The severe flooding in United States — Hawaii, particularly on United States — Oʻahu, and the threat of Wahiawa Dam failure, are expected to have a significant negative impact on the state's economy, with estimated damages exceeding $1 billion. This will likely affect the insurance industry due to widespread property damage, the tourism industry due to disruptions and negative publicity, and potentially the agriculture sector given the historical context of the dam's use. The financial burden on United States — Hawaii and the potential for federal aid will be closely watched by market participants.

United States — Hawaii is experiencing its worst flooding in over 20 years, primarily affecting United States — Oʻahu, due to heavy rains on already saturated ground. The severe weather has led to widespread flash flooding, inundating streets, damaging homes, and prompting evacuation orders for thousands of residents in towns north of United States — Honolulu. A major concern is the 120-year-old Wahiawa Dam, which reached high levels and was at risk of imminent failure, although water levels later receded. Governor Joshua Green activated the United States — Hawaii National Guard and estimated the storm's cost could exceed $1 billion, securing assurances of federal support. The flooding has also impacted United States — Maui, with evacuation warnings issued for United States — Lahaina, Hawaii due to nearing capacity retention basins. The state had previously passed legislation to acquire and repair Wahiawa Dam from Dole plc, but the transfer is not yet complete.
