Bank of Marin: 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 Securities to total assets: 1.66 percentage points lower than in Q1 2026, at 32.23%.
