Deposit HHI
see the caveat below
Read the deposit HHI here with care. Machias Savings Bank books 63.6% of this county’s SOD deposits from 5 of 18 branch offices (27.8% of them). The Fed calls this pattern central booking. The deposit HHI here reads 4,376, the branch-count HHI 2,160. These pages lead with the branch measure, which central booking cannot move.

Concentration, 19942025

Branch-count HHI squares each institution’s share of the county’s branch offices; deposit HHI squares its share of county deposits. The bands are the 2010 Horizontal Merger Guidelines classification, the dashed line the 1,800 level above which the Federal Reserve reviews a merger centrally. In 2025 this market is moderately concentrated on branches (2,160) and highly concentrated on deposits (4,376).
