The US Federal Crop Insurance Program has become the primary risk management tool for American farmers. It provides insurance for over 128 crops across more than 80% of planted acreage for the top 10 crops. The program began in the 1930s during the Great Depression and Dust Bowl to promote economic stability in agriculture. It has since expanded through public-private partnerships and increased subsidies. The program is administered by the USDA and involves private insurers. It enables farmers to obtain loans and insures against revenue losses from weather and prices. Recent farm bills aim to further expand the program's role in agricultural policy.
