Changes that took effect in the last 12 months, recorded so far: the FDIC often records a change weeks or months late, so these counts can still grow. The bar shows openings (green) against closings (red). Office count from the FDIC office list, read Nov 1, 2026; a branch stays listed until its bank reports the closing. Credit unions are not included (most are federally insured by the NCUA, not the FDIC).
