Is there some form of standardized banking throughout the Realms? Even something localized among the three major cities of the Sword Coast (Neverwinter, Waterdeep, Baldur’s Gate)? If so, how are funds made available and account balances known? My players are asking. See the “Money Matters” chapter of the "Ed Greenwood Presents Elminster’s Forgotten Realms" sourcebook (no, I didn’t come up with that title!).
It covers temples offering banking, rollcoins, moneylenders, and manycoins businesses. (In some places, guilds also bank.)#Realmslore
