Marshall Islands
Branch-office deposits reported to the FDIC Summary of Deposits survey by institutions operating in Marshall Islands, June 30 of each survey year, 1994–2025.

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). Marshall Islands’s HHI is 10000 in 2025 (highly concentrated on the 2010 bands), against 5224 in 1994 and a span peak of 10000 in 2003. A statewide HHI is descriptive: merger review defines banking markets locally, not by state.
