The South Korean government allowed companies to increase premiums for car insurance by 3.5% due to the widespread car damage. Due to storm damage, 34 companies were forced to temporarily close. Loss of production and disruptions were expected to subtract 0.5% from the forecast economic growth in 2003. The Consumer Confidence Index dropped to its lowest level in five years, largely due to the typhoon damage and weakened economic conditions. Following the strikes of Rusa and Maemi in consecutive years, the South Korean government worked on disaster management and mitigation programs. In March 2004, the government passed the "Emergency and Safety Management Basic Act", largely due to the storm as well as the Daegu metro fire, which effectively set up a nationwide emergency management system. The Gupo bridge damaged during the storm was repaired in 2007.
