The Affordable Care Act brings an unprecedented level of scrutiny and transparency to health insurance rate increases. Evidence suggests that the Affordable Care Act contributed to a reduction in the rate of increase in premiums in the individual market since 2010. The proportion of rate filings in which the requested increase was 10 percent or more declined from 75 percent in 2010 to 34 percent in 2012, consistent with the increased scrutiny that such requests now receive. Available data for 2013 suggest that this pattern of slower premium growth has been maintained so far in 2013, with only 14 percent of requested rates at 10 percent or more. In addition, the average premium increase in 2012 was 30 percent below that in 2010.
