The Muunilinst Banking Clan, alternatively called San Hill's InterGalactic Banking Clan, constituted a branch of the InterGalactic Banking Clan with its headquarters on the planet of Muunilinst.
A key component of the larger InterGalactic Banking Clan, a significant financial institution throughout the galaxy, was the Muunilinst Banking Clan. San Hill directly oversaw this particular banking clan division, holding the position of chairman for the entire InterGalactic Banking Clan. Its base of operations was situated on the planet Muunilinst, found within the Outer Rim Territories. As the Clone Wars began, Hill secretly forged an alliance between the Banking Clan and Count Dooku's Confederacy of Independent Systems, providing IG-227 Hailfire-class droid tanks for the expanding Separatist Droid Army and offering monetary support to the Confederacy. Consequently, the Muunilinst Banking Clan played a role in financing the construction of the Death Star battle station.
Hill's arrangement was not exclusive, as the IGBC engaged in commerce with both the Republic and the Confederacy during the subsequent Clone Wars, although the organization leaned towards the CIS. Even after the Office of the Chancellor assumed control of the IGBC, the Muunilinst Banking Clan persisted in backing the Separatists, evidenced by Hill's continued presence on the Confederacy's leadership council, but became entrenched on the planet Mygeeto, a Banking Clan stronghold. However, the newly established Galactic Empire seized its assets following Hill's abrupt execution by the Sith Lord Darth Vader on Mustafar.
The Banking Clan, initially identified simply as such, made its debut appearance in the 2002 motion picture Star Wars: Episode II Attack of the Clones as the Muunilinst Banking Clan.
