Home State and host State are defined for the section
What the document says“(1) Home state.--The term "home State" means the State by which the depository institution is chartered. (2) Host state.--The term "host State" means a State in which a depository institution establishes a branch, solicits customers, or otherwise engages in business activities, other than the home State.”
Subsection (e). The two terms are defined for this section. Section 7(f) uses the same pair to work out which State's laws apply to an out-of-State State qualified payment stablecoin issuer.
What the document actually says“(1) Home state.--The term "home State" means the State by which the depository institution is chartered. (2) Host state.--The term "host State" means a State in which a depository institution establishes a branch, solicits customers, or otherwise engages in business activities, other than the home State.”
A bank's home state is the one that chartered it. A host state is any other state where it works. That covers a branch or a search for customers.
The pair of terms matters for which laws apply. Part 7 uses them the same way. There they settle which state's rules a maker follows.
