bankroll (n.)

"financial institution," late 15c., originally "money-dealer's counter or shop," from Old Italian banca and also from French banque (itself from the Italian word), both meaning "table," from a Germanic source (such as Old High German bank "bench, moneylender's table"), from Proto-Germanic *bankiz- "shelf," *bankon- (see bank (n.2)). The etymological notion is of the moneylender's exchange table.
