Puerto Rico
Branch-office deposits reported to the FDIC Summary of Deposits survey by institutions operating in Puerto Rico, June 30 of each survey year, 1994–2025. Dollar figures are the survey’s thousands-of-USD unit displayed as $B/$T. Puerto Rico is not one of the 50 states; small jurisdictions with few reporting institutions carry structurally high HHIs.
Deposits, 1994–2025
Office-assigned deposits at branches in Puerto Rico went from $21.30B in 1994 to $83.79B in 2025, nominal.

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). Puerto Rico’s HHI is 4606 in 2025 (highly concentrated on the 2010 bands), against 1589 in 1994 and a span peak of 4717 in 2024. A statewide HHI is descriptive: merger review defines banking markets locally, not by state.

County concentration extremes, 2025
The most and least concentrated of Puerto Rico’s 76 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.

|---|---|---|---|
| Adjuntas | 10000 | 1 | 1 |
| Aguas Buenas | 10000 | 1 | 1 |
| Anasco | 10000 | 1 | 1 |
| Arroyo | 10000 | 1 | 1 |
