment, headquartered in Deerfield/Peoria area), Deere & Company (agricultural equipment, Moline), Fermilab (Batavia — a major particle physics laboratory), Abbott Laboratories, and food processing (Archer Daniels Midland, headquartered in Chicago) are major employers. The Illinois-Indiana steel corridor (Chicago Southland and Hammond, IN) is the largest steel-producing area in the US.

Technology and Startups
Chicago has developed a significant technology sector — particularly in fintech (influenced by the trading industry), food technology, and enterprise software. The 1871 incubator in the Merchandise Mart and the Illinois Technology Association support the startup ecosystem. Groupon and CareerBuilder were Chicago startup success stories.

Fiscal Challenges
Illinois has one of the most severe public pension crises of any state — unfunded pension liabilities exceed $200 billion. The state has among the highest property tax rates in the US. These fiscal challenges have contributed to population outmigration.
