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). Delaware’s HHI is 4836 in 2025 (highly concentrated on the 2010 bands), against 910 in 1994 and a span peak of 4836 in 2025. A statewide HHI is descriptive: merger review defines banking markets locally, not by state.
