 comes from extension during periods of rising interest rates or contraction in the form of more rapid prepayments during periods of falling interest rates. We evaluate this risk through extensive modeling of risk both before making an investment and throughout the life of the security. Our best estimate of the duration of the combined residential mortgage-backed securities portfolio held in investment and AFS securities was 3.5 years as of June 30, 2025, consistent with the measure as of March 31, 2025. Management estimates the duration extends to 4.2 years assuming an immediate 200 basis point upward shock. The estimated duration contracts to 2.3 years assuming a 200 basis point decline in the current rate environment. The duration of the total investment portfolio is 3.2 years, extending to 3.7 years in an upward shock of 200 basis points and contracting to 2.5 years in a down 200 basis point shock scenario. Management also regularly monitors the impact of interest rate risk on the AFS securities portfolio on our tangible equity ratio under various shock scenarios.

Loans

The aggregate loan portfolio before allowance for loan losses totaled $24.3 billion at June 30, 2025, an increase of $602 million compared to March 31, 2025, largely due to increases in commercial real estate loans and loans to individuals. Decreases in energy loan and services loan balances were largely offset by increases in general business and healthcare loans.
