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). Alaska’s HHI is 2678 in 2025 (highly concentrated on the 2010 bands), against 2588 in 1994 and a span peak of 4475 in 2009. A statewide HHI is descriptive: merger review defines banking markets locally, not by state.

County concentration extremes, 2025
The most and least concentrated of Alaska’s 24 counties in the survey, 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.
Most concentrated
| County | HHI | Inst. | Branches |
|---|---|---|---|
| Aleutians West | 10000 | 1 | 1 |
| Bristol Bay | 10000 | 1 | 1 |
| Denali | 10000 | 1 | 1 |
| Dillingham | 10000 | 1 | 1 |
| Haines | 10000 | 1 | 1 |
Least concentrated
| County | HHI | Inst. | Branches |
|---|---|---|---|
| Fairbanks North Star | 1969 | 6 | 17 |
| Juneau | 2403 | 5 | 9 |
| Sitka | 2523 | 4 | 4 |
