What this series measures

Largest reported holding-company or insured-institution share of 2025 FDIC branch deposits within each county or county equivalent.

County rows are screens of positive FDIC Summary of Deposits branch balances grouped to the reported top bank holding company when available and otherwise to the insured institution. Branch-reported deposits may not represent where every customer lives or competes, county boundaries may not match a banking market, deposits are not every banking product, and these screens are not legal market definitions.

Interpretation boundaryCounty rows are screens of positive FDIC Summary of Deposits branch balances grouped to the reported top bank holding company when available and otherwise to the insured institution. Branch-reported deposits may not represent where every customer lives or competes, county boundaries may not match a banking market, deposits are not every banking product, and these screens are not legal market definitions. Association between the two measures is mechanical context, not a finding about competition, access, prices, or consumer outcomes.

    Antitrust Radar sums positive June 30, 2025 branch deposits within each FDIC-reported county or county equivalent, groups branches to the FDIC-reported top bank holding company when available and otherwise to the insured institution certificate, then calculates shares and HHI from those grouped balances.

Indicator evidence guardrail

One measure, one contract

This profile documents one bounded indicator at a time. Its ranks, distributions, histories, and paired views remain inside the stated universe, period basis, source, unit, and methodology; they are descriptive research screens, not legal findings or components of a composite score.

County rows are screens of positive FDIC Summary of Deposits branch balances grouped to the reported top bank holding company when available and otherwise to the insured institution. Branch-reported deposits may not represent where every customer lives or competes, county boundaries may not match a banking market, deposits are not every banking product, and these screens are not legal market definitions.
