Cornerstone Bank: Securities Portfolio

Data as of · Call Report Schedule RC-B How we update

The investment portfolio: what the bank owns, how it is split between available-for-sale and held-to-maturity, and the unrealized gain or loss sitting in it. Unrealized losses on held-to-maturity securities do not run through capital, which is why the ratio to equity is worth watching.

The standout move of Q2 2026 was in Unrealized gain/(loss) to equity: 2.35 percentage points higher than in Q1 2026, at -15.03%.
