Demand surge
Demand surge is the increase in prices for labor and materials following a catastrophe, as construction material and contractors' costs increase along with the increased demand for repairs and replacement construction.

Through the June 2022 release, the US-derived demand surge (legacy) methodology was event-based and used the industry loss across the entire modeled region. It was also based on a limited number of U.S. models. The new demand surge methodology is country-specific and accounts for the whole year instead of for each event individually. The initial release of the new demand surge model supports select European models. The remaining countries and regions continue to use the existing US-derived demand surge model. Support for the new country-specific demand surge models will be extended to non-European models in future releases.

When you create a custom curve, you can paste data into the grid, revert to the last saved version, and clear the grid. Currency is established in .
Set loss defaults for demand surge in the Demand Surge pane. Note that you cannot change settings for the Analyze Re default regions. The options to change settings become available only after you create a custom surge.
