The ACA significantly altered the rules governing the individual insurance market, and the general effect was to lower premiums for older and less healthy people and raise premiums for younger and healthier people. To induce younger and healthier people to enroll, the law contained the individual mandate and subsidies for both buyers and, for the first few years of the program, sellers of insurance in the form of premium stabilization programs.

This study analyzes data from HHS from 2014, the first year of the ACA’s implementation, and finds that insurers suffered significant losses despite eventually receiving much larger payments from the law’s reinsurance program (one of the premium stabilization programs) than they expected when setting their 2014 premiums. Given the same population and same utilization of services from that population, insurers would have had to price average premiums more than 25 percent higher to avoid losses in the absence of the reinsurance program.

While insurers’ performance varied significantly across carriers and states, the large overall losses in 2014 raise questions about the long-term stability of the changes made by the ACA, particularly after 2016 when the reinsurance and risk corridor programs end and premium revenue must be sufficient to cover expenses.
