American Samoa
Branch-office deposits reported to the FDIC Summary of Deposits survey by institutions operating in American Samoa, June 30 of each survey year, 1994–2023. Dollar figures are the survey’s thousands-of-USD unit displayed as $B/$T. American Samoa is not one of the 50 states; small jurisdictions with few reporting institutions carry structurally high HHIs.
Coverage note. The latest survey year with branches reported in American Samoa is 2023; the survey’s latest year overall is 2025. All latest-year figures on this page are as of June 30, 2023.

Deposit concentration (HHI)
Statewide institution-share HHI: the sum of squared percent shares of each institution’s in-state deposits, 0–10,000. The shaded bands are the agencies’ 2010 Horizontal Merger Guidelines classification (section 5.3): unconcentrated below 1,500, moderately concentrated 1,500–2,500, highly concentrated above 2,500. The dashed line marks the 2023 Merger Guidelines threshold, under which markets with an HHI above 1,800 are highly concentrated (Guideline 1). American Samoa’s HHI is 10000 in 2023 (highly concentrated on the 2010 bands), against 5002 in 1994 and a span peak of 10000 in 2020. A statewide HHI is descriptive: merger review defines banking markets locally, not by state.

County concentration extremes, 2023
American Samoa has 1 county-level geography in the survey, shown by county-level deposit HHI. A county served by a single institution sits at the 10,000 ceiling by construction; thin county markets are the norm outside metros.
