Fulcrum Bank
The Fulcrum, Bank of the Barony of Baudelaire, is the first and final authority on money in the region. They mint coins, stamping it with the profile of the current Baron (currency weights and composition is established by the Empire but regions have freedom in the format and how they go about minting) and issue it into circulation. They also exchange money, to and from foreign and domestic currencies, taking a small percent as fee. But most of the bank's profit comes from the loans they issue, typically making safer long term investments rather than the aggressive business ventures the Guild of Speculators is known for.
