Shuttering

I like to keep my English current, so I've been tracking the usages of the popular verb of today, "to shutter." Mostly it is used in place of "shut down." As in "The bison in Yellowstone have been shuttered since early March." 

Most of the talking heads on TV manage to work "shutter" in at some point, but this morning a news reader on CNN asked, "When do we start reshuttering the economy?"  

God only reknows.
